What areas does McCarthy Plumbing cover?
McCarthy Plumbing 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.
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 McCarthy Plumbing.
What grant can I claim on work by McCarthy Plumbing?
Because they are on the SEAI register, work carried out by McCarthy Plumbing is grant-eligible. SEAI pays up to €1,200 for solar water heating as of July 2026. The installer applies on your behalf and you pay the balance after the grant is deducted.
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.
The Other Trades a Cork Retrofit Needs
A renewable heating upgrade rarely happens on its own, and the order the work goes in decides what it costs. These are SEAI-registered trades covering Cork on our sister sites, each one worth lining up before the heating work starts rather than after.
