Pre-auction — bid before the hammer
Auction lots within 72 hours of hammer-down where the auctioneer is taking pre-auction bids below guide. The lots that didn't generate enough buyer interest are exactly where the operator-priced bid lands a deal.
Why the 72-hour pre-auction window is the sweet spot
Auctioneers publish guide prices roughly six weeks out from the auction date. In the final 72 hours, if a lot is not generating enough buyer interest to clear the reserve, the auctioneer or the seller's solicitor will often accept a pre-auction bid below the guide — on the basis that a guaranteed bid in hand beats the risk of the lot being passed. We track every UK auction lot inside the 72-hour pre-hammer window across all major auction houses (Allsop, Auction House UK, Savills, SDL, Pugh, Strettons, Network Auctions, McHugh and 30+ regional houses), flag the lots where the seller has signalled openness to pre-auction bids, and rank by the spread between guide and estimated market value.
Time-stamped window
Every lot shows the live countdown to hammer-down. The 24-48h window is where the auctioneer is most flexible.
Below-guide flagging
We flag the lots whose guide has already drifted, the lots being relisted from previous unsold auctions, and the lots with thin viewing logs — all signals the seller wants the lot off the books.

Frequently asked questions
How does a pre-auction bid work?
You submit an offer to the auctioneer or the seller's solicitor before the auction date, typically with a 10% deposit and proof of funds. If accepted, the lot is withdrawn from auction and you exchange contracts immediately (28-day completion, same as winning at the hammer). The auctioneer keeps a smaller commission than they would at hammer; the seller gets certainty. The auctioneer's pre-auction acceptance email is the contract trigger.
Why would a seller accept below guide?
Auction guide prices are usually set 10-20% below the reserve to attract registrations and viewings. A guide is not a reserve. If 72 hours out the seller's solicitor sees thin viewing logs and few registered bidders, a bid at or just below guide is a guaranteed sale — whereas an unsold lot has to be relisted at a different auction, which costs the seller fees and 6 weeks.
What if I win at the hammer instead?
Winning at the hammer locks you in too: 10% deposit on the day, 20-business-day completion (typical), no chain, no survey contingency. You must have proof of funds and a legal pack reviewed before the auction. The risk on auction day is that someone else bids you up — pre-auction removes that risk for a flat price.
Do I need bridging finance?
Usually yes. Most auction lots require completion in 20-28 business days, which is too tight for a high-street mortgage. Bridging finance at 70-75% LTV gets you to completion; you refinance onto a standard BTL mortgage in month 3-6 once any refurb is done. Some auction houses have started offering 56-day completion terms which open the door to high-street finance — we flag those.
