F-Gas regulations sit on commercial refrigeration, not on a kitchen fridge in a flat. If you run restaurants, pubs, takeaways, cafes, shops or hotels in London, the fluorinated greenhouse gas rules affect who may add refrigerant, how leaks are found, and what records you keep. This is a practical briefing for operators, not legal advice. Cold Direct works on trade cabinets and walk-ins. We do not do household repairs. For walk-in plant see commercial cold room repair London. Call 07983 759320 for a commercial engineer.
What F-Gas is trying to stop
Many catering systems still use HFC refrigerants with a high global-warming potential. The rules limit who can handle those gases, push leak checks on larger charges, and restrict topping up a leaking system as a habit. A “regas” without a leak repair is how the same hotel cold room fails every month and how gas is vented into the air. An unlicensed person adding gas from a cylinder bought online is not a workaround. It is the opposite of compliance.
Who may work on your commercial system
Leak testing, recovery, charging and breaking into the circuit are jobs for people with the right F-Gas company and personnel certification. Duty managers in takeaways and cafes should not pierce pipes or loosen Schrader caps. Your job is to notice oil stains, ice in stripes, hissing and rising temperatures, then book a certified commercial engineer. Ask to see competence if you are a group estates manager. Cold Direct attends commercial sites only.
Leak checks and records
Larger commercial systems and many cold rooms need leak checks on a schedule that depends on charge and gas type. Keep invoices, gas quantities and leak-test dates with the asset file. Hotels with several walk-ins should treat each system as its own record. Shops with a remote pack in a plant room are not the same as a self-contained Polar under-counter, but both can leak. If an EHO or insurer asks how you responded to a warm room, a folder of temperatures plus an F-Gas invoice is stronger than a verbal “we put gas in last year”.
What you should do when a cabinet or room warms
Do not keep adding refrigerant as a weekly habit. Isolate if it is safe, protect stock under your HACCP rules, and call. A commercial fridge or freezer that ices in a stripe, oils around a joint, or never holds set point after a recent “top-up” is a leak until proven otherwise. Walk-in doors that will not seal also waste energy and can look like a gas problem. Book commercial cold room repair London for rooms. Use the cabinet pillars for uprights and prep counters.
Older gases and replacement plant
High-GWP gases are being squeezed. A 15-year-old R404A pack in a restaurant may still be legal to service with conditions, but a major leak can make replacement the cheaper compliance path. We will not pretend a compressor change is always cheaper than a new cabinet. We will diagnose first. Pubs and hotels planning a refit should ask about lower-GWP options before the old plant fails on a Saturday.
Myths that cost businesses money
Myth: “It is only a small under-counter, F-Gas does not apply.” Handling the gas still needs competence. Myth: “The chef can add gas from a can.” That is how you buy a second leak and a legal problem. Myth: “Domestic engineers are cheaper and the same.” Household white-goods skills are not commercial rack skills. Cold Direct will not attend a domestic fridge. We do not do household repairs.
How Cold Direct works within the rules
We find leaks before we recharge. We quote after diagnosis. We recover gas when a circuit is opened. We will not vent refrigerant to “see if it helps”. Night call-outs for restaurants, pubs, takeaways, cafes, shops and hotels still follow the same leak-then-charge logic. Warranty covers the agreed commercial repair. Food already lost is your HACCP decision, not an F-Gas exemption.
