Energy Shift

We're on track to use our lowest gas and electricity for years. Gas is probably due to better loft insulation, lagging hot water pipes, reflective stuff behind radiators to direct heat back in toward the rooms instead of the windows/walls, turning the TRVs on the radiators down by 1 and closing blinds/curtains when the sun starts going down. For electric I can only think it's changing absolutely every light to LED but the difference is so big I can't be sure. The bills are still going to be massive though.
