The TA6 property information form: which certificates a seller needs
The TA6 is the form your solicitor asks you to complete when you sell. It does not ask for every certificate in the house, but a handful of its questions are about exactly the documents that go missing. This guide lists them and says what answers each one.
Question numbers below are from the Law Society's TA6 6th edition (2025). If your solicitor uses a different edition the numbers may differ, but the questions are much the same.
The questions that ask for certificates
| Question | What it asks | What answers it |
|---|---|---|
| 5.1(a) | Replacement windows, roof windows, roof lights or glazed doors since 1 April 2002 | FENSA or CERTASS certificate, or a council completion certificate |
| 5.1(b)-(i) | Extension, conservatory, loft or garage conversion, removed internal walls or chimney breast, insulation, other building work | Planning permission, building regulations approval and completion certificate; or a competent person certificate (for example for insulation) |
| 5.2(c) | Copies of those permissions and certificates, marked attached, to follow or not available | The documents themselves |
| 5.2(d) | For work during your ownership, whether you got the approvals and certificates, and if none were needed, why | Your own explanation |
| 5.4 and 5.5 | Breaches of conditions, unfinished work, work without all the necessary consents, or issues still to resolve | An honest answer; this is where a known missing certificate is declared |
| 5.6 | Solar power systems, including the building regulations completion or compliance certificate (for example MCS) | MCS certificate, or a completion certificate |
| 11.2 | Electrical installation work, and its certificates | Council completion certificate, the installer's compliance certificate, or a BS7671 electrical installation certificate |
| 11.3 | Electrical Installation Condition Report (EICR) | A periodic inspection report, if you have one |
| 11.4(d) | Heating installed or altered, and its certificates | Completion certificate or the installer's compliance certificate (Gas Safe for a gas boiler) |
The form tells you to give gas and electrical work at question 11 and not at 5.1.
What counts as a certificate
- Building regulations completion certificate. Issued by the council (or a private approved inspector) after inspecting building work such as an extension or loft conversion.
- Competent person certificate. For some work, such as windows, boilers and electrical work, an installer registered with a competent person scheme can certify their own work instead of getting building regulations approval. FENSA, CERTASS, Gas Safe, NICEIC, NAPIT and ELECSA are the ones people usually mean.
- BS7671 electrical installation certificate. The electrician's certificate that the installation meets the wiring regulations.
The answers you should not guess
The TA6 asks you to answer from your own knowledge, or from the owner's records if you are acting for them. If you do not know, say so: the Law Society's notes say you must. Buyers can rely on what you write, and misleading information can lead to a compensation claim after completion. If an answer is wrong or changes, tell your solicitor immediately.
Give your solicitor any documents that relate to the questions, and tell them about anything lost or missing. They would rather hear it early than find it in an enquiry from the other side.
Questions
Do I need a certificate for every item to complete the TA6?
No. For each item you give the details and mark the certificate as attached, to follow or not available. The form is how you tell the buyer what exists. Not available is allowed, but the buyer's solicitor will then ask what you propose to do about it, which is why people look for a replacement or discuss indemnity insurance.
Do I need a Gas Safe certificate or an EICR to sell?
No. According to the Law Society, neither a landlord's gas safety certificate nor an EICR is a legal requirement for the sale of a property in England and Wales. They matter if the property is sold with a tenant in it, or to a buyer who plans to let it, because a landlord must hold a current gas safety record (at least every 12 months) and an EICR (at least every five years). The certificate for installing the boiler or the electrical work is a different document.
My boiler is old. Do I need an installation certificate?
The Law Society says a gas-fired boiler or solid fuel appliance installed on or after 1 April 2005 will have needed a building control completion certificate or the installer's building regulations compliance certificate. Our boiler certificate guide explains what is held on file.
Where do I get a replacement copy of each certificate?
Because different schemes and council archives hold different types of work (and different eras), the simplest route is to enter your address on My Certs: we search every register and your council in one go, report back within 1 working day, and include up to 2 official copies (no record, no fee). You can also use our certificate checklist to see which items apply to your sale.
Want us to look for you?
Give us the address and we search every register and your council, then order the official copies. £79 including the register fees for up to 2 copies, and no record means no fee.
