10 Best Commercial Fridges for UK Restaurants in 2026

Choosing the right commercial fridge is one of the most consequential equipment decisions a restaurant owner makes. Get it wrong and you're dealing with food safety failures, energy bills that eat into your margins, and kit that doesn't fit your workflow. Get it right and your kitchen runs smoother, your chefs work faster, and your HACCP compliance becomes far easier to manage.

This guide covers the 10 types of commercial fridges most relevant to UK restaurants in 2026, what each one does, who it suits, and the key things to look for before you buy. Whether you're fitting out a new kitchen or replacing ageing equipment, this is the starting point.

1. Upright Commercial Fridges

What it is

The workhorse of commercial refrigeration. Upright fridges — also called reach-in fridges or commercial refrigerators — are tall, freestanding units with one or more solid or glass doors. They offer high-capacity storage in a relatively compact footprint and are designed for continuous heavy use in professional kitchens.

Who it's for

Most commercial kitchens. Restaurants, hotels, contract caterers, care homes — if you're running a kitchen that produces more than 30 covers a day, you almost certainly need at least one upright fridge.

What to look for

• Capacity: Measured in litres. A 600-litre single-door unit is the standard entry point for a busy kitchen.
• Temperature range: Should hold 0°C to +4°C consistently, even when the door is opened frequently.
• Refrigerant: Look for R290 (propane) refrigerant — it's lower GWP and future-proofed against F-gas regulations.
• Door configuration: Single, double, or triple door. More doors mean better temperature recovery after opening.
• Build quality: Full stainless steel interior and exterior. Self-closing doors with strong magnetic seals.

2. Under-Counter Fridges

What it is

Under-counter fridges are designed to fit beneath a standard 900mm worktop, keeping refrigerated storage exactly where your chefs are working. They're compact — typically 60cm to 150cm wide — and built to withstand the heat and pace of a working kitchen line.

Who it's for

Any kitchen where space is at a premium and you need refrigeration at the point of use. Particularly valuable on the prep line, at the pass, or in a bar environment. Ideal for smaller operations or as supplementary cold storage in larger kitchens.

What to look for

• Depth and height: Standard undercounter units are 600mm deep and 850mm tall. Check your worktop height before ordering.
• Fan-assisted cooling: Essential for maintaining even temperature throughout the cabinet.
• GN compatibility: Look for units that accept 1/1 GN pans directly on the shelves — it saves time and reduces the need for decanting.
• Lockable doors: Useful in front-of-house or bar settings.

3. Preparation Fridges (Saladette / Pizza Prep)

What it is

Prep fridges — commonly called saladette units or pizza prep tables — combine refrigerated storage below with a refrigerated top rail that holds GN pans of ingredients at the correct serving temperature. The work surface sits between the two, giving chefs everything they need within arm's reach.

Who it's for

Pizzerias, Italian restaurants, sandwich bars, salad-focused cafes, and any kitchen with a high-volume prep station. If your chefs spend significant time assembling dishes from multiple cold components, a prep fridge will dramatically increase throughput.

What to look for

• Number of GN openings: Units typically run from 2 to 8 GN 1/3 or 1/6 pan positions in the top rail.
• Cover: A hinged cover that keeps the top rail cold when not in use extends the life of your ingredients and reduces energy consumption.
• Base storage: Check the internal layout — adjustable shelves that accept full GN trays are essential.
• Temperature performance in hot kitchens: Look for units rated to ambient temperatures of at least 38°C (Class 5 or above).

4. Display Fridges

What it is

Display fridges are designed as much for presentation as storage. They feature large glass doors or open fronts, interior lighting, and attractive finishes. The refrigeration keeps food and drink at safe temperatures while the design encourages customers to browse and buy.

Who it's for

Cafes, delis, bakeries, grab-and-go operations, and any food service business with a counter where customers self-select chilled products. Also used in hotel lobbies, staff canteens, and convenience-style dining concepts.

What to look for

• Glass type: Low-E glass reduces condensation and improves energy efficiency — important if the unit is near a heat source.
• Lighting: LED lighting throughout. It runs cooler than fluorescent and makes products look better.
• Temperature uniformity: Fan-assisted models maintain more consistent temperatures than static-cooling units — critical for front-of-house food safety.
• Noise level: Front-of-house units need to operate quietly. Check the decibel rating.

5. Back-Bar Chillers

What it is

Back-bar chillers sit behind the bar, keeping bottled beers, wines, soft drinks, and mixers at serving temperature. They typically have glass doors and attractive styling, and are built to withstand the high ambient temperatures and frequent opening cycles of a busy bar environment.

Who it's for

Pubs, bars, restaurants with a bar operation, hotels, and any venue serving chilled drinks. Even a small cafe with a licensed counter benefits from a well-chosen back-bar unit.

What to look for

• Bottle capacity: Measured in number of 330ml bottles or litres. Be realistic about your busiest service and size up accordingly.
• Temperature range: Most serve between 2°C and 8°C. Some units offer dual-zone for wine and lager at different temperatures.
• Hinged vs sliding doors: Sliding doors require less clearance behind the bar but hinge doors are generally easier to use at speed.
• Night blinds: Useful for energy saving during closed hours.

6. Blast Chillers

What it is

A blast chiller is not a storage unit — it's a process unit. It rapidly reduces the temperature of cooked food from +70°C to below +3°C within 90 minutes (soft chill) or to -18°C within 240 minutes (hard chill/blast freeze). This is the foundation of cook-chill and cook-freeze production methods.

Who it's for

Central production kitchens, large hotels, contract caterers, school meal providers, and any operation producing food in bulk for service at a later time. Under UK food safety legislation, any business using cook-chill methods is strongly advised to use a blast chiller rather than relying on ambient cooling.

What to look for

• Tray capacity: Measured in 1/1 GN trays. Match to your largest production batch.
• Soft chill vs hard chill: Many units do both. Confirm the performance figures are certified to NF D 94-003 or equivalent.
• Probe thermometer: An integrated core temperature probe is essential for accurate process control and HACCP records.
• HACCP data logging: Modern units log temperature cycles digitally — invaluable for compliance.

7. Cold Rooms (Walk-In Coolers)

What it is

A cold room — also called a walk-in cooler or walk-in fridge — is a refrigerated room built from insulated panels. It offers vastly more storage capacity than any standalone unit and allows staff to walk inside to access stock. Cold rooms can be built to almost any size and configured as fridge, freezer, or dual-temperature.

Who it's for

High-volume restaurants, pub kitchens, hotel operations, large catering companies, butchers, fishmongers, and any business receiving large deliveries that need rapid, bulk cold storage. If you're receiving more than two sizeable deliveries per week, a cold room almost always makes financial sense.

What to look for

• Panel thickness: 80mm panels for chilled storage (0°C to +4°C), 100mm or 120mm for freezer rooms (-18°C to -22°C).
• Refrigeration unit sizing: The condensing unit must be correctly sized for the room volume and the ambient conditions of its location. Undersizing causes persistent temperature failure.
• Door specification: Self-closing hinged doors with a safety release from inside are a legal requirement.
• Flooring: If staff will walk in and out on a wet kitchen floor, a ramped threshold and non-slip flooring are essential.

8. Bottle Coolers

What it is

Bottle coolers are compact, typically low-profile units designed specifically to chill bottled and canned products. Many use a chest or semi-upright configuration. They're common in convenience-style environments, and the open-top chest format is recognisable in takeaways and corner shops across the UK.

Who it's for

Takeaways, fish and chip shops, corner cafes, staff canteens, and food service operations where chilled drinks are sold but a full back-bar unit isn't required. Also used as secondary units in bars during busy periods.

What to look for

• Open vs closed top: Open-top units offer easier access and more visibility but are less energy-efficient. Closed lid units retain temperature better.
• Compressor position: Bottom-mounted compressors are easier to clean and less prone to overheating.
• Interior finish: Stainless steel or robust plastic interior for ease of cleaning.

9. Deli Counters and Serve-Over Display Cases

What it is

Deli counters — also called serve-over counters or display cases — are counter-top or floor-standing refrigerated display units where staff serve customers directly from the cabinet. They're a staple of delis, butchers, fishmongers, and any food service outlet where fresh product is sold by weight or portion.

Who it's for

Butchers, fishmongers, delis, farm shops, hotel breakfast counters, and restaurants with a front-of-house charcuterie or cheese display. They bridge food service and retail refrigeration.

What to look for

• Curved vs straight glass: Curved glass gives a more premium appearance; straight glass is easier to clean.
• Humidity control: For fresh meat and fish display, humidity management prevents product drying out and maintains appearance.
• Sneeze guard compliance: In open-counter configurations, check that the unit meets current food hygiene display requirements.
• Lighting colour temperature: Warm white LED (around 3000K) flatters fresh products; cool white can make meat look unappealing.

10. Chest Freezers

What it is

Chest freezers open from the top rather than the front. They offer excellent energy efficiency — cold air doesn't fall out when opened — and can store awkwardly shaped or bulk items that don't fit neatly on upright freezer shelves. They typically operate at -18°C to -22°C.

Who it's for

Takeaways and fish and chip shops storing bulk frozen product, caterers with large volumes of frozen stock, and businesses using chest freezers as secondary or overflow storage. Less suited to kitchens needing frequent access to many different products simultaneously.

What to look for

• Capacity: Chest freezers are available from around 100 litres (compact) to over 600 litres for commercial use.
• Fast freeze function: Useful when loading large quantities of fresh product for freezing.
• Interior baskets: Divided baskets make stock rotation and organisation manageable.
• Lock: A key lock is advisable in any shared or public-accessible environment.

Conclusion: Choosing the Right Commercial Fridge for Your Restaurant

There is no single best commercial fridge — there's only the right fridge for your menu, your volume, your kitchen layout, and your budget. Most successful kitchens run a combination of types: an upright fridge for bulk storage, under-counter units on the line, and perhaps a cold room or blast chiller for high-volume production.
