• 1. Here are some tips on keeping your home warm and saving money
  • 2. Loft insulation
    If you haven't got insulation in your roof space, most of the money you spend on heating will disappear through there. Laying insulation is a cost effective way of reducing your heating bills. If your insulation was installed some time ago, it may be worth checking to see if it is the current depth. You may even be able to obtain a grant to bring your insulation up to spec.
  • 3. Keeping warm
    To maximise the efficiency of your radiators in the evening, you can tuck the curtains behind the radiator to ensure all the heat goes into the room and not out through the windows.
  • 4. Turn down your thermostat
    You can save up to £75 a year by reducing the temperature on your thermostat by just one degree.
  • 5. Don't waste hot water
    Being smarter about how you use hot water can save a lot of energy over the year.
    • Washing up in a bowl rather than under a running tap
    • Installing an efficient shower head
    • A shower timer will save a lot of energy over the year by just reducing shower times by one minute
  • 6. Use draught proofing
    Draughts in your home can cause you to set your heating far higher than it should be to counteract the chill. Reducing the draughts can allow you to reduce the thermostat setting and make significant energy savings over the year.Adding draught excluders to external doors, letterboxes and windows can help you keep your home warmer for less and help save energy.
