Do I need building regulations approval for my conservatory? (Video)
Watch our video on conservatories and the building regulations
Many conservatories, summer houses, sheds and outbuildings can be constructed without building regulation approval. The general rule is that if they are small (less than 30m2), or are built of non-combustible material, or are separated from nearby buildings or land and do not contain sleeping accommodation they are exempt from the requirement to submit an building regulations approval application – although it is best to check with your local building control team before starting work.
Conservatories generally have to be constructed of mainly translucent walls and roofs and have an external type door separating them from the rest of the house.
Foundations and floors can be constructed in a variety of ways, but need to take account of ground conditions, trees and existing drains. It is also good practice to include insulation to make the conservatory easier to heat.
Conservatories constructed of uPVC should have frames that carry British Standard marks (BSEN 126908 and/or BS7412) to make sure they are strong enough to support the weight of the roof. Wooden conservatories will generally require treatment such as staining or oiling to maintain their reliability.
You should check that the timber comes from sustainable sources. Glazing should be toughened or safety glass.
