April has brought one of the clearest signals so far in 2026 that geopolitical pressures are now feeding directly into UK construction activity.
Two major housebuilders have issued stark updates within weeks of each other.
Berkeley has halted new land buying and frozen hiring while Crest Nicholson has warned it may not make a profit this year, with its share price falling by more than 30%.
Both companies pointed explicitly to the same underlying issue: the impact of the Iran conflict on inflation, interest rate expectations and buyer confidence.
Housing: developer confidence weakens further
The scale of the response from housebuilders is significant.
Berkeley has confirmed it will slow build-out rates, reduce subcontractor use and stop acquiring new land, citing weak demand, rising costs and increasing regulatory pressure. Crest Nicholson has gone further, warning that it may break even or even post a loss this year, compared with earlier expectations of around £35 million in pre-tax profit.
In both cases, the land market has become a central concern. Crest described it as effectively “paralysed”, while Berkeley stated that new land acquisitions no longer deliver acceptable returns under current conditions.
Geopolitical pressure: costs and confidence shifting
The impact of the Iran conflict is now feeding through into the construction market in two key ways.
First, rising energy and fuel costs are increasing the cost of materials, transport and site activity. Second, expectations for interest rate cuts have weakened, pushing mortgage rates above 5% and reducing buyer confidence.
Insolvencies: pressure building rather than easing
Further evidence of ongoing strain across the sector came this month from Construction News reporting on rising insolvencies.
More than 300 construction companies entered insolvency in February 2026, with 301 firms affected — a 9% increase on January.
Over the past 12 months, a total of 3,851 construction companies have become insolvent, with the sector continuing to account for around 17% of all UK insolvencies.
Industry sentiment: PMI remains weak, but expectations improve
The March 2026 UK Construction PMI, released in early April, came in at 44.5, confirming continued contraction across the sector.
Housing remains the weakest segment, while civil engineering is showing a slower rate of decline.
More notably, forward-looking sentiment has improved again, with confidence reaching its highest level since late 2024. Firms increasingly expect output to rise over the next twelve months, despite current workloads remaining subdued..
Materials demand: prolonged downturn continues
The latest Mineral Products Association (MPA) briefing confirms that construction demand has now declined for four consecutive years, with aggregates and concrete volumes still below long-term levels.
This highlights the disconnect between sentiment and activity. While expectations are improving, the materials data shows that physical output has yet to recover, particularly in housing-led segments.
Infrastructure remains the most likely source of future demand growth, with public sector and energy-related projects expected to play a central role.
Final thoughts from Leading Edge
April marks an important shift in the construction cycle. The sector remains under pressure, but the nature of that pressure is changing.
The data and industry updates point to a market that is:
- Still operating below trend
- Heavily constrained by housing weakness
- Increasingly influenced by global economic conditions
- Showing early signs of stabilisation
- Becoming more cautious in forward planning
For manufacturers and suppliers, this is a more complex environment than a straightforward downturn or recovery. Demand is stabilising, but decision-making is becoming more sensitive to both cost pressures and external risk.
At Leading Edge, our work across construction markets continues to show that this is where competitive advantage is built — not during periods of growth, but during periods of adjustment.
