What is Gazumping?

Gazumping Definition

Gazumping occurs when a seller accepts a higher offer from a different buyer after already having verbally agreed to sell to someone else. It typically happens in the period between an offer being accepted and exchange of contracts - a window that can last 8–12 weeks or more in England and Wales.

The original buyer loses the property and, crucially, any money already spent on surveys, solicitors' fees, and mortgage arrangement fees - which can total £1,000–£3,000 or more.

Why Gazumping Happens

Gazumping is a consequence of the English and Welsh conveyancing system, where a property sale is not legally binding until exchange of contracts. Key factors:

• No legal commitment: A verbal agreement to sell has no legal force
• Slow conveyancing: The weeks between offer acceptance and exchange create a vulnerability window
• Rising markets: Gazumping is most common in hot markets where demand exceeds supply and prices are rising
• Estate agent incentives: Agents earn commission based on the sale price, so a higher offer benefits them financially
• Cash buyers: A cash buyer who can complete quickly may be more attractive than a buyer relying on a mortgage, even at a lower price

How to Protect Yourself

• Get a mortgage agreement in principle: Shows the seller you are a serious, qualified buyer
• Instruct a solicitor immediately: Have your conveyancer ready to go the moment your offer is accepted
• Request the property is taken off the market: Ask the seller to stop viewings once they accept your offer
• Move quickly: Respond promptly to all requests from your solicitor and mortgage lender
• Consider a lock-out agreement: A short-term legal agreement (typically 2–4 weeks) preventing the seller from accepting other offers while you proceed with due diligence
• Home buyers' protection insurance: Covers your wasted survey, legal and mortgage fees if the sale falls through due to gazumping
• Build rapport with the seller: Where possible, deal directly with the seller - they are less likely to gazump a buyer they have a personal connection with

Gazumping in Scotland

Scotland has a different conveyancing system that largely prevents gazumping. In Scotland, once a seller accepts a formal written offer (a "missive"), the agreement becomes legally binding. This means the seller cannot accept a higher offer from another buyer.

The Scottish sealed-bid system, where buyers submit their best offers by a deadline and the seller chooses, also reduces the opportunity for gazumping.

Gazundering

The opposite of gazumping, gazundering occurs when a buyer lowers their offer just before exchange of contracts, knowing the seller may feel pressured to accept rather than restart the process. Gazundering is more common in falling markets and can be equally frustrating for sellers who have already invested time and money in the transaction.
