Manage your energy with one provider
What is dual fuel energy?
Dual fuel energy means you get your gas and electricity from the same provider. It can be more convenient than using separate suppliers – and it’s often cheaper, though this isn’t always guaranteed.
If you get your gas and electricity from separate providers and receive separate bills for each, then you are not on a dual fuel tariff. Sometimes, this can mean more admin for you, and potentially the chance of missing out on the best value energy deals available right now.
It also means you can manage your whole household energy from one smart meter.
When searching for an energy deal with MoneySuperMarket, you can choose to search for dual fuel or single fuel tariffs and see where you can make energy savings.
Why switch to a dual fuel tariff?
There are many reasons why you might want to switch to a dual fuel tariff.
-
It’s more convenient
Instead of having to deal with two separate bills from different companies, you’ll just get bills from one. You can even get a combined bill, which gives you a better idea of your energy usage and costs
-
One point of contact
You’ll only need to get in touch with one energy supplier if you have any questions. And you can manage everything through one account
-
Discounted energy prices
You might be able to save some money, as some providers may offer a dual fuel discount
-
Easy to switch
Switching to a dual fuel tariff is a quick and easy process. Once you’ve found a deal you like, it’s a simple case of filling out a form with your details and letting the energy companies handle it

How does dual fuel energy work?
Many energy providers offer discounts to customers who take out a dual fuel tariff, but the saving will usually only represent a small percentage of your bill. You could receive these discounts in the form of:
-
-
A percentage cut off your bill
-
A cheaper energy unit rate per KW hour
-
A lower standing charge
(the cost of having a gas and electricity supply)

Which energy suppliers offer dual fuel tariffs?
In general, most energy suppliers offer dual fuel deals. This includes big name fuel suppliers such as:
EDF Energy
British Gas
Octopus Energy
Any household that uses both mains gas and mains electricity can qualify for a dual fuel tariff.
Can I get a fixed rate dual tariff?
Generally, yes. Whether you’re paying via direct debit or paying bills every quarter based on your usage, you can get a fixed rate dual tariff.
Because of the rapid rise and fluctuation in energy prices in recent years, many consumers have not been able to switch to fixed tariffs. As prices begin to ease, however, many suppliers are now offering the chance to switch to a fixed rate dual tariff instead of having to use the often more expensive standard variable tariff.
Sometimes, these deals are only available to existing customers, although more and more fuel suppliers are now offering fixed tariffs. Switching to a fixed rate will help you budget better and minimise the cost of energy in the medium term.
Some suppliers will ask that if you lock into a deal for 12 months that you pay an exit fee, sometimes around £50, to change suppliers.
What environmentally friendly dual fuel deals are available?
An increasing number of providers offer environmentally friendly dual fuel deals, designed to lower your carbon footprint.
Octopus Energy is an example of a supplier that gets all its electricity from renewable sources, while it offsets all the emissions from the gas it supplies, making it one of the best providers of green energy.
Many other suppliers also offer ‘green’ dual fuel tariffs that work in a similar way, though they may cost more than their regular tariffs.
Switching your energy supplier?
You can be with your new supplier within five working days (provided you chose to fast track your switch). There'll be no interruption to your switch and all the admin is handled by your new provider, so all you need to do is compare and go.

Pros and cons of dual fuel energy
-
What are the pros of a dual fuel tariff?
It’s easier to manage – you won’t have to deal with your gas and electricity separately, saving you time and effort
Discounted deals – some energy suppliers may give you a discount for bundling your gas and electricity together
-
What are the cons of a dual fuel tariff?
It’s not always the cheapest option – depending on the supplier, you might find that single fuel tariffs work out cheaper for you than dual fuel tariffs
Early exit fees – if you have a fixed-rate dual fuel tariff but want to switch to another supplier before your deal ends, you’ll have to pay an exit fee for leaving early
What other options are available for cheap energy bills?
If you are concerned that your energy supply is too expensive and are keen to explore energy savings, you may want to consider a few options:
Install renewable energy sources, such as solar panels or a heat pump. Although these are costly initially, they can save you hundreds in the long run, with the possibility to sell your excess energy back to the National Grid.
Explore supplier and support schemes. If you are struggling to pay your energy bills, speak with your supplier. They may be able to put you on a cheaper tariff. Some government schemes can help those on benefits with their energy bills. Read more about how to get help with your energy bills in our comprehensive guide.

Are dual fuel tariffs always cheaper?
Sometimes – but not always. You may find that a dual fuel plan is cheaper one year, and a single fuel one is cheaper the next year. Remember that Ofgem's energy price cap means there's a limit to how much your energy can cost, regardless of which tariff you choose.
The best thing to do is to regularly review your energy plan, compare it to other tariffs and shop around.
Be aware, though, that right now it's best to stay put with your current tariff. This is because there aren't any deals available to switch to.
Is dual fuel cheaper than buying gas and electricity from separate suppliers?
Dual fuel tariffs can be cheaper than buying your gas and electricity from separate suppliers, but this isn’t always guaranteed.
If you look closely at all the possible energy providers, you may find the cheapest option is to get your gas from one supplier and your electricity from another. It depends on where you live, how much energy you use, and the products available at the time you switch.
When switching becomes available again, it’s always a good idea to compare energy tariffs by looking at both dual fuel deals and separate suppliers, before making a decision.
Do all energy suppliers offer dual fuel tariffs?
Most energy suppliers offer dual fuel deals but it’s totally up to you whether you choose to switch to dual fuel or stick to a single tariff.
How do I know if I have a dual fuel or single fuel tariff?
If you get both your fuels from the same supplier, but you're not sure whether you're actually on a dual fuel tariff, the easiest way to find out is to check your energy bills or statements. Alternatively, call your supplier to find out.
If you currently get your gas and electricity from two different suppliers, you’re definitely not on a dual fuel contract.
Is it easy to switch to a dual fuel energy tariff?
It’s quick and easy to switch to a dual fuel tariff thanks to the energy switch guarantee. But before you switch energy suppliers, it’s always best to compare your options. With MoneySuperMarket, you can compare gas, electricity and dual fuel tariffs from a range of suppliers, from Big Six companies to one of the smaller providers.
The whole process is handled by the company you’re switching to, and guarantees you’ll switch hassle-free with no interruption to your supply.
If you opt to fast track your switch, you should be with your new supplier within just five working days.
Alternatively, if you opt to wait until the end of your 14-day cooling-off period to complete the switch you should be switched over on the fifteenth day.
Whichever option you pick, you can cancel within 14 days and stay with your old provider. If you do switch, you’ll get any credit on your old account back within 14 days of your last energy bill.
If you’re on a fixed-term deal and you choose to switch, there may be an early cancellation fee involved with switching before the end of the term.
How can I find a cheaper dual fuel deal?
You can try to find a better deal by running a comparison with us. You'll able to compare quotes by the type of rate you’ll be on and the estimated cost per year and per month.
What is a standard variable tariff?
A standard variable tariff is a tariff which rises and falls depending on the wholesale price of energy. It is almost always more expensive than a fixed rate energy tariff, so it is a good idea to compare deals to see how much you can save by switching to a fixed rate deal.
How can I find the best dual fuel deal?

Does MoneySuperMarket work with all the providers on the market?
No, not every company can be included in our service. This is because some companies don’t want their products included on comparison sites, and some decide that they would rather not pay a fee.
