J&D O'Brien Ltd, Common Questions
Is J&D O'Brien Ltd SEAI-registered?
Yes. J&D O'Brien Ltd appears on the official SEAI registered contractor database for heat pump installation in Dublin, which is what allows them to carry out grant-eligible installations and process your SEAI grant application.

What areas does J&D O'Brien Ltd cover?
J&D O'Brien Ltd is based in Dublin and takes work across the county, including Dublin city centre, Finglas, Clontarf, Rathfarnham, Tallaght, Blanchardstown, Swords, Malahide, Dún Laoghaire and Bray. 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 J&D O'Brien Ltd.
What grant can I claim on work by J&D O'Brien Ltd?
Because they are on the SEAI register, work carried out by J&D O'Brien 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 Dublin qualify for a grant?
A home built and occupied before 2021 usually qualifies. Housing across Dublin 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 Dublin Retrofit Needs
