Bishop's Sutton extract fan cleaning
Cleaning of kitchen extract fans, impellers, fan housings and discharge points for businesses, landlords and public buildings in Bishop's Sutton. BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease.
- A fan that no longer moves enough air
- A heavily greased fan housing
- A motor area thick with grease
How we handle extract fan cleaning in Bishop's Sutton
A fan never collects grease in a neat, even layer. Heavier deposits on some blades throw the impeller off balance, which brings vibration, noise and extra wear on the bearings and motor. Cleaning the impeller and housing puts that right. If you’re dealing with less air being pulled from the kitchen and a fan coated in grease inside its housing, we can help, from discharge points, roof-mounted fans and centrifugal fans onwards.
Work in a small place like Bishop's Sutton starts with a call to agree access and timings, and the clean covers the whole system, as it would anywhere: canopy, filters, duct, fan and discharge, with a certificate and photo report at the end.
Good records are part of the job. You get a written report with pictures after each visit, listing what was done, anything we couldn’t reach and when the next visit is due. File it in your maintenance log so it’s ready for an insurer, fire officer or EHO.

Bishop's Sutton kitchens: local notes
The FSA’s data shows about 5 bars, pubs and nightclubs registered in and around Bishop's Sutton, up to about a mile and a half out. Where they serve hot food, their kitchen extracts need cleaning to TR19® like any restaurant’s. Kitchens in Bishop's Sutton get their food hygiene inspections from Winchester City council. An officer looking round a kitchen will see the canopy, and grease there is hard to miss. A dated certificate in the maintenance file answers the question before it’s asked. Hampshire and Isle of Wight Fire and Rescue Service covers Bishop's Sutton. In most workplaces, including commercial kitchens, it’s the fire and rescue authority that enforces the Fire Safety Order.

Between visits
To keep the system working properly between visits:
- File the fan’s report with your other records
- Don’t store items in front of the fan’s access point
- Never cook with a filter missing
- Listen for new noises or vibration from the fan
We take away the grease and dirty water from the fan clean. Wherever the fan is, the area around it is cleaned down.
Listen to the fan. New noise or vibration often means grease is building on the impeller and early action can save a repair.
What we’re called out for in Bishop's Sutton
A fan in Bishop's Sutton builds up grease at a rate set by the kitchen, not the location: how many hours a day the kitchen runs and what it cooks. Under BESA guidance, the whole system, fan included, needs cleaning at least every 3, 6 or 12 months depending on daily hours.
Most sites get in touch after spotting something like this:
- Thick grease on the impeller and casing
- A smell of hot grease from the extract
- Less air being pulled from the kitchen
- A fan that hums, whines or rumbles
School kitchens, at schools like Perins School for example, are typically cleaned in the holidays so no lunches are lost.
Questions to ask before booking
- Proof of insurance
- What happens if part of the system can’t be accessed
- How they set the interval to the next visit
- Whether the figure could change on the day
Multi-site and managed buildings
If you look after several sites, we can schedule visits across all of them on one quote. Every building has its own written report, so records stay tidy.
Landlords, managing agents and facilities managers book us, not only the businesses that use the systems. Where a system serves more than one tenant, such as a shared riser, it helps to agree who arranges the work, and we can quote for the whole system.
How it works
The first job on site is protection: floors, worktops and anything near the work are covered. Then we make the system safe and start. The work on site takes an hour or two for one fan, longer when it’s hard to reach, and the area is cleaned down before we leave. For a village or hamlet like Bishop's Sutton, tell us about narrow lanes, gates and parking when you book.
- We start by checking where the fan sits and how to isolate it.
- The fan is isolated so it can’t start while we work.
- Grease is scraped from the impeller blades and the inside of the housing.
- We degrease the fan and housing, taking care around the motor.
- It’s closed up, run and checked, and photos go into your report.
Before we arrive
- Make sure someone can let us in and lock up afterwards
- Tell us the best time to work, such as after service or at a weekend
- Tell us about site rules, permits or sign-in

Related advice
What the work involves, part by part
Impellers and blades
The blades of the impeller do the work, and grease builds up on them unevenly. An uneven coating throws it off balance, so it’s cleaned carefully blade by blade.
Roof-mounted fans
Roof fans also discharge grease onto the roof around them and we check the area around the outlet. We note any grease around the fan.
Honest limits
We’d rather tell you now than book work that won’t help, so these are the things it won’t cover:
- Electrical faults in the fan’s supply or controls (an electrician’s job)
- An undersized fan that cannot cope
- Damaged fan blades
Not sure which it is? You can call 0345 646 2711 or drop us a line and we’ll tell you honestly.
What the work covers
- Fan housings
- Roof-mounted fans
- In-line fans
- Discharge points
- Axial fans
- Centrifugal fans
Bishop's Sutton: your questions answered
Will you come out to Bishop's Sutton?
Yes. Villages and rural sites across the South East are part of our work, Bishop's Sutton included. Just mention lanes, gates or anything else about the site when you book.
Who carries out food hygiene inspections in Bishop's Sutton?
The local authority for Bishop's Sutton is Winchester City council, and its environmental health team does the inspecting. Have your latest TR19® certificate and photo report to hand, as an officer may ask how the extract is maintained.
Do you look at the system first?
Yes, every time. Diagnosis comes before treatment: the survey tells us what the system needs and how to reach it and the fixed quote is built on it.
Is TR19 a legal requirement?
No. TR19® itself is not law; it’s a BESA specification. The legal duty comes from the Regulatory Reform (Fire Safety) Order 2005: the responsible person must assess and reduce fire risk, and TR19® is the benchmark for showing that grease in the extract is under control.
Why has my extract fan got louder?
Uneven grease on the impeller often causes it. After cleaning, we’ll tell you if wear or damage is also involved.
What does TR19 mean?
A BESA specification in two main parts: TR19® Grease for kitchen extract systems and TR19® Air for general ventilation. It is not law, but it’s the benchmark.
Can one contract cover all our sites?
Yes. We work across South East England and London, so sites at different addresses can be planned together on one programme. Every site has its own report.
Will I get photos of the cleaned fan?
Before and after pictures go into a report, along with notes on the fan’s condition. For a full TR19 clean, you also get a certificate through the BESCA Vent Hygiene Elite portal.
Why deal with it now?
Grease on a roof fan can also escape outside. That stains surfaces and can add to the fire risk outside the building, which is one more reason to keep it clean. With notice, the visit to Bishop's Sutton can be fitted around your bookings and events.
What you pay reflects the actual work. That is why every job is surveyed first, and the price is agreed before we start.
