Best Electricity Tariff for Heat Pumps in Ireland (2026)

Heat pumps rely entirely on electricity, which means your tariff plays a major role in annual heating costs. Even small differences in unit rate can significantly affect your overall bill. Choosing the right electricity plan is essential for protecting long-term savings.

Quick answer: what is usually best for heat pump homes?

For most households with a heat pump, a competitive unit rate and reasonable standing charge are the most important factors. Some homes may benefit from time-based pricing, but only if heating demand can align with cheaper periods.

Why electricity rates matter more with a heat pump

Unlike oil or gas systems, a heat pump increases your electricity usage throughout the year, particularly in winter. Because heating demand can represent a large portion of total consumption, the electricity unit rate has a direct impact on annual costs.

Should you choose a smart tariff for a heat pump?

Some smart tariffs offer cheaper electricity during certain hours of the day. If your heating system can operate more during lower-cost periods, a time-based plan may reduce costs. However, many smart plans also include higher peak pricing.

Before switching to a smart tariff, read: Smart Tariffs Ireland (2026).

When a flat-rate plan may be better

Your heating demand is spread evenly throughout the day.
You cannot reliably shift heating into cheaper time bands.
The smart plan has a high peak rate that offsets off-peak savings.

In these cases, a competitive flat-rate plan may be more suitable. See: Cheapest Electricity in Ireland (2026).

Estimate the impact of tariff changes

If your heat pump uses 5,000 kWh per year and your unit rate drops by 0.05 per kWh, that could reduce annual heating costs by around 250. This illustrates why comparing electricity plans is important for heat pump households.
