What areas does John Hennessy cover?

What grant can I claim on work by John Hennessy?
Grants may be available for eligible homes. SEAI lists support of up to €1,800 for solar panels as of July 2026, and SEAI decides eligibility. Confirm how the application and payment work with John Hennessy and with SEAI before any work starts.
Does my home in Kerry qualify for a grant?
A home built and occupied before 2021 usually qualifies. Housing across Kerry 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 Kerry?
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.

SEAI Heat Pump Grant for Work by John Hennessy
SEAI support for a heat pump is up to €12,500 (as of July 2026) for eligible homes. Ask John Hennessy how the grant application and payment would work for your job, and confirm the details with SEAI before any work starts.
It is worth knowing how the total breaks down before the survey. The heat pump itself carries €6,500, a Renewable Heat Bonus applies where you are replacing an oil, gas, solid fuel or electric storage system, and a further amount goes towards heating system upgrades such as new radiators. Asking for the quote to set those out separately makes the net figure clear rather than leaving it to be worked out later.
