UK Housing Market Braces for Slowdown as Iran War Drives Up Mortgage Rates

The UK housing market is currently navigating a volatile contradiction. While house prices saw a sharp spike in March, a wave of economic uncertainty triggered by the conflict in the Middle East is now cooling buyer sentiment and pushing borrowing costs to heights not seen in years.

For homeowners and prospective buyers, the geopolitical instability involving Iran has transitioned from a distant diplomatic concern to a direct financial burden, manifesting in surging energy costs and a rapid retreat of competitive mortgage products.

The March Paradox: Price Growth Amidst Instability

Despite the looming economic clouds, the UK property market showed surprising resilience in early 2026. According to data from Nationwide, the price of a typical UK home increased by 0.9% in March, marking the fastest growth rate in nearly 18 months. This surge pushed the average property cost to £277,186.

Annual house price growth also accelerated, jumping to 2.2% in March from 1% in February. However, analysts warn that this momentum is likely short-lived. The Guardian reports that while the March figures beat economists’ expectations of 0.6% growth, the “clouded outlook” caused by the US-Israel war on Iran is expected to put a significant brake on future activity.

The Mortgage Shock: Costs Climb as Lenders Retreat

The most immediate impact of the Middle East conflict is being felt in the mortgage market. Lenders have scrambled to adjust their pricing as expectations for the Bank of England’s monetary policy shifted abruptly.

The Shift in Interest Rate Expectations

Before the conflict began, financial markets anticipated that the Bank of England would cut interest rates twice this year. That outlook has been completely reversed. Because the war has sparked a surge in energy prices, markets now expect the Bank to raise rates to combat rising inflation. Specifically, some analysts expect the base rate to rise three times over the next 12 months from its current 3.75% level.

Rising Fixed-Rate Costs

This shift in expectations has led to a dramatic increase in the rates offered to consumers. Data from Moneyfacts, cited by Nationwide, reveals the scale of the jump since the start of March:

• Two-year fixed rates: Rose from 4.83% to 5.84%.
• Five-year fixed rates: Rose from 4.95% to 5.76%, the highest level since September 2023.

The real-world impact on monthly budgets is severe. For a typical £250,000 loan over 25 years, the average two-year fixed deal has added nearly £1,800 to annual costs, while five-year deals have increased by more than £1,400 since March began.

Dampened Demand and Regional Divergence

The combination of higher borrowing costs and energy price shocks is unnerving buyers. A survey by the Royal Institution of Chartered Surveyors (RICS), reported by Reuters and The Independent, highlights a noticeable cooling in the market.

Falling Enquiries and Sales

Buyer confidence weakened significantly in February. New buyer enquiries saw a net balance of 26% of property professionals reporting a fall, a sharp deterioration from the 15% recorded in January. Agreed sales also remained subdued, with a net balance of 12% of professionals noting a decrease.

Regional Variations

The impact is not uniform across the UK. RICS data shows a clear geographical split in price pressure:

• Downward Pressure: Strongest in London, the South East, and East Anglia.
• Firmer Trends: Northern Ireland, Scotland, and the North West of England continue to report more stable price trends.

Looking Ahead

While the immediate future looks bleak for buyer activity, some professional optimism remains for the long term. According to RICS, 17% of professionals expect sales to rebound over the next 12 months, and 33% believe house prices will eventually edge higher. However, for the present, the UK housing market remains a hostage to geopolitical volatility, with the cost of borrowing continuing to climb as the Middle East conflict persists.
