What happens if my energy supplier goes bust?

It is very rare for an energy supplier to go out of business, but it happened in 2016, with the collapse of GB Energy.

As happened then, any future collapse 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.
