What is a dual fuel energy tariff?

Dual fuel means that your gas and electricity is supplied by the same energy provider.

It can be more convenient than having to deal with two separate suppliers, but it might not necessarily be the cheapest option – it's best to shop around and compare tariffs to find the right one for you.

Are dual fuel tariffs cheaper?

This depends. There are energy providers that specialise in supplying just gas or electricity who might be able to offer you a good deal too.

Typically most providers offer discounts if you get dual fuel, in the form of:

  • Cashback
  • A percentage off your bill
  • Cheaper energy unit rate per kilowatt hour
  • A lower standing charge

If you’ve stuck with the same supplier for a long time, chances are you’ll be on its standard variable tariff, so comparing dual fuel and single fuel options could help you save money and find a better tariff.

Are there any other benefits to dual fuel?

As well as potentially saving you money, there are a few other benefits:

  1. Less hassle

    You’ll be on one tariff for both gas and electricity, so you won’t have to spend more time doing your gas and electricity admin separately

  2. One point of contact

    As your gas and electricity is managed together, you’ll only need to contact one energy supplier, rather than two

  3. One meter

    You won’t need to have separate energy meters for your gas and electric

How do I make sure I’m getting cheaper bills?

Review your plan regularly, and compare it against other tariffs to check you’re on the best one. Consider that you might be charged a cancellation fee for leaving your contact before it ends.

Take regular meter readings to make sure you're being charged for what you use and no more.

If you’ve got a smart meter, it should take readings and send them to your provider for you. Read your bill carefully, and if the usage looks too high or low, contact your supplier to investigate.

Am I already on a dual fuel plan?

If you get your gas and electricity from the same supplier, but you’re not sure whether you’re on a dual fuel contract, the easiest way to find out is to check your energy bills or statements.
