Selling your house at auction can be a great way to get a quick sale.
Properties at auction often sell much faster than through estate agents, and completion happens quicker too.
But before you commit, you’ll need to understand how auctions work, the costs involved and, most importantly, whether it’s the right choice for your situation.
Important note: This guide covers property auctions in England and Wales. Scotland and Northern Ireland operate under different legal systems with different auction processes.
Here’s what you need to know about auctioning your property.
What does it mean to auction a house?
A property auction is quite different from selling through an estate agent. Your house goes up for sale for a set amount of time in an environment full of competing buyers who bid against each other.
The highest bidder wins.
But here’s where it gets legally important: What happens next depends entirely on which type of auction you’re using.
Traditional (unconditional) auctions
At a traditional property auction, the sale becomes legally binding the moment the hammer falls. The winning bidder pays a 10% deposit immediately and both parties are legally committed to complete within the specified timeframe (typically 20–28 working days).
There’s no pulling out or price negotiations afterward. If the buyer does pull out, they forfeit their deposit. According to RICS Common Auction Conditions, risk in the property passes to the buyer at the fall of the hammer, meaning buyers should arrange buildings insurance immediately.
This bidding process typically takes just three to five minutes in person or via live-stream.
Did You Know?
Under RICS Common Auction Conditions, buildings insurance typically becomes the buyer’s responsibility the instant the gavel falls at a traditional auction. Risk passes to the buyer at the moment of exchange, which happens at the fall of the hammer. This means buyers remain obliged to complete even if the property is damaged between auction day and completion.

Modern Method of Auction
Modern Method of Auction (MMoA) works very differently in law.
When the “hammer falls” on a Modern Method auction, the buyer is NOT immediately bound to complete the purchase. Instead, they sign a Reservation Agreement committing to pay a non-refundable reservation fee (typically around 4.5% of the purchase price plus VAT, subject to a minimum such as £6,600 including VAT) and to use “best endeavours” to exchange contracts within 28 days.
The buyer can still withdraw before exchange. They lose their reservation fee, but they’re not legally bound to buy the property.
This format often runs over several days or even weeks (similar to eBay), giving bidders more time to discover the property and get involved. Based on what we’ve seen across our 500+ property purchases, this extended bidding window typically attracts a greater number of interested bidders, often resulting in a higher final price than the rapid-fire format of traditional auctions.
Property Rescue uses Modern Method of Auction, which gives both buyers and sellers more flexibility while still maintaining strong financial incentive to complete (the non-refundable reservation fee).
Important: Modern Method is NOT a binding contract
The Modern Method of Auction (MMA) is fundamentally different in law from a traditional unconditional auction. At a traditional auction, the gavel fall constitutes immediate exchange of contracts: the buyer is immediately bound to complete. Under MMA, the winning bid binds the buyer to pay a non-refundable reservation fee and to use “best endeavours” to exchange within 28 days, but they can still withdraw before exchange (though they forfeit the fee).
This distinction is crucial for sellers to understand: Modern Method provides strong financial incentive to complete, but not the immediate legal certainty of traditional auction.

Benefits of selling your house at auction
Auctions offer several advantages over traditional estate agent sales, particularly if you need a quick sale. Major UK auction houses now handle hundreds of millions in property sales annually. In 2024, Allsop LLP alone raised over £1 billion through its auction rooms, with its September residential auction breaking national records at £92.7 million from 371 lots.
The competitive nature of auctions can drive up prices, and if your property sells, it will do so within a relatively short timeframe. There’s no waiting around for buyers to get mortgages or hoping chains don’t break.
Key advantages:
- Sales typically complete within 28 days to 6 weeks of the auction, much faster than the average estate agent sale
- Much lower risk of sales falling through compared to traditional methods. Industry data shows that around 24% of estate agent sales fall through (with some sources citing rates as high as 30%), often after months on the market. With traditional auctions, buyers forfeit their 10% deposit if they fail to complete, creating strong financial incentive to follow through.
- Competitive bidding can push prices higher: multiple interested buyers in one place at one time
- No lengthy price negotiations or chain delays: the price is whatever the market will bear on the day
- Multiple buyers view and bid at the same time, so you’re not waiting for one buyer at a time to show interest
- Serious buyers come ready with finances in place, which is particularly important for properties requiring cash buyers or quick completion
- Deposit paid immediately by the winner (10% for traditional auctions; reservation fee for Modern Method)
Why auction buyers are more committed
Here’s the thing: auction buyers can’t just casually browse and make an offer.
For traditional auctions, buyers need their mortgage approval (if applicable) sorted BEFORE they bid. The 20–28 working day completion deadline means there’s no time for a standard mortgage application after winning the auction. This is why traditional auctions often attract cash buyers, investors and developers who can move quickly.
For Modern Method auctions, buyers still need to be serious because they’re putting down a non-refundable reservation fee the moment they win. That concentrates minds wonderfully.
From what we’ve seen over our 20+ years buying property, sellers who choose the auction route value the speed and certainty above all else. When a sale is made through traditional auction, contracts are exchanged immediately at the fall of the hammer. There’s no renegotiation period and no survey-based price chipping.
From Our Experience
We’ve completed over 500 property purchases in the last 3 years alone, with 98% of our accepted offers completing successfully. What we’ve consistently observed is that sellers value certainty almost as much as speed, and that’s exactly what auctions (and direct cash purchases) deliver.
We recently worked with a seller who had inherited a London property and tried to sell it at a traditional auction house. The property didn’t meet its reserve price at auction. After the failed auction, they came to us. We completed the purchase within 4 weeks, with no auction fees and no risk of another failed sale.
Preparing to auction your house
Before your property goes under the hammer, there’s important legal work to complete. Good preparation increases your chances of a successful sale and helps avoid any last-minute problems that could put off potential buyers.
- Choose the right auction house: Picking your auction house is one of your most important decisions. Look at their recent results, success rates and buyer database. Get quotes from several companies, as fees vary. Most auction houses charge commission of 2% to 3% plus VAT on the sale price, with entry fees typically around £300 to £400. Ask about their marketing plans and whether bidding will happen over a few minutes (traditional auction) or a number of days (Modern Method). The longer the bidding period the greater number of bids the property may attract.
- Work out the costs: You’ll need to budget for several auction costs if you go the traditional route. Entry fees range from £200 to £400 to list in the auction. Marketing packages can cost between £300 and £1,500 depending on the level of promotion. The auction house typically takes commission of 2–3% plus VAT on the final sale price. Legal pack preparation runs £500 to £1,000, and you’ll need an Energy Performance Certificate (EPC), which costs £60 to £120.
- Set your reserve price: Your reserve price is the minimum you’ll accept. If the bidding doesn’t reach this level, your property won’t sell. Work with your auctioneer to set a realistic reserve based on similar properties and recent auction results. They’ll also set a guide price, usually 10% below the reserve, to attract interest without revealing your absolute minimum.
- Get your legal pack ready: Your solicitor needs to prepare a legal pack containing title deeds, property information forms, local authority searches, and any lease documents or planning permissions. You’ll also need an Energy Performance Certificate. Make sure your legal pack is thorough and accurate, as buyers’ solicitors will check it carefully before bidding.

Critical Warning: No-Reserve Auctions
Some auction houses offer “no reserve” auctions to attract more attention. Be very careful.
Under English law, as established in Barry v Davies [2000], if you offer your property at auction without a reserve price, you are legally obliged to sell to the highest bidder no matter how low that price is. You cannot withdraw the property or refuse to sell.
In the Barry v Davies case, two brand-new engine analysers worth £14,521 each were listed without a reserve. The auctioneer refused bids of £200 per machine and withdrew them. The Court of Appeal held that offering goods without a reserve creates a binding contract to sell to the highest bona fide bidder, regardless of price.
Only agree to a no-reserve auction if you’re genuinely prepared to accept any offer, however low.
Sellers have no obligation to answer pre-auction enquiries
Here’s something most sellers don’t realise: Unlike traditional property sales where you must respond to extensive enquiries from the buyer’s solicitor, at auction you’re generally not expected to answer supplementary pre-auction enquiries beyond what’s in the legal pack.
The legal pack you provide is the information buyers get. They can ask for more, but you’re generally not obliged to respond to questions about the property’s physical condition or value. However, you must ensure the legal pack itself contains all material information buyers need to make an informed decision, in line with consumer protection requirements.
However, you do have a strict legal duty to disclose latent title defects (hidden legal problems with ownership or rights affecting the property). The principle of caveat emptor (“buyer beware”) applies to the property’s physical condition, but not to serious title issues. Deliberately concealing known legal defects or providing false information in the legal pack can lead to misrepresentation claims under the Misrepresentation Act 1967.
This is actually one of the speed advantages of auctions. No back-and-forth on questions about the neighbours’ extension or whether the garden fence is your responsibility. You provide the legal pack, buyers do their due diligence from that, and the auction proceeds.
The downside for buyers is they’re taking more risk, which is why auction buyers tend to be experienced investors who know how to assess that risk quickly.
How Property Rescue differs from traditional auctions
At Property Rescue, we offer several advantages over standard auction houses.
You won’t pay any commission or entry fees, and there are no upfront costs for legal pack preparation. Legal costs are only deducted if and when your property sells successfully.
Our process gives you more control too. You can watch bids come in live, accept early offers or close the auction early if you wish. The sale timeline is flexible to match your needs, and with a guaranteed buyer deposit system, our fall-through rate stays extremely low. We partner with established auction houses who market properties widely on major UK auction portals.
Because of our Sale and Rent Back service, we’re one of the only house buying companies in the UK that’s regulated by the FCA (register number 522471). We’ve been buying property for cash since 2005, completing over 500 purchases in the last 3 years alone.
What to expect during the auction
The auction process starts well before the actual auction. You’ll need to work closely with your auction house to make sure your property gets maximum exposure to potential buyers.
Understanding each stage helps you prepare properly and increases your chances of a successful sale.
However, if you’ve got Property Rescue on your side, your auction concierge will handle everything for you so you don’t need to stress.
Marketing your property
Your auction house will promote your property for around four to six weeks before the auction.
They’ll create a detailed listing with photos and floor plans, advertise in their auction catalogue, and list it on major property websites. They’ll also arrange viewings and open houses where multiple buyers can view before auction day.
This is where mortgage-dependent buyers do their preparation. They need to get their mortgage offer in place before bidding because there simply isn’t time to apply after winning a traditional auction. The 20–28 working day completion window won’t accommodate a standard mortgage process.
The auction: traditional format
Each property takes about three to five minutes to sell via a physical (live-streamed) traditional auction. It’s usually over before you know it.
The auctioneer starts at the opening price and buyers bid by raising their hands or bidding paddles. Online buyers can bid through live-streaming platforms or place telephone bids. The price rises until no one wants to bid higher.
When the hammer falls, that’s it. Exchange of contracts happens immediately.
The auction: Modern Method format
With Modern Method auctions, the format varies. Some are “countdown auctions” where bidding occurs within a specific timeframe (often a two-hour window), with automatic time extensions when last-minute bids come in. Many of these auctions prevent “sniping” (last-second bidding) by using a countdown format with automatic time extensions triggered by late bids.
Alternatively, other formats span several days or even weeks, giving bidders ample opportunity to discover the property and get involved. This format is similar to what eBay uses.
Typically, this extended method allows for a greater number of interested bidders, and thus results in a higher final price. Modern Method of Auction is what Property Rescue uses, so get in touch if interested in this.
Post-auction steps
If you’re using a traditional auction
Once the hammer falls, the buyer pays their 10% deposit and signs contracts immediately. They typically have 20–28 working days to complete the purchase.
If they fail to complete, they forfeit their deposit, and you can re-auction the property. However, this happens far less frequently than fall-throughs in traditional sales.
Important: Risk transfers to the buyer at the fall of the hammer under RICS Common Auction Conditions. This means if anything happens to the property between exchange and completion (fire, flood, damage), the buyer still has to complete the purchase. Buyers should arrange buildings insurance immediately upon winning the auction.
If you’re using Modern Method
The winning bidder pays the reservation fee and signs the Reservation Agreement. They then have 28 days to exchange contracts (at which point they become legally bound to complete) and a further period to complete the purchase.
During those 28 days, the buyer is using “best endeavours” to proceed but can technically still withdraw. They just lose their reservation fee if they do.
What if your property doesn’t reach reserve?
If bidding doesn’t reach your reserve price, your property remains unsold at the auction.
But that’s not necessarily the end of the road.
Most auction houses will contact the highest bidder after the auction to see if you’re willing to negotiate below your reserve. You’re under no obligation to accept, but it gives you the option.
Alternatively, you can re-auction the property (possibly with a lower reserve), try a different auction house, or switch to a different selling method entirely, such as listing with an estate agent or selling directly to a cash buyer like Property Rescue.
Common misconceptions about auctions
“Auctions are only for problem properties”
Many people believe auctions only sell run-down houses or repossessions.
Actually, all types of properties do well at auction, from family homes to luxury apartments. Recent data shows that terraced houses now account for approximately one-third of all residential auction lots, with volumes nearly 50% higher than in 2021. Semi-detached houses make up about 17% of auction stock, running roughly 75% above 2021 levels.
Sellers often choose auctions because they want a quick sale for a fair price, not because there’s something wrong with the property.
“You’ll always get less money at auction”
This needs some nuance.
It’s generally acknowledged in the industry that auction properties can sell for slightly less than they might achieve on the open market through an estate agent, with the often-cited range being around 10% to 15% below market value, though this varies significantly by property type, location and market conditions.
But here’s what most people miss: your reserve price protects you from selling too low. Since you are the one who decides the reserve price, you are in full control.
Plus, you need to factor in the total cost of ownership while selling.
For example, if you sell via an estate agent, the complete marketing and sale process might take about 6 months or longer. That’s 6 months of mortgage and maintenance costs you need to pay, on top of estate agent fees averaging 1.42% including VAT for the sale.
And what’s even more worrying is that around 24% of all estate agent sales fall through (with long-term averages showing rates as high as 30% in England), which resets the sales process back to square one, adding another 6 months to the timeframe.
With traditional auctions, withdrawal rates are far lower because pulling out means the buyer loses their deposit. With Property Rescue’s auction service, we’ve seen completion rates well above the industry average because of our guaranteed buyer deposit system.
When you factor in the cost savings gained from a quick sale (ending mortgage payments, property maintenance costs, council tax, insurance, and the opportunity cost of having your money tied up), that difference might not be such a big deal.
Based on what we’ve seen across our 500+ purchases, many sellers who include all the open-market costs (estate agent fees, any repairs needed to make property marketable, 6+ months of holding costs, mortgage interest) find their net proceeds often end up around 90–95% of market value anyway.
The auction just gets you there faster and with far more certainty.
