Every single energy supplier in the UK is regulated by Ofgem, the industry regulator. This means that the smaller, lesser-known companies have to follow exactly the same rules as the bigger, more established ones. If a company goes bust, you’ll be covered by Ofgem – they’ll ensure your supply isn’t cut off, and they’ll appoint a new supplier to take over your tariff.
No. When you’ve chosen a new deal, your new supplier will handle the switching process. They’ll contact you to let you know what date you’ll be transferred over, and they’ll contact you around the switching date to ask for a meter reading. They’ll pass this on to your old supplier so they can send you a final bill. You don’t need to contact your old supplier, as the new supplier will handle everything for you.
Twenty-nine states have deregulated electricity, natural gas or both. That allows you to shop for the supply portion of your bill from alternative providers who may offer rates lower than the default supplier – usually a utility. Delivery services and billing will remain the responsibility of the local utility as they own the power lines and wires that keep the lights on.
