Buying at Property Auction UK

Property auctions can be a brilliant way to bag a bargain, but they are not for the faint-hearted. When that gavel falls, you are legally committed to buy — no cooling off period, no changing your mind. This guide covers everything you need to know before bidding.

How Property Auctions Work

Auction houses publish catalogues 2-4 weeks before the sale. Each property has a guide price (often deliberately low to attract interest) and a reserve price (the minimum the seller will accept). On auction day, bidding starts and the highest bidder above the reserve wins. You pay a 10% deposit immediately and must complete within 28 days.

Why Properties End Up at Auction

Repossessions, probate sales, properties needing major work, unusual properties that are hard to mortgage, and sellers wanting a quick guaranteed sale. This means bargains exist but so do money pits. Due diligence is essential.

Before the Auction

Get finances sorted first. You need either cash or a pre-approved auction mortgage (bridging finance works too). Standard mortgages take too long for the 28-day completion deadline. View the property. Never bid blind. Visit at least twice, at different times. Read the legal pack. This contains title documents, searches, and special conditions. Pay a solicitor 200-300 GBP to review it. Get a survey. Even a basic one can reveal deal-breakers. Set your maximum bid and stick to it absolutely.

Costs to Budget For

Purchase price, plus: 10% deposit on the day, auctioneer buyer premium (often 2-3%), solicitor fees, survey, stamp duty, and renovation costs. Many auction properties need significant work — budget 20-30% of purchase price for refurbishment as a rule of thumb.

Online vs In-Person Auctions

Online auctions have exploded since 2020. They often run for 30 days with a countdown timer. The process is similar but you typically get 56 days to complete instead of 28. Major online platforms include iamsold, SDL Auctions, and Auction House.

Tips for Success

Attend several auctions as an observer before bidding. Have your solicitor and surveyor ready to act fast. Check comparable sold prices on the street. Factor in ALL costs before setting your maximum. Do not get caught up in bidding wars — there will always be another property.
