Here we’ll take a closer look at Dual Fuel Tariffs, compare different tariffs from a range of suppliers, and answer some of the most frequently asked questions about these kinds of tariffs.

So you can make an informed decision for your household.

What is a Dual Fuel Tariff?

A Dual Fuel Tariff is when your gas and electricity are both supplied by the same energy provider. Many people use different suppliers for different utilities, and (quite understandably) suppliers are keen to provide both fuels to their customers. And are prepared to offer them more attractive tariffs to incentivise them.

In terms of service, you won’t notice any discernible difference whether you’re on a Dual Fuel Tariff, or getting your gas and electricity from different suppliers. All suppliers distribute the same energy through the same network of wires and pipes. The only thing you’ll notice is the difference in price.

Which is why it’s so important to find the right supplier and the right tariff for your needs. At Switch Plan, that is our speciality. Let our experts scan the UK energy market for you. All you have to do is give them a call at the number above!
