My tips for keeping your home warm in winter while keeping your lower bills as low as possible:
Easily check your doors and windows for draughts on those windy days by holding a piece of tissue paper up against their internal frame. If the paper moves in the breeze, you should seal it up. Use a rubber seal to fill the gap, and there is a wide range of options available.
Door snakes aren't just for front doors. Use them to isolate rooms to keep heat trapped within the areas you're using.
Heavy linen or woollen curtains that fall below the window sill are a fantastic way to stop heat loss through windows. Adding pelmets can also assist. - MitchellMc
Insulation is so important. Makes a huge difference. A much more simple tip is just keeping a rug or two or a doona on the couch for watching TV. I get cold when I'm not moving around the house, but being able to huddle under a rug stops the temptation of turning up the heating too high. - Isobel
Don't forget the simple draught stopper or door snake. They really can make a difference to the temperature of a room. - CathD
