What Are The Top Requirements for a Commercial Kitchen?

Setting up a commercial kitchen is one of the most significant - yet rewarding - steps of bringing a new food business to life. Whether you are a seasoned professional, someone who is looking to transition from working someone else’s line to launching your own kitchen, or you are embarking on an entirely fresh business venture, the fundamental planning remains identical. It is a thorough and methodical journey that is absolutely vital to get correct from the very beginning.

The decisions made here will shape how the commercial kitchen performs for years to come, so there is a lot to consider beforehand. The good news is that a functioning, profitable hospitality business is not beyond reach, with the right guidance. A well-planned commercial kitchen set up is about more than simply meeting regulation requirements, but is a chance to make the ideal setting for kitchen staff and chefs to do their best work, regardless of how busy the service may be. 

It should support your team, run efficiently even under pressure and be tough enough to handle years of use, and that is exactly what this guide is here to help you with. 

Start with the layout, not the equipment 

It is easy to get excited about shiny new catering equipment, the combination ovens, the walk-in fridges, the super efficient dishwashers, but none of them will work efficiently if the space that they occupy is poorly designed around an actual working kitchen. Start with the layout first, then build upon it. 

A good commercial kitchen set up should be based on how it is used in the busiest of times, and for this we need zones:

Goods receiving: a dedicated area for deliveries to be checked and logged before anything enters storage

Food storage: separate provision for dry goods, refrigerated items, and frozen produce

Preparation: raw ingredient prep kept entirely away from cooked food areas to eliminate cross-contamination risk

Cooking: the main cookline, designed around the menu and the volume of covers being served

Warewashing: far enough from food prep that dirty crockery never crosses a clean pass 

This zoning is more than just common sense, it’s a legal requirement. Under the Food Safety Act 1990, your kitchen needs to be ruled by a Food Safety Management System built on the principles of Hazard Analysis and Critical Control Points (HACCP). 

It sounds strikingly obvious when you say it out loud, but so many poorly designed kitchens fail simply because they forget about the usability of the space. If your chefs have to dodge kitchen porters carrying dirty dishes just to grab an onion, the layout is broken. A linear or island configuration keeps teams in their own lanes and stops a busy service from becoming overwhelmed and chaotic.

What equipment is required in a commercial kitchen set up?

Heavy duty cooking appliances are the real heart of a commercial kitchen set up. The most important parts fall under two categories: prepping and cooking the food, and storing/cooling the food. 

Cooking

Combination ovens are a real favourite among UK chefs and caterers, because they allow precision when it comes to temperature control, and consistency across multiple racks. They also give you the ability to steam and roast and bake all at the same time. For a busy kitchen, investing in something that allows you to do all three can be nothing short of transformative.

Depending on the menu, the cookline will need to be customised to what it needs, not what other kitchens have. This could look like convection ovens, heavy duty gas or induction ranges, griddles, fryers or even specialised pizza ovens. 

One thing that cannot be skipped: any gas-fired equipment must be installed and signed off by a Gas Safe registered engineer with the correct COMCAT qualifications. High quality providers of commercial catering equipment will do this as standard, but it is always worth checking.

Refrigeration

Refrigeration deserves just as much thought. UK food safety law requires perishable ingredients to be kept below 5°C, and commercial units are built to maintain that even when the doors are constantly opening and closing throughout a hectic service. Most kitchens need a combination of upright fridges, counter fridges for the prep line, and a walk-in cold room. Counter fridges are particularly useful because they double as prep surfaces, a tiny thing, but it can make a real difference when the kitchen is running at full tilt.

Blast chillers tend to surprise people who haven't encountered them before. UK regulations require hot food to be cooled from 70°C to 3°C within 90 minutes before it goes into standard cold storage. A blast chiller does this easily. Without one, that timeline is almost impossible to hit safely, and the consequences of getting it wrong go well beyond a bad hygiene rating.

The unglamorous essentials

Warewashing: Pot washing may be unglamorous, but it matters enormously. A commercial kitchen without a proper system in place will grind to a halt shockingly quickly. Domestic dishwashers run cycles of forty minutes or more, and with a commercial under-counter machine you can clean hundreds of plates and cups an hour. For larger kitchens there are pass-through or conveyor dishwashers that can handle thousands per service. 

Surfaces: When we think of a top of the line commercial kitchen set up, we think of sparking masses of stainless steel. This is no accident. It is the industry standard for counters and shelving because it is non-porous, does not harbour bacteria and is easy to clean. It can also take the punishment of industrial cleaning chemicals without degrading. 

Dedicated handwashing stations: these come in a surprising array of styles, such as sensor or knee pedal operated, depending on the specific requirements of the kitchen. But they have to be separate from the prep sinks and they are not a nice-to-have: they are a minimum legal requirement.

Ventilation: this is another one that catches new operators off guard. A heavy cooking line produces heat, smoke, and airborne grease in volumes that are hard to imagine until you have experienced it. A proper extraction system is required by law under the Health and Safety at Work Act 1974, and the entire system needs professional deep cleaning at least annually to satisfy TR19 grease hygiene standards and keep your insurer happy.

Storage: You’ll need plenty of storage, and in a variety of set ups too. Dry goods will need cool, ventilated spaces off of the floor. Cleaning chemicals need to be stored in their own, separate locked cupboard, away from the food. In another type of storage, there are grease traps to think about too. These are legally required to stop fats and oils from entering the sewage system. 

All of these considerations may seem minor on the surface, but during a busy period, they will serve your kitchen just as much as the latest cooker or refrigeration system. It helps to see the whole picture when designing a commercial kitchen set up.

Getting it right from the start 

Here is the honest truth: understanding what a commercial kitchen needs and what equipment is required in a commercial kitchen is just the beginning. Translating that understanding into a space that actually works, that is: one that passes inspection, sets your team up for success, and serves food efficiently under real pressure, well that is a different challenge entirely.

Here at Commercial Catering Contracts, we have been achieving exactly this for over 30 years, working alongside cafes and restaurants, schools and hotels and every other imaginable location that requires a workable commercial kitchen set up. We design, supply, install and maintain kitchens that are made to be used, that are built around real deadlines and real menus, but most importantly: real budgets. If you’re in the early stages of planning and need answers to what equipment is required in a commercial kitchen, then we are here to help. Just get in touch.

FAQs

Do I need planning permission to open a commercial kitchen?

Not always, but often yes. If you are changing the use of a building (from retail to food service, for instance) you will typically need a change of use application from your local planning authority. This is entirely separate from registering as a food business with environmental health, which also needs to happen at least 28 days before you open. Getting both sorted early saves a lot of stress later.

What hygiene rating will my commercial kitchen get?

That depends entirely on the inspection. Environmental health officers look at the physical condition of the premises, the food safety management systems in place, and how confident they are that standards will be maintained day to day. A well-designed kitchen with proper zoning, the right equipment, and well-trained staff puts any new business in the best possible position. A five-star rating is achievable from day one, but it does require the groundwork to be done properly.

Can an existing domestic or unused commercial space be converted into a commercial kitchen?

Yes, and it is actually more common than you may think. Empty retail spaces, old pub kitchens, even large domestic spaces have been turned into fully functioning professional kitchens. As long as all the critical questions around whether the current infrastructure can be addressed, such as electrics, gas supply, ventilation and drainage, can support  what equipment is required in a commercial kitchen, then you’re already half way there. After that you’ll need to address the food safety requirements, and this can be helped along by an honest assessment from an experienced kitchen designer.
