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, with government encouragement, in response to the Building Regulations.

Why is insurance required for customers?

For all replacement window and door installations that are notifiable to FENSA it is a government requirement that companies must have certain insurance policies in place where applicable.

Is FENSA certification needed for Doors?

Doors with less than 50% glazing do not require registration.

Doors in critical locations where the glass comes within 1500mm of the floor level to the start of the glass must contain safety glass (toughened or laminated) and must include the relevant safety mark clearly visible to comply with Approved Document N.
