The UK housing market experienced a notable slowdown over the summer months, driven primarily by elevated mortgage rates and ongoing economic uncertainty, new data indicates. According to property platform Zoopla, the number of sales agreed during the four weeks ending July 19 fell 9 percent compared with the same period last year, while house price growth slowed to 1.3 percent in June, down from 1.7 percent a year earlier.

Richard Donnell, executive director at Zoopla, described the pace of market activity as “a sharper slowdown than usual,” attributing the decline to higher borrowing costs and political volatility affecting buyer confidence. Mortgage rates, which were relatively stable last year at around 4.1 to 4.3 percent for a five-year fixed loan at 75 percent loan-to-value, surged to roughly 5 percent in April following heightened geopolitical tensions related to the renewed conflict involving Iran. Rates have since eased slightly to around 4.75 percent as of July.

“As a rule of thumb, the closer these mortgage rates are to 5 percent, the bigger the impact on the housing market,” Donnell said. This sentiment was echoed by Aaron Strutt, product director at mortgage broker Trinity Financial, who noted that several major lenders—including HSBC, Barclays, Santander, and Halifax—implemented multiple rate increases on fixed and tracker mortgages in recent weeks.

Regional variations were apparent in the data. North-east England stood out as the only region to record an increase in sales agreed, rising 4 percent year on year. Conversely, three-quarters of smaller local markets recorded declines in transactions. Locations such as Warrington, Hull, and Dundee led areas with rising sales, while Bath, Oxford, and Harrow saw both lower sales and flat or declining house prices.

Zoopla attributed this north-south disparity chiefly to cost differences. The generally lower average housing prices in the north-east meant that hikes in mortgage rates translated into smaller monthly payment increases for buyers there compared to those in more expensive southern regions.

Buyer interest, as measured by property inquiries, dropped 23 percent year on year over the same four-week period, signaling weakening demand. Meanwhile, Bank of England figures showed mortgage approvals rose slightly to 58,200 in June from 56,600 in May, but still remained below the decade average of approximately 65,000 to 68,000 per month.

The inventory of homes available for sale rose in all but three regions, further suggesting a shift toward a buyers’ market, according to Zoopla. Donnell noted that prospective sellers hoping to capitalize on seasonal demand typically seen in September would need to price properties competitively and act promptly, particularly if they have immediate plans to move.
