Recommended checks before CU change

Former Community Member
Former Community Member
As most of you know I’ve only been qualified for just over a year and I’ve got a quote to do for a cu upgrade.


I know I’m nowhere experienced enough to do EICR’s yet, but what would you guys recommend I check/test before doing the cu upgrade and should I do these checks/tests at the quote stage?

    Fitzy, this is what you have ostensibly, an old Wylex metalcald consumer unit.

    Please pull the main fuse before staring work and get it resealed after you have finished. You do not want to be dismantling a live Henley block, it is very dangerous.


    Also renew the main earth conductor with a length of 16.0mm2 green and yellow. It is easy to do.
