Written for the person who has ended up responsible for compliance – what the regulations cover, how to work out your leak check schedule from CO2e, what records you must hold, and what enforcement looks like.
Who these are for
If you have air conditioning, refrigeration or heat pump plant on business premises, somebody is legally the operator of that equipment. Frequently that person does not know it is them.
These guides are for:
- Facilities managers who have inherited plant and a folder that may or may not be a compliance record.
- Building owners and landlords whose tenants use equipment they own.
- Small business owners with a few split systems who have never been told any of this applies.
- Managing agents carrying the duty on behalf of a client.
- Anyone preparing for an inspection, a sale, or a lease event where this will be looked at.
Engaging a qualified contractor to do the leak checks is how you discharge the duty in practice. It does not move the legal responsibility. If the checks were not done at the right interval, or the records are not held, that is the operator’s position to answer for – not the contractor’s.
Start here, depending on where you are
| Your situation | Start with |
|---|---|
| New to this entirely | What the regulations actually cover |
| Not sure whose duty it is | Operator or contractor |
| Need to know how often to check | Leak check frequency and CO2e |
| Have records but do not trust them | What a logbook must contain |
| Want a routine you can actually run | F-Gas for facilities managers |
| Worried about being inspected | Enforcement and penalties |
| Plant running on an older refrigerant | The refrigerant phase-down |
| Removing or scrapping equipment | Decommissioning and recovery |
The mechanism, in one paragraph
Fluorinated gases are potent greenhouse gases, so the regime works by attaching a carbon-dioxide-equivalent figure to each one. Multiply the refrigerant charge in a system by that gas’s global warming potential and you get the system’s CO2e. Your obligations – whether you must have leak checks at all, and how often – follow from that number rather than from the physical size of the equipment.
Which is why two systems that look identical can have entirely different duties attached, and why the refrigerant type matters as much as the charge size.
- Leak check frequency and CO2e – how to work out your own figure and the schedule that follows.
- What the regulations actually cover – the scope, in plain English.
- The refrigerant phase-down – what the tightening supply of higher-GWP gases means for plant you already own.
Records, which is where most non-compliance actually sits
In our experience the equipment is usually fine. The records are the problem – missing, incomplete, held by a contractor who has been replaced, or in a form that proves nothing.
A compliant record is not a pile of service sheets. It has to establish, for each system, what gas and how much, who did what and when they were qualified to do it, what was found, and what was added or recovered.
- What an F-Gas logbook must contain – the specific items, and the common gaps.
- F-Gas for facilities managers – a routine that keeps it current rather than reconstructing it annually.
- Decommissioning – recovery, records and disposal, which is a duty that persists after the equipment leaves.
The practical test: if an inspector asked today, could you produce the record for every system on site, without phoning anyone? If not, that is the gap.
Enforcement
F-Gas enforcement covers who checks and what non-compliance costs. The short version is that it is enforced, the penalties are meaningful, and the operator is who they come to.
It also surfaces at moments nobody plans for – a building sale, a lease assignment, an insurance review, or a due diligence exercise. Records that were never kept cannot be created retrospectively.
See also F-Gas compliance, planned maintenance and the air conditioning guides.
Not sure whether the duty is yours, or whether your records would stand up? That is a short conversation.
Questions we get asked about this
Who is legally responsible, me or my contractor?
The operator of the equipment – which is generally whoever has actual control of it. Engaging a qualified contractor is how you discharge the duty in practice; it does not transfer it.
How do I know how often leak checks are needed?
From the system’s CO2e – the refrigerant charge multiplied by that gas’s global warming potential. The physical size of the equipment does not determine it.
We have service sheets. Is that a logbook?
Usually not. A compliant record has to establish gas type and charge, who did the work and their qualification, what was found, and what was added or recovered, for each system.
What happens if we have not been doing this?
Start now and get the records straight. They cannot be created retrospectively, and the gap is better identified by you than by an inspector or a buyer’s solicitor.
Does this apply to a small shop with two split systems?
It may well. The threshold is CO2e, not business size, and a small system on a high-GWP refrigerant can carry duties that a larger one on a low-GWP gas does not.
What about equipment we are scrapping?
Recovery by a qualified person, and records of it. The duty persists through decommissioning and is a common gap when plant is removed by a general contractor.
