Compliance
F-Gas compliance in the UK: a practical 2026 checklist
Engineer certification, leak-test intervals, refrigerant logs and what the EA actually asks for during an audit.
Who needs to be certified
Anyone installing, servicing, maintaining, repairing, decommissioning or leak-checking stationary refrigeration, AC or heat pump equipment containing F-gas needs a Category I–IV certificate appropriate to the work. The company also needs a company certificate.
Leak-test intervals at a glance
5–50 t CO2e: every 12 months. 50–500 t CO2e: every 6 months (or 12 with a leak detection system). >500 t CO2e: every 3 months (or 6 with leak detection). Record every test against the equipment record.
What auditors actually ask for
An equipment register with refrigerant type and charge, a leak-test history per unit, refrigerant added/recovered logs with engineer name and cert number, and your company F-Gas certificate. Work App generates all of this automatically from service reports.
Key takeaways
- Tie every refrigerant entry to a certified engineer
- Automate interval reminders by charge size
- Keep photos on the equipment record, not in inboxes
