Extract Fan Cleaning in Cottered
Cleaning of kitchen extract fans, impellers, fan housings and discharge points for Cottered, with a survey first and a report with photos at the end. Ask us for a fixed quote.
- An extract fan that vibrates or rattles
- Grease around the motor and its mounts
- A fan left out of previous cleans
Multi-site and managed buildings
Facilities teams in offices, schools and healthcare sites book us too across Hertfordshire. Larger estates can be phased building by building around the people who use them.
When the building owner and the occupier are different, the lease normally sets out who maintains what. We can quote either party and send the paperwork to whoever needs it.
How we handle extract fan cleaning in Cottered
Any fan serving a kitchen in Cottered is cleaned the same careful way as anywhere else: isolated first, then opened, scraped and degreased. Your report shows the impeller as we found it and as we left it. We are often asked to deal with an extract fan with no cleaning record and a fan motor running hot under a coat of grease, on roof-mounted fans, in-line fans and axial fans.
In a small place like Cottered, kitchens are often in older or extended buildings, with long single-storey duct runs, where grease settles in the flat sections. We agree access and timings in advance.
Our accreditations include CHAS, SafeContractor and ISO 9001, and we’re fully insured. We are also a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, trading since 2009.

How the job changes from site to site
Fan housings and motors
Some fans use a belt drive. We clean around them and note any wear for your records.
Inline duct fans
An inline fan can be easy to forget because it’s out of sight. The survey makes sure it’s part of the clean.
What we’re called out for in Cottered
Grease builds up unevenly on the blades. Over time, that imbalance shakes the fan, wearing bearings and mounts. Left too long, grease turns into wear.
Common reasons sites call us are:
- An extract fan with no cleaning record
- Hot, greasy smells near the fan
- A fan motor running hot under a coat of grease
- Less air being pulled from the kitchen
If you look after a school kitchen, at a school such as Freman College or anywhere near Cottered, the holidays are the usual time for a TR19® clean.

Our technicians bring everything the work needs, from protective sheeting to tools and access equipment. You only need to give us clear access and switch off what needs to be off. On site, the work takes an hour or two for most single fans. A few photos of the system help us make the most of a visit to a place like Cottered.
- We locate the fan and plan how to reach and isolate it.
- We isolate the power before opening the housing.
- 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
- Dig out any earlier paperwork for the system
- Mention any sign-in, permit or induction we need
- Make sure someone can let us in and lock up afterwards

Fixed quotes for extract fan cleaning in Cottered
Every site gets its own quote. These are the things that affect it:
- Where the site is and how we reach it
- Working hours and out-of-hours timing
- Site requirements such as sign-in and permits
- How many systems or sites are involved
No two sites are the same, so each one gets its own fixed quote. The size of the job, how we reach it, its condition and the working hours all make a difference.
What to send for a quote
Photos and a few facts are often enough to price the work. Send what you can of the following:
- Your last certificate, test record or report
- A few general shots of the system
- Any symptoms, from odd noises to smells or leaks
- Any access panels or hatches you can see
Photos are the quickest way to a quote: the system from a couple of angles, plus any access panels or hatches. Tell us what kind of site it is and when it’s open, and we can price many jobs without a visit.
Staff cleaning versus specialist work
Your own staff can handle the daily basics: wiping down canopy surfaces, cleaning filters and keeping a simple log. What they can’t safely do is clean inside the ductwork, the fan or the risers, and that’s where we come in.
A few tasks are always specialist work: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease need training, the right equipment and safe access. Leave those to us.
Cottered: your questions answered
Which environmental health team covers Cottered?
Food hygiene inspections in Cottered are carried out by East Hertfordshire council. Have your latest TR19® certificate and photo report to hand, as an officer may ask how the extract is maintained.
Is Cottered within the area you cover?
Yes, smaller places are covered as well as towns. Just mention lanes, gates or anything else about the site when you book.
What is TR19?
A BESA specification in two main parts: TR19® Grease for kitchen extracts and TR19® Air for supply and extract systems. It is not law, but it’s the benchmark.
Can you look after several sites?
Yes. Tell us the addresses and what each needs and we’ll quote them together.
Can you set up regular visits?
Yes, of course. Tell us what you have and how it’s used, and we will suggest a schedule and quote for it.
What about areas you cannot get to?
They’re listed in the report, never skipped quietly. You will know exactly which parts weren’t reached and why, and we can quote to improve the access.
Do we need to close while you work?
Not typically. Booking the work out of hours means the site can carry on as normal. Larger jobs can be phased over several visits so parts stay in use.
What’s the cleaning interval for an extract fan?
It depends on how many hours the kitchen cooks in BESA guidance. Heavy use means at least every 3 months, light use at least every 12, fan included.

Aftercare tips
Think of this as the after-treatment advice, short and simple:
- Keep the fan on whenever the range is lit
- Report grease escaping from the fan
- Tell us if the extract feels weaker
- Notice when the fan starts to sound different
Keep the report with the maintenance log and fire risk assessment. It shows the fan’s condition at the time of the clean, which helps if anything changes later.
Stick to the interval for the full extract. Regular full cleans keep the fan from building up heavy deposits, in line with BESA guidance.
