Any building work that’s ‘structural’ must have Building Regulations consent
So before you carry out work such as constructing an extension, converting a loft or garage, or building a new house, you must first ensure it complies with the Building Regs.
Consent is also required for any structural alterations you want to make, for example work to drainage systems, roof structures, removal of chimney breasts, fitting roof windows, and demolishing or making new openings in walls.
In addition, works such as fitting replacement windows and most electrical work also require consent, although approved contractors can usually ‘self-certify’ compliance.
The Approved Documents
The Building Regulations are grouped into ’approved documents’ (A to Q) according to subject. Architectural designers base their designs around these requirements.
The normal procedure is to produce drawings (typically 1:50 or 1:100 scale) of the proposed works and submit them to your local council Building Control Department, where they will be checked for compliance.
For larger projects you may be asked to obtain structural engineer’s calculations, so Building Control can be sure the loads are adequately supported.
