Why the Register Is the Only Thing That Decides Your Grant
SEAI registered installers in Ireland fit heat pumps, solar panels, solar thermal and biomass boilers, and only a contractor on the register can process your grant application.
All 1,532 contractors listed here are drawn from the official SEAI registered contractor database rather than from applications to be listed, which is why registration is the one thing we can state about every single one of them. Choosing an installer who is not on it forfeits the grant entirely, worth up to €12,500 on a heat pump (as of July 2026).
Insulation comes first on any home energy upgrade, so a well-sealed house gets the most from a heat pump and the lowest running costs. From there you contact the installer directly using the phone number on their profile. There is no booking fee, no form standing between you and them, and we do not sell your details on.

SEAI Registered Installers — Common Questions
How many SEAI registered installers are there in Ireland?
1,532 contractors appear on the register across the 26 counties covered here, 688 of them for heat pumps and 795 for solar panels. Dublin has the most at 273; Longford the fewest at 15.
Do I have to use an SEAI registered installer?
For a grant, yes. SEAI requires grant-funded work to be carried out by a contractor on its registered contractor list, as set out in its home energy grant conditions on seai.ie. Check the current conditions with SEAI before you book, because work by an unregistered installer may not qualify.
Does the installer have to be in my county?
No. Registration is national rather than county by county, so a contractor listed under a neighbouring county can quote for your home and process the grant the same way. If your county is thin on a particular service, the county next door is the first place to look.
What does it cost to enquire?
Nothing. Phone numbers are published in full, you contact installers directly, and there is no booking fee. We do not sell your details on to anyone.
How up to date is this list?
The listings are drawn from the SEAI registered contractor database. Grant figures on the site were last checked against SEAI in July 2026. Installers do join and leave the register, so confirm registration with the contractor before committing to work.
Find SEAI Registered Installers in Your County
Listings are drawn from the SEAI register (checked July 2026). Confirm current registration before hiring, because SEAI requires grant-funded work to be done by a contractor on its registered contractor list. Pick your county above to see the full list with contact details.
Registration is the part worth checking first. A grant is paid on work carried out by a contractor on the SEAI register, so an installer who is not on it cannot process the claim at all. Every profile here is built from that register and carries the contact details published against the business.
