Immediate steps — do these now
A cold room failure is one of the most costly emergencies a food business faces. Stock loss, food safety risk and service disruption can compound quickly if the first 30 minutes are not managed correctly. Follow these steps in order.
Call 020 3002 6826 immediately. The sooner the engineer is on the way, the sooner the room is back at temperature and the less stock you lose. Do not spend time diagnosing the fault yourself — this is the single most important step.
Note the temperature reading on the cold room display or a probe thermometer the moment you discover the fault. Write it down with the time. This is the evidence your insurer and the engineer will need. A screenshot or photo of the display is ideal.
Every time the door opens, warm air enters and accelerates temperature rise. A closed, well-insulated cold room will typically hold safe temperatures for 2–4 hours after a breakdown. Resist the urge to check on the stock — it is doing better with the door shut.
Contact neighbouring businesses, suppliers or hire companies about temporary cold storage if the repair is likely to take more than 2 hours. Priority items are high-value, high-risk stock: raw meat, dairy, fish and prepared foods. Know where you will move them before you need to.
Log the time of discovery, temperature reading, who was notified and what actions were taken. If you have a food safety management system, record the event there. This documentation supports both your insurance claim and your food hygiene compliance records.
Temperature safety — what the rules say
UK food safety law requires chilled food to be kept at or below 8°C, with 5°C recommended as best practice. Once your cold room rises above 8°C, the clock is running on perishable stock.
| Cabinet temperature | Status | Action required |
|---|---|---|
| 0°C – 5°C | SAFE | Monitor. Keep door closed. Engineer on the way. |
| 5°C – 8°C | MONITOR | Legal limit approaching. Prioritise moving high-risk stock. |
| 8°C – 12°C | ACT NOW | Above legal limit. Move perishable stock immediately. Document everything. |
| Above 12°C | UNSAFE | High-risk stock is likely unsafe. Do not serve. Record and photograph before disposal. |
Before disposing of stock: photograph everything and record the value. Your insurer will require evidence of stock lost. Do not dispose of anything until it is documented — even if you cannot save it.
What to tell the engineer
When you call, have the following information ready. It allows our engineers to carry the right parts and reduces the chance of a second visit.
- Make and model of the cold room unit or condensing unit — on a data plate inside the room or on the external condensing unit
- Current temperature reading — what the display shows now
- When it was last working normally — end of last service, this morning, yesterday
- Any warning signs beforehand — unusual noise, ice build-up, temperature creeping up over days
- Any recent work on the system — recent repair, installation, building work nearby
- Your address and access details — which entrance, any parking restrictions
If you cannot find the model number, a photograph of the data plate sent via WhatsApp (07429 262 544) allows our engineers to identify the unit before arrival.
Common causes of cold room breakdown
Understanding what went wrong helps prevent it happening again. These are the faults our engineers attend most frequently on London cold room callouts.
Grease and dust block airflow. The most common preventable cause. A condenser clean every 6 months eliminates this fault entirely.
Gradual loss of refrigerant causes temperature drift over days or weeks before complete failure. F-Gas compliant repair and recharge required.
Worn or split seals allow warm air in continuously. Ice builds up around the evaporator, eventually blocking airflow and causing the unit to stop cooling.
Evaporator or condenser fan motors fail with age or overheating. The unit runs but cannot circulate air, causing temperature to rise gradually.
Electronic control boards can fail due to power surges, moisture or age. The condensing unit may not start, or the temperature setpoint cannot be maintained.
The compressor is the heart of the refrigeration system. Failure is often preceded by other unaddressed faults — a fouled condenser forcing the compressor to overwork is a common cause.
Insurance and stock loss claims
Many commercial insurance policies include cover for stock loss due to equipment failure. Whether your claim is accepted — and how much you recover — depends almost entirely on the documentation you produce.
To support an insurance claim after a cold room breakdown, you will need:
- Temperature log — the reading at time of discovery and subsequent readings
- Time of fault discovery — when the problem was first noticed and by whom
- Photographic evidence of stock — before disposal, photograph everything that was lost
- Stock valuation — a written record of what was lost and its value
- Engineer's report — Bear Building Services provides an invoice with report after every breakdown visit, confirming the fault, the repair carried out and the date
Keep the engineer's report. The written confirmation of the fault from a qualified F-Gas certified engineer is the document your insurer will request. Bear Building Services provides an invoice with report after every callout — keep it on file.
How to prevent it happening again
The majority of cold room breakdowns our engineers attend in London are preventable. A fouled condenser, a failing door seal, a gradual refrigerant leak — these are all faults that a twice-yearly PPM visit will catch and fix before they become a crisis.
For London restaurants and hotels, the calculation is straightforward: a single cold room failure costs far more in stock loss, emergency callout rates and lost service than a year's maintenance contract. Operators who experience one serious breakdown rarely skip maintenance again.
A Bear Building Services maintenance contract includes condenser cleans, door seal checks, temperature verification and priority emergency callout — with a maintenance sheet and report after every visit. View contract tiers and request a free site assessment.
Frequently asked questions
What should I do if my cold room breaks down?
Call a refrigeration engineer immediately — call 020 3002 6826 for a 4-hour emergency response across London. Record the current cabinet temperature, keep the door closed, and move temperature-sensitive stock to alternative cold storage if the temperature is approaching 8°C.
How long can a cold room hold temperature after breaking down?
A closed cold room will typically hold safe temperatures for 2–4 hours after a breakdown, depending on the ambient temperature, insulation quality and how full the room is. A fuller room holds temperature longer. Keep the door closed and call an engineer immediately.
At what temperature does cold room stock become unsafe?
UK food safety law requires chilled food at or below 8°C, with 5°C recommended as best practice. If your cold room rises above 8°C for more than 4 hours, perishable stock should be treated as unsafe. Document the temperature reading the moment you discover the fault.
How quickly can a refrigeration engineer attend in London?
Bear Building Services targets a 4-hour emergency response across all 32 London boroughs. Call 020 3002 6826 — you speak directly to our engineers, not a call centre or booking queue.
Can a cold room breakdown be covered by insurance?
Many commercial policies cover stock loss due to equipment failure. You will need a temperature log, photographs of stock before disposal, a stock valuation and an engineer's report confirming the fault. Bear Building Services provides an invoice with report after every breakdown visit.
What are the most common causes of cold room breakdown?
Fouled condenser coils, refrigerant leaks, door seal failure, fan motor failure and control board faults. Most are preventable with twice-yearly planned maintenance — a condenser clean every 6 months eliminates the most common cause entirely.
