Estimates from the Office for National Statistics (ONS) suggest new work decreased by 0.2%, while repair and maintenance grew by 0.6%.

At the sector level, four out of the nine sectors grew in Quarter 3 2025. The main positive contributor to the increase was private housing repair and maintenance, which grew by 2.9%. The main negative contributor was private new housing, which fell by 1.9%.

The construction output growth in September followed a downwardly revised decrease of 0.5% in August 2025 and an upwardly revised increase of 0.2% in July 2025.

The increase in monthly output in September 2025 came solely from an increase in new work (0.7%), as repair and maintenance decreased by 0.5% on the month.

Total construction new orders grew by 9.8% (£1,078 million) in Quarter 3 2025 compared with Quarter 2 2025; this quarterly increase came mainly from private commercial new work and private industrial new work.

The annual rate of construction output price growth was 2.7% in the 12 months to September 2025.

Jo Streeten, managing director, Buildings & Places at AECOM: “A fourth consecutive rise in output shows an industry building momentum despite significant economic headwinds. The UK Government has set out its long-term vision for homes and infrastructure delivery but now we must see action on the ground. Ahead of the Chancellor’s Budget, the industry will be looking closely for stability and direction, not further roadblocks to delivery. 

“By accelerating delivery through digital planning tools, AI innovation and stronger public–private collaboration, policy can be turned into performance, ensuring every pound of investment achieves maximum impact.”

Clive Docwra, managing director of property and construction consultancy McBains, added: “Today’s figures will at least provide some degree of comfort ahead of what many expect to be a difficult winter for the construction industry.

“However, it’s still a mixed bag – while we welcome new work increasing by 0.7% in September and the private commercial sector witnessing growth over the month, performance over the last quarter as a whole remains sluggish, with new orders falling by 0.2% and private housing by a worrying 1.9%. It’s clear that underlying concerns from investors over the economy are still biting hard.

“The immediate road ahead remains challenging, and while many are expecting a lacklustre Budget later this month, the hope is that the Chancellor will make further commitments in terms of infrastructure investment and moves toward a more settled fiscal environment.  With housebuilding in need of a boost, reforms such as abolishing stamp duty would also provide a shot in the arm for the sector.”
