Modern Method of Auction Explained: How It Actually Works

The Modern Method of Auction combines the competitive bidding of a traditional auction with a timeline long enough for mortgage buyers to actually take part. Understanding the mechanics from the outset, particularly the reservation fee and the 56-day clock that follows, helps you manage it well rather than being surprised by it.

What actually is the Modern Method of Auction?

Sometimes called a conditional auction, it's an online sale process where your property is marketed with a starting bid and an agreed reserve price. Interested buyers submit online bids during the auction period, and the winning bidder pays a non-refundable reservation fee, then has 28 days to exchange contracts and a further 28 days to complete, 56 days total from the point the fee is paid. That's different from a traditional auction, where the fall of the hammer is exchange itself, and the buyer must complete within 28 days total.

Why does the 56-day structure matter so much?

The non-refundable reservation fee gives a level of commitment a private treaty sale simply doesn't have, where a buyer can walk away right up to exchange without penalty. The 56-day timeline, rather than the 28 days of a traditional auction, is what makes the process realistically accessible to mortgage buyers, since a standard mortgage application genuinely needs that kind of time. That broadens your potential buyer pool considerably. It reduces the risk of a fall-through compared with a standard sale, though it doesn't eliminate it entirely, since contracts aren't exchanged at the moment the reservation fee changes hands.

What happens behind the scenes?

Your auctioneer works with your conveyancer to prepare the auction legal pack, the documents buyers review before bidding: title documents, property information forms, searches, the EPC, and any special conditions of sale. You may already have some or all of this ready. The quality and completeness of this pack directly affects buyer confidence and how competitive the bidding actually gets. Your property is marketed online for a defined period, usually a few weeks, after which the auction closes and a winning bidder is identified.

What should you actually do before instructing?

Agree your reserve price with the auctioneer, the genuine minimum you'll accept, since the starting bid is deliberately set lower to encourage interest and competitive bidding. Instruct your conveyancer as early as possible so the legal pack can be prepared without delay, this is the single biggest lever you have over how smoothly the whole process runs. Make sure the property is accessible for viewings throughout the marketing period. Read the auctioneer's terms carefully, including their fees and what happens if the property doesn't reach reserve.
