The UK housing market slowdown has been sharper than usual this summer, with sales agreed over the past four weeks running 9 per cent below last July’s level, according to Zoopla. Stock is building, buyers are negotiating harder and average prices in London and the southeast have gone into reverse.
For investors, the headline number masks a market splitting in two. Southern England is softening under the weight of dearer homes and higher borrowing costs, while northern cities are quietly delivering the strongest gains in the country.
Rates and politics take the wind out of the market
Richard Donnell, executive director at Zoopla, blamed “elevated mortgage rates and political uncertainty” for a market that stalled through spring and into summer.
He estimated that rate rises since January have added about £125 a month, or £1,500 a year, to repayments on a typical UK home. The Bank of England’s quoted household interest rates data tracks how advertised mortgage pricing has moved over the period.
Estate agents had already suggested a triple distraction was at work: a new prime minister, the World Cup and the prolonged hot weather. Donnell put it more plainly. “For anyone who doesn’t need to move, it’s entirely reasonable to wait and see how things settle,” he said, pointing to instability in the Middle East and Andy Burnham’s arrival in Downing Street.
Buyers gain serious negotiating power as stock builds
With fewer sales being agreed, more homes are sitting unsold. Zoopla’s latest house price index shows more homes for sale in eight of the UK’s 11 regions than a year ago.
That extra choice is handing buyers what Donnell calls “serious negotiating power” and holding back prices, particularly in the south of England, where higher-value homes are more sensitive to mortgage costs.
The numbers bear that out. The average London home has lost £3,270 in value over the past 12 months, according to Zoopla, while prices in the southeast are down £1,480 on average.
A hardening north-south divide
The northwest of England tells a very different story, with property values up £7,100 since last summer. Across the UK as a whole, annual house price inflation is running at 1.3 per cent, down from 1.7 per cent a year ago.
Zoopla’s three coldest local markets, where sales and prices have stalled, are Bath, Oxford and Harrow. Its hot spots are all northern: Warrington, Hull and Dundee, a pattern consistent with the buy-to-let hotspots accessible with a £25,000 deposit we have highlighted before, and with the regional winners identified in our UK housing market outlook for 2026.
Donnell stressed it was “not all one-way traffic”. He said: “Sales are still getting done, house prices are still rising in most of the country and buyers have more room to negotiate than they’ve had in some time.
“Conditions can vary sharply from place to place, with almost three quarters of local markets having seen sales fall over the past three months, but a quarter are bucking that trend entirely.”
What this means for investors
Donnell expects a “September pick-up”, provided mortgage rates rise no further. The market typically bounces in early autumn, after the school holidays and before the run-up to Christmas, and Zoopla had already forecast that pent-up demand would return in 2026.
For landlords and portfolio investors, the immediate opportunity sits in the imbalance. Well-stocked southern markets offer rare leverage for cash-ready buyers prepared to negotiate hard, while the northwest and northern cities continue to combine lower entry prices with the strongest capital growth. The variable to watch between now and September is mortgage pricing: if rates hold or ease, the autumn window could be the best buying moment of the year.
