Building regulation standards
The exacting standards are set by government and cover all aspects of construction, from foundations, structural stability, fire safety (including means of escape in case of fire), to ventilation, energy conservation and the installation of services, such as sanitary accommodation and heating boilers. The standards also ensure the provision of adequate access into, and ease of use of buildings.
There are a number of Approved Documents provided by the Government which give guidance on methods of showing compliance. These may be purchased at Government bookshops or ordered from most major bookstores and may be viewed at the Building Control Office. Alternatively, they can be downloaded from the Planning Portal
