Walk-In Cold Rooms : The Complete UK Guide (2026)

A walk-in cold room replaces multiple upright fridges with a single modular unit — at lower running cost, greater capacity, and full UK food hygiene compliance. This guide covers every TEFCOLD modular cold room size, installation planning, and the running cost comparison that makes the decision easy.

If you’re running out of fridge space — or spending a fortune replacing upright fridges every few years — a walk-in cold room is almost certainly cheaper in the long run. A single modular cold room can replace three or four commercial upright fridges, run on less energy than the units it replaces, and last 15–20 years with basic maintenance.

This guide covers everything you need to know before you buy: UK food law, how to read the model numbers, which size suits your operation, what the real running costs look like, and how FridgeSmart’s TEFCOLD walk-in cold room range stacks up from the smallest 1.2m × 1.2m unit right up to custom configurations.

Cold Room vs Multiple Upright Fridges

This is the question most buyers start with. The short answer: if you need more than about 3m³ of chilled storage, a cold room almost always wins on cost, energy, and usability within a few years. To reduce your cold room running costs further, read our guide to cutting commercial fridge energy bills.

TEFCOLD Chiller Rooms — Four Sizes Compared

TEFCOLD’s CRPF chiller room range runs from a compact 1.2m × 1.2m starter room up to a 3.0m × 3.0m full commercial unit. All models run at 0°C to +8°C, use R290 natural refrigerant, and are plug-in ready after assembly — no specialist refrigeration engineer needed to commission them. Below are four representative sizes spanning the common catering range.

Need a Freezer Room Instead?

The CRNF freezer room range is TEFCOLD’s negative-temperature counterpart — running at −20°C to −10°C, with 120mm insulation panels (vs 80mm on the chiller range) and a beefier compressor to handle the colder temps. If you’re holding ice cream, raw meat for ageing, or bulk frozen prep, this is what you need. Under the Food Hygiene (England) Regulations 2006, frozen foods must be maintained at −18°C or below — the CRNF range, set to its coldest point, comfortably meets this requirement.

Size Guide: Which Model Do You Actually Need?

The TEFCOLD model number directly encodes the external footprint: CRPF + width(dm) + depth(dm). So CRPF1818 = 1.8m × 1.8m external. All models share the same 2,200mm external height.

What Temperature Do You Need?

Not all food has the same storage requirement. Use this table to confirm whether a chiller room (CRPF, 0 to +8°C) or a freezer room (CRNF, −20 to −10°C) is right for your operation — or whether you need both.

Planning Your Installation

Modular cold rooms are designed to be self-installed or assembled by a builder in a day or two. That said, there are four things worth sorting before the unit arrives.

7 Things to Check Before You Order

• 
  ✓
  
  
  Measure the footprint twice
  External dimensions are 60mm wider per side than internal. A CRPF1818 needs a 1.8m × 1.8m floor space plus service clearance. Don’t forget door swing room — the door opens outward.
  
  
  
• 
  ✓
  
  
  Chiller or freezer?
  The CRPF chiller range (0 to +8°C) suits all chilled food. The CRNF freezer range (−20 to −10°C) is for frozen stock. If you need both — and you have the space — they can sit back to back to share a wall and reduce heat loss.
  
  
  
• 
  ✓
  
  
  Square or rectangular?
  If your back-of-house is long and narrow, a non-square configuration (e.g. CRPF1227 = 1.2m × 2.7m) may suit you better than a square room. The full walk-in cold room range includes many non-square options at competitive prices.
  
  
  
• 
  ✓
  
  
  Shelving needs
  The TEFCOLD range is supplied with anti-slip flooring but shelving is sold separately. Factor in the cost of wire shelving kits — they’re not expensive but you want to plan the internal layout before the unit arrives.
  
  
  
• 
  ✓
  
  
  Temperature monitoring & logging
  UK food law requires a temperature record. The electronic controller on every TEFCOLD cold room has a built-in display — you can log daily readings manually. For automated monitoring (especially useful for overnight), add a wireless temp sensor and a basic data logger.
  
  
  
• 
  ✓
  
  
  Ambient temperature of the room
  All TEFCOLD cold rooms are rated to Climate Class 4 (max 32°C ambient). If your kitchen regularly exceeds this in summer, or the unit is in direct sunlight, consider a Climate Class 5 configuration or position it in a cooler area.

  Service plan
  Annual servicing keeps your cold room running at peak efficiency and catches door seal wear before it becomes a compliance issue. Budget roughly £150–£250/year for a maintenance visit.
  
  
  

What Does a Cold Room Actually Cost to Run?

Upfront price is only part of the picture. The real question is total cost of ownership over 15 years compared to three or four upright fridges doing the same job.
