The energy regulator, Ofgem, said 18,000 Breeze Energy customers have been moved to ‘Big Six’ provider British Gas following a “competitive process to get the best deal” for them. The move comes after Breeze Energy collapsed on Wednesday.

All outstanding credit balances will be honoured, including money owed to both current and existing customers of Breeze Energy. Ofgem added that British Gas will absorb a significant portion of costs.

Current and former customers who owe money, or are in debit to Breeze Energy should wait to hear from British Gas or Breeze Energy’s administrators.

The provider will be in touch with Breeze customers over the coming days to set up their account. If customers wish to switch supplier they will need to compare tariffs in the market. Customers won’t be charged exit fees if they decide to switch to another supplier.

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

“British Gas 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.”
