What is the best way to make savings?

The energy market is changing constantly, so getting a quote every 12 months or when your contract is about to end will ensure you stay on top of the market and don't miss out on a competitive deal.

Which? Switch customers have saved up to £300 a year by switching either tariffs or energy suppliers. Read their stories to find out how simple it was for them.

Here are a few more pointers:

• Understand the different types of energy tariffs available - the cheapest deals are often online discount or variable rate tariffs.
• Energy companies will often offer extra discounts if you take both gas and electricity from them as part of a dual fuel deal.
• Your energy company should give you a choice of ways to pay your energy bills - but the cheapest option is often direct debit.
