Phoenix Hill Limited / TriNRG, Common Questions
Is Phoenix Hill Limited / TriNRG SEAI-registered?

What areas does Phoenix Hill Limited / TriNRG cover?
Phoenix Hill Limited / TriNRG is based in Mayo and takes work across the county, including Castlebar, Westport, Ballina, Claremorris, Knock, Belmullet, Crossmolina and Swinford. 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 Mayo?
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 Phoenix Hill Limited / TriNRG only do solar PV panel installation?
On the SEAI register they are listed for solar PV panel installation. They may well do other work, but solar PV panel 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 Phoenix Hill Limited / TriNRG.
