FENSA Certificates: Why They Matter When Selling Your Home
If you've had windows or doors replaced in your home in {location}, you should have a FENSA certificate for the work. Many homeowners don't think about this document until they come to sell — and by then, a missing certificate can cause real problems. Here's everything you need to know.
What Is FENSA?
FENSA stands for the Fenestration Self-Assessment Scheme. It's a government-authorised scheme that allows registered window installers to self-certify that their work complies with Building Regulations. When a FENSA-registered installer fits your windows, they notify your local authority on your behalf and you receive a certificate confirming compliance.
Why the Certificate Matters
Replacing windows is controlled building work under the Building Regulations for England and Wales. This means every installation must either be signed off by the local authority building control team or certified through a competent person scheme like FENSA.
When you sell your property in {location}, your conveyancer will check for FENSA certificates or building control sign-off for any replacement windows. If you can't produce either, the buyer's solicitor will flag it as a problem. This can lead to:
- Delays in the sale while you apply for retrospective approval
- The cost of a regularisation certificate from the local authority (typically £200-£500)
- Buyers requesting a price reduction to cover the risk
- In the worst case, buyers pulling out of the purchase
What If You Don't Have a Certificate?
If your windows were installed by a non-FENSA installer and no building control sign-off was obtained, you have two options:
- Regularisation certificate: Apply to your local authority for retrospective approval. An inspector will visit to check the installation meets standards. This costs money and there's no guarantee of approval if the work is substandard.
- Indemnity insurance: Your solicitor can arrange an indemnity policy that covers the buyer against future enforcement action. This is cheaper and quicker, but it's a workaround rather than a proper solution.
How to Check Your FENSA Certificate
You can verify a FENSA certificate online at the FENSA website using your postcode. Certificates are registered against the property address, so even if you've lost the paperwork, the record should exist if a registered installer did the work.
What to Do Now
If you're planning to replace windows in {location}, always use a FENSA-registered installer. Ask to see their registration card and check their details on the FENSA website before signing a contract. The certificate is included as part of the service — there's no extra charge.
If you're selling a home and can't find your certificates, check the FENSA online database first. If nothing comes up, contact your local authority building control department to see whether any record exists. Sorting this out before you list the property will save time and stress during the sale.
