From 1 December 2026, we will only accept electronic submissions using Submit-a-Plan. It is free to use and allows you to submit, track and manage your Building Control application. Creating a login is quick and only needs to be done once. After that, you’ll have ongoing access to your applications, inspections and documents.
Check if you need building control approval
Planning permission vs building regulations
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
energy efficient
Planning permission relates to the:
use of land
appearance of buildings
impact on the environment
You can find out about our planning service, or view more information about planning on the Planning Portal.
When you need approval
You need building control approval if you are:
building a new structure
extending an existing building
carrying out alterations
Building regulations apply to most types of building work.
To help you understand if you need approval, you can use the interactive guide on the Planning Portal, which explains when you need building regulations approval.
However, you cannot submit a Building Control application via the Planning Portal.
Work completed without approval
If work has already been carried out without building control approval, you can apply for retrospective approval (regularisation).
