Martin Lewis has urged anyone on a certain type of energy bill contract to 'check now' if they feel like they're suddenly paying more than they should.
The finance guru is known for helping the people of the UK out with their money worries, especially in the past few years, when the cost of living has skyrocketed and many are struggling.
Energy bills are a particular worry for a lot of people, and for those on a fixed contract, Martin says it's worth checking a few small details - as you could end up paying less.
