Extract fan cleaning for kitchens and businesses in Nunhead
If the extract fan in Nunhead has become noisy, weak or greasy? A few details or a photo help when you call 0345 646 2711 or email us, and we will give you a fixed quote for extract fan cleaning in Nunhead, normally within one working day. If you have rough running from the extract fan and a fan that no longer moves enough air, we can put it right, from fan housings, axial fans and centrifugal fans onwards.
Kitchens in Nunhead, like many across London, can share a building with flats or offices, with the duct running up through shared risers. A duct fire there can reach parts of the building far from the range, so a regular TR19® clean protects everyone in it.
It’s worth checking any contractor’s accreditations. We are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we hold CHAS, SafeContractor and ISO 9001, and we’re fully insured.

What a clean won’t put right
In fairness, some problems need a different fix:
- A fan that was never right for the kitchen
- A failed motor or worn bearings (that needs a fan repair or replacement)
- Wiring faults to the fan

The process
We turn up at the time agreed with you, often in the evening, overnight or at the weekend so the site keeps working. Equipment that has to be off is switched off and allowed to cool first, and the area around the work is covered and protected. On site, it takes an hour or two for one fan, longer when it’s hard to reach. Managed blocks in London often need contractors booked in ahead, and we’re happy to deal with the agent directly for a site in Nunhead.
- First we locate the fan and agree how it’s safely isolated.
- With the fan isolated, the housing is opened.
- Grease is scraped from the impeller blades and the inside of the housing.
- The fan and its surrounds are degreased, keeping clear of the motor’s electrics.
- We reassemble, run the fan and photograph the result.
Before we arrive
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
- Mention any sign-in, permit or induction we need
- Find the previous report, if there is one

Advice
In-house cleaning or a specialist?
A few tasks are always specialist work: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease call for the right kit, training and safe access. That’s our job.
When your team notices a problem between visits, such as dripping grease, a noisy fan, a smell or a filter that won’t come clean, they should report it rather than try to fix it. We can diagnose it and quote.
Different parts, different methods
Roof-mounted fans
Roof fans also discharge grease onto the roof around them, so the outlet area is checked too. We note any grease around the fan.
Impellers and blades
A clean impeller shows any damage: chips, distortion or wear. Anything we see goes on the report.
What happens if it’s left?
Vibration from an unbalanced impeller doesn’t stay small. It wears bearings and mounts and can lead to a breakdown, which may leave the kitchen without extraction. Cleaning it early is far less disruptive. London buildings are shared, so a fire or failure in one system can reach the neighbours above and beside you.
The price reflects the work, not guesswork. That’s why we survey first, from pictures or on site, and the price is agreed before we start.

Nunhead questions
What do you need to know about parking in Nunhead?
London parking can be tight, so details of loading bays and permits help. Working overnight, as we often do in London, usually makes it simpler.
Do you clean school canteen extracts around Nunhead out of term?
Yes, out-of-term visits are normal for schools. There are about 69 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of Nunhead. Tell us your holiday dates and we will book the visit for when the site is empty.
Why is my extract fan noisy?
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.
Do you have insurance?
Yes. Duct Doctor is fully insured, and we can share the details when you need them.
What’s TR19?
BESA’s ventilation hygiene specification, with two parts that matter most here: TR19® Grease for kitchen extract systems and TR19® Air for general ventilation. It is not law, but it’s the benchmark.
Is it safe to clean the fan while the kitchen is open?
We always isolate the fan first, so it cannot start while we work. With the extract off, the kitchen can’t cook, so we work out of hours.
Do you offer maintenance contracts?
Yes. Tell us what you have and how it’s used, and we will suggest a schedule and quote for it.
Can you look after several sites?
Yes. Tell us the addresses and what each needs and we will quote them together.
Do you need extract fan cleaning in Nunhead?
A greasy fan in Nunhead is fuel at the end of the duct. If grease in the duct catches, the fan and its housing can feed the fire, and a hot, struggling motor doesn’t help.
Most sites get in touch after spotting something like this:
- A fan that no longer moves enough air
- Vibration from an unbalanced impeller
- A fan motor running hot under a coat of grease
- A fan left out of previous cleans
Volunteers running a hall kitchen near Saint Antony with Saint Silas, or anywhere in Nunhead, may not know when the extract was last cleaned, and a grease test settles it.

Extract fan cleaning in Nunhead: the local picture

Any of them serving cooked food has an extract to keep clean, from canopy to discharge. Kitchens in Nunhead get their food hygiene inspections from Lewisham council. A greasy canopy or dripping filters are the sort of thing an inspection can pick up. A dated certificate in the maintenance file answers the question before it’s asked. The fire and rescue service for Nunhead is 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.

Aftercare tips
No system stays clean for ever, but care slows the build-up. A few tips:
- Keep the grease filters clean and in place
- Flag smoke lingering at the canopy
- Look for grease stains near the discharge
- Book the fan into every full TR19 clean
When we’ve finished, the fan is reassembled and run. If anything seems wrong, from vibration to wear, we note it, so you can plan any repair.
Make sure the fan is reachable. A fan that can be reached safely is a fan that gets cleaned, whether it’s on a roof, in a ceiling or on a wall.
