Buying

Traditional vs conditional auctions explained

Every lot is sold by one of two methods, and it changes how much you pay on the day and how long you have to complete. Here is how they differ.

Traditional auction

When bidding ends, the highest bidder is legally committed. Contracts exchange immediately, the buyer pays a deposit (commonly 10% of the price) and completion usually follows within about 28 days.

Best for: cash buyers and investors with finance ready, and sellers who want maximum certainty.

Conditional auction

Often called the modern method of auction. The winning bidder pays a non-refundable reservation fee and gets a longer period to exchange and complete, often around 56 days in total. That extra time suits buyers who need a mortgage.

Best for: buyers using a mortgage, and properties that appeal to owner-occupiers as well as investors.

Always check the lot

Terms vary between auction houses and between lots. The method, fees and timescales for each property are shown on the listing and in its legal pack. Read them before you bid.

Which should a seller choose?

Traditional gives you the fastest certainty. Conditional can widen the pool of bidders by including mortgage buyers. We'll recommend a method when we value your property, based on its type and who is most likely to buy it.
