What MCS certification costs
There is no single price for MCS certification, because nobody sells it as one thing. You pay a certification body, a consumer code, a quality-management-system provider, an insurer and Companies House separately, and each sets its own fee. For a one-person ASHP business starting from nothing, a realistic first year is around £2,800 to £3,200 including VAT - of which roughly £220 is one-off and the rest recurs every year.
You are not buying one product
The most common reason installers are shocked by the bill is that they budget for "MCS" as one line and then meet four more. MCS itself does not assess you and does not take most of the money. Your certification body does the assessing and charges for it. A consumer code charges you to join and again every year. A quality management system has to exist, and for most people that means paying for software. You need insurance that covers design as well as installation. If you are not already trading through a company, that is another registration.
Everything below is a fee paid to an external body. None of it is a passrpl fee and we do not receive any part of it.
The line items
These are indicative figures including VAT for a small ASHP installer in England, and every one is set by the provider rather than by us. Treat them as a budgeting baseline and confirm each with the provider before you commit.
- Company setup - about £100, one-off, if you are incorporating rather than trading as a sole trader.
- Public liability and professional indemnity insurance - roughly £500 to £900 a year. It varies with cover level, turnover and claims history more than anything else on this list. You need professional indemnity as well as public liability, because under MCS you are designing the system, not only fitting it.
- Quality management system software - around £750 a year. You can build a QMS from the free templates MCS publishes instead, which costs nothing but your time.
- Consumer code joining fee - about £120, one-off.
- Consumer code membership - about £360 a year.
- MCS registration and certification body fees - around £1,000 a year for a single technology.
- Website - varies with what you need, and the Scheme checks do look at how your business appears online.
One-off against every year
Splitting the list that way is what makes it plannable. The one-off element is small: company setup and the consumer code joining fee, roughly £220 together. The recurring element is the real cost of being certified - insurance, QMS, consumer code membership and MCS registration - which lands somewhere around £2,600 to £3,000 a year.
That makes a first year of roughly £2,825 to £3,225, and every year after that roughly £2,600 to £3,000. Certification is a subscription, not a purchase, and an installer who budgets only for year one is the installer who lets it lapse in year two.
What the list does not include
Your qualifications are separate and come first. The Level 3 air source heat pump units, and low temperature heating and hot water system design, are training costs paid to a training provider before any of this starts. The recognition of prior learning route exists precisely because sitting a full course is the more expensive way there for someone who already has the trade behind them.
Your first compliant installation is also not on the list, and it is not optional: your certification body assesses you against a real, completed job for each technology you want certifying. Registering each completed installation afterwards carries its own fee - ask your certification body for the current figure, because it is charged per installation rather than per year.
The largest uncosted item is your own time. Writing a quality management system that matches how you actually work, gathering evidence, and reworking whatever the assessor raises as a non-conformity is measured in weeks, not hours.
Where the money gets wasted
The expensive mistakes are almost always sequencing mistakes. Paying a year of QMS software before there is a company to run it in. Joining a consumer code before deciding which certification body you are applying to. Booking an assessment before you have an installation the assessor can actually look at. None of that is refundable, and the calendar cost is worse than the cash cost - a stalled application still burns the annual fees you have already paid.
The other avoidable cost is the second attempt. Non-conformities found at assessment have to be answered with a root cause and a correction before your certification body will close them, and an application that loops back through that has spent money on nothing.
Funding, if you are in Scotland
MCS runs a certification fund that covers part of the certification fee for small and medium businesses with a registered office in Scotland, aimed at heat pump certification. It does not apply to businesses registered in England, Wales or Northern Ireland. Check the current terms and the money available directly with MCS before building it into a budget - a fund is not a rate.
Common questions
How much does MCS certification cost in total?+
For a small ASHP installer in England, budget roughly £2,800 to £3,200 including VAT for the first year, and roughly £2,600 to £3,000 for each year after. That covers company setup, insurance, QMS software, consumer code and MCS registration. It excludes your qualifications and your own time.
Do I pay MCS directly?+
Only in part. You apply to a certification body, which sets its own fees and does the assessing; MCS runs the Scheme checks and issues the Installer Agreement. Your consumer code, your QMS provider and your insurer bill you separately. There is no single invoice.
Is MCS certification a one-off cost?+
No. Most of it recurs annually - insurance, consumer code membership, QMS and certification body fees - and you are audited again after the first year. Only company setup and the consumer code joining fee are genuinely one-off.
Is there VAT on it?+
The figures above include VAT. Some providers quote excluding VAT, which is how a quote that looked lower turns out not to be. Check which basis you are being quoted on before comparing two of them.
Is an umbrella scheme cheaper than getting MCS certified?+
It avoids the certification costs entirely, because you work under somebody else’s certification. You pay for that in margin and in not owning the customer. Whether it is cheaper depends on how many installations a year you do - past a certain volume, your own certification costs less than the share you are giving away.
