Even if you do not need planning permission for your extension, because you are using permitted development rights, you must get building regulation approval.
The Building Regulations set out minimum requirements for structural integrity, fire safety, energy efficiency, damp proofing, ventilation and other key aspects that ensure a building is safe.
Most repair work is excluded from the Building Regulations, with the exceptions of replacement windows, underpinning and rewiring. However, apart from certain new buildings such as sheds, outbuildings and some conservatories, all new building work, including alterations, must comply with the Building Regulations.
Typical Examples of Work Needing Approval:
- Home extensions such as for a kitchen, bedroom, lounge, etc.
- Loft conversions. Internal structural alterations, such as the removal of a load-bearing wall.
- Installation of baths, showers, WCs which involve new drainage or waste plumbing.
- Installation of new heating appliances.
- New chimneys or flues.
- Altered openings for new windows.
