Infrastructure building in the UK is a complicated business – it involves planning, financing, constructing and maintaining roads, railways, stations, tunnels and energy networks – and the country has a big issue. It’s costing us more to deliver this infrastructure here than in almost any other comparable European economy, and the gap is getting bigger. Now the Competition and Markets Authority has done some research into road and rail civil engineering and the evidence is clear: long-standing problems with procurement, governance and risk allocation are costing the UK billions every year.
For all the people in the UK who are involved with planning, building and maintaining the country’s infrastructure – that’s policymakers, civil engineers, professionals working in the sector, government agencies, investors and loads of other folk – this article looks at where these extra costs come from and what needs to change. We look at international cost comparisons with other economies, at how we plan our projects and how we manage risk, at design standards, construction complexity, innovation and productivity, at whether our buildings and public services are sustainable and resilient to climate change, before suggesting practical ways to make our delivery models and long-term strategies better.
Infrastructure investment is very important – it drives economic growth, helps with energy security and improves people’s quality of life. But the UK is consistently overspending on its projects – we’re paying a 20-40% premium over what similar countries are paying on comparable schemes, and in some cases it’s much worse than that. Take HS2 for instance – that’s now projected to cost £87.7-102.7 billion, roughly two to three times what we originally thought it would cost. And Crossrail? Originally budgeted at £14.8 billion but it finished at £18.9 billion.
The CMA’s 2026 investigation gives us the clearest explanation yet of what is going wrong. Their main findings are worth taking a close look at:
- Short-term procurement is a major problem – it’s not just adding cost, it’s slowing down delivery and stopping innovation across the UK’s road and rail civil engineering projects.
- Potential savings of up to £5 billion a year could be made by working to longer-term frameworks, creating programme-based alliances and using outcome-based specifications.
- Planning delays, over-specification and stop-start funding are almost as big a problem as the cost of materials and labour in driving up costs.
- Getting professional engineers involved in the decision-making process early on, sharing the risk and using context-based design standards, would make building infrastructure cheaper without compromising on safety.
- Preparing for climate change, reducing our carbon footprint and making our transport systems more modern all raise upfront costs but we can moderate those increases by planning ahead and using design innovation like green roofs and low-carbon paving.
Key Takeaways
Infrastructure building is about planning, financing, constructing and maintaining roads, railways, stations, tunnels and energy networks. And the UK has problems with all of these things. It’s not just that one stage of the process is being handled badly, it’s that all four stages are afflicted by deep-seated problems that add to each other. As a result the UK is one of the most expensive places in the developed world to build infrastructure.
Investment in infrastructure is vital for economic growth and energy security. Good infrastructure improves people’s quality of life and helps to create conditions that let the economy grow. But the UK regularly pays a 20-40% premium over what similar countries are paying on their projects, and in some cases it’s a lot more. Take HS2 for instance – that’s now projected to cost £87.7-102.7 billion, roughly two to three times what we originally thought it would cost. And Crossrail? Originally budgeted at £14.8 billion but it finished at £18.9 billion.
The CMA’s 2026 investigation is the clearest explanation yet of what is going wrong. Their findings are:
- We’re doing civil engineering projects on a short-term basis, which costs a lot, slows delivery and stifles innovation across UK road and rail projects.
- Reforming procurement and working to longer-term frameworks could unlock savings of up to £5 billion a year across the road and rail civil engineering projects – that’s a potential 10-25% reduction in current expenditure.
- Planning delays, over-specification and stop-start funding are major issues in driving up costs in the UK.
- Professional engineers need to be involved in policy and procurement decisions early on, and we need to share the risk and use context-based design standards to make delivery more cost effective.
- Preparing for climate change all raises upfront costs but we can moderate those increases by planning ahead and using design innovation like green roofs and low-carbon paving.
1. The CMA’s 2026 Findings: Why This Debate Matters Right Now
The Competition and Markets Authority did a thorough investigation into road and rail civil engineering back in 2026 – it was prompted by spiralling costs on schemes like HS2, the Transpennine Route Upgrade and the A303 Stonehenge tunnel. The conclusions were stark.
The CMA found that because we do infrastructure projects on a short-term basis, it’s costing a lot, slowing down delivery and stifling innovation across highways and rail civil engineering. We’re breaking projects down into loads of small packages, retendering each one separately – that creates duplicated overheads, adversarial behaviour and constant design churn. We’re not innovating because contractors can’t justify investing in modern methods, digital tools or research and development because they have no certainty of ongoing work.
The CMA’s research also estimated that reforming procurement and working to longer-term frameworks could unlock savings of up to £5 billion a year across the £19 billion or so that’s spent annually on UK road and rail civil engineering, excluding HS2. That’s a potential 10-25% reduction in current expenditure.
So – what’s preventing the UK from building high-quality, essential infrastructure more cheaply? And what needs to change?
2. How UK Infrastructure Costs Compare Internationally
International comparisons are not perfect, but the pattern is clear. The Institute of Economic Affairs did some analysis that was published in August 2026 – it found that HS2 Phase 1 has cost about £470 million per route-kilometre, making it one of the most expensive high-speed rail lines in the world. And the UK government’s own analysis found that, on average, European high-speed lines were costing £32 million per kilometre in 2011 prices – that rose to £43-61 million per kilometre in more urban, infrastructure-dense settings.Transport systems around the world, including Britain, involve roads, bridges, railways and airports – and in every single one of those categories, Britain ends up paying a premium. UK motorway costs come out at around 10-30% higher than equivalent schemes in the Netherlands or Germany – and that gap is particularly wide when you’re building junctions, earthworks or structures.
Crossrail, for example, cost £18.9 billion to build, with 42 kilometres of new tunnels and ten new stations. And UK station costs? Those are on average around 50% more expensive than similar ones in Spain – even after you factor in the difference in peak demand and structural complexity.
These are pretty big deals worldwide too – with infrastructure investments helping to drive over half of Africa’s growth between 1990 and 2005, for instance. And yet in Africa, governments need to be spending around 15% of their GDP just to sustain that growth, and in Sub-Saharan Africa, that amounts to around $9.4 billion a year on infrastructure. In telecommunications, investments in developing countries can return as much as 30-40%. In the US, public spending on infrastructure has bobbled between 2.3% and 3.6% of GDP since 1950 – and they currently come in as second-to-last place globally at 2.4% of GDP, with a projected under-investment of $2 trillion from 2016 to 2025. In Latin America, 3% of GDP is needed for infrastructure investment to meet demand, with a financing gap of about $24 billion as of 2005. And in the Asia-Pacific region, they need $228 billion annually to keep up but only manage to invest $48 billion, leaving an infrastructure gap of around $180 billion annually.
Now, labour costs, safety standards and urban density do all play a part in the UK premium – but they can’t explain why costs are two to six times higher in the UK, especially when you compare them to European projects in equivalent tricky terrain that somehow come out way cheaper.
3. Historical Context: Britain’s Journey to Depend on Expensive Workarounds
To understand where we are now, we need to take a step back to the 1980s, when a whole lot changed with waves of privatization, market-testing and outsourcing that fundamentally rewired how Britain’s infrastructure is planned and delivered.
Large teams of in-house designers and builders within government departments, local authorities and British Rail were disbanded and replaced with external consultants and contractors. Utilities got privatized – water supply, sewage treatment, electricity distribution – and responsibility for all that design, earthwork and structural work got fragmented across multiple private outfits, with the public sector retaining ever less technical know-how.
Milestones in all this include the introduction of the Private Finance Initiative back in the 1990s, which meant private finance came with higher risk premiums baked into the price. Then the 2000s brought design-and-build contracts where contractors took on both design and delivery risk – but at the same time, public oversight got whittled back. And then after 2010, alliancing models showed up on some rail projects – where parties all shared risk and reward – though they haven’t really taken off on any scale.
Now some of these shifts weren’t inherently bad on their own – but taken together, they created an ecosystem where no one single party is really in charge of the long game of whole networks – and that leads to transaction costs piling up, knowledge flying out of client organisations, and risk pricing rising at every single interface.
4. Fragmented Procurement: The CMA’s Main Beef
The real source of the problem, though, is fragmented procurement. UK clients have a tendency to split projects into loads of little packages on short-term contracts, with loads of tendering and retendering, and only a handful of long-term programme alliances or integrated frameworks. Each package needs its own mobilization, tender prep, management overhead and risk assessment.
And that fragmentation is a disaster for predictable reasons. Different contractors all re-interpret the requirements to fit their own needs, re-price risk for each package and very rarely get to build on any learning from previous phases. And rework? That’s just endemic. When separate outfits are handling the civils, structures, electricals and paving, it’s no surprise that interfaces get out of whack, standards diverge and rework is the inevitable result.
And all this gets even worse because of short, stop-start funding cycles – so, HM Treasury and the sponsoring departments are committing budgets on annual or bi-annual cycles, which just creates this ‘boom and bust’ in the market.
- Contractors load up on resources when funding flows in, then jettison them when the budgets get cut, destroying workforce continuity and raising unit costs. And supply chain partners can’t even invest in new plant or skills without having a steady long-term pipeline to rely on.
The CMA’s 2026 investigation basically said that all they need is a bit more long-term, outcome-based procurement with clearer pipelines, and that would let the construction industry put some real investment into modern gear, digital tools and workforce development – while also giving private investors enough confidence to back long-term infrastructure programmes, which would make schemes way more cost effective throughout their entire life cycle.
5. The Price of Stop-Start Investment and Political Volatility
We’ve had repeated stalling and cancellation of projects between 2010 and 2026, and that’s added up to a real cost on the nation’s infrastructure bill. They cancelled sections of HS2 north of Birmingham. Major road schemes got paused during changes of government. Rail electrification programmes got started, stopped and restarted.When projects come to a halt, the design teams break up, supply chain prices collapse and key experts jump ship. By the time the plans get revived, most of the earlier work has to be re-done, with an added price premium put on account of the possibility of even more disruption down the line. Infrastructure funding in the UK is supposed to be spread out over a variety of sources to reduce its reliance on the whims of politics. However, the truth is that we’re still almost entirely reliant on a single, Treasury-based allocation system.
This creates a huge amount of uncertainty and makes long-term strategic planning impossible. Local authorities and civil engineers can’t even begin to think about planning skills development, land acquisition or diversions for utilities with any real confidence when they’re constantly being told the future of major schemes is up in the air. Reliable transportation and stable power grids do make business more cost-effective but only when they’re delivered consistently and not in fits and starts.
International comparator states that have cross-party consensus on their national infrastructure strategies along with long-term transport and electricity generation plans plus stable funding agreements seem to manage to get an overall lower cost for their projects. That’s no accident.
6. Planning, Consenting and Legal Challenges
The UK’s planning and consenting process for major schemes is an arduous and time-consuming affair involving Development Consent Orders, Transport and Works Act Orders, and hybrid Bills. It’s an exercise that requires massive environmental assessments, public consultations and dealing with a long list of different statutory undertakers and regulatory bodies with an interest in heritage, habitats, water quality and net-zero obligations, plus lots of other things.
As a result, projects are bogged down in red tape for a very long time indeed. Between 2012 and 2021, the average time to get a decision on a Development Consent Order went up by a whopping 65%, from 2.6 years to 4.2 years. Some of these consent orders now tip the scales at an astonishing 90,000 pages or more. And while public participation and due process are of course absolutely vital, the duplication in consultation and assessment that does go on drives up professional fees through the roof.
The right to judicial review is another big headache. Between 2015 and 2022, eleven judicial reviews of road-related DCOs actually went on for an average of 437 days from the initial decision to the final outcome, with some projects incurring £100-£120 million extra in costs even when the original decision ultimately held up. Community engagement can really help keep disruption to a minimum in infrastructure projects if it’s done early and genuinely, but the current planning system seems to actually incentivise last-minute, adversarial challenges rather than early collaborative resolution.
If planning bodies were properly resourced, clearer national policy statements and earlier community engagement were put in place, we could probably cut down on the delays and still protect environmental standards and ensure local voices are heard. Unfortunately, when the approvals process does get slow and duplicative, it often ends up being the planning system itself that becomes the main obstacle to progress.
7. Risk Allocation: The Reason Everyone Prices for the Worst Case
UK contracts all too often throw a huge burden of construction, ground and interface risks onto the contractors. When faced with unknown utilities, contaminated land or unstable ground conditions on brownfield and railway sites, contractors are forced to add a load of contingency to their prices for earthworks, structures and complex paving phases just to protect themselves.
Some of the key dynamics at play include:
- Ground conditions are notoriously difficult to get a clear picture of at the tender stage, especially on sites that have had multiple different uses in the past. Contractors have to price for the worst-case scenario because their contracts penalise them if things go over budget.
- The adversarial culture that pervades contract negotiations and the strict penalty regimes that come with them actually discourage open discussion of emerging problems. Instead of working together to resolve issues in real time, things just escalate into claims and disputes.
- Risk assessments become little more than exercises in self-protection, rather than being genuinely useful tools for managing uncertainty.
If we could just get a better balance in the way we share out risks, with clients taking on truly unmanageable risks and contractors getting the risks that they’re actually able to manage, that would probably bring down overall outturn costs. In fact, pilot contracts that have used alliancing models have shown that this approach can actually reduce cost variability, even if the headline tender prices do seem a bit higher at the outset. And as for the increased risk that does come with adversarial approaches, that’s ultimately borne by the taxpayer.
8. Design Standards, Over-Specification and “Gold-Plating”
The design standards for highways, rail, bridges and stations in the UK have evolved over time, often in response to specific incidents or inquiries. The result is a default approach that’s unnecessarily conservative and applied uniformly across a wide range of different contexts.
We see plenty of examples of this. The HS2 Phase 1 viaducts were initially designed with extra structural margins that were actually wider than European norms. It was only through benchmarking exercises that we were able to identify and partially correct that discrepancy. UK stations end up with all sorts of intensive mechanical and electrical systems, complex passenger flow modelling and high architectural specifications, all of which add up to costs that are about 50% higher than comparable stations in Spain. Building services infrastructure includes HVAC, plumbing, and electrical systems, all of which contribute to the premium when you over-specify things.
Safety, of course, has to remain the top priority. But using blanket application of worst-case standards, rather than doing a risk-based, context-specific design, just adds unnecessary steel, concrete and systems costs, especially in low-risk environments. Assets that are classified as critical infrastructure get treated the same way whether they’re serving a rural branch line or a major intercity route.
If we were to update our guidance to allow for performance-based design and to make better use of digital modelling, civil engineers would be able to optimise structures and align standards with actual risk and usage profiles, without compromising the safety outcomes that really matter.
9. The Hidden Cost of Interfaces and Fragmented Design Responsibility
When you split design responsibilities across multiple different organisations, you end up with a whole lot of high-risk interfaces. One consultant handles the civils, another handles the systems, a third designs the stations and separate contractors deliver the earthworks services. Each one works to its own programme, its own assumptions and its own software platforms.
Misaligned BIM models, late design changes and conflicting technical specifications between disciplines causes reworks, programme delays and increased claims during construction. Crossrail provided a telling case study: delays at stations like Bond Street reflected the coordination challenges between multiple disciplines and contractors, with signalling and software integration between new tunnels and existing infrastructure proving particular trouble spots.
Getting off on the right foot is key : using a single, multidisciplinary team to lead design early on, with constructor input from day one, appears to reduce uncertainty and gets you more buildable, cost-effective solutions. When services infrastructure is well integrated, you see lower operating costs – by up to 26% in some cases , and that’s just one example of the value of getting integration right from the start.
The CMA’s 2026 work recommended more use of integrated alliancing or long-term frameworks to tackle this problem on road and rail projects. You can be pretty sure the sector will take note of that.
10. Labour, Skills and Productivity in the UK Construction Industry
The UK construction industry has a long history of struggling with slow measured productivity growth compared to some of its European neighbours. Limited adoption of industrialised methods, a high reliance on subcontract labour and fragmented supply chains all contribute.
Skills shortages have piled on the problem over time. Take the 2008 financial crisis, for example – it drove experienced workers right out of the sector and they never came back. Then there was Brexit related changes to migration from 2016 onwards, which reduced availability of specialist foreign labour further. And of course there was the COVID-19 pandemic, which disrupted training pipelines and site operations.
When skilled resource is in short supply you tend to pay a premium for key disciplines like tunnelling crews, complex earthworks teams and high-integrity paving specialists – which drives up project budgets. Meanwhile competitors in EU countries such as Spain and Germany are using more industrialised construction methods, modular components and off-site prefabrication. Britain has been slow to follow their lead.
Sustained investment in apprenticeships, modern construction training centres and long-term pipelines of work are essential to raise productivity and reduce costs over time. The idea of phased development is a good one : letting you create modular, scalable infrastructure projects. However this approach requires one important thing – the certainty of ongoing programmes.
11. Material Costs, Supply Chains and Market Structure
While global markets set baseline prices for cement, steel and aggregates, UK specific factors push prices higher. Planning constraints on quarries limit aggregate supply. And domestic cement production capacity is limited too. Logistics bottlenecks and the island geography of Great Britain add to transport costs.
Certain specialist sectors present particular challenges. Railway electrification components and high-end signalling are dominated by a handful of global suppliers, limiting competitive pressure in British tenders. Digital connectivity, including broadband networks and telecommunications systems, relies on similar concentrated supplier bases for specialist equipment.
Years of episodic investment have discouraged manufacturers from setting up shop in the UK. When demand surges, as it did for HS2 and network upgrades, capacity bottlenecks push up lead times and premiums. But when demand falls investment in domestic capacity becomes unviable.
Better signalling of programmes for critical infrastructure renewal might give suppliers the confidence to invest in UK facilities. This would support both supply chain resilience and cost reduction across the sector.
12. Climate Change, Resilience and the Cost of Future-Proofing
Though it may seem far off, there’s hard evidence that projections of hotter summers, more intense rainfall and sea-level rise are already shaping the design of roads, railways, drainage networks and coastal defences across the UK. Rail transport costs related to extreme weather events could rise to £500 million annually by the 2040s, making resilient infrastructure a necessity rather than a luxury.
Higher resilience requirements mean we have to add things like deeper drainage systems, larger culverts, stronger embankments and more robust retaining structures. These all add significant capital cost upfront. But then there’s the added benefit of building something that’ll actually last : designing for resilience upfront is cheaper than retrofitting later.
13. Decarbonisation, Electricity Generation and Network Upgrades
The UK’s statutory net-zero targets, together with the growth of offshore wind, solar and battery storage since around 2015, have driven a large programme of grid reinforcement and new electricity generation connections. Sustainable infrastructure includes renewable energy power plants, and connecting these remote renewable energy sources to demand centres requires major new transmission lines, substations and marine cables.
A lot of these energy infrastructure projects will face similar challenges to those in the transport sector. They also require the same specialist contractors, materials and civil engineers as traditional transport upgrades. And in another coincidence, sustainable transportation reduces reliance on greenhouse gas-emitting cars but delivering the electrified networks and charging infrastructure to support it demands the same scarce civil engineering resources
Co-ordinated Planning of Energy and Transport Infrastructure: Cutting Red Tape
Planning out the best way to use our shared corridors and infrastructure can make a big difference. By avoiding duplication of work and reducing the disruption that comes with it, we can save time and money. Smart building tech has already shown us the way – it can make a building up to 34% more energy efficient. And that’s just the tip of the iceberg – integrating building services with wider energy infrastructure can deliver some really tangible efficiency gains.
14. Urban Complexity: Building Under and Around Existing Cities – A Very British Problem
You know the cities that are driving our megaproject spending? London, Birmingham and Manchester are the ones that throw up the biggest challenges – all those underground services, heritage buildings, third party property issues and live rail operations. And it’s no surprise – robust infrastructure is the backbone of a thriving city, but getting it in place under all those existing buildings and roads is a real challenge, and a very expensive one.
Crossrail, Thameslink and all those other big projects show just how tough it is to work under live rail lines and on top of existing buildings. Night time working, restricted access, possessions of live rail lines and all that noise control stuff just adds to the costs, and lets be honest, puts a whole lot of strain on the construction team.
It’s the same story elsewhere in the world. The difference is that some countries are good at learning from their mistakes, and applying those lessons on their next project. They’ve got a steady stream of urban metro and rail projects, and that helps them cut costs and build up institutional knowledge. Not so here – we do a few big projects, and then leave them to gather dust for years.
15. Maintenance Backlogs and the Cost of Catch-Up
All that under investment in routine maintenance over the years has left us with a big maintenance backlog on roads, bridges and rail. And now we’re forced to take on major renewal and upgrade projects – that’s a whole lot more expensive than keeping things in good nick in the first place.
Just think about it – if we’d done some routine resurfacing and drainage work on our highways when we should have, we wouldn’t be facing full depth reconstruction now. And that’s a whole lot more expensive than the original work would have been. Same story with civil assets – getting it right first time saves a whole lot of money in the long run.
And then there’s the rail assets – oh boy, it’s a mess. The embankments, cuttings and drainage systems that have been in place since the 19th century are a major challenge when you’ve got modern traffic loads and climate change to worry about. Putting off maintenance for the sake of short term savings just means we’ve got a bigger bill to pay down the line. And that deficit just keeps on growing.
16. How Current Procurement Practice Undermines Innovation and Productivity
You know how we tend to go for short term lowest price tenders? Well, that discourages contractors from investing in new tech that could actually save us money in the long run – think off-site manufacturing, digital twins, advanced surveying and modern plants.
But there are examples out there of innovation that could really cut down on whole life costs – like modular bridge spans and precast track slabs, automated compaction control in earthworks, and digital twin technology for predictive maintenance. But these things are not being adopted very widely.
The CMA’s 2026 investigation showed that our fragmented frameworks and constant competition for similar work packages just pushes firms to focus on bidding rather than research and development. The construction industry spends less on R&D than most other sectors. But it doesn’t have to be that way.
Outcome based, multi-year frameworks with shared savings mechanisms would give the supply chain the incentive to bring forward some really innovative, cost saving ideas. Just think about it – if we could apply the same level of energy efficiency to our construction projects that we see in other sectors, that would be a game changer.
17. Towards More Cost-Effective Delivery Models
You know those programme level alliances that we’ve been trying out on some of our rail and water projects? Well, they’ve shown some real promise in terms of cutting costs and time – and they get the client, designers, and constructors all working together towards the same goals.
And have you ever thought about how much sense it makes for us all to work together from the very start of a project? Getting contractors and operators involved from the beginning can help us come up with some really practical solutions for earthworks, structures and paving layouts. Problems get identified when they’re cheap to fix, not on the site when they’re expensive. This approach recognises that infrastructure development is always best done as a collaborative process.
Outcome based specifications show what we need in terms of performance – like availability, resilience and whole life cost – rather than trying to dictate every technical detail. That gives the supply chain the freedom to come up with some really innovative solutions – and if we can share performance data across all our programmes, that will help us keep improving and benchmark ourselves against the best in the world.
Why Experienced Infrastructure Engineering Matters
A lot of the problems discussed here come back to the same basic point: infrastructure gets expensive when decisions are made too late, responsibilities are fragmented and practical engineering input arrives after the big choices have already been made. Good infrastructure engineering is not simply about producing drawings once a scheme has been decided. It is about looking at how a project will actually be built, where the risks are likely to appear and whether there is a more sensible way of delivering it before unnecessary cost gets baked in.
That is where experienced multidisciplinary teams can make a real difference. MAC Group Ltd infrastructure services cover the planning, design and delivery of infrastructure works, bringing together the technical knowledge needed to deal with highways, drainage, earthworks, utilities and wider development requirements. Having that expertise involved early gives developers and project teams a much better chance of spotting conflicts, challenging over-complicated solutions and designing infrastructure around what the site genuinely needs.
None of that solves Britain’s wider procurement and funding problems on its own, of course. But at individual project level, better coordination and stronger engineering judgement can remove a surprising amount of avoidable cost. When infrastructure is designed with construction, maintenance and whole-life performance in mind from the beginning, there is simply less room for the redesigns, delays and expensive surprises that have become such a familiar feature of UK projects.
18. Strategic Planning, Spatial Frameworks and Joined-Up Investment
It’s fair to say that our patchwork of local plans and sector specific strategies doesn’t really give us an integrated view of housing, transport, energy and water needs at the regional scale. Infrastructure planning needs to be about balancing current demands with future needs – but it’s all too often done project by project, rather than looking at the bigger picture. And who’s in charge of making these decisions? Well, it’s usually whoever happens to be in power at the time, rather than whoever will be making the decisions in years to come.National Infrastructure Strategies and Emerging Spatial Development Frameworks can get critical infrastructure corridors lined up properly, sort out duplication and make better use of land. With some good strategic planning, you can get lots of different projects all bundled together into one delivery programme, which can make a big saving on getting things started and handling all the traffic management.
Strategic placement of infrastructure can prevent that messy urban sprawl that just seems to happen, while using data to inform the planning process, along with Geographic Information Systems and looking at demographic trends, can make sure you’re investing in the places that will get the most bang for your buck.
Schools, hospitals, public spaces and the services that support them – all can benefit from the same coordinated approach. By getting public transport right, you can help urban areas stay compact and efficient. And, by taking an inclusive approach to planning infrastructure, you can make sure that everyone’s needs are met, including those in underserved areas who might be struggling to get access to the services they need.
Building infrastructure that can grow with the population, and planning for the next 30-50 years, is key. And, of course, that planning needs to take account of climate change, as well as the life of the assets we’re creating – rather than just being driven by short-term electoral cycles.
Policy makers in Northern Ireland, Scotland, Wales and England would all benefit from making some stable, long-term commitments to infrastructure investment that would outlast the current parliamentary term. And let’s be honest, economic stability is going to depend on just that.
19. Designing for Sustainability: Green Roofs, Blue Green Infrastructure and Beyond
Urban planning these days is all about incorporating eco-friendly technologies into transport and building projects. So, sustainable drainage systems, tree planting, and green roofs on stations, depots and administrative buildings are all part of a bigger picture where the infrastructure is seen as part of the environment rather than separate. And that’s what green infrastructure is all about – it captures or slows down rainwater.
Green roofs do all sorts of good things: they reduce stormwater runoff and improve air quality. And, when green roofs are used on service buildings or noise barriers, they add extra waterproofing life, cut down on cooling costs and contribute to meeting biodiversity targets. The upfront cost is not that much higher, but the benefits last the whole lifetime of the project – reduced stormwater runoff, lower cooling bills, extended roof membrane life and all the benefits that come with a greener environment.
Sustainable water infrastructure is all about making sure everyone has access to clean drinking water – and that’s the same for surface water management; filtering out silt and pollutants before the water gets to the drains or waterways. Low-carbon paving – using recycled materials, warm mix bitumen and permeable surfaces – might cost a bit more at first but it saves on embedded carbon, helps reduce the urban heat island effect and can lower maintenance costs over time. It’s all about using materials that can be renewed, reused and recycled – which aligns perfectly with whole-life value engineering.
The thing is, real sustainability needs a proper lifecycle costing tool that captures all those benefits. Lowest-price tendering on day one goes against all that – it actively discourages adopting approaches that reduce stormwater runoff, improve energy efficiency and save on maintenance over decades. All that upfront investment is lost when the focus is just on the upfront cost.
20. The Role of Civil Engineers in Bringing Costs Down
Experienced civil engineers in the UK are in a great position to challenge over-complex designs, rationalise routes, make the most of earthworks services and specify durable yet cost-effective paving and structures. They really need to be brought in at the earliest stage of policy and investment decisions, not just when the design is being finalised. When you factor in practicality and whole-life costs from the beginning, you get choices that can cut costs – like aligning routes that reduce tunnelling, designing stations that are less complex, and paving that’s right for traffic load and climate.
If engineers can develop the skills to think about systems, understand the commercial side and engage effectively with stakeholders, they can really influence the procurement models and governance structures. That means they can produce more than just technical drawings – they can actually help create solutions that are safe and efficient – and bring costs down in the process.
Getting strong technical capacity in place in client organisations is what the World Bank and other international bodies consistently say is key to making infrastructure delivery more cost-effective.
Civil engineers need to stick to their professional standards, and be independent, so they can give advice on value for money and resist over-specification. Bringing costs down is not about cutting corners, but about using expertise to get the best possible results.
21. What Needs to Change for Britain to Build Better, Not Just Cheaper
Britain’s high infrastructure costs aren’t because of individual project failures, but because of deep-seated issues with procurement, governance and risk allocation that have built up over 40 years. The same problems show up over and over again in roads, railways, stations and energy networks – fragmented contracts, short-term funding, transferring risks in a way that’s not collaborative, over-specification and weak strategic planning all combine to produce results that neither the government nor the construction industry are happy with.
The CMA’s 2026 findings are a clear call to action. Britain needs to move from fragmented, short-term procurement to long-term, collaborative, outcome-based models. That would support innovation, reduce waste and allow the sector to invest in its people and technology. The potential savings of up to £5 billion per year are not just pie in the sky – they reflect the gap between current practice and what reformed procurement could deliver.Stable Infrastructures pipelines, smarter planning, a more realistic split of risk and standards that take the context into consideration can all help drive down costs while still delivering safe, resilient infrastructure as we tackle the challenges of climate change. The long term economic health of the country really does depend on getting this right. Every pound squandered on pointless bureaucracy, duplicated overheads or petty squabbles between companies is a pound not spent on the basic services, transport links and energy networks that actually make economies tick.
If the UK is willing to tackle these deep-seated issues, then there’s no reason in the world why it can’t match or even outperform its peers when it comes to the quality and affordability of its critical national infrastructure. The evidence is stark, the question is whether the politicians have the will to take action on it.
Frequently Asked Questions
Why on earth do UK infrastructure projects take for ever to get off the ground?
The main reason is the consenting process is a total nightmare. Major rail and highway schemes need Development Consent Orders or hybrid Bills, which means an enormous amount of time is spent on environmental assessments, chasing up multiple stakeholders and dealing with an endless stream of regulators. Each layer adds more time and the submissions are getting out of control – some DCO applications are now running to 90,000 pages.
The opportunities for people to block the project through judicial review don’t help either. Companies are over- specifying their assessments to try and avoid any potential challenges, but this actually ends up extending the whole process even further. Between 2012 and 2021, the average decision time for DCO applications actually went up by a whopping 65%. We could sort this out by introducing clearer national policy statements, funding better resourced planning departments and actually getting real community engagement happening from the start. This could all be done without sacrificing any of the environmental protections we need.
Are UK safety and environmental standards the main reason why our infrastructure projects are so much more expensive than they are in Europe?
Safety and environmental standards contribute, but they aren’t the root cause. France, Germany, Spain and the Netherlands all have exactly the same standards, yet they still manage to build transport and energy infrastructure more cheaply. The difference is all about how they do the procurement, planning, funding and delivery of these projects. Countries with a steady pipeline of similar work can really benefit from the economies of scale and the construction companies can invest in more efficient methods, new materials and modern construction techniques.
Would it just be easier to cut standards or cut down on public consultation to make UK infrastructure cheaper?
No, it wouldn’t be a good idea to cut standards or consultation just to save a bit of cash upfront. If you do that, you’re just storing up problems for the future – you’ll have to put even more money into fixing everything that goes wrong. Leisure centres, hospitals and schools all need these environmental controls to stay safe. We should be getting rid of all the unnecessary duplication in the assessment process, making sure our designs are as efficient as possible through performance-based standards and sharing the risk more fairly between the client and the contractor.
How can local authorities influence the cost of infrastructure projects if most big projects are national schemes?
Local authorities play a much bigger role than people often give them credit for. Councils that get their local plans sorted, coordinate utility diversions, protect development corridors and get in early with the companies behind the project can cut down on land risk, objections and redesigns that otherwise add time and cost to the project. They’ve got knowledge of the local area that is just invaluable. When local authorities and the national companies get together early and work in a constructive way, you get much better outcomes than when they get together at the last minute and start arguing.
What practical steps can be taken now to make UK projects more cost effective?
There are loads of things that can be done right now to make our projects more cost effective without needing to change the law:
- Adopt long-term procurement frameworks that span multiple projects and funding periods.
- Get contractors and designers in on the project right from the beginning using formal early contractor involvement processes.
- Use standard components for things like bridges, retaining walls and station elements where possible, and have them made off-site.
- Invest in digital design tools, including BIM and digital twins, to cut down on rework and make sure everything is coordinated properly.
- Get funding sorted so that companies can invest in new plants, skills and innovation with some confidence.
- Apply standards that take into account the actual context of the project rather than just adopting the most extreme scenario.
These steps would all start to close the gap between our infrastructure costs and what our international peers achieve, without compromising on safety or quality in the slightest.
