Extract fan cleaning for kitchens and businesses in South Darenth
In South Darenth, as everywhere we work, the fan follows a set routine: we isolate it, open the housing, scrape the impeller and degrease the lot. Your report shows the impeller as we found it and as we left it. We are often asked to deal with grease around the motor and its mounts and rough running from the extract fan, on in-line fans, axial fans and fan housings.
For a kitchen in or near South Darenth, the visit is planned around opening hours and the journey, and the clean itself is the same full TR19® job as in any town: canopy to discharge, then a TR19® certificate and a photo report.
Accreditations are easy to claim and worth checking. Ours are BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease, plus CHAS, SafeContractor and ISO 9001, with full insurance on top.

Questions from South Darenth
Who inspects food businesses in South Darenth?
The local authority for South Darenth is Sevenoaks council, and its environmental health team does the inspecting. An officer may look up into the canopy, so clean filters on the day and a recent certificate on file both help.
Can you come to South Darenth after we close?
Yes, evening, overnight and weekend work is normal for us. The site is handed back ready to open. Your opening times are the first thing we ask for.
Are you insured?
Yes. We are fully insured, and we can share the details when you need them.
What accreditations do you have?
Duct Doctor is 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 does TR19 mean?
BESA’s ventilation hygiene specification in two main parts: TR19® Grease for kitchen extracts and TR19® Air for supply and extract systems. It isn’t law, but it’s the benchmark.
Is there a survey before the work?
Yes, always. We diagnose before we treat: the survey shows what needs doing and what access we need, and the quote is based on that.
Can you clean the fan on its own?
Yes, we can clean just the fan. It’s useful when a fan is noisy or greasy between full cleans, but it does not replace a full TR19 clean.
Should the extract fan be cleaned as part of TR19?
Yes, a full TR19 clean includes the fan. Anything that cannot be reached is recorded, so you always know what was cleaned.

Part by part
Kitchens with long cooking hours
A fan in a long-hours kitchen runs for most of the day, so grease and wear build up together. Cleaning on time helps keep it running.
Wall fans
A wall fan pushes the air straight outside. It’s isolated, opened and cleaned inside and out.
In-house cleaning or a specialist?
Day-to-day cleaning is something your team can do: wiping down canopy surfaces, cleaning filters and keeping a simple log. Inside the ducts, risers and fan is specialist work, which is where we come in.
Good housekeeping makes our visits easier, not unnecessary. Clean filters and tidy surfaces slow the build-up, but hidden parts of the system still need specialist attention.
When something else is needed
In fairness, some problems need a different fix:
- A dirty duct upstream of the fan
- Wiring faults to the fan
- A fan that won’t start
Not sure which it is? You can call 0345 646 2711 or use the quote form and we will tell you honestly.

Multi-site and managed buildings
From a single site to a large estate, you get the same standard: the system surveyed, the price fixed, the visit fitted around trading and everything written up afterwards.
Managing agents often deal with us directly. Send the address, what’s needed and how access works, and we’ll send a fixed quote.
Looking after it afterwards
Results last longer with the right care. Here’s what we suggest:
- Never cook with a filter missing
- Keep each photo report with the maintenance log
- Keep access to the fan clear
- 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.
Don’t run the kitchen with the extract off. Air that keeps moving carries vapour out rather than letting it settle, so keeping it running helps keep it clean.
When to call us in South Darenth
A fan collects more grease when the filters let more through. When filters do not seal, grease goes straight through to the fan, so the fan takes far more than it should.
Signs it’s time to call us include:
- A fan left out of previous cleans
- An extract fan that vibrates or rattles
- Grease around the motor and its mounts
- Thick grease on the impeller and casing
For schools such as Horton Kirby Church of England Primary School, kitchen extract cleaning is usually booked for the holidays, when the canteen is closed.

What extract fan cleaning looks like in South Darenth
There are about 4 cafés, restaurants and staff canteens and about 5 takeaways in South Darenth and the streets around it, up to about 1.5 miles out, according to the Food Standards Agency’s register. The fan at the end of each of those extracts collects grease that slows it and wears the motor. Kent Fire and Rescue Service covers South Darenth. Grease in a kitchen extract is a recognised fire risk, and the fire authority enforces the law on managing it in most commercial premises. In South Darenth, food businesses are inspected by environmental health officers from Sevenoaks council. Extraction counts as kitchen equipment, so its condition can come up on the day. Keeping each certificate and photo report on file helps show the extract is looked after.
Church and community hall kitchens, near The Parish Church of Saint Mary or anywhere around South Darenth, are easy to forget, but their extracts collect grease like any other. Healthcare kitchens, like those at hospitals such as Darenth Park Hospital (about 2.3 miles north), often cook for long hours, which puts them in BESA’s heavier-use bands.

What happens on the day
The first job on site is protection: sheeting goes over floors and surfaces close to the work. After that, the system is made safe and the work begins. It takes a few hours where there are several fans or heavy deposits, and the area is cleaned down before we leave. Somewhere as small as South Darenth, the date and timings are agreed with you well before the day.
- The fan is found and its type, access and isolation checked.
- We isolate the power before opening the housing.
- Grease is scraped off the impeller blades and casing.
- Blades, housing and surrounds are degreased with care around the electrics.
- It’s closed up, run, checked and photographed for the report.
Before we arrive
- Have your last certificate or report to hand
- Agree a time when the area can be out of use
- Plan for cooking equipment or plant to be off before we arrive
