We cover all suppliers of gas and electricity licensed to supply domestic consumers in Great Britain. In addition we also cover some of the main unlicensed suppliers. We cover all current tariffs from these suppliers across all the main energy payment methods. In this way we show you all the best deals currently available to you. As a general rule, we do not cover 'historic' or 'preserved' tariffs. These are energy tariffs where the price has been fixed at a given level because, for example, it was offered with a price guarantee for a certain period of time. These tariffs are no longer available to you, so you will not be able to apply for them.
