This depends on the energy tariff you are currently on. If you have recently switched to a better energy deal, you may already be on the best tariff available to you, so you may not find many opportunities to save when comparing suppliers. However, if you haven’t switched gas and electricity suppliers for over a year, it’s likely you’ll be on a standard variable rate tariff, and comparing energy deals from other suppliers and switching could save you hundreds of pounds on your energy bills every year.
