Today’s update: early 2026 data confirm a tough first quarter for UK construction, with site starts and PMI readings both pointing to ongoing contraction just as a £718bn infrastructure pipeline comes into sharper focus. At the same time, London tightens site rules and major clean energy and fusion projects move from strategy to delivery, reshaping opportunity even in a weak market. Here’s what you need to know to stay ahead today.
Ongoing Stories
Following earlier coverage of stresses in the UK’s multi-hundred-billion-pound pipeline, Glenigan’s Q1 2026 data now quantify a 17% quarterly drop in work starting on-site and a 30% annual fall in residential starts, underscoring how fast conditions have deteriorated against that long-term programme.

Returning to the theme of delivery risk on major programmes, the latest S&P Global UK Construction PMI shows March at 45.6, with housing activity especially weak at 38.2, signalling that the pressures highlighted by the ICE and others are being borne out in live workloads.

Continuing the clean energy infrastructure story, the approval of the 800MW Springwell Solar Farm and progress on hydrogen HAR1 projects confirm that the pipeline for utility-scale renewables is moving decisively from policy into pre-construction and delivery. (Sources: Electrek, Slaughter & May)
The STEP fusion scheme at West Burton, highlighted previously as a strategic risk–reward project, advances with £1.3bn of funding and a long-term construction partner now being procured ahead of a draft National Policy Statement on fusion expected this summer. (Source: gov.uk)

🏗️ UK construction starts slide 17% in Q1 as civils and housing stall
Glenigan data show UK construction work starting on-site fell 17% in Q1 2026 versus Q4 2025 and remains 18% below 2025 levels. Residential starts dropped 13% quarter-on-quarter and 30% year-on-year, while civils work plunged 37% on the quarter and 34% annually; non-residential work is 5% down year-on-year. The figures point to a broad-based slowdown that will hit contractors’ order books and could leave capacity underused just as the government seeks to accelerate delivery across housing, infrastructure and social assets.

🏗️ PMI shows construction in contraction for 15th month, with housing weakest
The S&P Global UK Construction PMI edged up to 45.6 in March from 44.5 in February 2026 but stayed below the 50.0 no-change mark for the 15th consecutive month. Housing activity remains the worst-performing segment with an index reading of 38.2, highlighting persistent weakness despite marginal overall improvement. This extended downturn in sentiment suggests pricing power will stay fragile and that residential-focused players, in particular, may need to recalibrate pipelines, capacity and risk exposure.

⚙️ Conflict-driven supply chain shocks push up fuel and material costs
UK construction is experiencing ongoing cost inflation, supply chain delays and new business challenges linked to disruptions in regional and global shipping routes following the Iran War that began in late February 2026. Higher fuel and materials prices are feeding through into tenders and live contracts, complicating cost forecasts and contingency planning. This raises the stakes for robust contract clauses on escalation and for careful timing of procurement and project starts in an already weak market. (Sources: Shareprices, Showhouse)
🏛️ New Westminster Construction Code tightens dust, noise and site approvals
From 9 April, a new Construction Code in Westminster introduces live dust monitoring requirements, stricter noise limits and a need to secure approval before work starts on-site. The code adds an extra compliance layer for contractors and developers in central London, particularly on complex or sensitive schemes. This will influence methods, programming and potentially costs on West End and central government projects, and may act as a template for other urban authorities considering tougher control regimes.

🚆 £718bn infrastructure pipeline and slimmed-down GMPP refocus delivery
The government’s March 2026 infrastructure pipeline identifies 734 planned projects worth £718bn over 10 years, prioritising hospitals, schools, rail, reservoirs and clean energy. From 1 April, the Government Major Projects Portfolio was narrowed from more than 200 schemes to around 80 high-priority projects to sharpen delivery focus. For the supply chain, this clarifies where central government attention and resources will concentrate, with major opportunities flagged around Gatwick’s £2.2bn Northern Runway, big data centres, offshore wind extensions and utilities upgrades starting from 2026.
