Dual fuel energy means you get your gas and electricity from the same provider. It can be more convenient than using separate providers - and it’s often cheaper, though this isn’t guaranteed. 


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:



Bill cut

A percentage cut off your bill

Light bulb

A cheaper energy unit rate per KW hour

Lower standing charge

A lower standing charge

(the cost of having a gas and electricity supply)

Tariffs are constantly changing, so it’s important to compare your options to ensure you’re getting the best value for your money.

Aside from potentially finding a cheaper deal on energy, switching to a dual fuel tariff has other benefits: one bill, one direct debit and one point of contact.

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. The best deal depends å where you live, how much energy you use, and the products available at the time you switch.

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 – whether it’s a Big Six company or one of the smaller providers, we can help you find the best dual fuel deal for you.

The whole process is handled by the company you’re switching to, and guarantees you’ll switch hassle-free within 21 days, without any interruption to your supply.

If you decide you don’t want to switch, 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.
