And now, energy supplier Octopus Energy has revealed they have (a very cheap) answer.
But what is it? Well, they recommend plugging any openings throughout your property, particularly around door frames, which may allow warm air to leak out while permitting cold air to enter.
The company suggests this simple measure could reduce bills by £80.
According to Octopus Energy’s Cash Energy Saving Tips website, the provider explains: “A continuous draught can quickly undo all the good work of your heating – essentially wasting energy.
You could ask why we are saving around £300pa switching from Octopus to a non renewable supplier, if renewables are so much cheaper?

“If cold draughts are ignored, your heating has to work harder to keep you warm, increasing your energy bills and your carbon footprint.
“Identifying and plugging up draughts around doors, windows, and other gaps can help trap warmth in and make your gas spend go further.
“Professional draught-proofing can cost a few hundred pounds. You can also find draughts yourself using the back of your hand, or with a thermal camera and make your own excluders for free using old fabric scraps. Average saving: £80 per year.”
Common areas to check for draughts include windows and doors, floorboards and skirting boards, chimneys, fireplaces, loft hatches, around pipes and electrical fittings, and vents.

“Getting professional draught proofing for your windows and doors can save you around £85. Professional draught proofing can cost around £250, but DIY draught proofing can be much cheaper.”
