Dual fuel energy is when you get your gas and electricity from the same supplier on one simple tariff. It can make managing your bills easier and may help you unlock cheaper combined prices compared to separate providers.
Switching your dual-fuel tariff could help lower your monthly energy bills using the CreditKnowledge compare and switch service, with no disruption to your supply. The process is quick and hassle-free — in many cases, you could switch in as little as five days, and your new supplier handles everything, including ending your old contract.
Compare dual fuel deals tailored to your postcode and quickly see where you could save. Choose a tariff that suits your budget and contract length, whether you prefer the stability of a fixed rate or the flexibility of a variable rate that moves with the market. Even prepaid meter customers can switch and access better value deals on both gas and electricity.
| Pros | Considerations |
|---|---|
| Simpler energy management: One supplier for both gas and electricity helps keep billing and account management straightforward | Not always the cheapest option: Savings aren’t guaranteed. Some single-fuel or separate supplier deals may work out cheaper depending on your usage and rates |
| Potential savings: Some dual fuel deals offer competitive combined rates or discounts when both fuels are bundled | Fixed contract commitment: Many tariffs require you to stay for 12–24 months, which may limit flexibility |
| Quick & simple switching: Switching is usually fast, with your new supplier handling the full process and no disruption to supply | Exit fees may apply: Leaving a fixed-term tariff early could result in charges, depending on your contract terms |
| One point of contact: Manage both fuels through a single provider for easier customer support | Pricing varies by supplier: Deals differ widely, so comparing options is important to find the best value |
Exit fees are charges some suppliers apply if you leave a fixed-term energy contract before it ends. They are most common on fixed-rate tariffs where you agree to stay for a set period, such as 12, 18 or 24 months.
If you’re on a Standard Variable Tariff, there is usually no fixed end date, meaning you can switch supplier at any time without paying an exit fee.
In many cases, suppliers also offer a short “switching window” near the end of your contract — typically the final 49 days — when exit fees may no longer apply.
Before switching, it’s worth checking whether your current tariff includes an exit fee, how much it is, and whether you’re close to the end of your contract. Even if a fee applies, switching could still be worthwhile if the savings on a new dual fuel deal outweigh the cost of leaving early.
