Smart meters for gas and electricity cost the industry an average of £300 each per household, to supply and instal. This cost is passed on to the consumer with their bills, many of whom think, or are encouraged to think by their energy supplier, that they are compulsory, which is untrue. I don’t have, and refuse to have a smart meter. That now means I am paying towards others smart meters? If so, my energy supplier SP owes me £300 right?
