Extract fan cleaning in Offham, done properly
Duct Doctor has been cleaning kitchen extract fans since 2009. As a BESCA Vent Hygiene Elite member, we clean to BESA TR19® Grease, and we are fully insured, with CHAS, SafeContractor and ISO 9001. The work covers fan housings, centrifugal fans and discharge points, and common reasons people get in touch are a noisy fan that has got louder over time and grease escaping from the fan outlet.
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.
The report is your system’s health record: a dated account with photos of everything we did. Grease extract cleans are also certificated to TR19® Grease through the BESCA VHE portal, ready for your insurer.

What we do, step by step
We’re used to working while the site is closed. Evenings, nights and weekends are when much of our work happens, so the site can open as normal afterwards. The visit itself takes a couple of hours per fan, depending on its size and the build-up. Photos of the system and how to reach it help us plan a visit to Offham.
- 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.
- We reassemble, run and photograph the fan.
Getting ready for the visit
- Plan for cooking equipment or plant to be off before we arrive
- Clear loose items from the work area
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
Getting a quote
We do not publish a price list, because every site is different. Instead, we look at your site first, from pictures or a survey, then send a fixed quote. To start, phone us on 0345 646 2711 or send us an email.

Part by part
Roof-mounted fans
Many kitchen extracts end at a fan on the roof. We clean them where they can be safely reached, with any limits noted.
Kitchens with long cooking hours
Kitchens that cook 12 to 16 hours a day put the most grease through their fans. BESA guidance sets at least 3-monthly cleaning for that level of use, fan included.
When to call us in Offham
The cooler the air, the more grease drops out, and on a roof or outside wall the fan can be in some of the coolest air in the system. So grease often settles heavily there.
Signs it’s time to call us include:
- Weak extraction at the canopy
- Hot, greasy smells near the fan
- Grease escaping from the fan outlet
- A noisy fan that has got louder over time
Bursars and site managers at schools such as Wallands Community Primary School tend to book extract cleaning for when the kitchen is empty.

Between visits
Simple habits between visits make a real difference. Our advice:
- Run the extract throughout cooking
- Check filters are seated before cooking
- Don’t store items in front of the fan’s access point
- Watch for grease marks around the outlet
You get before and after photos of the impeller and housing. It notes what was done and anything that couldn’t be reached, along with the recommended next clean date.
Keep the route to the fan clear. Clear access means it’s never left out of a clean, whether it’s on a roof, in a ceiling or on a wall.
Why it’s worth doing now in Offham
The fan is part of the fire path. A TR19 clean that left out the fan wouldn’t cover the whole system, and insurers asking for TR19 cleaning expect the full system. Somewhere as small as Offham, losing a kitchen or building to a fault is felt by everyone who uses it.
When the work has to happen, how we reach it and how big the site is all affect the cost. Each of those is built into the quote, and the price is fixed before any work starts.

For landlords and multi-site operators
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 each one has its own record.
Facilities teams in offices, schools and healthcare sites book us too across East Sussex. Work can be phased by floor, building or site to keep disruption down.
Offham kitchens: local notes
Food Standards Agency records list about 5 restaurants, cafés and canteens in Offham and the streets around it, up to about 1.5 miles out. Each kitchen extract among them ends at a fan, and grease on the impeller strains the motor. Kitchens in Offham get their food hygiene inspections from Lewes council. The cleanliness of the kitchen and its equipment, extraction included, is part of what they check. A TR19® certificate and photo report after each clean gives you a record to show an inspector. Offham is covered by East Sussex Fire and Rescue Service. In most workplaces, including commercial kitchens, it’s the fire and rescue authority that enforces the Fire Safety Order.
A hospital like Lewes Victoria Hospital, about 1.2 miles south, is the kind of site where a kitchen may cook for patients, staff and visitors all day. A hall kitchen that only cooks for events, whether near Church of St Peter or elsewhere in Offham, still needs its extract cleaned, just less often.

Offham questions
Which environmental health team covers Offham?
Food hygiene inspections in Offham are carried out by Lewes council. An officer may look up into the canopy, so clean filters on the day and a recent certificate on file both help.
Will you come out to Offham?
Yes. Offham is within the area we cover across London and the South East. The journey is planned ahead, so a few details about the route help.
How often does the fan need cleaning?
The fan follows the full system’s interval, from every 3 months for 12 to 16 hours of cooking a day to every 12 months for 2 to 6 hours. Readings may show it needs cleaning more often.
What do you do with what you remove?
Waste is contained during the work and removed when we leave, from grease and debris to used cleaning water. We don’t leave it behind.
Is the fan isolated during cleaning?
We isolate the fan, so the kitchen cannot cook while we work. That’s why fan cleans are done out of hours, and the kitchen is ready when we leave.
Do you survey before quoting?
Yes. Every job is surveyed first, either from photos and details you send or on a site visit. A fixed quote follows.
What do you do to protect the area?
By covering it before any work starts. The work is kept contained and clean down when we finish.
What does extract fan cleaning cost?
The cost depends on the size of the system, its condition, access and timing. Call for a fixed quote, normally ready within one working day.
How we price extract fan cleaning
The survey tells us what the work involves. We look at:
- Where the site is and how we reach it
- One-off work versus a regular cycle
- How easy every part is to reach
- Any permits to work or inductions
What you pay depends on how big the system is, what state it’s in and access to every part of it. You get a fixed price before any work starts, so there are no surprises.
Asking for a quote
There’s no need for technical detail. Just send:
- The site address and the type of premises
- Your opening hours and when the area is out of use
- Wide photos of the system and the area around it
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
Here’s what helps us quote: the address, the type of site and when it’s open, a few pictures and any previous report or certificate. Once you have those, phone us on 0345 646 2711, or send details by email.
