What is an MCS heat pump installer?
An MCS heat pump installer is an installation company with MCS certification relevant to one or more heat pump technologies.
The term is useful because MCS covers a wider range of renewable and low-carbon technologies. A company being an MCS certified installer does not automatically mean it installs heat pumps.
When researching companies, the technology recorded against the installer is therefore an important part of the picture.
Which heat pump technologies appear in MCS installer data?
Heat pumps are not represented by a single technology category. Installer information can distinguish between several types of system.
Technology fields available within MCS installer data can include:
- ASHP - air source heat pumps
- GSHP - ground source heat pumps
- EAHP - exhaust air heat pumps
- GAHP - gas absorption heat pumps
- SAHP - solar assisted heat pumps
- WSHP - water source heat pumps
This is why simply searching for a general list of MCS installers can be too broad when your real objective is to identify businesses working with a particular type of heat pump.
Our MCS Certified Installers UK guide covers the wider range of renewable technologies found across the installer market.
MCS air source heat pump installers
Air source heat pumps are commonly abbreviated to ASHP. When researching MCS installer information, an ASHP technology field can help identify companies associated specifically with air source heat pump installation.
This is more precise than assuming every company that mentions heat pumps offers the same systems.
For homeowners, the practical considerations will include whether the company serves the property location and whether its current certification is appropriate for the proposed installation.
For businesses, ASHP information can be useful for identifying a defined segment of the UK installer market for supplier research, partnerships, industry mapping or market analysis.
MCS ground source heat pump installers
Ground source heat pumps are commonly abbreviated to GSHP. Companies associated with GSHP installation form a distinct group that can overlap with, but should not automatically be treated as identical to, air source heat pump installers.
An installation company may be associated with both ASHP and GSHP technologies, while another may appear against only one.
If you are building a targeted list of ground source heat pump companies, checking the GSHP field directly is therefore more useful than filtering only for general renewable installers.
What to check when researching a heat pump installer
The right installer depends on more than whether the company appears within the wider MCS market. Useful information to review includes:
- Installer name - identify the company associated with the listing.
- Heat pump technology - determine whether the installer is associated with ASHP, GSHP or another relevant heat pump category.
- Certification number - useful when identifying and checking installer information.
- Certification body - review the certification information recorded for the company.
- Address and postcode - useful for geographical research.
- Service regions - identify areas in which the company indicates it operates.
- Contact information - website, telephone and email information can support further research.
Where current certification is important to a project, purchasing decision or eligibility requirement, verify the company's current status before proceeding.
How to find MCS heat pump installers
The most appropriate search method depends on why you are looking for an installer.
A homeowner will normally want to find installers serving their location, narrow the results to the relevant heat pump technology and then investigate individual businesses before requesting quotations.
Businesses often have a broader requirement. A manufacturer, distributor, software provider, consultant or other organisation may need to identify many heat pump installers across the UK rather than choose one company for a single installation.
Structured data is useful in that situation because installers can be filtered by technology and geography before further research or outreach takes place.
For the different ways of approaching the search, see our guide to finding MCS certified installers.
Researching the UK heat pump installer market
MCS installer information can also be used to research the structure of the UK heat pump installation market.
Potential business use cases include:
- Identifying air source heat pump installation companies
- Building lists of ground source heat pump installers
- Comparing installer coverage across UK regions
- Finding companies associated with multiple heat pump technologies
- Supplier and distribution research
- Partnership research
- Renewable energy market analysis
The ability to separate ASHP, GSHP and other heat pump technologies is particularly useful for this type of research because it prevents a broad renewable installer list from being treated as a heat pump-specific market.
Heat pumps are one part of the wider MCS installer landscape. If your research extends into other renewable technologies, our MCS solar installers guide covers Solar PV, while the complete MCS installer guide provides the broader overview.
