Make a building regulations application: step by step

Check what building regulations application you need, book a site inspection and get a completion certificate.

1
Before you start your construction project, you should:
- check if you need building regulation approval
- check if you need planning permission
If you have started construction without getting consent or moved into a property that does not have a certificate, you can get building work certified.
2
If an application is required, the next step is to decide if you should make an application for approval with full plans or submit a building notice.
Apply for an application for approval with full plans - used for new buildings and extensive building work
Submit a building notice application - used for domestic work and smaller-scale projects
For higher risk buildings:
If your project is for a higher-risk building which has at least 7 storeys or is at least 18 metres in height and either:
- is a hospital or care home
- has at least 2 residential units
You will need to apply for approval for higher risk buildings on the Gov.uk website.

You will need to notify the Building Control Team on 2 occasions before booking a site inspection:
- at least 2 working days before you intend to start work
- in writing, within 5 working days of the works 'commencing'
Work has 'commenced' when:
- for new build properties, you've built the ground floor level including all foundations and any basement or extensions
- for any other building work, 15% of the planned work has been completed
Notify the Building Control Team when work has started or commenced.
