If an electrical operative who does not hold any gas competencies, but who works for a CORGI Registered business, carries out the work along side a CORGI Registered Gas operative working for the same business, then it is the operative who commissions the gas appliance who has the responsibility to notify.

If an electrical operative is a member of a Part P Scheme, other than the CORGIScheme, and is working alongside a CORGI Registered Installer who is not a member of a Part P Scheme, it is the electrical operative's responsibility to notify their own scheme provider of the work undertaken for compliance with Part P. The CORGI Registered Installer must simply notify CORGI.

The CORGI Part P Scheme is currently only open to CORGI Registered installers, or operatives who work for a CORGI Registered business.
