All developments covered by the Building Regulations must get a Fire Safety Certificate, according to the Building Control Act of 1990. After a Fire Officer has evaluated the building plans and specifications for compliance with Part B of the Building Regulations, a Fire Safety Certificate is issued. A fire safety certificate certifies your proposed fire safety design, not your finished building's fire safety design. It is a legal obligation to have a Fire Safety Certificate where it is required, it depends on how old the building is, what the building is being used for and what type of work is going on in the building.
