Property auctions have a reputation for being fast, dramatic and a bit intimidating. Blink at the wrong moment and you might buy a house, or so the joke goes. The reality is calmer, but there is a serious point underneath: when the hammer falls, you are legally bound to buy. There is no cooling-off period and no chance to renegotiate.
That makes preparation everything. Done well, auctions can be a quick, transparent way to buy, with a fixed completion date and no risk of gazumping. Done badly, they can cost you your deposit. Here is how to approach it step by step.
Why people buy at auction
Auctions suit buyers who value certainty and speed. Once the hammer falls, contracts are exchanged and the sale is committed. Typical reasons to consider one include:
- Speed: completion is usually set at 28 days, far quicker than the average chain-dependent sale.
- Certainty: the seller is bound too, so gazumping and gazundering are off the table. Our guide on gazumping and gazundering explains why that matters.
- Variety: auctions often include properties needing work, unusual homes, probate sales and investment lots.
- Transparency: everyone bids openly, so you can see exactly where the price lands.
The trade-off is that you do the homework up front, before you know whether you will win.
Step 1: Understand the type of auction
Not all auctions work the same way, and the difference matters.
Traditional auctions
This is the classic format. You pay a deposit on the day (usually 10%) and must complete within a set period, normally 28 days. Fail to complete and you can lose the deposit and face further costs.
Modern method of auction
Sometimes called conditional or reservation auctions. You pay a reservation fee when your offer is accepted, then have a longer period, often around 56 days, to complete. It feels more like a normal purchase, but the reservation fee is generally non-refundable if you pull out. Read the terms closely.
Our auctions explainer covers the basics if you want a quick refresher.
Step 2: Line up your money first
Auction finance is unforgiving because the timeline is fixed. You need to know, before you bid, exactly how you will pay.
- Cash buyers: have funds ready in an account you can access quickly, and confirm how the deposit must be paid on the day.
- Mortgage buyers: speak to a broker before you bid. Not every lender is comfortable with a 28 day completion, and the property must usually be mortgageable. A home with no working kitchen or bathroom, for example, may not be.
- Bridging finance: some buyers use a bridging loan to bridge the gap, but it is short-term and costly, so work out your exit plan before you commit.
If you are borrowing, a mortgage in principle is a sensible starting point, though remember it is not a guarantee. Only bid up to a limit you have set in advance and can genuinely afford.
Step 3: Do your homework on the property
Auction catalogues are brief. The detail sits in the legal pack, which is normally available online before the sale and should be read by a solicitor before you bid.
Look out for:
- Title and ownership: any restrictions, covenants or rights of way that affect what you can do with the property.
- Lease details: for flats, the length of the lease, ground rent and service charges. A short lease can be expensive to fix, as our guide to extending your lease shows.
- Searches: local authority and drainage searches that may reveal planning or enforcement issues.
- Special conditions: these can add extra costs or obligations and override the standard terms.
- Tenancies: if someone is living there, find out what rights they have and whether the property is sold with vacant possession.
Always view the property in person if you can, and consider a survey. A full building survey is rarely practical on a tight timeline, but even an inspection from a surveyor or builder can save you from nasty surprises. Our house survey guide explains the options.
Step 4: Know the full cost
The hammer price is not the whole bill. Budget for:
- Deposit: usually 10% of the price, paid on the day and put towards the purchase.
- Buyer's fees: many auction houses charge an admin fee or buyer's premium, and the amount varies a lot between firms. Check the catalogue terms.
- Legal costs: your solicitor will do more work than on a standard purchase, so expect to pay for the legal pack review.
- Stamp duty: calculated on the price you pay, and the rules depend on whether you are a first-time buyer, a home mover or buying an additional property. See our stamp duty explainer.
- Works and running costs: many auction properties need renovation, so build in a realistic contingency.
Add it all up before you set your maximum bid, not afterwards.
Step 5: Sort your solicitor and ID
Instruct a solicitor with auction experience early. They will review the legal pack, flag problems and be ready to move quickly once you win. Because completion is so tight, a solicitor who is new to auctions can slow things down at the worst moment. For a reminder of how the process normally unfolds, see our conveyancing step by step guide.
You will also need to register to bid, which usually means proof of identity and address, and bank details if you are bidding by proxy or phone.
Step 6: Bid with a plan
On the day, or online if the sale is virtual, keep it simple:
- Set your ceiling: write down your maximum price, including fees, and do not break it.
- Watch a few lots first: it helps you get a feel for the pace and the auctioneer's style.
- Bid clearly: make your bids visible and decisive rather than hesitant.
- Stay calm: auctions are designed to create urgency. Remember that another property will come along.
Many lots also carry a reserve price, which is the minimum the seller will accept. If bidding does not reach it, the lot may be withdrawn or negotiated afterwards.
Step 7: If you win
When the hammer falls, you will be asked to sign the memorandum of sale and pay your deposit straight away. Contracts are then exchanged. From that point:
- Insure the property: responsibility for the building often passes to you on exchange, so arrange cover immediately.
- Instruct your solicitor: they will deal with the remaining paperwork and prepare for completion.
- Keep your finance on track: chase your lender or arrange funds well ahead of the deadline.
- Complete on time: missing the date can mean losing your deposit and paying penalty interest.
Is auction right for you?
Auctions reward the organised. If you can move fast, have your funding ready and are comfortable doing detailed due diligence, they can be an efficient route to a home or investment. If you like time to think, a conventional purchase is often less stressful.
If you are buying with a rental in mind, think about what happens next as well. Our tenant find service can help you secure a good tenant quickly, and our fully managed service takes the day-to-day work off your plate. And if you are thinking about selling a home rather than buying one, you can sell your home with Moovehub for a flat fee.
