Heat Pump Installer
A heat pump installer designs, installs, and commissions air source and ground source heat pump systems. As the UK transitions away from fossil fuel heating, heat pumps are becoming the primary low-carbon alternative for home heating and hot water.
What does a heat pump installer do?
Heat pump installers handle the full process of transitioning to heat pump heating, including:
- Heat loss surveys and system design
- Air source heat pump (ASHP) installation
- Ground source heat pump (GSHP) installation
- Radiator upgrades and sizing for lower flow temperatures
- Underfloor heating integration
- Hot water cylinder installation and configuration
- Smart controls and weather compensation setup
- MCS certification and grant application support
Is heat pump installation regulated in the UK?
Yes. To access government grants such as the Boiler Upgrade Scheme (BUS), heat pump installers must be certified under the Microgeneration Certification Scheme (MCS). MCS certification ensures the installer follows industry standards for system design and installation quality.
Heat pump installations also require compliance with Building Regulations (Part L for energy efficiency, Part P for electrical work). Installers working on the refrigerant circuit must hold an F-Gas qualification. Most reputable installers also carry BPEC or City & Guilds heat pump qualifications. A proper energy assessment can help determine whether your home would benefit from improved insulation before installing a heat pump.
The BUS grant currently provides £7,500 towards air source heat pump installations (subject to eligibility — the installer typically applies on your behalf). Heat pump installations benefit from 0% VAT (currently extended to March 2027).
What to look for when hiring a heat pump installer
When choosing a heat pump installer, consider:
- MCS certification — Essential for accessing the BUS grant and a strong indicator of competence.
- Detailed heat loss survey — A proper survey is critical. Avoid any installer who quotes without visiting your property and assessing insulation, room sizes, and current heating.
- Manufacturer training — Installers trained by specific heat pump manufacturers (Vaillant, Daikin, Mitsubishi, etc.) offer better installation and aftercare.
- Full system design — The quote should cover the heat pump, cylinder, radiator upgrades, controls, and any electrical work needed.
- Aftercare package — Heat pumps benefit from annual servicing. Ask about ongoing support and maintenance contracts.
Frequently Asked Questions
How much does a heat pump cost?
An air source heat pump system typically costs £8,000–£15,000 fully installed, before the £7,500 BUS grant (subject to eligibility). Ground source systems cost £15,000–£35,000 due to the ground works required. Costs include the heat pump unit, hot water cylinder, controls, and any radiator upgrades.
Will a heat pump work in my home?
Heat pumps work in most UK homes but are most efficient in well-insulated properties. Older homes may need insulation improvements and radiator upgrades for lower flow temperatures. A proper heat loss survey will determine suitability and identify any preparatory work needed.
