Extract Fan Cleaning in Cudworth
Need extract fan cleaning in Cudworth? We diagnose first, fix the price and book the work around your hours, then sign off with a report and photos.
- An extract fan with no cleaning record
- A fan shaking on its mounts
- A fan that hums, whines or rumbles
What your team can do, and what needs us
If your staff spot something between visits, such as dripping grease, a noisy fan, a smell or a filter that will not come clean, it’s best reported rather than tackled in-house. We’ll take a look and give you a fixed quote.
Staff cleaning does not replace a specialist visit; it supports it. Regular in-house cleaning slows the build-up, but the parts you cannot see still need a specialist at the right interval.
Extract fan cleaning in Cudworth, done properly
Grease on a fan is not spread evenly. Heavier deposits on some blades throw the impeller off balance, which brings vibration, noise and extra wear on the bearings and motor. A thorough clean removes the cause. Common call-outs are for vibration from an unbalanced impeller and burning smells from the fan area, across centrifugal fans, roof-mounted fans and in-line fans.
Rural kitchens often have long, low duct runs through a roof space or along an outside wall, where grease settles in the flat sections. We agree access and timings in advance.
Nothing is signed off by word of mouth: a written report, dated and illustrated with photos, and for TR19® Grease cleans, a certificate issued through the BESCA VHE portal. Any parts we couldn’t reach are recorded on it too.

The process
When we arrive, we check the system against the survey or the photos you sent. Anything unexpected is raised with you before we go further. From there, it takes an hour or two for most single fans. The timing of a visit to Cudworth is set by you, and the travel is our side of the planning.
- Diagnosis first: we look for grease, noise and vibration.
- With the fan isolated, the housing is opened.
- The impeller is cleaned blade by blade so it runs balanced.
- Housing, outlet and the area around the motor are cleaned.
- We run the fan and note its condition in the photo report.
How to prepare
- Mention any parking or loading restrictions
- Plan for cooking equipment or plant to be off before we arrive
- Move anything stored near the system
Getting a quote
Photos are enough for some jobs, while others need a look on site. Larger sites, and anything hidden behind walls, ceilings or floors, are normally surveyed first. Either way, the quote is fixed before any work is booked.
Advice
Do you need extract fan cleaning in Cudworth?
Grease condenses as the air cools, and a fan out on a roof or wall often sits where the air is coolest. So grease often settles heavily there.
Most sites get in touch when they notice something like this:
- Less air being pulled from the kitchen
- Thick grease on the impeller and casing
- A fan that hums, whines or rumbles
- Grease escaping from the fan outlet
If you run a church or community hall kitchen, near Church of St Peter or elsewhere in Cudworth, its extract still collects grease from every lunch and event.
Before booking anyone

- Whether inaccessible sections are listed on the report
- Whether the price is fixed
What extract fan cleaning cannot fix
To be straight with you, some problems need a different fix:
- An impeller that is bent or split
- A fan that was never right for the kitchen
- A fan that will not start
Not sure which it is? You can ring 0345 646 2711, or email photos and we will tell you honestly.

Keeping the system healthy
So the system stays in good health:
- Listen for new noises or vibration from the fan
- Leave a clear route to the fan
- Tell us if the extract feels weaker
- Keep the fan on whenever the range is lit
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 route to the fan clear. Clear access means it’s never left out of a clean, whether it’s on a roof, in a ceiling or on a wall.
Grease, kitchens and Cudworth
According to Food Standards Agency records, there are about 3 hotels, B&Bs and guest houses within roughly a mile and a half of the centre of Cudworth. Wherever they cook, the canopy, duct and fan collect grease just as a restaurant’s do. In Cudworth, food businesses are inspected by environmental health officers from Mole Valley council. A greasy canopy or dripping filters are the sort of thing an inspection can pick up. A TR19® certificate and photo report after each clean gives you a record to show an inspector. Cudworth is covered by Surrey 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.
If you run catering at a healthcare site, such as a hospital like Langley Green Hospital about 3.8 miles south-east, the extract may need cleaning more often than a part-time kitchen. If you look after a school kitchen, at a school such as Newdigate CofE Endowed Aided Infant School or anywhere near Cudworth, the holidays are the usual time for a TR19® clean.

Cudworth questions
Can the work in Cudworth be done at night or at weekends?
Yes, out-of-hours work is a big part of what we do. It means the site in Cudworth keeps running as normal. Your opening times are the first thing we ask for.
Do you clean school canteen extracts around Cudworth out of term?
Yes, holiday work suits schools best. Around Cudworth, the Food Standards Agency lists about 2 schools and colleges with registered kitchens within a mile and a half or so. Send us your term dates when you call 0345 646 2711, or email photos, and we’ll fit the work in.
What does TR19 mean?
TR19® is the BESA specification for keeping ventilation systems clean. Since 2019, TR19® Grease has been a standalone specification for grease in kitchen extract systems, and TR19® Air covers general supply and extract systems.
Do you need to turn the fan off to clean it?
We always isolate the fan first, so it cannot run during the clean. With the extract off, the kitchen cannot cook, so we work out of hours.
Can you look after several sites?
Yes. Send the list of sites and the work at each and you will get one fixed quote.
What accreditations do you have?
Our accreditations are CHAS, SafeContractor and ISO 9001, alongside BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease. Vent Hygiene Elite is run by BESCA and independently audited.
What does extract fan cleaning cost?
We don’t publish prices, because the cost 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 any work starts.
Do you offer emergency callouts?
Yes, day and night, every day of the year. Office hours are Monday to Friday, 8am to 6pm, with the emergency line covering every other hour.
What happens if it’s left?
Grease on the fan is grease in the system. A TR19 clean that left out the fan wouldn’t cover the whole system, and insurers asking for TR19 cleaning expect the full system. Equipment tucked in a roof space or outbuilding near Cudworth rarely gets looked at unless someone books it.
What you pay reflects the actual work. That’s why we survey first, from photos or on site, and why the quote is fixed before any work starts.

How the job changes from site to site
Wall fans
Wall fans often have a short duct, so grease reaches them quickly. They may need cleaning as often as the canopy, which grease readings will show.
Kitchens with long cooking hours
In a busy kitchen, the fan rarely gets a rest, which means grease and wear add up quickly. Regular cleans help it keep going.
