REFCOM Elite rewards businesses whose systems produce traceable evidence. Prepare by mapping the credential layers, auditing your job records against a rubric, practising CO2e calculations and flammable-refrigerant paper scenarios, and rehearsing what a complete, defensible record looks like.
Why company systems, not personal technique, sit at the centre of Elite
REFCOM Elite is a certification for businesses, assessed on the systems a company runs — records, procedures and competence evidence — rather than on one individual's hands-on refrigerant handling skill.
REFCOM operates the UK's F-Gas certification register for companies and engineers, and Elite is an additional tier for certified businesses, including Elite Supplier businesses. Because the unit being certified is the company, the substance of the standard lives in whether documented processes exist, are followed consistently, and can be shown to an assessor when asked.
The practical consequence for preparation is a shift of focus. Revising vapour-compression theory or recovery technique helps individual engineers, but it does not build the thing Elite examines. Build an evidence map instead: where leak-check records live, which template a service visit uses, how the F-Gas software or log book links a job to an asset, and who can produce each document on request. Treat every gap in that map as a study objective.
Telling apart company registration, Elite status and individual F-Gas categories
Three layers are easy to conflate: company F-Gas registration, the Elite tier for companies and suppliers, and the individual engineer categories. Each is held by a different entity and demonstrates something different.
Company registration on an F-Gas register shows the business is certified to employ or engage appropriately qualified staff for regulated refrigerant activities. Elite is a further company-level designation REFCOM offers on top of registration, with its own application and renewal process, and a separate Elite Supplier route for supply-chain businesses. Neither replaces the personal qualification an engineer holds.
Individual competence is handled through engineer categories, such as Category 1. REFCOM's public guidance addresses which personnel categories are required for specific regulated activities, including SRAC decommissioning — but the exact wording of that requirement matters, and you should verify it against the current guidance on REFCOM's site before relying on it in a compliance argument or a job allocation. A frequent preparation error is treating a senior engineer's personal category as if it satisfied the company-level requirement, or assuming Elite covers the personal category. Keep the three layers separate in your notes. Use the table below as a one-glance decision aid when you are unsure which requirement a task triggers.
| Layer | Who holds it | What it demonstrates | Evidence focus |
|---|---|---|---|
| Company F-Gas registration | The business | Company certified under the F-Gas scheme | Registered status, certified staff engaged |
| REFCOM Elite (company) | Certified businesses | Enhanced company-level standing under REFCOM | Systems, records, procedures, surveillance readiness |
| REFCOM Elite Supplier | Supply-chain businesses | Elite designation for supplier businesses | Supplier-specific criteria under the Elite scheme |
| Individual F-Gas category | Each engineer | Personal competence for defined activities | Category certificate, scope of permitted work |
Building a leak-check and record trail that survives scrutiny
A record is only useful if another person can reconstruct what was checked, on which asset, with which refrigerant, by whom, and what happens next. Vague entries fail that reconstruction test.
Scenario: an engineer completes a periodic leak check on a roof-mounted chiller and the log entry reads 'Leak check carried out, no leaks found, signed J.S.'. The plausible mistake here is treating the entry as finished work. It names no asset or circuit, no refrigerant type or charge, no CO2-equivalent basis, and no date for the next action. Two years later, nobody can prove which system was checked or that the check applied to the right equipment at all.
The better decision is to write the entry against the company template so it records the asset identifier and circuit, refrigerant and charge, the CO2-equivalent figure where relevant, the date, the checker and their category, the outcome, and the next scheduled action. Why it matters: under a scheme with surveillance and enforcement, an incomplete trail is indistinguishable from no trail. The company-level argument — 'our process produces this record every time' — only holds if the record actually carries those fields.
Working confidently with CO2-equivalent figures on the job sheet
CO2-equivalent is charge multiplied by global warming potential. Practising the calculation on real nameplate figures turns an abstract phrase into a tool for classifying plant and framing obligations.
Worked example, using illustrative GWP values for training purposes: a system holds 7.5 kg of R-410A. Taking an illustrative GWP of about 2,088, the charge equates to roughly 7.5 × 2,088 ÷ 1,000 = 15.7 tonnes of CO2-equivalent. The same 7.5 kg of R-32, with an illustrative GWP of about 675, equates to roughly 5.1 tonnes. Note that the exact GWP value depends on which IPCC reference set the applicable rules specify, so confirm the correct value before relying on the result for any formal determination.
Apply the habit in three places: when classifying plant so the right activities and records attach to it; when checking supplier or commissioning paperwork for consistency between the stated refrigerant, charge and CO2e figure; and when writing job records so the CO2e basis is stated rather than implied. A self-check: pick three nameplates on real or sample systems, run the arithmetic, and confirm your figure and the paperwork's figure agree — or that you can explain the difference.
Flammable refrigerants: what changes in procedure and paperwork
A refrigerant's flammability classification changes equipment choice, ventilation and ignition control on site, and it changes who may perform certain activities and what the record must show.
Conceptually, flammable classifications sit on the refrigerant, not the job. When the refrigerant is flammable, the plan must account for it: recovery and charging equipment compatible with that refrigerant, appropriate ventilation, control of ignition sources, and staff trained for the work — REFCOM promotes a dedicated 'Working with Flammable Refrigerants' course, which signals that this competence is treated as distinct. The paperwork then has to evidence those decisions, not just the outcome.
Scenario: a job sheet is drafted to recover refrigerant from a small split system labelled R-32, a lower-flammability refrigerant. The plausible mistake is writing it as a routine recovery with no reference to flammability, using the default recovery setup, and allocating it without checking which personnel categories REFCOM's guidance requires for that activity. The better decision: the job sheet flags the classification, specifies compatible recovery equipment and cylinder, notes ventilation and ignition checks, and allocates the work only after confirming, against the current official guidance, the category held by the allocated technician. Why it matters: the record then demonstrates both safe practice and traceable competence, which is exactly the kind of chain a company-level assessment asks you to produce.
Calibration, log books and templates: converting tools into evidence
Calibrated scales, standard log books and consistent templates only become evidence when each document links to the others. Audit that linkage deliberately rather than assuming it exists.
REFCOM membership benefits include a free weighing-scales calibration checking service and free log book and templates such as service and commissioning sheets. That matters because a recorded charge is only trustworthy if the scales behind it are checked and traceable. Calibration certificates, completed log books and a consistent template set form one connected chain: measurement, record, and the form that standardises both.
Practical exercise with expected observations: pull three recent job records from your own or a sample business. For each, check six things — asset identifier; refrigerant type and recorded charge; date and nature of the activity; engineer name and category; next action and due date; and evidence that the scales used were within calibration. Expected observation: gaps cluster around the next-action date and the calibration link, and the charge often cannot be traced back to a checked instrument. Score each record out of six; treat the score as a learning milestone, not a pass prediction. If any record scores four or fewer, the fix is a template and process change, not more revision.
An audit-first preparation sequence and readiness checks
Sequence your preparation as an audit project: map the credential layers, gather and grade your documents, rehearse paper scenarios, then close the gaps you found before any assessment conversation.
A realistic adaptable sequence: in the first phase, write one-sentence definitions of company registration, Elite, Elite Supplier and individual categories, and list which staff hold which category. In the second, assemble log books, templates, calibration evidence and training records, then grade sample records with the six-point rubric above. In the final phase, run paper scenarios — an ambiguous log entry, a flammable-refrigerant decommissioning sheet, a CO2e calculation — and rewrite each one until it passes your own rubric.

Readiness checks before you call preparation complete: you can state in one sentence who holds each credential layer; you can compute a CO2-equivalent figure from a nameplate and name the assumption in your GWP value; you can list the fields a compliant job record must carry without looking; and you can point to the current REFCOM guidance wording on which personnel categories may perform SRAC decommissioning, verified against the source rather than recalled from memory. When those four answers come without hesitation, your systems — not just your memory — are the thing you have studied.
