Eight in 10 Prime London Homes Now Sell Below Asking Price

Eight out of 10 properties in London's most exclusive neighbourhoods — Mayfair, Belgravia and Knightsbridge among them — now sell below asking price, according to research by Coutts, the private bank serving wealthy clients.

Properties in prime central London are changing hands at an average 10% discount to their asking price, Coutts found. Prices in the city's most expensive postcodes dropped 5% in the third quarter of 2026. The slowdown in the UK property market has now reached its wealthiest residents, and some affluent homeowners face hundreds of thousands, if not millions, of pounds in losses on the value of their homes.

Prices at the top end of the London market sit 14% below their 2014 peak. The market has absorbed a sequence of shocks since then: Brexit, the Covid pandemic, higher property taxes and a surge in borrowing costs. Buying and selling agents in the capital have also reported a slowdown in interest from foreign-born buyers following the abolition of the non-dom tax regime.

Which areas have fallen furthest?

Knightsbridge and Belgravia top the table of declines, with prices 30.8% below their peaks, Coutts said. South Kensington follows at 26.9% below its high-water mark. Those figures set the fashionable west London postcodes apart from the wider prime market, which is down 14% on average.

Alex Webster, head of lending at Coutts, said buyers and sellers at the top end of the market were taking a more cautious approach, even before the chancellor, John Healey's, first budget this week.

Sellers will now be watching to see if the budget "encourages some of that delayed activity to return", she said. "But financing conditions and the wider economic environment will continue to influence the market."

What is happening to rates?

The Bank of England has held its base rate at 3.75%, with no change since last December. But volatility in the bond market has driven up the swap rates that influence the pricing of fixed-rate mortgages.

Expectations are growing that the Bank's monetary policy committee will vote to raise the rate to 4% next week — the first increase in three years. That prospect adds pressure on financing costs for buyers in a market already priced for caution.

Are sellers pulling back?

They are. Coutts found new listings in prime central London down 14% compared with the previous quarter. Available stock is down 6% year-on-year.

Transactions fell 9.1% in the third quarter of this year. The biggest slowdown came in the £2m-£5m band, where transactions dropped 22.3%.

Where is the market still moving?

Separate research from the estate agent Savills shows activity concentrating at the very top of the market. Savills counted 26 transactions above £10m in the third quarter of this year, taking the total to 127 over the past year. Together, those sales were worth £2.88bn.

The contrast is stark. The £2m-£5m segment is stalling while nine-figure wealth keeps transacting above the £10m line. Webster's framing points to what comes next: the budget may unlock delayed deals, but financing conditions and the wider economy will keep setting the pace in prime central London.
