Energy prices are due to increase in July, with analysts predicting bills will remain elevated well into the winter months ahead.
The rising cost of gas is being cited as the primary driver behind the expected increase, leaving many households facing sustained financial pressure.
Experts are urging people to take action now, even though many may feel they have already exhausted every possible avenue for saving money.
Approximately 22 million people, representing around 40% of billpayers, currently benefit from the certainty of fixed tariffs on their energy accounts.
Fixed deals lock in the cost per unit for the duration of the tariff, which is typically one year, though the total bill still depends on how much energy is actually used.
Options currently available on the market are cheaper than the price cap level, though a sharp fall in International energy prices could make the savings less clear-cut.
Regulator Ofgem says that receiving a quarterly bill, rather than paying by monthly direct debit, is typically around £140 a year more expensive for households.
There are still approximately seven million so-called standard credit accounts in operation, and while some customers prefer quarterly billing, it remains the costlier option.
Experts say the current warm weather is actually the ideal time to check whether more can be done to block draughts, change cooking habits, bleed radiators and improve overall energy efficiency.
Shorter shower times can also make a difference, with egg timers and even four-minute songs suggested as practical tools to help households manage water and energy usage.
Millions of pounds goes unclaimed in the benefits system each year, with pension credit identified as particularly underclaimed despite acting as a gateway to further financial support for older people.
Grants for energy efficiency improvements may also be available through schemes organised by local councils, with eligibility criteria varying based on factors such as income and location.
Charities such as Citizens Advice can assist people in determining whether they qualify for any available financial assistance or energy efficiency support.
People collectively owe £4.5bn in unpaid bills and charges, yet suppliers say they may write off some debt, provide payment plans, or help with the cost of white goods for those who come forward.
Suppliers have made clear that support is available, but only for customers who proactively inform them that they are experiencing financial difficulty.
