So, being part of a CPS allows you to do work in a dwelling consisting of the following and notify local authority:
Work in the zones of a bathroom.
Carry out a CU replacement, installation
install a new circuit.
any other work in a dwelling, you do not need to be part of a CPS. correct?
so my question is: what is required of you to be legally allowed to install and test electrical installations in a commercial, or industrial environment?
