Commercial Freezer Repair in London

Commercial freezer and fridge breakdowns we repair

A commercial freezer that cannot hold temperature puts frozen stock, food safety records and service at risk. We repair upright and under-counter freezers, chest freezers, blast chillers, walk-in freezer rooms, reach-in fridges and chilled preparation counters used in restaurants, hotel kitchens, pubs, takeaways and institutional catering sites.

Compressor failure is one of the most serious faults. Symptoms include a unit that hums but does not start, trips the electrical supply, runs constantly without pulling down, or cuts out on thermal overload. We test the compressor windings, start components and pressures before recommending repair or replacement, so you are not paying for a compressor when a relay, capacitor or condenser fan is the real cause.

Thermostat and controller faults show up as freezers running too warm, too cold or erratically. Door seals are a frequent and inexpensive cause of icing, condensation and long run times; a split gasket lets humid kitchen air into the cabinet, where it freezes onto the evaporator. Ice build-up can also indicate a failed defrost heater, timer, termination sensor or fan, and we identify which component is responsible rather than simply defrosting the cabinet.

Same-day process and 24/7 emergency freezer call-outs

Our same-day process is simple: call with the freezer type, temperature and symptoms; we assess urgency and book the nearest available engineer; the engineer diagnoses the fault on site and gives a clear quote; and most common faults are repaired on the first visit using parts carried on the van. Emergency cover is available 24/7, including evenings, weekends and bank holidays, for walk-in freezer rooms, cold stores, upright and chest freezers in restaurants, shops and warehouses.

Freezer failures are treated as urgent because stock losses grow by the hour. We cover restaurants, pubs, hotels, schools, care homes and food businesses across London, Surrey and towns around the M25, and calls are prioritised by stock risk, equipment type, location and engineer availability. Tell us the cabinet temperature, how long it has been rising and whether it is your only freezer so the engineer can plan the visit.

While you wait, keep doors closed, move high-value stock to a working unit if one is available, and record temperatures for your food safety log. Emergency call-outs start from £120 plus VAT, and we give free repair quotes once the fault has been diagnosed so you can decide before chargeable parts are fitted.

Brands serviced and F-Gas compliance

Our engineers work on the commercial refrigeration brands commonly found in UK kitchens, including Foster, Williams, Gram, True, Polar, Hoshizaki, Electrolux Professional and Precision. Where a part is model-specific, we confirm the model and serial number and source the correct replacement.

Any work involving the refrigerant circuit is carried out by F-Gas certified engineers in line with the F-Gas Regulations 2014. Low refrigerant normally means a leak, so we locate and repair it before recharging. Commercial freezers commonly use R404A, R448A, R449A or hydrocarbon refrigerants such as R290, and refrigerants are never mixed or substituted without confirming suitability. If a recharge is needed, see our catering refrigeration regas service.
