What are the legal requirements for selling a house in the UK?

The UK legal framework for selling a home is more demanding in 2026 than at any point in the past decade, and the paperwork changed shape this year. Material-information disclosure rules have applied across England and Wales since 2023, anti-money-laundering checks run at both the estate agent and conveyancer level, and on 30 March 2026 the main seller's form was replaced with a shorter version.

The steps below are common to almost every sale. Missing one delays a sale; getting one wrong can unwind it after completion.

What is an EPC and when do I need one?

An Energy Performance Certificate (EPC) rates a property's energy efficiency from A, the most efficient, to G, the least. The certificate must be available before the home is marketed for sale and must be valid, and an EPC lasts 10 years from issue. Sellers without a current one commission it from an accredited domestic energy assessor.

Which legal forms must a UK seller complete?

The Law Society's TransAction protocol forms are the spine of every sale in England and Wales. The seller completes them, the conveyancer checks them, and the buyer's conveyancer works from them. Errors and omissions here are the most common cause of disputes after completion.

The main form changed this year. The TA6 Property Information Form is now on its sixth edition, which cut the form from 25 sections to 15. The fourth and fifth editions were permitted until 30 March 2026, and firms accredited under the Conveyancing Quality Scheme have had to use the sixth edition for instructions taken from that date.

Why did the TA6 form change?

Because the fifth edition had grown. Sections were added to it so that the form would satisfy the material information guidance that applies to property listings, and the result was a long document that sellers found confusing and that asked for listing-stage facts well after the listing had gone live.

After a consultation, the Law Society split the job in two. The sixth edition TA6 is a shorter form for use once an offer is on the table, and a separate material information form exists for sellers who want to answer the listing-stage questions before the home goes on the market. The second form is not compulsory.

What is material information and what must I disclose?

Material information is anything about a property that an average buyer would need to know in order to make an informed decision. The National Trading Standards Estate Agency Team set out three categories: Part A covers tenure, council tax band and price, Part B covers physical characteristics such as property type, rooms, parking and accessibility, and Part C covers anything that might affect a buyer's decision, such as flood risk, restrictive covenants or known building safety issues.

The duty sits on the listing, so it has not moved and it has not softened. What changed in March 2026 is the paperwork you answer it on, not whether you have to answer it.

Failing to disclose material information that the seller knew or ought reasonably to have known is a breach of the Consumer Protection from Unfair Trading Regulations 2008. A buyer can pursue a misrepresentation claim against the seller, the agent, or both, after completion. Honest disclosure is what protects you from that.

Why are anti-money-laundering checks required?

Both the estate agent and the conveyancer are regulated under the Money Laundering Regulations 2017 as amended. Each must verify the seller's identity and address, and in some cases the source of funds, before acting. The checks are routine: photo ID, proof of address, and a short document trail for any large recent deposits. A seller who refuses or delays them cannot complete a sale.

Do I need a conveyancer or solicitor?

Yes. The legal transfer of property in England, Wales and Northern Ireland must be handled by a regulated conveyancer, licensed by the Council for Licensed Conveyancers, or a solicitor regulated by the Solicitors Regulation Authority. The conveyancer drafts the contract, answers the buyer's enquiries, manages exchange and completion, and registers the change of ownership with HM Land Registry.

How early should I instruct one?

Earlier than most sellers do, and the evidence on that has firmed up this year. Research from Rightmove reported on 9 September 2026 found conveyancing was the biggest source of delay for 37% of home movers, ahead of survey or valuation issues at 15% and searches at 11%.

The overall clock has lengthened too. Rightmove reported on 31 July 2026 that the average move in Great Britain takes 216 days from listing to completion, 62 days to find a buyer and 154 days to complete, the longest at that point in the year on its record.

A conveyancer instructed in the week you list has your forms, your identity checks and your title documents ready before an offer arrives. A conveyancer instructed after an offer starts that work with a buyer already waiting.

What about capital gains tax?

If the property is the seller's main residence and has been throughout ownership, no capital gains tax is due, because Private Residence Relief applies. If it is a second home, a buy-to-let, or has not always been the main residence, capital gains tax may apply on the gain above the annual exempt amount. Tax on UK residential property gains is reportable and payable to HMRC within 60 days of completion.

The forms a seller signs in week one shape what happens in week sixteen. Honest, complete answers are worth more than any marketing pitch.

What if I am selling a leasehold property?

Leasehold sellers need a Leasehold Property Enquiries pack, usually called an LPE1, from the freeholder or managing agent. It covers ground rent, service charges, planned major works and any breaches of the lease. The pack takes weeks rather than days to produce, which is why leasehold sales usually run longer than freehold ones. Ordering it the week you list is the single most useful thing a leasehold seller can do.

Is any of this about to change again?

Yes, over the next few years. The government's home buying and selling reform roadmap, published on 19 June 2026, sets out a plan to move key property information to the front of the process in upfront sales packs, so that a buyer has the facts before they offer rather than weeks afterwards.

The roadmap then adds a second step: making binding conditional contracts a requirement once those packs are established, so that an agreed sale is harder to walk away from. In the meantime it encourages the voluntary use of reservation agreements. None of this is law yet, and the timetable runs across this Parliament.

The direction of travel is worth knowing even now, because it is the reason the TA6 was split in two and the reason more sellers are being asked to gather their paperwork before listing rather than after.

How does ValuQ fit alongside the legal process?

ValuQ gives UK homeowners free, side-by-side property valuations from competing local estate agents, without the seller revealing their identity until they choose. The platform sits before the legal stage: agents are compared and chosen anonymously on the evidence, and the legal process begins only once the seller has picked one. Anti-money-laundering checks and the protocol forms follow from that point, with the agent and the conveyancer.

Frequently asked questions

Selling a UK home legally is a process of paperwork and disclosure, not one dramatic decision. The forms are predictable, the rules are public, and the conveyancer carries most of the load once instructed. The seller's job is to answer honestly, instruct early, and keep the calendar moving.
