## How Much Does a Heat Pump Cost?

Heat pump costs vary significantly based on the system type, home size, and installation complexity. This guide breaks down every cost component, compares air source and ground source options, and shows the 10-year total cost of ownership compared to conventional heating.

### Installation Cost by System Type

| System Type | Unit Cost | Installation | Total Installed | Best For |
|------------|-----------|-------------|----------------|----------|
| Air source (5-8 kW) | EUR 3,500-5,500 | EUR 3,500-5,500 | EUR 7,000-11,000 | Flats, small homes |
| Air source (8-14 kW) | EUR 5,000-8,000 | EUR 4,000-7,000 | EUR 9,000-15,000 | Average homes |
| Air source (14-20 kW) | EUR 7,000-11,000 | EUR 5,000-8,000 | EUR 12,000-19,000 | Large or poorly insulated |
| Ground source (borehole) | EUR 8,000-12,000 | EUR 10,000-18,000 | EUR 18,000-30,000 | Rural with garden space |
| Ground source (trench) | EUR 8,000-12,000 | EUR 7,000-12,000 | EUR 15,000-24,000 | Large gardens |

Air source heat pumps are the most popular choice for retrofits because they are less expensive and do not require garden excavation. Ground source heat pumps offer higher efficiency (SCOP 3.5-4.5 vs 2.5-3.5) but the extra cost rarely pays back in running cost savings alone.

### Cost Breakdown

| Component | Share of Total | Typical Range |
|-----------|---------------|---------------|
| Heat pump unit | 50-60% | EUR 3,500-11,000 |
| Installation labour | 20-25% | EUR 2,000-5,000 |
| Pipework and fittings | 10-15% | EUR 800-2,500 |
| Controls and thermostat | 3-5% | EUR 300-800 |
| Commissioning and certification | 3-5% | EUR 300-600 |
| Electrical supply upgrade | 0-5% | EUR 0-500 |

### Grant Deductions

| Country | Scheme | Grant Amount | Net Cost (8kW ASHP) |
|---------|--------|-------------|-------------------|
| UK | Boiler Upgrade Scheme | GBP 7,500 | GBP 3,000-6,500 |
| Ireland | SEAI Heat Pump Grant | EUR 3,500-6,500 | EUR 4,500-8,500 |
| Germany | BEG Funding | Up to 40% of cost | EUR 6,000-9,000 |
| France | MaPrimeRenov | EUR 3,000-5,000 | EUR 6,000-10,000 |
| Italy | Superbonus / Ecobonus | 50-65% tax deduction | EUR 3,500-7,500* |
| Netherlands | ISDE subsidy | EUR 3,000-4,500 | EUR 6,500-10,500 |

*Italian deductions are spread over 10 years of tax returns, not upfront savings.

### 10-Year Total Cost Comparison

| Heating System | Install Cost | Annual Running | Annual Service | 10-Year Total |
|---------------|-------------|---------------|----------------|--------------|
| Gas boiler (new) | EUR 3,000 | EUR 1,010 | EUR 80 | EUR 13,900 |
| Oil boiler (new) | EUR 4,000 | EUR 1,400 | EUR 120 | EUR 19,200 |
| ASHP (no grant) | EUR 11,000 | EUR 1,225 | EUR 150 | EUR 24,750 |
| ASHP (with EUR 5,000 grant) | EUR 6,000 | EUR 1,225 | EUR 150 | EUR 19,750 |
| ASHP + solar panels | EUR 17,000 | EUR 858 | EUR 200 | EUR 27,580 |

*Based on 100 sqm home, 14,000 kWh annual heating demand, 70 W/sqm heat loss.*

After grants, an air source heat pump reaches cost parity with gas heating within 10 years for most homes. The heat pump then continues operating for another 10-15 years with minimal maintenance.

## Frequently Asked Questions

### How much does a heat pump cost to install?

An air source heat pump costs EUR 7,000-16,000 fully installed for a typical home, depending on the heat pump size and complexity of the installation. Ground source heat pumps cost EUR 15,000-30,000 due to the additional borehole or trench costs.

### What grants are available for heat pumps?

The UK Boiler Upgrade Scheme provides GBP 7,500 towards an air source heat pump. Ireland's SEAI grant covers EUR 3,500-6,500. Germany offers up to 40% funding through BEG. France provides MaPrimeRenov up to EUR 5,000. Check your national scheme for current amounts and eligibility.

### What is included in the installation cost?

A typical quote includes the heat pump unit (60% of cost), installation labour, pipework modifications, controls and thermostat, commissioning, and MCS/equivalent certification. Extras that may not be included: radiator upgrades, hot water cylinder, electrical supply upgrade, and planning permission.

### Is a heat pump cheaper than a new gas boiler?

A new gas boiler costs EUR 2,000-4,000 installed, compared to EUR 7,000-16,000 for a heat pump. However, after grants (EUR 3,500-7,500), the gap narrows significantly. Over 15 years, heat pump total cost of ownership is often lower due to longer lifespan (20+ years vs 10-15) and lower maintenance.

### What ongoing maintenance costs should I expect?

Heat pump annual servicing costs EUR 100-200. There are no annual gas safety checks or flue inspections needed. Refrigerant checks are recommended every 2-3 years. Heat pumps have fewer moving parts than boilers and typically need fewer repairs over their 20-year lifespan.
