GOTO Energy (UK) Limited, which collapsed yesterday, supplies gas and electricity to around 22,000 domestic customers.

It joins Pure Planet (235,000 domestic customers), Colorado Energy (15,000 domestic customers) and Daligas Limited (9,000 domestic customers), who went under last week.

In recent weeks there has been an unprecedented increase in global gas prices which is putting financial pressure on suppliers.

ENSTROGA, Igloo Energy and Symbio Energy, People’s Energy, Utility Point, PfP Energy, MoneyPlus Energy, Hub Energy, Green and Avro Energy have all ceased trading since August.

Ofgem said it is working closely with the 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. If you have credit on your 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 concerned about paying their energy bill should contact their supplier to access the range of support that is available.”

Ofgem has appointed Shell Energy Retail Limited to take on supplying Pure Planet Limited, Daligas Limited and Colorado Energy Limited’s combined total of approximately 252,000 domestic customers and 600 non-domestic customers.

For existing Pure Planet, Daligas and Colorado Energy customers, energy supplies will continue as normal after they were switched over to Shell on 17 October 2021.
