SEAI-Registered Installers in Donegal
SEAI registered installers in Donegal fit heat pumps, solar panels, solar thermal and biomass boilers that replace oil and gas and heat your home from renewable energy.
All 71 SEAI registered installers in Donegal listed here appear on the official SEAI contractor register, which is the one thing that decides whether you can claim your grant.
Donegal's large and dispersed rural housing stock, much of it exposed and on oil, sees strong demand for heat pump and biomass upgrades, with solar PV growing. Installers on this page cover Letterkenny, Donegal town, Buncrana, Ballybofey and Bundoran and the wider county. Bordering counties are served too, including Leitrim.
Choosing an installer on the SEAI register matters because only a registered contractor can process your grant, 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 in Donegal gets the most from a heat pump and the lowest running costs.
Of the 71 contractors covering Donegal, 35 for heat pumps, 34 for solar panels, 4 for solar thermal and 2 for biomass boilers. 3 are registered for more than one measure, which matters if you are pairing a heat pump with solar panels, since a single contractor can then do both jobs and claim both grants rather than you coordinating two.

Widening the Search Beyond Donegal
Registration is national rather than county by county, so a contractor listed under a neighbouring county can quote for a home in Donegal and process the grant the same way. If Donegal is thin on a particular service, the county next door is the first place to look.
It is worth doing even when Donegal has plenty of choice. Two or three quotes on the same specification is the only reliable way to see what the work should cost, and lead times vary a lot between firms in Ulster depending on how booked up they are. Ask each one whether the price includes the grant paperwork and any radiator or cylinder work, since that is where quotes most often differ rather than on the heat pump itself.

The 71 contractors listed above cover Donegal rather than a single town, so any of them will quote for these areas. Check your own address when you call, since a few work a tighter radius than the county.

SEAI Registered Installers in Donegal — Common Questions
How many SEAI registered installers are there in Donegal?
71 contractors on the SEAI registered installer list cover Donegal, 35 of them for heat pumps and 34 for solar panels. Every one is listed on this page with contact details, so you can approach them directly.
Do I need an SEAI registered installer to get a grant in Donegal?
Yes. Every one of the 71 contractors on this page is on that register, which is why they are here — the list is drawn from the register itself rather than from applications to be listed. Using an installer who is not on it means the grant cannot be claimed at all, whatever the quality of the work. In Donegal that matters most for heat pumps, where 35 of the 71 are registered for the measure.
How much is the heat pump grant worth in Donegal?
Up to €12,500 as of July 2026, made up of €6,500 for the heat pump, €4,000 as the Renewable Heat Bonus for replacing oil, gas or solid fuel, and €2,000 towards radiators and pipework. Reaching the full amount depends on the house, not the county. Exposed sites and long heating seasons make insulation the first priority, before the heat pump grant is applied.
Which towns in Donegal do these installers cover?
Between them the listed contractors take work across the county, from Letterkenny, Donegal town, Buncrana, Ballybofey and Bundoran and the smaller towns and villages in between. Most cover the whole of Donegal rather than one town, so it is worth asking about your own address when you call.
Can installers from counties bordering Donegal do the work?
They can. Registration is national, not county by county, so a contractor listed under Leitrim can quote for a home in Donegal and process the grant exactly the same way. If you are near the border it is worth getting quotes from both lists.
Does my Donegal home qualify for an SEAI grant?
A home built and occupied before 2021 usually qualifies. Donegal's large and dispersed rural housing stock, much of it exposed and on oil, sees strong demand for heat pump and biomass upgrades, with solar PV growing. A registered installer confirms eligibility during a free survey before any work is committed, and insulation comes first on any upgrade, since a well-sealed house gets the most from a heat pump.
The Other Trades a Donegal Retrofit Needs
A renewable heating upgrade rarely happens on its own, and the order the work goes in decides what it costs. These are SEAI-registered trades covering Donegal on our sister sites, each one worth lining up before the heating work starts rather than after.
- Before the heating work Attic and wall insulation in Donegal Insulate before you heat. A well-sealed home needs a smaller heat pump and costs less to run, and insulation carries SEAI grants of its own.
- Alongside the installation Plumbers and gas installers in Donegal Taking out an old oil or gas boiler, reworking the heating circuit and fitting the hot water cylinder is a registered plumber’s job, and a heat pump needs an RGI plumber to commission it.
