The UK infrastructure market enters 2026 with a cautiously optimistic outlook, supported by strong public-sector commitment, regulated investment cycles and long-term national priorities around decarbonisation, resilience, and connectivity.

Within civil infrastructure, inflation is generally seen as more stable through 2026–27, although cost pressure remains more pronounced in network-heavy areas (including utilities and power-related works) where supply chains and specialist labour can tighten quickly.

In rail, long-term confidence continues to be anchored by major programmes, including HS2, Northern Powerhouse Rail and East West Rail, alongside ongoing renewals, capacity improvements, and decarbonisation activity.

In roads, local authority and active travel schemes are helping to maintain workloads through smaller interventions, but procurement variability and budget constraints continue to influence pace and packaging.

Aviation is showing a stronger growth trajectory, supported by longer-term capital planning and a focus on digital upgrades and passenger experience, with several airport owners looking beyond short-term operational pressures towards a more sustained investment cycle.

Ports and Maritime are also positive, driven by freight volumes and modernisation requirements, alongside investment linked to the offshore wind and modernisation programmes.

Water remains a standout sector for workload and pipeline. With AMP8 investment exceeding £96bn (2025–2030), activity levels are high across resilience, wastewater, and digital water programmes. This creates a relatively secure pipeline, but it also heightens the importance of delivery capacity, sequencing, and supply chain readiness.

A consistent theme from clients and contractors is caution in decision-making. Work is progressing, but affordability is under sharper scrutiny, and schemes can still pause after early stages if approvals, funding gates or business cases slip. We’re also seeing a continued shift towards earlier engagement and more emphasis on delivery planning, cost-led design decisions, and scope certainty, as a response to the market’s reduced tolerance for avoidable change.

Risks and opportunities

The key risks continue to be skills shortages, procurement delays, and inflation volatility. Market feedback also highlights concern about geopolitical uncertainty and the knock-on impact on fuel and energy costs, which can disproportionately affect infrastructure delivery (particularly earthworks, logistics, aggregates and other plant-intensive activities). Where clients and contractors anticipate volatility, we expect a stronger push for clarity on inflation risk allocation, including increased use of fluctuation-type provisions or, alternatively, contractors pricing in wider risk allowances and exclusions.

Procurement remains a material lever. Single-stage, lowest-price competition can still produce fragile outcomes where scope maturity is limited or where risk is pushed down the supply chain without corresponding programme and information. In contrast, the stronger performing programmes are typically those that adopt early contractor involvement, clearer definition of employer risk, and commercial models that reward collaboration and realistic delivery planning.

Despite these risks, the opportunity set across UK infrastructure is compelling. Demand is growing for programme and project management office (PMO) capability, commercial and cost assurance, and digital support—particularly where clients are managing multiple workstreams, complex interfaces and regulatory requirements. There is also clear momentum around digital twins and data-led asset management, with digital increasingly moving from a “nice to have” to an operational necessity in regulated and operational environments.

Looking ahead through 2026, the market should remain resilient, where it is tied to decarbonisation, resilience, and regulated investment. The differentiator will be delivery: clients that plan for capability constraints, lock down scope earlier, and align procurement with market capacity will be best placed to convert strong pipelines into predictable outcomes on cost, programme, and quality.
