Describe what each inspection point is looking for and the pass/fail threshold
Explain how to record and escalate defects found during service
Differentiate routine maintenance from safety-critical inspection tasks
Your checkpoint

Fault Diagnosis and Repair
Apply a structured fault-finding sequence from symptom to verified cause
Diagnose common combustion, ignition, and gas-supply faults from described symptoms
Distinguish repair options and justify when to repair vs. isolate
Explain how to verify a repair before returning an appliance to service

Safety and Regulatory Requirements & Gas Characteristics, Combustion, and Ventilation & Pipework, Fittings, and Jointing & Installation, Commissioning, and Testing & Service, Maintenance, and Inspection & Fault Diagnosis and Repair & Emergency Procedures and Unsafe Situations
Complete a timed mixed-domain mock assessment and score it by domain
Re-study the two weakest domains using targeted drills
Re-verify the reference sheets and checklists built in earlier weeks
Consolidate a final revision sheet of facts you repeatedly missed
Your checkpoint
A scored mock assessment with a written remediation plan for weak domains
Milestones
Week 2: Score 80% or higher on a 20-question self-test covering domains 1 and 2
Week 4: Commissioning and tightness-test checklist reviewed against regulation notes with no gaps flagged
Week 6: Diagnose at least 10 of 12 fault scenarios to a verified cause without prompts
Week 8: Score 75% or higher overall on the timed mock, with no domain below 60%
