How to apply for building control approval

There are 3 types of applications for building control approval: building notice, full plans and regularisation. If the works proposed relate to a Higher Risk Building (please see the BSR link for definition) you will need to apply to the Building Safety Regulator (BSR) for approval.

Building notice application

Purpose: For simple or small domestic alterations and extensions.

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:


How to apply

Your application needs to include:

  1. a completed application form (this can be completed online by clicking on the orange button below)
  2. a site location plan showing the size, position and drainage of the building (1:1250 scale)
  3. the appropriate fee - check the  Building control fees - 2023/24 (PDF) [287KB].

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) [207KB](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 - 2023/24 (PDF) [287KB] document. Use our Online Building Notice application form (opens new window) to submit your application and accompanying payment.
