The UK postcodes where Brits are taking £40k losses just to escape – is your area on the list?

BRITS are losing tens of thousands of pounds just to sell their flats, with the pain that has crippled London’s property market now ripping through cities nationwide. New data has laid bare the scale of the crisis, showing owners in Sheffield, Birmingham, Leicester and Newcastle are routinely selling for around £40,000 less than they paid. The figures, compiled by analytics firm PropertyData and first reported by This is Money, tracked every flat sale in England and Wales in the year to the end of May 2026. Each sale was cross-checked against what the seller had originally paid for the same property at any point over the previous two decades. Sign up for the Money newsletter Thank you!

Registered in England Number: 3368205 Wealthy commuter belt hotspots including Runnymede, Mole Valley, Hart, Woking, and Windsor and Maidenhead have also seen large numbers of owners forced to sell at a loss. Even upmarket Kensington and Chelsea in London has not escaped the trend, with widespread losses reported among flat sellers there too. On average, sellers who lost money were left £39,509 out of pocket, having held onto their flat for close to nine years. Land Registry figures show flats nationally are now worth less than they were four years ago, with average prices tumbling from a 2022 peak of just over £200,000 to £192,000 today. One in four flat sellers across Britain lost money over the past year, but city centre flats are being hit hardest of all. Experts told said the crisis boils down to a toxic mix of oversupply, leasehold costs and lingering safety fears. Buying agent Nicholas Finn, of Garrington Property Finders, told This is Money, the main driver was simply too many flats chasing too few buyers. “We always talk about there being a UK housing crisis, but I’m not so sure we have a flats crisis,” he said. “The skyline across so many cities is dominated by cranes.” Birmingham agent Philip Jackson, of Maguire Jackson, said he had counted 1,400 flats for sale within a mile of his office alone, including one block with 30 near-identical one-bedroom flats on the market at once. “The chill of London has hit Birmingham,” he said. “It is the worst sales market I have ever known.” New-build flats typically sell at a premium, meaning owners who bought within the past few years are almost guaranteed to lose money when they sell. Jackson said falling investor demand was compounding the problem, with landlords who bought between 2015 and 2020 now often selling for no more than they paid. He also blamed the lingering fallout from the cladding scandal that followed the Grenfell Tower tragedy, saying it had left many flats effectively unsellable. Leasehold charges are adding to the misery, with service costs for maintaining blocks soaring in recent years. Figures from The Property Institute show average annual service charges have jumped 41% since 2019, now totalling £3,634 a year. Zoopla’s Richard Donnell pointed to a glut of buy-to-let flats built during the 2000s and 2010s boom as the key factor behind losses in the North East. He said commuter belt flats snapped up during the ultra-low mortgage rate years between 2016 and 2021 had left many owners exposed once rates began climbing. Comment now
