London auction clearance rates hit eight-month high as summer bidders defy the heat

London's residential auction market posted a clearance rate of 78 percent across the four weeks to 4 July 2026 — the strongest monthly figure since last October and a sharp jump from the 61 percent recorded in the same period a year ago. The data, compiled from results filed by the major London auction houses including Allsop, Savills and Barnard Marcus, covers roughly 1,400 lots brought to market across June and into early July.

The timing matters. Mortgage approvals have been climbing since the Bank of England cut the base rate to 3.75 percent in May, and buy-to-let investors — many of whom sat on the sidelines through the stamp duty surcharge years — are returning to the room. The government's partial reform of the Additional Dwelling Supplement in the March 2026 budget reduced the surcharge on properties below £300,000, opening a direct pipeline of lower-value lots back to landlord buyers who had been priced out of conventional estate agency channels.

Where the lots are landing

Romford has become one of the most active auction postcodes in Greater London over the past month. Lots along South Street and in the RM1 postcode have been clearing at a rate above 85 percent, with terraced houses achieving guide prices of between £280,000 and £320,000 and then selling above reserve by an average of £14,000. Elizabeth Line connectivity to Canary Wharf in under 25 minutes has made Romford attractive to a new tier of commuter buyer who can't afford Stratford's £480,000 median flat price.

Inner east London is also moving fast. The Auction House London room — which relocated its principal monthly sale to the Radisson Blu Edwardian at Heathrow last autumn but retains a significant Hackney and Tower Hamlets book — reported that 34 of 41 lots offered at its 18 June sale found buyers on the day. That's an 83 percent clearance rate from a single session, with a converted warehouse unit on Queensbridge Road in Dalston going for £412,000 against a guide of £375,000.

North of the river, Walthamstow continues to punch above its weight. The E17 postcode has appeared in the top five London auction postcodes by volume every month since February, a run that coincides with the expansion of walking-distance development around the Blackhorse Road corridor.

The numbers behind the surge

Across the capital's four largest auction houses by London lot volume — Allsop, Savills, Barnard Marcus and Auction House London — the combined June 2026 total raised was approximately £387 million, up from £291 million in June 2025. The average lot size rose modestly to £276,000, suggesting volume rather than price inflation is driving the revenue jump. Unsold lots are being relisted faster too: the average time between a passed-in lot and its next auction appearance has dropped to 19 days, down from 31 days in the first quarter of this year.

Repossession stock, which peaked as a category in late 2024 and early 2025 when mortgage arrears were running at a 12-year high, has begun to thin. That is compressing supply at the lower end of the market and pushing competitive bidding into the £350,000–£500,000 bracket, territory that estate agencies have traditionally dominated.

For buyers considering the auction route, the next major London calendar dates are Allsop's residential sale on 23 July at the Intercontinental London Park Lane, and Barnard Marcus's session on 16 July at the Grand Connaught Rooms in Holborn. Both catalogues are expected to feature significant volumes of Zone 4 and Zone 5 stock. Bidders should have finance — ideally a mortgage agreement in principle — confirmed before entering the room. Exchange is immediate on the fall of the gavel, with a standard 10 percent deposit due the same day and completion typically required within 28 days. At current clearance rates, sitting on the fence is becoming an expensive habit.
