A number of other energy firms could leave the market, warns environmentalists

This year wholesale gas prices have more than quadrupled and many utility firms have been unable to cope with the rising overheads. Now founder of environmental firms warns there could be a domino effect as a major gas supplier to the utility firms runs into problems. In a tweet, Dale Vince warned others to go bust and noted the latest energy firm on Twitter. A number of other companies could just leave the market; He tweeted: And one gas shipper, which sells wholesale gas to 18 utilities customers, is exiting that could cause a domino effect. It comes after Igloo, Symbio and Enstroga ceased trading on 29 September 2010 affecting nearly 233,000 domestic customers. They followed the failures of People's Energy, Green Supplier Limited, Utility Point, PfP Energy, MoneyPlus Energy and Avro Energy affecting almost 1.5 million more households. The cost of wholesale gas has increased by 250 percent in 2021 due to a number of factors, including a cold winter earlier this year which depleted stocks. High demand for liquefied gas across Russia and a decline in supplies from Asia have also contributed. The unprecedented situation has pilled pressure on UK energy suppliers, who are unable to pass on the cost to customers due to the Energy Capacity being laid in place by Ofgem.

Neil Lawrence, director of retail at Ofgem, has reassured all customers affected that they will continue to receive electricity and urged households to wait for a new supplier to be appointed before they consider switching providers. He said: The number one priority for Ofgem is to protect customers. We know this is a worrying time for many people and news of a supplier going out of business can be terrifying.
