Both Energia and SSE Airtricity are strong alternatives to Electric Ireland, consistently offering some of the lowest unit rates in the Irish market. But which one is the better choice for your home in 2026?
This comparison covers unit rates, standing charges, green energy options, discounts, and switching experience — so you can make an informed decision.
Quick Summary
| | Energia | SSE Airtricity | |---|---|---| | Electricity unit rate (from) | ~28.1c/kWh | ~28.3c/kWh | | Standing charge (from) | ~72.6c/day | ~66.3c/day | | Green tariff available | ✅ Yes | ✅ Yes | | Gas supply | ✅ Yes | ✅ Yes | | Smart meter tariffs | ✅ Yes | ✅ Yes | | Cashback/welcome offers | Varies | Varies |
Both suppliers are competitive. SSE Airtricity often has a slightly lower standing charge, while Energia can edge ahead on unit rate for certain tariff types.
Unit Rate Comparison
Unit rate is the per-kWh cost of the electricity you actually use. It's the biggest driver of your bill if your usage is high.
Energia offers rates from around 28.1c/kWh on their best electricity tariff. Their EV and smart meter tariffs can push this lower for off-peak usage.
SSE Airtricity offers rates from around 28.3c/kWh. Their green tariffs are competitively priced and the company has historically been one of the cheapest electricity providers in Ireland.
Verdict: Roughly equal — Energia has a marginal edge on unit rate for standard plans.
Standing Charge Comparison
The standing charge is a fixed daily cost regardless of how much electricity you use. If your household uses a lot of electricity, this matters less. For low-usage homes, it can make a significant difference.
- Energia: ~72–76c/day depending on tariff
- SSE Airtricity: ~66–70c/day depending on tariff
Verdict: SSE Airtricity tends to have a lower standing charge, making it better for low-usage households.
Green Energy Options
Both suppliers offer green electricity tariffs certified under the Guarantees of Origin (GO) scheme.
Energia Green: Includes Guarantees of Origin. Energia has invested in wind generation in Ireland and the UK. Their green tariff is straightforward with no premium pricing vs competitors.
SSE Airtricity Green: SSE has long positioned itself around renewable energy and owns wind and solar assets in Ireland. Their green tariff is well-established.
Verdict: Both are credible green options. SSE Airtricity has a longer heritage in Irish renewables.
Discount Structures
Both suppliers offer percentage discounts on their standard rates for new customers. Discounts typically apply for 12 months and are applied to your bill (not just the first bill).
- Watch for discounts on both electricity and gas when taking dual fuel from either supplier
- Online account management usually required to qualify
- Direct debit typically required
Always compare the post-discount rate — a higher headline rate with a bigger discount can end up cheaper than a lower rate with a smaller discount.
Smart Meter & EV Tariffs
Both suppliers offer tariffs that take advantage of your smart meter's half-hourly data.
Energia Smart: Time-of-use tariff with a cheaper overnight rate (typically 11pm–8am). Good for EV owners or households that can shift usage to night hours.
SSE Airtricity Smart: Also offers time-of-use rates. The night rate window and pricing varies — check the current rate on their website or compare on GoSwitch.
If you have an EV or storage battery, a smart meter time-of-use tariff from either supplier could cut your charging costs significantly.
Gas Supply
Both Energia and SSE Airtricity supply natural gas in Ireland, making them dual-fuel options.
Taking both electricity and gas from the same supplier usually comes with a dual-fuel discount (typically 5–10% off one or both fuels). Whether this is worth it depends on the headline rates — sometimes two separate suppliers still work out cheaper.
Use GoSwitch to compare dual-fuel vs separate plans for your specific usage.
Customer Service & Switching Experience
Both suppliers are regulated by the Commission for Regulation of Utilities (CRU) and must follow the same switching rules:
- Switches complete within 5–7 working days
- No supply interruption during the switch
- Right to cancel within 14 days of signing up
Energia has a modern online portal and app. Customer service reviews are generally positive for billing and account management.
SSE Airtricity is a larger operation with a more established support infrastructure. Response times can vary but overall feedback is comparable.
Which Should You Choose?
| Scenario | Best Choice | |---|---| | Low electricity usage | SSE Airtricity (lower standing charge) | | High electricity usage | Energia (marginally lower unit rate) | | Green energy priority | Either — both credible | | EV / night rate | Compare both smart tariffs on GoSwitch | | Dual fuel | Run the numbers — dual-fuel discounts vary |
The difference between the two is often less than €20/year for a typical household. The best approach is to compare live rates using GoSwitch, since pricing changes regularly.
