Extract fan cleaning for kitchens and businesses in High Wych
Kitchen extract fans come in different forms: fans on the roof, fans built into the duct run, and fans on an outside wall. Each is isolated and opened in its own way, and we plan that during the survey. We’re often asked to deal with a motor area thick with grease and vibration from an unbalanced impeller, across discharge points, axial fans and fan housings.
In a small place like High Wych, kitchens are often in older or extended buildings, with long single-storey duct runs, and those horizontal sections are where grease settles. We agree access and timings in advance.
The sign-off is always in writing: a dated report with pictures of the work, plus a certificate through the BESCA Vent Hygiene Elite portal when the work is a TR19® Grease clean. Any parts we couldn’t reach are recorded on it too.

Questions from High Wych
Which environmental health team covers High Wych?
That is East Hertfordshire council, whose environmental health officers carry out food hygiene inspections in High Wych. Have your latest TR19® certificate and photo report to hand, as an officer may ask how the extract is maintained.
Which fire and rescue service is responsible for High Wych?
It’s Hertfordshire Fire and Rescue Service, which covers High Wych. A recent cleaning certificate and a note of the next clean date show that grease in the extract is being managed.
What’s TR19?
A BESA specification, with two parts that matter most here: TR19® Grease for kitchen extract systems and TR19® Air for general ventilation. It is not legislation, but it’s the standard people check against.
Can the work be done while we are closed?
Yes. Evenings, nights and weekends are normal working hours for us, so you don’t have to close during trading.
Why has my extract fan got louder?
Build-up on the impeller is a frequent reason, because it unbalances the fan. Worn bearings and motor problems are others, which our report will flag.
Where does the waste go?
We take it away when we go. During the work, it’s contained to keep the area clean.
How do you keep the site clean during the work?
We start with protection: floor sheeting and covers over nearby surfaces and equipment. The area is left tidy, with our waste taken away.
Do we lose a day’s trading?
Not normally. The area we’re working in has to be out of use while we are there, so we book a time when it would be closed anyway.

What else we do in High Wych
Common problems we fix in High Wych
Poor filters mean a greasier fan. When filters don’t seal, grease goes straight through to the fan, so the fan takes far more than it should.
If you notice any of these, it’s worth a diagnosis:
- An extract fan that vibrates or rattles
- A fan that has never been cleaned
- A smell of hot grease from the extract
- Thick grease on the impeller and casing
Healthcare kitchens, like those at hospitals such as Princess Alexandra Hospital (about 3 miles south-west), often cook for long hours, which puts them in BESA’s heavier-use bands.
Before you book anyone
- What’s included in the scope, part by part
- How areas they cannot reach will be recorded
- Whether they recommend a next date
- Which accreditations they hold, and whether you can check them
Aftercare tips
Looking after the system between visits is straightforward, and it makes the next visit easier:
- Leave a clear route to the fan
- Run the extract throughout cooking
- Flag smoke lingering at the canopy
- Listen for new noises or vibration from the fan
You get before and after photos of the impeller and housing. It notes what was done and anything that couldn’t be reached, 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.
The process
Everything the job needs comes with us, including protection sheets, the right tools and access kit. All we need from you is clear access and the right equipment switched off. On site, the work takes an hour or two for most single fans. If you can send pictures, we can arrive in High Wych knowing what to expect.
- First we locate the fan and agree how it’s safely isolated.
- With the fan isolated, the housing is opened.
- The impeller and the housing around it are scraped clean.
- The fan and its surrounds are degreased, keeping clear of the motor’s electrics.
- The fan is put back into service, checked and photographed.
How to prepare
- Allow time for equipment near the work to be turned off and cool down
- Let us know about permits to work or site inductions
- Find the previous report, if there is one
Getting a quote

Why deal with it now?
A greasy fan has to work harder to move the same air. Airflow at the canopy drops and the kitchen gets hotter and smokier and the motor works harder. If the system at a site near High Wych fails, there may be nowhere nearby to move to.

Part by part
Kitchens with long cooking hours
A fan in a long-hours kitchen runs for most of the day, which means grease and wear add up quickly. Cleaning on time helps keep it running.
Inline duct fans
Space around an inline fan can be tight, so the method is planned in advance. Anything out of reach is recorded.
What extract fan cleaning cannot fix
Before booking, it helps to know what’s not included:
- A cracked or broken impeller (it needs replacing)
- Grease in the canopy and ductwork
- A fan that will not start
If you’re not sure, just give us a ring on 0345 646 2711, or email photos and we will give you a straight answer.

In-house cleaning or a specialist?
Logging matters as much as cleaning. A simple log of filter washes, wipe-downs and checks shows an inspector that the system is looked after between visits, alongside our reports.
Some jobs should never be done in-house: entering ducts, working on fans, testing dampers and taking grease readings need training, the right equipment and safe access. Leave those to us.
