Is the Samsung EHS Quint MCS Certified?
Quick answer
At the time of writing, we have not found a listing for the Samsung EHS Quint in the MCS Product Directory, under either the product name or the outdoor model references Samsung publishes on its GB pages. That does not prove certification is not in the pipeline somewhere, but nobody should be telling you the Quint is MCS certified as settled fact. If you are being quoted one, ask for the listing and check it yourself.
Current status
Current status, checked 6 August 2026
Samsung has public GB product information for the EHS Quint, including model references and technical data. However, Heat Loss Hub is still treating UK availability, approved indoor-unit combinations, MCS status, Boiler Upgrade Scheme treatment, installed cost and installer route as items to check before relying on the product for a quote, grant application or installation decision.
Do not assume the Samsung EHS Quint is MCS certified, BUS eligible, generally available or priced unless current official sources confirm the exact model and configuration.
The model references we checked against are the three Samsung currently publishes for the outdoor unit:
| Model reference | Capacity | Electrical supply |
|---|---|---|
| AE125HCTPESEU | 12.5 kW | Single phase |
| AE160HCTPESEU | 16.0 kW | Single phase |
| AE125HCTPGSEU | 12.5 kW | Three phase |
This page is a tracker. It reflects what we could establish on the date above, and it will be updated when that changes. The wider picture sits on the Samsung EHS Quint hub.
CONSIDERING HEATING AND COOLING TOGETHER?
Before committing to one system or two, find out what your home actually needs.
Product certification and installer certification are not the same thing
This is the most common misunderstanding I run into, and it costs people money.
MCS does two separate jobs. It certifies products, and it separately certifies installation companies. Different schemes, different assessments. A product being certified tells you nothing about the contractor standing in your kitchen.
Product certification means a specific piece of equipment has been assessed against the relevant MCS product standard and appears in the MCS Product Directory. It is granted to a model reference, not to a brand and not to a marketing name. A manufacturer can have twenty listed heat pumps and one unlisted new one, and the unlisted one still sits under the same logo in the same brochure.
Installer certification means a company has been assessed against the relevant MCS installation standard and holds certification for the specific technology it is installing. A firm certified for air source heat pumps is not automatically certified for everything else it might sell you. Certification belongs to the company rather than the individual with the van, and it can lapse.
For a grant-eligible installation you need both. A certified product installed by an uncertified company does not qualify. A certified company installing an uncertified product does not qualify either. Both halves have to be true on the day the work is done, which is why “they’re MCS” is not an answer to any question worth asking.
The Quint adds a wrinkle. Samsung presents it as doing air-to-water heating, domestic hot water and air-to-air heating and cooling from one outdoor unit. Those have historically been separate disciplines and, frankly, separate trades. Plenty of good heat pump installers have never commissioned refrigerant pipework to wall-mounted indoor units. Plenty of good air conditioning engineers have never done a room-by-room heat loss calculation. Whoever installs a Quint needs to be competent and appropriately certified across whatever the finished system actually contains.
MCS and the Boiler Upgrade Scheme are not the same question
People treat MCS certification and Boiler Upgrade Scheme eligibility as one thing. They are not.
MCS is a route to BUS, not a synonym for it. Ofgem administers BUS and maintains its own product eligibility arrangements for the scheme. A product appearing in the MCS Product Directory and a product being eligible for a particular BUS grant are separate determinations, and at the time of writing we have not been able to confirm either for the Quint.
Then there is the classification problem, specific to this product and genuinely unresolved. BUS currently pays £7,500 towards an air source heat pump and £2,500 towards an air-to-air heat pump, with an additional £1,500 available until March 2027 for off-gas-grid properties running on oil or LPG. The Quint does both jobs from one outdoor unit. Which category an installation falls into is not something an installer can settle by assertion, and grants are not available for hybrid systems, which sharpens the question rather than softening it.
I would treat any quote that deducts a grant figure from a Quint installation before eligibility is confirmed as a red flag. Not dishonesty necessarily, but optimism you are being asked to underwrite.

What to ask before you commit
If someone is offering you a Quint, these are the questions. Short, specific, and all entirely reasonable.
- What is the exact outdoor model reference you are quoting? Not “the Samsung Quint”. The full reference, in writing, on the quotation.
- Is that exact reference listed in the MCS Product Directory today? Ask for the listing, then check it yourself at mcscertified.com. A range being certified does not mean every variant within it is.
- Is the full configuration covered? For a dual air-to-water and air-to-air system this is not just about the outdoor unit. Ask what indoor units, hydronic module and cylinder are included, and how the certified scope covers that combination.
- Is your company MCS registered for this technology, right now? Ask for the certificate and the certification body, then check the registration is current and covers the technology in question.
- Who is doing the refrigerant work, and who is doing the heating design? If those are different firms, ask who carries responsibility for the system as a whole.
- Will you confirm all of that in writing before I pay a deposit? This is the one that separates a serious contractor from a hopeful one.
- If MCS or BUS status changes before installation, what happens to my price? Get the answer now, not after the scaffolding is up.
If you want the wider version of this, the Samsung EHS Quint quote checklist covers what a complete quotation should contain and the warning signs that it is not one.
Frequently Asked Questions
Is the Samsung EHS Quint MCS certified?
At the time of writing we have not found a listing in the MCS Product Directory under the EHS Quint name or the published model references. Do not assume certification. Check the exact model reference you are being quoted against the current directory.
Where do I check MCS certification myself?
The MCS Product Directory at mcscertified.com is the public source for certified products, and MCS also publishes a way to check installation companies. Both are free and take a couple of minutes. Search by model reference, not by brand name.
My installer says Samsung is MCS certified. Is that enough?
No. Certification attaches to specific model references, not to manufacturers. That tells you nothing about whether this particular unit, in this particular configuration, is listed.
Does MCS product certification mean the Quint qualifies for the Boiler Upgrade Scheme?
No. MCS is a route into BUS, not the same as BUS eligibility. Ofgem maintains separate product eligibility arrangements for the scheme, and neither has been confirmed for the Quint at the time of writing.
Why is certification less straightforward for the Quint than for a normal heat pump?
Because it is not a normal heat pump. Samsung presents it as running air-to-water heating, hot water and air-to-air heating and cooling from one outdoor unit. Certification schemes are built around defined technology categories, and a product that spans two of them raises questions a single-purpose unit does not.
If the outdoor unit is listed, is the whole system covered?
Not necessarily. Ask what the listing covers and how it relates to the indoor units, hydronic module and cylinder in your quote. This is the sort of detail that gets glossed over verbally and then matters at grant application stage.
Can I install one without MCS certification?
You can install non-certified equipment, but without grant support and without the consumer protection MCS registration brings. Make that decision deliberately, with the cost in front of you.
When will this page be updated?
