Change to Building Regulations
As of 6th April 2007, it is no longer a building regulations requirement that a self closing device, such as a perco or spring hinges, be fitted to internal fire doors in dwellings. It has become the responsibility of the occupants to ensure that fire doors are closed at night. Closing devices are still required on flat entrance doors and garage doors leading into a dwelling. However, these closers now have to comply with BSEN 1154, which currently means they need to be overhead door closers.
If in any doubt, please discuss the matter with your Building Control Officer before commencing any work.
