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
