Commercial Refrigeration London: Design, Install, Repair and Servicing
Restaurants, shops, labs and warehouses across the capital all need cooling they can trust. One failed compressor can cost a day of stock. ColdTec designs, installs, repairs and services commercial refrigeration London businesses rely on. That runs from a single display fridge to a full warehouse cold store.
Every engineer holds F-Gas certification, and the company is on the Refcom register. You get a fixed price before work starts, and a signed sheet when the job is done.
Credentials You Can Check Yourself
Anyone can print a logo on a van. These four you can verify before you pick up the phone.
Check the Refcom register, the TrustMark register and the Constructionline register yourself. We would rather you did. The same checks apply to bigger work, and our Cold Room Contractors guide sets them out step by step.
What Commercial Refrigeration London Covers
Commercial refrigeration London work falls into four jobs: design, install, repair and service. Most sites need all four at some point. One contractor who knows your equipment history handles every one of them.
We handle walk-in chillers, freezer rooms, blast freezers, cold stores, display counters, cellar cooling and process cooling. Sizing comes first. An undersized unit runs flat out and burns power, while an oversized one short-cycles and wears out early. Our team measures your load before recommending anything.
Process cooling for factories and production lines is a different discipline, covered by our Industrial Refrigeration Services team.
If you already know you need a new room, our Cold Room Installation London page covers the build in detail. Bigger sites are covered by warehouse cold room installation.
System Types Compared
These are the five systems we install most often across London, and what each one suits best.
| System Type | Temperature Range | Typical Use |
|---|---|---|
| Walk-in chiller | 0°C to +5°C | Restaurants, cafes, florists |
| Walk-in freezer | −18°C to −22°C | Butchers, ice cream, frozen goods |
| Blast chiller | +70°C to +3°C fast | Commercial kitchens, catering |
| Cold store | +2°C to +8°C | Warehouses, distribution hubs |
| Display refrigeration | +2°C to +8°C | Shop counters, supermarket aisles |
What Commercial Refrigeration Costs in London
Price is the first question everyone asks, so here it is in plain numbers. Every figure covers supply, installation, commissioning and paperwork. No extras appear later.
| Equipment | Supplied and Installed | What That Covers |
|---|---|---|
| Undercounter fridge | £650 – £1,400 | Unit, delivery, positioning, commissioning |
| Display chiller, single door | £1,400 – £3,200 | Unit, shelving, lighting, temperature setup |
| Multi-deck display, 3m | £5,000 – £11,000 | Unit, night blind, install, waste heat check |
| Walk-in cold room, 3m x 3m | £9,000 – £15,000 | Panels, floor, door, plant, pipework, F-Gas record |
| Walk-in freezer, 4m x 3m | £15,000 – £25,000 | Thicker panels, floor heating, freezer plant |
| Blast chiller, 10 tray | £7,000 – £14,000 | Unit, install, staff training, HACCP records |
London adds two costs other regions do not: congestion and parking charges, and restricted delivery windows. We price both into the first quote rather than billing them as extras. Compare us against other cold room contractors and you will see the same pattern.
Installation: Our Four-Step Process
A new system should not disrupt your trading. Commercial refrigeration London installations follow the same four steps so you always know what happens next.
- Free site survey. An engineer measures the space, checks the floor, and looks at power and drainage. We also check access, because a London basement with a narrow stair changes the whole plan.
- Design and fixed quote. You get drawings and one price. That price does not move unless you ask for extra work.
- Install around your hours. We plan panel work and motor fitting around your opening hours. You keep serving customers.
- Test and hand over. We run the system under real load, confirm it holds, and issue signed F-Gas paperwork.
Most standard installs finish in three to five days. Larger cold stores take longer, and we tell you that upfront rather than after work starts. Full design work sits under commercial refrigeration installation, and single-room builds run through Commercial Cold Room Installation.
Repairs and 24/7 Emergency Cover
Breakdowns do not wait for office hours. Our repair vans run day and night, every day of the year, carrying the parts that fail most often.
Our refrigeration engineers work on every major brand used in the UK, including Copeland, Bitzer, Foster, Williams, Gram, Hubbard and True. Older units are no problem — we source parts for discontinued models too.
| Fault | What You Notice | What We Do |
|---|---|---|
| Unit losing temperature | Readings climb, alarms sound | Test gas levels, find and seal the leak, recharge |
| Ice building up | Ice blocks airflow, stock freezes unevenly | Repair the defrost heater, timer or sensor |
| Motor running non-stop | Power bills climb, door seals feel loose | Fit new magnetic seals and realign hinges |
| Fan noisy or dead | Grinding sound, or no airflow | Replace the motor or blade from van stock |
| Power keeps tripping | Circuit breaker cuts out repeatedly | Trace the electrical fault and replace the failed part |
Call before 2pm and we aim to reach a central London site the same day. Sites inside the M25 usually get a visit within four hours. For round-the-clock help, use our 24/7 Emergency Refrigeration Repair line.
Recent London Jobs
Three jobs from the last few months. Names withheld at the client's request, but the numbers are real.
Restaurant group, Shoreditch E1
Two failing upright freezers in a basement kitchen with no lift access. We stripped both units on site, carried the shells up a single flight of stairs, and rebuilt them with new compressors and door seals. Work ran from 11pm to 5am so service carried on the next day.
Result: Both units holding −20°C within six hours of restart. No service lost, and the client avoided a £9,000 replacement bill.
Independent butcher, Wimbledon SW19
A 4m x 2.5m walk-in chiller that could not hold temperature through summer. The plant was undersized and the door seal had perished. We replaced the condensing unit with a correctly sized inverter set, fitted a new sealing strip and re-hung the door.
Result: Room now holds +3°C on the hottest days. The client's electricity bill dropped by roughly a fifth.
Pharmacy, Camden NW1
A vaccine fridge failing its twice-daily temperature log. The controller was drifting by two degrees. We fitted a new calibrated controller with a data logger, mapped the cabinet temperature across nine points, and issued the calibration certificate.
Result: Audit passed with no findings. The pharmacy now downloads its records monthly instead of logging by hand.
Servicing and F-Gas Compliance
Planned servicing catches worn parts before they cost you stock. A commercial refrigeration London service plan also keeps your logbook clean. That matters, because the law makes gas leak checks a duty.
UK rules say how often you must check a system. It depends on how much refrigerant the system holds. You can read the detail on the GOV.UK F-Gas guidance pages. You can check our engineers on the Refcom register yourself.
What a Service Visit Includes
- Coil cleaning: Dust and grease come off so the motor runs cool.
- Gas checks: Joints get tested for leaks and logged.
- Electrical testing: Loose connections tighten before they cut power.
- Defrost tuning: Timers and heaters get set so ice never blocks airflow.
- Temperature verification: Sensors confirm the room matches the control panel.
- Door and seal check: Seals and hinges get tested, because a bad seal wastes more power than most faults.
Visits run under our Cold Room Maintenance and Repair contracts, which also cover breakdown call-outs.
Food businesses also need written temperature records. GOV.UK explains how to build a food safety management system, and our service sheets slot straight into that file. Chilled food must sit at 8°C or below in England.

Frequently Asked Questions
How much does commercial refrigeration cost in London?
A single display unit starts around £2,000. A full walk-in cold room usually falls between £9,000 and £25,000 depending on size, temperature and panel thickness. We survey first and quote a fixed price.
How often should commercial refrigeration be serviced?
Once or twice a year suits most sites. Kitchens that run long hours, or systems with large refrigerant charges, may need checks every three to six months to stay compliant.
Do you repair all refrigeration brands?
Yes. Our engineers work on every major brand used in the UK, including Copeland, Bitzer, Foster, Williams, Gram, Hubbard and True, and we source parts for discontinued models.
How fast can you reach a site inside the M25?
Usually within four hours. Call before 2pm and we aim to reach a central London site the same day, seven days a week.
Are your engineers F-Gas certified?
Yes. Every engineer holds F-Gas Category 1 certification, and the company is registered with Refcom. UK law requires both for anyone handling refrigerant.
Can you work outside normal trading hours?
Yes. We plan installations and servicing around your opening hours, including evenings and Sundays, so you do not have to close.
Do you charge a call-out fee for London?
We quote the call-out and the first hour together, before an engineer is dispatched. If we fix the fault in that time, that is all you pay. Congestion and parking charges are inside the price, never added after.
Which London boroughs do you cover?
All 32 boroughs plus the City of London. Target arrival runs from one hour in the south west, where our hub sits, to five hours in the far north and east.
Can you service equipment another company installed?
Yes. Most of our London work is on systems we did not build. We start with a full condition survey so you know what you own before we quote any repair.
What temperature should my commercial fridge run at?
UK food safety law says chilled food must stay at 8°C or below. We set most units between 1°C and 5°C, which leaves a safe margin when the door opens.
