Can you easily find people who actually know how heat pumps work?

That's a really good question, and the answer is becoming much easier than it used to be, but it's still a different landscape than finding a gas boiler engineer.

Here's a breakdown of the situation regarding finding qualified ASHP service and repair technicians, particularly in Scotland:

1.      The Growth of the Market:

Increased Demand: With the push for net-zero and government incentives (like the Scottish Grants), heat pump installations are soaring. This rapid growth is driving an increase in the number of trained and qualified installers and maintenance engineers.

Training & Accreditation: More training courses are available, and the Microgeneration Certification Scheme (MCS) is crucial. MCS certification covers both the installation and the ongoing quality of work for renewable technologies like air source heat pumps. Always ensure any installer or repair company is MCS certified. This is your guarantee of competence and is often a requirement for accessing grants and warranties.

2.      Where to Look (and what to look for):

Your Original Installer - this is by far your best first port of call. A reputable MCS-certified installer will typically offer:

Installation warranty: Covering their workmanship for a period (e.g. 1-2 years).

Manufacturer warranty: Covering the heat pump unit itself (e.g. 5-7 years for parts).

Annual servicing: They will usually offer an annual service package, which is crucial for maintaining efficiency and keeping your warranty valid.

Breakdown support: They are generally best equipped to diagnose and repair issues with the systems they installed, as they know the specifics of your setup and have direct contact with the manufacturer.

Manufacturer Approved Service Engineers: Major heat pump manufacturers (e.g. Vaillant, Viessmann, Daikin, Mitsubishi Electric, Worcester Bosch) have networks of approved service partners. If your original installer goes out of business or you move house, you can often find these approved technicians through the manufacturer's website. They will have specific training on that brand's equipment.

MCS Installer Search: The MCS website has a "Find an Installer" tool. While primarily for installations, many installers also offer service and repair. You can search by postcode.

Renewable Energy Associations: Organisations like the Heat Pump Association (HPA) or regional renewable energy bodies in Scotland can sometimes provide lists of qualified professionals.

3.      The Skillset Required:

Air source heat pumps are more complex than traditional boilers. An engineer needs:

Refrigerant Handling (F-Gas Certification): This is essential for anyone working on the refrigerant circuit. It's a legal requirement.

Electrical Competence: Heat pumps are high-power electrical appliances.

Plumbing & Heating System Knowledge: Understanding the wet heating system (radiators, pipework, hot water cylinder) is crucial.

Controls Expertise: Heat pump controls can be sophisticated, requiring specific training.

Manufacturer-Specific Training: Each brand has its nuances, so approved installers trained by particular manufacturers are often best.

So, yes, you can absolutely find people who know how to service and repair these systems in Scotland, including your area.

The key is to:

• Prioritise MCS-certified companies.

• Ask about their specific heat pump experience and qualifications (e.g. F-Gas).

• Choose an installer who offers a comprehensive annual service plan. 

This proactive approach will help prevent breakdowns and ensure you have a trusted contact for any issues.
