Dual Fuel Considerations
If you use both electricity and gas, bundling with one supplier can simplify billing and may offer small additional discounts.
Reasons to Bundle
- Single bill
- Single customer service contact
- Potential bundle discount (typically €50-€100/year)
- Simpler account management
Reasons Not to Bundle
- Best electricity deal may be with a different supplier than best gas deal
- Separately switching each fuel may yield greater savings
- More flexibility to switch one fuel if needed
For many households, the convenience of dual fuel outweighs the potential savings from optimising each fuel separately.
Microgeneration and Solar
Both suppliers offer export payments for customers with solar panels or other microgeneration.
Electric Ireland Export Rates
Customers with microgeneration can receive payment for exported electricity. Rates vary—check current offerings.
Bord Gáis Export Rates

Which Supplier Is Better?
There's no universal answer. The "better" supplier depends on:
Choose Electric Ireland If:
- Their current promotional offer is better
- You prefer dealing with a state-owned company
- You're already an Electric Ireland customer and they've offered a competitive retention deal
- Their smart meter tariff suits your usage pattern
Choose Bord Gáis Energy If:
- Their current promotional offer is better
- You want to bundle with their gas service
- You value their rewards programme
- Their smart meter tariff suits your usage pattern
The Real Answer
Switch based on current offers, not brand loyalty. The supplier with the best deal today may not have the best deal next year. Check comparison sites regularly and switch every 12 months for the best prices.
How to Switch Between Them
Switching from Electric Ireland to Bord Gáis (or vice versa) follows the standard switching process:
- Compare current offers using a price comparison site
- Apply to the new supplier online
- Provide your MPRN (electricity) and/or GPRN (gas)
- Your new supplier handles the switch
- Continue using energy—no interruption
- Receive a final bill from your old supplier
- Start receiving bills from your new supplier
The switch typically takes about 21 days.
Summary
Electric Ireland and Bord Gáis Energy are closely matched competitors. On standard rates, prices are very similar. The difference comes from promotional offers, which change regularly.
Key takeaways:
- Compare current deals before switching—don't assume one is always cheaper
- Watch for annual price adjustment clauses
- Consider dual fuel for convenience, but calculate whether it's truly cheaper
- Switch every 12 months to access new customer deals
- Smart meter tariffs are available from both suppliers
