If you’re on a dual fuel tariff, this means you get your gas, electricity, and all associated energy bills from the same supplier.
Energy companies will often offer a discount for customers who take on both gas and electricity contracts with them, meaning a dual fuel tariff can work out cheaper than getting your gas and electricity from separate suppliers.
Dual fuel is usually offered as a variable, fixed, or online tariff, so you’ll need to compare everything on offer to work out which is the best deal. If you don’t mind dealing with two suppliers, it’s worth comparing dual fuel and single fuel deals, to work out which will save you the most money.

There are a few good reasons why it’s worth considering getting your gas and electricity from the same supplier, the most obvious one being because it’s often more convenient to receive bills from just the one company, which may come as a combined, itemised bill.
If you have any complaints or questions, you only have to deal with the one energy supplier.
Then there’s the dual fuel discount, which most energy suppliers offer as an incentive for you to use them for both your gas and electricity.
These discounts are usually applied directly, meaning the money will come straight off your monthly or annual bills, but be aware these discounts change from time to time and may vary for each tariff so always check the tariff details before applying.
Anyone can switch from a single fuel to a dual fuel tariff, and vice versa – just run a home energy comparison as normal, remembering to compare both gas and electricity together.
If you’re on a prepayment meter, you can still make the switch to dual fuel. Again, just run a price comparison as you usually would.
To get the most accurate results when running a comparison, you need to enter details of your household energy usage, but you’ll still be able to run a comparison even if you don’t have this information to hand.
Then simply review all the available options, pick a tariff that best suits your needs and your budget, before confirming the switch online.
You can either switch to a dual fuel deal with your current supplier or move across to a new supplier, but you’ll need to look out for exit fees, which you’ll have to pay on both your gas and electricity tariffs.
Even if you’re switching from one dual fuel deal to another, you’ll still have to pay an exit fee on both fuels.
Once you’ve chosen the best deal, we’ll send your change of supplier details through to your old provider, and pass your information on to your new one, who will then get in touch to confirm the switch.
Although you don’t need to do anything else, it’s worth contacting your old supplier with a final meter reading to make sure your final bill is accurate.
The switch should take no longer than 17 days to go through - three days for the switch, followed by a 14-day cooling off period – and remember, there’s no need for any drilling or work at your property as your gas and electricity will be supplied through the existing pipes and cables.
