Energy Costs Gas and Electric Prices and Smart Meters add £350

First Standing Charge:-
I call it 50 pence a day Standing Charge for Electric and 30 Pence a day for Gas that is 80 pence a day for both..

350 day's a year is, by the time you add hidden cost on, is a Pound, £1.00, a day. Then I call it 350 days a year. So this is not far off:-

£350.00 a year in Standing Charge alone!!!

Smart meters cost you £350.00 a year:-
