- Thick grease on the impeller and casing
- A motor area thick with grease
- An extract fan that vibrates or rattles
What happens on the day
Before we leave, we walk the area with whoever is on site. We point out anything that couldn’t be reached or needs a follow-up, and it goes on the report too. The visit takes an hour or two for most single fans. If the van will struggle with a lane or gateway near Wonersh, let us know and we’ll plan around it.
- Diagnosis first: we look for grease, noise and vibration.
- With the fan isolated, the housing is opened.
- Each blade is cleaned so the impeller runs evenly.
- We clean the casing, the outlet and around the motor.
- We run the fan and note its condition in the photo report.
Getting ready for the visit
- Arrange a key holder or contact on site
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
- Find the previous report, if there is one
Getting a quote
Getting a quote doesn’t take long. Call or email with a few details and you will typically have a fixed price within one working day. Where a survey is needed, we arrange a time that suits the site.

Extract fan cleaning for kitchens and businesses in Wonersh
In Wonersh, as everywhere we work, the fan follows a set routine: isolated first, then opened, scraped and degreased. Your report shows the impeller as we found it and as we left it. The work covers fan housings, roof-mounted fans and axial fans, and common reasons people get in touch are a fan left out of previous cleans and grease around the motor and its mounts.
In a small place like Wonersh, kitchens are often in older or extended buildings, with long single-storey duct runs, where grease settles in the flat sections. Access, parking and timings are agreed before the day.
For insurers and inspectors, the record counts. So every job comes with a written report and photos, plus a TR19® certificate through the BESCA VHE portal where the work is a TR19® Grease clean.

Wonersh: your questions answered
Do you clean school canteen extracts around Wonersh out of term?
Yes. The holidays are the usual time for school work. The FSA’s register shows about 7 schools and colleges with food registrations within roughly a mile and a half of Wonersh. Send us your term dates when you phone us on 0345 646 2711, or send details by email, and we’ll fit the work in.
Who enforces fire safety at workplaces in Wonersh?
Fire safety enforcement in Wonersh is handled by Surrey Fire and Rescue Service. Records of extract cleaning are a sensible thing to have ready if a fire safety officer carries out an audit.
Do you offer extract fan cleaning separately?
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.
Can one contract cover all our sites?
Yes. You deal with one contact for every site across London and the South East, with visits on a regular schedule.
Does the law say we must follow TR19?
No. The law sets the duty, and TR19® is the recognised benchmark for meeting it. Under the Fire Safety Order 2005, the responsible person must reduce fire risk, and without records, many insurers may refuse or reduce a claim.
How much does extract fan cleaning cost?
We do not publish prices, because the cost depends on the job: the size of the system, its condition, access and when we can work. We fix the price before work begins.
Do we need to close while you work?
Not normally. Booking the work out of hours means the site can carry on as normal. Larger jobs can be phased over several visits to keep things running.
Should the extract fan be cleaned as part of TR19?
Yes, the fan is part of a full TR19® Grease clean. We clean it alongside the canopy, ductwork and discharge.
Looking after it afterwards
Results last longer with the right care. Here’s what we suggest:
- Watch for grease marks around the outlet
- Make sure the fan is included each time
- Don’t turn the fan off mid-service
- Leave a clear route to the fan
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. Regular full cleans keep the fan from building up heavy deposits, in line with BESA guidance.

When to call us in Wonersh
By the time air reaches the fan, it has passed the canopy, filters and duct. The grease that’s left lands on the blades and the casing, and the spinning blades fling it onto the walls of the housing.
Common reasons sites call us are:
- Weak extraction at the canopy
- Hot, greasy smells near the fan
- A fan that hums, whines or rumbles
- A fan motor running hot under a coat of grease
A hall kitchen that only cooks for events, whether near Wonersh United Reformed Church or elsewhere in Wonersh, still needs its extract cleaned, just less often.
Comparing quotes
- Whether the work can be done while the site is closed
- Whether the whole system is included, or only the parts that are easy to reach
- Which accreditations they hold, and whether you can check them
- What happens if part of the system cannot be accessed
Landlords, agents and facilities managers
For anyone managing more than one site, we can plan visits across the whole estate and price them together. Every building has its own written report, so records stay tidy.
Managing agents often deal with us directly. Send the address, what’s needed and how access works and we will come back with a fixed quote.
In-house cleaning or a specialist?
Your own staff can handle the daily basics: wiping canopies, washing grease filters and recording it in a log. What they cannot safely do is clean inside the ductwork, the fan or the risers, and that is where we come in.
If your staff spot something between visits, like drips, unusual noise, smells or damaged filters, it’s best reported rather than tackled in-house. We can diagnose it and quote.
Wonersh kitchens: local notes
Food Standards Agency data counts about 6 cafés, restaurants and staff canteens within 1.5 miles or so of the middle of Wonersh. The fan at the end of each of those extracts collects grease that slows it and wears the motor. Surrey Fire and Rescue Service covers Wonersh. Grease in a kitchen extract is a recognised fire risk, and the fire authority enforces the law on managing it in most commercial premises. Kitchens in Wonersh get their food hygiene inspections from Waverley council. The cleanliness of the kitchen and its equipment, extraction included, is part of what they check. Keeping each certificate and photo report on file helps show the extract is looked after.
Chilworth Manor, about 1.7 miles north, is one of the historic houses near Wonersh; if you run event catering at a venue like that, cleans can be booked between functions. Bursars and site managers at schools such as Bramley CofE Aided Infant School and Nursery tend to book extract cleaning for when the kitchen is empty.

When something else is needed
An honest diagnosis matters more to us than a booking, so here’s what extract fan cleaning won’t do:
- A failed motor or worn bearings (that needs a fan repair or replacement)
- Electrical faults in the fan’s supply or controls (an electrician’s job)
- Grease in the canopy and ductwork

Where we work
- In-line fans
- Axial fans
- Roof-mounted fans

Different parts, different methods
Roof-mounted fans

Inline duct fans
Some fans are built into the duct itself. They’re reached through access panels or by opening the casing, once they’re isolated.
