Do I need to make a building regulations application when installing a controlled fitting in an exempt building?
Guidance from the former Office of the Deputy Prime Minister (ODPM) in 2005 stated that if the building is a ‘small detached building’ , then the regulations don't apply to either its erection or any subsequent work done to it as long as it remains a small detached building.
DCLG further advised the only control is with regard to Parts G (sanitation, hot water and water efficiency) and P (electrical safety).
