Searching the register
MCS, the Microgeneration Certification Scheme, publishes a search, open to anyone at no charge, called "Find an installer". It can be used in several ways:
- By name or certification number, when you already have a firm in mind, for example from a leaflet or a recommendation.
- By technology near an address, which is the closest thing to "installers near me". Choose heat pumps and enter your address or postcode.
- By nation and region, which returns every firm that covers your area, not only those based nearby.
There is also a filter for firms registered for the Boiler Upgrade Scheme. If you want the grant, switch it on: it removes firms that cannot apply for you.
Reading a listing
| Field | What it tells you |
|---|---|
| Certification number | The number to quote when you check the firm again, and the one that should appear on its paperwork. |
| Technologies | Certification is for each technology. A firm certified for solar panels is not, by that alone, certified for heat pumps. |
| Regions covered | Whether the firm works where you live. It says nothing about quality. |
| Registered for the Boiler Upgrade Scheme | Yes or No. A firm must be registered to apply for the grant for you. |
| Certification body | The organisation that certified the firm and that you can approach about its certification. |
| Contact details and address | Compare them with the quote. A mismatch is worth a question. |
Why "per technology" matters
A firm is certified for each technology separately. Plenty of firms are certified for solar panels and batteries and not for heat pumps, or the other way round. A firm's listing shows its technologies, and that is the line to read first. A heat pump fitted by a firm not certified for heat pumps does not qualify for the grant and does not get an MCS certificate.
Since 28 April 2026, MCS is the only certification the grant scheme accepts. Older material sometimes mentions other schemes for heat pump installers; for the grant, they no longer count.
What the register cannot tell you
The register confirms certification and grant registration. It does not tell you:
- whether the firm designs well, or will size your system to a proper heat-loss calculation;
- whether its prices are fair for your job;
- how it deals with customers, or how quickly it fixes problems;
- which consumer code it belongs to (check that on the code's own site).
Those come from the survey, the quote and the written terms, which is why the check sheet goes beyond the register.
From a list to a shortlist
A search near a town can return dozens of firms. To get to two or three worth inviting for a survey, it helps to work in order. First, keep only firms certified for heat pumps and registered for the grant. Then confirm each one's consumer code on the code's site. Then, if a firm advertises TrustMark, check that too. Distance and availability can decide between firms that pass all of those.
Ask each shortlisted firm for a survey and a written design. The page on questions for the survey visit covers what to ask while they are in the house, and comparing quotes covers what to do when the quotes arrive.
This site does not list or recommend installers. The register is the place to find them, and every check here costs nothing to do.
Near an address, or by region?
Searching near your address gives you firms based close by. Searching by nation and region gives you every firm that says it covers your area, which can include firms based further away. The second search is usually longer but more useful, especially outside cities, because many heat pump installers travel. The regions field on each listing tells you where a firm works.
Keeping a record
Registers change as firms join, leave or change what they are certified for. When you check a firm, note the date and the details you saw: certification number, technologies, grant registration and certification body. The check sheet has space for this. If anything changes between your check and the job, you will know.
Firms that subcontract
Some firms sell the job and pass the installation to another business. Ask which business will carry out and sign off the work, and check that business on the register too. The firm whose certification number goes on the MCS certificate is the one that matters for the grant.
What to do with the shortlist
Contact each shortlisted firm, explain what you want, and ask for a survey. Tell each one you are getting more than one quote and that you would like the heat-loss figures and design in writing. Note which firms reply promptly and clearly; that is useful evidence about how they will deal with you later. Then use the check sheet to keep track of what you have confirmed for each.
Regions on the register
Each register entry lists the regions a firm says it covers. Treat that as a starting point rather than a promise: a firm covering a whole region may still be selective about distance, and a firm just outside your area may be happy to travel. Ask each one how far it goes for surveys, for the installation and for servicing afterwards. Aftercare matters with a heat pump, because the first winter is when settings are fine-tuned, and an installer several hours away may be slower to return.
Finding a certified firm is the first step rather than the last: check an installer covers the other checks, consumer codes explains the codes listed beside each firm, and comparing quotes shows how to set two or three quotes side by side.
