UK Flat Sales Stagnate as Borrowing Costs Rise

Eighty-eight percent of flats listed in inner London did not find a buyer within six months in 2025. This figure comes from Zoopla, which tracks national property trends. The gap between the value of a flat and a house is now the widest it has been in thirty years. Sellers face a market that has shifted away from urban apartments. The demand for spacious homes has outpaced the supply of flats.

The average price for a flat is down two percent from the same period last year. This is the largest drop seen for any property type. Compared to August 2021, flat prices have only risen by four percent nationally. Rightmove reports that only fifty percent of flats listed nationwide find a buyer. In contrast, sixty-five percent of houses are sold. The market shows a clear preference for detached or semi-detached homes.

Borrowing Costs Drive Down Demand

Major UK mortgage lenders increased loan costs in September. Higher interest rates reduce the number of affordable buyers. Service charges and ground rents add to the total cost of ownership. These expenses are often higher in flat complexes than in standalone houses. Buyers are increasingly concerned about these long-term liabilities. The complexity of leasehold arrangements further discourages potential purchasers.

Richard Donnell, executive director at Zoopla, cites post-pandemic social changes as a factor. People prioritize space for working from home. This shift benefits houses over flats. Inner London flats face additional pressure due to higher service charges. These buildings are often larger and more complex. The combination of cost and complexity slows down the sales process. The market reflects a broader change in housing preferences.

Seller Struggles in North London

James Schaife has tried to sell his one-bedroom flat in north London for four years. He purchased a thirty-five percent share of the property in 2017. The flat is part of a shared ownership scheme with Newlon Housing Trust. After moving out in 2022, he listed the property for sale. The initial nomination period generated almost no interest. He claims the housing association restricted his choice of valuers. This situation has delayed his plans to start a family.

Schaife is currently renting out the property with a consent-to-let agreement. He says the housing association will not renew this agreement. A Newlon spokesperson states that strict rules protect the public purse. The company denies that the resale process is problematic. They emphasize the need to limit subletting risks. The dispute highlights the friction in the shared ownership market. Sellers face bureaucratic hurdles that can stall transactions.

London Faces Unique Market Headwinds

Colleen Babcock from Rightmove notes that London is heavily weighted towards flats. Affordability remains a key challenge in the capital. Higher stamp duty costs limit the pool of potential buyers. The Lifetime ISA provides less help in high-priced areas. First-time buyers and home-movers face specific hurdles. The market for flats in London is under particular strain. The decline in sales is a local and national issue.

The weakness in the flat market is not due to a single cause. It is a combination of high borrowing costs and ownership complexities. The reputation of flats has been damaged by rising expenses. Buyers are cautious about taking on long-term liabilities. The data from GN auto markets/housing: rental market confirms the trend. The sector is adjusting to a new economic reality. Prices may remain under pressure until costs decrease.
