Full Plans approval

Before you carry out building works to your home you may need to apply for building regulation approval. A Full Plans application will give you peace of mind because we will check the plans to make sure that your building work complies to the regulations.


Submitting a full plans application will:

  • ensure that the proposed work complies with the regulations;
  • be necessary when borrowing money from a bank or building society to pay for the work;
  • will help builders give you an accurate quote.

A Full Plans application will be thoroughly checked by a building control surveyor and we will let you know if we need any further information. We are required to pass or reject your plans within a certain time limit. We may add conditions to an approval with your written agreement. If we are satisfied that the work shown on the plans complies with the regulations, you will be issued with an approval notice within five weeks, or, where extended by agreement, two months. This will give you the protection of being able to demonstrate that your plans were passed. 

We will also inspect the work during construction for compliance with the regulations.

Full plans procedure is suitable for:

  • any new buildings
  • extensions or alterations to any building other than small single storey domestic extensions
  • extensive internal structural alterations to any building
  • loft conversions

Some buildings are exempt from Building Regulations,  see domestic buildings exempt from building control for more information.
