New TA6 Form: What Sellers Need to Know

The TA6 Property Information Form is one of the most important documents you will complete when selling your home. It is a detailed questionnaire about your property that forms part of the legal contract pack sent to the buyer's solicitor during conveyancing.

From 30 March 2026, a new version of this form — the TA6 6th edition — becomes mandatory for all residential sales in England and Wales. If you are planning to sell your property in 2026, you need to understand what has changed and, more importantly, how to fill it in correctly.

This guide is designed to be practical. It covers what documents to gather before you start, walks you through each major section with specific tips, and flags the mistakes that most commonly delay sales or trigger misrepresentation claims.

What has changed in the TA6 6th edition?

The 6th edition introduces several significant changes compared to the previous version. The most notable are:

• Material information questions — New structured prompts aligned with National Trading Standards (NTSELAT) guidance on material information that estate agents must disclose. The form now asks you directly about factors that could influence a buyer's decision.
• Expanded environmental section — More detailed questions on flooding history, flood resilience measures, coastal erosion risk, and energy efficiency improvements.
• Building safety — New questions relevant to multi-occupancy buildings, reflecting requirements introduced by the Building Safety Act 2022.
• Clearer disclosure prompts — Several sections now use tick-box formats instead of open text fields, reducing ambiguity about what needs to be declared.
• Updated planning and alterations section — Explicit questions about permitted development rights, retrospective applications, and whether a certificate of lawfulness was obtained.

These changes are designed to reduce the volume of additional enquiries raised by buyers' solicitors and to bring the form into line with the material information obligations that already apply to estate agents under the Consumer Protection from Unfair Trading Regulations 2008 (CPRs).

Step 1: Gather your documents before you start

The single most effective thing you can do is collect all your supporting documents before you open the form. Sellers who start filling in the TA6 without their paperwork to hand inevitably leave sections incomplete, which triggers rounds of follow-up enquiries and adds weeks to the process.

Here is a checklist of everything you should have ready. Tick off each item before you begin:

Step 2: Complete each section carefully

The TA6 6th edition covers the same core sections as previous versions but with updated and expanded questions. Below are practical tips for each major section, focused on what to write, what evidence to attach, and where sellers most commonly go wrong.

Boundaries (Section 1)

Check your title plan for "T" marks indicating boundary ownership. If T marks are present, state clearly which boundaries you own. If no T marks are shown (which is common on older titles), say "No T marks on title plan" and describe which boundaries you have maintained during your ownership.

Practical tip: Take photographs of each boundary and keep them alongside the form. If a boundary has been moved, replaced, or is in dispute, photograph the current position. This evidence can resolve enquiries that would otherwise take weeks of back-and-forth correspondence.

Disputes and complaints (Section 2)

Disclose all disputes — current, historic, and resolved. This includes noise complaints, boundary disagreements, planning objections you raised against a neighbour, and antisocial behaviour reports. The 6th edition now explicitly asks about resolved disputes as a separate tick-box question, so there is no room for ambiguity.

Practical tip: Write a brief summary of any dispute: what happened, when it started, how it was resolved, and whether there is any remaining risk. Attach copies of any correspondence. A thorough, upfront answer is far less likely to alarm a buyer than a grudging disclosure extracted through follow-up enquiries.

Notices and proposals (Section 3)

List every formal notice you have received from your local authority, a government department, or a neighbour — including planning notices about nearby developments. The 6th edition adds prompts for infrastructure proposals (such as HS2 or new road schemes) that affect your area.

Practical tip: Check your local council's planning portal for any recent applications within 200 metres of your property. If a large development has been approved nearby, it is better to disclose it proactively than to have the buyer discover it through their own searches.

Alterations, planning, and building control (Section 4)

This section generates more follow-up enquiries than any other. List every alteration you (or a previous owner, if known) have made — extensions, loft conversions, new windows, removal of internal walls, rewiring, new bathrooms, and any change of use.

For each piece of work, state:

• What was done and approximately when
• Whether planning permission was required and obtained
• Whether the work fell under permitted development rights (and whether you obtained a certificate of lawfulness)
• Whether a building regulations completion certificate was issued
• The name of the contractor or builder

Practical tip: If you cannot locate a building regulations certificate, contact your local council's building control department — they keep records of all applications and sign-offs. If the work was never signed off, you may need retrospective regularisation (typically £200-£500+) or an indemnity insurance policy. Address this before you list rather than scrambling to resolve it mid-sale.

Guarantees and warranties (Section 5)

List every guarantee you hold — damp-proofing, timber treatment, roofing, double glazing, NHBC (new builds), underpinning, cavity wall insulation, and any insurance-backed guarantees. Note the issuing company, date, duration, and whether the guarantee is transferable.

Practical tip: If you have lost a guarantee, contact the issuing company before you start the form. Many will reissue for a nominal fee. A missing guarantee that should exist (for example, after damp treatment) will trigger an enquiry and may require an indemnity policy if it cannot be replaced.

Environmental matters (Section 7)

The 6th edition expands this section significantly. You will now be asked specifically about:

• Whether the property has ever flooded (including garden, garage, and outbuildings — not just the habitable rooms)
• What flood resilience or resistance measures are in place
• Coastal erosion risk (for properties near coastlines)
• Japanese knotweed — whether it is present, has been treated, or exists within 3 metres of the boundary
• Radon levels and whether mitigation has been installed
• Any contaminated land issues or nearby industrial activity

Practical tip: Do not downplay flooding history. The buyer's solicitor will order an environmental search that reveals flood risk data, and any discrepancy between your answers and the search results will be flagged. If the property has flooded, state exactly what happened, when, the extent of damage, and what remedial action was taken. Attach any insurance claim paperwork or flood survey reports.

Rights and informal arrangements (Section 8)

Disclose all formal rights shown on the title register (easements, rights of way, restrictive covenants) and any informal arrangements with neighbours. This includes verbal agreements about shared driveways, parking, access through gardens, or use of outbuildings.

Practical tip: Informal arrangements are the ones sellers most often forget. If your neighbour has walked across your land to reach their garage for 20 years, that could constitute a prescriptive easement under the Prescription Act 1832. Mention it.

Services and utilities (Sections 12-13)

Confirm every connected service — gas, electricity, water, drainage, broadband, and telephone. State whether each is mains or private. If you have a septic tank or cesspit, note whether it complies with the Environment Agency's General Binding Rules (which require septic tanks discharging to watercourses to be replaced with treatment plants).

Practical tip: If any pipes, cables, or drains cross a neighbour's land (or theirs cross yours), disclose this and note whether a formal easement exists. The buyer's drainage search will reveal the drainage layout, so your answers need to match.

Transaction information (Section 14)

This section asks about restrictions on the sale itself — overage clauses, pre-emption rights, Help to Buy equity loans, or shared ownership arrangements. The 6th edition adds specific questions about whether you have received a completion notice or are subject to any court orders affecting the property.

Practical tip: Check your title register for any restrictions or charges. If there is an overage clause (common on properties built on former agricultural land) or a Help to Buy equity loan, your solicitor will need to deal with this early. Do not wait for the buyer's solicitor to discover it.

Step 3: Cross-check and review

Before you hand the completed form to your solicitor, take the time to review it thoroughly. The most common mistakes on the TA6 are not deliberate lies — they are inconsistencies, omissions, and vague answers that trigger avoidable enquiries.

1. Read the entire form from start to finish. Check that your answers in one section do not contradict answers in another. If you mention an extension in the alterations section, make sure the insurance section reflects any related claims and the guarantees section lists any warranties for that work.
2. Cross-reference against your title register. Your answers about boundaries, rights, restrictions, and charges should match what appears on your official title documents.
3. Check that you have attached all supporting documents. Every planning permission, building regulations certificate, guarantee, and warranty you mention should have a copy attached. Missing attachments will trigger an enquiry.
4. Ask a co-owner or partner to read through it. A second pair of eyes can catch errors, remind you of events you forgot, or spot vague answers that need more detail.
5. Flag anything you are unsure about. Mark uncertain answers and ask your solicitor before finalising. An honest query to your solicitor now is better than a misrepresentation claim after completion.

Why you should complete the TA6 before listing

Traditionally, sellers only start on the TA6 after accepting an offer. This is one of the single biggest causes of conveyancing delays in England and Wales. While you are chasing planning certificates and tracking down warranties, your buyer is waiting — and potentially losing confidence or being tempted by another property.

Completing the TA6 before you list means:

• Your solicitor can send the draft contract pack to the buyer's solicitor on day one after accepting an offer
• You discover any missing documents or compliance issues before they become a problem mid-transaction
• The buyer's solicitor receives thorough, well-prepared answers, which reduces the number of additional enquiries
• You demonstrate to buyers and their solicitors that you are a serious, organised seller — which builds confidence and keeps the chain moving

This is the approach Pine is built around. By helping you complete your TA6, TA10, and supporting paperwork before you go to market, you arrive at the conveyancing stage with everything ready. For more on this approach, see our property information form tips.

Misrepresentation risks: what sellers must understand

The information you provide on the TA6 is legally binding. If a buyer discovers after completion that your answers were false or misleading, they can bring a claim against you for misrepresentation under the Misrepresentation Act 1967. There are three types:

• Fraudulent misrepresentation — You deliberately lied or concealed information. The buyer can claim damages for all losses, and the court can reverse the sale entirely.
• Negligent misrepresentation — You were careless and did not take reasonable steps to check the accuracy of your answers. The buyer can claim damages.
• Innocent misrepresentation — You genuinely believed your answer was correct. The buyer may still be able to rescind the contract, though damages are less likely.

Additionally, the Consumer Protection from Unfair Trading Regulations 2008 (CPRs) make it an offence for traders — including estate agents acting on your behalf — to engage in misleading actions or omissions. The National Trading Standards Estate and Letting Agency Team (NTSELAT) has issued guidance on material information that must be disclosed, and the new TA6 6th edition is explicitly designed to align with these requirements.

The practical takeaway is straightforward: be honest, be thorough, and never guess. If you do not know the answer to a question, write "Not known" with a brief explanation of why. An honest "Not known" is always safer than a confident but incorrect answer. For more on this topic, see our guide to the seller property information questionnaire.

Common mistakes to avoid on the new TA6

Based on common issues flagged by conveyancing solicitors, here are the mistakes that most frequently cause delays or legal problems:

1. Leaving sections blank. An empty answer always triggers a formal enquiry. Use "Not known" with an explanation if you genuinely cannot answer.
2. Omitting building work. Even minor work — replacing windows, adding a bathroom, installing a wood-burning stove — needs to be declared. The 6th edition now includes specific prompts for common alterations, so there is less excuse for overlooking them.
3. Failing to disclose resolved disputes. The form asks about all disputes, not just current ones. A neighbour dispute that ended amicably five years ago still needs to be mentioned.
4. Downplaying flooding history. If any part of the property — including the garden or garage — has ever flooded, you must say so. The buyer's environmental search will reveal flood risk data, and inconsistencies will be questioned.
5. Providing vague answers. "Some work was done to the kitchen" is not acceptable. State what was done, when, by whom, and whether the necessary approvals were obtained.
6. Not attaching supporting documents. Every certificate, permission, guarantee, or warranty you reference should have a copy attached. Mentioning a document without providing it will generate an enquiry.
7. Inconsistencies between sections. If you declare an extension in Section 4, your insurance section should reflect any related claims, and your guarantees section should list any warranties for the structural work.

Timeline: when to do what

If you follow Pine's recommended approach of completing the TA6 before listing, here is a practical timeline:

Getting help with the new TA6

The TA6 6th edition is more detailed than previous versions, but it is also more structured. The tick-box format in many sections means less guesswork about what to write. That said, it can still feel daunting — particularly if you are a first-time seller or have done significant work on the property.

Your solicitor is your first port of call for any questions about how to answer specific sections. However, remember that the factual content must come from you. Your solicitor cannot know whether you have had a dispute with a neighbour or whether the loft conversion was done with proper building control sign-off.

Pine is designed to make this process easier. By guiding you through each section with plain-English explanations and prompting you for the right supporting documents, Pine helps you produce a thorough, solicitor-ready TA6 before your property goes on the market. Combined with upfront property searches, this approach can cut weeks off the overall conveyancing timeline and significantly reduce the risk of your sale collapsing.
