What happens if it’s left?
The fan is part of the fire path. TR19® Grease covers the whole extract, fan included and many insurers require the full system to be cleaned to TR19. Even a site near Oxhey that’s only busy part of the week needs its system checked on a schedule.
Working hours, access and the scale of the site all affect the cost. We take each of them into account, and the price is fixed before work begins.

How we handle extract fan cleaning in Oxhey
Every TR19® Grease clean includes the extract fan, but a fan can also need attention on its own, especially when it has started to vibrate or sound rough. A fan-only clean is recorded as exactly that. If you have a fan that no longer moves enough air and grease around the motor and its mounts, we can help.
Kitchens around a place like Oxhey are often in older buildings or single-storey extensions, where the duct may cross a roof void or climb an outside wall. Long horizontal runs like that hold grease and need access panels to reach.
Duct Doctor has been trading since 2009, and we are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we carry full insurance.

What else we do in Oxhey
Keeping the system healthy
Good habits slow the build-up between visits. Our tips:
- Flag smoke lingering at the canopy
- Keep access to the fan clear
- Never cook with a filter missing
- Make sure the fan is included each time
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.
Run the fan throughout cooking. Grease settles faster when the air stops moving, so keeping it running helps keep it clean.
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 grease that has passed the filters is out of reach. That part needs specialist access and equipment.
Some jobs should never be done in-house: entering ducts, working on fans, testing dampers and taking grease readings need training, the right equipment and safe access. Leave those to us.
Oxhey kitchens: local notes
Food Standards Agency records include about 25 pubs, bars and clubs in Oxhey and the streets around it, up to about 1.5 miles out. Wherever they cook, the canopy, duct and fan collect grease just as a restaurant’s do. In Oxhey, food businesses are inspected by environmental health officers from Hertsmere council. Extraction counts as kitchen equipment, so its condition can come up on the day. Our report lists what was cleaned and when, which is useful to have ready. Fire safety in Oxhey falls to Hertfordshire 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 Watford General Hospital, about 1.2 miles west, is the kind of site where a kitchen may cook for patients, staff and visitors all day. Volunteers running a hall kitchen near Church of St James, or anywhere in Oxhey, may not know when the extract was last cleaned, and a grease test settles it. For schools such as Bushey Manor Junior School, kitchen extract cleaning is normally booked for the holidays, when the canteen is closed.

What we do, step by step
Every visit runs to the same pattern: sheeting and protection first, make the system safe, carry out the extract fan cleaning, tidy up and leave you the report. On site, the work takes a few hours where there are several fans or heavy deposits. Because the survey comes first, a visit to Oxhey can usually be finished without a second trip.
- We find the fan and check how it’s reached and how it’s isolated.
- The fan is isolated so it can’t start while we work.
- We remove the grease from the blades, impeller and casing.
- Blades, housing and the area around the motor are degreased with care.
- We reassemble, run the fan and photograph the result.
Preparing for the visit
- Let us know about permits to work or site inductions
- Have your last certificate or report to hand
- Make sure equipment near the work can be switched off and left to cool
Get a fixed quote
The quickest way to a quote is to send pictures: the system from a couple of angles, plus any access panels or hatches. Add the site type and your opening hours, and we can price many jobs without a visit.
Advice
What the work involves, part by part
Kitchens with long cooking hours
A fan in a long-hours kitchen runs for most of the day, which means grease and wear add up quickly. Cleaning on time helps keep it running.
Impellers and blades
The blades of the impeller do the work, and it collects grease unevenly. An uneven coating throws it off balance, so it’s cleaned carefully blade by blade.
What affects the quote in Oxhey
The quote reflects the site in front of us. We take into account:
- The size of the system
- The condition of the system
- Travel, parking and unloading
- The number of sites or systems
No two sites are the same, so each one gets its own fixed quote. The size of the job, how we reach it, its condition and the working hours all make a difference.
What to send for a quote
You don’t need the technical terms. Just send:
- Any previous report or certificate
- A few general shots of the system
- The site address and the type of premises
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
To help us quote: the address, the type of site and when it’s open, pictures of the system and the last certificate or report, if there is one. Then call 0345 646 2711, or email photos.
Oxhey: your questions answered
Do you clean school canteen extracts around Oxhey out of term?
Yes, and it’s the easiest time to do it. With about 32 schools and colleges on the FSA’s register within roughly a mile and a half of Oxhey, it pays to plan holiday dates ahead. You can call us on 0345 646 2711 or use the quote form with the dates the site is empty.
Can you get to a site in Oxhey?
Yes. Oxhey 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.
Do you look at the system first?
Yes, every time. Diagnosis comes before treatment: the survey tells us what the system needs and how to reach it, and the quote is based on that.
Who is responsible for fire safety on the premises?
It depends on the building. Under the Fire Safety Order 2005, it’s the responsible person, which may be the employer, owner, landlord, facilities manager or managing agent.
What accreditations do you have?
CHAS, SafeContractor, ISO 9001 and BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease. We’re fully insured and have been trading since 2009.
Can you come out in an emergency?
Yes, 24/7. Office hours are Monday to Friday, 8am to 6pm, with the emergency line covering every other hour.
What’s the cleaning interval for an extract fan?
It depends on how many hours the kitchen cooks, under BESA guidance. Heavy use means at least every 3 months, light use at least every 12, fan included.
How much does extract fan cleaning cost?
The cost depends on the size of the system, its condition, access and timing. Call for a fixed quote, usually ready within one working day.
Landlords, agents and facilities managers
If you look after several sites, we can plan visits across the whole estate and price them together. Each site gets its own report and photos, so records stay tidy.
Running several sites is easier with one contractor. We work across London and the South East, so visits at different addresses can be planned together and kept to a regular schedule.
