What happens next?

Plan checking

Once your completed application has been received, your plans will be checked for compliance with the building regulations. You will normally receive a formal decision within 5 weeks confirming whether the application is approved, approved subject to 'requirements', or rejected. Please note: if you engage an independent agent to submit your application on your behalf, all correspondence will normally be conducted through the agent.

Work can start at any time after submitting the application, subject to giving 48 hours' notice.

Please note: However, you are strongly advised to await a formal approval, so that you are fully aware of all requirements before work begins.

Inspections

The team will inspect works throughout the project at appropriate stages and advise the builder where necessary on how to ensure compliance with the Building Regulations.

Completion

Within 5 days of completing the works, you are required to submit a Notice of Completion, by completing the  LABC Regulation 16(4A) Completion Notice (PDF) [207KB] form and emailing it to buildingcontrol@hillingdon.gov.uk.

Once satisfied that the work is finished and complies with the requirements of the regulations, a free completion certificate will be issued.
