Extract Fan Cleaning in Letty Green

- Thick grease on the impeller and casing
Extract fan cleaning in Letty Green, 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 that’s what we clean. Typical jobs include a fan that no longer moves enough air and grease around the motor and its mounts, on centrifugal fans, axial fans and discharge points.
In a village or hamlet like Letty Green, the kitchens that need extract cleaning are normally a pub, a school, a care home or a hall kitchen, wherever there is one. Each still has a canopy and duct that collect grease, whatever the size of the place.
The paperwork matters as much as the work. Each visit is written up with pictures, listing what was done, anything we couldn’t reach and when the next visit is due. File it in your maintenance log so it’s to hand when an insurer or inspector asks.

Letty Green: your questions answered
Do you work in villages like Letty Green?
Yes. Villages and rural sites across the South East are part of our work, Letty Green included. Photos of the system and directions to the site help us plan the visit.
Can the work in Letty Green be done at night or at weekends?
Yes, nights and weekends are routine for us. The work in Letty Green can fit around your hours. Just call us on 0345 646 2711 or use the quote form with your opening times and we will plan around them.
How long does extract fan cleaning take?
One easily reached fan is quick, while fans on high roofs or in tight voids take longer. It’s done while the kitchen is closed.
What do you do with what you remove?
We contain it and take it with us. We collect grease, debris and waste water as we go rather than letting it spread.
Which sectors do you work in?
All kinds of commercial and public premises: from restaurants, pubs and hotels to schools, hospitals, care homes, offices, shops and food production sites. Work is timed around how each site runs.
Is TR19 cleaning required by law?
No. The law sets the duty; TR19® is the benchmark used to show it’s met. Under the Fire Safety Order 2005, the responsible person must reduce fire risk, and without records, many insurers may refuse or reduce a claim.
Do you provide a report after cleaning the fan?
You get a photo report with before and after photos of the fan. Full system cleans come with a TR19 certificate as well.
How do you keep the site clean during the work?
We start with protection: sheeting over floors, worktops and anything close to the work. We tidy up and take our waste away before we leave.
Letty Green kitchens: local notes
We cover Letty Green, about 20 miles from central London, as part of our work across London and the South East. Visits are booked around your hours, evenings and weekends included. Food hygiene inspections in Letty Green are the job of East Hertfordshire council’s environmental health team. 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.
Term dates shape school work: for a school like Hertingfordbury Cowper Primary School, an extract clean fits neatly into a half-term or summer break. Historic houses near Letty Green, such as Hatfield House about 3.4 miles south-west, are a reminder that older buildings with event kitchens can have long, awkward duct routes.

The process
Your trading hours come first. We book the visit for a time the area is closed, whether that’s an evening, overnight or a weekend. When the team arrives, the work area is protected and the relevant equipment is switched off to cool, and the work takes a few hours where there are several fans or heavy deposits. A quick note on how to find the site and where to park makes a visit to Letty Green run smoothly.
- We start by checking where the fan sits and how to isolate it.
- The fan is isolated so it cannot 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.
- The fan is put back into service, checked and photographed.
Getting ready for the visit
- Agree a time when the area can be out of use
- Mention any locked doors, roof access or ceiling voids
- Let us know about permits to work or site inductions

Photos are the quickest way to a quote: wide shots of the system, close-ups of anything that worries you and how we’d get to it. Add the site type and your opening hours, and we can price many jobs without a visit.

What a clean won’t put right
We’ll always give you a straight diagnosis, so here’s what this work cannot put right:
- An impeller that’s bent or split
- Wiring faults to the fan
- A fan that is too small for the system (a design question)
Not sure which it is? You can give us a ring on 0345 646 2711 or send us an email and we’ll tell you honestly before you book.
Where we work
- Fan housings
- Axial fans
- Discharge points
- In-line fans
- Centrifugal fans
- Roof-mounted fans
How we price extract fan cleaning
A fixed price needs a few facts first. We look at:
- Any permits to work or inductions
- Travel, parking and unloading
- The number of sites or systems
- When the work can happen, such as evenings, overnight or weekends
Putting the work off seldom saves money. Build-up, wear and faults tend to get worse, not better, and a neglected system can mean more work. If you are not sure what’s needed, phone us on 0345 646 2711 or drop us a line for straight advice and a fixed quote.
What to send for a quote
Before you ask for a quote, gather:
- The site address and the type of premises
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- A few general shots of the system
- Problems your staff have spotted
Want a quote for extract fan cleaning? Please phone us on 0345 646 2711 or use the quote form and tell us about the site. We’ll explain what we’d do and send a fixed quote before anything is booked.
Keeping the system healthy
Once we’ve finished, these simple steps help:
- Keep the fan on whenever the range is lit
- Make sure the fan is included each time
- Report grease escaping from the fan
- Report rattles or humming early
When we’ve finished, the fan is reassembled and run. Anything we notice, like noise, vibration or a worn part, goes on the report, so you can plan any repair.
Keep the route to the fan clear. Clear access means it’s never left out of a clean, whether it’s on a roof, in a ceiling or on a wall.
Why it’s worth doing now in Letty Green
Vibration from an unbalanced impeller doesn’t stay small. It can wear the bearings and lead to failure, which may leave the kitchen without extraction. Cleaning it early is far less disruptive. If the system at a site near Letty Green fails, there may be nowhere nearby to move to.
No two sites are the same, so we price each one individually. Size, access, the condition of the system and when we can work all play a part.

How the job changes from site to site
Fan housings and motors
Inside the casing, grease is thrown onto the walls. It’s scraped and degreased with the impeller.
Roof-mounted fans
Grease can escape from a roof fan onto the surrounding surface and we check the area around the outlet. We note any grease around the fan.
When to call us in Letty Green
A fan in Letty Green builds up grease at a rate set by the kitchen, not the location: daily hours and the amount of frying and grilling. Under BESA guidance, the whole system, fan included, needs cleaning at least every 3, 6 or 12 months depending on daily hours.
Signs it’s time to call us include:
- A fan motor running hot under a coat of grease
- An extract fan that vibrates or rattles
- A smell of hot grease from the extract
- A fan that has never been cleaned
A hall kitchen that only cooks for events, whether near St John's Church or elsewhere in Letty Green, still needs its extract cleaned, just less often.
Questions to ask before booking

- What hours they’ll be on site
