You may be liable for council tax for any building which has been constructed or adapted for use as separate living accommodation
Plans approval is not issued, so we strongly recommend you do not use this procedure unless your builder has the ability to successfully complete the works, you both know exactly what you intend to build and how, and you're confident the work will comply with the building regulations. Work can start subject to you giving 48 hours notice.
Building notices are not acceptable for all types of building work and cannot be used for the following:

What happens next?
Once works have started, one of our building control surveyors will visit and, if necessary, advise the builder on how to ensure compliance.
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, 62 KB) (opens new window) form and emailing it to buildingcontrol@hillingdon.gov.uk.
Once satisfied the work is finished and complies with the requirements of the regulations, a free completion certificate will be issued.
On inspection, if there is any work not covered by the initial charge payment, an invoice will be sent to you referring to the additional items of work.
How to pay
Applications should be accompanied by the correct fee, which you can find in the Building control fees 2025/26 (PDF, 374 KB) document. Use our Online Building Notice application form (opens new window) to submit your application and accompanying payment.
