London Auction Roundup: The Properties That Passed In and Why

More than a quarter of lots offered at central London property auctions this week failed to sell, with high-value homes in zones 1 and 2 seeing a notable spike in pass-ins. Among the unsold were a South Kensington maisonette guided at £2.15 million and a Victorian terrace in Hackney given a reserve of £1.05 million. Auctioneers struggled to coax opening bids even as some sellers trimmed expectations at the last minute.

The wave of pass-ins is worrying both sellers and agents. The capital’s auction rooms have been prized as fast routes to cash sales, but stalling demand signals deeper unease in the city’s property market. Against the backdrop of volatile inflation, climbing mortgage rates—the average two-year fix reached 5.9% last month, per UK Finance—and buyers becoming bolder with aggressive offers, vendors are realising that the old certainties are gone.

Sellers Won’t Budge, Buyers Won’t Stretch

At Savills' sale in Margaret Street, eight out of 24 residential lots went unsold, with properties either failing to reach their reserve or withdrawn entirely before bidding. One such case was a Bloomsbury flat overlooking Brunswick Square, guided at £940,000. The highest offer fizzled out at £890,000. “We’re seeing a standoff,” said one auctioneer. “Sellers want last year’s prices, but buyers are only biting if there’s a real bargain.”

A similar story played out at Allsop’s Marble Arch ballroom, where a run-down three-bed in Tufnell Park drew just two tentative bids before being passed in at £710,000—well below its £795,000 reserve. According to auction records reviewed by The Daily London, clearance rates for June in Greater London fell to 72%, down from 81% during the previous summer quarter. The drop-off is most pronounced among lots above £1 million, particularly period homes in Islington, South Kensington, and the increasingly pricey parts of Ealing.

High Hopes, Higher Hurdles

The reasons for pass-ins are manifold, but market insiders point first to stubborn reserves. Sellers, especially those not under immediate pressure to move, have proved slow to acknowledge the softening market. Meanwhile, buyers—many of them cash-rich but ultra-cautious—are leveraging every headwind, from looming interest rate hikes to uncertainty around new regulation of short-term lets, to negotiate harder. “People remember the price readjustment in 2020, and they’re betting they can wait out today’s sellers too,” an east London agent said.

For buyers eyeing upcoming sales, due diligence and patience are key. Properties that pass in often enter private treaty negotiation at lower prices in the week following the auction, and some auctioneers—like Barnard Marcus in Hammersmith—report 40% of their unsold stock trading within ten days, typically at around 5-10% below the final auction bid. Savvy house-hunters should flag interesting lots with agents and be ready to move quickly if reserves are revised post-auction.

For sellers hoping the autumn ushers in a rebound, market watchers caution that patience and flexibility go hand in hand in the current climate. As the city waits for direction from both the Bank of England and the new housing supply incentives announced for 2027, the auction room verdict stands: price it right, or risk being left behind.
