SSE Airtricity is one of Ireland's three largest electricity suppliers — a household name with over two decades in the Irish market. Pinergy is a specialist smart PAYG supplier that has built a loyal following among budget-conscious and tech-engaged households. They serve different needs, but both compete for Irish electricity customers. Here's how they compare in 2026.
Quick Summary
| | Pinergy | SSE Airtricity | |---|---|---| | Electricity supply | Yes | Yes | | Gas supply | No | Yes | | Pay as you go | Yes — core product | No | | Smart meter tariff | Yes | Yes | | Night-rate tariff | Yes | Yes | | Green electricity | Yes (Pinergy Pure) | Yes | | New customer discount | Yes | Yes (up to 35%) | | Large supplier | No | Yes |
About SSE Airtricity
SSE Airtricity is part of the SSE Group and is one of Ireland's dominant electricity suppliers. They offer electricity and gas, a dual fuel bundle, and competitive new customer discounts — typically 30–35% off the standard unit rate for the first 12 months.
SSE Airtricity is also one of Ireland's leading renewable energy developers, with a large portfolio of wind farms. Their electricity supply includes green electricity options for customers who want verified renewable energy.
SSE Airtricity standard electricity:
- New customer discounts: typically 30–35% off unit rate for 12 months
- Standard unit rates (pre-discount): in line with the market average
- Standing charges: broadly in the market average range
- Smart meter night-rate tariff available
About Pinergy
Pinergy pioneered smart prepay electricity in Ireland and has built its product around real-time visibility and control. Unlike all other Irish suppliers, Pinergy's core product is PAYG — you top up in advance via their app, and usage is deducted in real time. This eliminates estimated bills, billing disputes, and the risk of unexpected large quarterly charges.
Pinergy also offers:
- Pinergy Pure — 100% renewable electricity
- Night Boost — discounted overnight rate for smart meter customers
- EV tariff — optimised for electric vehicle home charging
- Standard credit billing for customers who prefer it
Electricity Tariff Comparison
Standard Credit Tariff
On standard credit tariffs, SSE Airtricity's new customer discount of 30–35% makes them highly competitive in the first year. After 12 months, the rate reverts to their standard tariff — at which point switching again is strongly advisable.
Pinergy's credit tariff rates are competitive, though the headline unit rate comparison is slightly complicated by Pinergy's PAYG-first structure. On a like-for-like credit basis, Pinergy and SSE Airtricity are broadly comparable in price — the gap shifts with each round of supplier pricing updates.

New Customer Discount
SSE Airtricity's promotional discounts (30–35%) are among the largest available in the Irish market. For households who switch regularly and prioritise maximising the first-year saving, SSE Airtricity often ranks at or near the cheapest end of the market during the discount period.
Pinergy offers new customer discounts as well, though their PAYG product means the discount structure works differently.
PAYG vs Credit: The Key Difference
This is the most significant practical distinction between the two suppliers:
| | Pinergy | SSE Airtricity | |---|---|---| | PAYG option | Yes — primary product | No | | Real-time top-up | Yes (Pinergy app) | No | | Bill shock risk | Zero — prepaid | Standard (post-usage billing) | | Debt risk | Zero — no credit | Standard direct debit | | Budget control | Maximum | Standard |
For households where PAYG is the reason to choose Pinergy — renters wanting control over energy spend, households managing tight budgets, landlords who want tenant billing simplicity — SSE Airtricity cannot replicate this. It's a structural difference, not just a tariff difference.
Smart Meter Tariffs
Both suppliers offer night-rate plans for smart meter customers:
SSE Airtricity — discounted overnight rate for smart meter customers, suitable for EV charging and overnight appliance use.
Pinergy Night Boost — similar overnight discounted rate, with the added advantage of real-time app visibility showing exactly what you're spending per hour.
For EV owners, both suppliers are solid choices on night rate. Pinergy's app-based real-time visibility gives it an edge in actively managing charging costs.
Green Electricity
Both offer green electricity:
- SSE Airtricity — renewable electricity options backed by their own Irish wind portfolio
- Pinergy Pure — 100% renewable electricity at a competitive price
Neither has a strong advantage here — both provide verified green electricity.
Gas Supply
SSE Airtricity supplies both electricity and gas, and offers a dual fuel bundle with a combined discount for taking both.
Pinergy is electricity-only. Gas customers will need a separate supplier.
If dual fuel simplicity (one bill, one direct debit) matters, SSE Airtricity has the advantage.
Customer Service and Brand
SSE Airtricity, as one of Ireland's largest suppliers, has an established customer service operation. Their scale means more call centre capacity, though reviews on billing dispute resolution are mixed — as with all large Irish suppliers.
Pinergy's smaller scale often translates to more responsive customer service, particularly for technical issues with the PAYG system.
Who Should Choose Which?
Choose Pinergy if:
- PAYG/prepay electricity suits your household (renters, tight budgets, landlords)
- You want real-time usage visibility via app
- You want 100% renewable electricity (Pinergy Pure)
- You're an EV owner who wants granular visibility of overnight charging costs
Choose SSE Airtricity if:
- Maximising the first-year new customer discount (30–35%) is the priority
- You also use gas and want a dual fuel bundle from one supplier
- You prefer conventional credit billing with no top-up management
- Green electricity from an Irish wind portfolio matters to you
Verdict
SSE Airtricity wins on new customer discount size and dual fuel capability. Pinergy wins on PAYG flexibility, real-time app visibility, and for households where eliminating bill surprise is a priority. On pure electricity price for standard credit billing, the two are closely matched — run the comparison on GoSwitch for the current live rates.
