How to choose the right commercial freezer for UK businesses: The ultimate guide

What's more they’re easy to operate. You can stack products from above without the need to organise stock around shelf heights or spend extra time on product presentation, this suits businesses handling large volumes of frozen goods on a regular basis.

Before your customer settles on a specific model, there’s also a handful of practical points worth discussing together.

Footprint is a big one, both in terms of floor space and the room needed to lift the lid, something which can be overlooked. Solid lids offer better insulation and are usually the right call for storage, while glass lids are a good option where businesses want their customers to see the product inside.

You also need to check there's enough clearance around the unit for deliveries to be loaded in, particularly in smaller back-of-house spaces where every square inch counts.

Counter freezers

Counter freezers sit at working height, usually under a food prep surface or built into a run of commercial kitchen equipment. Providing frozen storage for customers in a convenient spot that doesn't eat into valuable floor space.

Many units are available as either single units with solid doors, or as part of a longer configuration with multiple sections tailored to the layout of a specific kitchen.

These units are often found in cafés, food-to-go outlets, quick-service restaurants and prep kitchens. Essentially anywhere where staff work at a fast pace and need stock within easy reach. In these environments, keeping popular items in close proximity can improve how the kitchen runs, vastly improving efficiency and customer experience.

In short, counter freezers make it easy to access stock. Because the freezer cabinet is situated below the counter, it frees up valuable worktop space above it for prep work, without needing the clearance that a full-height freezer would demand.

Many models are designed to integrate neatly into existing counter runs, so they can slot into a customer’s setup without too much planning. And with stock stored right next to where it’s being used, staff don't have to waste valuable time moving between stations, giving them more time getting food and drink to customers.

When you’re advising customers on which counter freezer is best for them, ventilation is key. With these units often being built into tight runs of equipment with restricted airflow, they need clearance both underneath and around the unit.

Solid doors are a great option for cabinet efficiency, meanwhile glass doors allow staff to check stock levels quickly, which is very useful the fast-paced world of commercial kitchens. You'll also want to weigh up capacity vs footprint, since counter freezers trade some storage volume for their compact design.

Low-temperature chest freezers

Ultra-low chest freezers are built for a specific job. Whereas a standard commercial freezer holds product safely at around -18°C, these units are engineered to reach and maintain temperatures as low as -45°C. They use a combination of stronger compressors, thicker insulation and components designed to cope with the additional strain of running at colder temperatures.

Food producers who are selling products which need rapid, deep freezing to preserve texture and quality rely on these units, along with ice cream suppliers who need to harden their products before they’re ready for distribution. You’ll also find them in research and lab environments, where samples and materials must be held at precise, ultra-low temperatures without the risk of drifting temperatures.

The main benefit for your customers is the ability to freeze product more swiftly and far deeper than a standard commercial freezer allows for. Once this low temperature is reached, these units hold it with impressive stability, even during frequent door opening or a demanding production schedule.

The build quality reflects the job they’re doing, with robust construction that’s designed to run continuously and at busy times for years.

When you're recommending these freezers, power requirements are a big consideration, because reaching and holding -45°C draws considerably more electricity than a standard unit.

Your customer’s site needs to be able to support that. Temperature recovery is another important consideration, particularly in production settings where the doors open frequently during the day. Plus, check access for installation early on, since these units are tend to be larger and heavier than standard freezers.

Undercounter solid door freezers

Undercounter solid door freezers do the same job as their full-height counterparts, designed to fit in a much smaller footprint. They’re designed to slot beneath worktops and counters, giving your customers frozen storage where they need it without taking up too much of their limited and valuable floor space.

High in popularity amongst cafés, bars, small commercial kitchens and food-to-go counters, these are all environments where every square foot counts. Many models are designed to integrate neatly into existing counter runs, meaning they can slot into a customer’s set-up without appearing out of place.

Like with counter freezers, ventilation needs checking carefully, as undercounter units are often boxed in on multiple sides and restricted airflow can affect their performance.

You should also measure any height restrictions on-site, too, especially if the unit needs to fit under a fixed worktop, and check the door orientation works well with the surrounding layout.

Countertop display freezers

Countertop display freezers are great options for showcasing ice creams as well as frozen treats. They sit neatly on an existing counter, often near the checkout area, with a glass door or lid that shows off everything inside.

You’ll often find these units earning their keep in cafés, kiosks, dessert shops and anywhere where customers buy on impulse. They put every product on show, which can help turn browsers into buyers far more often than a solid-lid chest freezer tucked away in a corner.

Countertop units take up very little space, which suits smaller sites with limited floorspace. They’re easy to position where shoppers can’t miss them, without getting in the way of staff serving.

Glass door display freezers

Glass door display freezers are designed to hold and showcase much more stock than a countertop unit ever could. Retailers often use them as their main frozen displays, so shoppers can browse ice creams, frozen treats or ready meals and pick items straight off the shelf.

Many places rely on these cabinets including Convenience stores, supermarkets, forecourts and leisure sites, and it's not hard to see why.

A forecourt shop might use multiple units with one for chilled snacks and cold drinks to entice drivers topping up on a hot day. Meanwhile a convenience store could use several glass door display freezers to cover everything from ready meals and desserts to meal deals and grab-and-go impulse buys.

Glass door cabinets let shoppers spot products they want fast which speeds up browsing and encourage impulse buying.

Many models also come with LED lighting built into the cabinet, which lifts the whole display and makes colours and packaging stand out under bright, even light. Plus some units have anti-condensation features to prevent the glass misting up, particularly handy in humid environments or busy stores where the doors open and close throughout the day.

Glass lid chest freezers

Glass lid chest freezers are a flexible option for any customers who want to showcase their frozen stock without committing to a large upright cabinet or multideck. The glass lid replaces the solid, insulated lid you’d find on a standard chest freezer, so shoppers can see straight into the cabinet rather than having to lift a lid to check what’s inside.

Visibility is the clear selling point here. Shoppers browsing at a glance are far more likely to make an impulse purchase than if they’d have to open a lid and rummage around inside.

Glass lid chest freezers are also easy to access and restock. They allow staff and customers alike to reach right down to the bottom without unloading half the cabinet first, which can give your customers true flexibility when it comes to merchandising. They can rearrange their stock by season, promotion or new product launch.

Some models can switch between chiller and freezer modes, making them much more versatile. For example, a trendy farm shop or kiosk with seasonal demand could run the unit as a freezer through summer for ice cream, then switch it to a chiller for drinks, dairy or chilled ready meals once the weather turns, getting the best use and selling potential out of each cabinet across the year.

Undercounter display freezers

If your customers run either a café, bar, dessert shop or food-to-go counter, or even a string of outlets undercounter display freezers are often exactly what they’re looking for.

Space is tight in these environments, so you’ll want to point your customers towards models that maximise small footprints without disrupting the flow behind the counter.

These compact units sit neatly beneath a counter or serving area, keeping ice cream and frozen desserts or snacks at the optimum temperature while putting them right in front of the customer. Unlike a standard chest freezer tucked away in a back room, these units are designed to sell as much as they store. Even sitting below counter height, the display glass keeps stock visible to anyone glancing down while they’re paying or waiting to be served, which is often enough to nudge an extra sale or two.

Many of your customers are after a unit that fits seamlessly into their existing counter run, so it’s worth checking dimensions and door orientation before recommending a specific model.

Internal LED lighting makes the display far more appealing without adding much to the running costs. However, it’s worth checking ventilation at the installation site, as some units need front or rear airflow, which affects where they can be positioned.

Essential features to compare on undercounter display freezers

Once you’ve narrowed down the type of freezer(s) your customer needs, the real value you can add comes down to helping them compare the details. These are the features worth talking through with every customer, regardless of the type of freezer(s) they’re after:

• Temperature control and consistency should be top of the list. A commercial freezer that struggles to hold a steady temperature will cost your customer money in wasted stock and low staff morale. So, it’s worth showing them how well a unit performs in busy, high-traffic environments where the door opens constantly.
• LED lighting is now standard on most quality commercial freezers. It uses far less energy than traditional fluorescent tube lighting, while making the display look brighter and more inviting.
• Build quality and materials can affect how well a freezer holds up over years of daily use, so it’s worth pointing your customers towards units with solid cabinet construction and durable finishes, especially if they’re going into a busy commercial kitchen.
• Units with castors make moving and cleaning around them far easier than trying to mop behind a static unit.
• Finally, you should factor energy efficiency and running costs into each recommendation you make, as a slightly higher upfront purchase price will often more than pay for itself over the years in lower electricity bills.

Installation, setup and maintenance

Installation isn't usually top of your customer's minds until their commercial freezer arrives on-site, so it’s worth talking them through what’s involved before finalising the sale. Getting this right from the start will save everyone a lot of time and hassle on delivery day.

You’ll need to check the floor is level and solid enough to take the weight of the unit, and that the space allows the doors or lids to open fully without hitting a wall or worktop.

Levelling and positioning affect door seals and drainage, so it’s better to use a spirit level rather than eyeballing it. A freezer that’s slightly off level can struggle to seal properly, letting warm air in and driving up running costs.

Some larger units need a dedicated circuit rather than sharing a socket with other equipment. This is one of the most common reasons a commercial freezer trips a circuit once it’s loaded with stock.

And as we’ve mentioned elsewhere in this guide, making sure there is adequate ventilation clearance is essential. Every freezer needs space around it for air to circulate. Pushing a unit tight against a wall or into an alcove can affect how efficiently it runs, sometimes shortening its lifespan in the process.

Once the unit is in place, encourage your customers to let their new freezer run empty for several hours before loading stock, to give the internal temperature time to settle at the right level.

Loading too much stock, too swiftly can overwhelm the cooling system. It’s best to build up gradually and leave gaps for air to circulate between products rather than packing everything in at once.

Well-maintained commercial freezers run more efficiently and last a lot longer, so it’s worth setting your customers up with good habits from day one. Wiping down interior surfaces, glass and door seals regularly will stop spillages and residue from affecting the unit’s performance and hygiene.

A build-up of ice on the coils forces the compressor to work harder, so encourage your customers to defrost on a regular schedule rather than waiting until performance drops.

And a yearly service from a qualified engineer will help prevent small issues, like worn seals or a struggling compressor, before they turn into a breakdown. It’s also worth pointing out that skipping routine servicing is one of the most common reasons a warranty claim gets rejected.

Common issues and troubleshooting

Even a good-quality commercial freezer will occasionally run into problems. Knowing the common causes will help you support your customers and diagnose the problem.

Temperature fluctuations are usually one of the first signs something’s not quite right. Often, the cause is as simple as a door being left open too long or too often, but your customers should check the door seals, too, since a worn seal can let warm air creep in without anyone noticing.

Frost build-up inside the cabinet is another common complaint, and it’s usually linked to humidity getting in through a door left ajar or a seal that’s no longer doing its job properly. Left unchecked, it can affect airflow and make the freezer work harder than it needs to.

Condensation on the outside of a unit is often mistaken for a fault, but it’s frequently just a sign of high humidity in the surrounding kitchen or venue. Improving ventilation in the room can make a real difference here.

Noises can also help you pinpoint what might be going wrong. A quiet hum is normal, but louder rattling or grinding usually points to something like a loose panel or a fan that needs attention.

In short, if the unit’s temperature keeps drifting, ice keeps building up despite regular defrosting, or something sounds different to normal, your customer should book a service call and let an engineer take a look, rather than waiting for the problem to sort itself out.
