Who do I contact if my energy supplier goes bust?

If your energy supplier goes bust, you won’t need to contact anyone. Ofgem, the UK’s energy regulator, has protective measures in place for customers of suppliers gone bust. They’ll arrange for your tariff to be transferred to a new supplier, with no disruption to your energy.

However, once the transfer is complete, you’ll usually be placed on your new supplier’s standard variable tariff, which is usually its most expensive. This means you’ll probably want to contact them to move onto their cheapest tariff. Unfortunately, during the current energy pricing crisis, there are no truly ‘good’ deals currently available.
