Harrow Building Control is operating a full site inspection service. Other enquiries will be responded to with the available resources, but there may a delay. In advance can we thank you for your patience when emailing or phoning the office.

Book a site inspection

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

  • Morning visits: 10am -12.30pm
  • Afternoon visits: 12pm - 3pm (new revised afternoon time)

To book a site inspection call 0208 736 6058 including same day inspections before 9.00am*.

If 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 for.

If booking the inspection by phone please leave a voice message if you cannot get through. It may be possible to book outside these hours by prior arrangement.
