Government Plans to End Gazumping With Binding Contracts in House Sale Shake-Up
The government has announced sweeping reforms to the home buying system in England and Wales, including legally binding sales agreements and mandatory upfront property information packs designed to end the practice of gazumping once and for all.
Housing Secretary Steve Reed confirmed the plans on Friday, saying the changes will make the system "faster, fairer and more secure" by introducing binding conditional contracts much earlier in the home buying process — potentially as soon as an offer is accepted. If a buyer or seller withdraws without a valid reason, they will face a financial penalty.
Prime Minister Sir Keir Starmer said the current system leaves "people in limbo" and puts home ownership out of reach for some. "We're turning the page. Our reforms will bring this outdated process into the modern age, saving people time and money, and giving them the certainty they deserve," he said.
For UK property investors, the reforms are a double-edged sword. Binding contracts reduce the risk of deals collapsing at the last minute — a frustration that costs the industry millions each year. But the 2029 implementation timeline means nobody should hold their breath, and the new sales pack requirements could initially slow down how quickly properties reach the market.
This article breaks down exactly what the government has announced, how it compares to Scotland's existing system, and what it means for property investors, landlords and deal sourcers in the current market.
What the new binding contracts mean for home buyers and sellers
At the heart of the reforms is a simple structural change: making property sale agreements legally binding much earlier in the process. Under the current system in England and Wales, a buyer and seller may agree on a sale only for the seller to pull out weeks or months later because someone has offered a higher price. For the gazumped buyer, there is currently no legal recourse. The same applies to buyers who change their mind after the seller has taken the property off the market — the seller is left to start over.
The government's proposal introduces binding conditional contracts that would make a transaction legally binding much earlier — potentially from the point an offer is formally accepted. If a party breaks that agreement by withdrawing without a valid reason or not meeting their obligations, they would face a financial penalty.
The system mirrors what already exists in Scotland, where formally accepted offers are legally binding once solicitors have exchanged letters (known as "missives"). If either party withdraws, they are liable for the other party's financial losses. The Scottish model also requires sellers to provide home surveys to prospective buyers upfront — something the new English and Welsh reforms will adopt through mandatory "sales packs."
The sales pack requirement is a crucial element. Sellers and estate agents will be required to share important information about the property — including its condition and position in a chain — before a sale can proceed. The government says binding contracts will not come into force until the sales packs are also active, ensuring buyers have the key information they need before committing.
Rightmove data shows it takes an average of nearly six months (170 days) to complete a property sale across the UK, and more than one in five sales initially fall through. The reforms target both problems: reducing fall-throughs and speeding up completions.
The £650 saving claim — and the catch
The government estimates buyers will save about £650 on average under the new system. This figure reflects the typical abortive costs — legal fees, survey costs and valuation fees — that a buyer incurs when a sale falls through late in the process.
For property investors who conduct thorough due diligence before every acquisition, the savings could be even greater. A full building survey, environmental searches, lender valuation and legal work can easily run to £1,500-£2,500. Having a sale fall through after incurring these costs is a direct hit to a deal sourcer's margin.
However, there is a catch. The same experts who welcome the reforms have also raised concerns about unintended consequences. If sellers must prepare comprehensive sales packs before listing a property, some may take longer to bring homes to market. This could temporarily reduce the supply of new listings — and in a market where supply is already constrained, that could push prices higher in the near term.
There are echoes here of the Home Information Packs (HIPs) introduced by the previous Labour government in 2007 and swiftly scrapped by the coalition government in 2010. HIPs required sellers to provide an energy performance certificate, a property information questionnaire and supporting documents before marketing a property. Critics argued they added cost and delay without solving the core problem of gazumping.
The key difference this time is the binding contract element. HIPs provided information but didn't change the legal framework for when a sale becomes binding. The new proposals address both sides of the equation: upfront information and early legal commitment.
What the 2029 timeline means for property investors
The reforms will be introduced "at the end of this Parliament" — meaning 2029 at the earliest. For property investors operating in the current market, this timeline is the most important detail in the entire announcement.
For the next three years, the system remains unchanged. Gazumping is still a risk. Chains can still collapse. The 21.5-week completion time reported by RICS in June remains the norm. Investors should continue to factor fall-through risk into their acquisition strategy and budget accordingly.
But the direction of travel matters. By signalling that binding contracts are coming, the government is shaping market expectations. Sellers may become more realistic about pricing if they know the window for accepting a higher offer mid-transaction is closing. Estate agents may adjust their practices ahead of the new code of practice for property agents — which is due this year, well before the main reforms.
For deal sourcers, the code of practice is arguably more important than the binding contracts. Estate agents will be required to adhere to clearer standards around how offers are communicated, how bids are managed and how chains are disclosed. This could reduce the incidence of phantom bids and other practices that contribute to gazumping.
For deal sourcing strategies, the changes are net positive. Binding contracts reduce the operational risk of sourcing deals that later fall through due to gazumping — a problem that disproportionately affects off-market and auction-to-private-sale transactions where the chain is less transparent.
How the reforms compare to Scotland's system
Scotland already operates a system that the government is now proposing for England and Wales. Under Scottish law, once a buyer's solicitor makes a formal offer and the seller's solicitor accepts it — confirmed through the exchange of "missives" — the deal is legally binding. Either party can be sued for damages if they pull out without a legitimate reason.
Scottish sellers must also provide home surveys to prospective buyers before offers are made, which removes the uncertainty about property condition that often causes renegotiations and fall-throughs in England.
The results are telling. According to industry data, the fall-through rate in Scotland is significantly lower than in England and Wales. Completion times are also shorter — typically 8-12 weeks compared to the 20+ week average south of the border.
The Scottish system costs buyers slightly more upfront — survey costs are paid by the buyer regardless of whether the deal completes — but the overall certainty and efficiency savings more than offset this. The new English system appears to be modelled closely on this approach.
