What gazumping actually is
Gazumping is when a seller accepts your offer, then accepts a higher offer from someone else before contracts are exchanged — leaving you out, often after you've already paid for searches, a survey and legal work. It happens because in England and Wales a sale stays "subject to contract" for the weeks between acceptance and exchange. Throughout that window, nothing is binding and either side can walk. (For the full picture, including its mirror-image, gazundering, see our guide to gazumping and gazundering.)
What the June 2026 reforms change — and what they don't
On 19 June 2026 the Ministry of Housing, Communities and Local Government announced a package of reforms designed to cut buying times by around four weeks, save first-time buyers an average of £650, and halve the number of sales that fall through. The headline measures are upfront "sales packs" at the point of listing — setting out a home's condition, leasehold costs and chain status — plus digital property logbooks, a new code of practice for estate agents, and, in time, earlier binding agreements.
That last point is the one aimed squarely at gazumping. The plan is to make a deal legally binding much earlier — potentially once an offer is accepted — with a financial penalty for any party that withdraws without a valid reason. It would be a genuine fix.
The catch is timing. The government has been explicit that binding contracts will only come after sales packs are embedded, and that the comprehensive legislation is scheduled for the end of this Parliament. A code of practice arrives later in 2026; consultation on the digital tools and agent qualifications follows from 2027. In other words, the rule that would stop gazumping is years from being in force — and until it is, you are exactly as exposed as buyers have always been.
Why you're still exposed — and what works right now
With the average purchase still taking around 120 days and roughly one in three sales falling through, the gap between offer and exchange remains long and uncertain. The way to protect yourself inside that gap hasn't changed: be the buyer who can move fastest and most credibly, so the seller has no reason to entertain anyone else.
Most of what slows a buyer down is discovering problems late — a short lease the lender won't touch, a flood zone that changes the terms, a listed-building constraint, an asking price that doesn't stack up against recent sales. Find those things before you offer and two things happen: you offer with confidence at the right number, and you remove the surprises that would otherwise stall your purchase and hand a rival their opening.
That is exactly what TrueBrick is for. For £39, a Core report pulls the public record on the specific property and reads it back in plain English — in minutes, before you commit a penny to searches or surveys.
What a TrueBrick report covers
- The asking-price read — is it fair, with comparables and price history indexed to today
- Planning & heritage constraints (listed status, conservation areas, Article 4)
- Flood, environmental and ground risk
- EPC, tenure and lease length — the things that quietly derail a sale
- Local crime profile and the seller's snapshot
- The pre-offer actions to take before you commit
TrueBrick reports are pre-offer intelligence, not legal or financial advice and not a survey or valuation. The decision is always yours, with your conveyancer and lender.
Frequently asked questions
Is gazumping illegal in the UK?
No. In England and Wales a property sale is 'subject to contract' until contracts are exchanged, which is often weeks after your offer is accepted. Until that moment either side can walk away, so a seller accepting a higher offer from someone else — gazumping — is legal. Scotland's system makes offers binding earlier and largely avoids it.
Is gazumping being banned by the 2026 reforms?
Not immediately. The government's home-buying and selling reforms, announced in June 2026, aim to curb gazumping through earlier 'binding agreements' that would carry a financial penalty for pulling out without a valid reason. But that change only comes after upfront 'sales packs' are embedded, and the comprehensive legislation is scheduled for the end of this Parliament. For the next few years, gazumping remains possible.
How can I reduce the risk of being gazumped?
Move quickly and credibly between offer and exchange — the long, non-binding window is where gazumping happens. That means having your mortgage agreement in principle ready, instructing a conveyancer fast, and doing as much due diligence as possible before you offer so nothing slows you down later. The faster and more confidently you can proceed, the less room a rival buyer has.
What are the 2026 home-buying reforms?
Announced by the Ministry of Housing, Communities and Local Government in June 2026, the reforms aim to cut buying times by around four weeks, save first-time buyers an average of £650, and halve the number of sales that fall through. Key measures include upfront 'sales packs' at the point of listing, digital property logbooks, a code of practice for estate agents, and — later — earlier binding contracts.
Will the reforms stop sales falling through?
The aim is to roughly halve fall-throughs by giving buyers key information upfront so fewer deals collapse on late surprises. Today around one in three sales falls through, costing sellers roughly £400 million a year. Until the reforms are fully in force, the best protection is to surface those surprises yourself, before you offer.
