A cold room is not a fridge. It cannot be wheeled out and swapped for another one. It bolts into the building, runs every hour of every day and protects everything that is sold.
Choose well and the room pays back for years. Choose badly and the cost is paid twice: once to build it and once to put it right.
What Cold Room Contractors Actually Do
Most people think the job is only the build. It is not. A good contractor runs the whole project, from the first sketch to the last service visit.
- Survey the site and measure the space
- Work out the heat load from stock and door traffic
- Draw the room and size the refrigeration plant
- Build the panels, floor, frame and doors
- Fit the plant, run the pipework and wire the controls
- Commission the room and prove it holds temperature
- Hand over certificates, manuals and a service plan
- Return four times a year for servicing
Many firms do only one or two of these steps and hand the rest to someone else. Then the room fails, the panel firm blames the refrigeration firm, and the refrigeration firm blames the electrician. Stock sits in a warm room while they argue.
How to Choose Between Cold Room Contractors
Price alone is a poor guide. Use this table, print it if needed, and take it to every quote meeting.
| What to check | A good contractor | A warning sign |
|---|---|---|
| F-Gas card | Shows it before being asked | Goes quiet when it is raised |
| Company register | Sits on the Refcom register | "We use a subcontractor" |
| Insurance | Sends a copy with the quote | Cannot produce the policy |
| Written drawings | Included free, before payment | "We'll sort that out on site" |
| Fixed price | One number, in writing | An estimate that "may move" |
| Completion date | A real date in the contract | "Should be a few weeks" |
| Warranty | Panels and workmanship, in writing | "Don't worry, we'll look after you" |
| Aftercare | Offers a service contract | No service offer at all |
Credentials Every Cold Room Contractor Must Hold
UK law sets the bar. Proof of all three credentials below should be seen before anything is signed.
Any firm can be checked for free. Search the Refcom register for F-Gas work, TrustMark for vetted trades and Constructionline for accredited contractors. The official UK F-Gas guidance for users and operators explains what the law asks of businesses.
| Certificate | What it proves | How to check it |
|---|---|---|
| F-Gas certificate | The engineer may legally handle refrigerant | Ask to see the card |
| Refcom registration | The company sits on a UK F-Gas register | Search the Refcom register |
| Public liability insurance | Cover is in place if something goes wrong | Ask for a copy of the policy |
Red Flags When Hiring a Contractor
Walk away if any of these appear. Each one costs money later.
- A price with no survey. Nobody can price a cold room without seeing the site.
- No drawings. If a contractor cannot draw it, it cannot be built to spec.
- Cash only. A real firm invoices and leaves a paper trail.
- No F-Gas number. Refrigerant work without one breaks the law.
- "We can start tomorrow." Speed is good. Skipping the survey is not.
- No service offer. A cold room needs care every three months.
- A quote in 20 minutes. A real quote needs a survey and a load calculation.
What a Cold Room Costs in the UK
Many cold room contractors quote on panel area alone, and that is how budgets break. The plant, the floor, the electrics and the commissioning all cost money too.
| Room size | Typical use | Guide price, installed |
|---|---|---|
| 3m x 3m chiller | Small kitchen, farm shop | £9,000 – £14,000 |
| 5m x 4m chiller | Restaurant, butcher | £15,000 – £24,000 |
| 6m x 4m freezer | Food production | £22,000 – £34,000 |
| 10m x 8m chiller | Distribution, wholesale | £40,000 – £65,000 |
| 15m x 20m warehouse | 3PL, bulk storage | £120,000 and up |
These are guide prices. Each one covers panels, plant, installation and commissioning. ColdTec surveys for free and then gives one fixed number, in writing, before any money changes hands. Bigger projects are covered on the warehouse cold room installation page.
Ten Questions to Ask Before Signing
A good contractor answers every one without hesitation. If even one is dodged, keep looking.
- 1. Will the site be surveyed before a quote is given?
- 2. Is F-Gas certification held, and is the company on the Refcom register?
- 3. Can the insurance certificate be seen?
- 4. Who does the electrics, and who signs them off?
- 5. What panel thickness is specified, and why?
- 6. How is the size of the refrigeration plant worked out?
- 7. What is the completion date, in writing?
- 8. What happens if the room does not hold temperature?
- 9. What warranty is given, and is it in writing?
- 10. Who services it afterwards, and what does that cost?
Why Businesses Pick ColdTec
ColdTec cannot promise to be the cheapest. It can promise there will be no surprises.
One Contract, One Phone Number
Design, build, commissioning and service all sit with one firm. When something needs fixing, there is nobody else to blame.
Drawings Before Payment
The free survey comes with a drawing, a panel spec and a plant size, so the buyer sees exactly what is being bought.
Work Around Trading Hours
Installation runs early mornings, evenings and weekends, so the business keeps trading.
A Named Engineer
One engineer runs the job, knows the site and answers calls. No call centre.
Snag List Closed at Handover
The room is tested, every fault is listed and every fault is fixed before sign-off.
Everything in Writing
Price, panel spec, plant size, completion date, warranty and service plan are all on paper before work starts.
How a Cold Room Project Runs
Free survey
The site is measured, power and drains are checked, and the way the business works is noted.
Drawings and fixed price
One number. Not an estimate. Not a range.
Approval
Nothing starts until the drawing and price are signed off.
Build
Working hours are agreed first, then kept.
Commissioning
The room runs, temperatures are logged, alarms are set and readings are shown.
Snag list
Every fault is listed and fixed before handover.
Handover pack
Certificates, F-Gas record, manuals and a service plan.
Warranty and Aftercare
Every room carries a written warranty on the panels, the plant and the workmanship. A service contract with four visits a year is also available.
Servicing matters more than most people think. A cold room that never sees an engineer runs hotter, costs more and fails early. The cold room maintenance and repair page shows what is covered, and the refrigeration engineers who do the work are listed too.
If it breaks, the phone is answered at any hour. The 24/7 emergency refrigeration repair team stocks the parts that fail most often.

Cold Room Contractor FAQs
How can I tell if cold room contractors are properly certified?
Ask for the engineer's F-Gas card and the company's Refcom number, then check both on the Refcom register and TrustMark. A real contractor hands these over without being asked twice.
Should I take the cheapest quote?
Usually not. A cheap quote often means thin panels, an undersized plant or no commissioning. Those three cost far more in electricity and breakdowns than the saving. Compare drawings, panel thickness and plant size, not just the total.
How long does a cold room installation take?
A small walk-in room takes about a week. A large warehouse store takes six to ten weeks. A completion date is given in writing, and it is kept.
Is planning permission needed for a cold room?
Usually not for a room inside an existing building. Consent may be needed for an external plant compound or a change of use. This is flagged at survey, along with advice on whether to ask the local council.
Can the contractor work alongside my own builder?
Yes. Work with main contractors, shopfitters and builders is common. Drawings, power requirements and the programme are shared up front.
What warranty is given?
A written warranty covers panels, refrigeration plant and workmanship. The documents arrive in the handover pack.
Are cold rooms built by other firms serviced?
Yes. Most makes are serviced and repaired, including Copeland, Bitzer, Danfoss, Carrier and Searle. An honest view is given on whether repair or replacement is the better return. See cold room maintenance and repair.
