A draught excluder can be purchased pretty cheaply these days, making them more accessible for budget-tight families. Make sure you fit one in front of your hall and back door and near any other door that is creating a draught.
Avoid filling your fridge or freezer to full capacity as the more food you have in there the harder it has to work. Also, try to avoid opening and closing it too often – when you open the door the warm air goes in and the fridge needs to work a little harder to return to its normal temperature.
Keep the number of times you use your dryer to a minimum. Even if you have a night-time saver mode, it is expensive and uses up lots of energy. Instead, hang your clothes out on the washing line – they will feel a lot fresher by doing this anyway.
Lower the temperature on your thermostat to about 20°C. Your home will still heat up, and you will instantly save yourself money.
