  • It’s a listed building
  • It’s in a designated area, e.g. a conservation area or an Area of Outstanding Natural Beauty (AONB)
  • The area is covered by an additional Article 4 direction
  • The replacement doesn’t have a similar appearance to the existing building
  • If you’re changing the existing width of the door space

What is FENSA certificate?

FENSA is a government-authorised scheme that acts as proof your installation was completed in compliance with building regulations and your local council was notified of the installation. DesignHaus is an official FENSA Approved installer, meaning you won’t need your installation inspected by a Local Building Control Officer.
