According to the report from IHS Markit/CIPS, September data revealed another growth slowdown in the construction sector, with output volumes rising to the smallest extent for eight months. This partly reflected softer demand conditions than the peak seen earlier in the summer. Survey respondents also cited disruptions on site from unavailable transport, a severe lack of materials and continued staff shortages. A rapid drop in sub-contractor availability was reported in September. Imbalanced demand and supply contributed to the steepest rise in sub-contractor charges since the survey began in April 1997. Some firms noted that the unpredictable pricing environment had slowed clients' decision-making on new orders and led to delays with contract awards.

At 52.6 in September, down from 55.2 in August, the headline seasonally adjusted UK Construction PMI Total Activity Index dropped further below the 24-year high seen in June (66.3). The latest reading signalled only a moderate expansion of total construction output and the weakest speed of recovery for eight months. Reports from survey respondents linked the slowdown to a combination of supply chain issues and softer demand.

All three broad categories of construction activity saw a loss of momentum in September, with the biggest slowdown seen in civil engineering (51.0, down from 54.8 in August). House building also decelerated in September, with the latest expansion the weakest since the recovery began in June 2020 (52.8). This left the commercial segment (53.6) as the best performing category during September. Resilience in this sub sector reflected a continued boost to order books from the reopening of the UK economy.

Meanwhile, the latest survey illustrated that construction firms remained highly upbeat about the business outlook. Just over half (51%) forecast rising output, while only 8% anticipate a decline. However, the degree of confidence was weaker than August amid some concerns that the supply chain crisis will hinder growth.
