What your FENSA certificate covers
Your FENSA certificate provides proof that your window and door installations:
- Comply with Building Regulations
- Use energy efficient products
- Are registered with the local council
What’s covered?
FENSA covers the replacement of external windows, doors, roof windows and roof lights in your home, against the relevant Building Regulations. Note that the property must be cited on its original footprint, and the use and size of rooms mustn’t be altered.
What’s not covered?
FENSA doesn’t cover conservatories, porches, new builds, extensions, repairs (frame not included), commercial properties.
Why FENSA certificates matter
Not all installers comply with Building Regulations, and not all of them will register your installation with the local council.
Compliance and registration are required by law.
It’s your responsibility to make sure installations are registered with the local council.
If your installer doesn’t mention that you’re responsible and doesn’t offer a FENSA certificate or other building regulations compliance certificate, you’ll need to pay for an inspection by building control.
If there are problems with your installer and you can’t get them back, you may need to hire another to put things right.
You’ll need to allow a few hundred pounds for this and make sure the installer agrees in their quote to rectify any non-compliance issues found by the building inspector.
Proof the job meets building regulations
A FENSA certificate is a declaration by the installation company to the homeowner that the windows and doors they have replaced:
- Comply with Building regulations
- Use energy efficient products
- Are registered with the local council
A FENSA certificate also:
- Verifies that the warranty is insured
- Is essential when selling the property
