About our extract fan cleaning in Four Ashes
If the ducts are the arteries, the fan is the heart. A greasy fan works harder and moves less air. Our job is to clear it, check it runs smoothly and record what we found so you get a clean bill of health. Typical jobs include rough running from the extract fan and thick grease on the impeller and casing, on centrifugal fans, discharge points and in-line fans.
Somewhere as small as Four Ashes, commercial kitchens are few: perhaps a pub, a school or care home kitchen, or a hall used for events. Each still has a canopy and duct that collect grease.
Our accreditations include CHAS, SafeContractor and ISO 9001, and we are fully insured. On top of that, we are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we’ve been trading since 2009.

Staff cleaning versus specialist work
Keep a record of what your team does. A dated log of in-house cleaning and checks helps show that the system is managed between specialist visits, next to our reports.
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.

What else we do in Four Ashes
When to call us in Four Ashes
How fast a fan gets greasy in Four Ashes depends on the cooking: daily hours and the amount of frying and grilling. Under BESA guidance, the whole system, fan included, needs cleaning at least every 3, 6 or 12 months depending on daily hours.
If you notice any of these, it’s worth a diagnosis:
- A heavily greased fan housing
- A motor area thick with grease
- A fan that no longer moves enough air
- Rough running from the extract fan
If you run a church or community hall kitchen, near St Michael and All Angels Church or elsewhere in Four Ashes, its extract still collects grease from every lunch and event.
Questions to ask before you book
- What insurance they carry
- Whether VAT is included
- Whether the quote is based on a survey or pictures
- Whether they recommend a next date
Between visits
After the visit, a few habits help the work last:
- Report grease escaping from the fan
- Do not store items in front of the fan’s access point
- Make sure the fan is included each time
- Check filters are seated before cooking
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.
A change in how the fan sounds is worth noting. Rattles, hums or shaking can be early signs of build-up or wear, and catching it early keeps it a cleaning job.
The process
The first job on site is protection: floors, worktops and anything near the work are covered. After that, the system is made safe and the work begins. The work on site takes a couple of hours per fan, depending on its size and the build-up, and the area is cleaned down before we leave. Photos of the system and how to reach it help us plan a visit to Four Ashes.
- We locate the fan and plan how to reach and isolate it.
- 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.
Preparing for the visit
- Mention any sign-in, permit or induction we need
- Dig out any earlier paperwork for the system
- Clear loose items from the work area

Advice
When it’s something else
Some problems need a different service or another trade:
- A fan that is too small for the system (a design question)
- A cracked or broken impeller (it needs replacing)
- A faulty speed controller or isolator
If in doubt, ring 0345 646 2711 or email us and we will say what we think.
Where we work
- Fan housings
- Axial fans
- In-line fans
- Roof-mounted fans
- Discharge points
- Centrifugal fans
Different parts, different methods
Roof-mounted fans
A roof fan sits in cooler air, so grease can settle heavily. We scrape and degrease the blades and casing.
Fan housings and motors
Belt-driven fans have a drive belt and pulleys that can collect grease. Belts and pulleys are checked and cleaned where safe for your records.

Questions from Four Ashes
Which fire authority looks after Four Ashes?
That’s Buckinghamshire Fire and Rescue Service. TR19® is not law, but it’s the benchmark many fire officers and insurers look to when they ask how often the extract is cleaned.
Which environmental health team covers Four Ashes?
That’s Buckinghamshire council, whose environmental health officers carry out food hygiene inspections in Four Ashes. How often a business is inspected depends on the risk rating the council gives it, so it’s worth staying ready all year.
Is it safe to clean the fan while the kitchen is open?
The fan is isolated before we open it, so it cannot start while we work. That means the extract is off, so we clean while the kitchen is closed.
Is there a survey before the work?
Yes. For many sites, pictures and a few details are enough, and larger or hidden systems get a visit.
Do you work in Four Ashes?
Yes. Our technicians work in Four Ashes, within the South East and London area we cover.
Will I get pictures of the cleaned fan?
Photos, notes on condition and a recommended next date. Keep it with your maintenance log.
Why has my extract fan got louder?
An unbalanced impeller, normally from uneven grease, is a common cause. After cleaning, we’ll tell you if wear or damage is also involved.
Who is the responsible person?
Under the Regulatory Reform (Fire Safety) Order 2005, it’s the responsible person: often the employer, owner or occupier. In shared or managed buildings, a landlord, facilities manager or managing agent can share the duty.
