As the days get darker, colder and longer, households around the country will be switching on lights and turning the heating on and up to stay cosy. However, this also means that households will see their monthly energy bills increase.

The experts at Which? recently shared a simple hack you can use to help save some precious pennies on your energy bills during the autumn and winter months, and keep your home warm. All you need is a towel to do the job. In a recent TikTok video, Which? said: "This towel could go towards saving you £50 a year."

The experts set up a test to find the best type of draught excluder. Draught excluders can help block unwanted drafts of cold air from entering a home through gaps around windows and doors, while also keeping warm air inside.

After its test, Which? found that a simple bathroom towel "does a better job" than a purpose-made draft excluder. Which? explained: "It let less air through our test door than rubber, fabric, and even the classic brush variety.

"Plus a towel fits any gap and requires no DIY. The Energy Saving Trust predicts that draught proofing windows and doors could save up to £50 a year off bills, so it's well worth doing."

According to Ofgem, the average British household has two to three people living in it and uses 2,700 kWh of electricity and 11,500 kWh of gas per year, reported British Gas. This works out at 225 kWh of electricity and 958 kWh of gas per month for dual fuel customers.

However, if your home is electric only, you'd expect your electric usage to be higher. The average monthly cost of electricity and gas can range from £111.94 to £216.87, depending on the size and number of people in the household.

For electricity only, costs can range between £60.51 and £118.44, again depending on size of the property and number of people in the household.
