Will the Building Regulations apply to the work I want to do?
Questions and Answers
“If I want to build an extension to my home, will the Building Regulations apply?”
YES – but a porch or conservatory built at ground level and under 30m2 in floor area is exempt provided that the glazing and any fixed electrical installation complies with the applicable requirements of the Building Regulations (i.e. Part N ‘Glazing – safety in relation to impact, opening and cleaning. Your Building Control Service can supply further information on safety glazing and electrical safety. You should not construct a conservatory where it will restrict a ladder access to windows serving a room in the roof or a loft conversion, particularly if any of the windows are intended as a way of facilitating escope or rescue if there is a fire.
“If I want to build a garage extension onto my home, will the Building Regulations apply?”
YES – but a carport extension, open on at least two sides and under 30m2 in floor area, is exempt except that any fixed electrical installation must comply with the electrical safety requirements of the Building Regulations. You should ensure that a carport does not interfere with the proper working of a low-level flue outlet from an oil or gas appliance.
“If I want to put up a greenhouse or a small detached building such as a garden shed or summerhouse in my garden, will the Building Regulations apply?”
NO – these buildings will be exempt from the regulations but only providing any fixed electrical installation complies with the electrical safety requirements of the Building Regulations.
“If I want to carry out a loft conversion to my home, will the Building Regulations apply?”
YES – the appropriate requirements of the regulations will be applied so as to ensure, for example: the structural strength of the proposed floor is sufficient; the stability of the structure (including the roof) is not endangered; safe escape from fire safely designed stairs to the new floor; and reasonable sound insulation between the conversion and the rooms below.
“If I want to convert an integral or attached garage to a dwelling into habitable use, will the Building Regulations apply?”
YES – the appropriate requirements of the regulations will be applied so as to ensure that, for example, the existing accommodation is brought up to the standard required for habitable use, including both thermal and sound insulation. Structural alterations to create new window openings and the infilling of the existing garage door opening will need to comply with the appropriate requirements.
“If I want to replace one or more windows in my home, or any other type of building, will the Building Regulations apply?”
YES – if you are replacing the whole of the fixed frame and opening parts. If the work is to your home and you employ a FENSA (Fenestration Self-Assessment Scheme) registered installer you will not need to involve a Building Control Service.
“If I want to convert my house into flats, will the Building Regulations apply?”
YES – the regulations define this as a ‘material change of use’ and specify the requirements with which, as a result of that change of use, the whole or part of the building must comply (e.g. those concerned with escape and other fire precautions, hygiene, sound insulation, energy conservation, and contaminants including radon). The whole or part of the building may therefore need to be up-graded to make it comply with the specified requirements.
