LONDON, July 16, 2026 — The UK construction industry is facing another period of uncertainty after new data from the Office for National Statistics (ONS) showed that output declined in May 2026, with weakness in housing-related activity continuing to weigh heavily on the sector.
Although construction recorded modest growth over the latest three-month period, the latest figures highlight a fragile recovery rather than a broad-based rebound, with residential construction remaining one of the industry’s biggest challenges.
ONS Data Shows Uneven Construction Recovery
According to the Office for National Statistics’ Construction Output in Great Britain: May 2026 report, total construction output declined by 0.8% month-on-month in May 2026.
The fall followed a 0.1% decline in April, partially offset by stronger growth of 1.4% in March, reflecting the volatile conditions currently affecting UK construction activity.
The ONS reported that the decline was driven entirely by repair and maintenance activity, which fell by 2.1% during the month.
Meanwhile, new construction work provided some support, increasing by 0.2%.
The largest monthly weakness came from private housing repair and maintenance, which dropped by 5.0%, making it the biggest contributor to the overall decline.
However, the longer-term picture remains slightly more positive.
Construction output during the three months to May 2026 increased by 1.6%, representing the third consecutive period of three-month growth.
During this period:
- New work increased by 1.1%.
- Repair and maintenance activity grew by 2.1%.
- Seven of the industry’s nine sub-sectors recorded expansion.
Non-housing repair and maintenance was the strongest performer, increasing by 3.0%.
The figures suggest that the sector is not experiencing a complete downturn, but rather navigating an uneven recovery where certain markets are improving while housing continues to struggle.
Housing Remains the Biggest Challenge
The housing market continues to represent the weakest area of UK construction.
Private housing activity has been under pressure throughout 2026 as higher borrowing costs, affordability concerns and weaker buyer confidence continue to affect developers.
Private housebuilding has faced particular pressure, while public housing output has also recorded significant declines.
The weakness extends beyond new construction. Private housing repair and maintenance — traditionally a more stable source of contractor activity — experienced a sharp decline in May.
This indicates that households are also becoming more cautious about discretionary improvement and renovation spending.
Construction PMI Signals Continued Pressure
Independent survey data from the S&P Global UK Construction Purchasing Managers’ Index (PMI) reinforces the difficult conditions facing the industry.
The construction PMI remained below the 50-point threshold that separates growth from contraction, indicating continued pressure across parts of the sector.
Housing has been the weakest segment, while commercial construction has shown greater resilience compared with residential markets.
Companies surveyed have highlighted several challenges:
- High mortgage and financing costs.
- Reduced consumer confidence.
- Lower private investment.
- Rising operating costs.
- Uncertainty affecting project approvals.
The combination of these pressures has encouraged many firms to delay expansion plans and remain cautious about hiring.
Why UK Construction Is Losing Momentum
Several structural issues are affecting the pace of recovery.
Financing Costs Remain a Major Barrier
Higher interest rates have increased borrowing costs for developers, contractors and homeowners.
For housebuilders, this has reduced project viability and encouraged a more cautious approach to new developments.
Rising Costs Continue to Pressure Margins
Construction companies continue to manage elevated costs linked to:
- Energy.
- Fuel.
- Materials.
- Labour.
- Transport.
While some inflation pressures have eased, many contractors are still operating with tighter margins than before.
Planning Delays Slow New Development
Industry groups have repeatedly highlighted planning challenges as a factor limiting the speed at which new housing projects can move from approval to construction.
Delays can increase costs and make developments less financially attractive.
Implications for Infrastructure and Construction Suppliers
The current slowdown in housing does not affect only housebuilders.
A weaker residential market also impacts:
- Building material suppliers.
- Equipment manufacturers.
- Contractors.
- Specialist subcontractors.
- Construction technology providers.
Companies serving the UK construction market are increasingly looking towards infrastructure, energy transition projects and commercial developments for growth opportunities.
Outlook: Stabilisation Before Acceleration
There are signs that confidence may be improving gradually.
Government measures aimed at increasing housing delivery, improving planning processes and addressing construction skills shortages could support future growth.
However, the latest ONS figures suggest the industry remains in a stabilisation phase rather than a strong expansion cycle.
For the construction sector to return to sustained growth, housing demand will likely need to improve, financing conditions will need to become more favourable, and developers will need greater confidence to restart delayed projects.
The challenge for 2026 is therefore not simply increasing construction activity — it is rebuilding the confidence required for companies to commit to long-term investment.
