What the July 2025 survey measured
The S&P Global UK Construction Purchasing Managers’ Index (PMI) fell to 44.3 in July 2025, from 48.8 in June. The index uses 50 as the dividing line: a reading above it signals reported expansion, while one below it indicates contraction. The Construction Leadership Council’s August 2025 monthly update records the result and says it was the sharpest fall in construction activity since May 2020. This is a historical survey snapshot, not a measure of how much construction output the Office for National Statistics later recorded.
Housebuilding was the weakest part
The July update identified residential building as the main drag on the wider construction index. Civil engineering also weakened significantly; commercial construction declined more moderately. That mix matters: a single UK headline combines sectors with different clients, project pipelines and funding, so it cannot describe every builder or local housing market equally.
The PMI is based on monthly responses from construction businesses. It gives an early signal of changing conditions, rather than a census of completed homes, planning permissions or building-site output. A reading of 44.3 therefore should not be translated into a percentage fall in construction, nor treated as a count of homes that will be built or missed.
Orders, materials and staffing
Respondents reported that incoming work had fallen for a seventh consecutive month, with the decline at its strongest pace since February. They also described fewer tender opportunities. The July update noted that materials volumes were still decreasing, although at their softest rate since the start of 2025; supplier delivery times lengthened for the first time that year. Employment had fallen for seven months, while contractor use eased and contractor rates continued to rise. These indicators point to a difficult operating backdrop, but the survey alone cannot identify the cause of every firm’s experience.
Business confidence edged up from June’s low, even as companies remained concerned about the broader economy. That is not evidence that activity had already recovered. It records a small change in respondents’ expectations at that point in time.
What property readers should take from it
For developers, lenders and housing professionals, the July PMI was a warning about near-term demand and delivery conditions, particularly in residential construction. It was not a current forecast and should not be used on its own to assess a site, builder or borrowing decision. The original 2025 new-homes target discussed in contemporaneous coverage was a government ambition, not an outcome established by this survey. Later ONS construction statistics use different methods and should be checked separately when assessing actual output.
