How to Find a Good Heat Pump Installer: The Complete Checklist
A comprehensive guide to finding a trustworthy, MCS certified heat pump installer in the UK. Learn what to look for, what questions to ask, and the red flags to avoid.

Choosing the right heat pump installer is one of the most important decisions you'll make when switching to renewable heating. A good installer will design a system that keeps your home comfortable while minimising running costs. A poor one could leave you with an undersized system, higher bills, and endless headaches.
Why MCS Certification Matters
The Microgeneration Certification Scheme (MCS) is the gold standard for heat pump installers in the UK. MCS certified installers have been independently assessed for technical competence, and their work is regularly audited for quality.
More importantly, you must use an MCS certified installer to qualify for the £7,500 Boiler Upgrade Scheme grant. Without MCS certification, you won't be able to claim the grant, which could add thousands to your total cost.
What to Look For in a Good Installer
Experience and Track Record
Ask potential installers how many heat pumps they've installed and request references from recent customers. An experienced installer will have completed hundreds of installations and should be happy to share customer testimonials and case studies.
Proper Heat Loss Survey
A reputable installer will always conduct a thorough room-by-room heat loss calculation before recommending a system. Be wary of any installer who quotes a system size based solely on the floor area of your home — this shortcut often leads to incorrectly sized systems.
Comprehensive Quote
A good quote should include:
- The heat pump unit and all associated components
- Any required radiator upgrades or underfloor heating
- Hot water cylinder (if needed)
- Controls and smart thermostat
- MCS certification and commissioning
- The BUS grant deducted from the total
- Warranty details for both equipment and workmanship
Aftercare and Maintenance
Ask about ongoing maintenance packages and what happens if something goes wrong. The best installers offer annual service plans and have their own engineers for warranty repairs rather than relying on third parties.
Red Flags to Watch Out For
Be cautious of installers who pressure you into signing quickly, offer unusually low quotes that seem too good to be true, or cannot provide their MCS certification number. Always verify an installer's MCS certification on the official MCS website before committing.
