There are many people having to chose between food and heating, and I can help with both. If you just heat the amount of water you need in the kettle every time you save enough money to heat one room for a day. If you put Radflek or cut a pallet divider and cover with turkey foil behind your radiators you will save 45% of heat loss through the wall behind the radiator, and thus save enough money to heat a second room. If you share homes with a friend over the winter months you will be able to heat four rooms for free.   If you go with a friend to the supermarket and buy all the buy one get one free deals (you can do a few swaps with each other if one of you doesn't like the product) you can get half price food, or donate half of it to your local food bank.
