If you don’t want to switch energy suppliers, you still might be able to find a cheap gas and electricity deal with an energy tariff. If you haven’t switched energy before it’s likely that you’re on your provider’s standard variable or default tariff, which is typically the most expensive type of plan on offer. You can use an energy tariff to switch to a cheaper energy deal from your current provider if you’re happy with the service but want to save on your energy bills.
