The Office for National Statistics (ONS) publishes monthly estimates of the amount of construction output chargeable to customers for building and civil engineering work in Great Britain, split by sector and type of work(1).
Construction output edged up in 3Q2025
Construction output increased by just 0.1% between the second and third quarters of the year, representing an annual increase of 1.5%.
New work fared less well than repair and maintenance (R&M) on a quarterly basis – output was down by 0.2%, although the annual increase in all new work output was 1.8%. All R&M output was up by 0.6% compared with the previous quarter and by 1.0% on the year.
The greatest quarterly increases were seen in public other new work, which includes health and education projects (4.5%) and private housing R&M (2.9%).
| Sector | Change 3Q2025 compared with | |
| 2Q2025 | 3Q2024 | |
| New work | ||
| Public housing | 1.0% | -16.3% |
| Private housing | -1.9% | 2.4% |
| Infrastructure | -1.5% | 3.0% |
| Public other | 4.5% | 22.5% |
| Private industrial | -1.6% | 20.7% |
| Private commercial | 1.7% | -8.0% |
| All new work | -0.2% | 1.8% |
| Repair and maintenance | ||
| Public housing | -3.5% | -9.1% |
| Private housing | 2.9% | 5.5% |
| Non-housing | -0.5% | -0.3% |
| All R&M | 0.6% | 1.0% |
| All work | 0.1% | 1.5% |
Construction’s 0.1% growth contributed to overall GDP also growing by just 0.1% in 3Q2025 – services increased by 0.2%, while production fell by 0.5%.
Dr David Crosthwaite, chief economist at BCIS, said: ‘With two weeks to go until the Autumn Budget, the latest output data are probably not what the Chancellor wanted to see.
‘Q3 is often the period for significant output growth, as the weather conditions are favourable for construction. This time, however, growth is lacklustre to say the least.’
On a monthly basis, September data show the highest level of new work output since October 2023 with an estimated £11.26 billion of work recorded, representing a 0.7% increase on August. The most significant increases by sector were in public other (3.6%) and private commercial (2.5%).
R&M output decreased overall by 0.5% compared with the previous month, with private housing R&M down by 1.7%.
