Why Kitchen extraction matters
If you’re planning to open a restaurant, café, pub or takeaway, your mind is probably full of menus, suppliers and interior design ideas. One part of the process that often gets overlooked is kitchen extraction. It may not be the most exciting detail, but it is one of the most important.
The right extraction system keeps your kitchen safe and comfortable, helps you stay compliant with regulations, and prevents issues with neighbours. Many new owners only realise how complex it can be after they’ve signed a lease, and by then the costs and restrictions can come as a shock. By understanding your options early, you can avoid common pitfalls and start your business on the right footing.
Do Your Homework before starting out
Once you understand why extraction is so important, the next step is to prepare properly. Think of this stage as building the foundations for your business.
Start by checking what permissions you’ll need for the type of cooking you plan to do. Requirements can vary between local authorities, so it pays to get clarity early. Next, speak to specialists who can assess whether your chosen property is suitable for a commercial kitchen. They can often spot potential issues that might not be obvious to you.
Finally, map out a budget that reflects the real cost of extraction and ventilation. Many first-time owners underestimate this, and it can quickly become the single biggest expense in a kitchen fit-out. By doing this groundwork now, you set yourself up for a much smoother path when it comes to planning and approvals.
The 5-Step rule for assessing your premises
Once you have done some initial research, the next stage is to look closely at your chosen premises. Here are five key things to consider before you commit:
1. Look at the surroundings
Think about what’s around the site. If there are homes or flats nearby, noise and odour may be more tightly controlled, which could limit your options.
2. Think about extraction and fresh air
Every commercial kitchen needs to remove heat, smoke and odour, but also bring in clean air to replace what’s taken out. Getting this balance wrong makes kitchens uncomfortable and can lead to compliance issues.
3. Check the essential services
Ask what utilities are already available, electricity, gas and water, and whether they are suitable for the type of cooking you plan to do.
4. Consider the potential for upgrades
If the current supplies are not enough, can they be upgraded easily? For example, does the gas supply have the capacity to run multiple appliances at once?
5. Gather quotes and budget properly
Finally, get realistic quotations for the work needed. Many first-time owners underestimate costs at this stage, so building an accurate budget now will help avoid nasty surprises later.
Understanding Extraction Requirements
The exact extraction system you will need depends on both the design of your premises and the requirements of your local authority. To comply with regulations, a commercial kitchen system should:
-
Remove airborne contaminants such as grease, smoke, steam and odour. This usually involves a canopy, ductwork and a fan system.
-
Introduce fresh air at a safe and comfortable rate for staff. The general rule is that the system should replace the air being removed, so the kitchen is balanced rather than creating a vacuum.
-
Control noise and vibration so that it does not create a nuisance for neighbours or other businesses in the same building.
-
Meet DEFRA and Building Regulations guidance on discharge points, filtration and air quality.
Local authorities may also have additional requirements. For example, some will specify how high a flue must be above roof level or what kind of filters must be used to control odour. This means that what is acceptable in one council area might not be approved in another.
If you are planning a new hospitality venture, it is always worth contacting the planning or environmental health team before you commit to a lease. They can tell you what is possible on a particular site and highlight any restrictions.

What to Consider When Planning Extraction
When planning your extraction system, the details matter. Where can the outlets go, and will they affect your neighbours? How will you manage fan noise? What filters or systems will you use to deal with grease and odour? And crucially, where will your fresh air supply come from?
These are questions your installer will help you answer, but it’s useful to keep them in mind when comparing different premises or budgeting for fit-out costs.
Key Considerations
When reviewing your options, consider:
- Outlet location: where can ducts or flues be safely positioned?
- Noise levels: fans must not disturb neighbours.
- Smoke and odour control: filters and discharge points matter.
- Fresh air input: balance extracted air with safe replacement air.
✅ Mini-checklist:
- Have I planned where the ducting will run?
- Have I considered noise insulation?
- Do I know how the odour will be managed?
- Where will the fresh air come from?
When External Extraction Isn’t Possible
Not every premises allows you to run ducting outside, a common issue for high street units, shared buildings, and listed properties. In these cases, a recirculation or reflow system may be the only viable option.
These systems work much like an advanced cooker hood: air is pulled through a series of filters that strip out grease, smoke, and odour before releasing the cleaned air back into the kitchen. Because the air stays warm, air conditioning is usually required to keep the environment safe and comfortable.
It’s worth noting that recirculation systems can be more costly to run and maintain, as filters need regular replacement. They also aren’t suitable for every type of cooking — heavy frying or chargrilling, for example, may still require full external extraction.
That said, where planning restrictions leave you with no other choice, these systems can provide a compliant, workable solution and allow your business to operate in otherwise challenging locations.
Common Pitfalls to Avoid
It’s easy to get caught out with kitchen extraction, especially if it’s your first hospitality venture. Here are the issues that most often trip people up — and how to avoid them:
1. Choosing a property before checking ventilation feasibility
Many business owners fall in love with a site only to discover it can’t accommodate the ducting or fans they need. Always assess extraction potential before signing a lease.
2. Underestimating the true cost of installation
Extraction is one of the most expensive parts of a kitchen fit-out. A rough budget without professional quotes can leave you short when it matters most. Get detailed costs early and factor them into your business plan.
3. Leaving planning applications until the last minute
Ventilation systems often need planning consent, especially in built-up areas. Applications can take weeks or even months to be approved, so start the process as soon as you can.
4. Ignoring the impact on neighbours
Noise, odour, and visual appearance are common sources of complaints. Even if your system is compliant, unhappy neighbours can delay approvals or cause ongoing issues. Involve your installer and local authority early to minimise disruption.
Who’s Involved?
Several different authorities have a say in your kitchen extraction, and knowing who does what can save you time and frustration.
-
Planning Department
If your system involves external ducting or fans, you’ll usually need planning approval. They’ll look at how it affects the building’s appearance, as well as the impact on nearby homes or businesses. It’s best to engage them early, especially if your premises are in a conservation area or high street location. -
Building Control
Building control officers make sure your extraction system meets health and safety standards. They’re focused on whether the system works properly and provides enough clean air for staff. They’ll usually want to review technical specifications before giving the green light. -
Environmental Health
Once you’re trading, environmental health officers are the ones who respond to complaints about noise, smoke, or odour. Even if your system is technically compliant, persistent complaints can trigger investigations. That’s why it pays to get the design right from the start.
Tip: Don’t wait until after you’ve installed equipment to involve these authorities. Engaging them early avoids costly rework and gives you confidence your system will pass inspections.
Final Thoughts
Commercial kitchen extraction can feel like a minefield when you’re just starting out, but it doesn’t have to be. The key is to think about it early, seek advice from people who understand the regulations, and budget realistically. With the right setup, you’ll not only stay compliant but also create a safer, more pleasant environment for your team and customers.

Glossary of key terms
If you are new to commercial kitchens, some of the technical language around extraction can feel overwhelming. This quick glossary will help you make sense of the terms you are most likely to come across:
-
Extraction system
The complete setup that removes hot, smoky or greasy air from the kitchen. It usually includes a canopy, ductwork, filters and fans. -
Fresh air input (or make-up air)
The supply of clean air brought into the kitchen to replace what has been extracted. Without it, kitchens quickly become stuffy and unsafe. -
Canopy
The hood fitted above cookers, fryers and grills. Its job is to capture smoke, steam and grease so they can be carried away through the extraction system. -
Ductwork
The metal pipes or channels that carry contaminated air from the canopy to the outside of the building, or through filters in a recirculation system. -
Discharge point
The outlet where extracted air is released. Councils often set rules on where this can be positioned and how high it must be. -
Recirculation system
An alternative setup that filters and cleans air before releasing it back into the kitchen. Often used where external ducting is not possible.
