What areas does Johnny Hewetson Ltd cover?
Johnny Hewetson Ltd is based in Kilkenny and takes work across the county, including Kilkenny city, Callan, Thomastown, Castlecomer, Graiguenamanagh and Urlingford. Most installers cover their whole county rather than one town, so it is worth confirming your own address when you call.
Does my home in Kilkenny qualify for a grant?
A home built and occupied before 2021 usually qualifies. Housing across Kilkenny varies a lot, so the survey decides rather than the county. A registered installer confirms eligibility during a free survey before anything is committed.
Do I need to use an installer based in Kilkenny?
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 Johnny Hewetson Ltd 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.
