The energy regulator, Ofgem, said 74,000 Yorkshire Energy (also known as Daisy Energy) domestic customers have been moved to Scottish Power following a “competitive process to get the best deal” for them.

The move comes after small supplier Yorkshire Energy collapsed last week.

All outstanding credit balances will be honoured, including money owed to both current and existing customers of Yorkshire Energy. Ofgem added that Scottish Power will absorb all of the costs of honouring customer credit balances, and during the migration process.

Current and former customers who owe money, or are in debit to Yorkshire Energy should wait to hear from Scottish Power or Yorkshire Energy’s administrators.

Energy supply continues as normal and customers of Yorkshire Energy 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.

For those who remain with Scottish Power, it will be in touch with direct debit customers to explain how to set up their account.

Philippa Pickford, Ofgem’s director of future retail, said: “I am pleased to announce we have appointed Scottish Power for the customers of Yorkshire Energy. Their energy supply will continue as normal and domestic customer credit balances will be honoured.

“Scottish Power will be in contact with customers over the coming days with further information. Once the transfer has been completed, customers can shop around for a better deal if they wish to.”
