Heat Pump Installation Cost in Dublin 2026 (After Grants)

In brief: A typical air-to-water heat pump for an Irish 3-bed semi costs about €15,000 to €17,200 including 9% VAT, before grants. A house switching from oil or gas can get up to €14,500 back from SEAI, so the net cost often falls to a few thousand euro. What you pay depends mostly on your radiators, your insulation and how much pipework needs changing.

How much does a heat pump cost in Dublin?

In brief: Published typical prices for a full air-to-water install in an Irish semi-detached house range from about €15,000 to €18,000 including VAT. There is no official Dublin price list; the figures below are national.

Source	Home	Typical price, incl. VAT	What it includes
Bord Gáis Energy	100 m² 3-bed semi	€17,200	4 kW monobloc heat pump, 200 litre cylinder, installation
Money Guide Ireland	Typical home	€16,000 to €18,000	Includes new internal pipework where needed
Irish Times (September 2026)	Typical home	about €15,000	Depends on the work and house size

What you pay after grants: two worked examples

In brief: Leaving oil or gas with new radiators unlocks the full €14,500. A house with radiators that already work at heat pump temperatures gets less grant, but also needs less work.

Example 1: 1970s semi in Dublin 12, oil boiler, radiators need replacing. Earlier insulation upgrades gave the house a BER with a Heat Loss Indicator under 2.3, so no technical assessment is needed.

Line	Amount
Installer quote, incl. VAT	€17,200
Heat pump system grant	minus €10,500
Central heating upgrade grant	minus €2,000
Boiler scrappage grant	minus €2,000
You pay	€2,700

Example 2: 2008 semi in Swords, gas boiler, existing radiators are adequate. No technical assessment needed because the house was built after 2007.

Line	Amount
Installer quote, incl. VAT	€15,000
Heat pump system grant	minus €10,500
Boiler scrappage grant	minus €2,000
You pay	€2,500

Both quotes are illustrative, based on the published typical prices above. Both homes also pay for a post-works BER, with €50 back from SEAI. Your quote will differ. See the SEAI heat pump grant guide for every condition.

What drives the price up or down?

• Radiators and pipework: radiators sized for hotter boiler water often need replacing for a heat pump. This is usually the biggest variable.
• Heat pump size: a well insulated home needs a smaller unit. An oversized unit costs more to buy and runs less efficiently.
• Hot water cylinder: a 200 litre cylinder is typical for a family home; it needs a space roughly the size of a hot press.
• Insulation upgrades: if a technical assessment requires attic or wall insulation, that is extra, though separately grant aided for homes built before 2011.
• Access and siting: a long pipe run from the outdoor unit, scaffolding, or a terraced house with no side access adds labour.
• System type: an air-to-air system for a few rooms costs differently from a full air-to-water system. See air-to-water vs air-to-air.

Costs that are often left out of the quote

• Technical assessment for pre-2007 homes without a qualifying BER (€200 comes back with the grant).
• Post-works BER certificate, required before SEAI pays (€50 comes back).
• Removing the old boiler and oil tank.
• Electrical work, if your fuse board needs changes.
• Making good: plastering, flooring and decorating where pipes were run.
• Management company approval in apartments.

Ask every installer to list these as separate lines.

Why do Dublin quotes vary so much?

In brief: Because installers quote different scopes. One quote may include new radiators, the cylinder, removal of the oil tank and the BER; another may not. Compare the gross price for the same scope, not the "after grant" headline.

Red flags: a quote that only shows the price after grants, no heat loss calculation, or a unit size picked without visiting the house.

Can I spread the cost?

The Government backed Home Energy Upgrade Loan Scheme offers low cost loans for energy upgrades through participating lenders. One Stop Shops can also arrange finance and deduct grants upfront.

FAQ

Is €17,000 a normal price for a heat pump? For a 3-bed semi with new radiators and a cylinder, yes, it is within the published typical range. Ask what is included before comparing.

Is a heat pump cheaper than a new gas boiler? Upfront, no. After grants the gap narrows sharply, and running costs decide the rest. SEAI gives no grant for a new gas or oil boiler.

Does VAT apply to heat pumps? Yes, at 9% for supply and installation since January 2025. Most quotes include it.
