They are not forced on anyone. They are a con but the con is that these companies, both water and gas and electric, are telling people that if they get a meter or smart meter fitted they will save money. That is the lying confidence trick that utilities are playing on their customers. BUT, whilst it may come, at the moment water, gas and electric smart meters are not compulsory if you haven't already got one. All new builds have smart meters installed but if you buy a new build you will have far more worries than whether smart meters are fitted or not.
