What Is a Dual Fuel Offer?
A dual fuel offer bundles your electricity and natural gas supply with one provider under a single contract. Instead of managing two separate accounts, you receive one combined bill and often benefit from a larger discount than you would get by signing up for electricity or gas individually.
In Ireland, dual fuel is only available to households connected to the natural gas network, which primarily covers urban and suburban areas. Rural homes relying on oil, LPG, or solid fuels cannot avail of dual fuel deals.
Most major Irish energy suppliers offer dual fuel packages, including Energia, Bord Gais Energy, SSE Airtricity, Electric Ireland, Yuno Energy, and Flogas.
Advantages and Disadvantages of Dual Fuel
Bundling your energy supply with one provider has clear benefits, but it is not always the cheapest option. Here is what to consider:
Advantages
- Bigger discounts: Suppliers reserve their deepest discounts for dual fuel customers, often 5–10% more than electricity-only deals.
- Single bill convenience: One account, one direct debit, one customer service number for all your energy needs.
- Easier switching: Move both fuels at once instead of managing two separate contracts.
- Cashback bonuses: Many dual fuel sign-up offers include higher cashback than standalone plans.
Disadvantages
- Not always cheapest: The cheapest electricity-only and gas-only plans from different providers may beat a dual fuel bundle.
- Less flexibility: You are locked to one supplier for both fuels during your contract.
- Limited availability: Only homes with a gas connection can avail of dual fuel deals.
- Discount expiry: Welcome discounts typically end after 12 months, reverting to higher standard rates.

In most cases, yes. As of May 2026, the cheapest dual fuel deal is approximately €67 cheaper per year than combining the cheapest standalone electricity and gas plans separately. However, this gap varies by supplier and the specific discounts available at any given time. Always compare the total annual bill rather than individual discount percentages.
Switching to a dual fuel offer works the same way as switching any energy plan. You will need your MPRN (electricity) and GPRN (gas) numbers from your bills, plus your annual usage figures. The new supplier handles the entire process, which typically takes 10–14 working days. You are protected by a 14-day cooling-off period. Read our full switching guide for step-by-step instructions.
