What is a dual fuel deal?

Defining dual fuel

A dual fuel deal means you receive both your gas and electricity from the same energy supplier. This arrangement is a popular choice among households seeking convenience and clarity in their energy supply.

How dual fuel works

When you opt for a dual fuel deal, your chosen supplier becomes responsible for providing both your gas and electricity. While many dual fuel deals typically result in a single monthly bill covering both services, some suppliers, like Fuse Energy, provide separate bills for each fuel even when you get both from them. In either case, you will interact with one customer service team for any queries or issues. Many energy suppliers offer incentives or discounts for customers who choose dual fuel tariffs, aiming to attract and retain customers by simplifying their energy experience.

The benefits of choosing dual fuel

Simplified billing and administration

One of the most immediate advantages of a dual fuel deal is the simplification of your household finances. While some dual fuel deals offer one consolidated statement, even with separate bills from a single supplier, you avoid managing accounts with different companies. This makes budgeting easier and reduces the administrative burden of keeping track of multiple accounts.

Potential cost savings

While not always guaranteed to be the cheapest option, dual fuel deals often come with potential cost savings. Many suppliers offer discounts or a slightly lower overall rate when you commit to getting both your gas and electricity from them. It is always worth comparing these bundled offers against separate tariffs to ensure you are getting the best value for your specific energy usage.

Streamlined customer service

Dealing with a single supplier for both gas and electricity means a single point of contact for all your energy-related queries. Whether you have a question about your bill, need to submit a meter reading, or require support, you will only need to contact one company. This can lead to a more efficient and less frustrating customer service experience. Some modern dual fuel deals, such as those from Fuse Energy, also offer 24/7 human support, providing peace of mind that help is available whenever you need it.

How to compare dual fuel deals effectively

Finding the best dual fuel deal requires a bit of homework, but the effort can lead to significant savings and greater peace of mind.

Understanding your energy usage

The first step in comparing dual fuel deals is to understand your own energy consumption. Your recent energy bills will show your annual gas and electricity usage in kilowatt-hours (kWh). The average UK home uses approximately 2,500 kWh of electricity per year. Knowing your usage patterns is crucial because tariffs are structured around how much energy you consume, influencing your overall annual cost.

Key factors to compare (rates, standing charges, exit fees)

When comparing dual fuel tariffs, look beyond just the headline price. Consider these key factors:

  • Unit rates: This is the cost per kWh of gas and electricity you use.
  • Standing charges: A fixed daily charge that applies regardless of how much energy you consume.
  • Exit fees: Some fixed-term contracts include a fee if you switch suppliers before the contract ends. Variable tariffs typically do not have these.
  • Fixed vs variable rates: Fixed tariffs lock in your unit rates for a set period, offering predictability. Variable tariffs can change with the market.

Is dual fuel always cheaper than separate suppliers?

No, dual fuel is not always cheaper. While many suppliers offer discounts for bundling, it is essential to compare dual fuel deals against the combined cost of getting gas and electricity from two separate, potentially cheaper, suppliers. Your specific usage and available tariffs will determine the best value.

Using comparison websites

Reputable comparison websites are invaluable tools for exploring available dual fuel tariffs. These platforms allow you to input your energy usage and postcode to generate a personalised list of deals. They help you compare unit rates, standing charges, and estimated annual costs from various suppliers, making it easier to find a competitive option.

Looking beyond price: service and support

While price is a major factor, it should not be the only one. Consider the supplier's customer service quality, their digital tools (like apps for managing your account and tracking usage), and their overall reputation. Poor customer service can lead to frustration, even if the tariff is cheap. Ofgem regulates the energy market in Great Britain, ensuring fair practices for consumers and setting standards for suppliers.

Making the switch to a new dual fuel deal

Switching energy suppliers is a straightforward process, designed to be hassle-free for consumers.

Step-by-step switching process

  1. Gather information: Have your current energy bills handy to provide accurate usage data.
  2. Compare deals: Use a comparison website or directly check supplier tariffs to find a suitable dual fuel deal.
  3. Choose a supplier: Select the deal that best meets your needs for price, terms, and service.
  4. Initiate the switch: Your new supplier will handle most of the switching process. You will typically need to provide your address, current supplier details, and a recent meter reading.
  5. Final meter readings: You may be asked to provide a final meter reading to your old and new suppliers to ensure a smooth transition and accurate final bill.
  6. Confirmation: The switching process is designed to be completed within 5 working days under Ofgem's Faster Switching rules. Your new supplier will confirm your switch date and provide all necessary details.

What to expect after switching

Once your switch is complete, you will begin receiving bills from your new dual fuel supplier. Your old supplier will send a final bill. If you had credit with your previous supplier, this does not automatically transfer; you will need to contact them directly for a refund to your bank account. It is a good idea to monitor your first few bills from the new supplier to ensure everything is accurate.

Common switching questions

  • Will my energy supply be interrupted? No, your energy supply will not be interrupted during the switch. It is a seamless administrative process.
  • Can I change my mind? You have a 14-day cooling-off period after agreeing to a new contract, during which you can cancel without penalty.
  • What if something goes wrong? Ofgem oversees the energy market, and you have consumer rights if you encounter issues during or after a switch.
