Heat pumps

What a heat pump really costs to install in Dublin

Typical prices by home type, before and after SEAI grants, and the extras that push a quote up.

Short answer

A whole home air to water heat pump typically costs €14,000 to €23,000 installed for a Dublin house before grants. SEAI grants of up to €14,500 bring most houses down to roughly €500 to €8,500. Older homes cost more because they usually need radiator and insulation work too.

Getting a fair quote

Ask for at least three written quotes. Each should include a room by room heat loss calculation, the heat pump model and its SCOP, and a clear list of radiators being changed. A quote without a heat loss calculation is a guess.

Why quotes for the same job vary by thousands

Homeowners regularly report quotes €5,000 or more apart for the same house. Local installers quoting directly are often well below national firms, and a One Stop Shop can come in higher than going direct for a job that only involves a heat pump and radiators. A One Stop Shop makes more sense for a deep retrofit with insulation and windows too.

Ask each installer how the grant is handled. Some do the paperwork and invoice you the net price; others expect you to pay in full and claim the grant yourself. Get it in writing either way, including who is responsible if the grant claim is delayed or refused.
