TL;DR: A reserve price is the minimum amount you’ll accept for your property at auction. It protects you from selling too low and gives you legal grounds to reject bids. Set it 85-95% of your property valuation, tell your auctioneer early, and understand the auction house fees that apply. PropSell helps sellers connect with auction houses for free.

How to Set a Reserve Price at Auction in the UK: Complete Guide

Selling your property at auction is a smart move. You get a quick sale, genuine buyers, and a fixed completion date. But one decision makes or breaks your auction success: your reserve price. This is the minimum amount you’re willing to accept. Set it too high and your property won’t sell. Set it too low and you lose money. In this guide, we’ll show you exactly how to set the right reserve price for your UK property auction and maximize your returns.

What Is a Reserve Price at Auction?

A reserve price is the lowest amount you’ll accept for your property. If bidding doesn’t reach this price, the auctioneer will not sell your home, even if someone is willing to buy it below that figure. You keep your property and can try again later.

The reserve price is confidential between you and the auctioneer. Bidders don’t know what it is. This protects your interests and encourages genuine bidding. The auctioneer will declare whether a property is sold “subject to reserve” or “without reserve” (meaning there’s no minimum). Most auctions have a reserve price because it gives sellers protection and control.

Why Should You Set a Reserve Price?

A reserve price gives you three big advantages. First, it protects you from accepting an offer that’s too low. Your property has a real value, and a reserve ensures you get paid fairly. Second, it gives you legal grounds to refuse the sale if bidding falls short. You’re not locked into a bad deal. Third, a reserve price often encourages better bidding because buyers know there’s a serious seller behind the property, not someone desperate to dump it at any price.

Without a reserve, you might sell your home for thousands less than it’s worth. Buyers know this and may bid cautiously. With a reserve, you signal confidence in your property’s value, which attracts serious bidders willing to compete.

How Do You Calculate the Right Reserve Price?

Your reserve should reflect your property’s true market value. Most auctioneers recommend setting the reserve at 85-95% of the property’s estimated value. Here’s how to work it out:

• Get a professional valuation from your auctioneer or a surveyor. This is your baseline.
• Calculate 85-95% of that valuation. This becomes your reserve range.
• Choose a number within that range. Be realistic about your local market.
• Talk to your auctioneer about recent comparable sales in your area.

For example, if your property is valued at £200,000, your reserve price should sit between £170,000 and £190,000. Don’t set it at £199,000 just because you hope for top dollar. That’s too high and will put off bidders. Equally, don’t drop it to £150,000 hoping to trigger a bidding war. That strategy usually backfires and you’ll sell too cheap.

What Happens If No One Bids Above Your Reserve Price?

If the highest bid falls below your reserve, the property is declared unsold. You keep it and can choose your next step. You might lower the reserve and relist at the next auction, negotiate a private sale with the highest bidder, or take it off the market entirely. There’s no penalty for being unsold at auction. You owe the auctioneer nothing because the property didn’t sell.

This flexibility is why a reserve price matters. It’s your safety net. You maintain control and can walk away if the price isn’t right. Many sellers use auction as part of a broader sales strategy. If the auction doesn’t hit your reserve, they might then explore a fast cash sale with a cash buyer for certainty and speed.

When Should You Tell Your Auctioneer Your Reserve Price?

Discuss your reserve price with your auctioneer before you formally instruct them to sell. Don’t wait until auction day. The auctioneer needs time to market your property accurately and prepare their strategy. Most auctioneers ask for your reserve at the initial appraisal meeting.

Be honest with your auctioneer about your reserve. They know the local market better than anyone. If your reserve is unrealistic, they’ll tell you. Listen to their advice. A good auctioneer will be transparent about whether your reserve makes sense for the current market and what it means for your chances of a successful sale.

What Auction Fees Should You Factor Into Your Reserve?

Your reserve price should account for auction fees. Most auctioneers charge a buyer’s premium (typically 10-15% of the sale price) that doesn’t go to you. They also charge a seller’s fee, usually 0.5-2.5% of the hammer price, plus VAT. Some charge a fixed fee instead. These costs reduce your net proceeds, so plan accordingly.

If your reserve is £180,000 and the auctioneer charges 1.5% seller’s fee plus VAT, you’ll take home less. Work backwards from your target take-home amount. If you need £175,000 net, your reserve might need to be £180,000 to cover the fees. Always ask your auctioneer for a breakdown of all costs in writing before you commit.

How Should You Prepare for Auction Day?

Once you’ve set your reserve, prepare properly. Attend the auction if possible so you’re present when your property is offered. This shows serious intent to the auctioneer and bidders. Have your solicitor ready to handle contracts immediately after sale. Make sure all paperwork is in order: title deeds, building regulations certificates, energy performance certificates. Clear homes sell better, so tidy up and stage your property well during the pre-auction viewings.

Frequently Asked Questions

Can I change my reserve price after I’ve set it?
Yes, in most cases you can adjust your reserve before the auction, but it’s better to get it right from the start. Talk to your auctioneer if you want to change it. Some auction houses allow changes up to a certain deadline, while others prefer the reserve stays fixed once agreed. Always check the terms of your auction agreement.
