The Building Regulations process explained
Although it may seem daunting, the process of making an application is quite simple and can be broken down into the following five stages:
1. Check to see if the work you intend to carry out requires a Building Regulations application
Examples of where an application is required are: extensions, loft conversions and structural alterations.
For further information please see:
- Common building projects (on our website)
- Do you need permission? - on the Planning Portal website

2. Make a Building Regulations Application
If an application is required the next step is to decide if you are going to make a Full Plans application or submit a Building Notice, for more information see:
Complete the appropriate form and submit it to the Authority with any additional information (ie plans, structural calculations) and the appropriate fee.
3. Inform the Authority 48 hours prior to commencing work on site
To do this you will need to contact Building Control.
4. Arrange site visits to allow a Building Control Surveyor to inspect the work as it progresses
The number and type of inspections required depend on the type of work. Minor works generally need fewer inspections than complicated projects. However, you or your builder must tell us 24 hours before the following stages of the work (although 24 hours notice is required in the Building Regulations we will visit the site if contacted before 10am on the day):
- commencement of work
- excavation of foundations before concreting
- foundations when constructed
- damp Proof Course when laid
- site concrete or floor slab (before being laid)
- drains (before backfilling)
- drains (after backfilling)
- prior to occupation
- completion of work
5. The final stage
After the completion inspection and as long as all work meets the requirements of the Building Regulations, either a completion certificate or a confirmation notice (dependent on type of application) will be issued and should be kept for any future property sale.
