Around one in three property transactions in the UK falls through, costing buyers and sellers roughly £400 million every year in wasted fees and stress. That figure has stuck with me since I first started covering the housing market. It means that if you’re in a chain right now, there’s a real chance you could lose thousands of pounds through no fault of your own — simply because the right information wasn’t available at the right time. I’ve seen this pattern repeat itself over and over: a buyer falls in love with a home, an offer is accepted, and then weeks later a hidden problem like a missing planning permission or an undisclosed leasehold cost derails everything.
The government is now consulting on major reforms to fix this. The Ministry of Housing, Communities and Local Government opened a consultation in October 2025 that runs until December 2025, and a roadmap is expected in the first half of 2026. The proposals include requiring sellers to provide key information upfront, digitising the process, and introducing binding contracts earlier. But until those changes land, you’re still navigating a system where problems like damp or a lack of planning permission for alterations often only emerge after an offer has been accepted. Here’s what you actually need to know.
What Property History Really Means for Your Purchase
When I talk about property history, I don’t just mean who lived there before. I mean the full legal and physical record of the building: what alterations have been made, whether they were approved, what the lease says, and what ongoing costs you’re taking on. The core problem is that this information is scattered across different professionals and paper files, and it rarely reaches the buyer until after they’ve committed emotionally and financially. A thorough house inspection checklist can help you spot some issues early, but it won’t uncover everything buried in the legal paperwork.
Why the Current System Costs You Time and Money
The UK property market contributes around £100 billion annually to the economy and employs 1.2 million people. Yet it takes an average of 120 days to complete a sale once an offer is accepted — a figure that has increased by 60% since 2007. Compare that to Norway, where transactions complete in four weeks or less, with digitisation driving estimated savings of up to £1 billion over ten years. The difference isn’t that UK buyers are slower; it’s that the system forces them to discover problems sequentially rather than upfront.
Consider a typical scenario: you offer £300,000 on a Victorian terrace. The survey reveals damp in the rear extension. Your solicitor then discovers the extension was built without planning permission. The seller’s estate agent didn’t know, and the seller didn’t disclose it. You’re now facing either a costly retrospective application or walking away. If you walk, you’ve lost survey fees, solicitor costs, and possibly your mortgage offer. This happens thousands of times a year. In Scotland, where upfront information and more binding contracts are already standard, fall-through rates are noticeably lower. The government’s own consultation acknowledges that older people are often deterred from downsizing entirely because of this uncertainty, which reduces housing supply and pushes prices up for everyone.
What I’d do in your position: before you even view a property, ask the estate agent for the leasehold information pack, any planning permissions, and the property’s energy performance certificate. If they can’t provide them, that’s a red flag. The hidden costs of buying a home often stem from information that should have been shared at the start.
Where Buyers and Sellers Get Tripped Up
The most common mistakes I see aren’t about choosing the wrong property — they’re about not digging deep enough into the property’s history before committing. Here are the patterns that cause the most damage.
Assuming the Seller Has Disclosed Everything
Many sellers genuinely don’t know what’s wrong with their property. A loft conversion done by a previous owner, a missing building regulation certificate, or an extension built without planning permission — these issues can pass through multiple owners without anyone realising. The government’s consultation notes that problems like damp or a lack of planning permission for alterations often only emerge after an offer has been accepted. Never rely on the seller’s word alone. Your solicitor should conduct full searches, and you should consider a comprehensive property inspection before you exchange contracts.
Ignoring Leasehold Fine Print
Leasehold properties come with ground rent, service charges, and sometimes escalating fees that can make the property unaffordable long-term. The Law Society’s survey of conveyancing solicitors found that 70% believe digitisation will change their role, but many firms still rely on paper-based systems that delay the disclosure of lease terms. If you’re buying a leasehold flat, ask for the last three years of service charge accounts and the ground rent schedule before you make an offer. A property lawyer can review these documents for you — it’s money well spent.
Underestimating the Chain Effect
Around 1 in 3 transactions fail, and chains are a major reason. If one buyer in a chain discovers a problem late, the whole chain collapses. The government’s proposals include giving buyers and sellers the option to enter into a binding contract earlier in the process, which would reduce this risk. Until then, the best defence is to have your own finances and searches completed as early as possible. If you’re selling, consider instructing a conveyancer to prepare the property for sale before a buyer is found — 74% of conveyancers surveyed said they’d be willing to do this.
Overlooking Digital ID and Paperwork Delays
Anti-money laundering checks and other obligations create bottlenecks. The Law Society notes that many firms are less prepared for changes driven by digitalisation than for simple digitisation. This means your solicitor might be waiting weeks for ID verification that could be done in minutes with digital tools. Ask your solicitor upfront what their turnaround time is for AML checks and whether they accept digital ID verification. A good solicitor will have a clear process and communicate it to you from day one.

| Issue | Percentage of Firms Affected | What It Means for You |
|---|---|---|
| Not ready for digital ID | ~33% | Delays in verifying your identity could hold up the transaction |
| Willing to prepare sale before buyer found | 74% | You can ask your solicitor to start work early to speed things up |
| Believe digitisation will change their role | 70% | The profession is evolving — expect more digital tools in the next few years |
What I’d do: if you’re buying, ask your solicitor to run the local authority searches and a water and drainage search as soon as your offer is accepted. Don’t wait for the mortgage offer. Those searches often reveal planning issues or flood risks that could kill the deal, and finding out early saves you money.

The government’s reforms are promising, but they won’t be implemented until at least 2026. In the meantime, you need a practical approach that works within the current system. Here’s what I recommend.
Get a Property Lawyer Involved Before You Offer
Most buyers wait until after their offer is accepted to instruct a solicitor. That’s a mistake. A property lawyer can review the title deeds, lease terms, and any planning history before you commit. They can also flag potential issues with the property’s history that might affect its value or your ability to get a mortgage. The cost is typically a few hundred pounds, but it can save you thousands if it uncovers a problem early. Ask the lawyer to run a preliminary search on the property’s title and any local authority records before you make an offer.
Request a Property Logbook From the Seller
Property logbooks are digital records that store all key documents about a home — from building regulations certificates to service history. The government wants to make these standard, but some sellers already have them. Ask the estate agent whether the seller has a logbook. If they do, request a copy before you view the property. If they don’t, consider creating one yourself after you buy — it will make selling easier in the future. A simple property document organiser can help you keep everything in one place from day one.
Check Planning Permission and Building Regulations
If the property has had any extensions, loft conversions, or significant alterations, you need to see the planning permission documents and building regulations completion certificates. Your solicitor can request these from the local authority, but you can also check the planning portal yourself for free. If the work was done without permission, you may need to apply for retrospective approval — and if that’s refused, you could be forced to undo the work. This is one of the most common reasons transactions fall through, so don’t skip this step.
Understand the Leasehold Costs Before You Commit
Leasehold properties come with ground rent, service charges, and sometimes escalating fees that can double your monthly housing costs. Ask the seller for the last three years of service charge accounts and the ground rent schedule. Check whether the ground rent doubles every few years — some leases have clauses that make the property unsellable after a certain point. A real estate lawyer can explain the terms in plain English and tell you whether the lease is likely to cause problems when you come to sell.
Prepare for the Upcoming Reforms
The government’s roadmap, due in the first half of 2026, will likely require sellers to provide material information upfront. That means if you’re planning to sell in the next few years, you can get ahead by gathering your documents now. Create a digital folder with your planning permissions, building regulations certificates, energy performance certificate, and any guarantees for work done. The Law Society’s survey found that 70% of conveyancers believe digitisation will change their role, so being prepared will make your sale faster and smoother. If you’re buying, the reforms should eventually mean fewer surprises — but until they’re implemented, the current system still requires you to do your own due diligence.
