A land auction sells your land on a fixed date to the highest bidder at or above a minimum price you set in private. In England and Wales, at a traditional auction the contract is made on the fall of the hammer: the buyer pays a deposit on the spot and must complete on a set date, usually 20 business days later.
The weeks before auction day are spent making that binding moment safe for both sides. You instruct an auctioneer, your solicitor prepares the legal pack, the auctioneer markets the lot with a guide price, and bidders do their checks before they bid, because once the hammer falls they cannot back out.
What are the steps in selling land at auction?
Here is the sequence for a traditional (unconditional) auction in England and Wales, as of September 2026. Timings for completion come from the RICS Common Auction Conditions and the RICS consumer guide to property auctions. Timings before auction day depend on the auctioneer's catalogue dates.
| Step | What happens | Typical timing |
|---|---|---|
| 1. Instruct the auctioneer | Agree terms of appointment, fees, guide and reserve approach. ID and anti-money-laundering checks on you. | Before marketing starts |
| 2. Instruct a solicitor | Solicitor prepares the legal pack and special conditions of sale. | Alongside step 1 |
| 3. Catalogue and marketing | Lot listed with a guide price. Viewings, legal pack online, bidders register. | A month is possible for a simple lot |
| 4. Reserve confirmed | You agree the reserve in writing, and it can be fixed just before the lot is offered. | Up to auction day |
| 5. Auction day | Hammer falls, sale memorandum signed, buyer pays deposit. | Day 0 |
| 6. Completion | Buyer pays the balance, you receive the money and hand over the land. | 20 business days after the auction unless the special conditions say otherwise |
| 7. Tax | Capital gains tax falls in the tax year of auction day. Any residential element needs a 60-day return if tax is due. | From completion |
Step 1: instruct an auctioneer
An auctioneer selling land is an estate agent in law. The Estate Agents Act 1979 applies to anyone who, as a business, introduces a buyer to a client selling an interest in land, and it has no exemption for auctions. Under section 18, the auctioneer must tell you in writing, before you're committed, what you'll pay, when it becomes payable, and any other charges.
The RICS consumer guide says the terms of appointment should cover commission if the lot sells at auction, if it's withdrawn or sold before the auction, and if it sells after the auction, whoever finds the buyer. It should also set out any extra charges and any fees the auctioneer will ask the buyer to pay. The cost of selling land at auction breaks these fees down.
Auctioneers selling land or property are "estate agency businesses" under the Money Laundering Regulations 2017. HMRC's anti-money-laundering guidance for estate agents says the checks on a seller must be completed when the agreement to list the land is made. Expect to provide ID for yourself and for the legal owner, if that isn't you. For a company, trust, or estate, that means the people behind it too.
Step 2: instruct a solicitor and build the legal pack
Bidders at a traditional auction commit before they can ask questions the way a private-treaty buyer would, so the legal pack does the answering in advance. Your solicitor usually prepares:
- the special conditions of sale, which set the terms specific to your lot, such as completion date, overage, and rights reserved
- official copies of the title register and title plan
- searches, if you choose to provide them
- replies to pre-contract enquiries
- tenancy agreements, grazing licences, and any notices served
- an Energy Performance Certificate if the lot includes a dwelling
The RICS professional standard for auctioneers says the special conditions should, at a minimum, give a title number and say whether the sale is subject to any tenancies. If your land is unregistered, sale triggers compulsory first registration, and registering beforehand makes the pack easier to read: see registering unregistered agricultural land.
Step 3: guide price and marketing
The auctioneer publishes a guide price with the catalogue, and marketing runs until auction day. HomeOwners Alliance's guide to selling at auction says a property can go up for auction within a month. Land with tenancies, access questions, or missing title documents can take longer to get ready, because the pack has to be finished before bidders will take the lot seriously.
The guide price is not a free choice. Since the Advertising Standards Authority's 2014 ruling, auctioneers must explain in their ads that the guide is an indication of the range the minimum sale price falls within, or, for a single figure, within 10% of it, unless they update the guide whenever the reserve goes above it. See auction reserve price and guide price for how that limits your reserve.
Since 6 April 2025, the Digital Markets, Competition and Consumers Act 2024 has governed misleading marketing, replacing the Consumer Protection from Unfair Trading Regulations 2008. National Trading Standards withdrew its Parts A, B, and C material information guidance in May 2025, as Propertymark reported, but the duty not to leave out information a buyer needs still applies. For land, that includes tenancies, rights of way, restrictive covenants, flood risk, and overage.
Step 4: set the reserve
The reserve is the lowest price the auctioneer may sell at. Under the RICS professional standard it's confirmed when you instruct the auctioneer or, if the auctioneer agrees, at any time before the lot is offered. It stays confidential between you and the auctioneer. Under the Common Auction Conditions every lot is subject to a reserve unless the catalogue says otherwise.
What happens on auction day?
Auctions for land run in three formats, and the legal effect of the hammer is the same in each.
| Format | How bidding works | When the contract is made |
|---|---|---|
| Room auction | Auctioneer on a rostrum, with bids from the room plus proxy, telephone, and online bids | On the fall of the hammer |
| Live-streamed auction | Auctioneer on a rostrum, bidders take part remotely | On the fall of the hammer |
| Online timed auction | Bidding on a platform with a set closing time, which can be extended by late bids | When the timer ends and the auctioneer accepts the top bid |
For more on the third format, see online land auctions in the UK. Whichever format you choose, selling land at auction starts with the same paperwork.
When bidding reaches your reserve, the auctioneer can sell. Under the RICS Common Auction Conditions (5th edition, July 2024), the successful bidder must, before leaving:
- give the information needed to complete the sale memorandum, including proof of identity
- sign the sale memorandum
- pay the deposit, which is the greater of 10% of the price (excluding VAT) and any minimum deposit the auctioneer sets
If the buyer doesn't sign or pay, the auctioneer can treat that as the buyer repudiating the contract and offer the lot again, and you may have a claim against the buyer for breach.
Where the auction conditions reserve a right for the seller to bid, the seller, or the auctioneer on the seller's behalf, can bid up to but not at or above the reserve. The Sale of Land by Auction Act 1867 requires the particulars or conditions to say whether land is sold with a reserve or with a right to bid. If land is advertised as sold without reserve, the seller may not bid at all.
What happens after the hammer falls?
At a traditional auction you now have an exchanged contract. The deposit is usually held by the auctioneer, and under the Common Auction Conditions it's held as stakeholder unless the sale conditions say it's held as agent for the seller.
Completion takes place on the date in your special conditions, or 20 business days after the auction if none is given. Insurance risk generally passes to the buyer when the hammer falls, as the RICS consumer guide notes. If either side isn't ready on the day, the other can serve a notice to complete, which gives 10 business days and makes time of the essence. If the buyer then fails to complete, you can end the contract, keep the deposit, resell the land, and claim damages.
For tax, section 28 of the Taxation of Chargeable Gains Act 1992 sets the disposal date as the date the contract is made, not the date of completion. At a traditional auction that's auction day, so an auction on 2 April and completion in May puts the gain in the tax year ending 5 April. If the sale includes a house or cottage and there's capital gains tax to pay, HMRC requires a return and payment within 60 days of completion for the residential part. Talk to your accountant before you pick an auction date.
How is a conditional auction different?
At a conditional auction, often sold as the "modern method of auction", the hammer doesn't create a binding contract. The RICS consumer guide describes it as the winning bidder buying an option to exchange contracts at the hammer price within a set period, usually four weeks after the auction. The buyer pays a non-refundable reservation fee on top of the price, rather than a 10% deposit on the day, and the fee doesn't count towards what you receive.
For you, that means more time for the buyer to arrange a mortgage and search, and a less certain result than a traditional auction. Under The Property Ombudsman's code for residential estate agents (paragraph 4a), an agent recommending a method of sale must explain its potential benefits and disadvantages. One disadvantage the Ombudsman has pointed to is that buyers may lower their bids to allow for the fee. For CGT, the disposal date moves to when contracts actually exchange. Traditional auction vs modern method of auction compares the two.
What if the land doesn't sell?
If bidding stops below your reserve, the auctioneer should say the lot is unsold, not bring the hammer down, and not suggest bidding has reached the reserve. The lot is withdrawn.
A withdrawn lot can still sell. The RICS consumer guide says the auctioneer will usually try to sell the lot at the reserve or higher after the auction, under your terms of appointment. Bidders who stopped short, and people who watched without bidding, can still make offers after the auction. A post-auction sale is usually agreed on the same auction contract, with exchange through the solicitors under the Law Society's formulae, so the buyer is still bound once exchange happens.
Before you accept, check three things:
- what commission your terms charge on a post-auction sale, and for how long after the auction that applies
- whether the buyer is taking on the same completion date and deposit as auction bidders
- whether lowering your price means relisting with a new guide, because the guide-price rules apply to the next auction too
What does a farm or rural lot add?
Land brings questions a house doesn't. The main ones to settle before the catalogue goes out:
- Tenancies. Land let on an Agricultural Holdings Act 1986 tenancy or a Farm Business Tenancy is sold subject to it. Put the agreement, the rent, and any notices in the pack. See selling agricultural land with tenants.
- Scheme agreements. Under the SFI26 scheme rules in England, you must tell the Rural Payments Agency in writing when you lose management control of land. The RPA will not usually transfer the agreement to the buyer, and you may have to repay payments for that year.
- Delinked payments. In England, delinked payments are not attached to land, so a sale doesn't pass them to the buyer. In Scotland, payment entitlements still exist and are transferred separately, following the Rural Payments and Services transfer guidance.
- Overage, sporting, and mineral rights. Anything you want to keep, such as a share of future development value, shooting rights, or mines and minerals, must be written into the special conditions before the auction.
- VAT. Land sales are normally exempt from VAT, but if you or a previous owner opted to tax the land, the sale may be standard-rated. Your solicitor needs to say so in the pack, because bids are made excluding VAT.
Executors should note that GOV.UK advises against putting property on the market before the grant of probate. With completion 20 business days after the hammer, the grant needs to be in hand. A whole farm adds lotting, farmhouse, and holdover questions on top of these.
How do land auctions work in Scotland?
Scotland has its own property law, so a Scottish land auction runs on different documents and terms.
- Terms. The auctioneer is known as the judge of the roup, and the conditions of sale are the articles of roup, as the RICS consumer guide notes. The Sale Conditions in the RICS Common Auction Conditions apply only to property in England and Wales, and the Sale of Land by Auction Act 1867 does not extend to Scotland.
- Contract. A Scottish property sale is normally concluded by missives, an exchange of letters between solicitors. At a Scottish auction, the successful bidder usually signs a minute of preference and enactment on auction day, which binds them under the articles of roup. Both sides need a solicitor qualified in Scots law.
- Home Report. Houses marketed for sale in Scotland normally need a Home Report. The Trading Standards Business Companion guidance says mixed sales are exempt when the house and non-residential property will clearly be sold together, such as a farmhouse with its farm buildings. An EPC is still needed for a dwelling.
- Title. Land still recorded in the General Register of Sasines moves onto the Land Register of Scotland when it's sold for value.
- Tax. The buyer pays Land and Buildings Transaction Tax to Revenue Scotland, not SDLT. Capital gains tax for the seller is UK-wide and follows the same rates and rules.
In Wales, the Common Auction Conditions and the 1867 Act apply as in England. The buyer pays Land Transaction Tax to the Welsh Revenue Authority instead of SDLT.
Next steps
- Get your title in order: official copies, plans, and first registration if the land is unregistered.
- Gather the paperwork a bidder will ask for: tenancies, scheme agreements, access rights, and any overage or reservations you want.
- Ask your accountant how the auction date affects capital gains tax, and whether VAT applies.
- Ask a RICS-registered valuer what the land is worth, so you can judge the guide and reserve an auctioneer proposes.
- Compare auctioneers' terms of appointment, including fees for no sale, withdrawal, and post-auction sale.
