UK households send a "wake up call" to energy companies in new campaign.

Over 12,000 bill payers are set to take action to claim back energy credit in protest at Britain's broken energy system. [1]

The public is now being urged to join with these Warm This Winter and 38 Degrees supporters to reclaim unused customer credit. Currently UK energy suppliers are sitting on over £3bn worth of customer credit, with nearly a third of UK households (32%) in the black to their energy supplier all year. [2]

The Warm This Winter campaign has called on people to join in the Big Energy Credit Claim Back which starts on Wednesday, May 22, as early summer is the ideal time to reset energy bill direct debit payments for the year ahead. The campaign will make clear that customers should not cancel their direct debits though as this could lead to higher unit costs being imposed on households.

Research by the campaign suggests that 38% of those in permanent credit live in households with low incomes and may have cut back on energy use or other essentials because the direct debits set by energy firms are far too high.

Experts, including Martin Lewis, have recently pointed out that while it is sensible to build up credit in the summer months to pay for higher energy use in the winter, customer credit balances have become too high.

Figures suggest that the combined bank interest likely to have been earned by customer credit balances was at least £159m in 2023 alone. [3]

Warm This Winter spokesperson Fiona Waters said: 

“Energy companies are sitting on over £3 billion of bill payers’ money whilst providing an appalling service in many cases and making billions in profits.

“The Big Energy Claim Back is a way people who pay by direct debit can issue a wake up call to companies that customers are not prepared to be ripped off anymore and demand energy suppliers provide a fit for purpose service. Whether it’s smart meters that actually work, customer service centres that pick up the phone to fair tariffs, an end to extortionate exit fees and just basically doing their job.”

The protest is backed by charities including the National Pensioners Convention to leading campaign groups, such as 38 Degrees and the End Fuel Poverty Coalition.

Simon Francis coordinator of the End Fuel Poverty Coalition said: 

“It’s highly concerning that low income households may have been charged too much on their direct debits leaving them to struggle to make ends meet during the cost of living crisis.

“With the huge sums being earned in interest by the energy firms, the least they can do is make sure that credit balances are not running too high, direct debits are set appropriately and the interest they have earned is either paid back to consumers or used to cancel energy debt of those most in need.

“Of course, customers should use caution when claiming back as their direct debits may be increased by their energy firm - but making sure a supplier has a regular meter reading is the best way to ensure accurate bills.”

Matthew McGregor, CEO at 38 Degrees, said: 

“Claiming back the cash we’ve been overcharged is a simple way for busy people to show energy companies they are sick of this broken energy system. That's why thousands upon thousands of us are coming together to move millions of pounds straight from those companies back into the pockets of hardworking people. 

“By claiming back their credit, people can claw back some much-needed cash whilst sending a clear message to energy companies. But this crisis needs proper government action too and this should be a wake up call to all political parties: from cheaper rates for those struggling the most to a proper plan to tackle energy debt, customers need help and they shouldn’t be left to take on the energy industry by themselves.”

Jonathan Bean from Fuel Poverty Action said:

"Yet again energy firms have been caught overcharging us. We demand our money back and proper action from Ofgem.”

Jan Shortt, General Secretary of the National Pensioners Convention, added:

“People have been struggling to pay their bills and it is shocking to learn that these bills may have been set far too high.  Some energy suppliers will act and give credit back, most don't so consumers need to know how to get their credit back.” 

Warm This Winter has launched a guide which includes advice and guidance on how consumers can claim back their credit. The guide also includes areas consumers should watch out for, for example, it is important that people do not cancel their direct debits or else they may be moved onto a higher tariff.
