Heat pump cost in Ireland
Heat pumps are now one of the biggest home-energy upgrades Irish homeowners consider, especially when replacing oil, gas or older electric heating. The main challenge is that the quote is not just the heat pump unit: it may include design, hot-water cylinder changes, radiator upgrades, controls, electrical work and insulation improvements.
For a typical Irish three-bedroom home, air-to-water heat pump installations are often quoted around €12,000 to €18,000 before grants, while ground or water-source systems can cost more. In 2026, SEAI heat pump supports can be worth up to €12,500 depending on dwelling type and eligibility, so checking the grant route before signing a contract is essential.

SEAI grant checks
SEAI lists heat pump grants as a bundle that can include support for the heat pump system, central-heating upgrade works and a renewable heat bonus when replacing fossil-fuel heating. Grant values and eligibility can change, so homeowners should check the current SEAI rules before ordering equipment.
When a heat pump works best
- The home is well insulated and draughts are controlled.
- Radiators or underfloor heating can deliver enough heat at lower flow temperatures.
- The system is sized from a proper heat-loss assessment.
- Controls and hot-water storage are planned for the household's real usage.
- The installer explains expected running costs, not just installation cost.
What to ask installers
Ask whether the quote includes the technical assessment, heat-loss calculation, cylinder, controls, electrical work, commissioning, grant paperwork and any radiator changes. A heat pump can be a strong upgrade, but only when the whole heating system is designed properly.
