Discover the UK's leading dual fuel providers. Our expert guide helps you compare tariffs, simplify your energy bills, and find potential savings by switching suppliers.
Understanding Dual Fuel Energy
Managing separate gas and electricity bills can be an administrative burden. A dual fuel tariff offers a streamlined solution, combining both services with a single supplier. This approach not only simplifies household finances but can also unlock discounts, making it a popular choice for UK consumers seeking efficiency and potential cost savings. This guide will help you navigate the market and identify the best providers for your needs.
Is a Dual Fuel Tariff Right for You?
This guide is for any UK householder who wishes to consolidate their energy bills into one manageable payment. If you are looking to potentially reduce your annual energy costs, simplify your paperwork, or find a new supplier with better customer service, understanding the dual fuel market is an essential first step.
Decoding Your Energy Options
Before comparing providers, it is crucial to understand the key terms associated with energy tariffs. A dual fuel plan simply means you receive your gas and electricity from the same company.
Key components of a tariff include:
- Unit Rate: The price you pay for each unit (kWh) of gas or electricity you use.
- Standing Charge: A fixed daily amount charged by your supplier to cover the costs of supplying energy to your property, regardless of your consumption.
- Tariff Type: Deals are typically offered as ‘fixed’ or ‘variable’. A fixed tariff locks in your unit rate for a set period, protecting you from price rises, while a variable rate can fluctuate with the market.
Combining services under one provider simplifies billing and account management, saving you valuable time and effort. While not always the absolute cheapest option, the convenience and potential for discounts make it an attractive proposition.
Leading Dual Fuel Providers in the UK
The UK energy market is competitive, with a mix of large, established suppliers and smaller, agile challengers. Customer service and price are often the deciding factors.

This makes it a compelling choice for those prioritising a positive customer experience. Other major providers like British Gas and E.ON also offer competitive dual fuel tariffs.
Here is a comparison of some notable providers:

For those focused purely on price, comparison sites like FreePriceCompare can list the top 20 cheapest dual fuel tariffs available, featuring both large and small suppliers.
The Financials of Combining Your Energy
The primary motivation for many when considering a dual fuel tariff is cost reduction. Suppliers often provide a small annual discount as an incentive for taking both fuels. However, it is essential to understand that the most significant savings typically come from switching suppliers, not just from bundling.
Always compare the cost of a dual fuel tariff against the best separate deals for gas and electricity. Sometimes, using two different suppliers can result in a lower overall cost.
Be vigilant about exit fees. If you are on a fixed-term deal, leaving early to switch to a dual fuel plan could incur a penalty that negates any potential savings.
The best way to determine the financial impact is to use a whole-market comparison tool, such as those offered by MoneySavingExpert or Uswitch. These platforms analyse your specific usage and postcode to provide accurate, personalised cost projections.
Are You Ready to Make the Switch?
Most UK households are eligible to switch energy suppliers. You can switch if:
- You are on a standard variable tariff.
- Your fixed-term contract is ending within the next 49 days.
- You are willing to pay an exit fee to leave your current fixed deal early.
To get started, you will need some basic information, which can usually be found on a recent energy bill:
- Your postcode.
- The name of your current supplier(s) and tariff(s).
- Your annual energy consumption in kilowatt-hours (kWh). If you don’t have this, providers can estimate it based on your household size.
Comparison websites such as UKPower and Confused.com use your postcode to instantly show you the dual fuel deals available in your area, making the initial search straightforward.
Switching Suppliers: A Step-by-Step Guide
The process of switching to a new dual fuel provider is simpler than many expect and is handled almost entirely by your new supplier.
- Gather Your Information: Find a recent energy bill containing your usage and current tariff details.
- Use a Comparison Site: Visit a trusted comparison platform like Uswitch, CompareTheMarket, or MoneySavingExpert.
- Enter Your Details: Input your postcode and energy consumption data.
- Compare Your Options: Review the list of dual fuel tariffs. Filter by price, customer service rating, or green credentials.
- Select Your New Tariff: Choose the deal that best suits your needs and budget.
- Complete the Application: Fill in your details to begin the switch. This usually takes just a few minutes.
- Let Your New Supplier Handle It: Your new provider will contact your old one and manage the entire transition. There will be no interruption to your supply.
- Provide Meter Readings: You will be asked for a final reading for your old supplier and an opening reading for your new one.
Dual Fuel: The Pros and Cons
Before making a decision, it is wise to weigh the advantages and disadvantages of a dual fuel tariff.
| Pros | Cons |
|---|---|
| Simplified Billing: One bill, one payment, and one supplier to contact. | Not Always Cheaper: Separate gas and electricity deals can sometimes be more cost-effective. |
| Potential Discounts: Many suppliers offer an annual discount for bundling services. | Exit Fees: Leaving a fixed-term contract early can incur a penalty. |
| Convenience: Easier account management and less administrative hassle. | Complacency Risk: It’s easy to remain on a poor-value tariff after the initial fixed term ends. |
Key Considerations Before You Commit
Look beyond the headline price. A tariff that appears cheap initially might have drawbacks.
- Customer Service: A low price is less appealing if the supplier is difficult to contact. Providers like Octopus Energy and 100Green have built strong reputations based on customer satisfaction.
- Exit Fees: Check the penalty for leaving a fixed-term contract early. This is a crucial factor if your circumstances might change.
- Contract Length: Ensure the fixed-term length aligns with your plans. Once it ends, you will likely be moved to a more expensive standard variable tariff, so be ready to switch again.
Exploring Alternatives to Dual Fuel
While dual fuel is a convenient option, it is not the only one.
- Separate Suppliers: The most diligent consumers may find that sourcing gas and electricity from two different providers yields the lowest overall cost. This requires more management but can maximise savings.
- Green Tariffs: If environmental impact is your priority, you can choose a supplier that provides 100% renewable electricity. Many providers, including dual fuel suppliers, offer green options.
- Bundled Home Services: Companies like Utility Warehouse offer energy as part of a wider package including broadband, mobile, and insurance. While recognised by Which? as a Recommended Provider, it is important to cost each service individually to ensure the bundle offers true value.
