What is dual fuel?

A dual fuel tariff is an energy plan that offers consumers a discount on your energy when you get gas and electricity from the same supplier. Most energy suppliers offer dual fuel tariffs, and choosing the perfect plan for your needs can increase your energy savings. So you’ll have more disposable income to spend on fun stuff. At Papernest, we’re passionate about helping you to find the perfect energy plan for your needs, as well as helping you to decide which energy plan best suits you.

What is a Dual Fuel energy tariff?

What are the benefits of a dual fuel tariff?

Most energy consumers would benefit from looking into a dual tariff either from their current supplier or even a brand new supplier.

Most energy companies are keen to offer dual fuel tariffs to their customers. The energy market is highly competitive, with dozens of suppliers of all shapes and sizes fighting for customers. It stands to reason that suppliers want to incentivise their customers to choose them to supply all of their energy rather than just 50%.

There are potential benefits of a dual fuel tariff:

  • Most of the time it works out cheaper for consumers.
  • Longer-term dual tariffs may offer special promotional rates.
  • There are all kinds of dual fuel tariffs to choose from, including cost-effective paperless and online tariffs as well as 100% green energy plans.

Is there a downside to a dual fuel tariff?

While dual tariffs don’t necessarily have a downside, they may not always be the best fit for every home. Under some circumstances, it may be cheaper to get your fuels from separate suppliers. The Papernest team will always scour the market to find the best energy deal/s for your household’s unique needs.

Are there any other benefits to dual fuel?

Cost savings are not the only way in which consumers can benefit with a dual tariff. They are also beneficial because they make consumers’ household finances a little easier to manage. Because they only have to worry about one energy bill rather than two, it’s easier to accommodate the cost within your household budget.

Let’s face it, we could all do with fewer direct debits coming out of our bank accounts. If a dual fuel plan can give you better prices and simpler bills, they’re pretty much a no-brainer!

How much is the dual fuel discount?

This varies between suppliers. Most will offer a dual fuel discount as a percentage, while some will reduce your direct debit by a flat rate for the year. Trawling the energy market for the best dual fuel discounts can be time-consuming. Fortunately, the Papernest team are here to search for the best dual fuel rates on your behalf.

£20-£30 is a fairly typical discount range for dual fuel discounts.

Are dual fuel energy tariffs cheaper?

Dual fuel energy tariffs are usually cheaper. And because there is a huge range of different types of dual plans you can usually find one to suit you. However, a dual fuel tariff isn’t always necessarily the cheapest deal for you. The best plan for your needs depends on a range of factors including your location, your usage and what kind of meter you have.

That’s why we check both single and dual fuel tariffs to ensure that you get the perfect energy plan for your unique needs.

How do dual fuel tariffs work?

Dual fuel tariffs are simple to manage, as the supplier calculates your discount for you on your behalf when you sign up. The discount is deducted from your energy quote for the year, and split across your direct debits. So whether you pay monthly or quarterly, you can still benefit from the discount.

Do all energy suppliers offer dual fuel tariffs?

Most energy suppliers offer at least one tariff with a dual fuel discount for customers. However, some suppliers only offer a single fuel and are thus unable to offer dual fuel discounts. Zog Energy (a gas-only) supplier is one example. Moreover, there are some suppliers like Bulb that no longer offer a dual fuel discount for the sake of making their energy plans simpler.

Still, over 40 of the 50-plus energy suppliers on the market offer at least one dual fuel energy plan.

Which dual energy supplier is best for 2021?

This is a tricky question to answer, as the best supplier and dual energy tariff will depend on your location, your meter type, how much energy your household uses and when. However, if we average out energy consumption and unit prices and standing charges throughout the country we can identify 10 of the best value dual-fuel tariffs on the market.

For each we have provided monthly and annual costs as well as how much you could save in comparison to the Ofgem energy price cap. At the time of writing this is set at £1,042 per year for both fuels. However, this is likely to rise in April 2021. Estimated costs assume UK average consumption of 2,900 kWh of electricity and 12,000 kWh of gas per year.

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

Of course, most of us choose our energy suppliers on the basis of cost. Why pay more for your energy when one supplier’s gas and electricity is indistinguishable from another’s? However, there are other metrics that you may want to consider when choosing an energy supplier:

Customer service

Cheap energy is great. But when something goes awry with your supply or bills, it can be extremely frustrating when you can’t get the support you need. Some cheaper dual fuel energy tariffs are online-only tariffs, meaning that you can only get online support rather than through a call centre. Choosing the perfect dual fuel plan means choosing a supplier that not only offers great prices but superb customer service.

To see how various energy suppliers rank by customer service, take a look at the Citizens Advice website.

Dual Fuel energy tariffs


Eco-conscious energy consumers will want to choose a dual-fuel tariff that offers 100% renewable electricity. There are also suppliers that combine this with either carbon-neutral or carbon-offset gas. Carbon-neutral gas is biomethane gas made from farm, plant and animal waste rather than natural gas from the ground. Carbon-offset gas is where the carbon generated from sourcing the gas is offset by carbon-neutral or negative initiatives that the supplier carries out within the UK and all over the world.

The following suppliers provide green dual-fuel tariffs:

  • Bristol Energy
  • Click Energy (only available in Northern Ireland)
  • Co-Op Energy
  • Ecotricity
  • ESB Energy

How else can I ensure cheaper energy bills?

Choosing the right dual fuel energy plan is a great way to save on your energy bills. But that’s really just the tip of the iceberg. There are all kinds of ways in which you can ensure cheaper energy bills, from making energy-saving renovations to your home to simple vigilance. For instance, something as simple as turning your thermostat down by just one degree could save up to £75 per year on your heating bill.

In the table below, we’ve compiled a list of energy saving solutions both large and small that can significantly reduce your energy bills.

Energy Saving Solution Potential Savings
Turning down your thermostat by just one degree. £75 per year.
Using CFL or LED bulbs instead of incandescent bulbs. £55 for the lifetime of each bulb.
Replace your windows or doors with BFRC A++ rated alternatives. £120 per year.
Replacing your loft / cavity wall insulation. Up to £395 per year.
Replacing your boiler if it’s more than 12-15 years old. Up to £305 per year.
Switching off any devices that are left on standby overnight. £68 per year.

Dual rate savings

If your property has a dual-rate electricity meter like an Economy 7 or Economy 10, you can make even more savings by using more cheap off-peak energy. Off-peak hours depend on your location, however they are usually between 11pm-12:30am and 6am-7:30am. Of course, many households are sound asleep within these hours. Nonetheless, they are the perfect time to reduce your energy bills by:

  • Charging phones, tablets and laptops
  • Using your washing machine or dishwasher
  • Warming up underfloor heating so that it’s ready for the morning

If your devices have a timer you can program them to activate while you’re tucked up in bed. So you can sleep soundly knowing that you’re saving even more money on your dual fuel energy bills.

Smart thermostats

Heating your home makes a huge contribution to your energy bills in the winter months. But with a smart thermostat, you can take control of your home’s temperature, no matter where you are. What’s more, over time your smart meter will learn your family’s movements in order to transfer heat through your home more efficiently, allowing you to achieve the perfect balance between comfort and cost-efficiency. A smart meter costs around £260 including professional installation. But they can generate savings of up to £350 per year.
