Why should I compare dual fuel energy deals?

Most energy customers in the UK are on dual fuel plans, which are offered by the vast majority of energy providers. To save money and make sure you’re on the best deal, it’s important to compare dual energy deals on a regular basis and make the switch whenever you find something better than your current plan. You can do so by entering your postcode above, which will take you into the Uswitch energy experience and allow you to compare the fixed energy deals currently available.

On TrustPilot, Anthony Shopland described his experience:

"Dual fuel energy tariff ending with Scottish power. Had a really bizarre quotation increasing my monthly DD by £30+ a month based on my actual usage. Rang them to try and get some clarity, 47 minutes on hold - eventually saved £240 a year by going with Shell."

What is dual fuel energy?

Dual fuel tariffs provide your home with gas and electricity from a single supplier in one combined package. Most UK households can be put on a dual fuel plan.

Why pick a dual energy deal?

First, and foremost, dual energy plans are convenient. Instead of having to deal with two suppliers with separate tariffs, bills and payments for electricity and gas, you consolidate them into one, with the added bonus of having a single point of contact for all your energy needs.

In addition, suppliers usually offer incentives that make dual fuel tariffs better value than getting your gas and electric separately – but this is not always the case. These incentives can include:

  • Cashback

  • Discount on your bill for taking two fuels on one plan

  • Cheaper energy unit rates

  • Lower daily standing charge

Note, however, that there may be times when sourcing gas and electricity from different suppliers works out cheaper. You can also compare electricity-only plans and gas-only plans to see if this is currently the case.

What’s the cheapest dual fuel deal?

The cheapest dual fuel tariffs will be different for everyone - there’s no one-size-fits-all option. To make sure you’re getting the best gas and electricity deals, you should run an energy comparison on both dual fuel and single fuel tariffs using the information about your current usage to get the most accurate results.

Who is the cheapest dual fuel supplier?

Again, there’s no definitive answer as prices will vary by tariff, where you live, and time of year. Energy suppliers are constantly reviewing their prices, and this includes keeping an eye on their competitors to ensure they’re offering competitive deals. The cheapest dual fuel supplier for you today may be different tomorrow.

How much could I save with a dual fuel tariff?

That will depend on your individual circumstances, including the current tariff you’re on – which is why it’s important to compare both dual fuel and single-fuel plans when looking to save money and potentially switch supplier.

If you’re currently on your supplier’s default variable rate tariff, then switching to a dual fuel, fixed-rate tariff will in most cases save you money. If you’re currently on a fixed-rate tariff that’s about to end, then beware ending that tariff without finding another – Ofgem recently increased the energy price cap by £96, and standard variable tariffs are more expensive than before. In April 2021, Uswitch revealed that 1.3 million households faced price rises of up to £319 a year if they didn’t switch after their current fixed-rate deals came to an end.

What are the best dual fuel deals for pensioners?

There are no specific dual fuel deals for those of retirement age, but you can save money by looking at fixed-rate tariffs, which guarantee the price of your energy for a set period. Other ways to save money on your energy tariff is to choose a dual fuel deal, which tends to be cheaper, and to pay by monthly direct debit as suppliers usually offer discounts for this type of payment plan.

You can also receive assistance with paying bills during the colder winter months depending on your circumstances – check out our guides to the Winter Fuel Payment, Warm Home Discount and Cold Weather Payment schemes to see if you’re eligible.

Which suppliers offer dual energy deals?

The vast majority of suppliers – 48 out of 55 in September 2020, according to Ofgem – offer dual fuel plans, including the big six energy providers.

Note: many of these suppliers also offer gas-only and electric-only plans too, which is why it’s important to compare them all to see which is the best for your needs.

Can I get a smart meter with a dual fuel tariff?

There’s no reason you can’t have a smart meter just because you’re on a dual fuel tariff. Some providers even offer cheap dual fuel deals on the basis that you have a smart meter installed. 

Changing to a dual fuel plan shouldn’t make any physical difference to your home - you’ll continue using the same gas and electricity meters, except you’ll only have to submit meter readings to one provider from now on – although if your new plan comes with a smart meter, it should do that for you automatically.

Duel fuel energy FAQs

Usually the answer is yes, but you should always run a comparison to be sure. Fixed-rate energy plans lock you into a long-term contract, usually one or two years, and you will pay the same unit price for that period, which means there won’t be any nasty surprises lurking in your bills, although you should remember your bills will still vary from month to month based on your usage (typically higher in the colder winter months, and lower in the summer when you use less energy).

Variable rates are tied to the wholesale cost of energy, which vary over time and lead to regular unit price changes that introduce more volatility to your bills. Just because you’re not on a fixed rate doesn’t mean you’re not getting a good deal, though. Brands like Bulb have become popular due to the fact they offer a single, straightforward variable-price tariff for both pay-monthly and prepayment users.

Yes, but there are some limitations. Green electricity is widely available and even comes as standard on many plans, including those from major providers such as E.ON. Smaller providers have also made a name for themselves by providing green energy, though if you want 100% green electricity and gas, your options become limited as green gas is far harder to generate.

Yes, you can get dual fuel plans for prepayment energy meters. Bear in mind, though, that prepayment energy is almost never the cheapest option. If you’re able to pay by direct debit, then fixed rate plans are significantly better value.

Yes, generally fixed rate plans that last a year or more and are paid by direct debit will earn you much better savings. As we’ve said, though, there are some great value variable plans out there, but if securing a good unit price that won’t change during the duration of your tariff is a priority, then fixed price is definitely the best route to take.

If you have one fuel coming from one provider and want your second fuel to join it, this is easily done. If you are on a variable tariff or within 49 days of the end of your fixed price plan you can do this at any time without having to face energy contract exit fees. 

Apart from savings, dual fuel customers aren’t usually privy to any perks that single-fuel customers can’t get. 

If your house doesn’t use gas, then you won’t be able to get on a dual fuel plan. If you don’t have gas-powered central heating, use a gas cylinder for cooking or have an electric stove and oven, then it’s not a problem – you simply need to search for electricity deals only.
