Building control


Changes to the Building Control Application Process

  • From October 2023, new regulations came into force. This places new requirements on duty holders, which includes the applicant, client, principal designer and principal contractor. Please read our guidance notes for more information. Applications for Building Control Approval with Full Plans (the new name for Full Plans applications) have changed, and the applicant has a duty to ensure they have competent designers and contractors working for them if they do not deem themselves competent.
  • For Applications for Building Control Approval with Full Plans and Building Notices, the applicant must submit to the Building Control Body a notification of completion in accordance with Regulation 16(4a). Failure to submit this notification will result in the completion certification being withheld. If you would like to find out more about this process, please contact the Building Control Team who will be glad to discuss it further with you.

Harrow Building Control operates a same day site inspection service for the benefit of our customers. If you require a same day inspection you must telephone the office before 9.00am on the day. (020 8736 6058)

At busy times please leave a message and one of the team will get back to you. Unfortunately, we cannot arrange same day inspections by email.

Site inspection times

Site visits are available on weekdays from Monday to Friday. Inspection times are:

  • Morning visits: 10am -12.30pm
  • Afternoon visits: 12pm - 3pm

If booking an inspection by phone and all our officers are busy, you must leave a message on the voicemail stating the following:

  • Property Address
  • Date of the Inspection
  • What is being inspected (foundation, roof etc.)
  • AM or PM       

Our messaging service is monitored continually between 8am-5pm (Mon-Fri) so a member of the team will contact you.

*We will endeavour to carry out same day site inspections when booked by phone only, and before 9.00am that day. You may also contact us on before the date that you require the inspection but we recommend you arrange inspections by phone.

It may be possible to book outside these hours by prior arrangement with a specific officer.
