Building Regulations set standards for design and construction which apply to most new buildings and many alterations to existing buildings.

They are made under powers provided in the Building Act 1984. They ensure the health and safety of people in and near buildings. They also cover: 

  • saving energy
  • access
  • use of buildings

In Wales, we are now responsible for the majority of functions under the Building Act - including making Building Regulations in Wales. The functions that have remained with the UK Government are as set out in The Welsh Ministers (Transfer of Functions) (No. 2) Order 2009 (S.I. 2009/3019).

Current documents and guidance can be seen on our Approved Documents page.

We have proposed our first changes to Building Regulations for Wales in our July 2010 policy statement. These changes are intended to support our aim to achieve zero carbon new build.

A nearly ‘zero carbon’ building is one which uses little or no carbon to heat or cool it (the energy use of the building) and so has low/zero annual net emissions of carbon dioxide (CO2). This definition only covers the Building Regulations and does not cover the non-fixed electrical or gas appliances in the building (like cookers, computers and televisions).

We have reviewed Schedule 1 Part L to the Building Regulations 2010. This covers Conservation of Fuel and Power.

Anyone wanting to carry out building work which is covered by the Building Regulations is required by law to make sure it complies with the regulations. There are two types of Building Control Service available.
