Increasing mega programmes redefine the risk landscape
The United Kingdom’s construction market is contending with challenges at home and abroad - from domestic political uncertainty to the effects of conflict in the Middle East - amid a mixed economic backdrop.
The International Monetary Fund now projects modest growth of around 1.0% for the UK this year after earlier downgrades, yet recent monthly GDP figures have been stronger than expected. Even so, surging energy costs remain a key threat to construction prices – one that could worsen if global disruptions persist – demanding vigilance from clients on energy risk.

Cost escalation in the capital
London continues to dominate UK construction costs, even as other regions heat up. Our report shows that the capital is the UK’s most expensive place to build, averaging US$6,032.5 per m² - the fifth in our global ranking. This is forecast to increase by 3.5% in both 2026 and 2027, although prolonged energy price inflation could push these increases higher. In this context, the government is working to decouple and weaken the link between volatile gas prices from electricity costs – a move aimed at tempering energy-driven construction inflation and potentially bringing cost relief.
Insulation from shocks
The UK has learned from the disruption of recent years and is better prepared for shocks. Firms have stockpiled key materials like bricks and concrete blocks, which have helped to keep average lead times among the shortest globally, despite conflict-related disruptions.
One critical exception is structural steel. Amid government intervention in strategic industries, including plans to nationalise British Steel, 88.0% of our UK survey respondents still report steel delivery lead times of 9–12 weeks, at the slower end of global averages.
For UK clients, the implication is clear: cost certainty is becoming harder to secure, and contingency strategies will need to be built into every major scheme over the next 12–24 months.
Regional markets feel the heat
High-value investments outside London like data centres and gigafactories is fuelling cost pressures in other areas. As widely reported, Tata Group’s new battery venture Agratas is building the UK’s largest EV battery plant near Bristol, contributing to local construction cost inflation of 5.3% (with average costs now around US$4,093.5 per m²). Clients pursuing schemes in high-growth regional markets should therefore expect greater competition for labour and build this into programme and pricing assumptions early.
Meanwhile, in the Midlands, Birmingham’s multiple major regeneration schemes – including the £11 billion transformation of East Birmingham and the redevelopment of the former Smithfield market site – will continue to stretch local capacity and pushing construction cost inflation to roughly 4.0%, the highest in the UK. In markets like Birmingham, early contractor engagement is moving from best practice to necessity due to capacity constraints.
Heading north, Edinburgh (average build cost ~ US$3,989.5 per m²) presents a mixed picture: private-sector appetite has softened, but strong public investment is sustaining activity in key sectors such as education.
As a result, the cost gap between London and the regions is no longer widening in the way many investors expect, meaning location decisions based purely on historic cost assumptions risk being flawed.
High growth sectors need highly skilled labour
The boom in advanced industries is exacerbating Britain’s chronic skilled labour gap. Fast-growing sectors like data centres and life sciences are driving up demand for specialised trades faster than the workforce can adapt - and in our survey, 100% of UK respondents cited shortages of qualified MEP (mechanical, electrical and plumbing) workers. This means programme risk is now as much a function of labour availability as it is of design or procurement particularly for complex, MEP-heavy assets like data centres.
Another sector drawing on the limited pool of skilled labour is defence. With the UK government planning on increasing defence spending to 2.5% of GDP by 2027, the lively investment activity in this space means defence has emerged as one of the UK’s best performing sectors according to our survey. The long-anticipated defence investment plan is expected is to further bolster confidence and sustain growth in this space.
Leading the pack on AI
The UK is a front-runner in adopting digital innovations such as artificial intelligence to improve construction delivery. Digital tools in cost and project management are now the norm, giving firms a head start in integrating AI. Some 75.0% of UK respondents say AI capabilities are becoming increasingly important in client discussions and tenders.
Still, the industry’s fragmentation can slow widespread uptake. Strengthening cyber security which is the foremost challenge cited around construction AI, will be vital to capitalise on the country’s early momentum and drive productivity gains.
Sector competition
Residential development and corporate offices remain subdued, ranking only eighth and ninth in our national sector performance index. This is despite policy goals such as delivering 1.5 million new homes by the end of the current Parliament and an uptick in “return-to-office” demand.
Part of the challenge is that investors and contractors gravitate toward higher-margin projects in booming sectors like data centres, defence and life sciences, leaving housing and office projects lagging. For residential and commercial office developers, this creates a structural challenge: competing not just on price, but on attractiveness to a supply chain increasingly prioritising higher-margin sectors.
Real estate construction isn’t happening in a silo – it faces competition for resources from a £718 billion infrastructure pipeline tapping into the same pool of labour and materials. Overlapping project timelines across infrastructure and building sectors are straining capacity.
Despite proactive Government efforts to reform the planning system, the UK market still faces particularly challenging planning delays, negatively impacting market confidence and the viability of projects.
Navigating risk in the age of the billion-pound project
As UK programmes grow larger and more complex, risk is increasingly concentrated in single schemes. With inflation pushing more developments past the £1 billion mark, traditional procurement approaches are under strain.
Fixed-price contracts – especially those using two-stage tendering – leave contractors dangerously exposed to cost escalations, a weakness highlighted by recent high-profile insolvencies. Many firms now either factor in higher prices or avoid these high-risk bids altogether. Clients, in turn, are reluctant to shoulder full cost uncertainty, resulting in stalemates that impede progress. The challenge for clients is to stay attractive to contractors while protecting their own margins in such an uncertain climate.
The way forward lies in more transparent, collaborative approaches to risk-sharing. Key strategies include:
- Embrace a mindset of shared risk allocation – acknowledging the realities of today’s market and avoiding contracts that saddle contractors with all cost risk; traditional fixed-price contracting is increasingly misaligned with market reality clients who continue to rely on it risk reduced bidder appetite, higher pricing or project failure.
- Adopt collaborative contracting models that align incentives and share rewards, encouraging high performance across the supply chain.
- Engage contractors early to build trust and transparency, identify risks upfront and jointly plan mitigation before contracts are finalised.
- Leverage real project data to benchmarks against the wider market to set pragmatic cost and schedule targets – recognising that overly aggressive programmes can backfire by driving up risk.
- Stay flexible on procurement routes that to adapt as conditions change. Even if standard practices have not radically shifted after the recent Middle East turmoil, a more agile stance gives clients greater control in uncertain times.
As more of these £1 billion plus projects make it to market in the UK, clients’ who actively managing risk in partnership with their supply chain stand the best chance of delivering these ambitious programmes on time and on budget – in this environment, competitive advantage will come not from securing the lowest price, but from structuring projects in a way that the supply chain is willing and incentivised to deliver.
The rise of mega‑projects and shifting procurement models
The UK is experiencing a structural shift toward larger, more complex, multi‑year programmes, which is reshaping procurement behaviour.
Key points
- Scale and complexity are increasing across sectors, but scale does not equal efficiency; in fact, it often increases cost due to risk.
- Tier 1 contractors are increasingly unwilling to take on fixed‑price contracts for mega‑projects.
- This is driving clients toward:
- Two‑stage design and build
- Management contracting
- Construction management / PMC models
- These models balance risk with clients, improving deliverability.
