We’re really sorry, but we can’t compare energy deals at the moment.

Until then, you could still save on your other household bills when you compare quotes with us.

What is dual fuel energy?

Dual fuel energy means you get your gas and electricity from the same supplier. It could save you money and can be more convenient than using separate suppliers, leaving you with one bill and one point of contact. Dual fuel deals don’t always turn out cheaper than having separate energy providers though.

Are dual fuel energy tariffs cheaper?

While it often can be, a dual fuel deal isn’t always cheaper than buying your gas and electricity from separate suppliers.

Some energy suppliers offer a discount for taking both gas and electricity from them, although sometimes the saving is small compared to your overall bill. Tariffs constantly change and this means it’s important to conduct a comparison of the offers available to you. For example, in one year, taking two separate single fuel plans could be best, but, 12 months later, it might be smart to switch to a dual fuel option.

How do dual fuel tariffs work?

Getting a dual fuel tariff simply combines your gas and electricity with one supplier. Rather than having two separate bills come through, you’ll just have the one to manage, making it easier life admin for you. You’ll normally get some sort of discount for combining the two supplies, which can make dual fuel tariffs cheaper than going separately, but this isn’t guaranteed.

How much could I save with a dual fuel tariff?  

You shouldn’t assume dual fuel is the cheapest option. The key is to compare all the tariffs available and find one that’s right for you – dual fuel or not.

Why switch to a dual fuel tariff?

There are two main reasons people often choose a dual fuel tariff:

  • Less hassle – having your energy supply combined is easier to manage. Your bills are combined so you have a clearer idea of what you’re using and how much it costs. Plus, it also means one quote and depending on the tariffs available at that time, you could also benefit from a saving.
  • One point of contact – if you have an issue with your supply or bill, having one supplier can make this easier to raise issues or make changes to your service.

Do all energy suppliers offer dual fuel tariffs?  

As of June, 2020, 49 suppliers provide both gas and electricity, and five supply only gas and two electricity, so you shouldn’t feel obliged to go down the dual fuel route if it doesn’t make financial sense to do so. You can get different quotes and decide to switch to single or dual fuel tariffs, whichever you prefer.

How do I find out if I have a dual fuel tariff?

If you’re not sure you’re on a dual fuel tariff, the first thing to check is who your energy supplier is. If your gas and electricity are through the same supplier, there’s a good chance you’re on a dual fuel tariff, but it’s not certain. The best, and most simple, way of finding out if you’re on a dual fuel tariff, is to simply check your most recent energy bill. The name of your tariff will be included on your statement, so you should be able to tell if you’re on one from that. If you’re still in doubt, just call your supplier and they’ll be able to tell you.

Is it easy to switch to a dual fuel energy tariff?  

Switching to a dual fuel deal is straightforward. When you compare energy suppliers with us, just choose the option to compare both gas and electricity. We’ll show you a list of dual fuel plans available to you. Once you’ve chosen your tariff, it’s just as easy as switching your suppliers individually – or easier, because you only have to do it once.

There’s no complicated paperwork involved and the process will take place without any interruption to your supply.

Do note, however, that if you’re on a fixed term deal, there may be early cancellation charges involved with switching before the end of the term. We make it easy for you by showing you any applicable exit fees as part of your results, so you can make the right decision about when to consider switching your energy tariff.  

How can I find the best dual fuel deal?

The best dual fuel deal isn’t really a one-size fits all. Each home uses a different amount of energy, and where you live can also affect your energy price. Energy is a market which rarely rewards loyalty, so one of the best ways to get a better deal on your energy is to switch regularly and take advantage of new deals. Getting on a fixed-rate tariff is a quick and easy way to save money, so don’t let yourself slip onto a variable-rate tariff, as you’ll likely end up paying more than you need to.

However, with so many suppliers out there, finding a better deal for energy can seem daunting. That’s why, at Compare the Market, we aim to make life simple. With just a few details about you and your energy usage, we bring you deals from a wide range of energy suppliers. This makes comparing dual fuel deals easy to manage, all in one place.

What else should I look for when comparing dual fuel deals?

If you’re looking for the best dual fuel deal, there are range of things that may be important to you:

  • Price – for many this is the number one thing, and by comparing dual fuel deals, you can easily sort your results by the cheapest price to find a better deal.
  • Supplier ratings – if something went wrong with your supply, or you needed to contact your provider for any reason, it’s important to know that your supplier has a good reputation for their service. We include supplier ratings in our comparison service, allowing you to weigh up the benefits. The cheapest quote presented to you may have a lower supplier rating than the next one, so you may decide to pay a little extra.
  • Greener energy – if you’re environmentally conscious about your energy usage, you might want to choose a supplier who specialises in greener energy sources to minimise your carbon footprint.
  • Exit fees – if you’re locked into a contract with a supplier and a better deal comes along, you will want to know how much it will cost you to free yourself from your existing deal. We show the exit fees for all our compared deals, so you know exactly how much it could cost you if you decide to leave early.
  • Contract length – while a price might be lower, it may tie you into a longer deal which may restrict you from switching if a better deal comes along later, forcing you to pay your exit fees.
