What is dual fuel?

Dual fuel energy tariffs combine gas and electricity into one service from the same supplier, which means that customers only have to deal with one company and pay one bill every month or quarter. An increasing number of customers who do need to use both gas and electricity, as opposed to one or the other, are opting for dual fuel tariffs to make their lives easier. It’s now easier than ever to get a dual fuel quote from the big six suppliers or the smaller brands on the market.

What are the benefits of a dual fuel tariff?

Choosing a dual fuel tariff might also mean that customers pay slightly less than those who get their gas and electricity separately. For instance, some dual fuel suppliers may offer a specific dual fuel discount at the start of the plan as an incentive to new customers. This might not be the case for all customers, so it’s always worth using your current usage and plan details to check what you might be able to sign up to.

Additionally, as far as life admin is concerned, one of the key benefits of dual fuel tariffs revolves around the ease and convenience associated with dealing with just one supplier, as mentioned above. You only have one point of contact and one bill to deal with every month, which will greatly reduce the time it takes to resolve any issues or work out how much you can expect to spend on your energy in a given month or quarter.  

Are dual fuel energy tariffs cheaper?

Dual fuel tariffs, like any tariff, have every chance of being the cheapest option on the market for any energy customer. It largely depends on their energy usage and the amount they’re currently spending on their energy. Dual fuel tariffs can sometimes be cheaper because combining fuels and reducing admin costs associated with those tariffs means that suppliers can afford to charge a little less in order to entice customers into choosing one. However, it’s worth remembering that if you want to leave a dual fuel tariff early, you’ll be charged early exit fees for both fuels as opposed to just one, and you’ll be vulnerable to price hikes for both fuels if you’re on a non-fixed deal and the supplier decides to increase the amount it charges its customers.

The best way for you to work out if dual energy tariffs are cheaper than the deal you’re currently on is to ensure you’re entering accurate information into price comparison websites when you search for new deals, as this will enable systems to find the best matches for you.

How to compare dual fuel prices and switch to a new energy supplier

When you come to compare dual fuel prices, the most important pieces of information you need to know are exactly how much energy you currently use and exactly which plan you’re currently on. Price comparison websites will always ask for the details regarding your current energy usage so they can work out how much you’re likely to spend in the next year. They also need to know which plan you’re on when it comes to the fuels you use and the meter type you have, so the more accurate you can be in terms of what you tell them, the better. This will allow them to match you with the most suitable deals to make your decision as easy as possible.

The information you need can usually be found on one of your bills (the latest bill you received is the best one to use). Energy bills can be notoriously difficult to read, so once you’ve found the information you need, write it down somewhere to refer to it if you need to. Once you’ve been presented with the potential dual fuel deals you could switch to, you can use filters that take other factors like billing, exit fees, potential incentives and more into consideration to help you find the best possible dual fuel plan. From there, it’s a simple task to fill in your personal details and confirm your switch, which should be completed within 21 days as part of the Energy Switch Guarantee.
