According to the CPA’s Autumn Forecasts, construction output is expected to fall by 6.8% in 2023, similar to the 7.0% contraction forecast three months ago, before a further marginal fall of 0.3% in 2024.

This is a revision down from the 0.7% growth forecast in the Summer publication due to a weaker economic backdrop.

Although UK interest rates are now likely to have reached a peak that is lower than previous expectations, it is now anticipated that they will remain at this level for longer, until 2025, due to stubborn inflation.

Consequently, the UK economy is expected to flatline throughout 2024, holding back the recovery in major sectors of construction activity such as new build housing and repair, maintenance and improvement (rm&i) to 2025. 

Even in infrastructure, output is now expected to fall marginally as more roads projects appear likely to be pushed back or cancelled than anticipated only three months ago. Nevertheless, activity will remain near the current high levels due to work continuing on major projects already down on the ground.

Private housing is both the largest construction sector and the sector forecast to be the worst affected by prevailing economic conditions this year. The sharp increase in mortgage rates since the end of last year has led to house builders reporting a 30-40% fall in demand and it has remained weak throughout Summer and early Autumn. Interest rates and mortgage rates are expected to remain high for longer and adversely affect demand throughout next year.

As a result, after a 19.0% fall in completions and output this year, completions are forecast to remain flat in 2024 with no growth until 2025. While the balance of risks to private housing clearly remains on the downside, a positive policy stimulus in the Chancellor’s Autumn Statement would help demand to start to recover next year.

Private housing rm&i is the second-largest construction sector and activity continues to be on a general downward trend after the ‘race for space’ spike between 2020 and 2022. Output is forecast to fall 11.0% this year.

As with new build housing, the weak economic backdrop in 2024 will limit the pace of recovery, with a weaker housing market reducing transactions-related improvements and a notable fall in new planning applications for larger improvements work.

This will keep construction output flat in 2024, which is a downgrade from the 2.0% growth expected in the Summer Forecasts. Energy-efficiency retrofit – primarily insulation and solar photovoltaic work – continues to remain strong; however, while there are government programmes such as ECO4, the Great British Insulation Scheme, and the Boiler Upgrade Scheme in place, there are still questions over their delivery.

In the third-largest sector, infrastructure activity remains strong down on the ground due to work continuing on major projects, such as HS2 between Old Oak Common and Birmingham, the Thames Tideway Tunnel, and Hinkley Point C.

Unfortunately however, following on from earlier announcements of delays to major road and rail schemes, it appears that more roads projects are being pushed back or cancelled than anticipated in the forecasts in Summer, while new projects continue to be delayed due to strong cost escalation and viability concerns.

The impact of the government’s decision to cancel HS2 between Birmingham and Manchester is limited as the majority of this work was planned to occur beyond the forecast period. Similarly, the £36 billion of local and regional projects around the country announced by the Prime Minister are unlikely to start before 2029, at the earliest, if they occur at all.

Overall, infrastructure output is expected to fall by 0.5% in 2023, from its current high level, before remaining broadly flat (-0.1%) in 2024.

Commenting on the Autumn Forecasts, Rebecca Larkin, CPA Head of Construction Research, said: “With only a couple of months left in a difficult year for construction and looking forward to 2024, the evidence suggests it will still be a while before the clouds begin to lift.

“Both new build housing and rm&i have taken a significant hit from rising interest rates, falling real wages and weak economic growth. Although further rises in interest rates now appear off the table, the prospect of rising oil prices keeping inflation elevated suggests rates are likely to remain at peak for longer and throughout next year.

“This will keep demand subdued for house purchases and improvements. It will also create a step-change in financing costs compared to the record-low rates of the past decade for new commercial and industrial projects that is likely to limit appetite for investment and development.

“With infrastructure now set for two years of flatlining activity, it does shine a light on the importance of major projects as a driver of growth in the sector and for construction overall.

“In particular, government’s chopping and changing on infrastructure spending decisions this year has removed roads, rail and offshore wind projects from the near-term pipeline and has further weakened the industry’s confidence that government announcements can translate into tangible delivery.”
