Extract fan cleaning in Leavesden, done properly
Every kitchen extract depends on its fan: it pulls air from the canopy, through the duct and out of the building. Grease that gets past everything else ends up on its blades and housing and we clean it off. We are often asked to deal with grease around the motor and its mounts and a fan shaking on its mounts, across discharge points, in-line fans and roof-mounted fans.
In a smaller place like Leavesden, many kitchens sit in older buildings or later extensions, where the duct may cross a roof void or climb an outside wall. Long horizontal runs like that hold grease and need access panels to reach.
It’s worth checking any contractor’s accreditations. We’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we hold CHAS, SafeContractor and ISO 9001, and we’re fully insured.

How it works
The visit has three parts: getting the area ready, doing the work and signing it off. Getting ready means protecting surfaces and switching off what needs to be off, while signing off means the written report and photos. The middle part takes longest, which takes a few hours where there are several fans or heavy deposits. We plan the journey to Leavesden and bring what the job is likely to need.
- Diagnosis first: we look for grease, noise and vibration.
- With the fan isolated, the housing is opened.
- Each blade is cleaned so the impeller runs evenly.
- Housing, outlet and the area around the motor are cleaned.
- We run the fan and note its condition in the photo report.
Preparing for the visit
- Agree a time when the area can be out of use
- Mention any sign-in, permit or induction we need
- Find the previous report, if there is one

Related advice
What else we do in Leavesden
Do you need extract fan cleaning in Leavesden?
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.
Signs it’s time to call us include:
- Vibration from an unbalanced impeller
- A fan left out of previous cleans
- A fan coated in grease inside its housing
- Weak extraction at the canopy
If you run catering at a healthcare site, such as a hospital like Leavesden Hospital about 0.6 miles north-west, the extract may need cleaning more often than a part-time kitchen.

Why deal with it now?
Grease on a roof fan can also escape outside. That stains surfaces and can add to the fire risk outside the building, which is one more reason to keep it clean. A site near Leavesden that has to close at short notice is hard to cover for.
When the work has to happen, how we reach it and how big the site is can all change the price. We take each of them into account and give you a fixed price before we start.

How the job changes from site to site
Kitchens with long cooking hours
Long cooking hours mean more grease reaches the fan. BESA guidance sets at least 3-monthly cleaning for that level of use, fan included.
Wall fans
A wall fan pushes the air straight outside. It’s isolated, opened and cleaned inside and out.
Managing agents and facilities teams in Leavesden
Running several sites is easier with one contractor. We work across London and the South East, so a run of sites can go into one programme and kept on a regular cycle.
The Fire Safety Order 2005 puts the duty to manage fire risk on the responsible person, which may be the employer, owner, landlord, FM or managing agent. With shared responsibility, good records help everyone.
What extract fan cleaning looks like in Leavesden
Look up Leavesden on the FSA’s food hygiene register and you’ll find about 40 restaurants, cafés and works canteens and about 24 sandwich bars and takeaways in and around Leavesden, up to about a mile and a half out. The fan at the end of each of those extracts collects grease that slows it and wears the motor. Environmental health officers from Three Rivers council inspect food businesses in Leavesden. An officer looking round a kitchen will see the canopy, and grease there is hard to miss. A dated certificate in the maintenance file answers the question before it’s asked. Leavesden is covered by 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.
Bursars and site managers at schools such as Alban Wood Primary School and Nursery tend to book extract cleaning for when the kitchen is empty. Historic houses near Leavesden, such as High Elms Manor about 0.4 miles north-east, are a reminder that older buildings with event kitchens can have long, awkward duct routes.

Staff cleaning versus specialist work
Logging matters as much as cleaning. A dated log of in-house cleaning and checks helps show that the system is managed between specialist visits, alongside 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.
Leavesden questions
Can the work in Leavesden be done at night or at weekends?
Yes, out-of-hours work is a big part of what we do. That way a site in Leavesden doesn’t have to lose a day’s trading. Tell us your opening hours when you ask for a quote.
Can you get to a site in Leavesden?
Yes, smaller places are covered as well as towns. The journey is planned ahead, so a few details about the route help.
Is TR19 a legal requirement?
Not in itself. TR19® is the benchmark insurers, fire officers and EHOs check against, 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.
Who is the responsible person?
The law calls them the responsible person. That is generally the employer or the person in control of the premises, and in shared buildings more than one person can have duties. If you’re not sure, check your lease and fire risk assessment.
Is the fan isolated during cleaning?
We always isolate the fan first, so it can’t start while we work. With the extract off, the kitchen cannot cook, so we work out of hours.
Can one contract cover all our sites?
Yes. Send the list of sites and the work at each and you’ll get one fixed quote.
What about areas you cannot get to?
We never leave them off the paperwork. You will know exactly which parts weren’t reached and why, along with a quote to put access in.
How often does the fan need cleaning?
It’s cleaned with the whole extract, from every 3 months for 12 to 16 hours of cooking a day to every 12 months for 2 to 6 hours. Readings may show it needs cleaning more often.
What affects the quote in Leavesden
We quote each job individually. This is what makes a difference:
- The condition we find in the survey
- Parking and loading at the site
- Working hours and out-of-hours timing
- Whether it’s a one-off visit or part of a schedule
Combining work into one visit or one programme can make for a more efficient booking. Tell us about everything you’d like looked at and we will price it together.
Helping us quote
There’s no need for technical detail. It helps if you can send:
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
- Photos showing the whole system and its surroundings
- Detail shots of panels, filters and grilles
- When the site is open and when it’s quiet
Photos are enough for some jobs, while others need a look on site. Big or complicated sites, and systems that are hard to see in photos, get a survey first. Either way, you get a fixed price before work begins.
