Extract fan cleaning in Derringstone, Kent
One call covers extract fan cleaning in Derringstone: survey, fixed quote, work and sign-off. Fully insured, with CHAS, SafeContractor and ISO 9001.
- A fan that has never been cleaned
- Fat spreading onto the roof or wall by the fan
- Less air being pulled from the kitchen
Keeping the system healthy
Results last longer with the right care. Here’s what we suggest:
- Leave a clear route to the fan
- Run the extract throughout cooking
- Listen for new noises or vibration from the fan
- Keep records of every fan clean
When the fan is cleaned as part of a full TR19® Grease clean, a TR19 certificate is issued through the BESCA Vent Hygiene Elite portal. A fan-only clean is recorded in the photo report.
Run the fan throughout cooking. Grease settles faster when the air stops moving, so keeping it running helps keep it clean.
Extract fan cleaning for kitchens and businesses in Derringstone
Duct Doctor has been cleaning kitchen extract fans since 2009. We are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we are fully insured, with CHAS, SafeContractor and ISO 9001. We’re often asked to deal with a noisy fan that has got louder over time and grease escaping from the fan outlet, on roof-mounted fans, discharge points and in-line fans.
In a village or hamlet like Derringstone, the kitchens that need extract cleaning are typically a pub, a school, a care home or a hall kitchen, wherever there is one. Every one of them still needs its extract kept clear of grease.
For insurers and inspectors, the record counts. That is why every job is written up in a report with photos, and grease extract cleans come with a TR19® certificate issued through the BESCA Vent Hygiene Elite portal.

Questions from Derringstone
Which environmental health team covers Derringstone?
Food hygiene inspections in Derringstone are carried out by Canterbury City council. An officer may look up into the canopy, so clean filters on the day and a recent certificate on file both help.
Do you work overnight in Derringstone?
Yes, we can come after you close and finish before you open. Your customers, staff or residents in Derringstone needn’t be disturbed. When you give us a ring on 0345 646 2711 or send us an email, mention when the site is quiet.
Is there a survey before the work?
Yes. For many sites, photos and a few details are enough, while bigger or harder-to-see systems are surveyed on site.
What does extract fan cleaning cost?
There’s no set price, as it depends on the job: how big it is, what state it’s in, how we reach it and the working hours. You get a fixed price before work begins.
What do you do with what you remove?
We contain it and take it with us. Grease, debris and waste water are collected as the work goes on rather than letting it spread.
How much notice should we give?
That depends on the slot you want and the size of the job. Mention your preferred dates with your enquiry, and if it’s an emergency, call us any time.
Why is my extract fan noisy?
Often it’s grease on the impeller. Uneven build-up on the blades throws the fan off balance, causing vibration and noise. Cleaning may sort it, but worn bearings or a failing motor need a repair.
Is the fan isolated during cleaning?
It has to be off and isolated, for safety. Cleans are done when the kitchen is closed, so cooking is not affected.
What staff can safely do
Good housekeeping makes our visits easier, not unnecessary. Clean filters and tidy surfaces slow the build-up, but the parts you cannot see still need a specialist at the right interval.
For ventilation and air handling systems, in-house care is mostly about checks: clear grilles, a log of filter changes and reporting anything odd. Cleaning inside ducts and units is specialist work.
Why act early in Derringstone
A greasy fan has to work harder to move the same air. Less air is pulled from the kitchen, so heat and smoke linger, while the motor runs under more strain. It’s simpler to plan the work at Derringstone now than to arrange it in a hurry later.
What you pay reflects the actual work. That is why every job is surveyed first, and the price is agreed before we start.

Common problems we fix in Derringstone
The cooler the air, the more grease drops out, and on a roof or outside wall the fan can be in some of the coolest air in the system. That makes it a natural place for grease to settle.
If you notice any of these, it’s worth a diagnosis:
- A fan motor running hot under a coat of grease
- A smell of hot grease from the extract
- A fan that has never been cleaned
- Less air being pulled from the kitchen
If you run a church or community hall kitchen, near Church of St John the Baptist or elsewhere in Derringstone, its extract still collects grease from every lunch and event.

- The fan is found and its type, access and isolation checked.
- We isolate the power before opening the housing.
- We scrape the heavy grease from the blades and housing.
- The fan is degreased, taking care around the motor.
- It’s closed up, run, checked and photographed for the report.
How to prepare

Extract fan cleaning in Derringstone: the local picture
Food Standards Agency data counts about 3 restaurants, cafés and canteens within roughly a mile and a half of the centre of Derringstone. The fan at the end of each of those extracts collects grease that slows it and wears the motor. Derringstone sits within the area of Kent Fire and Rescue Service. 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 Derringstone, food businesses are inspected by environmental health officers from Canterbury City council. An officer looking round a kitchen will see the canopy, and grease there is hard to miss. A TR19® certificate and photo report after each clean gives you a record to show an inspector.
