IE F-Gas Category IV

It covers basic handling of fluorinated greenhouse gases - chiefly recovering refrigerant from small stationary equipment, leak checking and record keeping. It does not by itself authorise installation, commissioning or the more complex servicing reserved for higher categories. Check the current scope with the awarding body and your employer before taking on work.

Assessment is typically multiple choice, often combined with a short practical element on recovery equipment. The awarding body publishes the current structure, number of questions and time allowed on its website; confirm there rather than relying on course-provider summaries, which can lag behind programme changes.

Most candidates find the environmental and legal questions straightforward if they have read the regulation summaries, while leak-rate calculations, cylinder identification and recovery procedure steps catch people out. It rewards careful reading rather than deep engineering knowledge, so a structured few weeks of study is usually enough.

Retake arrangements are set by the awarding body and the training provider, and can include a waiting period or a fee for reassessment. Because these rules change, check the current retake policy directly with the body that issues the certificate before you book a first attempt.

A common pattern is a short taught course of a few days plus two to four weeks of revision at home. Spend most of that time on the domains you find weakest, and make sure you can explain leak checking, recovery and record keeping in your own words rather than memorising lists.

Start with environmental impact and the legal framework so the later rules make sense, then refrigerant properties and safe handling, then leak checking and records. Recovery and disposal follows naturally, and health and safety is best revisited last as a consolidation pass across everything else.

Three recurring problems: confusing GWP values or refrigerant designations, muddling the leak-check frequency thresholds, and skipping the practical logic of recovery - purging, vacuum and cylinder safety. Another is underestimating record keeping, which is examined as a legal duty rather than paperwork.

No. Category IV is designed as an entry point, so the course assumes little prior refrigerant knowledge. Some familiarity with basic tools and safe workshop practice helps, but the syllabus teaches the environmental, legal and handling content from first principles.

Those details are published by the awarding body and vary by provider and date. This page deliberately does not quote figures because they change. Check the awarding body's own website and your chosen training provider for the current fee, schedule and pass mark before committing.
