To make sure your building works comply with building regulations, you must give us notice when your work reaches a particular stage, we'll then carry out an inspection.

You're legally required under the building regulations to tell us when you'll start your building works.  We'll tell you of other stages of your project that you're required to let us know to inspect, up to and including the completed works.

The building regulations have recently been updated. For applications deposited from the 1 October 2023, the person responsible for the works (the client), must submit a  pdf Declaration of Completion (168 KB) when the work is completed.

You need to send this to us within 5 days of the work being completed so we can issue a completion certificate.

This regulatory requirement is in addition to the normal inspection process. You're still required to give us notice and book a site inspection for staged inspections and completion.

Stages when you need a site inspection

Depending on the project type, typical stages when we may say that you need to tell us, are listed below. Not all stages will be relevant to some works.  

  1. When you start work (commencement).
  2. Excavation for foundations.
  3. Damp proof course laid.
  4. Oversite ready for concreting (with damp proof membrane laid if appropriate).
  5. Drains laid and visible for checking layout and construction.
  6. Drains backfilled and ready for testing for water tightness.
  7. Structural timbers.
  8. First fix/insulation.
  9. Occupation, normally only relevant when part of a building is finished, for example a flat.
  10. Completion of the whole job.

Some jobs need extra inspections like reinforcement of concrete structures, or fire protection.

We may carry out more than one inspection on a visit and call at other times to check on the work in progress.

Inspection fees

We'll send you an invoice for the inspection fee after the first site visit.  This fee covers all further inspections.

Find out how to pay building regulation fees and inspection invoices.

Completion inspection

The completion inspection must be carried out before your builder has finished and left the site.

You'll be responsible for the completion of any corrections to the work.

We'll give you a completion certificate if all relevant site inspections have been carried out and the works comply with building regulations or approved plans.
