UK house prices fell by 0.4% annually and 0.2% monthly in August 2026, reaching an average price of £298,468, down £685 from July, according to Lloyds data [1, 2, 3]. This marks the first year-on-year decrease since November 2023 and below economists' expectations of modest growth [1, 2, 3].
The decline comes amid rising mortgage interest rates, which averaged around 5.6% for two-year fixed deals and 5.66% for five-year fixed mortgages in early September 2026, up from below 5% at the start of the year [1]. Higher borrowing costs, combined with geopolitical tensions—especially the ongoing US-Iran conflict—and stretched affordability, have squeezed many prospective buyers [1, 2, 3].
Mortgage approvals have fallen to their lowest level since early 2024, signaling reduced buyer activity [1]. Sellers remain reluctant to cut prices, while many buyers are holding off, waiting to see how market conditions evolve. Andrew Asaam, director at Lloyds, said, "What we’re not seeing is a rush of homeowners cutting prices. But more are choosing to sit tight, with sellers reluctant to accept offers they feel are too low while some buyers are waiting to see how conditions develop" [1].
Regional differences were notable. Northern Ireland saw house prices grow 6.9% year-on-year to £231,245, Scotland prices were up 3.5% to £223,437, and Wales rose 0.6% to £230,282, showing pockets of resilience within the UK market [1].
Recent data from Nationwide Building Society painted a different picture, showing 1.6% annual house price growth and a 0.2% monthly increase in August 2026 [2, 3]. Meanwhile, official UK government figures showed slower growth of 2.0% for the 12 months to June 2026, compared with 3.0% growth a month earlier [2, 3].
Estate agent Jeremy Leaf noted, "There is more movement when sellers set realistic asking prices from the outset and appreciate after a period of marketing that even a cheeky offer is worth considering. Activity is picking up now that the main holiday season is over, which is helping to improve confidence a little" [1].
Ruth Gregory, deputy chief economist at Capital Economics, forecast house prices would largely flatline for the rest of 2026, projecting a modest 1.5% annual increase by the fourth quarter [2]. Lloyds’ Andrew Asaam also highlighted the impact of economic uncertainty, saying, "The housing market has faced a more difficult backdrop in recent months, with the impact of global events on inflation and borrowing costs creating greater economic uncertainty" [2].
The next set of official house price data is expected in the coming months, which will shed further light on whether the market decline continues or stabilizes.
