London's residential auction rooms logged a clearance rate of 67 percent across major lots sold this week, according to data compiled by Allsop and EIG Property Auctions — a figure that sounds healthy until you examine what didn't sell. Thirty-three lots passed in across rooms in the City, South London and East London, a disproportionate number of them in the £600,000-to-£900,000 bracket that has quietly become the market's dead zone.
That middle band matters. It sits too high for the wave of buy-to-let investors circling sub-£500,000 stock since the government's stamp duty reform eased the surcharge for portfolio landlords in March 2026, and too low to attract the cash-rich buyers who cleared Mayfair and Kensington stock without blinking earlier this year. The result: a cohort of vendors who set reserves in January and haven't revisited them since, meeting buyers who have repriced everything by at least 5 percent since April.
Where the Hammer Stopped Short
The most striking cluster of passed-in lots came from a Barnard Marcus session held at the Novotel on Hammersmith Broadway on Wednesday. Seven of the 22 lots presented failed to sell, including a two-bedroom ex-local-authority flat on Askew Road, W12, guided at £485,000, and a Victorian mid-terrace in Catford, SE6, carrying a £695,000 reserve the room simply refused to meet. The Catford property — three bedrooms, a rear extension already signed off under a 2024 Lewisham planning consent — drew six registered bidders but only two active ones, and the second dropped out at £658,000.
Across town at the SDL Property Auctions livestream the same day, a ground-floor flat on Caledonian Road, N7, guided at £390,000 with a sitting tenant on a regulated tenancy, attracted no bids at all. Regulated tenancies are a recurring problem in the room: buyers know the legal and financial complexity of recovering vacant possession, and with county court backlogs still running at 14 months in Inner London, most won't touch them regardless of guide price.
Strettons, which runs a well-regarded East London room covering Hackney, Walthamstow and Romford, reported its own 71 percent clearance rate for the June 25 catalogue — but noted internally that three lots in the £700,000-to-£800,000 Hackney bracket passed in after failing to reach reserves set between six and nine months ago. Those vendors had priced against the Elizabeth Line corridor momentum that drove Hackney values up sharply through late 2024 and early 2025. That momentum has levelled off.
Sellers Are Still Fighting the Last War
The passing-in problem is, in most cases, a reserve problem. Auctioneers say the gap between what sellers expect and what the room will pay has widened noticeably since February. Estate agents who set ambitious reserve levels to win instructions six months back are now having uncomfortable conversations with clients after the hammer fails to fall.
One category moving against the trend: probate properties in Zones 4 and 5. Three lots in the Romford and Hornchurch area sold above guide at the Strettons June session, one — a semi-detached on Wingletye Lane, Hornchurch — selling for £387,000 against a £340,000 guide. Probate stock comes to market without the sentimental anchor of a living owner's price expectation, and buyers know it.
For sellers considering the auction route in the remainder of the summer, the practical calculus has shifted. Setting a reserve at current market value rather than aspirational value — typically 10 to 12 percent below asking price in a private treaty context — is now essential to achieving a sale in the room. Properties that pass in once carry a stigma that follows them back to private treaty, where the days-on-market counter starts again. The next major London catalogues close for entries in late July, with Allsop's flagship residential session scheduled for September 4 at the Cumberland Hotel, Marble Arch. Vendors with difficult stock have roughly three weeks to decide whether to reprice or hold.
