Preston-based GB Energy Supply provides gas and electricity to more than 150,000 households across the UK.

In November 2016, following the collapse of the business due to problems caused by increases in wholesale energy prices, GB Energy and its customers became part of Co-operative Energy.

Co-operative Energy has retained the GB Energy brand, and is offering new and existing customers the same level of service and care provided to Co-operative customers

What do I need to do if I want to change my current provider?

The advice from Ofgem is not to switch to another supplier immediately; wait until your new supplier has contacted you. It’s also sensible to take a meter reading, ready for when your new supplier makes contact.

Once you are settled with your new energy supplier, there is no obligation to remain their customer – you still have the freedom to switch.

Changing your energy provider has never been easier. It takes just minutes to run a quote on our site, and within 17 days you could be up and running with your new supplier. You can run an energy price comparison here.

Our video guide below explains how hassle-free the switching process is.

What happens when an energy supplier goes bust?

As happened in with GB Energy in 2016,, any collapse of an energy supplier and its consequences would be managed by Ofgem, the energy market regulator.

Thanks to Ofgem’s safety net, even if your supplier goes out of business, your gas and/or electricity supply will never be cut off or interrupted.

All UK energy suppliers are regulated by Ofgem.

In addition to guaranteeing continuity of supply, Ofgem works to move customers of a failed company to the best possible deal, with any debit/credit transferred to a new supplier that is chosen to inherit the business.
