About our extract fan cleaning in Ayot Green
Cleaning removes grease, not wear. If we find worn bearings, a struggling motor or damage to the impeller, we’ll tell you, and we also repair and replace extract fans. You will know whether the fan just needed cleaning or something more. If you have burning smells from the fan area and rough running from the extract fan, we can help, from axial fans, roof-mounted fans and centrifugal fans onwards.
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. We agree access and timings in advance.
Every visit ends with a written report and photos, so you have a record of what was done and when. Where the work is a TR19® Grease clean, the certificate is issued through the BESCA Vent Hygiene Elite portal.

Why act early in Ayot Green
A greasy fan has to work harder to move the same air. Less air is pulled from the kitchen, so heat and smoke linger and the motor works harder. Rural sites can’t always move to another kitchen or room when something fails.
One small site or a whole estate, the quote is built the same way: the work involved, the access and the timing. The price is fixed before work begins.

What your team can do, and what needs us
If your staff spot something between visits, such as dripping grease, a noisy fan, a smell or a filter that won’t come clean, it’s best reported rather than tackled in-house. We can diagnose it and quote.
Some jobs should never be done in-house: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease need training, the right equipment and safe access. That’s our job.
How the job changes from site to site
Wall fans
Grease can mark the outside wall around the fan. The outlet is checked as well as the fan.
Impellers and blades
Coated blades move less air. We clean each blade back to its surface, so the fan can run as intended.
How we price extract fan cleaning
There’s no set price list, because no two systems are the same. What we look at:
- A single visit or a regular plan
- Access, including roofs, risers and ceiling voids
- The number of sites or systems
- Any permits to work or inductions
Several systems or sites on one quote often makes better use of the time. Mention every system or site you need covered, and you will get one fixed quote.
Asking for a quote
To help us quote quickly, please include:
- Your last certificate, test record or report
- The times we could work without disrupting the site
- Any access panels or hatches you can see
- Problems your staff have spotted
We do not publish a price list, because every site is different. We look at your system first, from pictures or on a visit, and then give you a fixed quote. To start, phone us on 0345 646 2711 or drop us a line.
Do you need extract fan cleaning in Ayot Green?
The fan sits at the end of the grease’s journey. The grease that’s left lands on the blades and the casing, and the spinning blades fling it onto the walls of the housing.
These are the problems we see most often:
- Burning smells from the fan area
- A fan motor running hot under a coat of grease
- A fan coated in grease inside its housing
- An extract fan that vibrates or rattles
Church and community hall kitchens, near Church of St Peter or anywhere around Ayot Green, are easy to forget, but their extracts collect grease like any other.
What your quote should include
- What paperwork you get at the end
- When they can work, and whether that is outside your opening hours
- How areas they can’t reach will be recorded
- Proof of insurance
How it works
Our technicians bring everything the work needs, including protection sheets, the right tools and access kit. 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. For a village or hamlet like Ayot Green, tell us about narrow lanes, gates and parking when you book.
- Diagnosis first: we look for grease, noise and vibration.
- Once isolated, we open the fan up.
- The impeller is cleaned blade by blade so it runs balanced.
- We clean the casing, the outlet and around the motor.
- We run the fan and note its condition in the photo report.
How to prepare
- Name a contact who can let us in at the agreed time
- Tell us the best time to work, such as after service or at a weekend
- Mention any parking or loading restrictions
Ask for a quote
Quoting starts with a diagnosis, from your photos and details or, where that isn’t enough, a survey on site. Then we send a fixed price so you know the cost before we start.

When it’s something else
In fairness, there are a few things this work won’t fix:
- Electrical faults in the fan’s supply or controls (an electrician’s job)
- A fan that was never right for the kitchen
- An impeller that’s bent or split
If you are not sure, just call us on 0345 646 2711 or send us an email and we’ll give you a straight answer.
Parts of the system we cover
- Centrifugal fans
- Roof-mounted fans
- Axial fans
- Discharge points

Common questions in Ayot Green
Which fire and rescue service is responsible for Ayot Green?
Fire safety enforcement in Ayot Green is handled by Hertfordshire Fire and Rescue Service. Records of extract cleaning are a sensible thing to have ready if a fire safety officer carries out an audit.
Can school kitchens in Ayot Green be cleaned in the holidays?
Yes, and it’s the easiest time to do it. There are about 14 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of Ayot Green. You can give us a ring on 0345 646 2711 or send us an email with the dates the site is empty.
Do you have a 24/7 line?
Yes, any time. If something urgent happens, like a fan failing or damage after a fire, call our 24/7 line, and we will advise on what to do next.
Who is the responsible person?
In the words of the Fire Safety Order 2005, it’s 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. Your lease and fire risk assessment should make it clear.
Do you need to turn the fan off to clean it?
The fan is isolated before we open it, so it cannot start while we work. That means the extract is off, so we clean while the kitchen is closed.
Are you insured?
Yes. We are fully insured, and we can share the details when you need them.
Can you clean the fan on its own?
Yes, we do. The report will make clear that only the fan was cleaned, so your TR19 records stay accurate. The whole system still needs cleaning at the intervals in BESA guidance.
Can you work evenings and weekends?
Yes, and it’s often the best time. The visit is timed for when the area isn’t in use, whether that’s late evening, overnight or a weekend.

Any of those kitchens with a canopy relies on a fan that gathers grease as it runs. Hertfordshire Fire and Rescue Service covers Ayot Green. In most workplaces, including commercial kitchens, it’s the fire and rescue authority that enforces the Fire Safety Order.

Our report lists what was cleaned and when, which is useful to have ready.
Term dates shape school work: for a school like Monk's Walk School, an extract clean fits neatly into a half-term or summer break. If your kitchen is in a listed or historic building, like the houses around Ayot Green (Digswell House is about 1.1 miles east), fitting access panels needs care.
