Q: How do I switch to Power NI?

Switching to Power NI takes about five working days under the new Faster Switching service, and your supply is never interrupted. Sign up online with your address, postcode and a recent meter reading. Power NI will arrange the transfer with your current supplier, including the final meter reading and the closing bill.

Q: Are there exit fees on Power NI tariffs?

Most UK fixed-term tariffs include an exit fee (typically £25-£75 per fuel) if you switch before the contract ends. You can switch without an exit fee in the last 49 days of your contract. Variable tariffs (including the default tariff capped by the Energy Price Cap) have no exit fees.

Who is Power NI?

Registered as Power NI Energy Limited, Power NI uses this legal name for Ofgem licence filings, contracts and any formal communications. The trading name customers see on bills is the shorter, more recognisable form.

The company is headquartered in Belfast, where it runs its senior management, customer operations and regulatory liaison with Ofgem.

Power NI was established in 2011. A longer track record means more years operating under Ofgem rules and a wider history of customer feedback, billing systems and regulatory interactions.

Power NI is part of the Energia Group (formerly Viridian Group) group, which provides shared governance, financial backing and a broader pool of expertise in trading, hedging and regulatory work.

As a Northern Ireland energy supplier, Power NI is regulated by the Utility Regulator (UR) for Northern Ireland, not Ofgem. Statutory consumer protection is handled by the Consumer Council for Northern Ireland (CCNI), which escalates unresolved complaints on behalf of NI households.

Who owns Power NI?

Ownership: Privately owned
Listed: No
Parent: Energia Group (formerly Viridian Group)
Holders: Power NI is wholly owned by Energia Group, in turn owned by funds managed by I Squared Capital (a US-headquartered infrastructure investor). The transmission/distribution business — NIE Networks — was sold to ESB in 2011...

Current tariffs

Power NI tariffs: as of 14 May 2026

Northern Ireland electricity tariffs are not subject to the GB Energy Price Cap. Instead, every Power NI price change must be approved in advance by the Utility Regulator. There are no fixed-price plans on the Power NI book; every tariff is a variable rate. Discounts (online billing, direct debit) apply on top of the headline unit rate and pull the effective price down by 2.5% to 6%.

Power NI is an electricity-only supplier — it does not sell mains gas. If you also need a gas account in Northern Ireland, the supplier depends on your network: firmus energy covers the Ten Towns area and competes in Greater Belfast; SSE Airtricity Gas and Yuno Energy also compete in Greater Belfast.

Common questions

Power NI — frequently asked questions

Power NI is regulated by Ofgem and operates under a standard domestic-supply licence. Whether it is the right supplier for your household depends on your unit rate, standing charge, customer-service rating and any add-on services (HomeCare, Warm Home Discount eligibility). Always quote your annual kWh consumption when comparing prices — the headline rate alone does not predict your bill.

Switching to Power NI takes about five working days under the new Faster Switching service, and your supply is never interrupted. Sign up online with your address, postcode and a recent meter reading. Power NI will arrange the transfer with your current supplier, including the final meter reading and the closing bill.

The UK grid is supplied by a mix of gas, nuclear, wind, solar, biomass and imports. Power NI declares its fuel mix annually under Ofgem rules — see the fuel-mix section above for the current figures. Some tariffs are sold as 'green' or '100% renewable', which means the supplier matches your annual consumption with renewable electricity certificates (REGOs) rather than physically delivering renewable electrons to your home.

Most UK fixed-term tariffs include an exit fee (typically £25-£75 per fuel) if you switch before the contract ends. You can switch without an exit fee in the last 49 days of your contract. Variable tariffs (including the default tariff capped by the Energy Price Cap) have no exit fees.

You can reach Power NI on 08000 285 455, Mon-Fri 9 a.m. to 5 p.m. (free to call). For a full breakdown of phone lines (emergency, prepayment, HomeCare, bereavement, Welsh, Relay UK), see the Power NI contact page.
