How to apply for building control approval

There are three types of applications for building control approval: Building Notice, Full Plans and Regularisation. Find out which type of application you need, and how to apply and pay.

In this section:

Regularisation application

Purpose: If building works have been carried out without building control approval and are unauthorised, a retrospective application can be made to certify that these works are compliant with building regulations.

Regularisation applications can be made for any domestic and non-domestic works commenced on or after 11 November 1985. Any work completed before this date is not covered by the Regularisation procedure. Depending on the circumstances, exposure, removal and/or rectification of works may be necessary to ensure compliance with the building regulations.

How to apply

Your application needs to include:

  1. Plans showing the completed works and how the layout was before the work was undertaken.
  2. The appropriate fee - check the  Current building control fees [483KB]
