Extract fan cleaning in East Barnet, done properly
If the ducts are the arteries, the fan is the heart. A heart under strain works harder for less. Our job is to clear it, check it runs smoothly and record what we found, before signing it off. If you have a motor area thick with grease and a noisy fan that has got louder over time, we can put it right, from centrifugal fans, discharge points and fan housings onwards.
London kitchens tend to trade late and open early, so work in East Barnet is normally booked for the night or the early hours. Parking, loading and access to the roof are agreed with the building before the night of the clean.
Duct Doctor has been trading since 2009, and we’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we’re fully insured.

The process
Every visit runs to the same pattern: protect the area, isolate whatever needs isolating, carry out the extract fan cleaning, tidy up and hand over the paperwork. On site, the work takes an hour or two for most single fans. Managed blocks in London often need contractors booked in ahead, and we are happy to deal with the agent directly for a site in East Barnet.
- First we locate the fan and agree how it’s safely isolated.
- The fan is isolated so it cannot start while we work.
- The impeller and the housing around it are scraped clean.
- The fan and its surrounds are degreased, keeping clear of the motor’s electrics.
- It’s closed up, run and checked, and photos go into your report.
Before we arrive
- Tell us the best time to work, such as after service or at a weekend
- Tell us where we can park and unload
- Tell us about site rules, permits or sign-in
Getting a quote
To get a fixed quote, phone us on 0345 646 2711, or send details by email with the site type, your trading hours and a short description of the system. Photos and the last report, if you have one, make the quote quicker. We usually come back within one working day.

Extract fan cleaning in East Barnet: the local picture
Food Standards Agency data counts about 169 cafés, restaurants and staff canteens and about 71 takeaways within roughly a mile and a half of the centre of East Barnet. Each kitchen extract among them ends at a fan, and grease on the impeller strains the motor. East Barnet sits within the area of London Fire Brigade. Fire and rescue authorities enforce the Fire Safety Order in most non-domestic premises, and in a kitchen that fire risk includes the grease in the extract. Kitchens in East Barnet get their food hygiene inspections from Barnet council. They look at how clean the premises and equipment are, and the kitchen extract is part of that. A TR19® certificate and photo report after each clean gives you a record to show an inspector.
If you run a café or takeaway near Oakleigh Park station, early starts and late finishes leave little time to clean, so overnight extract cleaning suits. Volunteers running a hall kitchen near St Mary the Virgin, or anywhere in East Barnet, may not know when the extract was last cleaned, and a grease test settles it.

Aftercare tips
After the visit, a few habits help the work last:
- Tell us if the extract feels weaker
- Don’t turn the fan off mid-service
- Look for grease stains near the discharge
- Keep each photo report with the maintenance log
When we have finished, the fan is reassembled and run. If anything seems wrong, from vibration to wear, we note it, so you can plan any repair.
Stick to the interval for the full extract. Regular full cleans keep the fan from building up heavy deposits, in line with BESA guidance.
What staff can safely do
Away from the kitchen, the in-house job is mainly checking: keeping grilles clear, noting unusual noise or smells and logging filter changes. Cleaning inside ducts and units is specialist work.
Logging matters as much as cleaning. A simple log of filter washes, wipe-downs and checks helps show that the system is managed between specialist visits, alongside our reports.
Managing agents and facilities teams in East Barnet
We also work for facilities teams across offices, schools and healthcare in East Barnet and across Greater London. Larger estates can be phased building by building to keep disruption down.
Managing agents often deal with us directly. Send the address, what’s needed and how access works and we’ll come back with a fixed quote.
Why deal with it now?
Vibration from an unbalanced impeller does not stay small. It can wear the bearings and lead to failure, which may leave the kitchen without extraction. Cleaning it early is far less disruptive. It’s better booked as a planned job in East Barnet than handled as an emergency.
Combining work into one visit or one programme often makes better use of the time. Tell us about everything you’d like looked at and we will price it together.

Common problems we fix in East Barnet
A fan in East Barnet builds up grease at a rate set by the kitchen, not the location: how many hours a day the kitchen runs and what it cooks. Under BESA guidance, the whole system, fan included, needs cleaning at least every 3, 6 or 12 months depending on daily hours.
Look out for any of the following:
- A motor area thick with grease
- A noisy fan that has got louder over time
- A fan that no longer moves enough air
- A fan shaking on its mounts
Healthcare kitchens, like those at hospitals such as Finchley Memorial Hospital (about 2.2 miles south-west), often cook for long hours, which puts them in BESA’s heavier-use bands.

We’d rather tell you now than book work that won’t help, so these are the things it won’t cover:

- A dirty duct upstream of the fan
- A faulty speed controller or isolator

East Barnet: your questions answered
What do you need to know about parking in East Barnet?
We plan it in advance, so let us know about loading bays, permits and access rules at the building. Night visits tend to make loading easier on London streets.
Do you clean school canteen extracts around East Barnet out of term?
Yes, holiday work suits schools best. There are about 51 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of East Barnet. Just give us a ring on 0345 646 2711, or email photos with your term dates and we’ll plan around them.
How often does the fan need cleaning?
Daily cooking hours set the minimum in BESA guidance. Heavy use means at least every 3 months, light use at least every 12, fan included.
Which accreditations do you hold?
We hold CHAS, SafeContractor and ISO 9001, and we’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. The Vent Hygiene Elite scheme is run by BESCA and audited independently.
What happens if you cannot reach some of it?
The report shows them clearly. Often the fix is extra access, such as new panels in ductwork, and we can fit those.
What information do you need?
Just the basics: the address, the site type, your opening hours and how we reach the system. Photos and any previous paperwork make it quicker. Then ring 0345 646 2711 or use the quote form.
Who is the responsible person?
It depends on the building. The Fire Safety Order 2005 puts the duty on the responsible person, which can be the employer, the owner, a landlord, an FM or a managing agent.
Can we book visits on a schedule?
Yes. Regular plans can run on 3, 6 or 12-monthly cycles, to suit the system and how it’s used.
