Ofgem has appointed a new energy supplier after Our Power announced that it had gone out of business.
Our Power, which provided the Isles of Scilly's new energy tariff, confirmed that it had ceased trading earlier this week.
The Isles of Scilly Community Venture organised the Scilly tariff as part of the Smart Islands Programme and said it was "frustrated" by the news, which came as a "complete surprise".
Ofgem has now appointed Utilita, which has around 7000,000 customers, to take on Our Power's 31,000 domestic customers as from today (January 31st).
It said in a statement: "This follows a competitive process run by Ofgem to get the best deal possible for customers.
"Utilita is offering Our Power’s customers a competitive tariff and will honour all outstanding credit balances, including money owed to both existing and former customers of Our Power.
"Warm Home Discount customers who have already been approved by Our Power will continue to receive their payment from Utilita.
"Utilita will absorb the costs of honouring customers’ credit balances and the migration of customers. For existing customers, energy supplies will continue as normal as they switch over to Utilita on Thursday 31 January.
"Customers with prepayment tariffs can continue to top up their meters as they had done previously with Our Power.
"Customers of Our Power will be contacted over the coming days about the changes. If customers wish to switch supplier they should shop around. Customers will not be charged exit fees if they decide to switch to another supplier.
"Utilita has committed to make significant improvements in its complaints handling and answering of phone calls by end of March - making it easier for customers to contact them. This will improve customer service both for Utilita’s existing customers, and incoming Our Power customers.
"Customers with questions should contact Utilita’s customer service team on 03300 583 392.
"More information for Our Power’s customers can be found on the Ofgem website."
