The installation of replacement windows is now included as 'building work' and requires a Building Notice to be submitted, prior to work commencing.

The replacement windows are required to comply with the relevant requirements of the Building Regulations in respect to:

• Thermal insulation;
• Ventilation areas;
• Provision of combustion air for heat producing appliances;
• Safety glazing;
• Means of escape in case of fire.

If the replacement windows are being installed by a firm registered with FENSA or CERTASS as authorised to certify their own installations, or if it is only the glass being replaced, an application is not required.

For full details please contact the Building Control team.
