Managing agents and facilities teams in Adeyfield
Multi-site operators often want one contractor and one number. We cover South East England and London, so a run of sites can go into one programme and kept to a regular schedule.
Whether it’s one building or many, you get the same standard: diagnosis, a fixed price, work booked around your hours and a written report with pictures.
How we handle extract fan cleaning in Adeyfield
We’ve been trading since 2009. As a BESCA Vent Hygiene Elite member, we clean to BESA TR19® Grease, and we’re fully insured, with CHAS, SafeContractor and ISO 9001. The work covers roof-mounted fans, fan housings and centrifugal fans, and the jobs we see most are grease around the motor and its mounts and a fan that hums, whines or rumbles.
For a smaller kitchen near Adeyfield, a TR19® clean is the same job as anywhere: canopy, filters, plenum, duct, fan and discharge. The visit is booked around your opening hours, and the journey is planned ahead.
Each visit ends with a written report and photos, so there’s a dated record of the work. Where the work is a TR19® Grease clean, the certificate is issued through the BESCA Vent Hygiene Elite portal.

In-house cleaning or a specialist?
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. That’s our job.
When your team notices a problem between visits, like drips, unusual noise, smells or damaged filters, they should report it rather than try to fix it. We’ll take a look and send you a fixed quote.
When it’s something else
An honest diagnosis matters more to us than a booking, so here’s what extract fan cleaning won’t do:
- Damaged fan blades
- Grease in the duct and canopy before the fan (those need a full TR19 clean)
- A fan that is too small for the system (a design question)
If in doubt, phone us on 0345 646 2711 or drop us a line and we will say what we think before booking.
What the work covers
- Centrifugal fans
- Roof-mounted fans
- Fan housings
- Discharge points
- In-line fans
- Axial fans
What extract fan cleaning looks like in Adeyfield
Food Standards Agency records list about 105 restaurants, cafés and works canteens and about 66 takeaways and sandwich shops within 1.5 miles or so of the middle of Adeyfield. Any of those kitchens with a canopy relies on a fan that gathers grease as it runs. Adeyfield is covered by Hertfordshire Fire and Rescue Service. In most workplaces, including commercial kitchens, it’s the fire and rescue authority that enforces the Fire Safety Order. In Adeyfield, food businesses are inspected by environmental health officers from Dacorum council. An officer looking round a kitchen will see the canopy, and grease there is hard to miss. Our report lists what was cleaned and when, which is useful to have ready.
Bursars and site managers at schools such as Hobletts Manor Infants' School tend to book extract cleaning for when the kitchen is empty. Historic houses near Adeyfield, such as Batchwood Hall about 4.2 miles east, are a reminder that older buildings with event kitchens can have long, awkward duct routes. Where a hall near St Barnabas, or anywhere in Adeyfield, hosts lunch clubs or events, its extract gathers grease just as a café’s does.

What we do, step by step
When we arrive, we check the system against the survey or the pictures you sent. Anything unexpected is raised with you before we go further. From there, it takes an hour or two for most single fans. Tell us when your site near Adeyfield is quiet and the visit will be booked for then.
- We find the fan and check how it’s reached and how it’s isolated.
- The fan is isolated so it can’t start while we work.
- The impeller and the housing around it are scraped clean.
- Blades, housing and the area around the motor are degreased with care.
- We reassemble, run the fan and photograph the result.
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
- Have your last certificate or report to hand
How to get a quote
Quoting starts with a diagnosis, either from photos and details you send or from a site visit. Then we send a fixed price, before any work starts.

Different parts, different methods
Impellers and blades
Grease on the leading edges of the blades cuts the fan’s efficiency. Scraping and degreasing them restores their shape, so the fan can run as intended.
Kitchens with long cooking hours
Kitchens that cook 12 to 16 hours a day put the most grease through their fans. Under BESA guidance, heavy use means cleaning at least every 3 months, fan included.

Why deal with it now?
A greasy fan has to work harder to move the same air. Less air is pulled from the kitchen, so heat and smoke linger, while the motor runs under more strain. A planned visit to Adeyfield fits your hours; an emergency doesn’t.
Working hours, access and the scale of the site can all change the price. Each of those is built into the quote and give you a fixed price before any work starts.
What you get with us
- Survey first, then a fixed quote
- CHAS and SafeContractor accredited, with ISO 9001
- A written report with photos after every visit
- Out-of-hours work and a 24/7 emergency line

Between visits
Once we’ve finished, these simple steps help:
- Don’t turn the fan off mid-service
- Tell us if the extract feels weaker
- File the fan’s report with your other records
- Never cook with a filter missing
A full system clean includes a TR19 certificate from the BESCA Vent Hygiene Elite portal. A fan-only clean is recorded in the photo report.
Run the fan throughout cooking. Air that keeps moving carries vapour out rather than letting it settle, so keeping it running helps keep it clean.
Your questions about extract fan cleaning in Adeyfield
Do you work overnight in Adeyfield?
Yes, nights and weekends are routine for us. It means the site in Adeyfield keeps running as normal. Let us know the hours you are closed and we’ll book within them.
Can a school canteen extract in Adeyfield be done out of term time?
Yes, and it’s the easiest time to do it. With about 29 schools and colleges on the FSA’s register within roughly a mile and a half of Adeyfield, it pays to plan holiday dates ahead. Just give us a ring on 0345 646 2711 or send us an email with your term dates and we’ll plan around them.
How long is a fan clean?
It takes a couple of hours per fan, depending on its size and the build-up. We will confirm the time when we quote.
Do you have a 24/7 line?
Yes. Our emergency line runs 24/7 for anything that cannot wait until a planned visit. Ring any time and tell us what’s happened.
Can one contract cover all our sites?
Yes. Send the list of sites and the work at each and we will quote them together.
What if parts of the system cannot be reached?
They’re marked on the report. In ductwork, new access panels are often the answer, which we can install.
Does the law say we must follow TR19?
Not in itself. Insurers, fire officers and EHOs look to TR19® as the benchmark, and many insurers ask for proof of cleaning to it. The legal duty sits in the Regulatory Reform (Fire Safety) Order 2005 in England and Wales.
What is TR19?
TR19® is BESA’s specification for ventilation hygiene. TR19® Grease, a standalone specification since 2019, covers grease in kitchen extract systems, and TR19® Air covers general supply and extract systems.
