How we handle extract fan cleaning in Kemprow
We have been trading since 2009. We are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, with CHAS, SafeContractor and ISO 9001 and full insurance. The work covers fan housings, roof-mounted fans and axial fans, and common reasons people get in touch are fat spreading onto the roof or wall by the fan and a fan that hums, whines or rumbles.
Somewhere as small as Kemprow, commercial kitchens are few: perhaps a pub, a school or care home kitchen, or a hall used for events. Every one of them still needs its extract kept clear of grease.
Think of the report as the system’s health record: a dated account with pictures of everything we did. For TR19® Grease cleans, the certificate comes through the BESCA Vent Hygiene Elite portal and sits alongside the report.

Aftercare tips
To keep the system working properly between visits:
- Keep the fan on whenever the range is lit
- Keep records of every fan clean
- Make sure the fan is included each time
- Never cook with a filter missing
When the fan is cleaned as part of a full TR19® Grease clean, a TR19 certificate is issued through the BESCA Vent Hygiene Elite portal. A fan-only clean is recorded in the photo report.
Do not run the kitchen with the extract off. Air that keeps moving carries vapour out rather than letting it settle, so keeping it running helps keep it clean.
Common problems we fix in Kemprow
The cooler the air, the more grease drops out, and on a roof or outside wall the fan can be in some of the coolest air in the system. So grease often settles heavily there.
Any of these means the system needs a check-up:
- A fan shaking on its mounts
- An extract fan with no cleaning record
- Less air being pulled from the kitchen
- Rough running from the extract fan
Kitchens that cook twelve hours or more a day, as some healthcare kitchens do, fall into BESA’s three-monthly minimum; Shenley Hospital is the nearest hospital to Kemprow, about 2.3 miles north-east.

In-house cleaning or a specialist?
When your team notices a problem between visits, such as dripping grease, a noisy fan, a smell or a filter that won’t come clean, they should report it rather than try to fix it. We’ll take a look and send you a fixed quote.
A few tasks are always specialist work: entering ducts, working on fans, testing dampers and taking grease readings call for the right kit, training and safe access. Leave those to us.

What extract fan cleaning looks like in Kemprow
There are about 26 restaurants, cafés and works canteens and about 8 takeaways and sandwich shops in and around Kemprow, up to about a mile and a half out, according to the Food Standards Agency’s register. Any of those kitchens with a canopy relies on a fan that gathers grease as it runs. Environmental health officers from Hertsmere council inspect food businesses in Kemprow. They look at how clean the premises and equipment are, and the kitchen extract is part of that. A TR19® certificate and photo report after each clean gives you a record to show an inspector. The fire and rescue service for Kemprow is Hertfordshire Fire and Rescue Service. Fire and rescue authorities enforce the Fire Safety Order in most non-domestic premises, and in a kitchen that fire risk includes the grease in the extract.
School kitchens, at schools like Fair Field Junior School for example, are typically cleaned in the holidays so no lunches are lost. Older buildings often hide long, awkward duct runs, and if you run a kitchen at a historic venue in the area (High Elms Manor is about 2.7 miles north-west), access may need planning.

Why deal with it now?
The fan is part of the fire path. A TR19 clean that left out the fan wouldn’t cover the whole system, and insurers asking for TR19 cleaning expect the full system. It’s simpler to plan the work at Kemprow now than to arrange it in a hurry later.
When the work has to happen, how we reach it and how big the site is all affect the cost. Each of those is built into the quote and give you a fixed price before any work starts.

Questions from Kemprow
Do you cover smaller places like Kemprow?
Yes. Kemprow is within the area we cover across London and the South East. A survey first, from pictures or a visit, means we arrive with the right kit.
Which fire and rescue service is responsible for Kemprow?
Fire safety enforcement in Kemprow is handled by Hertfordshire Fire and Rescue Service. A recent cleaning certificate and a note of the next clean date show that grease in the extract is being managed.
How often does the fan need cleaning?
At least as often as the rest of the extract, which BESA guidance sets by daily cooking hours: from 3-monthly for heavy use to 12-monthly for light use. Some fans need attention sooner.
Can you work evenings and weekends?
Yes. Much of our work happens in the evening, overnight or at weekends, so the site does not lose a service.
How much notice do you need?
The more notice, the better, especially for out-of-hours work. We normally quote within one working day, and there’s a 24/7 line for emergencies.
How long is a fan clean?
That depends on the fan’s size, its position and how much grease there is. As a guide, it takes an hour or two for one fan, longer when it’s hard to reach.
Do you need to turn the fan off to clean it?
We isolate the fan, so the kitchen cannot cook while we work. That is why fan cleans are done out of hours, and the kitchen is ready when we leave.
Can the fan be cleaned between full cleans?
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.

What happens on the day
We’re used to working while the site is closed. A lot of visits happen overnight or at weekends, so a kitchen or building can carry on as usual the next day. The visit itself takes a couple of hours per fan, depending on its size and the build-up. A few pictures of the system help us make the most of a visit to a place like Kemprow.
- The fan is found and its type, access and isolation checked.
- It’s isolated so it can’t run while we work.
- Grease is scraped off the impeller blades and casing.
- The fan is degreased, taking care around the motor.
- It’s closed up, run, checked and photographed for the report.
Before we arrive
- Agree a time when the area can be out of use
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
- Let us know about parking and loading

How the job changes from site to site
Impellers and blades
The impeller is the spinning part that moves the air, and grease builds up on them unevenly. An uneven coating throws it off balance, so it’s cleaned carefully blade by blade.
Fan housings and motors
Inside the casing, grease is thrown onto the walls. We clean it along with the blades.
