The legislation that governs the Building Regulations system in England and Wales and the requirements of Approved Inspectors is made up of both primary and secondary legislation. The Building Act 1984 is the primary enabling legislation under which secondary legislation such as the Building Regulations and the Building (Approved Inspectors etc.) Regulations are made. Approved Inspectors registered with CICAIR Limited are qualified to undertake building control work in accordance with Part II of the Building Act 1984 and the Building (Approved Inspectors etc.) Regulations 2010.
