Air source heat pump installers near me: how to find and check one
The firms nearest to you are on the official register, not on this site. This guide shows you how to find them there, how to check the ones you find, and how to compare their quotes before you sign.
This is a checking guide, not a directory. It lists, rates and refers no installers.
- Certification number
- Technologies
- BUS registered: Yes / No
- Certification body
- Consumer code

Before you sign anything
Five checks that take minutes
Open each one; the ring keeps count.
1Find the firm on the MCS register
Search MCS "Find an installer" by name or certification number. No entry, no grant, and no MCS paperwork at the end. Using the register →
2Check it is certified for heat pumps
Certification is for each technology. A firm listed for solar panels is not, by that alone, certified to fit your heat pump. What MCS covers →
3Confirm its consumer code
Ofgem lists HIES, RECC and MCS for the grant. Check membership on the code's own site, not on the firm's website. The three codes →
4Ask for the design in writing
Room-by-room heat loss, the unit size and the flow temperature. A quote without them is a guess. Questions for the survey →
5Compare quotes line by line
Two or three quotes for the same design, with the grant shown as a deduction on each. Comparing quotes →
Why "near me" is the wrong first question
Distance is easy to find. Certification is what matters.
A map search shows the businesses closest to you, ordered by how near and how reviewed they are. It does not show whether a firm is certified to install heat pumps, whether it can apply for the grant, or whether it belongs to a consumer code that protects your deposit.
Those facts live on registers run by other organisations, and checking them costs nothing. Once you have done it for two or three firms, distance becomes a tiebreaker rather than the starting point. The page on using the MCS register walks through the search.
The register, field by field
What an MCS listing tells you
| Field | Why it matters |
|---|---|
| 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. |
Your protection if things go wrong
The three consumer codes Ofgem lists for the grant
Installers taking part in the Boiler Upgrade Scheme must be MCS certified and belong to a consumer code. What each code promises the homeowner is different, so it is worth knowing which one your installer is in.
RECC
Also CTSI approved. Members must give a workmanship warranty of at least 2 years with financial protection, and RECC offers dispute resolution at no cost to you.
MCS
Ofgem lists the MCS consumer code as relevant for the grant. It does not appear in the CTSI approved code list, so check exactly what it offers.
Check membership on the code's own site, not the firm's. More on what each code gives you.
Comparing quotes
Same job, or different jobs?
Quotes are only comparable when they price the same design. Line them up on the things that decide the job: the heat loss each installer calculated, the size of heat pump, the flow temperature, which radiators change and where the cylinder goes. If those differ, the cheaper quote may simply be for less work.
Then check the money. Each quote should show the grant as a deduction (£7,500 for most homes that qualify, on GOV.UK's eligibility page) and the total you pay. For context only, the official median price reported for grant-funded air source installations in July to September 2026 was £12,826 (DESNZ scheme statistics); your own price comes from your own survey. The quote comparison page has the full list.
It helps to see the price in three parts: the full price, the grant the installer takes off, and the stages in which you pay the rest. Agree those stages in writing, with the last payment due after commissioning, and your money keeps its leverage until the job is finished. The deposits and payments guide shows how the consumer codes protect a deposit.
Warning signs
Things the rules make easy to spot
- No MCS certification number, or one that does not list heat pumps.
- A request to pay the grant's share yourself while the application is going ahead. Installers must deduct it.
- Promises of a heat pump at no cost, or a grant promised as a certainty. The grant has eligibility rules and reduces a price you still pay.
- A TrustMark logo the firm is not listed under on TrustMark's own site.
- A firm claiming approval by government. There is no such status for heat pump installers.
All of these, and why they matter, on warning signs.
Common worries
"Checking sounds like a lot of work"
It takes minutes per firm. The register search, the consumer code check and the TrustMark check are each one search on a public website. The only checks that take longer are the ones that depend on the installer, such as the written design, and those you would want in any case.
"The nearest firm is booked up for months"
Registered firms often cover a wide region. The register shows the regions each firm works in, so widening your search does not mean giving up on checking.
"I have a quote already"
You can still check the firm. Use the check sheet to see what is outstanding before you sign.
The tool
The installer check sheet
Ten checks, from the register to the written terms, for up to three firms side by side. Tick each one as you confirm it yourself, and the sheet lists what is still outstanding for each firm. It keeps no scores, ranks no one and sends nothing anywhere. Print it and keep it with your quotes.

Finding and checking installers
How do I find air source heat pump installers near me?
Search the MCS register ("Find an installer") for heat pumps near your address or in your region, and use its filter for firms registered for the Boiler Upgrade Scheme. Map results and directories show businesses nearby; only the register shows whether a firm is certified for heat pumps.
Does this site recommend installers?
No. It lists, rates and refers no firms. It shows you how to find installers on the official register and how to check the ones you find.
Do I have to use an MCS certified installer?
For the grant, yes: only MCS certified installers who belong to a consumer code can apply for the Boiler Upgrade Scheme, which is £7,500 for most homes that own their property and replace fossil fuel or electric heating. MCS certification also produces the certificate a buyer of your home may ask for.
Is a TrustMark logo enough?
Check it on TrustMark's own Find a Business. TrustMark warns that some tradespeople show its logo without being registered. And TrustMark is not a substitute for MCS certification for heat pumps.
How many quotes should I get?
Two or three is usual. More useful than the number is that each is for the same design, with the heat loss, unit size and flow temperature written down, so the prices are comparable.
What if something goes wrong after the installation?
Go to the installer in writing first. If that fails, use the complaints and dispute route of the consumer code they belong to; RECC, for example, offers dispute resolution at no cost to the consumer.
