An MCS umbrella scheme lets you carry out MCS-certified heat pump installs under another company's accreditation, instead of holding your own. The umbrella company is the certified body of record: it takes on the system-design review, the compliant sign-off and the grant paperwork, while you do the install on the tools.
For a lot of experienced heating engineers, that's the difference between watching the heat pump work go elsewhere and taking it on. Your own MCS certification is a real commitment of time and money, and it doesn't make sense for every business at every stage. An umbrella scheme is a way in without that commitment.
Here's how it works, what it covers, and what separates a good scheme from an expensive one.
The short answer
An MCS umbrella scheme is an arrangement where an MCS-certified company lets you install heat pumps under its accreditation. You handle the installation; the umbrella provider handles the certification, the compliant handover and the Boiler Upgrade Scheme (BUS) grant paperwork. It means you can offer grant-eligible heat pump installs — and take on that work — without being MCS certified yourself, though many already-certified installers use one too, purely to offload the admin.
Why does MCS certification matter for heat pump work?
Because without it, the grant is off the table. To claim the £7,500 Boiler Upgrade Scheme grant on a heat pump in England and Wales, the install has to be done by an MCS-certified installer. That isn't a nice-to-have — from 28 April 2026, the Boiler Upgrade Scheme regulations formally tie the installer definition to MCS certification, and non-certified installers can't apply for the grant, whatever the quality of the work.
That grant is what makes most heat pump jobs affordable for the homeowner, so in practice MCS certification is the gate to the work. The same 2026 changes also removed the EPC requirement, extended the scheme to 2030, and brought air-to-air heat pumps in at £2,500 — so the pipeline of grant-backed work is set to keep running for years. And from 21 July 2026, off-gas-grid homes replacing oil or LPG can claim an uplifted £9,000, which puts heat pump conversions well within reach for a lot of rural households.
Getting your own MCS certification is one route through that gate. An umbrella scheme is the other.
How does an MCS umbrella scheme work?
The umbrella provider is the certified entity, so the compliance sits with them, not you. A typical job runs like this:
You submit the job. You pass the property and system details to the umbrella provider, usually with your own design and quote.
The design gets a compliance check. The provider reviews the system design against MCS standards — a second pair of eyes, not a takeover of your work.
You install. You carry out the installation, the part you already do well.
The provider certifies and signs off. They commission to MCS standards, issue the MCS certificate for the install, and produce the compliant handover pack.
The grant paperwork is handled. The provider submits the BUS application and manages the redemption, so the grant flows through without you chasing it.
The exact shape varies by provider — some include site visits, some lean more on remote review — but the principle is constant: their accreditation, their sign-off, your install.
Do I need my own MCS certification to install heat pumps?
No — not if you work under an umbrella. Whether or not you already hold MCS certification, an umbrella scheme lets the install be certified under the provider's accreditation. Every install is certified; the question is only whose accreditation carries it.
That flexibility cuts both ways. If you're a gas or oil engineer moving into heat pumps, an umbrella means you can take on grant-eligible work now, while you decide whether your own certification is worth it later. If you're already MCS certified, you can still put jobs through an umbrella to offload the admin, the design review and the compliance load — keeping your own certification for the work where it earns its keep.
Worth being clear on one thing: an umbrella scheme is not a shortcut to becoming certified yourself. It doesn't train or accredit you. It gives you a compliant, grant-eligible route to the work under someone else's accreditation — which for a lot of installers is exactly what's needed, and for others is a stepping stone.
What does an MCS umbrella scheme usually cover?
The admin around a heat pump install can swallow the best part of a day per job — the certification, the notifications, the handover, the grant claim. A good umbrella takes most of that off your desk. Typically that means:
MCS certification and commissioning of the install
The compliant handover pack the homeowner needs
BUS grant application and redemption
DNO (grid) notifications where the install needs them
A design review against MCS standards
Technical support when a job throws up something unusual
The more of that a scheme handles end to end, the more time you get back for the work that pays.
What should you look for in an MCS umbrella scheme?
Not all umbrellas are built the same, and the differences show up in the cost and the small print. A few things worth weighing before you commit:
The cost, and how it's charged. Some schemes charge a monthly or annual membership; some charge per install; some do both. For an installer just starting out with heat pumps, a standing membership can bite before the work has built up. Look for pricing that only costs you when you're actually doing a job.
Lock-in. Some schemes tie you in with minimums or notice periods. If you'd rather use an umbrella on the jobs that suit and walk away when they don't, check you're free to.
Whose design is it. A review against MCS standards is a genuine safeguard. A provider taking your design off you and replacing it is a different thing. If you want to keep designing the systems you install, make sure the scheme is set up as a check, not a takeover.
What happens after handover. Aftercare has a habit of landing back on the installer months later. A scheme with monitoring and a support team behind it means questions and early issues don't automatically come back to you.
How Ample fits in
Ample runs a full MCS umbrella, and every install done through Ample is certified under our accreditation — whether or not you hold your own. There's no membership and no tie-in: a flat per-project fee (currently £210, passed through at cost) covers the regulatory essentials, and there's nothing to pay until the job's done. See how Ample's MCS umbrella works.
We handle the BUS applications and redemption, the DNO notifications, the Insurance-Backed Guarantee and the compliant handovers on every job. Your system design stays yours — our review is there as a backup, not a takeover. And once you've left site, our team and monitoring stay with you and the homeowner, so aftercare doesn't come back to you. There's also finance built into the quote by Ample and, separately, payment on each confirmed milestone within one working day — so cashflow keeps up with the work.
Frequently asked questions
What is an MCS umbrella scheme? It's an arrangement where an MCS-certified company lets you install heat pumps under its accreditation. You do the install; the umbrella provider handles the certification, the compliant handover and the Boiler Upgrade Scheme paperwork. It means grant-eligible heat pump work is open to you without holding your own MCS certification.
Do I need to be MCS certified to install heat pumps under the Boiler Upgrade Scheme? The install does. From 28 April 2026, the Boiler Upgrade Scheme ties the installer definition to MCS certification, and only MCS-certified installs can claim the grant. Under an umbrella scheme, the install is certified under the provider's accreditation — so the work qualifies without you being certified yourself.
How much is the Boiler Upgrade Scheme grant? £7,500 towards an air source or ground source heat pump in England and Wales. From 21 July 2026, off-gas-grid homes replacing oil or LPG can claim an uplifted £9,000 (to 31 March 2027). Air-to-air heat pumps became eligible at £2,500 from 28 April 2026. Confirm current values on GOV.UK before quoting them to a homeowner.
Does an umbrella scheme get me MCS certified? No. An umbrella scheme lets you work under another company's accreditation; it doesn't train or accredit you. It's a compliant, grant-eligible route to the work — useful whether you're moving into heat pumps or already certified and just offloading the admin.
Can I use an umbrella scheme if I'm already MCS certified? Yes. Plenty of certified installers put jobs through an umbrella to hand off the design review, the compliance and the grant paperwork, and keep their own certification for the jobs where it earns its keep.
What does an MCS umbrella scheme cost? It varies. Some charge a monthly or annual membership, some charge per install, some both. Watch for standing charges that bite before the work builds up, and for lock-in. Ample charges a flat per-project fee at cost, with no membership and nothing to pay until the job's done. (Fee figures gated — confirm current pricing before publish.)
