Arrange for a site inspection
To make sure your building works comply with building regulations, you must provide notice when your work reaches a particular stage so that we can carry out an inspection.
If you contact us before 5pm, we'll try to visit your site the next working day.
If you're submitting an application, we aim to contact you within 2 working days to process your payment and arrange an inspection.
You're legally required under the building regulations to inform us when you'll start your building works. We'll inform you of other stages of your project when we'll need to inspect, up to and including the completed works.
Stages when you need a site inspection
Depending on the project type, typical stages when you may need to inform us are listed below (not all stages will be relevant to some works):
- commencement of works
- damp proof course laid
- oversite ready for concreting (with damp proof membrane laid if appropriate)
- drains laid and visible for checking layout and construction
- drains backfilled and ready for testing for water tightness
- structural timbers
- first fix/insulation
- occupation, normally only relevant when part of a building is finished (eg flat)
- completion of works
Some jobs need extra inspections like reinforcement of concrete structures or fire protection.
We may carry out more than one inspection on a visit and call at other times to check on the work in progress.
We’ll send you an invoice for the inspection fee after the first site visit. This fee covers all further inspections.
To pay building regulation fees (pdf, 96kb) and inspection invoices, call 020 7525 5397 or 020 7525 5582.
The completion inspection must be carried out before your builder has finished and left the site.
You’ll be responsible for the completion of any corrections to the work.
We’ll provide a completion certificate if all relevant site inspections have been carried out and the works comply with building regulations or approved plans.
