changing a CU and added a new circuit ,which forms do I use

[jonthesparks]

when changing a CU unit do i use an electrical installation cert ? and do I need to test all the circuits ?

Hi Jon, When changing a consumer unit, you are also changing all the protective devices, therefore all the circuits MUST be tested. Yes, you will need to complete an EIC for this.

Your title suggests you are also adding a new circuit - you can use one EIC to cover the CU change and new circuit and the same applies when you are doing the LABC notification.
