What areas does John O Sullivan Electrical cover?
John O Sullivan Electrical is based in Cork and takes work across the county, including Cork city, Ballincollig, Carrigaline, Midleton, Mallow, Bandon, Cobh, Fermoy, Kinsale and Macroom. 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 Cork qualify for a grant?
A home built and occupied before 2021 usually qualifies. Housing across Cork 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 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.
Does John O Sullivan Electrical 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.

SEAI Heat Pump Grant for Work by John O Sullivan Electrical
SEAI support for a heat pump is up to €12,500 (as of July 2026) for eligible homes. Ask John O Sullivan Electrical 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.
