What areas does Dennehy Bros Heating & Plumbing Ltd cover?
Dennehy Bros Heating & Plumbing Ltd is based in Galway and takes work across the county, including Galway city, Oranmore, Athenry, Tuam, Ballinasloe, Loughrea, Clifden and Salthill. 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 Dennehy Bros Heating & Plumbing Ltd.
What grant can I claim on work by Dennehy Bros Heating & Plumbing Ltd?
Because they are on the SEAI register, work carried out by Dennehy Bros Heating & Plumbing Ltd is grant-eligible. SEAI pays up to €12,500 for the full heat pump package as of July 2026. The installer applies on your behalf and you pay the balance after the grant is deducted.
Does my home in Galway qualify for a grant?
A home built and occupied before 2021 usually qualifies. Housing across Galway varies a lot, so the survey decides rather than the county. A registered installer confirms eligibility during a free survey before anything is committed.
