Replacement windows and doors application

Replacement windows and doors on domestic properties need to meet building regulations.

If the replacement windows and doors are installed by anyone other than a FENSA, CERTASS or BSI registered installer, then you will have to complete a replacement windows and doors application form and forward the appropriate fee.

Download a copy of the  Replacement windows and doors application form (PDF 53.1 KB), then print it out, complete and return to us.

When replacing windows or doors, it must be ensured that:

  • the opening parts of windows are not reduced in size so that escape out of the windows is made more difficult
  • the ventilation provided to the room is not reduced
  • the replacement is thermally efficient. Single glazing is not acceptable except in the case of listed and historic buildings or buildings located within conservation areas.

A FENSA, CERTASS or BSI registered installer self-certifies and therefore no application has to be made to Building Control. Each registering body notifies us of work carried out by one of its installers.

For further information on any of the above, contact our administration team.
