I have old style gas and electric meters but intend to change soon as the best deals are available to those with smart meters.
There are a number of different catagory of electricity user, namely those with :-
i) Smart meters
ii) Electric vehicles (split into high and low mileage drivers, full BEV and plug in hybrid)
iii) Home batteries
iv) Home batteries with solar
v) Home batteries, solar with Air Source Heat Pumps (although not so many in this catagory lol)
There may be other criteria but all of the above will influence the best tariff for you, so when looking for the best tariff/supplier to use, giving as much of the above info as possible will help in the info we can give.
@Tharg its great to see you back on the Forum.
