Extract fan cleaning in Aspenden, done properly
In Aspenden, as everywhere we work, the fan follows a set routine: we isolate it, open the housing, scrape the impeller and degrease the lot. The result is photographed for your records. We are often asked to deal with a smell of hot grease from the extract and grease around the motor and its mounts, across centrifugal fans, fan housings and discharge points.
Rural kitchens often have long, low duct runs through a roof space or along an outside wall, and those horizontal sections are where grease settles. Access, parking and timings are agreed before the day.
For insurers and inspectors, the record counts. So every job comes with a written report and pictures, and grease extract cleans come with a TR19® certificate issued through the BESCA Vent Hygiene Elite portal.

Different parts, different methods
Inline duct fans
An inline fan can be easy to forget because it’s out of sight. We find it during the survey and include it in the clean.
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.
Common problems we fix in Aspenden
Each blade collects a slightly different amount. Over time, that imbalance shakes the fan, wearing bearings and mounts. Left too long, grease turns into wear.
Common reasons sites call us include:
- A fan that has never been cleaned
- Grease around the motor and its mounts
- Less air being pulled from the kitchen
- A smell of hot grease from the extract
Term dates shape school work: for a school like Millfield First and Nursery School, an extract clean fits neatly into a half-term or summer break.
Before you book anyone
- What paperwork you get at the end
- Proof of accreditation you can verify
- Whether the whole system is included, or only the parts that are easy to reach
- Whether the figure could change on the day
Looking after it afterwards
To keep the system working properly between visits:
- Report rattles or humming early
- Check the report shows the fan was cleaned
- Watch for grease marks around the outlet
- Keep access to the fan clear
A full system clean includes a TR19 certificate from the BESCA Vent Hygiene Elite portal. If only the fan is cleaned, the photo report says so.
Run the fan throughout cooking. Grease settles faster when the air stops moving, so keeping it running helps keep it clean.
Common questions in Aspenden
Who carries out food hygiene inspections in Aspenden?
In Aspenden, it’s East Hertfordshire council that carries out food hygiene inspections. How often a business is inspected depends on the risk rating the council gives it, so it’s worth staying ready all year.
Can school kitchens in Aspenden be cleaned in the holidays?
Yes. The holidays are the usual time for school work. The FSA’s register shows about 5 schools and colleges with food registrations within roughly a mile and a half of Aspenden. Just phone us on 0345 646 2711, or send details by email with your term dates and we’ll plan around them.
How much notice should we give?
The more notice, the better, particularly for night and weekend visits. We usually quote within one working day, and emergencies are covered by our 24/7 line.
Do you work in Aspenden?
Yes. We work across Greater London, Surrey, Kent, Sussex, Hampshire, the Isle of Wight, Berkshire, Buckinghamshire, Oxfordshire, Hertfordshire and Essex, Aspenden included.
What happens to the waste?
It leaves the site with us when we go. While we work, it’s kept contained to keep the area clean.
Can you clean the fan on its own?
Yes, if the fan needs it. We’ll often suggest checking the duct too, as a greasy fan usually means a greasy duct, but the choice is yours.
Is the fan included in a TR19 clean?
Yes, a full TR19 clean includes the fan. If a fan can’t be reached, the report says so, so the record is accurate.
What is TR19?
It’s the industry benchmark for cleaning ventilation and kitchen extract systems, written by BESA. It sets out inspection, cleaning and record keeping, and it takes a risk-based approach.
Why act early in Aspenden
Grease on the impeller makes the fan less efficient. Airflow at the canopy drops and the kitchen gets hotter and smokier, while the motor runs under more strain. A planned visit to Aspenden is easier to arrange than an emergency callout.
Every site is different, 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 staff can safely do
Good housekeeping makes our visits easier, not unnecessary. Regular in-house cleaning slows the build-up, but the parts you cannot see still need a specialist at the right interval.
Away from the kitchen, the in-house job is mainly checking: keeping grilles clear, noting unusual noise or smells and logging filter changes. The inside of ducts and units needs a specialist.

The process
On the day, we arrive at the time agreed with you, often in the evening, overnight or at the weekend so the site keeps working. Equipment that has to be off is switched off and allowed to cool first, and floors and nearby surfaces are sheeted. The work itself takes a couple of hours per fan, depending on its size and the build-up. A quick note on how to find the site and where to park makes a visit to Aspenden run smoothly.
- 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.
- We remove the grease from the blades, impeller and casing.
- The fan and its surrounds are degreased, keeping clear of the motor’s electrics.
- It’s closed up, run and checked, and photos go into your report.
Preparing for the visit
- Tell us where we can park and unload
- Clear the space around the work
- Have your last certificate or report to hand
Ask for a quote

Grease, kitchens and Aspenden
There are about 11 restaurants, cafés and canteens and about 7 takeaways and sandwich shops within roughly a mile and a half of the centre of Aspenden, according to the Food Standards Agency’s register. The fan at the end of each of those extracts collects grease that slows it and wears the motor. Fire safety in Aspenden falls to Hertfordshire Fire and Rescue Service. Grease in a kitchen extract is a recognised fire risk, and the fire authority enforces the law on managing it in most commercial premises. In Aspenden, food businesses are inspected by environmental health officers from East Hertfordshire council. They look at how clean the premises and equipment are, and the kitchen extract is part of that. A dated certificate in the maintenance file answers the question before it’s asked.
Church and community hall kitchens, near Parish Church of St Mary or anywhere around Aspenden, are easy to forget, but their extracts collect grease like any other.
