The downturn in UK housebuilding accelerated in August 2026, with residential activity falling sharply. The housing activity index, part of the latest S&P Global UK Construction PMI, dropped to 37.6, indicating a significant contraction below the 50.0 threshold that separates growth from decline.
This decline in housing activity was more pronounced than in other construction sectors, and it was the only major category to record a faster rate of decline compared to July. Commercial activity stood at 47.8, while civil engineering registered 40.5.
Survey respondents frequently cited subdued demand and a shortage of new projects, particularly in housebuilding starts. This weakness in residential development contributed to a challenging month for the broader construction sector, with the headline S&P Global UK Construction PMI falling from 44.7 in July to 44.3 in August, marking its twentieth consecutive month below the 50.0 growth threshold.
New orders also decreased, although this contraction was the weakest since September 2025. Firms attributed this to increased risk aversion following the Middle East conflict and delays in client decision-making. Construction employment continued to fall as companies struggled to secure new work, though the pace of job losses eased to its lowest level since February. Input costs continued to rise due to higher fuel, transport, and raw material prices, but overall input cost inflation eased to a six-month low.
