Energy bills are a major household expense, and choosing the right tariff can make a significant difference to your costs. Dual fuel tariffs, where both gas and electricity are supplied by the same provider, offer convenience and potential savings. But is it always the best option? In this guide, we explore the benefits, potential drawbacks, and whether a dual fuel plan is right for your home.
What is a Dual Fuel Energy Tariff?
A dual fuel tariff is an energy plan where a single supplier provides both gas and electricity to a household. Instead of dealing with two separate energy providers, customers receive one bill and one point of contact for both utilities.
Key Features of a Dual Fuel Tariff:
One supplier for both gas and electricity
A single monthly bill instead of separate payments
Often includes discounts or lower rates for bundling services
Easier account management with one provider
Benefits of a Dual Fuel Tariff
1. Cost Savings and Discounts
Many energy suppliers offer discounts for customers who sign up for a dual fuel tariff. These discounts vary by provider but can result in lower overall costs compared to purchasing gas and electricity separately.
Additionally, suppliers may offer loyalty rewards, cashback, or special promotions for dual fuel customers.
2. Convenience and Simplicity
Managing energy accounts can be complicated, especially when dealing with two different suppliers. With a dual fuel tariff:
You have one bill for both gas and electricity
You only need to deal with one provider for customer service and billing issues
Meter readings and payments are streamlined
3. Easier Switching Process
If you decide to switch energy providers in the future, having both services with one company makes the process simpler. Instead of negotiating separate contracts, you only have to compare dual fuel tariffs and transfer everything at once.
4. Fixed and Variable Rate Options
Dual fuel tariffs come in both fixed-rate and variable-rate options, allowing customers to choose the level of price stability they prefer:
Fixed Dual Fuel Tariff: Your unit rates remain the same for a set period (e.g., 12, 24, or 36 months).
Variable Dual Fuel Tariff: Prices fluctuate based on market conditions, meaning your bills can go up or down.
5. Potential for Green Energy Plans
Many energy providers now offer dual fuel tariffs with renewable energy sources, allowing customers to power their homes with 100% green electricity and offset gas emissions with carbon-neutral schemes.
Are There Any Drawbacks to Dual Fuel Tariffs?
While dual fuel tariffs offer many advantages, they are not always the cheapest option for every household.
1. Not Always the Cheapest Deal
Although discounts are available, separate gas and electricity tariffs from different suppliers may sometimes work out cheaper. It’s always worth comparing dual fuel and individual tariffs before committing.
2. Limited Supplier Choice
Some smaller energy companies only supply gas or electricity, meaning dual fuel customers may miss out on competitive rates from niche providers.
3. Exit Fees on Fixed Contracts
If you sign up for a fixed dual fuel tariff, you may be charged an exit fee if you decide to switch before the contract ends. Check the terms before signing up.
Who Should Consider a Dual Fuel Tariff?
A dual fuel tariff is ideal if you:
Prefer the convenience of one bill and one provider.
Want to simplify your account management.
Are happy to accept a modest discount in exchange for bundling gas and electricity.
Value an easier switching process when changing suppliers.
However, if getting the absolute lowest price is your priority, it may be worth comparing separate gas and electricity deals to see if switching suppliers individually saves more money.
How to Find the Best Dual Fuel Deal
To get the best dual fuel tariff, follow these steps:
Compare Tariffs Online: Use an energy comparison website to check whether dual fuel is cheaper than separate tariffs.
Check Supplier Discounts: Look for providers offering sign-up bonuses or loyalty rewards.
Choose Fixed or Variable: Decide whether you prefer a fixed tariff for stability or a variable tariff for flexibility.
Look for Green Energy Options: If sustainability is important, check if the supplier offers renewable energy sources.
Read the Terms and Conditions: Check for exit fees, contract lengths, and any hidden charges.

Final Thoughts
A dual fuel energy tariff can be a convenient way to simplify household bills and potentially save money. However, it’s not always the cheapest option, so it’s essential to compare tariffs before making a decision.
If you value simplicity, a single bill, and supplier discounts, dual fuel could be a great choice. But if you’re focused solely on getting the lowest energy prices, it may be worth shopping around for separate gas and electricity deals.
