Issuing of completion certificate

When we have been notified that the work is completed and we have carried out a satisfactory final inspection, we will issue a completion certificate to show that the work complies with the building regulations.

This is an important document that should be kept and presented if the building is subsequently sold or may be required if you are securing additional funds.

To request a completion certificate email buildingcontrol@wandsworth.gov.uk providing the site address and your reference number.

Private approved inspector

If the work was supervised by a private approved inspector and not by our Building Control Service you will need to contact them for details of any approvals they have given as it is their responsibility to provide you with the completion certificate.
