When you need Building Regulations approval from Building Control

You must check if you need approval before you construct or change buildings.

What building regulations are

The building regulations are minimum standards for the design and construction of, or alterations to, virtually every building. They contain a list of requirements providing standards for construction and energy efficiency whilst taking into account the health and safety and needs of building occupants.

They cover all aspects of the build process, including foundations, damp proofing, stability, insulation, ventilation, heating, sanitation, fire protection and means of escape. They also make sure there are adequate facilities in certain types of buildings for people with disabilities.

Types of work covered by building regulations

You may need approval for a variety of projects including:

  • the erection or extension of a building or dwelling
  • installation of a new bathroom, shower or WC involving new waste pipes or underground drainage
  • the conversion of a building that creates one or more extra dwelling units
  • the conversion of more than one unit into fewer units
  • the building of an attached garage
  • the conversion of a loft or other roof space to habitable accommodation
  • removal of load bearing walls or walls which might affect the means of escape
  • garage conversion to habitable room
  • underpinning foundations
  • forming new openings in external walls for extra windows or doors
  • installing replacement windows or substantially glazed doors (more than 50%)
