Building permission

Replacing existing windows and doors

You will not require building permission to replace windows, doors or roof lights in a dwelling provided the work is undertaken by a FENSA Registered Company.

What is FENSA?

FENSA stands for the Fenestration Self-Assessment scheme. It has been set up by the Glass and Glazing Federation (GGF) and other industry bodies.

FENSA certificates act as documentary evidence that the installation work has been self certified as complying with the building bye-laws. A registered installer will be approved to carry out the work to comply with building bye-laws without you having to apply for building permission.

What if I don't want to use a registered installer?

If you choose not to use a registered installer you will need to make a building application, using form B3

Commercial and new buildings

FENSA does not apply to commercial premises or new build properties. In both of these instances you are required to go through the building control process. FENSA registration is also not applicable to the installation of conservatories or porches by a FENSA registered business.
