Best Dual Fuel Deals in Ireland (2026) - Gas and Electricity Bundles
Dual fuel deals combine your gas and electricity supply with one provider. In some cases, bundling both services can reduce overall energy costs. However, the best option depends on unit rates, standing charges, and how discounts are applied.
What is a dual fuel deal?
A dual fuel plan means you receive both your gas and electricity from the same supplier. Providers may offer bundle discounts for customers who switch both services together.
Dual fuel can simplify billing, but it is important to compare the full price structure rather than focusing only on headline discounts.
Are dual fuel deals cheaper in Ireland?
Dual fuel deals can be cheaper in some cases, particularly where gas discounts are stronger when bundled with electricity. The best value depends on:
- Electricity unit rate and standing charge
- Gas unit rate and standing charge
- Discount structure and duration
- Your annual usage pattern
Always compare the total annual cost rather than just the percentage discount.
When dual fuel may make sense
- You want one supplier and one bill.
- The bundle discount is meaningful compared to standalone plans.
- Your electricity tariff type suits how you use electricity.
When separate suppliers may be better
- The cheapest electricity supplier is not the cheapest gas supplier.
- You benefit from a specific electricity tariff type, such as smart or day and night.
- A bundle discount hides higher underlying unit rates or higher standing charges.
Compare gas and electricity separately
Before choosing a dual fuel bundle, it can be useful to compare standalone pricing:
In some cases, separate suppliers may offer lower combined annual costs.
Dual fuel and smart tariffs
If you have an electric vehicle, solar panels or a heat pump, you may want to review electricity tariff options carefully, even if considering a gas bundle.
