What is an energy tariff in Ireland?

An energy tariff sets the price you pay for electricity and gas, combining a unit rate for what you use with a standing charge for being connected. In Ireland you can choose fixed tariffs that lock the rate for a period, standard variable tariffs, and specialist options such as prepay meters, smart time-of-use plans and green tariffs. Switching supplier is straightforward and is the main way to cut energy bills.

How the Irish market works

The retail energy market is fully deregulated, with ESB Networks and Gas Networks Ireland owning the wires and pipes while competing suppliers sell tariffs. Electric Ireland, Bord Gáis Energy, SSE Airtricity, Energia, Pinergy, PrepayPower, Yuno Energy and others compete for customers, often with first-year discounts for switching. The Commission for Regulation of Utilities regulates the market, and smart meters are being rolled out nationwide to enable time-of-use pricing.

Benefits

Switching discounts — new-customer sign-up discounts can significantly cut your first-year bill.

Fixed-price certainty — fixed tariffs protect you from wholesale price rises for the contract term.

Smart time-of-use — smart-meter tariffs reward shifting usage to cheaper off-peak periods.

Green options — renewable tariffs let you buy electricity backed by green generation.

How to choose

Compare the estimated annual bill for your usage rather than the headline discount, since standing charges and unit rates both matter. Check the contract length and what the price reverts to after any discount period, note exit fees on fixed contracts, and consider a smart tariff if your usage is flexible. Dual-fuel deals bundle gas and electricity, and prepay suits those who prefer to pay as they go.

Leading providers in Ireland

Electric Ireland is the largest supplier, with Bord Gáis Energy, SSE Airtricity and Energia among the main competitors across electricity and gas. Pinergy focuses on smart and flexible plans, PrepayPower leads the prepay market, and newer entrants such as Yuno Energy, Power Direct and Glow Power compete aggressively on price for switchers.

What it costs

Costs depend on usage, tariff and standing charges, with monthly figures in this market broadly ranging from around €135 to €250 for typical households, before switching discounts. The single biggest saving lever is switching supplier at the end of a discount period, since loyal customers often roll onto higher standard rates. Compare estimated annual bills for your own consumption to see the real cost.

Protections and regulation

The Commission for Regulation of Utilities regulates energy suppliers, setting rules on billing, switching, disconnection safeguards and vulnerable-customer protections. Suppliers must provide clear tariff information and honour the cooling-off period after switching. The CRU also oversees the smart-meter programme, and the Commission for Regulation of Utilities operates a complaints process alongside supplier-level resolution.

Common questions

How do I save on energy? — Switch supplier when your discount period ends rather than rolling onto the standard rate.

Are exit fees charged? — Fixed-term contracts may charge an exit fee for leaving early, so check before signing.

What is a smart tariff? — A smart-meter plan with time-of-use pricing that rewards shifting usage to cheaper off-peak hours.
