I am not exactly poor but I seem to have become obsessed with saving money.
My top tip for staying warm would be - get an electric underblanket. Heating the air in your bedroom is expensive, but my electric blanket costs 2p per hour on the hottest setting - once you get in you don't really need it on.
2nd top tip. Putting the oven on every day is probably the biggest part of your electric bill. Buy a huge bag of baking potatoes, enough for a month. Nuke them in the microwave then put the whole lot in the oven for an hour. Then put them in the freezer, taking them out as required. A big part of my diet is steamed fish - in a microwave steamer. The defrosted baked potato is heated in the microwave - the vegetables are in the fish steamer. Total cooking time: 3 minutes at 700 watts. I also turn lights off every time I leave a room. I have ditched my desktop pc and only use my laptop. I have an energy meter (supplied by British Gas) - doing all these things my electric cost has dropped to 30p a day.
I wish I could do something about my gas bill. Hmmm....I wonder if I could get an electric blanket with sleeves in it.....
