British house-building fell at the sharpest pace since May 2020 last month as the cost of higher interest rates outweighed an easing in supply chain difficulties that bolstered other types of construction, according to a survey released on Thursday.

The S&P Global/CIPS construction Purchasing Managers’ Index (PMI) fell to 50.7 in March after jumping to 54.6 in February, a bigger drop than the fall to 53.5 forecast in a Reuters poll of economists.

Even so, the reading still indicated modest growth and was the second-highest since October, when the “mini-budget” crisis under former Prime Minister Liz Truss’s government caused borrowing costs to leap.

“Despite worries about the near-term outlook for housing activity, expectations for total construction output during the year ahead were relatively upbeat in March,” said Tim Moore, economics director at S&P Global Market Intelligence.

Hiring rose at the fastest rate since October, reflecting greater workloads and new projects, and expectations for future activity were the highest since February 2022.

More broadly, the Purchasing Managers’ Index data published this week suggests Britain’s private sector avoided shrinking in the first quarter of 2023, after the economy as a whole eked out 0.1 per cent growth in the last quarter of 2022, according to official data.

The all-sector Purchasing Managers’ Index - which includes figures for the much larger services and manufacturing sectors, released earlier in the week - dropped to 52.1 in March from 53.2 in February but stayed above the 50 level which divides growth from contraction.

Construction accounts for about 6 per cent of British economic output, and the sector recorded quarterly growth of 1.3 per cent in the last three months of 2022.

The slowing of the construction PMI in March was driven by a fourth consecutive monthly fall in house-building, which declined at the fastest rate since May 2020.

Builders cited a reduction in new housing projects as a result of higher interest rates, S&P said.

Last month the Bank of England raised borrowing costs for the 11th time since December 2021, taking interest rates to 4.25 per cent. Mortgage lender Nationwide Building Society reported last month that average house prices in March were 3.1% lower than a year earlier, the biggest annual drop since 2009.

However, figures released earlier on Thursday by mortgage lender Halifax showed house prices in March were still 1.6% higher than a year earlier, after bucking economists’ forecasts for a month-on-month fall.
