Quick definition
Gazumping is when a seller accepts one buyer’s offer for a property and, before exchange of contracts, accepts a higher or more attractive offer from another buyer. In England and Wales it is generally lawful because the accepted offer is usually subject to contract until contracts satisfying the Law of Property (Miscellaneous Provisions) Act 1989 section 2 are exchanged; Scotland uses missives, so risk is usually lower after conclusion.
Characteristics
Gazumping is not defined as a standalone statutory offence in England and Wales. Its practical legality comes from the pre-exchange structure of residential conveyancing: an accepted offer is normally made “subject to contract”, and GOV.UK and the Law Society both distinguish that stage from exchange. The disappointed buyer may lose survey, mortgage and legal costs, while the seller may risk delay, reputation damage and chain collapse.
| Attribute | Detail |
|---|---|
| Core act | Seller accepts a later, better or safer offer after already accepting another buyer’s offer. |
| Legal basis | No statutory definition; the risk exists because the sale is not binding before exchange in England and Wales. |
| Affected party | The first buyer, and often the connected chain. |
| Typical trigger | Higher price, cash buyer, chain-free buyer, faster exchange or seller anxiety over delay. |
| Protection | Fast conveyancing, seller removing marketing, reservation agreements and properly drafted lock-out agreements. |
| Case law note | Pitt v PHH Asset Management Ltd shows a time-limited lock-out agreement can be enforceable separately from the land sale. |
| What it is not | It is not the same as gazundering, where the buyer lowers the price. |
| UK variation | Scotland’s missives can bind earlier once concluded; Northern Ireland still identifies exchange as the binding point. |
Examples
A buyer in south London may have an offer accepted on a Victorian terrace, pay for a survey and ask a solicitor to start searches. If another buyer then offers a higher price before exchange and the seller accepts, the first buyer has been gazumped. The first buyer may have spent money, but there is usually no completed sale contract to enforce.
In Bristol, gazumping can also happen when a chain-free cash buyer appears after a mortgage buyer has already received a memorandum of sale. The seller may prefer speed and certainty, not only a higher figure. In Edinburgh, the risk profile is different because solicitors work through missives and mygov.scot says the concluding missive is binding. In Belfast, nidirect still identifies exchange of contracts as the point where the sale becomes legally binding, so pre-exchange risk remains.
Common misconceptions
- Gazumping is not automatically illegal in England and Wales. It may feel unfair, but the accepted offer is usually not binding until exchange.
- A Sold STC board does not prevent gazumping. It shows a sale agreed in principle, not a completed transfer or an exchange of contracts.
- A memorandum of sale does not guarantee exclusivity. Buyers who want exclusivity need a separate agreement, and the drafting must be handled carefully.
- Scotland is not identical to England and Wales. Gazumping can theoretically occur before missives conclude, but once the concluding missive exists, the Scottish process creates a binding contract.
- A lock-out agreement is not a promise to sell. Pitt v PHH treated it as a negative undertaking not to deal with others for a specified period, with damages as the remedy if breached.
