Does my work require building regulations approval?
Some building work does not require Building Regulations Approval. The following guide will explain the types of building work exempt from the Building Regulations.
Conservatories and porches
For a conservatory or porch (less than 30m2) to be EXEMPT under Schedule 2 Class VII of the Building Regulations 2000, the glazing must be in comply with Approved Document N. In order to comply, glazing shown within the shaded areas in the diagram should meet one of the following criteria.
- Break safely i.e. be toughened or laminated to BS6206, or
- Be protected i.e. be behind a robust screen which prevents a sphere of 75 mm passing through.
- Resist impact i.e. if ordinary float glass is used it should be of a thickness quoted related to the pane size in the diagram below
Please Note: That the addition of a conservatory may contravene Regulation B1 by affecting the means of escape in case of fire from the building if opening windows are required at the first floor level for escape purposes. Please consult a professional advisor if you are unsure.
House Extensions
The following extensions or building work to your house are exempt from Building Regulations:
A conservatory, porch, covered way; (Note: Any glazing in a conservatory or porch must satisfy the requirements of Part N of Schedule 1) or a car port open on at least two sides. However the area of the extension must not exceed 30m2 and planning permission may be required.
