Ever since the height of the energy crisis, when the energy price cap was set at more than £4,000 a year for an average household, I have been on a bit of a quest to reduce my energy bills.
I'd tried simple things to save energy at home, like making the switch from incandescent bulbs to energy-saving alternatives, turning lights off when I leave a room and blocking any draughts that let the cold air in and warm air out. I've also been following the Martin Lewis-approved 4pm rule to keep heat in. But I wanted to do more.
