Do you need a full plans application?

A full plans application is a type of building control approval for any sort of building work, either domestic, commercial, industrial or large-scale residential schemes.

You’ll need to submit detailed plans if you are doing the following:

  • complex domestic building work, for example, multiple building projects at the same time
  • building work near a public sewer (check if there’s a sewer or drain inside your property boundary)building work on anything other than a house or flat with its own entrance

A full plans application is specifically for building regulations. It’s different to planning permission.

If you’re unsure whether you need a full plans application or a building notice you may wish to read the homeowners guide to expanding your living space.

When you’ll need to apply

You must submit your full plans application before you start any building work. Full plans applications take a minimum of 5 weeks to approve.

We have up to 5 weeks to approve your plans. We’ll extend the approval window to 8 weeks if you need to prepare revisions or provide more information.

Getting a decision on your application

If we're satisfied your application meets our building regulation standards, we'll send you an approval notice.

We may give conditional approval to certain aspects of the works or where information has yet to be included or covered in the specification or design proposals. This will specify any modifications that need to be made to the plans, or we may advise of other plans that must be provided to us.

We will only reject the application if it breaches the building regulations. 

When the work starts

After you've submitted your application and gained approval, you must let us know when the work starts and book site inspections when relevant. We'll come to inspect it at various stages to make sure it meets the building regulations standards.
