Coronavirus (COVID-19) update: Building Control is open for business as usual

Due to the council prioritising its capacity to deal with the ongoing Coronavirus (COVID-19), our Building Control services are still operating, and will continue to deal with applications and site visits, but some phone lines are now closed (please use 0208 736 6058). Please be aware there may be a delay due to our current limited resources. 

Online applications

Our Harrow building control team is accepting online applications via the Submit-a-plan web portal.

The Submit-a-plan web portal submits applications online to local authorities across the country free of charge.

There are lots of benefits of submitting your plans including:

  • Free of charge to use.
  • Open 24 hours a day 7 days a week.
  • No printing or postage required.
  • Applications can be managed and tracked online.

Site inspections

Harrow Building Control is operating a full site inspection service. Contractors should be aware and be following guidelines in respect of working on site.

When arranging a site inspection please consider the following:

  • If anyone at the site (owner or contractors) has been ill and displaying coronavirus symptoms;
  • Could the inspection be carried out in the absence of the occupants/contractors if necessary;
  • Will there be vulnerable people on the premises.

If the answer is yes to the first question then the inspection should seek to be delayed. If the answer is yes to the last question then a discussion should be had on how best to proceed safely.

Other enquiries will be dealt with the available resources but there may a delay in responding.

In advance can we thank you for your patience when emailing and/or phoning the office.

Book a site inspection

Site visits are available on week days 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 0800-1700 (Mon-Fri) so a member of the team will contact you.

Please note that in the climate with Coronavirus, we may take a consultation to examine whether it is safe for us to visit (see above).

*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 bcontrol@harrow.gov.uk 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 of these hours by prior arrangement.
