With demand in the sector continuing to contract, overall output is expected to fall by 5.5% in 2024, compared with 2023.
The expected decline is mainly a result of decreased output in the housing, private commercial and industrial sectors, according to the BCIS analysis.
Growth is expected to return in 2025, with total new work output increasing 20% by the second quarter of 2029.
BCIS chief economist David Crosthwaite said: “As long as the cost of borrowing remains elevated, construction output is likely to suffer continuing declines. This is especially the case in the private sector, because it’s a major barrier to investment. We've also seen the pipeline for new orders affected by the stagnant economy.
“However, with strong cross-sector wage growth, albeit to a lesser extent in construction, any expectations that we’ll see the first cut to the base rate this month have largely fallen away, and we’re now looking at August as the earliest date.
“Construction activity will of course be influenced by the outcome of the general election and future spending plans, though all parties have committed to new increased housebuilding and using infrastructure as a lever for growth.”
The BCIS All-in Tender Price Index, which measures the trend of contractors' pricing levels in accepted tenders (i.e. the cost to client at commit to build) saw annual growth of 2.3% in the second quarter of 2024.
Dr Crosthwaite said: “The BCIS TPI panel has reported that contractors remain risk-averse and selective about the projects they bid on. We expect annual growth in tender prices to continues to fall, but for them to be rising faster than costs by this time next year.”
On the input costs side, labour remains the main driver, though annual growth in the BCIS Labour Cost Index is forecast to slow, increasing overall by 17% between Q2 2024 and Q2 2029.
Annual growth in the BCIS Materials Cost Index has been in negative territory for the past two quarters and is expected to show a further 1% drop for Q2 2024. There was a slight uptick in Q1 2024 compared with the previous quarter and BCIS expects the index to increase by 14% over the next five years.
Dr Crosthwaite added: “The upside risk to labour costs is that wages are driven up by widely reported skills shortages, which could impact on the viability and affordability of projects. The workforce is 90% what it was before the pandemic, when there were already long-standing concerns about fulfilling skill requirements.
“With materials, there remains an ongoing risk to price inflation due to uncertainty around disruption to trade routes in the Red Sea and conflict in the Middle East and Ukraine.”
