Step-by-Step Career Path
Get Plumbing Qualifications
Start with NVQ Level 2/3 in Plumbing & Heating. Heat pumps connect to existing heating systems, so understanding pipework, radiators, and underfloor heating is essential.
Add Electrical Skills
Heat pumps require electrical connections. Get your 18th Edition Wiring Regulations certificate. Full electrical qualifications (NVQ Level 3) are ideal but not always required.
Learn F-Gas Certification
Heat pumps contain refrigerant gases. F-Gas Category 1 certification is required to handle refrigerants legally. This involves understanding refrigeration cycles and safe gas handling.
Complete Heat Pump Training
Specialist heat pump courses cover air source, ground source, and hybrid systems. Learn about heat pump sizing, installation, commissioning, and maintenance from manufacturers like Mitsubishi, Daikin, and Vaillant.
Get MCS Certification
MCS (Microgeneration Certification Scheme) is required to install heat pumps eligible for government grants. Your employer needs MCS accreditation, which requires trained installers.
Enter the Growing Market
