Auction Purchases.

Properties sold at auction often have complications that make them unsuitable for the open market — which is not always obvious from the auction listing. Particular caution is warranted with: properties with very short leases or absent freeholders; properties subject to sitting tenants or occupiers with security of tenure; properties with structural problems, subsidence, or Japanese knotweed; properties with restrictive covenants that prevent development or change of use; properties on estates with management company issues or significant service charge arrears; and properties with planning enforcement notices. None of these issues prevents purchase — but they need to be identified, understood, and priced in before you bid, not discovered afterwards.

Obtaining a standard residential mortgage on an auction property is possible in principle, but the 28-day completion deadline makes it extremely difficult in practice. A formal mortgage offer requires a lender's valuation and underwriting process that typically takes longer than 28 days to arrange from scratch. Most auction buyers — particularly for properties needing work — use bridging finance to complete within the required timeframe and then refinance onto a standard mortgage once the property is in a mortgageable condition. If you intend to use a mortgage, speak to a broker before the auction to understand what is available and how quickly an offer could be issued. Relying on a mortgage you have not yet secured before bidding is a significant financial risk.

At a traditional auction, no — pulling out after the hammer falls means you are in breach of contract. The consequences are serious: you forfeit your full deposit, the seller can remarket the property, and if it sells for less than your bid, the seller can pursue you for the difference plus their costs. In practice, litigation over auction defaults does occur. Under the modern method of auction, you can withdraw after paying the reservation fee — but the reservation fee is non-refundable. The only scenario in which a buyer might successfully rescind an auction contract is if the seller has misrepresented the property or there is a fundamental defect in title that was not disclosed — but these are narrow grounds and require legal advice immediately.

Buying at auction is fundamentally different from a standard property purchase in one critical respect: exchange of contracts happens in the auction room the moment the hammer falls. There is no negotiation period, no cooling off, and no ability to withdraw without losing your deposit and facing further liability. All legal due diligence — reviewing the legal pack, checking title, raising any concerns — must be completed before you bid, not after. Completion typically follows within 28 days. The speed and commitment involved make auction purchases higher risk than standard purchases, but they can offer genuine value — particularly for properties that need work or have complications that deter mainstream buyers.

Traditional auctions typically require completion within 28 days of the auction date — this is set out in the special conditions of the contract in the legal pack and is not negotiable. Some contracts specify a shorter period. The modern method of auction usually allows a longer period — typically 56 days — but involves an initial reservation fee and exchange within 28 days, with a further period to complete. The fixed completion deadline is one of the most challenging aspects of auction purchases: arranging finance, carrying out any remaining checks, and completing the legal work all has to happen within that window. Missing the completion deadline has serious financial consequences.

At a traditional auction, you will be required to pay a deposit — typically 10% of the purchase price — on the day, immediately after the hammer falls. You must have this available in cleared funds; a personal cheque may not be accepted. The deposit is non-refundable if you fail to complete. Some auctions accept a lower deposit in certain circumstances, but 10% is the standard. For the modern method of auction, a reservation fee — usually a fixed amount or a percentage of the purchase price — is paid upfront to secure the property, followed by the contract deposit on exchange. Budget for the deposit as part of your total auction costs before you bid.

Beyond the purchase price and deposit, auction buyers should budget for: a buyer's premium or administration fee charged by the auctioneer — typically 1.5% to 2.5% plus VAT on top of the purchase price; stamp duty land tax or land transaction tax on the full purchase price; solicitor's fees for reviewing the legal pack and handling the purchase; search fees if searches are needed rather than search insurance; survey or structural inspection costs; and any remedial works if the property needs renovation. For properties purchased with bridging finance, arrangement fees and monthly interest must also be factored in. The true cost of an auction purchase is frequently higher than the hammer price — budgeting carefully before you bid is essential.

Buying at auction without having the legal pack reviewed by a solicitor beforehand is one of the highest-risk decisions a property buyer can make. Issues that a solicitor would identify — restrictive covenants, defective title, short leases, missing planning consents, unusual contract conditions, or occupancy complications — become your problem the moment the hammer falls. There is no recourse against the seller for issues that were in the legal pack, even if you did not read it. Beyond the legal pack, structural issues, Japanese knotweed, and access problems may not be visible on a brief inspection. The cost of a solicitor reviewing the pack before auction is modest compared to the cost of being legally bound to purchase a property with a serious undiscovered problem.

Yes — at a traditional property auction, the fall of the hammer constitutes exchange of contracts. You are immediately and legally bound to purchase the property on the terms of the contract in the legal pack, at the price you bid. There is no cooling-off period, no ability to withdraw, and no further negotiation. You must pay the deposit — usually 10% of the purchase price — on the day, and complete within the timeframe set out in the contract, typically 28 days. If you fail to complete, you forfeit your deposit and the seller can pursue you for any further losses. This is why all due diligence must happen before the auction, not after — there is no opportunity to change your mind once you have won the bid.

A legal pack is the bundle of documents prepared by the seller's solicitor and made available to prospective bidders before the auction. It typically contains: official copies of the title register and plan from HM Land Registry; the draft contract and special conditions of sale; any searches already obtained by the seller; relevant planning documents; tenancy agreements where the property is occupied; management information for leasehold properties; and any other documents affecting the title. The legal pack replaces the pre-contract enquiry process that takes place in a standard purchase — which is why reviewing it carefully before bidding, with legal advice, is so important. Packs vary in quality and completeness; gaps or unusual conditions are red flags.

The modern method of auction (MMoA) — also called conditional auction — is an online auction format that differs from traditional auction in its legal structure and timeframes. Rather than exchanging contracts immediately on the fall of the hammer, the winning bidder pays a non-refundable reservation fee and enters a reservation agreement giving them an exclusivity period — typically 28 days — in which to exchange contracts, followed by a further period of around 28 days to complete. This longer timeline makes it possible to arrange a mortgage, but the reservation fee is lost if you do not proceed. The legal pack should still be reviewed before bidding. MMoA has become increasingly common with online auction platforms, and buyers should understand which format they are entering before bidding.

Before bidding, your solicitor should review the legal pack in full, check the title at HM Land Registry, consider whether searches are needed or whether search insurance is appropriate, review any tenancy agreements or occupancy arrangements, check for any restrictions, covenants, or easements affecting the property, and flag any issues that might affect value, mortgageability, or your ability to use the property as intended. Planning history should also be checked, particularly for properties with extensions or changes of use. Any queries should be raised with the seller's solicitor before the auction — once the hammer falls, you take the property as it is, with all its legal baggage. Bidding without legal advice on the pack is a significant risk.
