Heat pump price guide by home type
Apartment, terraced, semi detached and detached: typical installed prices before and after grants.
Short answer
Before grants, expect roughly €10,000 to €14,000 for an apartment and €14,000 to €23,000 for a house. After SEAI grants most houses land between €500 and €8,500. Use the estimator for a range based on your own home's age, size and BER.

Why ranges, not a single price
Two semis on the same road can have very different quotes. The heat pump itself is a fraction of the cost; radiators, pipework, the cylinder and access make up the rest. The low end is a well insulated home that needs few radiator changes; the high end is an older home that needs most of them.
Dublin housing stock
Georgian and Victorian redbrick homes in the inner suburbs usually sit at the top of the range. 1970s to 90s estates and newer homes often sit at the bottom. See the area pages for local ranges.
