Check if you need building control approval
You need building control approval if you are building, extending or altering a building, as building regulations apply to most building work.
You can view an interactive guide on the Planning Portal, which explains when you need building regulations approval.
If work has already been carried out without building control approval, you can apply for retrospective approval (regularisation).
Even if you don’t need building control approval, you may still need planning permission.
The building regulations make sure that buildings are safe, accessible and energy efficient. Planning permission deals with the use of land, the appearance of buildings and the impact on the environment.
