Prime central London has become a buyer's market. Research from Coutts, reported by The Guardian on 31 October 2026, found that eight in ten homes in postcodes such as Mayfair, Belgravia and Knightsbridge now sell below their asking price, at an average discount of around 10%.
What the latest figures show
- Prime central London prices fell 5% in the third quarter of 2026 (Coutts).
- Top-end prices are 14% below their 2014 peak, with Knightsbridge and Belgravia 30.8% below and South Kensington 26.9% below.
- Transactions were 9.1% lower in the quarter, and 22.3% lower in the £2m to £5m band.
- New listings fell 14% on the previous quarter, so there is less choice as well as less competition.
Agents point to higher property taxes, the end of the non-dom regime and higher borrowing costs. The Bank of England base rate is 3.75%, and the Monetary Policy Committee announces its next decision on Thursday 5 November, with some in the market expecting a rise to 4%.
Why finance is now part of the negotiation
When most homes sell below the asking price, the buyer who can prove they are ready tends to have the stronger hand. A seller weighing two offers will often prefer the one with an agreed mortgage in principle, a clear source of deposit and a realistic completion date.
At this level, lenders look closely at more than salary. Bonus and carried-interest income, overseas earnings, investment portfolios and complex ownership structures all need careful presentation. Some private banks will also consider the wider relationship, such as assets placed under management, rather than income alone.
Costs to plan for
Stamp duty on a high-value home is a significant sum and is due on completion, so it should sit in your budget from day one. From April 2028, homes in England valued at £2 million or more will also face the new High Value Council Tax Surcharge, confirmed in the 28 October Budget. Factor both into what you can comfortably offer, not just what you can borrow.
Quick tips
- Get a mortgage in principle before you view, so your offer can be taken seriously straight away.
- Gather two to three years of income evidence, including bonuses and overseas earnings, plus a clear audit trail for your deposit.
- Compare high-street, specialist and private bank options: the right fit depends on your income, assets and structure.
- Use the asking-price gap to negotiate, but have your own valuation and survey done before you commit.
- Check how a rate change at the next MPC decision could affect your monthly payments, and when to lock in a mortgage offer.
