Is the Samsung EHS Quint Eligible for the Boiler Upgrade Scheme?
Quick answer
Not confirmed. At the time of writing we cannot confirm the Samsung EHS Quint appears on Ofgem’s Product Eligibility List, and we have found no MCS Product Directory listing for it.
Underneath that sits a second, more interesting problem. Even if the Quint becomes eligible, it is not obvious which grant it would attract. The scheme pays £7,500 towards an air source heat pump and £2,500 towards an air-to-air heat pump, and the Quint is presented as doing both jobs from one outdoor unit. Nobody has publicly settled how that gets classified.
So if you are being offered a Quint with £7,500 already knocked off the price, read on before you sign anything.
Current BUS 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.
We track the related questions separately: MCS certification and UK availability.
Why the Quint creates a classification question
This is the part of the page worth your time.
The Boiler Upgrade Scheme does not pay a flat amount for “a heat pump”. It pays different amounts for different categories of technology, and those categories were drawn up around products that do one thing. An air source heat pump feeding radiators, underfloor heating and a cylinder sits in the £7,500 bracket. An air-to-air heat pump — air conditioning that can also heat — sits in the £2,500 bracket. Two numbers for two jobs.
The Quint is presented as doing both jobs from one outdoor unit and one refrigeration system — a hydronic indoor unit and a cylinder on the water side, air-to-air indoor units on the refrigerant side. Samsung’s own wording describes simultaneous heating and cooling across air-to-air and air-to-water applications while also producing domestic hot water.
Read the grant categories again with that in mind and the difficulty is obvious. Is a Quint installation an air-to-water heat pump with an air-to-air capability attached, in which case £7,500 is the natural reading? Is it an air-to-air system with a hydronic function, at £2,500? Or is it a third thing the categories were never drafted to describe?
There is a further wrinkle. Grants are not available for hybrid systems. That exclusion is aimed at heat pumps paired with a fossil-fuel boiler, which is not what a Quint is. But a blanket exclusion for one kind of combined system tells you the rules assume clean categories, and the Quint deliberately does not sit in one.
Let me be plain about the limits here. Heat Loss Hub cannot answer this, and it is not ours to answer. Only Ofgem, through the Product Eligibility List and the scheme rules, can determine how a dual-function unit is treated. Until the product appears there with a stated classification, everyone discussing it — me included — is reasoning from definitions rather than from a decision.
What I can tell you is what an honest answer sounds like: “I don’t know yet, here is who I’m asking, and I won’t put a grant figure in your quote until I have it in writing.” Anyone confidently telling you the Quint attracts £7,500 has either seen a confirmation the rest of the market has not — ask to see it — or is telling you what they think you want to hear. In eighteen years I have met far more of the second than the first.
The exposure is not theoretical. The gap between the two figures is £5,000, and if a quote assumes the larger grant while the application lands in the smaller category, that difference does not come out of the installer’s margin.
The grant categories
The current Boiler Upgrade Scheme amounts:
| Technology | Grant |
|---|---|
| Air source heat pump | £7,500 |
| Ground source heat pump | £7,500 |
| Biomass boiler | £5,000 |
| Air-to-air heat pump | £2,500 |
On top of those there is an off-gas-grid uplift: an additional £1,500 for an air source or ground source heat pump where the property uses oil or LPG and has no mains gas connection, available until March 2027.
That uplift is where the £9,000 figure you may have seen comes from. It is £7,500 plus £1,500, not a separate headline grant. If you are on mains gas, £9,000 is not a number that applies to you, whichever heat pump you choose.
Other conditions worth knowing:
- One grant per property. You do not get an air source grant and an air-to-air grant for the same home.
- Capacity limits. 45 kWth for an individual heat pump, 70 kWth for multiple heat pumps, 300 kWth for a shared ground loop. Not a constraint a typical house will meet.
- Hybrid systems are excluded, as is replacing existing low-carbon heating.
None of that tells you which row a Quint sits in. That is the point.
CONSIDERING HEATING AND COOLING TOGETHER?
Before committing to one system or two, find out what your home actually needs.
Product eligibility and installation eligibility are not the same thing
People talk about BUS eligibility as if it were a property of the equipment. It is not. Three things have to be true.
One: the product has to be eligible. It needs to be on Ofgem’s Product Eligibility List, for the specific model reference you are installing — not a similar model, not the family in general. We have not confirmed a listing for the EHS Quint.
Two: the installation has to meet the scheme’s requirements. The property, what is being replaced, the capacity limits, and the standards the system is designed and commissioned to. An eligible product installed badly attracts nothing.
Three: it has to be done by an MCS certified installer. They apply on your behalf; you do not apply yourself. Their certification has to cover the technology being installed, which is a live question for a product spanning two technology types. Product certification and installer certification are different things — see the MCS status page.
Miss any one and there is no grant. For a Quint, all three have open questions attached.
What to ask before you accept a quote
If someone quotes you for a Quint, put these to them in writing.
- Which BUS category are you claiming under, and on what basis? Not “it’s a heat pump, so £7,500” — which row of the table, and what confirms it.
- Is this exact model reference on Ofgem’s Product Eligibility List today? Ask them to send the listing, not a description.
- Does your MCS certification cover this installation? Including the air-to-air side, if indoor units are in the design.
- What happens if the application is refused, or approved at a lower amount? Put it in the contract. Does the price drop, do you pay the difference, or can you walk away?
- Never accept a quote with the grant already deducted unless eligibility is confirmed for your exact configuration. A quote showing “£X less £7,500 BUS grant” has settled a question on your behalf that is not settled.
- Get all of it in writing. Verbal reassurance about eligibility is worth nothing when the application is assessed.
If those questions make the conversation awkward, that tells you something about who you are dealing with.
Do the design work regardless. Heat loss, emitters and hot-water demand do not change with the product you choose or the grant it attracts — see the Samsung EHS Quint hub for where things stand, and the cost page for what drives the installed number.
Frequently Asked Questions
Can I get £7,500?
£7,500 is the current Boiler Upgrade Scheme amount for an air source heat pump. Whether a Quint would be treated that way is not confirmed, and nobody should be telling you it is until Ofgem’s position is clear.
Can I get £9,000?
£9,000 is £7,500 plus the £1,500 off-gas-grid uplift, which applies where the property uses oil or LPG and has no mains gas connection, and runs until March 2027. It is not a separate grant, and it depends on the £7,500 category applying — which for a Quint is unconfirmed.
Can I get £2,500 instead?
£2,500 is the current amount for an air-to-air heat pump. Because the Quint has an air-to-air capability, that category is part of the open question, not a fallback to rely on. It is not established that a Quint attracts £2,500 either.
What if the grant is refused after installation?
Protect yourself against that contractually, before work starts. If your quote had a grant deducted and the application fails, you need to know who carries the cost. Agree it in writing, and treat reluctance as a reason to pause.
Does the Quint count as a hybrid system?
The scheme excludes hybrids, which in BUS terms means a heat pump combined with a fossil-fuel boiler. A Quint is not that. But it is a combined system in a scheme built around single-technology categories, which is why the classification needs confirming rather than assuming.
Is the Samsung EHS Quint MCS certified?
Not as far as we can find. MCS certification is a prerequisite for the grant, so that question has to be settled before this one can be.
Should I wait for it if the grant position is unclear?
If your heating has failed or you are working to a fixed date, waiting on an unconfirmed grant position for an unconfirmed product is not a plan. If you have time, watch the status — but get the design done now, because it holds whichever product you choose. See the UK availability tracker and the Samsung EHS Quint hub.
