F-Gas Compliance: What UK Businesses Must Know About Refrigeration Systems

F-Gas regulations don’t just apply to engineers — they apply to building owners, facilities managers and businesses operating refrigeration and air conditioning systems.
From retail and hospitality to offices and industrial facilities, any organisation using equipment containing fluorinated gases (F-Gases) has legal responsibilities. And with increasing enforcement and refrigerant phase-downs underway, understanding those responsibilities has never been more important.
If your business operates refrigeration or air conditioning systems, here’s what you need to know.
What Are F-Gases — and Why Are They Regulated?
Fluorinated gases (F-Gases), including hydrofluorocarbons (HFCs), are commonly used in:
Commercial refrigeration systems
Air conditioning systems
Heat pumps
Some fire protection systems
While effective as refrigerants, many F-Gases have a high Global Warming Potential (GWP). Because of their environmental impact, the UK has retained and strengthened regulations originally introduced under EU law to control their use, reduce emissions and phase down high-GWP refrigerants.
Guidance published via GOV.UK makes clear that businesses operating equipment containing F-Gas must ensure systems are properly maintained, leak-checked and documented.
Compliance is not optional — it is a legal requirement.
Who Is Legally Responsible?
One of the most misunderstood aspects of F-Gas compliance is responsibility.
1. Qualified Individuals
Anyone installing, servicing, maintaining or leak-checking F-Gas systems must hold a recognised F-Gas qualification. This ensures refrigerants are handled safely and legally.
2. Certified Companies
Businesses carrying out work on third-party F-Gas systems must hold company certification through an approved body such as REFCOM. Certification confirms that:
Qualified engineers are employed
Appropriate tools and recovery equipment are available
Proper procedures are in place
3. System Operators (You)
Crucially, the “operator” — typically the building owner, landlord or business controlling the equipment — is legally responsible for ensuring compliance.
This includes:
Arranging mandatory leak checks
Ensuring only certified contractors carry out work
Maintaining accurate records
Even if maintenance is outsourced, responsibility cannot be outsourced.
Leak Detection Requirements
F-Gas systems must undergo leak checks at intervals determined by the quantity and type of refrigerant within the system.
While requirements vary depending on CO₂ equivalent thresholds, the principle is simple:
The higher the refrigerant charge and GWP, the more frequent the inspection requirement.
If a leak is identified:
It must be repaired without undue delay
A follow-up check is required to confirm effectiveness
Failure to carry out mandatory leak detection can result in enforcement action from regulators such as the Environment Agency.
Record-Keeping Obligations
Documentation is a critical — and often overlooked — element of F-Gas compliance.
Operators must maintain detailed records, including:
Type and quantity of refrigerant installed
Quantity added during maintenance
Quantity recovered during servicing or disposal
Dates and results of leak checks
Details of the engineer and company performing the work
These records must typically be retained for several years and made available during inspections.
In practice, this is where many businesses fall short — not because systems are poorly maintained, but because documentation is incomplete or disorganised.
Compliance is not just about system performance. It’s about proof.
Refrigerant Phase-Down and Future Restrictions
The UK is progressively reducing the availability of high-GWP refrigerants as part of its environmental commitments.
This means:
Certain refrigerants are already restricted in new equipment
Availability of high-GWP gases is tightening
Costs for phased-down refrigerants are increasing
For businesses operating older refrigeration systems, this has real commercial implications. Systems that rely on high-GWP refrigerants may become:
More expensive to maintain
Harder to repair
Candidates for planned replacement
Forward-thinking businesses are already reviewing refrigerant types and long-term system strategy.
What Happens During an Inspection?
If your site is inspected, regulators or auditors will typically request:
Evidence of leak testing schedules
Maintenance documentation
Refrigerant usage records
Proof of contractor certification
If records are missing or incomplete, enforcement action may follow — even if no active leak is present.
This is why reactive servicing is rarely sufficient for compliance.
How Planned Maintenance Protects Your Business
The simplest way to manage F-Gas obligations is through a structured, planned maintenance approach.
Planned maintenance helps to:
Ensure leak checks are carried out on schedule
Identify refrigerant issues before they escalate
Maintain complete compliance documentation
Reduce emergency call-outs
Protect energy efficiency
Refrigerant leaks are not just compliance risks — they increase operating costs and reduce system performance.
By integrating F-Gas compliance into a broader HVAC maintenance strategy, businesses can protect both their legal position and their operational efficiency.
Compliance Is About Control, Not Crisis
F-Gas regulations are designed to reduce environmental impact — but for businesses, they are also about risk management.
Understanding your responsibilities, ensuring systems are properly maintained and keeping accurate records reduces the likelihood of fines, disruption and reputational damage.
If you’re unsure whether your refrigeration or air conditioning systems are fully compliant, a structured compliance review can provide clarity and confidence.
