How we handle F-gas leak checks in Hertfordshire
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.
Things to check in Hertfordshire
Operator duty
The legal duty sits with the operator — the person or business with actual control over the equipment.
Access and parking
Town-centre jobs in Hertfordshire often come down to access — loading restrictions, parking for the van and getting equipment onto a roof. We check this at survey and plan deliveries around it.
Certified engineers
Leak checks must be done by an engineer holding the right F-gas certification.
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.
Typical premises in Hertfordshire
- Hotels and hospitality: quiet bedroom units, public-area cooling and heat recovery for hotels.
In England, systems holding 5 tonnes CO2 equivalent of refrigerant or more fall under GB F-gas rules, with regular leak checks and records; buildings with more than 12 kW of air conditioning in total also need a periodic energy inspection.

In Great Britain, equipment containing F-gas at or above 5 tonnes CO2 equivalent (with exemptions for some hermetically sealed equipment below 10 tonnes). Many VRF and larger split systems qualify.
What is CO2 equivalent?
The refrigerant charge in kilograms multiplied by its global warming potential (GWP), divided by 1,000. It puts every refrigerant on the same scale.
