Ive got a thermometer in my living room and its absolutely freezing.I simply can't afford to have the heating on all the time.Yesterday I had it on for about 6 hours spaced out from 5am till 11.30pm because my son said he couldn't cope with how freezing it is.My house is over 50 years old.Ive got double glazing,put tape around the door gaps.We are both wearing lots of layers.My loft has insulation.Has anyone got any other suggestions please
