A commercial fridge is one of the longest-running pieces of kit in any kitchen. It works 24 hours a day, holds your stock between 2 and 8°C, and has a direct effect on food safety, waste and electricity bills. Get the type right and the kitchen runs cleanly. Get it wrong and you pay for it every quarter in spoiled stock, missed cover targets and inflated energy use. This guide covers the main fridge types, sizing, cooling methods, energy ratings and UK regulations, so you can buy with confidence. You can browse all commercial fridges at H2 once you know what you need.
What is a commercial fridge?
A commercial fridge is a heavy-duty chilled storage unit built for foodservice. It holds a steady internal temperature between 2 and 8°C, recovers quickly after frequent door openings, and is designed to run reliably in hot kitchens for years at a time. Most use stainless steel construction, stronger compressors than a domestic unit, and digital thermostats with an external readout.
The difference from a home fridge is built-in from the start. A domestic fridge expects a cool utility room and a handful of openings a day. A commercial refrigerator expects 35°C kitchen heat, dozens of openings an hour, and gastronorm trays sliding in and out through every service. It is built tougher, runs colder under load, and is rated for far longer hours.
Buying a commercial fridge also keeps you compliant. UK food safety guidance requires chilled food to be held at 8°C or below, and HACCP records expect daily temperature checks. A trade unit gives you a clear digital readout, and most modern models include an alarm if the temperature drifts.
Types of commercial fridge
There is no single best fridge. The right choice depends on what you store, where the fridge sits in the kitchen, and whether it needs to face the customer.
Upright fridge: the kitchen workhorse
An upright fridge stands tall, takes up roughly the same footprint as a domestic fridge, and gives you anywhere from 400 to 1,400 litres of chilled storage. Models come in single-door, double-door and triple-door formats with adjustable shelves and full gastronorm compatibility. This is the default choice for back-of-house storage and pairs cleanly with commercial freezers of matching width. Browse the upright commercial fridge range for single, double and triple-door options.
Undercounter fridge: prep stations and bars
An undercounter fridge fits beneath a 900 mm worktop and puts chilled stock right at the section. They are common in bars for mixers and garnishes, and in pizza or burger stations where speed matters. Capacity is typically 130 to 280 litres, but the time saved on every cover often outweighs the smaller volume. View commercial undercounter fridges for compact prep storage.
Bench and counter fridge: storage and worktop in one
A bench fridge combines chilled storage with a stainless steel worktop on top. Single, double, triple and four-door options give you a long counter for prep with full chilled storage underneath. They suit sandwich bars, takeaways and any kitchen that is short on floor space. See the bench fridge range for sizes from 100 cm to over 200 cm wide.
Display fridge: front of house
A display fridge is built to show off the stock as much as chill it. Glass doors, internal LED lighting and adjustable shelves turn a fridge into a merchandising tool. Display fridges drive impulse sales in cafés, delis, forecourts and convenience stores. Within the display category there are four common formats.
A multideck display fridge has an open front with multiple shelves and is the format you see in supermarkets and food-to-go counters. A single door glass display fridge is the most popular café and pub option, with a hinged glass door and 200 to 500 litres of capacity. A commercial drinks fridge keeps bottled and canned drinks at serving temperature with high visibility. A cake display fridge uses curved or panoramic glass with humidity control to keep cakes, pastries and desserts looking fresh through a full trading day. Browse the full display fridge range to see all four formats together.
Prep counter fridge: pizza and salad sections
A prep counter fridge has a refrigerated well on top for ingredient pans and a chilled storage cabinet below. The pizza prep version uses a granite or marble worktop for rolling out dough. A pizza prep counter fridge gives a pizzeria everything it needs in a single unit. For salad sections and sandwich stations, a saladette does the same job with gastronorm wells on top for prepped ingredients.
Merchandiser fridge: convenience and retail
A merchandiser fridge is built for high-volume retail display. Heavy-duty hinges, larger compressors and reinforced shelving cope with hundreds of customer openings a day. They suit forecourts, convenience stores and any site where the fridge is part of the customer journey rather than the kitchen.
How to choose the right size
Sizing comes down to two questions: how much chilled stock do you hold at peak, and how often is it delivered? A site taking weekly deliveries needs more capacity than one taking drops every other day.
The table below maps fridge capacity to gastronorm trays and a rough guide to covers per service. Treat the covers figure as a starting point. Menus with lots of fresh prep or chilled desserts will need more.
| Capacity (litres) | 1/1 GN trays | Indicative covers per service | Typical use |
|---|---|---|---|
| 100 to 200 | 4 to 6 | 30 to 60 | Coffee shop, small bar, food truck |
| 300 to 500 | 8 to 14 | 60 to 130 | Café, gastropub, deli |
| 600 to 800 | 16 to 22 | 130 to 220 | Mid-size restaurant, takeaway |
| 1,000 to 1,400 | 28 to 36 | 220 to 400 | Hotel, banqueting, busy restaurant |
| 1,500+ | 40+ | 400+ | Production kitchen, central caterer |
A practical rule: buy 20 percent more capacity than you think you need today. Menus grow, prep schedules slip, and a fridge running half-empty costs no more to run than one that is full.
Solid door vs glass door
The door choice usually maps to where the fridge sits in your venue. Both formats have their place.
A solid door fridge holds temperature better and uses less energy. There is no thermal loss through the glass, the seal is simpler, and the compressor cycles less often. Solid doors are the right choice for back-of-house storage where nobody needs to see what is inside. Most upright kitchen fridges, undercounter fridges and bench fridges come with solid stainless steel doors.
A glass door fridge sells the stock for you. Customers can see the drinks, the cakes or the sandwiches without opening the door, so impulse sales rise and unnecessary door openings fall. The trade-off is roughly 15 to 20 percent higher energy use compared with the equivalent solid door model, and a slightly higher purchase price. Glass doors suit cafés, bars, delis, forecourts and any site where the fridge faces the customer.
Ventilated vs static cooling
The cooling method affects food quality, temperature evenness and how often you defrost. There are two main approaches in commercial fridges.
Static cooling relies on natural air movement. The compressor cycles to hold temperature, cold air sinks and warmer air rises. It is the quietest option and the gentlest on uncovered product, but the bottom of the cabinet runs noticeably colder than the top. Static cooling suits chest-style fridges and lower-volume sites where the fridge is not opened often.
Ventilated (fan-assisted) cooling circulates cold air with a small internal fan. Temperature is even across every shelf, recovery after a door opening is faster, and the unit holds steady even in a hot kitchen. The fan can dry uncovered product slightly, so wrap items properly. For any busy kitchen with constant door openings, ventilated cooling is the right choice and is now standard on most commercial uprights.
Energy ratings and running costs
Commercial fridges run all day, every day. Even a small difference in efficiency adds up over a year. UK appliances use the A to G energy label scale, and the gap between an A and a G unit on a 600 litre fridge can be more than £180 a year on a UK commercial tariff.
The table below gives indicative running costs for a 600 litre upright fridge at a UK commercial electricity rate of around 28p per kWh. Your actual cost will vary with rate, ambient temperature and door discipline.
| Energy rating | Estimated kWh per year | Indicative annual cost (£) |
|---|---|---|
| A | 500 to 700 | £140 to £195 |
| B | 700 to 900 | £195 to £250 |
| C | 900 to 1,100 | £250 to £305 |
| D | 1,100 to 1,400 | £305 to £390 |
| E to G | 1,400 to 2,000 | £390 to £560 |
A few practical points. Position matters. A fridge next to an oven or in direct sunlight will use 15 to 25 percent more energy than the same unit in a cooler corner. Door seals matter too. A damaged gasket can add £50 to £100 a year on its own, so check seals every quarter. And keep the condenser clean. A clogged condenser is the single most common cause of high bills and early compressor failure.
Modern units now use R290 hydrocarbon refrigerant, which uses around 15 percent less energy than older refrigerants and has a lower environmental impact. If you are upgrading from a unit more than ten years old, the energy saving alone usually pays back the new fridge within three to five years.
Commercial fridge regulations (UK)
UK food law requires chilled food to be stored at 8°C or below. Most commercial fridges are factory set to between 2 and 4°C, giving you a sensible safety margin. Some operators set their fridges colder for fish, dairy or delicate desserts.
Under HACCP, you are expected to monitor and record fridge temperatures regularly, usually twice a day. A digital thermostat with a clear external display makes this quick. Many modern units include an alarm if the internal temperature rises above a set point, which protects stock overnight and gives you an audit trail for environmental health visits.
Other points worth knowing. Chilled deliveries should arrive at 8°C or colder and go straight into storage. Hot food being chilled for later service should be cooled rapidly first, ideally in a blast chiller, before it goes into the holding fridge. And a well-stocked fridge at temperature will hold cold for several hours during a power cut, so keep the door shut and call your supplier.
How much does a commercial fridge cost?

| Saladette | 240 to 400 litres | £950 to £2,200 |
What pushes the price up: stainless steel interior, R290 refrigerant, digital controls with HACCP logging, self-closing doors, and triple-glazed glass on display models. What pushes it down: white-painted exteriors, static cooling and basic mechanical thermostats.
Finance is widely available on commercial refrigeration. Lease and lease-purchase deals spread the cost over 36 to 60 months and let you treat the fridge as an operating cost rather than capital outlay. Most VAT-registered businesses can also recover the VAT on the purchase.
Frequently asked questions
What temperature should a commercial fridge run at?
A commercial fridge should run between 2 and 5°C. UK food law requires chilled food to be held at 8°C or below, so the working range of 2 to 5°C gives a safety margin even if the door is opened often. Some operators set their fridges to 1°C for fish or delicate dairy. Anything above 5°C risks food safety and shortens shelf life.
How long does a commercial fridge last?
A well-maintained commercial fridge should last 10 to 15 years. The compressor is the part most likely to fail, and condenser cleanliness has the biggest impact on its lifespan. Clean the condenser every three months, check door seals quarterly, and service the unit annually. Cheaper units may only manage 6 to 8 years before needing replacement.
Glass door vs solid door fridge, which is best?
It depends on where the fridge sits. A solid door fridge is more energy-efficient and holds temperature better, which makes it the right choice for back-of-house kitchen storage. A glass door fridge lets customers see the stock and drives impulse sales, which makes it the right choice for any fridge facing the customer in a café, bar, deli or shop.
Can you use a commercial fridge at home?
Technically yes, but it rarely makes sense. Commercial fridges are louder, more expensive to buy, and use more electricity than a domestic equivalent of similar capacity. They are built for hot kitchens with constant use, neither of which apply at home. For domestic settings, a standard A-rated home fridge will be cheaper to buy and cheaper to run.
What size fridge do I need for a restaurant?
Most independent restaurants need at least 600 to 1,000 litres of chilled storage. A typical setup is a 1,200 litre double-door upright for bulk storage, plus a 280 litre undercounter or bench fridge on the prep line. Volumes scale up from there for hotels, banqueting and high-cover sites. As a rough rule, allow 4 litres of fridge capacity per cover served per day.
