Can you make an offer before auction day?

Yes — making a pre-auction offer is possible, and it is more common than many buyers realise. If you have spotted a property in an upcoming auction catalogue and do not want to risk losing it to competitive bidding on the day, approaching the auction house with an offer before the sale is a legitimate route. But it comes with strict conditions, significant legal implications, and no guarantee the seller will accept.

This guide explains exactly how the pre-auction offer process works, what you need to have in place before approaching the auction house, when sellers are likely to accept and when they will not, and the legal steps that follow if your offer is agreed.

What is a pre-auction offer and how does it work?

A pre-auction offer is a formal offer made to the seller of a property that has been listed for auction, submitted before the scheduled auction date. The process is handled through the auction house — not directly with the seller. Most reputable auction houses in the UK are obliged to present all genuine offers to their seller clients, regardless of whether the offer is below, at, or above the guide price.

If the seller accepts, the purchase proceeds under auction rules. That means contracts exchange immediately — typically within 24 hours of acceptance — and a deposit (usually 10% of the agreed price) is paid on exchange. Completion then follows within the standard auction timeframe, which is normally 20 to 28 working days.

In other words, a successful pre-auction offer carries the same legal weight and timeline as winning a bid on auction day. There is no ‘subject to contract’ period, no cooling-off, and no ability to renegotiate once the offer is accepted and contracts are exchanged. This is one of the most important things to understand before making an approach.

Why would a buyer want to make a pre-auction offer?

The most common reason is competitive anxiety. If a property is attracting significant interest before auction day — many viewings, high numbers of auction legal pack downloads, strong interest from multiple parties — a buyer who has done their research may prefer to lock in the purchase at an agreed price rather than risk being outbid on the day.

There are other situations where a pre-auction offer makes sense:

  • You have a tight timeline and need to exchange quickly, which an early agreement can facilitate.
  • The property is unusual or niche — where you have reason to believe interest may be stronger than the guide price suggests.
  • You want certainty — particularly if you are a cash buyer or have bridging finance already in place and want to remove the uncertainty of auction day competition.

The trade-off is that a strong pre-auction offer will almost always need to be at or above the guide price. You are not going to secure a pre-auction deal at a discount relative to what you might pay on the day — in fact, the opposite is usually true.

Why some sellers will not accept pre-auction offers

Not every property listed at auction can be sold before the hammer falls. There are several scenarios where a pre-auction offer will simply not be considered, regardless of the price.

Some sellers enter into exclusive marketing agreements with the auction house that prohibit early sales. The auction house has a commercial interest in taking properties through to the room, and some contracts reflect this.

Probate sales are a common example where a pre-auction offer may be inappropriate or even legally problematic. When a property is being sold by executors on behalf of a deceased estate, the executors have a duty to achieve the best available price. Accepting a pre-auction offer could expose them to a challenge from beneficiaries if the sale is later argued to have been below market value — particularly without the evidence of competitive bidding to support the price achieved.

Other sellers are simply focused on price maximisation and do not want to forgo the competitive dynamic that auction day bidding can create. If a property has strong interest from multiple parties, a seller may rationally decline even a very attractive pre-auction offer on the basis that auction day competition could drive the price higher still.

How much should a pre-auction offer be?

Your pre-auction offer will need to be compelling enough to persuade the seller to forgo the prospect of competitive bidding. As a general rule, any offer below the guide price is unlikely to be taken seriously.

Guide prices in property auctions are indicative figures — they represent the lower end of what the seller expects, not a ceiling on what the property might achieve. A property with a guide price of £150,000 may sell for £175,000 or more on auction day if multiple bidders are competing. Your pre-auction offer needs to reflect the risk you are asking the seller to absorb by removing the property from competition.

In practice, a pre-auction offer at or slightly above the guide price may be sufficient where interest is low or the seller has a time-sensitive motivation to complete. Where a property is attracting strong pre-auction interest, you may need to offer materially above the guide to tempt the seller away from the room.

There is no universally correct figure. The auction house will give you an indication of likely interest levels, and a specialist solicitor who has reviewed the auction legal pack can advise on whether the guide price reflects genuine market value or whether there are issues in the legal documents that might affect what the property is worth.

Thinking about making a pre-auction offer?

Before you approach the auction house, you need to understand exactly what you are committing to. The auction legal pack review service from AuctionSolicitor gives you a thorough assessment of the legal pack — including title, special conditions, searches, and any risks — so you know what you are taking on before exchange becomes binding. Contact us to discuss your timeline and we will review the pack ahead of your offer.

The legal pack: why you must read it before making any offer

Buying property at auction — whether pre-auction or on the day — is legally binding from the moment exchange takes place. There is no withdrawal right, no survey contingency, and no opportunity to renegotiate. This makes the auction legal pack not just useful to read before bidding, but essential.

The auction legal pack contains the title deeds and office copies, the special conditions of sale (which override the standard auction terms), any searches that have been obtained, the energy performance certificate, tenancy information where applicable, and any other documentation the seller’s solicitor has chosen to include.

Reviewing the auction legal pack before making a pre-auction offer is especially important because some properties are listed at auction precisely because they have legal complications — short leases, title defects, onerous covenants, missing consents, or enforcement notices — that would make a standard estate agent sale difficult or impossible. Our detailed guide on what is in an auction legal pack covers everything buyers need to check.

A buyer who makes a pre-auction offer without a solicitor reviewing the legal pack first is taking on unknown legal commitments with no ability to pull back once the offer is accepted. This is one of the most significant risks in the entire buying-at-auction process.

What happens after a pre-auction offer is accepted?

Once the auction house has presented your offer to the seller and the seller has agreed, the process moves quickly. The transaction follows auction rules from this point forward:

  • Contracts are exchanged within 24 hours of acceptance in most cases.
  • A deposit — usually 10% of the agreed purchase price — is paid on exchange.
  • The buyer’s and seller’s solicitors complete the legal formalities within the standard 20 to 28 working day completion window.
  • The property is simultaneously withdrawn from the auction listing.

There is no chain, no gazumping, and no ability for the seller to accept a higher offer once exchange has taken place. The certainty is one of the genuine advantages of buying property at auction — it applies equally to a pre-auction sale.

Before exchange takes place, your solicitor will need to have raised and resolved any enquiries arising from the auction legal pack, confirmed the title position, and advised you on the special conditions of sale. This work needs to be completed before exchange — not after — because there is no opportunity to renegotiate once contracts are signed.

AuctionSolicitor specialises in exactly this kind of deadline-led conveyancing. Our buying at auction service is designed to work within tight auction timelines, whether you are completing after a pre-auction offer or after the hammer falls on the day.

How to submit a pre-auction offer: a step-by-step guide

If you have reviewed the legal pack, taken legal advice, and are ready to proceed, here is the practical process for making a pre-auction offer:

  • Instruct a solicitor first. Have the auction legal pack reviewed before you approach the auction house. You need to know what you are committing to.
  • Confirm your finances. Whether you are using cash, bridging finance, or a mortgage (where the timeline allows), you need to be able to demonstrate immediately available funds. Proof of funds is almost always required alongside any formal offer.
  • Contact the auction house, not the seller. Any offer must go through the auction house. Approaching the seller directly is discouraged, often prohibited by the seller’s contract, and may undermine your credibility as a buyer.
  • Submit a formal written offer. Include your proposed price, confirmation of the basis on which you are purchasing (cash, bridging loan, etc.), proof of identity and funds, and a statement that you are ready to exchange promptly.
  • Act quickly on acceptance. If the seller accepts, you will be expected to exchange within 24 hours in most cases. Your solicitor needs to be ready to move at short notice.

Pre-auction offers on conditional auction properties

It is worth distinguishing between unconditional and conditional (modern method of) auction when considering pre-auction offers.

In an unconditional auction — the traditional model used by most specialist property auction houses — exchange takes place on auction day itself. If a pre-auction offer is accepted, exchange similarly takes place immediately, with the same binding effect.

Conditional auctions operate differently. The buyer pays a reservation fee and enters into a conditional agreement that allows a period of typically 28 to 56 days for legal and financial due diligence before exchange. A pre-auction offer on a conditional lot may therefore carry somewhat less immediate risk — but the reservation fee is non-refundable, and the legal pack still needs careful scrutiny before any commitment is made.

If you are unsure which type of auction applies to a property you are interested in, our guide on buying property at auction covers both formats in detail, and our team can advise before you approach the auction house with an offer.
