The MCS quality management system
A quality management system is the set of documented processes and controls that show how your business consistently produces compliant installations. For MCS it is the bulk of what gets assessed, and the single thing that most often sends an application back. The test an assessor applies is not whether the document is impressive - it is whether the job file in front of them matches what the document says you do.
What it is for
MCS defines a QMS as a set of processes and controls designed to help a business deliver a high-quality service and manage its operations. That is deliberately unglamorous. It is not a certification in its own right and it is not ISO 9001 - it is the written version of how you actually work, sized to how complex your MCS work is.
The reason it dominates the assessment is that it is the only thing an assessor can check against evidence. A claim about your standards is unfalsifiable. A procedure that says every installation gets a commissioning record, checked against a job file with no commissioning record, is not.
What it has to cover
The scope follows the job from enquiry to aftercare. In practice an assessor will want to see the documented process and then a real example of each of these.
- Design and system sizing - how a heat loss calculation gets done, by whom, and where it is filed.
- Pre-sale information and the performance estimate - what the customer receives before they sign, and how you know they received it.
- The contract and consumer code obligations - cancellation rights, deposit protection, and the timescales your code requires.
- Installation and supervision - who signs off compliance, and how that is recorded.
- Commissioning and handover - the records, the documentation pack, and the customer demonstration.
- Complaints - a log, response timescales, and escalation to your consumer code.
- Records and document control - versions, who can change a template, and how long you keep job files.
- Training and competence - certificates for the people doing the work, and when they were renewed.
- Suppliers and equipment - who you buy from, and calibration records for anything that measures.
Free templates, or software
MCS publishes QMS templates free, for guidance rather than as a requirement: a documented procedure manual for a company, a separate one for a sole trader, plus document data control, an equipment log, training records, suppliers, an index of contracts and a complaints log. You do not have to use them, and you do not have to use anything else either.
QMS software - typically around £750 a year - is not buying compliance. It is buying the discipline: a job cannot be marked complete without the record attached, so the gap between what you wrote and what you did closes automatically. If your records currently live in a van, that is worth paying for. If you are meticulous and low-volume, the free templates plus a folder structure genuinely pass.
The version that fails is neither: a downloaded manual describing a business that is not yours, kept because it looked official.
The non-conformities that come up most
They are boringly consistent, and almost all of them are the same failure in different clothes - the document and the evidence do not match.
- A procedure describing a step nobody actually performs, or a role nobody actually holds.
- Job files missing one document the procedure says is mandatory - usually the commissioning record or the handover sign-off.
- A complaints log that is empty because complaints were handled by phone and never written down.
- Training records that have expired, or that cover a person who has left.
- Uncontrolled documents - two versions of the same form in use, with no way to tell which is current.
- A heat loss calculation that cannot be traced back to the system that was actually installed.
Write it after you have done a job, not before
The fastest route to a QMS that survives an assessment is to complete one compliant installation, keep every scrap of paper it generated, and then write the procedures to describe what you did. You need a compliant installation for the assessment anyway.
Written that way round, the evidence exists before the claim does, which is the opposite of how most failed applications are put together.
Common questions
Do I need a quality management system for MCS?+
Yes. Documented processes and controls appropriate to the size and complexity of your MCS work are a Scheme requirement, and they are the bulk of what your certification body assesses.
Does the MCS QMS have to be ISO 9001?+
No. ISO 9001 is a separate certification and is not required. What MCS asks for is a documented system that matches how your business actually operates.
Are there free MCS QMS templates?+
Yes - MCS publishes them, including a procedure manual for companies and a separate one for sole traders, plus logs for complaints, equipment, training, suppliers and contracts. They are guidance, not mandatory.
Is QMS software worth paying for?+
It is worth it when it stops records being forgotten - when a job cannot be closed without its paperwork attached. At low volume with disciplined filing, the free templates pass an assessment perfectly well.
What is the most common MCS non-conformity?+
A gap between the written procedure and the job file - the document says a step happens and the evidence for that step is missing. Almost every common finding is a version of that.
