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 Cork?
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.
What can Declan O'Connell Heating and Plumbing install?
They are registered with SEAI for heat pump installation and solar thermal. A contractor registered for more than one measure can fit them together and claim both grants, which saves coordinating two jobs.
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 Declan O'Connell Heating and Plumbing.
