Do you have a refrigerator and/or freezer on? I think they take at least two units each day. So that could be 50p these days.
I found some time go that I was not usng my fridge-freezer, so I switched it off. So maybe saving around at least £180 a year now.
Of course, many people need a fridge-freezer facility. It just happens that I don't these days.
They might not be using as much as you think, StarDreamer
I have both a medium-sized fridge-freezer and a medium-sized chest freezer.
Last September, when we were going away for 12 days, I decided to see how much they used while we were away, as they would be the only things left running.
.
Only 19 units had been used when we got back, so if my maths is right, that only worked out at about 1.6 units a day for two appliances.
That was less than I had expected - though still enough to make it worth turning off unused appliances!
