I get asked about Fensa and Certass a lot, and I have come accross a few misperceptions along the way. Firsty, FENSA, is the most widely known name becaue it was the first agency granted the power to register installations in 2002. Certass and Fensa are the 2 main bodies given licence to register your installation with building control should it require it. It is a common miscoception that these bodies are 'arbitrators' in disputes. They will arbitrate to a point, in as much as if they receive a complaint about one of their members, they will investigate, and can of course cancel a membership, purely on the basis that they may not wish to be associated with a company that has a bad reputation
A door that has 50% or less glazing does not require buiding regulations. However as part of membership to certain schemes, the installer may be required as part of his membership to register every installation regardless of building control requirement. In return, the scheme sends you a certificate to tell you that your installation does not need building regs!
A door with side panels will automatically require buiding regulations. This certificate if you get one, is pretty important for when you come to sell your house. You can also bet your bottom dollar, that even if your door did not require regulations, the Solicitor from your buyers will request one, and in the panic and mayhem that ensues during ahouse sale, you will be panicked into purchasing an indemnity insurance for your buyer. Dig your heals in and say 'No! The door is less than 50% glazed.
Please also note, that the regulations came into force in 2002 and anything prior to this did not require regulations and you will therefore not need to provide a certificate. Love Your Door is Certass registered.
