Planning and building control

Tell us when building work has finished

Once your building work has finished, you must tell us within 5 days so we can arrange a final inspection and issue a completion certificate.

This is normally done by the person who submitted the original building notice or full plans application (Regulation 12) - usually the principal contractor carrying out the building work.

You will need to provide a signed statement from the client, each principal or sole designer, and each principal or sole contractor, stating the date they were appointed and that they have fulfilled their duties under Part 2A (dutyholders and competence) of the Regulations.

If more than one dutyholder appointment is made, details and confirmation is required for each contractor/designer appointed by the client.

Before you start

Download the completion of works declaration template and ask all parties to sign the confirmation.

Take a photo or scanned image of the completed form. You will be prompted to upload this when you submit the completion of works form online. You should have to hand:

  • Building regulations application number
  • Site address
  • Client contact details (name, address, phone, email)
  • Principal designer/sole designer contact details (name, address, phone, email)
  • Principal contractor/sole contractor contact details (name, address, phone email).

This is a requirement under Regulation 16 paragraph (4A).

How to inform us

Complete the notice of completion form below and attach the signed declaration template. There is no fee associated with giving notice of completion.

What happens next?

Once we have received all the relevant declarations, we can issue a completion certificate.

You will need a completion certificate if you sell your property to show that works carried out have been approved.

If the works carried out involve regulation 7A of the Energy Performance of Building Regulations or regulation 38 (fire safety) of the Building Regulations, the contractor or person carrying out the work must also tell us that they have passed on the certificates and documentation to the owner.

If we don't receive these declarations, we cannot issue the final completion certificate. Find out more about energy performance and fire safety and notify us online.
