The two routes to compliance are detailed below: -
1. Part P Self Certification Scheme (Competent Persons Scheme) - if the electrical work is carried out by an electrician who is a member of one of these schemes then a building regulation application will not be required for the electrical work. The electrician will certify that their work complies with the building regulations and issue the owner with a Building Regulations self certification certificate. The Competent Persons scheme will then notify the Local Authority to enable them to retain records of all such work.
2. Building regulation application - if this route is chosen there are two options:-
(a). A qualified, registered electrician carries out or inspects the work. They can issue a design, installation and test certificate under BS7671. Building Control will accept the certificate as evidence that the work complies with Part P. Additional inspections and tests by Building Control may be carried out.
(b). Where the work is carried out by an unregistered electrician or is a DIY installation, Building Control will need to inspect and test the work to ensure it complies with Part P. Alternatively the applicant can have the work inspected and tested by a registered electrician/inspector as in (a) above. They will then be able to issue a Periodic Inspection Report under BS 7671...
