Am I being charged twice for my electricty?

OK at that point when modified the CU / fuse box connections - one of the old meters - if you moved absolutely everything over to the other - might have stopped recording use /  become redundant.

Some folk choose to get their second meter removed - if say paying a second standing charge - but for quite a few years - Ofgem stopped suppliers doing that to some complex meter set-ups if billed at single rate - so only paid one.

You probably wouldn't have needed a five port meter in that case - to drive a restricted time feed for the heating. Even if fitted a 5 port meter - their might have been nothing for the meter fitter to connect to the restricted port.

Let us know how you get on.
