Entice Energy supplies around 5,400 domestic customers and Orbit Energy supplies around 65,000 domestic customers.

Ofgem said an unprecedented increase in global gas prices is putting financial pressure on suppliers and that it is working closely with government and industry to make sure customers continue to be protected this 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 affected customers that they do not need to worry: under our safety net we’ll make sure your energy supplies continue. 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 concerned about paying their energy bill should contact their supplier to access the range of support that is available.”
