Walkern: your questions answered
Who carries out food hygiene inspections in Walkern?
Kitchens in Walkern are inspected by East Hertfordshire council’s environmental health officers. It helps to keep the extract cleaning records with your food safety paperwork, so they’re ready if asked for.
Can you come to Walkern after we close?
Yes, out-of-hours work is a big part of what we do. The work in Walkern can fit around your hours. When you ring 0345 646 2711 or send us an email, mention when the site is quiet.
What’s TR19?
TR19® is BESA’s specification for ventilation hygiene. TR19® Grease, a standalone specification since 2019, covers grease in kitchen extract systems, while TR19® Air covers other supply and extract ductwork.
Do you need to turn the fan off to clean it?
With the fan isolated, the extract is not running. That’s why fan cleans are done out of hours, and the kitchen is ready when we leave.
Can you fix a fan that is worn out?
Cleaning removes grease, but it cannot fix worn parts. Where the fan needs repair or replacement, we can do that too, with a fixed quote first.
Do you offer maintenance contracts?
Yes. Send details of the systems and how they’re used, and we’ll suggest a schedule and quote for it.
What’s the cleaning interval for an extract fan?
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.
Are you fully insured?
Yes. We carry full insurance, and we have been trading since 2009.
Extract fan cleaning for kitchens and businesses in Walkern
Not all extract fans are the same: 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 the survey shows us how to reach it. If you’re dealing with a noisy fan that has got louder over time and a fan that has never been cleaned, we can help.
For a kitchen in or near Walkern, the visit is planned around opening hours and the journey, 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.
The sign-off is always in writing: a dated report with pictures of the work, and for TR19® Grease cleans, a certificate issued through the BESCA VHE portal. Any parts we couldn’t reach are recorded on it too.

Part by part
Roof-mounted fans
A roof fan sits in cooler air, so grease can settle heavily. The impeller and housing are scraped and degreased.
Wall fans
With little duct before them, wall fans collect grease fast. They may need cleaning as often as the canopy, which grease readings will show.
What affects the cost of extract fan cleaning
We quote each job individually. This is what makes a difference:
- Working hours and out-of-hours timing
- The size of the system
- Site requirements such as sign-in and permits
- How easy every part is to reach
No two sites are the same, so we price each one individually. The size of the job, how we reach it, its condition and the working hours all play a part.
What we need to know
When you contact us, these details help:
- The times we could work without disrupting the site
- Your last certificate, test record or report
- Where the site is and what kind of site it is
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
Every quote begins with a look at the system, from your photos and details or, where that is not enough, a survey on site. After that, you get a fixed price for the work so you know the cost before we start.
Honest limits
We’ll always give you a straight diagnosis, so here’s what this work can’t put right:
- An undersized fan that can’t cope
- A fan that will not start
- Damaged fan blades
If you are not sure, just call 0345 646 2711 or drop us a line and we will give you a straight answer before booking.

What else we do in Walkern
Why it’s worth doing now in Walkern
Grease on a roof fan can also escape outside. It marks the area around the outlet and leaves more fuel outside, which is one more reason to keep it clean. Planning a trip to Walkern ahead is easier for everyone than a rushed one.
Combining work into one visit or one programme often makes better use of the time. Tell us about everything you’d like looked at and we’ll price it together.

Grease, kitchens and Walkern
Walkern sits within the area of Hertfordshire Fire and Rescue Service. Its fire safety officers can audit commercial kitchens, and grease in the extract is part of a kitchen’s fire risk. Environmental health officers from East Hertfordshire council inspect food businesses in Walkern. They look at how clean the premises and equipment are, and the kitchen extract is part of that. Our report lists what was cleaned and when, which is useful to have ready.
Aston Bury, about 2.9 miles south, is one of the historic houses near Walkern; if you run event catering at a venue like that, cleans can be booked between functions. Bursars and site managers at schools such as Walkern Primary School tend to book extract cleaning for when the kitchen is empty.

In-house cleaning or a specialist?
Keep a record of what your team does. A simple log of filter washes, wipe-downs and checks helps show that the system is managed between specialist visits, alongside our reports.
When your team notices a problem 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.
The process
We are 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. Somewhere as small as Walkern, the date and timings are agreed with you well before the day.
- The fan is found and its type, access and isolation checked.
- It’s isolated so it can’t run while we work.
- We scrape the heavy grease from the blades and housing.
- Blades, housing and surrounds are degreased with care around the electrics.
- We reassemble, run and photograph the fan.
How to prepare
- Tell us where we can park and unload
- Move anything stored near the system
- Let us know when the site is closed or quiet
How to get a quote
There’s no standard price list, because no two systems are the same. Instead, we look at your site first, from photos or a survey, then send a fixed quote. To get going, phone us on 0345 646 2711, or email photos.
Advice
Common problems we fix in Walkern
A fan collects more grease when the filters let more through. Missing, damaged or badly fitted filters let grease travel the whole system, so the fan takes far more than it should.
Any of these means the system needs a check-up:
- Fat spreading onto the roof or wall by the fan
- A fan motor running hot under a coat of grease
- Weak extraction at the canopy
- Thick grease on the impeller and casing
Church and community hall kitchens, near Parish Church of St Mary the Virgin or anywhere around Walkern, are easy to forget, but their extracts collect grease like any other.
