Our new gas CH system is up and running and as part of that job I removed all the electric storage heaters. I now need to contant the elec supplier (different from the gas supplier) to change the electric tariff as we no longer need E7. That should be ok (I hope), but I'd also like them to remove the E7 'switchgear' namely, the CU,Mechanical Vener timer, and associated wiring. So just to ask here if there might be any probs asking them to do all that - and do they usually charge for it?
Apart from the above there are a pair of rubber insulated supply cables to a dedicated RCD/MCB for the shower - these cables are pretty old. I'd like to replace the them and the RCD but would need to break the seal to do that to isolate it. Is it ok to do that provided I inform them of the change (I suspect not). I don't want to pinch elect. tia
