Compare Dual Fuel Deals

If you’re looking for an easier way to manage your household energy, a dual fuel deal could be the answer. By getting both your gas and electricity from one supplier, you could save money, simplify your bills, and make switching energy providers even easier.

With Simply Switch, it’s easy to compare dual fuel tariffs by area and usage so you can get the best rate for your home in just a few minutes.

What Is a Dual Fuel Tariff?

A dual fuel tariff indicates that you derive both your gas and electricity from the same energy supplier. Instead of managing two separate accounts, you will receive one combined bill; many suppliers offer dual fuel discounts to incentivize customers.

Why some households prefer dual fuel

• One supplier, one bill, and one direct debit for convenience.
• Potential discounts for taking both fuels together.
• Easier communication and fewer account logins or reference numbers to track.

When dual fuel isn’t an option

Not all energy providers supply both fuels: some are electricity-only or specialize in green tariffs that may not cover gas. You may need separate suppliers in these cases, but you can still compare the total annual cost through Simply Switch to see which option works best.

Is Dual Fuel Cheaper Than Separate Suppliers?

In most instances, dual fuel can be cheaper owing to supplier discounts and the simplicity of managing both fuels together. However, this is not always guaranteed to be cheaper.

When dual fuel wins

• You qualify for a dual fuel discount or bundled offer.
• You value convenience and one combined bill.
• You want a single point of contact for queries and service.

When separate suppliers might be cheaper

• You find an electricity-only tariff or gas-only tariff offering a better rate.
• You want to mix and match green electricity with standard gas.

It is best to compare these two options side by side; Simply Switch will calculate your total annual cost whether you choose one supplier or two.

Fixed vs Variable Dual Fuel Tariffs

When you compare dual fuel deals, you are usually presented with a choice between fixed and variable tariffs.

Fixed tariffs

• Your unit rates and standing charges stay the same for the length of the contract.
• Offer price certainty and easier budgeting.
• May include exit fees if you leave early.

Variable tariffs

• Prices can go up or down in line with wholesale energy markets.
• Usually no exit fees, offering greater flexibility.
• Good if you expect prices to fall or don’t want to commit long-term.

What to Check Before You Switch

Before you confirm your new deal, take a few moments to check the key details:

• Exit fees and contract end date: Be clear about any charges for exiting your current deal before the end date.
• Unit rates and standing charges: Check both gas and electricity rates, not just one.
• Length of the contract and discount terms: Some dual fuel discounts apply for a fixed period only.
• Green options: If sustainability matters to you, look for renewable or carbon-offset tariffs.
• Supplier ratings: Customer service and reliability can make a big difference over time.

By comparing these side by side, you’ll know exactly what you’re signing up for.

Will My Energy Supply Be Interrupted?

Switching to a different supplier will not affect your energy supply in any way. You will continue getting gas and electricity through the same pipes and wires, no matter who your supplier is.

Once you confirm your switch, your new supplier handles the entire process.

• Typical switch time: around five working days.
• You’ll have a 14-day cooling-off period to change your mind without penalty.
