When to notify us

The type of inspections we carry out

When we acknowledge your application, you will receive an approval notification. This notification will detail the schedule of building regulation inspection notifications - which will outline the stages where we need to make a site inspection.

We will inspect your site at certain points, to make sure that your project is meeting building regulations. Additional inspections may also be required during the work.

Under building control regulations - for any type of application and work - you need to notify us at the following stages (which may or may not need a physical inspection). The minimum notifications we require are:

  • Start of work – notice required two days prior to starting work on site

  • Completion of work - notice of completion of works is required five days prior to the date on which work is considered complete. A completion notice by a person carrying out building work must be completed by all dutyholders and returned to us not more than five days after the work has been completed. Failure to complete and return this may result in a delay in the issue of the certificate of completion
