The visit, step by step
Asset check
We record each system's refrigerant type and charge and calculate its CO2e.
Set the frequency
Each system gets the legal interval for its CO2e and any automatic leak detection.
Check
The engineer checks joints, valves, components and operating data for signs of leakage.
Record
Results are recorded and kept on your F-gas log for at least five years.
Local points to consider
Operator duty
The legal duty sits with the operator — the person or business with actual control over the equipment.
Shared buildings
In multi-let buildings, roof space, risers and plant areas are often controlled by a managing agent. We work to their permits and method-statement requirements.
Certified engineers
Leak checks must be done by an engineer holding the right F-gas certification.
Neighbours and noise
Outdoor units near flats — common above shops — need careful siting so noise at neighbours' windows stays low. We choose positions and quieter units with that in mind.
Who we work with in Hatfield
- Hotels and hospitality: quiet bedroom units, public-area cooling and heat recovery for hotels.
Compliance in England: refrigerant work falls under GB F-gas rules, and buildings with more than 12 kW of air conditioning in total need a periodic energy inspection (often called TM44).
