British home buyers need to put down an extra £18,200 deposit to keep monthly mortgage repayments at January 2026 levels, according to property portal Zoopla.
Average five-year fixed mortgage rates have risen from below 4 per cent in January 2026 to around 4.8 per cent today. The increase follows higher future inflation expectations influenced by the war in Iran.
Due to rising borrowing costs, a buyer who could previously afford a £200,000 mortgage while keeping their monthly payment unchanged can now borrow only around £182,000 for the same monthly outlay.
In London, typical buyers face the largest financial hurdle, needing to add £35,500 to their deposit to offset higher interest rates, which is almost double the national average.
By contrast, lower house prices mean that buyers in the North East of England need an additional £10,200 deposit to maintain the same monthly payment level.
Regional property prices and buyer demand
The extra cost of purchasing a home has kept house prices flat or falling in several southern regions over the past year. Property prices have fallen by 0.3 per cent in the South East and by 1 per cent in London.
Jeremy Leaf, a north London estate agent, said: "On the ground, modest rises in mortgage costs have reinforced the buyer’s hand and are resulting in lower offers, particularly for flats, many of which have remained unsold for some time."
Leaf added: "We know too that listings will increase over the next few weeks bearing in mind a recent rise in appraisals which will further strengthen buying power."
Further north, where the impact of higher mortgage rates is less severe, property prices continue to rise. Zoopla reports that typical home prices over the past year have grown by 1.5 per cent in the West Midlands, 1.7 per cent in Yorkshire, 2.5 per cent in the North East, and 3.1 per cent in the North West.
Overall transaction activity slowed over the summer, with sales volume down 6 per cent year-on-year as more buyers remained on the sidelines. The low point for market activity occurred in mid-July around the time of the World Cup final.
Search activity and market outlook
Despite fewer completed sales, prospective home buyers are returning to online portals. Searches for properties on Zoopla are up 7 per cent year-on-year, marking the largest increase since mortgage rates jumped in the spring following the Iran conflict.
Zoopla reported that house searches are higher across every region and country in Great Britain for the first time since August 2025. The strongest recovery in search activity has occurred in the South East and the East of England, while the North West has recorded barely any uptick in buyer demand.
The website noted that an increase in search activity indicates prospective buyers are beginning to plan moves, although it will take time before online interest feeds into formal viewings and offers.
Signs suggest the gap to last year in sales and buyer demand is starting to close. However, buyers retain considerable choice, with 5 per cent more homes listed on the market than at the same time last year.
Asking price reductions and market forecasts
Late August and early September typically see an increase in asking price reductions as sellers adjust expectations to attract autumn buyers. Analysts indicate that this seasonal repricing could drive the average British house price lower.
Although the annual rate of overall house price growth remained positive at 0.9 per cent in the year to July, that figure reflects a decline from 1.3 per cent in June. Multiple house price forecasts revised over the summer indicate that average prices will end 2026 lower than where they began the year.
Richard Donnell, executive director at Zoopla, said: "Many buyers have taken a ‘wait and see’ approach over the summer months in response to higher borrowing costs and political uncertainty."
Donnell added: "The low point for activity was mid July around the time of the World Cup final. Since then we have seen a steady increase in the number of people searching for a home, assessing their options ahead of the post holiday rebound in sales market activity. This is a nationwide trend and the first time searches for homes are up across Britain this year."
Mortgage market context and lender rates
The sudden increase in mortgage rates stems from inflation triggered by the conflict with Iran, which reversed previous expectations that the Bank of England would lower benchmark interest rates. The shift leaves both prospective buyers and existing homeowners facing increased borrowing expenses when purchasing or remortgaging.
Mortgage products available in the UK market typically include fixed-rate agreements ranging from two-year, five-year, to ten-year terms, as well as variable-rate deals offered by commercial lenders across Britain.
