Heat Pump Cost Ireland
Heat pump cost in Ireland ranges from €3,000 for a basic air-to-air unit to €30,000 for a ground-source system with borehole drilling. Air-to-water, the most common choice, typically runs €9,000 to €18,000 installed before the SEAI grant.
Installed Cost by Heat Pump Type
Gross cost varies most by system type. Net cost after the SEAI grant closes much of that gap for air-to-water and ground-source systems.
| System type | Installed cost, before grant | Typical net cost | Best suited to |
|---|---|---|---|
| Air-to-water | €9,000–€18,000 | €1,500–€5,500 | Most Irish homes with radiators or underfloor heating |
| Ground-source | €15,000–€30,000 | €2,500–€17,500 | Larger rural properties with garden space for loops or a borehole |
| Air-to-air | €3,000–€8,000 | Often near €0–€4,500 | Supplementary heating, doesn’t heat water |
Ranges reflect current market quotes and vary by installer, home size, and site conditions. An SEAI-registered installer confirms an exact price during survey.
What Moves the Price Up or Down
Net Cost After the SEAI Grant
Subtracting the maximum €12,500 grant from a typical €9,000 to €18,000 air-to-water installation brings most homes to roughly €1,500 to €5,500 out of pocket. Ground-source starts from a higher base, so net cost after the same maximum grant runs wider, roughly €2,500 to €17,500.
Not all of the grant lands at once. The €6,500 unit and €2,000 heating-upgrade portions apply against the installation invoice, but the €4,000 renewable heat bonus is paid after 12 months of verified operation, not upfront. Budget for that gap.
Additional costs to budget for: a post-works BER assessment, typically €150 to €350, required to close out the grant claim. The separate €200 technical assessment grant offsets part of this.

Heat Pump Cost Questions
What’s the cheapest way to heat a home with a heat pump?
Air-to-air costs least upfront, from around €3,000, but it doesn’t heat water and suits supplementary heating rather than a whole-home system.
Why is ground source so much more expensive?
Borehole drilling or trenching for the ground loop typically adds €4,000 to €10,000 over an equivalent air-to-water system.
Does the quote include VAT?
It should. Heat pump installation carries 9% VAT, reduced from 23% on 1 January 2025. Confirm this is reflected in any quote received.
Is the grant paid to me or the installer?
Process varies by route. Under a One Stop Shop, the provider deducts the grant upfront and the homeowner pays only the balance. Applying individually, the sequence and payment timing follow SEAI’s own process.
