An inspection is not the same as a maintenance visit or an exhaustive fault diagnosis. Its purpose is to assess accessible equipment, review relevant records and identify concerns such as restricted airflow, damaged door seals, corrosion or signs of refrigerant leakage. We are REFCOM F-Gas registered. Call 07427 826446 to discuss your equipment, access arrangements and the inspection scope; a fixed written quote is provided before work starts.
When a Refrigeration Inspection Is Useful
An inspection is particularly useful before taking over a London café, leasing a restaurant kitchen or bringing an unused cold room back into operation. Equipment can look presentable while having damaged insulation, poor condenser ventilation or missing refrigerant records. Establishing its condition helps you decide what needs attention before storing temperature-sensitive stock. Tell us whether you need a general condition assessment, a review of a particular concern or information to support a handover between operators.
Different premises create different inspection priorities. In a basement kitchen, heat rejection and access to the condensing unit may be limiting factors. A convenience shop’s display cabinets may suffer from blocked return-air grilles or stock loaded beyond marked limits. In a pub cellar or hotel service area, drainage, damp conditions and restricted access can conceal deterioration. The inspection should reflect how the equipment is actually used, rather than treating every cabinet or cold room as an identical asset.
What the Equipment Inspection Should Cover
The starting point is identifying each asset: equipment type, model, refrigerant designation and stated charge where labels are legible. Accessible components can then be assessed, including condenser and evaporator coils, fans, pipe insulation, door gaskets, hinges, drain lines and visible electrical enclosures. Oil staining around refrigerant joints, rubbing pipework and corrosion deserve attention, but none proves a leak on its own. Inspection findings should distinguish a visible concern from a fault that has been confirmed through a separately agreed procedure.
Operating observations add context to the physical condition. Uneven frost on an evaporator, ice around a doorway, water beneath a cabinet or unusually frequent compressor starts can have several causes. These include air infiltration, obstructed airflow, drainage problems and unsuitable control settings. Where observations require equipment to be running, the operating state matters: a cabinet recovering after deliveries or completing defrost should not be judged in the same way as one that has been closed and stable for several hours.
Temperature Control and Food Storage Risks
For food businesses, an inspection should consider whether equipment condition and working practices support the temperatures required by the site’s food safety procedures. In England, foods that require chilled temperature control generally need to be kept at 8°C or below, subject to applicable exceptions. Setting refrigeration at 5°C or below is commonly recommended to provide a margin. Frozen food storage commonly targets −18°C or colder, but product instructions and the business’s food safety plan must guide the actual requirement.
A cabinet display alone does not establish the temperature of the food inside it. Sensor position, door openings, loading patterns and defrost cycles can all affect the reading. Useful inspection evidence includes recent temperature logs, alarm history and the position of stock relative to air outlets. Any agreed comparison readings should be interpreted in that context. If stock may have become unsafe, follow your food safety procedures immediately; an engineering inspection cannot certify food as safe to serve or sell.
Refrigerant Identification and F-Gas Records
The refrigerant matters because it affects environmental obligations, handling requirements and the risks associated with further work. Existing commercial systems may contain HFC refrigerants such as R404A or R134a, while other equipment may use R290 propane or R744 carbon dioxide. These are not interchangeable. R290 is flammable, and R744 systems operate at high pressures. Missing labels or uncertain service history should be recorded as limitations, not resolved by guessing from the appearance or age of the equipment.
For equipment containing F-gases, statutory leak-check duties depend on factors including refrigerant type, charge expressed in tonnes of CO₂ equivalent and any applicable exemptions. Relevant records may include previous leak checks, refrigerant additions and details of repairs. A general condition inspection does not automatically fulfil a mandatory F-Gas leak check; that requirement must be identified and included in the agreed scope. REFCOM F-Gas registration is relevant to regulated refrigerant work, but it does not turn a visual assessment into a blanket compliance certificate.
London Site Conditions That Can Affect Findings
Crowded plant areas, basement locations and enclosed service yards can make refrigeration equipment difficult to assess properly. A condenser needs a suitable air path to reject heat; boxes, neighbouring equipment or recirculating warm air can undermine performance without an obvious failure inside the refrigerated space. Inspection should consider the surrounding environment as well as the unit itself. Grease deposits near commercial cooking equipment, damaged external pipe insulation and exposed supports can also indicate conditions likely to accelerate deterioration.
Before arranging access, identify where the associated plant is located and whether any landlord or managing-agent permission is needed. A cold room may have its condensing unit on a roof, in a shared yard or behind a locked service area. Tell us about loading restrictions, staff-only areas and any limits on switching equipment off. Concealed pipework, inaccessible components and equipment that cannot safely be operated may limit the assessment; those limitations should remain clear when decisions are made from the findings.
Define the Scope and Decide What Happens Next
Agree what you need from the inspection before the visit, including which assets are included and whether you require written findings or photographs. A useful condition record separates urgent safety or stock-protection concerns from deterioration that can be planned around. It should also identify unanswered questions. An inspection cannot establish every internal component’s condition or predict remaining service life with certainty. If a concern needs intrusive investigation, electrical measurements or refrigerant-circuit testing, that should be identified as further work rather than assumed to be included.

Frequently asked questions
Is a refrigeration inspection the same as servicing?
No. An inspection assesses condition and identifies concerns within an agreed scope. Servicing involves planned tasks intended to keep equipment operating properly, which may include cleaning or adjustments. An inspection might reveal that a condenser needs cleaning or a door seal needs attention, but that does not mean those tasks are included. Explain whether you need an independent view of condition or work carried out on the equipment so the quote matches your requirements.
Can you inspect refrigeration before I take over a business premises?
A pre-handover inspection can help establish the visible condition of existing refrigeration and highlight gaps in equipment information. Obtain the current operator’s permission, arrange access to remote plant and request available service records and temperature logs. Ideally, equipment should be operating under representative conditions. A short inspection cannot guarantee future reliability, particularly if units have been switched off or emptied, so any restrictions on assessing performance need to be understood.
Does every commercial fridge need a statutory F-Gas leak check?
No. The obligation depends on the refrigerant and charge, with thresholds generally assessed in tonnes of CO₂ equivalent and exemptions applying in some circumstances. Equipment using R290 propane or R744 carbon dioxide is not subject to F-Gas leak-check duties simply because it is commercial refrigeration, although other safety responsibilities remain. Send a clear photograph of the refrigerant label and any existing records so the relevant requirements can be considered before the scope is agreed.
Do I need to empty the fridge or close the kitchen?
Not automatically. Access requirements depend on the equipment and the agreed inspection scope. Clear working space around accessible components and avoid blocking air grilles, but do not move stock without maintaining its required storage conditions. Some observations are most useful while equipment is running normally. If isolation, internal access or disruption to food preparation may be necessary, discuss this beforehand so the business can plan safe access and alternative storage where needed.
What information should I provide when booking?
Provide the site address, number and type of units, their locations and the reason for inspection. Photographs of equipment labels, recent temperature records and details of visible ice, water or damaged parts are useful. Mention rooftop plant, locked areas or landlord access requirements. Call 07427 826446 between 07:00 and 21:00, seven days a week, to discuss the scope. A fixed written quote is provided before work starts.
