The challenger supplier, also known as Daisy Energy, has ceased trading after two and a half years. It follows Effortless Energy and Tonik Energy which went bust earlier this year.

Under energy regulator Ofgem’s safety net, Yorkshire Energy customers’ gas and electricity supply will continue uninterrupted. Any outstanding credit balances will also be protected.

Ofgem will now choose a new supplier to take on all of the energy firm’s customers. An announcement is expected to be made on Saturday 5 December and once this supplier has been appointed, it will contact Yorkshire Energy customers.

Yorkshire Energy’s CEO, Annie Faulder, said: “After two and a half years in operation we sadly have begun proceedings to cease trading. We have operated since day one with the simple values of transparency and honesty, paying our renewable obligations on time and having customer service that we are proud of.

“We would like to offer our heartfelt thanks to our customers and colleagues for their loyal support over the years. Continue to expect great service, push for green energy and do your part to get the UK to net zero.”

What should Yorkshire Energy customers do?

Customers should take meter readings today, if possible, ready for when the new supplier gets in contact.

Ofgem said Yorkshire Energy customers shouldn’t switch to another energy supplier until a new one has been appointed.

Once the new supplier has been in contact, customers can ask to be put on their new supplier’s cheapest deal or shop around for a better deal from another supplier. They will not be charged exit fees for switching away from their new supplier.

Philippa Pickford, director of retail at Ofgem, said: “Yorkshire Energy customers do not need to worry, as under our safety net we’ll make sure your energy supplies are secure and domestic customers’ credit balances are protected.

“Ofgem will now choose a new supplier for you and whilst 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 new tariff.”
