Data from Uswitch.com indicates that energy providers in Britain are currently holding around £3 billion belonging to customers, leading to recommendations for families to examine their account positions.

The average household now has almost £200 in surplus on their energy account, a sum that analysts believe deserves attention from consumers nationwide.

Generally, consumers would be anticipated to exit the colder months with little credit remaining, having drawn on these funds during high-demand periods. The advice is to restore these amounts during the milder seasons when usage typically drops.

Despite this pattern, figures reveal approximately 16 million households are presently carrying credit balances as the winter period ends. The aggregate credit retained by suppliers has grown by £179 million relative to the year before, a change analysts link to milder-than-expected winter weather and sluggish modifications to direct debit payments following reductions in energy tariffs.

The price comparison platform advises consumers to keep about two months of their regular payments as a cushion to guard against higher heating costs in the colder months. Those lacking operational smart meters should submit routine meter readings to confirm their account standing and payment schedule match genuine usage and avoid paying more than necessary.

Ben Gallizzi, a energy expert at Uswitch.com, said the majority of British homes are concluding winter with credit on their energy accounts. Although this season typically sees most of this credit used up through greater heating requirements, retaining approximately two months of payments offers protection against future winter expenditure.

With energy prices scheduled to rise in July, households carrying credit beyond two months could benefit from keeping some amount to offset later winter costs. Consumers with particularly large balances should think about asking for a reimbursement and checking their direct debit corresponds to their actual usage. Without a smart meter, providing regular meter readings is crucial for keeping billing accurate.

A 71-year-old homeowner in Lewes, East Sussex named John Routledge built up more than £1,000 in credit by setting his direct debit at a higher level while initially relying on electric heaters before having solar panels and a heat pump fitted. His balance has since fallen to under £700, with intentions to reclaim some of it while preserving the rest as a safeguard against future winter costs.

He said they required electric heaters when they relocated two years ago, which caused them to set their direct debit at a higher figure. Following the heat pump and solar panel installation, their usage has fallen considerably, giving them more certainty about their energy expenditure. He plans to recover some of this credit while maintaining a reserve as protection given the uncertainty of energy pricing, particularly regarding winter bills and possible tariff changes.
