What Is Gazumping and How Can You Protect Yourself? (UK 2025 Guide)

What Is Gazumping?

In the UK housing market gazumping happens when a seller accepts a higher offer from another buyer after already agreeing to sell to you —usually before contracts are exchanged.

You might think you’ve secured the property after your offer is accepted. But in England and Wales that agreement isn’t legally binding until contracts are exchanged. That’s where gazumping can strike—and it’s both financially and emotionally draining.

Why Is Gazumping Still Legal in the UK?

Despite being seen as unethical gazumping is still legal in England and Wales because a verbal agreement to buy a property doesn’t have legal weight. Only the formal exchange of contracts creates a binding commitment.

This means sellers can:

• Accept a higher offer at any time before exchange

• Use a higher offer to pressure existing buyers to raise theirs

• Back out of the agreed sale with little consequence

In Scotland this is not allowed. Once an offer is accepted in writing the deal becomes legally binding much earlier which significantly reduces gazumping.

How Gazumping Can Cost You

Being gazumped can result in significant losses including:

• Survey and valuation fees (typically £400–£1 000)

• Solicitor’s fees for legal checks already started

• Time and stress especially in a competitive market

You may also have missed out on other homes while waiting for this deal to proceed.

Is Gazumping Common in 2025?

While the property market cooled slightly in 2023–2024 gazumping remains common in high-demand areas such as:

• London and the South East

• Birmingham Manchester and other growing cities

• Locations with limited housing stock

Low supply + high demand = more bidding wars = more gazumping.

7 Ways to Protect Yourself from Gazumping in the UK

1. Ask for the Property to Be Taken Off the Market

The moment your offer is accepted ask the seller (via their estate agent) to remove the property from online listings . This discourages further interest and new offers.

Pro tip: Get confirmation in writing.

3. Use a Lock-Out Agreement

Also called an exclusivity agreement this is a legal contract where:

• The seller agrees not to negotiate with other buyers

• For a fixed time (e.g. 2–4 weeks) only you can buy the home

You’ll need both parties to sign it and may incur solicitor fees—but it adds protection.

---

4. Consider Gazumping Insurance

Some specialist insurers offer home buyer protection insurance which can:

• Cover costs lost due to gazumping (e.g. legal fees survey costs)

• Typically costs between £50–£75

It won’t stop gazumping—but it cushions the financial blow.

---

5. Maintain Open Communication

Stay in close contact with the estate agent and seller . Regular updates help:

• Show you’re serious and ready to move

• Spot early signs if they’re getting cold feet

---

6. Don’t Reveal Your Budget

If the seller or estate agent knows you can pay more they may invite a bidding war. Keep your maximum budget private —only reveal what’s needed to win the property.

---

7. Have a Backup Plan

If the seller starts acting suspiciously (delays vague responses) start viewing other properties again . Don’t let hope blind you to warning signs.

---

Should the Law Change?

Many experts argue that gazumping is unfair and outdated. Some proposed changes include:

• Making accepted offers legally binding earlier

• Mandatory reservation agreements

• Penalising sellers who back out without good reason

Until those changes happen buyers need to protect themselves proactively.
