Extract fan cleaning in Childs Hill, done properly
If the extract fan in Childs Hill has become noisy, weak or greasy? Tell us about it when you ring 0345 646 2711 or use the quote form, and you will get a fixed price, normally within one working day. Typical jobs include vibration from an unbalanced impeller and a motor area thick with grease, on fan housings, roof-mounted fans and in-line fans.
In a London area like Childs Hill, a kitchen extract often passes through shared space on its way out: a riser, a service void, the floors above. Grease in a duct like that is a fire risk to the whole building, not just the kitchen, which is why keeping it clean to TR19® matters.
Nothing is signed off by word of mouth: a dated report with pictures of the work, and for TR19® Grease cleans, a certificate issued through the BESCA VHE portal. Any parts we couldn’t reach are recorded on it too.

Aftercare tips
Good habits slow the build-up between visits. A few tips:
- Listen for new noises or vibration from the fan
- Don’t turn the fan off mid-service
- Check the report shows the fan was cleaned
- File the fan’s report with your other records
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.
Keep the whole system on its cleaning cycle. A fan cleaned with the rest of the system on time rarely gets badly coated, in line with BESA guidance.

Childs Hill: your questions answered
Who carries out food hygiene inspections in Childs Hill?
The local authority for Childs Hill is Barnet council, and its environmental health team does the inspecting. How often a business is inspected depends on the risk rating the council gives it, so it’s worth staying ready all year.
Is parking a problem for work in Childs Hill?
London parking can be tight, so details of loading bays and permits help. Night visits tend to make loading easier on London streets.
Which kinds of sites do you work on?
Commercial premises of every kind: kitchens, offices, schools, healthcare, retail, leisure and food production. We fit the work around how the site operates.
Can you look after several sites?
Yes. We work across South East England and London, so sites at different addresses can be planned together as one programme. Each site gets its own report and photos.
Is the fan included in a TR19 clean?
Yes. TR19® Grease covers the whole system, fan included. It’s isolated, opened and cleaned along with the canopy, plenum, filters, ducts and discharge.
Is the fan isolated during cleaning?
It has to be off and isolated before anyone touches it. We clean out of hours, in the evening, overnight or at weekends, so cooking isn’t affected.
Are you fully insured?
Yes. Duct Doctor is fully insured, and we can share the details when you need them.
What makes a kitchen extract fan vibrate?
Often it’s grease on the impeller. Grease collects unevenly and unbalances the impeller, causing vibration and noise. Cleaning may sort it, but worn bearings or a failing motor need a repair.
Signs you need extract fan cleaning in Childs Hill
Grease builds up unevenly on the blades. Over time, that imbalance shakes the fan and puts strain on the bearings. What starts as a grease problem can become a mechanical one.
The symptoms we are asked about most are:
- Burning smells from the fan area
- Grease escaping from the fan outlet
- An extract fan with no cleaning record
- An extract fan that vibrates or rattles
If you run a church or community hall kitchen, near All Saints or elsewhere in Childs Hill, its extract still collects grease from every lunch and event.

The process
Every visit runs to the same pattern: protect the area, isolate whatever needs isolating, carry out the extract fan cleaning, clear away and leave you the report. On site, the work takes an hour or two for one fan, longer when it’s hard to reach. Loading bays, visitor permits and roof access are the first things we ask about for a site in Childs Hill.
- 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.
- 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.
Getting ready for the visit
- Tell us about site rules, permits or sign-in
- Make sure someone can let us in and lock up afterwards
- Let us know when the site is closed or quiet
Ask for a quote
Every quote begins with a look at the system, from your photos and details or, where that isn’t enough, a survey on site. After that, you get a fixed price for the work so you know the cost before we start.

Grease, kitchens and Childs Hill
The FSA’s food hygiene register includes about 35 pubs, bars and clubs and about 17 hotels, B&Bs and guest houses within roughly a mile and a half of the centre of Childs Hill. Where they serve hot food, their kitchen extracts need cleaning to TR19® like any restaurant’s. Most London extract cleaning happens at night, after the last service. Kitchens in Childs Hill get their food hygiene inspections from Barnet council. A greasy canopy or dripping filters are the sort of thing an inspection can pick up. Our report lists what was cleaned and when, which is useful to have ready.
Term dates shape school work: for a school like All Saints' CofE Primary School NW2, an extract clean fits neatly into a half-term or summer break. Healthcare kitchens, like those at hospitals such as New End Hospital (about 0.9 miles east), often cook for long hours, which puts them in BESA’s heavier-use bands.

What the work involves, part by part
Kitchens with long cooking hours
When a busy kitchen’s fan fails, cooking stops. A clean fan is less likely to strain, and our 24/7 emergency callout is there if it happens anyway.
Roof-mounted fans
A roof fan sits in cooler air, so grease can settle heavily. We scrape and degrease the blades and casing.
