How we handle extract fan cleaning in How Green
Duct Doctor has been cleaning kitchen extract fans since 2009. As a BESCA Vent Hygiene Elite member, we clean to BESA TR19® Grease, with CHAS, SafeContractor and ISO 9001 and full insurance. If you have vibration from an unbalanced impeller and a fan left out of previous cleans, we can help.
Rural kitchens often have long, low duct runs through a roof space or along an outside wall, and those horizontal sections are where grease settles. We agree access and timings in advance.
It’s worth checking any contractor’s accreditations. We are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we hold CHAS, SafeContractor and ISO 9001, and we are fully insured.

Looking after it afterwards
Aftercare is simple, and it helps at the next visit:
- Flag smoke lingering at the canopy
- Do not turn the fan off mid-service
- File the fan’s report with your other records
- Look for grease stains near the discharge
The photo report shows the fan before and after cleaning. It lists what was cleaned and anything we couldn’t reach, along with the recommended next clean date.
Listen to the fan. New noise or vibration often means grease is building on the impeller and early action can save a repair.
Why act early in How Green
Grease on the fan is grease in the system. A TR19 clean that left out the fan wouldn’t cover the whole system, and insurers asking for TR19 cleaning expect the full system. A fault that closes a site in a village like How Green affects everyone who depends on it.
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.

Take a look at what affects the cost and our accreditations and certificates.
What affects the cost of extract fan cleaning
The quote reflects the site in front of us. We take into account:
- Travel, parking and unloading
- One-off work versus a regular cycle
- When the work can happen, such as evenings, overnight or weekends
- Site requirements such as sign-in and permits
The price reflects the work, not guesswork. That is why every job is surveyed first, and the price is agreed before work begins.
What to send for a quote
Photos and a few facts are often enough to price the work. Useful things to send:
- Any symptoms, from odd noises to smells or leaks
- Close-ups of filters, grilles, hatches or access panels
- The postcode and the type of business
- Wide photos of the system and the area around it
To help us quote: where the site is, what it is and its opening hours, a few photos and any previous report or certificate. Once you have those, ring 0345 646 2711, or email photos.
Do you need extract fan cleaning in How Green?
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.
What we’re most often called out for:
- Grease around the motor and its mounts
- A noisy fan that has got louder over time
- A fan that no longer moves enough air
- Thick grease on the impeller and casing
Term dates shape school work: for a school like Hever Church of England Voluntary Aided Primary School, an extract clean fits neatly into a half-term or summer break.

- We start by checking where the fan sits and how to isolate it.
- Power to the fan is isolated before anyone touches it.
- The impeller and the housing around it are scraped clean.
- Blades, housing and the area around the motor are degreased with care.
- We reassemble, run the fan and photograph the result.
How to prepare
- Let us know about permits to work or site inductions
- Make sure someone can let us in and lock up afterwards

FAQs for How Green
Can the work in How Green be done at night or at weekends?
Yes, out-of-hours work is a big part of what we do. Your customers, staff or residents in How Green needn’t be disturbed. Your opening times are the first thing we ask for.
Do you cover smaller places like How Green?
Yes, smaller places are covered as well as towns. The journey is planned ahead, so a few details about the route help.
Can you set up regular visits?
Yes. Plans on a 3, 6 or 12-monthly cycle are available, depending on what the system needs.
What information do you need?
Just the basics: the address, the site type, your opening hours and how we reach the system. Photos and the last report help too. After that, simply phone us on 0345 646 2711, or email photos.
How long is a fan clean?
Allow an hour or two for one fan, longer when it’s hard to reach. We will confirm the time when we quote.
What happens to the waste?
It leaves the site with us at the end of the visit. While we work, it’s kept contained so the area stays clean.
Can the fan be cleaned between full cleans?
Yes, a fan can be cleaned on its own. It’s useful when a fan is noisy or greasy between full cleans, but it doesn’t replace a full TR19 clean.
What does extract fan cleaning cost?
Every site is different, so each gets its own fixed quote. To get one, phone us on 0345 646 2711 or drop us a line with the site type, opening hours and a few photos.
What staff can safely do
For ventilation and air handling systems, in-house care is mostly about checks: keeping grilles clear, noting unusual noise or smells and logging filter changes. The inside of ducts and units needs a specialist.
Good housekeeping makes our visits easier, not unnecessary. Clean filters and tidy surfaces slow the build-up, but hidden parts of the system still need specialist attention.
Multi-site and managed buildings
We regularly work with managing agents. Tell us the site, the work and the access arrangements and we will come back with a fixed quote.
Landlords, managing agents and facilities managers book us, not only the businesses that use the systems. Shared systems, like a riser serving several units, need a clear agreement on who books the work, and we can quote for the whole system.
