A Step-by-Step Guide to Selling Property at Auction in the UK
Selling a property at auction in the UK means agreeing a guide price, setting a confidential reserve and completing the sale within 28 days. This property auction guide runs from valuation to completion. It answers how to sell a property at auction in the UK and who the buyers actually are. With Prime Property Auctions, you set the figure, pay nothing upfront, and pay nothing unless we sell.
Why Sellers Pick an Auction House Over an Estate Agent
Speed and certainty are what an auction delivers. Unlike an estate agent sale, which takes roughly five to six months from listing to legal completion. Around a quarter of agreed sales then collapse before the keys change hands. Auction turns that around. Once the hammer falls, contracts are exchanged, a deposit is paid, and the buyer who walks away loses money.
Sellers come to us for a handful of reasons. The property has gone stale on the open market, is uninhabitable, has a short lease or has a title quirk that puts lenders off. It could also be that life is moving faster than the usual selling process, and a quick sale beats squeezing out the last few thousand pounds. Executors, landlords exiting an investment and sellers burned by a collapsed chain all use it.

The Auction Process From Start to Finish
Six stages take you from the first call to money in the bank. Most of the heavy lifting is managed by us.
Step 1: Book a Free Valuation and Agree a Guide Price
We look at comparable sales, current demand and the condition of your place, then talk you through what buyers will realistically pay. The guide price we publish is a marketing figure meant to attract interest, not a forecast. Pitch it sensibly and you attract more potential buyers, which drives competition later.
Step 2: Set Your Minimum Reserve Price
The reserve price is the lowest amount you will accept. It stays confidential, and nothing sells below it. As the seller, you can adjust the figure at any point before bidding opens.
Step 3: Instruct a Solicitor and Prepare the Legal Pack
Auction front-loads the legal work. Your solicitor gathers the title deeds, searches, any factoring or leasehold paperwork and the special conditions of sale. Prospective buyers can read that pack before they bid. No solicitor yet? We will introduce you to someone who can provide a quote for the conveyancing, as covered in our auction FAQs.
Step 4: We Advertise and Market Your Property for Free
We handle everything. Professional photos, a video tour and a floor plan cost you nothing, and neither does the listing on Rightmove and Zoopla. Your lot then lands in front of our buyer list. Marketing runs for a few weeks, giving prospective bidders time to read the paperwork and arrange funds. Owners of land and commercial units get the same deal.
Step 5: Bidding Opens & the Offers Arrive
Our online property auctions run fortnightly, and the bidding process is transparent, so everyone can see the highest bid. Offers can be made the moment your lot goes live, and Prime reports that 87% of listings sell before auction day. Early deals still follow the same auction terms, which keep potential bidders on a level footing. Our upcoming auction schedule shows what is coming next.
Step 6: You Complete the Sale in 28 Days
Meet your reserve, and the winning bidder pays a 10% deposit immediately, making the sale binding. Like traditional auctions, the contract is set the moment the hammer falls. There is no modern method of reservation fee here, where a buyer can hold your property for up to 56 days without being legally bound to buy. Completion follows within 28 days. Should the buyer fail to complete, the deposit is yours to keep, and we go back out to secure another.
Who Actually Buys a House at Auction
Our bidders are not one type of person. Around 20,000 buyers sit on the Prime list. Landlords hunting rental yield make up a large share, and they like tenanted stock because the rent starts on completion day. Developers and flippers chase anything with headroom, from a derelict cottage to a plot with lapsed planning. You can see what they look for in our guide to buying at auction.
Owner-occupiers turn up far more often than people expect, usually priced out of the open market and happy to take on a project. Mortgage buyers are welcome as well, though they tend to want a longer completion window. That offer is yours to accept or decline. Demand is real rather than theoretical, too. Residential property lots sold at UK auctions rose 21.3% in November 2025, with more than two-thirds finding a buyer.
What It Costs to Sell a House at Auction
Most auction houses charge sellers in three or four ways. You will meet an entry fee before your lot reaches the catalogue, a marketing charge and a withdrawal fee if you change your mind. A commission of roughly 2.5% then follows a successful sale. Estate agent fees average about 1.42% including VAT, and you wait months for a completion that carries a real risk of collapse.
Prime works differently. There is no entry fee, no marketing spend and no upfront money of any kind. Our fee only becomes payable once your property sells, as set out on our sell your property page. Buyers pay a separate premium to the auctioneer on top of the purchase price, as set out in our auction terms and conditions.
Which Properties Get the Best Price at Auction?
Almost anything can be sold at auction, though some lots simply perform better. Renovation projects, ex-rental flats and tenanted stock all appeal to our cash-ready bidders. So do plots of land and commercial units, where potential matters more than a perfect kitchen. Residential lots with a clean title draw the strongest competition.
Knowing how to sell property at auction is mostly about preparation. Condition, the legal pack and the reserve are the three factors that decide your result. Finish the paperwork early and keep the place open for viewings. If your home is pristine and priced at the top of the local market, an estate agency sale may suit you better. We would rather say so at the valuation than waste your time. On auction day, we manage the bids, handle the buyers and call you the moment your lot sells.
FAQs About Selling Property at Auction
Still weighing it up? These are the questions sellers ask us before they commit.
Yes, and it happens more often than people think. Nothing prevents you from selling a mortgaged property at auction. Your solicitor redeems the loan from the proceeds on completion. The only thing to check is that your reserve covers the outstanding balance plus fees. Ask your lender for a redemption figure before you set that reserve, because early repayment charges can apply.
Usually, but read the small print first. Most agency agreements include a sole selling rights period with a two- to four-week notice period. Under those terms, you can still owe commission even when we find the buyer. Serve written notice, note the date the contract ends, and ensure the auction day falls after it. If your agent then produces a keen cash buyer, let them bid alongside everyone else.
Nothing bad, and nothing expensive. If the top bid falls below your reserve, the lot remains unsold, and you owe us nothing, because our fee is only ever payable on a sale. The auctioneer can hold a bid below the reserve provisionally and put it to you, and that bidder is held to their figure for seven working days while you decide. Most sellers take one of three routes from there: accept the highest offer anyway, relist in the next auction with a reserve that reflects what the bidding told you, or walk away. Your property is not tied up either way.
