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, 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.

What Commercial Refrigeration London Covers

Commercial refrigeration London work falls into four jobs: designing a new system, installing it, repairing it when it fails, and servicing it so it does not fail. Most sites need all four at some point, which is why it pays to use one contractor who knows the equipment history.

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.

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.

  1. Free site survey. An engineer measures the space, checks the floor, and looks at power and drainage.
  2. Design and fixed quote. You get drawings and one price. That price does not move unless you ask for extra work.
  3. Install around your hours. Panel assembly and motor fitting are planned so you keep serving customers.
  4. 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.


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 engineers work on every major brand used in the UK, including Copeland, Bitzer and Foster. Older units are no problem — we source parts for discontinued models too.

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.


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, which matters because gas leak checks are a legal duty.

UK rules on fluorinated gases set how often a system must be checked, based on how much refrigerant it holds. You can read the detail on the GOV.UK F-Gas guidance pages. Our engineers are listed on the Refcom register, so you can check their credentials 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.

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.

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 £5,000 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 and Foster, 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.
