What a Heat Pump Installer Does, and Why Registration Matters
Heat pump installers in Ireland fit air-to-water, ground source and air-to-air systems that replace an oil or gas boiler and heat your whole home from renewable energy. The one thing that matters most when choosing one is SEAI registration, because only a registered installer unlocks the heat pump grant of up to €12,500 (as of July 2026).
Every heat pump installer listed on hvacinireland.ie is drawn from the official SEAI register. Choosing an unregistered installer would forfeit the grant entirely, which is why registration is the first thing we check. From there you contact the installer directly, with no middleman and no lead-selling.
Signs It Is Time to Replace Your Boiler With a Heat Pump
The clearest sign it is time to replace your boiler with a heat pump is an oil or gas boiler that keeps breaking down or is already over ten to fifteen years old. A tired boiler is the natural moment to switch, because the SEAI grant of up to €12,500 (as of July 2026) brings a heat pump far closer to the price of a like-for-like boiler swap than most homeowners expect.
- Your oil or gas boiler is more than ten years old or needs frequent repairs
- Heating bills have climbed and you want lower, steadier running costs
- You are building or deep-retrofitting and can size the heating around a heat pump
- You have already upgraded attic and wall insulation, so the house holds its heat
- You want to move off fossil fuels before oil and gas prices rise again
If the boiler itself needs urgent attention before you decide, an RGI-registered plumber or gas installer at plumbersinireland.ie can advise on a repair or a straight swap while you weigh up the change.
Heat Pump Cost in Ireland, Before and After the Grant
Heat pump cost in Ireland depends on the system. Here is what each type runs, and what the SEAI grant brings it down to.
Air-to-water heat pump
€12,000 – €18,000
Net €1,500 – €11,500 (as of July 2026)
The standard choice for Irish homes. Heats radiators, underfloor and hot water.
Ground source heat pump
€20,000 – €30,000
Net €13,500 – €23,500
Higher efficiency from ground loops or boreholes. Best for larger rural sites.
Air-to-air heat pump
€3,000 – €8,000
Net from around €2,500
Lower-cost option that heats the air directly. Does not heat hot water.
How to Choose a Heat Pump Installer in Ireland
Choosing a heat pump installer in Ireland comes down to a few checks that protect both your home and your grant. Registration is the first, because only an SEAI-registered installer can unlock the grant, and the rest separate a good fit from a rushed one.
SEAI Registration
Confirm the installer is on the official SEAI register. It is a requirement for the grant, and every installer listed here already carries it.
A Proper Home Survey
A good installer surveys insulation, radiators and hot water before quoting, rather than pricing a system blind. The survey confirms your home is heat pump ready.
A Written, Itemised Quote
Ask for the heat pump, cylinder, radiator changes and controls listed separately, so you can see what the grant covers and what you pay.
References and Recent Work
Ask for recent installs in your county and a workmanship warranty. Local experience with Irish housing stock and radiators matters.
Clear Grant Handling
The installer should walk you through the SEAI application. The grant is only paid when a registered installer carries out the work, so the paperwork matters.
The Right Registered Trades
A heat pump needs a dedicated electrical supply and cylinder work. Check the installer works with a registered electrician for the connection.
Air Source vs Ground Source vs Air-to-Air Heat Pumps
Most Irish homes choose an air source heat pump, but ground source and air-to-air each suit particular homes. Here is how the three compare on cost, grant, efficiency and what they heat.
| Most common Air-to-Water | Ground Source | Air-to-Air | |
|---|---|---|---|
| Typical cost | €12,000 – €18,000 | €20,000 – €30,000 | €3,000 – €8,000 |
| SEAI grant | Up to €12,500 | Up to €12,500 | Up to €7,500 |
| Heats hot water | Yes | Yes | No |
| Efficiency | High | Highest | High for space heat |
| Best for | Most Irish homes | Larger rural sites | Smaller homes, single rooms |
For most Irish homes an air-to-water heat pump is the balance of cost, grant and whole-home heating. Ground source suits larger rural sites with space for ground loops, while air-to-air suits smaller homes or heating a single area.
Heat Pump Running Costs Compared to Oil and Gas
Heat pump running costs are lower than oil or gas for most Irish homes, because a heat pump delivers roughly three to four units of heat for every unit of electricity it uses. That efficiency, the coefficient of performance, is why a well-insulated home heated by a heat pump usually costs less to run than the boiler it replaced.
The exact saving depends on your insulation, your electricity tariff and what you are replacing. Homes on a day-and-night tariff can run the heat pump more cheaply overnight, and pairing it with solar panels offsets more of the electricity it draws.
- Roughly three to four units of heat per unit of electricity, well ahead of a boiler
- Lowest running costs come in a well-insulated, airtight home
- Night-rate electricity tariffs cut the cost of running the heat pump further
- Solar panels offset the electricity the heat pump uses across the year
Heat Pump Installation in Every County
Pick your county to see SEAI-registered heat pump installers covering your area.
The Heat Pump Grant Covers Up to €12,500 (as of July 2026)
The SEAI heat pump grant is one of the most valuable home energy grants in Ireland, covering a significant share of an air-to-water installation. To qualify, the installer must be registered with SEAI, and every heat pump installer listed here carries that registration.
Most homes qualify. If your house was built and occupied before 2021 and does not already have a heat pump, you are very likely eligible, and your installer confirms it during a free home survey before any work starts.
Insulation comes first. Good fabric makes a heat pump far more effective and cuts running costs, so most advisors recommend upgrading the house before installation. For SEAI-registered insulation contractors, wallinsulationireland.ie lists verified contractors across all 26 counties.
- Grant up to €12,500 for air-to-water heat pumps (as of July 2026)
- Homes built and lived in before 2021 usually qualify
- Every listed installer is SEAI-registered
From Choosing an Installer to Grant Payment in Four Steps
Heat pump installation follows the same path for most Irish homes. Knowing the four steps up front makes the SEAI grant process straightforward.
Choose an SEAI-Registered Installer
Pick a heat pump installer in your county from the listings. Every installer here is on the official SEAI register, which is a requirement for claiming the grant.
Book a Free Home Survey
The installer assesses your insulation, radiators and hot water needs. A BER rating of C or better is recommended, and the survey confirms whether your home is heat pump ready.
Apply for the SEAI Grant
You apply to SEAI for the heat pump grant of up to €12,500 (as of July 2026). The installer must be registered for the grant to be paid, and the application is made once the work is agreed.
Installation and Grant Payment
A typical air-to-water heat pump installation takes two to three days. SEAI pays the grant into your bank account, usually within six to eight weeks of a successful application.
Heat Pump Installation by County
SEAI-registered heat pump installers cover every county in Ireland, from Dublin and Cork to Galway, Mayo and Donegal. Pick your county to see who covers your area and how many installers are listed.
Heat Pump Installers in Ireland, Answered
How much does a heat pump cost in Ireland?
A typical air-to-water heat pump installation costs between €12,000 and €18,000 before grants. The SEAI grant of up to €12,500 (as of July 2026) brings the net cost to between €1,500 and €11,500, depending on what you are replacing and whether heating upgrades are needed. Ground source systems cost more but deliver higher efficiency.
Is my home suitable for a heat pump?
Most homes built after 2000 with reasonable insulation are suitable. Older homes may need insulation upgrades first, and a BER rating of C or better is recommended before installation. An SEAI-registered installer can carry out a free home survey to confirm suitability.
What SEAI grant is available for a heat pump?
SEAI offers a grant of up to €12,500 (as of July 2026) for an air-to-water heat pump and up to €7,500 for an air-to-air system. The installer must be SEAI-registered and you apply to SEAI after the installation is complete.
Are heat pumps cheaper to run than oil or gas?
For most well-insulated Irish homes, yes. A heat pump delivers roughly three to four units of heat for every unit of electricity it uses, so it typically costs less to run than the oil or gas boiler it replaces. The saving is largest in an airtight, well-insulated home and on a night-rate electricity tariff.
Do heat pumps work in cold Irish weather?
Yes. Air-to-water heat pumps are designed to extract heat from outdoor air well below freezing, and Ireland has a mild climate that suits them. A correctly sized system keeps a home warm through an Irish winter without a backup boiler.
Do I need new radiators for a heat pump?
Sometimes. A heat pump runs at a lower flow temperature than a boiler, so undersized radiators may need upsizing or a couple replaced. Underfloor heating is ideal but not required. The home survey identifies which radiators, if any, need attention.
How long does heat pump installation take?
Most residential heat pump installations take two to three days. This includes fitting the outdoor unit, running internal pipework and replacing or adding a hot water cylinder if the existing system does not have one.
Are heat pumps noisy?
A modern heat pump outdoor unit runs at a low hum, similar to a fridge, and sits outside the home. Placement during the survey keeps it clear of bedrooms and boundaries, and planning conditions in Ireland set noise limits that a registered installer works within.
How long does a heat pump last?
A well-maintained heat pump typically lasts fifteen to twenty years, comparable to or longer than an oil or gas boiler. An annual check keeps it running efficiently and protects any manufacturer warranty.
Do I need planning permission for a heat pump?
Air-to-water heat pumps are generally exempt from planning permission in Ireland, provided the unit meets certain size and noise conditions. Ground source systems may require permission depending on location. Your installer confirms requirements during the survey.
