What is the dual fuel plan for Bord Gáis?

Key features of Bord Gáis dual fuel

Combines electricity and gas under one supplier, with one bill (Bord Gáis Energy (official guide))
Smart All Day plan: 22% off electricity unit rate, 21% off gas unit rate (Bord Gáis Energy (campaign page))
5% discount after the first year if you stay on the plan (Bord Gáis Energy (guide))
Smart meter compatible (Bord Gáis Energy (guide))

Eligibility and contract terms

Available to residential customers with a gas and electricity connection (Bord Gáis Energy (guide))
12-month fixed term; early exit fee of €50 per fuel applies (Switcher.ie (supplier details))
Prices subject to change after the fixed term (Bord Gáis Energy (campaign page))

Bottom line: Bord Gáis dual fuel is a straightforward bundle with meaningful upfront discounts. For households that want simplicity and can commit to a year, it delivers real savings—but watch for exit fees if plans change.

The implication: Bord Gáis dual fuel offers clear upfront discounts but requires a 12-month commitment – factor that into your decision.

Who is the cheapest dual fuel provider in Ireland?

Four major providers dominate Ireland’s dual fuel market. The cheapest option depends on where you live, how much you use, and whether you qualify for discounts. Here’s how they stack up:

Provider	Electricity discount	Gas discount	Contract length	Exit fee
Bord Gáis Energy	22% (Smart All Day)	21% (Smart All Day)	12 months	€50 per fuel
Energia	Up to 20%	Up to 20%	12 or 24 months	Varies (check plan)
SSE Airtricity	10% dual fuel discount	10% dual fuel discount	12 months	€0 on some plans
Flogas	Competitive rates	Competitive rates	12 months	€50 per fuel

Source data: Switcher.ie (accredited comparison site) and Bonkers.ie (comparison platform).

Hidden fees and standing charges

All regulated suppliers charge a PSO levy (currently about €50 per year) (Bord Gáis Energy (campaign page))
Standing charges differ by provider and can add €100–€200 annually (Selectra (energy comparison))
Late payment fees and paper bill charges may apply; check the contract (CRU (regulator))

Bottom line: No single provider is cheapest for everyone. Use an accredited comparison tool like Switcher.ie or Bonkers.ie with your own usage to get a tailored quote. The headline discount isn’t the whole story—standing charges and exit fees matter just as much.

The pattern: The cheapest provider depends on individual usage, so always get a personalized quote before choosing.

Is dual fuel really worth it?

Upsides

One bill, one supplier – simpler management (Bord Gáis Energy (guide))
Average savings of €300–€500 per year (Bonkers.ie (comparison))
Bundled discounts typically higher than standalone offers (Switcher.ie (comparison page))

Downsides

Early exit fees (€50 per fuel) lock you in (Switcher.ie (supplier details))
Discounts can fall behind competitors after price hikes (The Irish Times)
Not ideal if you plan to switch frequently (CRU (regulator))

What this means: Bundling works well for stable households that value convenience. If you move or change usage patterns mid-contract, the exit fees can wipe out your savings. The trade-off is between flexibility and the upfront discount.

How do I switch to Bord Gáis dual fuel?

Step-by-step switching process

Compare dual fuel plans using an accredited site like Switcher.ie (comparison service).
Choose Bord Gáis dual fuel and complete the online sign-up—you’ll need your MPRN (electricity) and GPRN (gas) numbers, which appear on your current bills (Bord Gáis Energy (how to switch)).
Bord Gáis arranges the switch with your current supplier; supply is not interrupted (CRU (regulator)).
You have a 14-day cooling-off period after signing up (Bord Gáis Energy (how to switch)).
The switch completes in about 2 weeks (CRU (regulator)).

Documents and information needed

Current energy bills for MPRN/GPRN numbers
Your bank details for direct debit (required for best discount)
Email address for eBill (required for discount)

Cooling-off period and cancellation

14-day cooling-off period after signing the contract (Bord Gáis Energy (how to switch))
If you cancel within that period, no fees apply
After 14 days, the €50 per fuel exit fee applies until the end of the 12-month term (Switcher.ie (supplier details))

The catch

The 14-day cooling-off window is your only penalty-free escape. After that, you’re committed for a year—or €100 lighter.

Plan carefully: the cooling-off period is your only window to walk away without cost, so use it to double-check that the plan fits your usage.

How does Bord Gáis compare to other dual fuel providers?

Bord Gáis vs Energia

Energia offers similar discounts (up to 20% both fuels) but with green energy options (Switcher.ie (supplier listing))
Energia has a 24-month contract option, which may appeal to those wanting price certainty (Bonkers.ie (comparison))

Bord Gáis vs SSE Airtricity

SSE Airtricity offers a 10% dual fuel discount but includes 100% green electricity (Switcher.ie (supplier listing))
Some SSE plans have no exit fee, giving more flexibility (Bonkers.ie (comparison))

Bord Gáis vs Flogas

Flogas sometimes offers tariffs with no standing charge, which can be cheaper for low users (Switcher.ie (supplier listing))
Flogas discounts are less transparent; you need to get a personalised quote (Bonkers.ie (comparison))

The pattern: Bord Gáis leads on headline discounts, but competitors close the gap with green energy or lower exit fees. Your personal priorities—savings vs. flexibility vs. sustainability—should drive the choice.

What the experts say

“Dual fuel plans give you a single point of contact and one bill, which can make managing your energy much easier. The key is to compare the whole package—discount, standing charges, and exit fees—before signing up.”

— Bord Gáis Energy spokesperson, official dual fuel guide

“Switching suppliers is the fastest way to save on your energy bills. Use a comparison site to see what’s available in your area, and don’t assume your current provider is giving you the best deal.”

— Switcher.ie comparison expert, advice page

For Irish households, the choice is clear: compare all costs before you commit, because a headline discount can quickly be eroded by fees and price hikes. The cheapest plan today might not be cheapest in six months.

Frequently asked questions

Can I switch dual fuel providers if I am in a contract?

Yes, but you will likely have to pay an early exit fee (typically €50 per fuel). Some providers waive the fee if you switch within your cooling-off period or if the new provider offers to cover it (CRU (regulator)).

What happens at the end of a dual fuel fixed term?

You’ll be moved to a variable rate unless you actively switch or sign a new fixed-term plan. Variable rates are typically higher, so mark your calendar to recompare a few weeks before the term ends (Bord Gáis Energy (campaign page)).

Do I need a smart meter for dual fuel?

No, but smart meters are required for some time-of-use tariffs. Bord Gáis’ Smart All Day plan works with standard meters too (Bord Gáis Energy (guide)).

Is dual fuel available for prepay meters?

Most suppliers, including Bord Gáis, offer dual fuel for prepay meters, but discounts may be lower than for direct debit customers (Switcher.ie (supplier details)).

How do I cancel my dual fuel plan?

Contact your supplier in writing (email or letter). Bord Gáis requires 30 days’ notice. If you cancel within the 14-day cooling-off period, no fee applies (Bord Gáis Energy (how to switch)).

Does dual fuel cover both gas and electricity bills in one payment?

Yes—dual fuel means you receive a single bill for both fuels and make one payment. That’s the main convenience benefit (Bord Gáis Energy (guide)).
