This year's energy costs have spiralled to almost double the average cost in 2021.

But finance expert Martin Lewis has warned that the burden of costly bills could increase even more the following winter - by 43pc.

In his weekly Money Saving Expert newsletter, he explained that the forecasted higher price cap next April, combined with an end to the government's £400 cost-of-living payments, will mean costs are likely to soar even more.

The energy price guarantee, which restricts the amount energy providers can charge per unit, came into force on October 1 and was due to last for two years.

It will now continue until March 2024.

According to Martin Lewis, the price guarantee is likely to rise by 20pc on April 1, 2023 to £3,000/year for average household bills.

This, combined with an end to the £400 cost-of-living payment, which the government said will end, means costs will increase to 43pc if the cost of fuel does not drop.

However, certain people who meet the criteria will receive help from the government, such as pensioners and people who receive benefits and disability benefits.

Mr Lewis admits the situation may change depending upon developments in the government's policies.

But as the situation currently stands, the Money Saving Expert warns energy costs will rise by 43pc.

What should you be doing to help now?

The finance guru says with no "meaningfully cheaper" tariffs available, you can not switch providers and save.

He advises that people should continue to practice energy-saving tricks, such as making homes draught-proof and adjusting the settings of boilers.

People should also check they are paying the right amount each month through Direct Debit and can use this tool to do so.

Mr Lewis also urges people to check they are receiving all the help they are entitled to.

He said: "This is especially important for people on pre-paid meters who haven't claimed the £400 help."

Additionally, people who are struggling to pay their bills can access a range of services that can help meet the costs.
