Shell Energy is to take on 255,000 former customers from Green, one of the latest in a raft of small energy supplier to fail over the past month.
Energy watchdog Ofgem has had to find providers for more than two million energy customers over the past month after soaring natural gas prices drove the collapse of seven small suppliers.
Green, which was registered as Green Supplier Limited, collapsed just days after the firm’s chief exectutive, Peter McGirr, warned that the outlook was “looking bleak”.
Ofgem said on Monday that former and current customers of Green will have any outstanding credit on their balance honoured under the agreement, with no interruption supply predicted during the handover.
The regulator added that Green customers will be contacted over the coming days about the change and are being advised to wait until the transfer is completed before deciding if they wish to change suppliers.
Neil Lawrence, Ofgem’s director of retail, said: “I am pleased to announce we have appointed Shell Energy for the customers of Green Supplier Limited.
“We understand that this news may be unsettling for customers, however, they do not need to worry.
“Their energy supply will continue as normal, and customer credit balances will be honoured.
“Shell Energy will be in contact with customers over the coming days with further information.
“Once the transfer has been completed, customers can switch if they wish to.”
