How much does a heat pump installation cost?

After the SEAI grant, a heat pump often costs less than a new gas boiler. A three-bed semi-detached usually comes to about €2,000 to €3,000 after the grant. The price depends on the size of your home and its BER rating. We help you with the grant, and every quote is free and in writing after a site visit.

Is my home suitable for a heat pump?

Insulation levels and your existing heat distribution system are the main factors. We carry out a full site survey before quoting, and every customer receives a written report on how the system would perform in their home.

What brands of heat pump do you install?

We install Viessmann and Grant heat pumps, chosen for their price, quality and the availability of parts.

Can you help me apply for the SEAI heat pump grant?

Yes. As an SEAI registered installer, we can help you with your heat pump grant.

What warranty do I get on the heat pump?

You get a 12-month warranty on our workmanship, plus a 5-year warranty on the heat pump. We register it for you. It needs a service every year to stay valid.

Do you install heat pumps in Wicklow as well as Dublin?

Yes. We cover from Ballsbridge south as far as Wicklow town. South Wicklow is a growing market for heat pumps because many homes there currently heat with oil and the grants to switch are large.

Air-to-water heat pumps

Heat pumps, fitted by a local family team

An air-to-water heat pump takes warmth from the outside air and moves it into your home through your heating system, replacing your gas or oil boiler.

Every home is different. Insulation and your existing heating decide how well a heat pump works, so we survey both before we quote, and every customer gets a full written report on the house and how the system should perform.

Heat pumps are our main focus Most of the work we do now is heat pump installs.

"Superb service from David (Junior), went out of his way to do an excellent job replacing our boiler in a difficult situation made worse by the poor job done by the previous installer. Impressive technical knowledge and skill and good communication. Recommended. Review well out of date due to Google's oversensitive policies"

"Really top class service and a lovely bloke, I phoned him, he advised me to text him my details and then arranged a day and time to visit, which he did, this might sound basic but a lot of lads won't even do this! On arrival, it was very clear and evident that he knew his stuff, his knowledge and experience were clear. He not only completely fixed my issues ( boiler problem and 2 rads) he actually spotted an existing leak and fixed this. I'd 100% recommend him and il deffo be using him again."

Why switch to a heat pump

€14,500

In SEAI grants for a house

Up to €14,500, including €2,000 for scrapping your old oil or gas boiler. Apartments up to €11,500. For homes built and occupied before 2021. We are SEAI registered. Grant figures from SEAI, October 2026.
3.5–5×

The heat for the electricity it uses

For every unit of electricity it uses, a heat pump gives you three and a half to five units of heat.
No more oil deliveries

No tank to fill, no delivery to book and no kerosene price shocks.
Steady warmth in every room

It runs gently and evenly, so rooms stay at a steady temperature instead of swinging between hot and cold.
Far lower carbon emissions

For each unit of heat, a heat pump gives off about a fifth of the CO₂ of an oil boiler, and it falls further as more of Ireland’s electricity comes from renewables.
A better BER

One of the biggest single upgrades to your home’s energy rating. Running costs are lowest in a well-insulated home, and the survey tells you where yours stands.
