At a Glance
UK construction activity contracted again in September, but at its slowest rate since January as the headline PMI edged up to 46.1.
Housebuilding remained the sharpest drag on the sector, while commercial and civil engineering work also declined and new orders fell at their fastest pace in three months.
Infrastructure and utilities starts jumped over 100% quarter-on-quarter, offsetting steep falls in residential and non-residential project starts.
The Building Safety Levy comes into force on 8 October, with lawyers warning it could materially affect scheme viability and land pricing.
Government is weighing legal reforms to curb judicial review challenges on Nationally Significant Infrastructure Projects, prompting caution from planning lawyers.
Today’s update: macro data and project-starts analysis point to a construction market still in contraction, with private housing and commercial work under heavy pressure while infrastructure and utilities carry much of the load. At the same time, fresh regulatory moves on building safety and NSIP legal challenges signal a tougher, more centralised framework for both developers and promoters of major schemes. Here’s what you need to know to stay ahead today.

Top 5 Headlines
💰 UK construction downturn eases, but September PMI shows ninth month of job losses
New S&P Global data put the UK Construction PMI at 46.1 in September, up from 44.3 in August and signalling the slowest contraction since January 2026, yet still below the 50.0 growth threshold. Housebuilding remained the weakest segment with a PMI of 40.7, commercial work hovered near contraction territory at 48.5, and civil engineering also declined. New orders fell at their fastest rate in three months amid delayed major project decisions, geopolitical concerns, higher borrowing costs and rising input prices, driving a ninth consecutive monthly fall in employment. Returning today to the broader pipeline concerns highlighted this week, the figures confirm a market that is softening rather than stabilising, with clear implications for bidding pipelines, staffing plans and subcontractor capacity.

🚆 Infrastructure and utilities starts surge 101% as housing and commercial projects stall
Infrastructure project starts rose by 130% and utilities by 73% in the three months to September 2026, driving a 101% quarter-on-quarter surge in these segments and leaving infrastructure starts 43% higher than a year ago. Despite this, total construction starts slipped 2% on the quarter and are still 18% down year-on-year, with residential starts falling 33% and non-residential 16%. The data underline a two-speed market where contractors and consultants with strong infrastructure exposure are better insulated, while housing- and commercial-led businesses face a thinner pipeline and greater competition for fewer viable schemes.

🏛️ Building Safety Levy takes effect on 8 October, raising viability questions
The Building Safety Levy, designed to fund improvements to development safety standards, becomes law on 8 October 2026. Legal advisers are warning that the levy could materially impact the financial viability of schemes and alter land transaction dynamics as parties re-price risk and adjust residual land values. For developers, investors and housebuilders, this introduces another cost line into already tight appraisals, increasing pressure on design value engineering, phasing and negotiations with landowners.

🏛️ Government eyes stricter limits on judicial review for NSIPs
Ministers are considering reforms to limit judicial review challenges for Nationally Significant Infrastructure Projects, potentially through a defined “challenge window” or by requiring parliamentary approval for certain actions. Some planning lawyers caution that these changes could themselves create new procedural complexity and delays, offsetting the intended streamlining. Returning today to the theme of stronger central intervention in planning, any shift in the challenge regime will be critical for promoters, funders and local authorities gaming out consent risk on large energy, transport and utilities schemes.

⚙️ UK Construction Week spotlights challenges amid £725bn long-term infrastructure ambitions
UK Construction Week ran from 29 September to 1 October at the NEC Birmingham, showcasing key industry trends and challenges across technology, skills, productivity and delivery models. In the background, government continues to reference a long-term infrastructure investment strategy of over £725bn in public funds over the next decade, based on analysis published earlier in 2026. The contrast between an ambitious public pipeline and current market softness reinforces the importance of capability, financing and regulatory clarity for those bidding and investing today for work that will land later in the decade.
