UK Construction Starts Drop 17% in Q1 as Iran Conflict and Weak Economy Hit Residential Work Hardest
What happened
Construction work starting on site in the UK fell by 17% in Q1 2026 compared to Q4 2025, finishing almost a fifth below 2025 levels, according to the latest Glenigan Construction Index.
Residential construction was hit hardest, with starts dropping 13% quarter-on-quarter and 30% year-on-year. Private housing was worse still — down 9% on the previous quarter but 34% below 2025 figures. Civils work plummeted 37% against Q4 and is now 34% below the previous year.
The only bright spot was offices, which rose 37% quarter-on-quarter — driven largely by a single £50 million development in the City of London. London was the stand-out region, with starts up 26% on Q4 and 69% above 2025 levels. The South West saw the worst performance, crashing 47% against Q4 and 54% below the previous year.
Glenigan cited the Iran conflict, rising material costs, spiralling energy prices, and a persistently weak economy as the main factors dragging down activity — particularly in residential construction, where developers and buyers are delaying decisions.
What this means for tradespeople
Fewer new builds and fewer large projects mean more competition for the domestic repair, maintenance, and improvement (RMI) work that keeps most self-employed tradespeople busy. When the pipeline shrinks, the tradespeople who stay visible to homeowners are the ones who keep working.
If you're a plumber, electrician, or builder in the South West or other struggling regions, you're likely already feeling this. Homeowners are still spending on repairs and improvements — but they're being more selective about who they hire. A strong Google presence with recent reviews makes the difference between getting the call and being overlooked.
The residential construction decline also means fewer subcontracting opportunities from developers. Tradespeople who've built a direct-to-homeowner pipeline through Google reviews and their own reputation are better insulated from these downturns than those relying on developer work.
What to do about it
Focus on building your direct-to-customer pipeline. When big projects dry up, it's the tradespeople with strong local reputations who stay busy. Fresh Google reviews are the single most effective way to stay visible to homeowners searching for trades in your area.
