Extract fan cleaning in The City, done properly
We’ve been trading since 2009. As a BESCA Vent Hygiene Elite member, we clean to BESA TR19® Grease, with CHAS, SafeContractor and ISO 9001 and full insurance. Typical jobs include hot, greasy smells near the fan and a fan coated in grease inside its housing, on roof-mounted fans, in-line fans and centrifugal fans.
Somewhere as small as The City, commercial kitchens are few: perhaps a pub, a school or care home kitchen, or a hall used for events. Every one of them still needs its extract kept clear of grease, whatever the size of the place.
Think of the report as the system’s health record: dated, with photos, and showing what was done. For TR19® Grease cleans, the certificate comes through the BESCA Vent Hygiene Elite portal, ready for your insurer.

When to call us in The City
A fan collects more grease when the filters let more through. Missing, damaged or badly fitted filters let grease travel the whole system, so the fan takes far more than it should.
It’s time to book a visit if you see:
- A fan that no longer moves enough air
- A fan shaking on its mounts
- A motor area thick with grease
- A fan left out of previous cleans
If your kitchen is in a listed or historic building, like the houses around The City (West Wycombe Park House is about 2.7 miles south-east), fitting access panels needs care.
What your quote should include
- Proof of accreditation you can verify
- Whether the whole system is included, or only the parts that are easy to reach
- How areas they can’t reach will be recorded
- What insurance they carry
Multi-site and managed buildings
For anyone managing more than one site, we can plan visits across the whole estate and price them together. Every building has its own written report, so records stay tidy.
Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person must assess and reduce fire risk, which may be the employer, owner, landlord, FM or managing agent. Where responsibility is shared, records matter even more.
Aftercare tips
How long the results last depends on use and care. Here’s what we suggest:
- Keep access to the fan clear
- Tell us if the extract feels weaker
- Report grease escaping from the fan
- Notice when the fan starts to sound different
Where the fan needs repair rather than cleaning, the report says so. We also repair and replace extract fans, so you have one point of contact.
Listen to the fan. Rattles, hums or shaking can be early signs of build-up or wear and early action can save a repair.

What else we do in The City
What affects the cost of extract fan cleaning
The price is fixed before any work begins. It’s based on:
- Site rules, permits and inductions
- When the work can happen, such as evenings, overnight or weekends
- The size of the system
- Parking and loading at the site
No two sites are the same, so we price each one individually. Size, access, the condition of the system and when we can work all make a difference.
What we need to know
To help us quote quickly, please include:
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- Your last certificate, test record or report
- Photos showing the whole system and its surroundings
- The postcode and the type of business
Photos are enough for some jobs, while others need a look on site. Larger sites, and anything hidden behind walls, ceilings or floors, are normally surveyed first. Either way, the quote is fixed before any work is booked.
The City kitchens: local notes
There are about 4 cafés, restaurants and staff canteens within about 1.5 miles of central The City, according to the Food Standards Agency’s register. The fan at the end of each of those extracts collects grease that slows it and wears the motor. Kitchens in The City get their food hygiene inspections from Buckinghamshire council. An officer looking round a kitchen will see the canopy, and grease there is hard to miss. Keeping each certificate and photo report on file helps show the extract is looked after. Fire safety in The City falls to Buckinghamshire Fire and Rescue Service. Grease in a kitchen extract is a recognised fire risk, and the fire authority enforces the law on managing it in most commercial premises.
Where a hall near Church of St Paul, or anywhere in The City, hosts lunch clubs or events, its extract gathers grease just as a café’s does. School kitchens, at schools like Radnage Church of England Primary School for example, are normally cleaned in the holidays so no lunches are lost.

Your questions about extract fan cleaning in The City
Do you work in villages like The City?
Yes. Villages and rural sites across the South East are part of our work, The City included. Let us know about access, parking and anything unusual about getting there when you book.
Who carries out food hygiene inspections in The City?
In The City, it’s Buckinghamshire council that carries out food hygiene inspections. It helps to keep the extract cleaning records with your food safety paperwork, so they’re ready if asked for.
How long does extract fan cleaning take?
That depends on the fan’s size, its position and how much grease there is. Typically it takes a few hours where there are several fans or heavy deposits.
Can the work be done while we’re closed?
Yes. Much of our work happens in the evening, overnight or at weekends, so the site doesn’t lose a service.
Can you clean the fan on its own?
Yes, we can clean just the fan. It’s useful when a fan is noisy or greasy between full cleans, but it doesn’t replace a full TR19 clean.
Do you provide a report after cleaning the fan?
Photos, notes on condition and a recommended next date. Keep it with your maintenance log.
Are you fully insured?
Yes. Duct Doctor is fully insured, and the details are available on request.
Is TR19 a legal requirement?
Not in itself. Insurers, fire officers and EHOs look to TR19® as the benchmark, and many insurers ask for proof of cleaning to it. The law behind it is the Fire Safety Order 2005 in England and Wales.
How the visit works
Everything the job needs comes with us, including protection sheets, the right tools and access kit. All we need from you is clear access and the right equipment switched off. On site, the work takes an hour or two for most single fans. Visits to a village like The City are booked in advance, at a time that suits whoever runs the site.
- Diagnosis first: we look for grease, noise and vibration.
- Once isolated, we open the fan up.
- Each blade is cleaned so the impeller runs evenly.
- We clean the casing, the outlet and around the motor.
- We run the fan and note its condition in the photo report.
How to prepare
- Make sure equipment near the work can be switched off and left to cool
- Let us know when the site is closed or quiet
- Dig out any earlier paperwork for the system

Leave it or put it right?
A fan that sounds rough in The City is often telling you the extract needs a clean. Grease on the fan means grease in the duct before it so a full TR19 clean may be due. In a place like The City, ductwork and fans are easy to forget until something goes wrong.
We don’t list prices on the website, because each job is priced on what it involves. For a fixed quote, ring 0345 646 2711 or drop us a line, and we will talk you through it.
