Energy companies accused of 'green murder' by not passing on £50 levy cut to fixed customers British Gas and SSE will pass on the full cuts to its fixed customers EON and EDF customers on fixed tariffs will not benefit from all of the green levy rollbacks Savvy switchers are being penalised, warns Moneysupermarket Rising bills: Even after the green levy rollback energy bills are set to rise this winter Energy firms have been accused of getting away with "green murder" by refusing to pass on the £50 green levy rollback to all of their customers. Last week This is Money revealed that EON and EDF would not be passing on the full saving to its fixed tariff customers. It means millions of customers who have signed up to longer fixed-term deals will see not see their bills drop by the heralded £50 Just British Gas had confirmed last week that they would be passing on the full saving to its fixed - as well as variable - tariff customers. Today SSE also confirmed that it will pass on the bill cut to fixed customers. However it will not implement the change until March, which means customers will face the higher cost through the coldest winter months. Npower and Scottish Power have yet to announce their position. Moneysupermarket warned that EON and EDF's decision means that those who are savvy switchers and are already on a good value fixed price deal are being penalised. Clare Francis, editor-in-chief at Moneysupermarket, said: 'The reduction of green levy commitments for UK energy providers showed all the signs of being a good thing for struggling households who expected to see it reflected in their energy bills. However, indications are that not everyone will win in the war on the cost of energy and some will essentially lose out because they were savvy and switched to pay less in the first place. We feel this is unfair as these customers are in effect overpaying on the reduced levy whereas others are paying their fair share. Energy companies should evenly reduce the cost of green levies for all customers, and not have a selective approach as to who will get a reprieve. After all, the Big Six blamed the Government levies to justify inflation busting price increases. In his Autumn Statement last week, Chancellor George Osborne promised cash-strapped households that green and social levies would be "rolled back" to help offer some relief from soaring energy bills. It followed repeated pledges from the Prime Minister and Energy Secretary Ed Davey to protect customers by rolling back green levies. The government estimates that the reductions are worth around £50 per household. It is cutting the cost of the ECO, an insulation scheme delivered by major energy suppliers, in a move that should shave £30-£35 off bills, on average, next year. Mr Osborne also announced a rebate on electricity bills, saving the average customer £12 on their bill for the next two years. But the decision by EDF and EON will mean that only customers on variable tariffs will benefit from all of the reductions. Those on fixed deals will get a £12 rebate on electricity bills but not a further £30-35 cut from the reduced cost of the energy company obligation (ECO). A spokesperson for EON insisted that the full savings from the government announcement would be passed on to customers. They added that customers can switch providers at any time because EON does not charge an exit fee. EON said that customers already on fixed deals will, in the majority of cases, still be on products that are lower in price than the altered tariffs, and pledged that the savings would also be reflected in new fixed products. EDF also announced a price hike of 3.9 per cent last month, which it also claimed factored in an anticipated reduction to the green levies. However it also said that the full roll back will not be factored in to fixed tariffs, which are "already competitive." Customers who sign-up to our fixed rate tariffs benefit from knowing that their prices are frozen for the duration of the contract. Prices remain fixed despite that fact that non-energy costs have risen beyond our predictions," a spokesperson said. They added that EDF does not have any early termination fees so customers are free to move if they wish. A spokesperson for the Department of Energy and Climate Change said there was no "practical bar" to savings being passed on to everyone. "We have announced a package that should lead to the households seeing an average saving of around £50 a year," he said.
