What is the passing score for the C&G 2079-11 F-Gas Category I exam?

The public City & Guilds 2079-101 specification grades the assessment Pass/Fail but does not publish a numeric cut score. Candidates must pass both the 40-question online test and the practical assignment; confirm current reassessment rules with the approved centre.

Who should take the F-Gas Category I (2079) qualification?

It is designed for experienced refrigeration, air-conditioning and heat-pump workers who need Category I scope. Before booking, confirm where the work will occur because Great Britain, Northern Ireland, and EU recognition rules are not interchangeable.

How long is the F-Gas Category I exam?

The theory exam is 40 on-screen multiple-choice questions answered within 80 minutes as a closed-book assessment, alongside a separate practical. Our 100-question practice bank helps you confirm mastery first.

What does the F-Gas Category I certificate qualify me to do?

Category I is the broadest activity category for leak checking, recovery, installation, servicing and maintenance on stationary RACHP systems, but territorial recognition, employer authorisation, other safety competence, and company certification can still apply.

Is this free F-Gas Category I practice test comprehensive?

Yes, it includes 100 research-based practice questions across all 2079 content areas with detailed explanations for every answer, plus a free AI tutor. All content is free forever, updated for 2026.
