Bantam It's possible the lightbulbs made the difference. If nothing else has changed. I think lighting is underestimated, it's something you have on for hours a day, they get left on by accident.
Girlie Ledhut.co.uk is good for bulbs, you can get discount codes online for 25-30% off plus you can get cashback off topcashback and quidco. Also the aldi bulbs I bought last year are good. Ikea do them very reasonably too. It's just that not everyone has an Ikea down the road.
Normal energy savers are the Compact Fluroescent lights, they use 8-20 watts. LED ones use 1.5-10 watts.
Buying them cheaply is the key though.
I only keep the useage so low because we lived in a tiny flat years ago on a complicated tariff and would get bills of £900-1200 for a quarter. We both worked full time so we knew we didn't use loads. I would open bills and cry. They would say be very resistant to the idea the meter reading could possibly be wrong but in the end admitted the meter readers equipment couldn't take the numbers for an E10 tariff.
Nothing is left on standby here, I see it as depriving the suppliers of as much money as possible.
Microwaves just packed up. I bet I cant find the flipping receipt for it now.
