Frequently Asked Questions
How much do heat pump engineers earn?▼
Qualified heat pump engineers earn £32,000-£45,000 employed, rising to £42,000-£55,000+ with experience. Self-employed installers charge £200-£500+ per day. The skills shortage means premium rates, and successful businesses can achieve £150,000+ annual revenues.
Do I need plumbing qualifications first?▼
Yes, heat pump installation requires solid plumbing and heating knowledge. Most successful heat pump engineers start with Level 3 plumbing and heating, then add F-Gas and heat pump-specific training. The combination is essential for proper installations.
How long does it take to become qualified?▼
For qualified plumbers, adding heat pump skills takes 6-12 months including F-Gas certification, heat pump training, and MCS assessment. Complete newcomers need 18-24 months to gain all necessary qualifications and experience.
Are heat pumps just a temporary trend?▼
No, it's a permanent transition. The government has mandated no gas boilers in new homes from 2025 and all heating to be low carbon by 2035. Heat pumps are the only viable replacement for gas boilers at scale. This represents a complete industry transformation.
What's the biggest challenge in heat pump installation?▼
System design and optimization for existing homes. Unlike gas boilers that can be "dropped in," heat pumps require careful sizing, system design, and often building improvements. Understanding whole-house energy performance is crucial for successful installations.
