ive just had my boiler replaced by British Gas and I’ve got a few electrical questions they didn’t cover. Their electrician pointed out that I need a 10mm earth cable from my consumer unit to the gas pipe and water main. That’s fine and I can get that done.
Previously the switch for the immerser heater and the switch for the heating controls both had earth cables coming out and running down to a clamp on the heating pipes, which then looped around to a few more pipes. These cables have been cut and not renewed, and the electrician made no mention of them. Is this supplementary bonding still required? And should it also be connnected up to the new 10mm earth? I have a consumer unit with RCDs that both switches connect back to.
