Third Party Testing

Part P of the Building Regulations was amended in April 2013.

Part of this amendment reads:

An installer who is not a registered competent person may now use a registered Third Party  to certify notifiable electrical installation work as an alternative to using building control body.

In the past the only people able to register an electrical installation were members of the Competent Persons Scheme, or the Local Building Control (LBC).

The LBC generally did not have qualified manpower to carry inspection and testing, and therefore subcontracted the work to an approved company, or refused to carry out the inspections.

This change now means that any qualified electrician can carry out electrical work in Domestic premises and employ the services of registered Third Party test engineer to inspect and test their work, and, subject to it being seen to comply fully with BS 7671 and the latest building regulations, register that installation with the LBC.

TBG have Registered Third Party inspectors and offer this service to our customers.

Third Party Certification

Process for Notifications


The Third Party Certifier (TPC) must be informed in advance of any proposed work that they will be employed to certify before it begins.


The work will need to be Inspected by the TPC at first fix before any work is covered up and at second fix , before undergoing final testing and energisation.


The TPC will complete a Third Party Certifier’s Electrical Installation Report within 21 days and sumbit it for approval by NAPIT.


Once satisfied NAPIT will notify the work as compliant with building control and notify the TPC that Electrical Installation report can be issued to the customer. Within 30 days a Buildings Regulation Compliance certificate will be sent to the customer.
