A1 Plumbing & Heating, Common Questions
Is A1 Plumbing & Heating SEAI-registered?

What areas does A1 Plumbing & Heating cover?
A1 Plumbing & Heating is based in Donegal and takes work across the county, including Letterkenny, Donegal town, Bundoran, Buncrana, Ballybofey, Dungloe, Killybegs and Carndonagh. Most installers cover their whole county rather than one town, so it is worth confirming your own address when you call.
Do I need to use an installer based in Donegal?
No. SEAI registration is national rather than county by county, so a contractor listed under a neighbouring county can quote for your home and handle the grant the same way. Getting two or three quotes is the only reliable way to see what the work should cost.
Does A1 Plumbing & Heating only do heat pump installation?
On the SEAI register they are listed for heat pump installation. They may well do other work, but heat pump installation is the measure their registration covers, so it is the one they can process a grant for.
Should anything be done before the installation?
Insulation comes first on any home energy upgrade. A well-sealed house needs a smaller system and runs at a lower cost, and attic and wall insulation carry SEAI grants of their own. Ask about the fabric of the house when you speak to A1 Plumbing & Heating.
