Greentherm Ltd, Common Questions

How do I get a quote from Greentherm Ltd?
Contact Greentherm Ltd directly using the phone number on this page. Nothing goes through us, there is no booking fee, and your details are not passed to anyone else or sold on.
What areas does Greentherm Ltd cover?
Greentherm 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.
What can Greentherm Ltd install?
They are registered with SEAI for heat pump installation and solar thermal. A contractor registered for more than one measure can fit them together and claim both grants, which saves coordinating two jobs.
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 Greentherm Ltd.
What grant can I claim on work by Greentherm Ltd?
Because they are on the SEAI register, work carried out by Greentherm 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.
The Other Trades a Dublin 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 Dublin on our sister sites, each one worth lining up before the heating work starts rather than after.
