A further three energy suppliers have ceased trading amid an unprecedented increase in global gas prices.
Igloo, Symbio and Enstroga are the latest firms to go under according to the energy regulator Ofgem.
Around 233,000 customers signed on to the three companies are said to have been impacted.
Energy supplies will continue as the affected customers are being switched to a new provider.
Credit balances will be protected and the energy price cap will remain in force when the switchover is made.
Customers have been urged to wait until a new supplier has been appointed before looking to switch.
The three companies join a number of small energy suppliers to go bust since the start of September.
People’s Energy, Green Supplier Ltd, Utility Point, PfP Energy, MoneyPlus Energy and Avro Energy suffered a similar fate earlier this month.
Ofgem said that it is working with the Government and industry chiefs to ensure that customers will be protected for the winter.
Neil Lawrence, director of retail at Ofgem, said: “Ofgem’s number one priority 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 unsettling.
“I want to reassure customers of Enstroga, Igloo Energy and Symbio Energy that they do not need to worry. Under our safety net we’ll make sure your energy supplies continue. If you have credit on your Enstroga, Igloo Energy or Symbio Energy account, the funds you have paid in are protected and you will not lose the money that is owed to you.
“Ofgem will choose a new supplier for you, and while we are doing this our advice is to wait until we appoint a new supplier and do not switch in the meantime. You can rely on your energy supply as normal. We will update you when we have chosen a new supplier, who will then get in touch about your tariff.
“Any customer worried about paying their energy bill should contact their supplier to access the range of support that is available.”
