Do I need building regulations approval for an extension?

Planning to have an extension on your home can be very exciting, but you may have a lot of questions, including whether you need building regulation approval. The extension will have a major effect on your home and on your neighbours. Even if you don’t need planning permission, you still may need building regulation approval.

Most extensions of properties require approval under the Building Regulations, however, there are a number of classes of new buildings or extensions of existing buildings that do not need Building Regulations approval. You can find out if you are exempt from the regulations here.

When you draw up your plans, you need to consider how the extension will affect your home, garden and natural light in existing rooms. Another thing which is important to consider is the building materials you will use. If you decide that your home is suitable for these changes, then you will need to get plans drawn up and get them approved by your local council's building control team.

Ensure you are including the following in your plans/details:

  • Foundations
  • Floors and walls
  • Roofs
  • Drainage
  • Fire safety
  • Stairs, handrails, and banisters
  • Sound-proofing
  • Fire escape
