The Different Types of Commercial Refrigeration (And Where Each One Fits)
Not all fridges do the same job. And the type you need depends less on what's popular and more on your actual kitchen - the layout, how many covers you're doing, what you're storing. So let's go through them.
Upright Fridges
The workhorse of most commercial kitchens. Upright fridges offer the most storage capacity per square foot of floor space, and they're easy to organise with adjustable shelving. You'll find single-door, double-door, and even triple-door models depending on how much space you've got.
Best for: restaurants, hotels, and any kitchen doing serious volume. If you're storing large quantities of prep and need quick access during service, an upright is probably where you should start.
We've written a detailed breakdown of what to look for in modern commercial upright fridges if you want to get into the specifics.
Undercounter Fridges
These sit beneath your worktop and keep ingredients within arm's reach of your prep station. They won't hold as much as an upright, but that's not the point. They're about speed and convenience during service.
Best for: cafes, bars, small kitchens, or as a secondary unit alongside a larger fridge. If your chefs are constantly walking to the other side of the kitchen for ingredients, an undercounter unit at their station solves that.
Prep Counters (Refrigerated Workstations)
Part fridge, part work surface. These combine chilled storage underneath with a food-grade stainless steel top for prep. Some come with saladette-style ingredient wells - pizza shops and sandwich bars will know exactly what we mean.
Best for: pizza kitchens, sandwich shops, salad bars, and anywhere that needs cold ingredients accessible during assembly.
Display Fridges
If customers need to see what you're selling, you need display refrigeration. These come in countertop, upright, and multi-deck formats. They look great, but remember: every time someone opens a display case (or it's an open-front model), the compressor works harder.
Best for: cafes, delis, bakeries, and any business where visual merchandising drives sales.
Commercial Freezers
Same logic as fridges, but for long-term frozen storage. Chest freezers win on bulk storage and energy efficiency - the lid opens upward so cold air doesn't fall out every time you open it. Upright freezers are easier to organise and access quickly. Plenty of kitchens end up with one of each.
Best for: anywhere that batch-preps, buys in bulk, or relies on frozen ingredients as part of the supply chain.
Walk-In Cold Rooms
For operations that have outgrown standalone commercial refrigeration units. Walk-in cold rooms give you the most storage but require dedicated floor space, professional installation, and proper ventilation. They're a serious investment - but for high-volume operations, they pay for themselves through better stock management.
Best for: large restaurants, hotels, catering companies, and wholesale operations.
How to Size Your Commercial Refrigeration
This is where most people go wrong - and we say that from experience. Sizing issues are one of the most common questions we get from customers setting up their first commercial kitchen, and they're one of the top reasons people end up replacing a fridge within two years of buying it. Buy too small and you're cramming food in, blocking airflow, and watching temperatures climb. Buy too large and you're paying to cool empty space.
Work Backwards From Your Menu
Start with what you store, not what looks impressive in a showroom. Ask yourself:
-
How many covers do you do per service?
-
What's your delivery schedule? (Daily deliveries mean less storage needed)
-
How much prep do you do in advance?
-
Do you have seasonal peaks that require extra capacity?
The 75% Rule
Never fill a commercial fridge beyond 75% capacity. Airflow is critical - if cold air can't circulate around your stock, temperatures become uneven and your compressor runs harder to compensate. That costs you energy and shortens the unit's lifespan.
Measure Your Space First
Obvious, but frequently overlooked. Measure not just the floor space but also:
-
Door swing clearance (a 90-degree opening needs more room than you'd think)
-
Ventilation gaps around the unit (most need 50-150mm clearance on sides and rear)
-
Height, including any overhead shelving or extraction hoods
-
The route from your delivery entrance to the kitchen - will the fridge actually fit through the doors?

Fan-Assisted vs Static Cooling: Which Do You Need?
You'll see these terms on almost every product listing. Worth understanding what they actually mean for your kitchen, because the difference isn't trivial.
Fan-Assisted (Forced Air) Cooling
A fan circulates cold air throughout the cabinet, creating even temperatures on every shelf. Recovery time after door openings is faster, which matters in a busy kitchen where the fridge door is opening every few minutes during service.
The trade-off: Fan-assisted units are louder and use slightly more energy. They can also dry out uncovered food faster.
Choose this if: You're running a busy kitchen with frequent door openings and need consistent temperatures across all shelves.
Static Cooling
Cold air circulates naturally without a fan. The unit runs quieter and uses less energy, but temperatures can vary between shelves (colder at the bottom, warmer at the top). Recovery after door openings is slower.
Choose this if: You're running a lower-volume operation, the fridge isn't being opened constantly, or you need a quiet unit in a front-of-house area.
For most commercial kitchens doing regular service, fan-assisted is the safer bet. Static works well for back-of-house storage that isn't accessed as frequently.
Understanding UK Food Safety Requirements
Right, this bit isn't optional. Get temperature control wrong and you're risking a poor food hygiene rating - or worse, making someone ill.
The Legal Temperature Limit
Under the Food Safety (Temperature Control) Regulations 1995, chilled food must be stored at 8°C or below in England, Wales, and Northern Ireland. That's the legal maximum.
What You Should Actually Aim For
The Food Standards Agency recommends setting your fridge to 5°C or below to allow for temperature fluctuations when the door opens. High-risk foods like raw meat, seafood, and dairy should be stored between 1°C and 2°C where possible.
The critical thing to understand: the law refers to the temperature of the food itself, not the air temperature inside the fridge. If your fridge is set to 5°C but it's packed full with no airflow, the food in the middle might be sitting at 9°C. That's a compliance failure.
Temperature Monitoring
Modern commercial fridges come with digital temperature displays, and many now offer data logging that records temperatures throughout the day. This is genuinely useful - not just for compliance, but because it gives you an early warning if a unit starts struggling before it fails completely.
Some higher-end models even send alerts to your phone if the temperature rises above a set threshold. For operations where a fridge failure could mean hundreds of pounds in wasted stock, that's worth considering.
Energy Ratings and Running Costs
Your fridge never takes a day off. It runs 24 hours a day, every single day of the year - and that makes it one of the biggest energy draws in your kitchen. Choosing an efficient model doesn't just feel responsible. It genuinely pays for itself.
How UK Energy Labels Work
Commercial refrigeration in the UK follows Ecodesign and Energy Labelling Regulations. Units are rated on an A to G scale, with A being the most efficient. When comparing models, look beyond the sticker price - a cheaper unit with a poor energy rating could cost you significantly more over its lifetime in electricity.
The Refrigerant Transition
This is something a lot of buyers aren't aware of yet, but it matters. The UK (following F-Gas Regulation requirements) is phasing out high-GWP (Global Warming Potential) refrigerants like R404A and R410A. Newer units increasingly use R290 (propane) and R600a, which are better for the environment and more energy efficient.
Why should you care? If you buy a unit running on an older refrigerant, servicing and recharging it will get more expensive over time as those refrigerants become harder to source. Buying a unit with a modern, low-GWP refrigerant is a smarter long-term investment.
If energy costs are a major concern for your business, we've put together a detailed guide on energy-efficient catering equipment that goes deeper on this.
Practical Ways to Keep Running Costs Down
Even with an efficient unit, how you use it matters. A lot, actually.
-
Keep the door closed as much as possible. Sounds obvious. Then watch a busy kitchen on a Saturday night and count the door opens - it's eye-opening.
-
Don't put hot food straight in. Let it cool first. Shoving a hot tray of bolognese into the fridge forces the compressor into overdrive and raises the temperature of everything around it.
-
Clean the condenser coils. Monthly. This is the single biggest thing you can do to keep energy costs down. Dust and grease build-up makes the compressor work significantly harder.
-
Check door seals regularly. A worn gasket is basically a slow leak of cold air (and your money).
-
Keep the unit away from ovens, fryers, and direct sunlight. Seems obvious, but kitchen layouts sometimes force compromises here - at least maximise the gap where you can.
What to Look for When Comparing Models
You've figured out the type. You've measured the space. Now you're looking at actual units - and they all sort of look the same. Here's what to pay attention to.
Construction Quality
Stainless steel interior and exterior is standard for commercial-grade units, and for good reason. It's durable, easy to clean, and doesn't corrode. Be cautious with units that use cheaper materials on the interior - they won't hold up to the daily wear of a working kitchen.
Shelving and Layout
Adjustable shelving matters more than you'd think. Gastronorm-compatible shelves (GN 1/1 or GN 2/1) make organisation much easier and are standard in professional kitchens. Check how many shelves are included and whether you can reconfigure them to fit tall containers or stacked trays.
Door Type and Design
Solid doors retain cold better. Glass doors let you see contents without opening (useful for reducing unnecessary door openings). Self-closing doors are worth having in a busy kitchen - you'd be surprised how often a fridge gets left ajar during a rush.
Reversible doors are handy if your kitchen layout means the fridge needs to open from a specific side.
Noise Level
Fan-assisted units with powerful compressors can be loud. If the fridge is going anywhere near customers - a cafe counter, a bar, a front-of-house display area - check the decibel rating. Anything under 45dB is generally considered acceptable for customer-facing areas.
Warranty and After-Sales Support
A two-year warranty is fairly standard, but what it covers varies. Check whether the compressor has a separate (often longer) warranty. And think about after-sales support: if it breaks down on a Friday afternoon in August, how quickly can you get someone out?
Buying from a UK-based supplier means easier access to spare parts and support. We've seen too many cases where customers bought from overseas sellers and then couldn't get a replacement gasket or thermostat when they needed one urgently. We stock units from brands like Quattro, Contender, and Gastrotek - all with UK-based support channels and spare parts availability.
Specifications and features vary between models and brands. Always check individual product details and ensure any unit you're considering meets the specific requirements of your kitchen and local regulations.
Gastronorm Compatibility: Why It Matters
If you've worked in a commercial kitchen, you know gastronorm pans. They're the standard sizing system used across professional foodservice - from prep to storage to serving.
A fridge that's GN 1/1 compatible means standard gastronorm pans (530mm x 325mm) fit directly onto the shelves without adapters or wasted space. Larger units may be GN 2/1 compatible (530mm x 650mm), fitting wider pans used in higher-volume operations.
Why does this matter? Because it directly affects how efficiently you can use the space. Non-gastronorm fridges might technically have the same cubic capacity, but you'll waste space trying to fit standard kitchen containers into non-standard shelving.
Maintaining Your Commercial Refrigeration
The best fridge in the world won't perform if you neglect maintenance. And honestly, most maintenance isn't complicated - it just needs to actually happen. Industry data suggests that consistent preventive maintenance can extend a commercial fridge's working life by up to 30% and reduce energy costs by 5-10%. That's not a minor difference over a unit's lifetime.
Weekly Tasks
-
Wipe down interior surfaces and shelves
-
Check door seals for wear, cracking, or food debris
-
Verify the temperature display matches an independent thermometer
-
Clear any ice build-up in freezer units
Monthly Tasks
-
Clean condenser coils (dust and grease build-up is the number one cause of compressor strain)
-
Check drain channels are clear
-
Inspect hinges and door closers
-
Review temperature logs for any unusual patterns
Twice-Yearly (Professional Service)
-
Full refrigerant check
-
Compressor inspection
-
Electrical connections check
-
Fan motor and evaporator inspection
Consistent maintenance can extend a commercial fridge's lifespan by years. We've covered this in more detail in our guide on how to extend the lifespan of your catering equipment.
How Much Should You Expect to Spend?
Pricing varies widely depending on type, size, brand, and features. These are approximate ranges based on what we typically see across the market - your actual cost will depend on the specific unit and features you need:
-
Undercounter fridges: From around £300-£800
-
Single-door upright fridges: From around £500-£1,500
-
Double-door upright fridges: From around £800-£2,500
-
Prep counters: From around £600-£2,000
-
Display fridges: From around £400-£2,000+
-
Commercial freezers: From around £400-£2,000+
Remember: the purchase price is only part of the cost. Factor in energy consumption over 5-7 years, maintenance costs, and the potential cost of a breakdown (lost stock, emergency repairs, disrupted service).
If budget is tight, flexible payment options help. We offer Pay in 3 and leasing arrangements that spread the cost - which can make a better, more energy-efficient unit affordable rather than forcing you to buy the cheapest option upfront.
Frequently Asked Questions
What temperature should a commercial fridge be set to?
The legal maximum for storing chilled food in the UK is 8°C, but the FSA recommends 5°C or below. For raw meat and seafood, aim for 1-2°C. Always monitor food temperatures, not just the air temperature reading on the display.
How long do commercial fridges typically last?
With proper maintenance, a quality commercial fridge should last 10-15 years. The compressor is usually the first major component to need attention, typically around the 7-10 year mark. Regular coil cleaning and gasket replacement are the two most impactful things you can do to extend lifespan.
What size commercial fridge do I need for my restaurant?
It depends on your covers, menu, and delivery frequency. A general rule: a 600-litre upright suits most restaurants doing 50-80 covers per service. Higher volume operations may need 1,200+ litres or multiple units. Never fill beyond 75% capacity to maintain proper airflow.
Is fan-assisted or static cooling better?
For busy commercial kitchens, fan-assisted is generally better - it recovers temperature faster after door openings and maintains more even temperatures. Static cooling is fine for lower-volume use or front-of-house areas where noise is a concern.
Should I buy or lease commercial refrigeration?
Honestly? Neither is always better. Buying outright costs less over the lifetime of the unit, but it ties up cash. Leasing keeps your cash flow healthier and sometimes includes maintenance - which is a genuine perk. If you're just starting out or growing fast, leasing often makes more practical sense. If you've got the capital and plan to use the unit for 10+ years, buying usually wins on total cost.
Making the Right Choice
There's no single "best" piece of commercial refrigeration. There's just the right one for your kitchen, your menu, and what you can actually afford - both upfront and in running costs over the next several years.
Start with what you need to store. Measure everything. Think beyond the price tag to what that unit will cost you in electricity over five or seven years. And once it's installed, actually maintain it. Seriously. A well-maintained £800 fridge will outlast and outperform a neglected one that cost double.
