Extract fan cleaning for kitchens and businesses in City of London
Is the extract fan louder than it used to be, or the airflow weaker? Tell us about it when you call 0345 646 2711, or send details by email, and you’ll get a fixed price, typically within one working day. If you have a heavily greased fan housing and hot, greasy smells near the fan, we can put it right, from discharge points, in-line fans and centrifugal fans onwards.
London kitchens are often tucked into basements or the back of a building, and the duct may run up through several floors before it discharges at the roof. For a kitchen in City of London, that usually means a longer system to clean and more access panels to plan around.
It’s worth checking any contractor’s accreditations. Ours are BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease, plus CHAS, SafeContractor and ISO 9001, with full insurance on top.

How it works
The first job on site is protection: sheeting goes over floors and surfaces close to the work. Then we make the system safe and start. The work on site takes an hour or two for one fan, longer when it’s hard to reach, and the area is cleaned down before we leave. Loading bays, visitor permits and roof access are the first things we ask about for a site in City of London.
- The fan is found and its type, access and isolation checked.
- It’s isolated so it cannot run while we work.
- Grease is scraped off the impeller blades and casing.
- The fan is degreased, taking care around the motor.
- It’s closed up, run, checked and photographed for the report.
Preparing for the visit
- Mention any sign-in, permit or induction we need
- Let us know how we reach the system, including roofs, risers and plant rooms
- Mention any parking or loading restrictions

Photos are enough for some jobs, while others need a look on site. Big or complicated sites, and systems that are hard to see in pictures, get a survey first. Either way, you get a fixed price before we start.

FAQs for City of London
Does London parking affect a job in City of London?
London parking can be tight, so details of loading bays and permits help. Where restrictions apply in the day, an evening or overnight visit normally gets round them.
Who enforces fire safety at workplaces in City of London?
Fire safety enforcement in City of London is handled by London Fire Brigade. Records of extract cleaning are a sensible thing to have ready if a fire safety officer carries out an audit.
What makes a kitchen extract fan vibrate?
Grease on the blades and housing is one of the usual causes, because it unbalances the fan. Worn bearings and motor problems are others, which our report will flag.
How do you keep the site clean during the work?
We start with protection: sheeting over floors, worktops and anything close to the work. The area is left tidy, with our waste taken away.
Which accreditations do you hold?
We are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we carry full insurance.
Does a TR19 kitchen extract clean cover the fan?
Yes. The whole system is cleaned, from the canopy to the discharge, and the fan is a key part of it, so it’s cleaned too.
How much notice should we give?
Book as early as you can for planned work, particularly if your next visit is nearly due. For emergencies, we take calls 24/7.
How long does extract fan cleaning take?
Size, access and build-up all affect it. Typically it takes a couple of hours per fan, depending on its size and the build-up.
Why it’s worth doing now in City of London
A greasy fan at the discharge can spread grease onto the roof or wall around it. It marks the area around the outlet and leaves more fuel outside, which is one more reason to keep it clean. London buildings are shared, so a fire or failure in one system can reach the neighbours above and beside you.
You won’t find a price list here, because the cost depends on the site in front of us. Call for a fixed quote, and we will talk you through it.

How we price extract fan cleaning
Your quote is based on your site. We take into account:
- Whether we need access equipment or extra panels
- Working hours and out-of-hours timing
- How many systems or sites are involved
- Travel, parking and unloading
Kitchens, offices, schools and hospitals are all priced the same way: how much there is, how we reach it, what state it’s in and when we can work. Ask for a fixed quote and we’ll go through it with you.
Asking for a quote
Photos and a few facts are often enough to price the work. Useful things to send:
- The site address and the type of premises
- The times we could work without disrupting the site
- A few general shots of the system
- The roof, plant room or outside wall the system runs to
If you need extract fan cleaning in City of London, call 0345 646 2711 or email us. Tell us what kind of premises it is and when it’s open, and send pictures or your last report if you can. A fixed quote typically follows within one working day.
What a clean will not put right
In fairness, some problems need a different fix:
- A faulty speed controller or isolator
- A fan that was never right for the kitchen
- A failed motor or worn bearings (that needs a fan repair or replacement)
If you are not sure, just give us a ring on 0345 646 2711 or send us an email and we’ll give you a straight answer before booking.
Parts of the system we cover

What the work involves, part by part
Inline duct fans
Hidden in a ceiling void, an inline fan is easily missed. The survey makes sure it’s part of the clean.
Wall fans
With little duct before them, wall fans collect grease fast. They may need cleaning as often as the canopy, which grease readings will show.
Do you need extract fan cleaning in City of London?
A fan in City of London builds up grease at a rate set by the kitchen, not the location: how many hours a day the kitchen runs and what it cooks. BESA guidance sets minimum intervals of 3, 6 or 12 months for the whole system by daily use.
Signs it’s time to call us include:
- Thick grease on the impeller and casing
- Burning smells from the fan area
- A fan that hums, whines or rumbles
- Weak extraction at the canopy
Healthcare kitchens, like those at hospitals such as London Bridge Hospital (about 0.6 miles south-east), often cook for long hours, which puts them in BESA’s heavier-use bands.
Questions to ask before booking
- Whether the figure could change on the day
- What happens if part of the system can’t be accessed
- When the next visit should be, and why
- When they can work, and whether that is outside your opening hours
Grease, kitchens and City of London
The FSA’s food hygiene register shows about 3,230 restaurants, cafés and works canteens and about 953 sandwich bars and takeaways across City of London and its immediate surroundings (about a mile and a half). Where they cook under a canopy, an extract fan is pulling grease-laden air through its blades every service. City of London sits within the area of London Fire Brigade. In most workplaces, including commercial kitchens, it’s the fire and rescue authority that enforces the Fire Safety Order. Night work suits London kitchens, and roads and loading bays tend to be quieter too.
If you run a church or community hall kitchen, near St Olave Old Jewry or elsewhere in City of London, its extract still collects grease from every lunch and event. If you look after a school kitchen, at a school such as Fashion Retail Academy or anywhere near City of London, the holidays are the usual time for a TR19® clean.

In-house cleaning or a specialist?
Day-to-day cleaning is something your team can do: wiping down canopy surfaces, cleaning filters and keeping a simple log. Inside the ducts, risers and fan is specialist work, and that’s where we come in.
If your staff spot something between visits, such as dripping grease, a noisy fan, a smell or a filter that will not come clean, it’s best reported rather than tackled in-house. We will take a look and give you a fixed quote.
