Is your energy deal coming to an end?

If your fixed energy deal is coming to an end soon, don't wait to switch. If you do nothing, you will be transferred onto your supplier's standard tariff which will, in most cases, be more expensive.

Your energy provider has to send you a notification that your tariff is about to expire 42 to 49 days before it ends. From then, you are allowed to switch without having to pay any exit fee.
