Refrigerant leak checks, TM44 inspections and HVAC servicing in one register.
Track F-Gas leak checks, refrigerant logs and air-conditioning inspections (TM44) with automatic recurring schedules.
The duty
What HVAC & Refrigeration compliance involves.
The F-Gas Regulation requires operators of stationary refrigeration and air-conditioning equipment to prevent leaks, carry out regular leak checks based on CO₂-equivalent charge, and keep records for each system.
CertFlow tracks refrigerant charge per system, sets leak-check frequency automatically, and keeps the logs and TM44 inspection reports audit-ready.
Your legal duties
What the regulations require.
Leak prevention and checks
Operators of stationary refrigeration and air-conditioning equipment must prevent leaks and carry out regular leak checks, with the frequency set by the CO2-equivalent charge of each system.
Record keeping
Records must be kept for each system covering the refrigerant type and quantity, the dates and results of leak checks, refrigerant added or recovered, and the certified company or technician who did the work.
Certified personnel and recovery
Work on F-Gas systems must be carried out by certified personnel, and refrigerant must be recovered for recycling, reclamation or destruction at the end of the system life.
Air-conditioning inspection (TM44)
Air-conditioning systems above the relevant output must be inspected by an accredited energy assessor under TM44, at intervals not exceeding five years, producing an inspection report.
How CertFlow handles it
From due date to defensible certificate.
HVAC & Refrigeration runs on the same platform as every other discipline, so the workflow, the registry and the audit trail are identical, whatever your team inspects.
Ready-to-issue templates
A built-in F-Gas Regulation report template, plus a drag-and-drop builder and bespoke PDF overlay for any client-specific form.
Automatic scheduling
Put every hvac & refrigeration asset on a recurring examination cycle. CertFlow generates the jobs and warns you before anything falls due.
Captured on site, offline
Readings, photos and signatures are captured in the field on mobile, fully offline, and sync the moment a connection returns.
Audit-ready proof
Every hvac & refrigeration certificate is filed in a searchable, exportable compliance registry with a full timestamped history.
From the field
What inspectors commonly find.
The defects and gaps that come up again and again on hvac & refrigeration inspections, the ones a good system helps you catch before an auditor does.
- Leak checks not carried out at the frequency the CO2-equivalent charge demands
- Refrigerant logs incomplete, missing or not reconciled
- Work or refrigerant recovery done by non-F-Gas-certified personnel
- TM44 air-conditioning energy inspections overdue
- Recovered refrigerant not properly accounted for at end of life
Why it matters
Penalties & enforcement.
F-Gas breaches are enforced by the Environment Agency and can bring civil penalties, and missing TM44 inspections carry their own penalties. Poor refrigerant management also means lost gas, higher running costs and avoidable environmental harm.

HVAC & Refrigeration on CertFlow, answered.
How often are F-Gas leak checks required?
Frequency depends on the CO2-equivalent charge of the system: broadly at least every 12 months for systems of 5 tonnes CO2e or more, more often for larger charges, with a fixed leak-detection system reducing the required frequency.
What records must be kept for F-Gas?
For each system: the refrigerant type and quantity, the dates and results of leak checks, the quantities added or recovered, and the details of the certified company or technician.
What is a TM44 inspection?
A statutory energy inspection of air-conditioning systems above 12 kW by an accredited assessor, at intervals not exceeding five years, which produces a report with recommendations to improve efficiency.
How does CertFlow help with F-Gas?
CertFlow tracks the refrigerant charge per system, sets the leak-check frequency automatically from the CO2e charge, and keeps the logs and TM44 reports audit-ready.
Can CertFlow manage refrigerant inventory?
Yes. Each system holds its refrigerant type, charge and movement history, which supports both leak-check scheduling and the reporting obligations.
