I have an E7 supply for storage heating in my Norfolk cottage as there is no gas in the village. I had a key meter which was a pain in the backside. I asked the supplier to replace this with a smart meter and was told that I could not have one as the phone signal was not good enough in my village.


The key meter supplied 2 consumer units one for the domestic and one for the E7. The E7 was supplied by a contactor switched by a pair of insulated and sheathed small CSA singles and a sealed fuse carrier.


After a lot of effort on my part to prove I was creditworthy the day came for the man to turn up to replace the meter. On arrival I said I wanted a Smart meter and was told on the phone I could not have one due to the poor phone signal. Nonsense says the man I have just fitted one in this road. Out he goes to the man and comes back with a box of tools and a Smart meter. Opening the meter cupboard he says no you have an E7 supply and we don't do 5 hole Smart meters. Back to the van and comes back with a dumb 5 hole meter. He stripped out the old contactor, fuse carrier and conductors so now the line conductor from hole 5 supplies the E7 consumer unit direct.


I have been changing the perfectly good E7 heaters to newer ones that meet the visual requirements of the senior management. I have one left to change and have been told that you cannot buy ordinary E7 heaters anymore without additional digital controls which I do not want, is that true?
