Extract fan cleaning in Warnham
Duct Doctor has been cleaning kitchen extract fans since 2009. We’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we’re fully insured, with CHAS, SafeContractor and ISO 9001. If you’re dealing with fat spreading onto the roof or wall by the fan and a fan coated in grease inside its housing, we can help.
Somewhere as small as Warnham, commercial kitchens are few: perhaps a pub, a school or care home kitchen, or a hall used for events. Each still has a canopy and duct that collect grease.
Nothing is signed off by word of mouth: a dated report with photos of the work, plus a certificate through the BESCA Vent Hygiene Elite portal when the work is a TR19® Grease clean. It shows what was done and what, if anything, couldn’t be reached.

Multi-site and managed buildings
Records are where multi-site compliance often slips. Every visit ends with a dated report and pictures, ready to show insurers, fire officers or EHOs.
If you look after several sites, we can schedule visits across all of them on one quote. Every building has its own written report, so records stay tidy.
Extract fan cleaning around Warnham
The FSA’s data shows about 3 pubs and bars registered within 1.5 miles or so of the middle of Warnham. A pub or hotel kitchen that cooks every day builds up grease in its extract like any other. In Warnham, food businesses are inspected by environmental health officers from Horsham council. An officer looking round a kitchen will see the canopy, and grease there is hard to miss. A dated certificate in the maintenance file answers the question before it’s asked. Fire safety in Warnham falls to West Sussex Fire and Rescue Service. In most workplaces, including commercial kitchens, it’s the fire and rescue authority that enforces the Fire Safety Order.
For schools such as Warnham CofE Primary School, kitchen extract cleaning is normally booked for the holidays, when the canteen is closed. If you run a church or community hall kitchen, near The Parish Church of St Margaret or elsewhere in Warnham, its extract still collects grease from every lunch and event.

Different parts, different methods
Fan housings and motors
Belt-driven fans have a drive belt and pulleys that can collect grease. We clean around them and note any wear for your records.
Wall fans
Wall fans often have a short duct, so grease reaches them quickly. They may need cleaning as often as the canopy, which grease readings will show.

What else we do in Warnham
Signs you need extract fan cleaning in Warnham
A fan in Warnham builds up grease at a rate set by the kitchen, not the location: daily hours and the amount of frying and grilling. Under BESA guidance, the whole system, fan included, needs cleaning at least every 3, 6 or 12 months depending on daily hours.
The symptoms we’re asked about most include:
- A fan left out of previous cleans
- A motor area thick with grease
- A noisy fan that has got louder over time
- Hot, greasy smells near the fan
Healthcare kitchens, like those at hospitals such as Horsham Hospital (about 1.8 miles south-east), often cook for long hours, which puts them in BESA’s heavier-use bands.

Looking after it afterwards
Simple habits between visits make a real difference. Our advice:
- Make sure the fan is included each time
- Keep records of every fan clean
- Notice when the fan starts to sound different
- Keep the grease filters clean and in place
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.
Stick to the interval for the full extract. A fan cleaned with the rest of the system on time rarely gets badly coated, in line with BESA guidance.
What staff can safely do
In-house cleaning and specialist cleaning do different jobs. Wiping filters daily and washing them weekly keeps the visible parts in order, but they do not reach the grease that builds up further in. That part needs specialist access and equipment.
Staff cleaning does not replace a specialist visit; it supports it. Regular in-house cleaning slows the build-up, but the parts you cannot see still need a specialist at the right interval.
Questions from Warnham
Can you work in Warnham outside opening hours?
Yes, out-of-hours work is a big part of what we do. That way a site in Warnham does not have to lose a day’s trading. Your opening times are the first thing we ask for.
Is Warnham within the area you cover?
Yes. Warnham is within the area we cover across London and the South East. Just mention lanes, gates or anything else about the site when you book.
What is TR19?
It’s the industry benchmark for cleaning ventilation and kitchen extract systems, written by BESA. It sets out inspection, cleaning and record keeping, and it takes a risk-based approach.
How far ahead should we book?
Earlier is better, especially for out-of-hours work. Quotes normally come back within one working day, and there’s a 24/7 line for emergencies.
What happens if you cannot reach some of it?
We record them on the report, with photos where possible, and we explain what access is needed, such as extra access panels in ductwork.
Can you come out in an emergency?
Yes, day and night, every day of the year. Office hours are Monday to Friday, 8am to 6pm, with the emergency line covering every other hour.
What happens to the waste?
Anything we remove is contained as we work and taken away with us, including grease, debris and dirty water. We don’t leave it behind.
Do you work with multi-site operators?
Yes. We work across South East England and London, so we can schedule a run of sites as one programme. Each site gets its own report and photos.
Why deal with it now?
Without a working extract fan, a kitchen cannot cook safely. Many fan problems start with grease, so keeping it clean is part of keeping it running. We also offer a 24/7 emergency callout if the worst happens. Our emergency line runs 24/7, but a planned visit to Warnham is calmer for everyone.
A single site or a whole portfolio, we price it on the same basis: what needs doing, how we get to it and when. The price is fixed before we start.
Why us?
- A BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease
- A fixed price before any work starts
- A written report with pictures after each visit

How it works
Your staff don’t need to do much on the day. Someone lets us in at the agreed time and shows us where everything is, and the rest is down to us. Afterwards, the area is left tidy and the written report follows. The timing of a visit to Warnham is set by you, and the travel is our side of the planning.
- First we locate the fan and agree how it’s safely isolated.
- Power to the fan is isolated before anyone touches it.
- Grease is scraped from the impeller blades and the inside of the housing.
- We degrease the fan and housing, taking care around the motor.
- We reassemble, run the fan and photograph the result.
How to prepare
- Tell us the best time to work, such as after service or at a weekend
- Allow time for equipment near the work to be turned off and cool down
- Clear loose items from the work area
How to get a quote
The quickest way to a quote is to send photos: wide shots of the system, close-ups of anything that worries you and how we’d get to it. Tell us what kind of site it is and when it’s open, and we can price many jobs without a visit.
