The UK housebuilding sector is closely monitoring developments in the Middle East as efforts to end the ongoing conflict show signs of faltering. Following an initially positive start to the year, housebuilders have experienced a significant downturn in market activity amid rising geopolitical tensions.

Early in 2026, there were indications of recovery, including increased site visits from potential buyers and higher traffic on online property portals. However, the escalation of US military actions in the Middle East largely reversed these gains, according to Steve Turner, executive director of the Home Builders Federation. He described the initial optimism as having been “killed stone dead” by the events, underscoring the fragile state of the market.

The broader economic environment has also shifted significantly. Anthony Codling, an analyst at the Royal Bank of Canada, noted that the conflict “reset the macro backdrop,” leading to higher mortgage rates, the Bank of England shelving anticipated rate cuts, weakened consumer confidence, and an underwhelming spring selling season. These factors combined have resulted in a sharp stall in housebuilding activity.

Data from the first quarter reflects this downturn. Registrations for energy performance certificates—a commonly used industry proxy for completed homes—dropped to just over 48,000, the lowest level since the second quarter of 2020 during the COVID-19 lockdown. The higher borrowing costs are a key contributor: two-year fixed mortgage rates have increased by 0.8 percentage points compared to pre-conflict levels, according to the Bank of England.

This shift in financing costs is having a tangible effect on the housing market. UK house prices declined by 0.2% in the three months ending in May, marking the first quarterly fall in a year, according to Halifax data. The drop is attributed in part to the increased mortgage expenses dampening buyer demand.

Industry observers suggest that a resolution to the conflict could ease inflationary pressures, potentially allowing the Bank of England to resume interest rate cuts. Such a move would lower borrowing costs for developers and make mortgages more affordable for consumers. Howard Hawkins, an industry expert, noted that rates are unlikely to move downward unless inflation approaches the central bank’s target.

Turner expressed cautious hope that a peace deal could unlock “pent-up demand” in the market, improving consumer confidence and possibly stabilizing interest rates. However, he emphasized the sector’s guarded outlook, acknowledging the volatility of the current environment and the difficulty in forecasting future trends. “We’re probably prepared that the best-case scenario would be that rates stay where they are for the rest of the year,” he said, underscoring the uncertainty that continues to shape the UK housing market.
