Analysis by charity Citizens Advice shows that around 3.2 million people in Britain borrowed up to £150 to cover the cost of Christmas in 2018. Of this figure, 0.9 million have never switched supplier.

Citizens Advice notes that even with the introduction of the price cap earlier this year, individuals could save more than £150 by switching supplier – and potentially pay off their Christmas bills.

Gillian Guy, chief executive of Citizens Advice, explained: “Switching energy supplier or tariff is often the easiest way to make big savings on your bills. Even with the price cap now in place it’s important to check that you’re getting the best deal.”

Claire Perry, energy and clean growth minister, echoed Guy’s sentiments. She urges consumers to use the price comparison tool that is available on Citizens Advice’s website to see if a better deal is available.

Seven ways to cut your energy bill

• Check you are getting the best deal from your current supplier
• Is there a better way to pay your bills? For example, most suppliers offer a discount for paying bills by direct debit. You may also get discounts for receiving bills online. This cuts down on paper, so is cheaper for the supplier and better for the environment.
• Are you getting all the benefits and help you are entitled to?
• Many people stay on the same tariff or with the same energy supplier for years, without realising they could be getting a better deal elsewhere. By switching tariffs or suppliers, you could save over £150 on your fuel bill.
• The best way to pay lower your bills is to save energy around your home.
• Insulate your home – approximately a third of heat is lost through the walls of your home, and a quarter through the roof.
• There are also lots of small things you can do to waste less energy or lower costs around the home, such as turning off lights and switching appliances off at the wall.
