Typical jobs include a fan that no longer moves enough air and rough running from the extract fan, across centrifugal fans, roof-mounted fans and fan housings.
Work in a small place like North Lee starts with a call to agree access and timings, and the clean covers the whole system, as it would anywhere: canopy, filters, duct, fan and discharge, with a certificate and photo report at the end.

FAQs for North Lee
Do you clean school canteen extracts around North Lee out of term?
Yes, holiday work suits schools best. Food Standards Agency records list about 2 schools, colleges and universities with registered kitchens within about a mile and a half of North Lee. Tell us your holiday dates and we’ll book the visit for when the site is empty.
Which environmental health team covers North Lee?
The local authority for North Lee is Buckinghamshire council, and its environmental health team does the inspecting. Ratings are published by the Food Standards Agency, so a clean extract and good records are worth keeping up.
Will we have to shut during the visit?
Not usually. Visits are timed for when the area is closed, such as overnight or at a weekend, so you keep your normal hours.
What about areas you cannot get to?
The report shows them clearly. Often the fix is extra access, such as new panels in ductwork, and we can fit those.
How much notice should we give?
For planned work, earlier is better, particularly if your next visit is nearly due. For emergencies, we take calls 24/7.
How do you protect the area?
We start with protection: floor sheeting and covers over nearby surfaces and equipment. The area is left tidy, with our waste taken away.
Can you work evenings and weekends?
Yes. Tell us your opening hours when you ask for a quote and we will plan the visit around them.
Can you clean the fan on its own?
Yes, a fan can be cleaned on its own. That helps when the fan needs attention before the next full clean, but it doesn’t replace a full TR19 clean.

The process
Protection comes first: floors, worktops and anything near the work are covered. Then we make the system safe and start. It takes an hour or two for most single fans, and the area is cleaned down before we leave. If the van will struggle with a lane or gateway near North Lee, let us know and we will plan around it.
- 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.
- The fan goes back into service with a report on its condition.
Preparing for the visit
- Clear loose items from the work area
- Mention any parking or loading restrictions
- Make sure equipment near the work can be switched off and left to cool
Ask for a quote
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, the quote is fixed before any work is booked.

What affects the cost of extract fan cleaning
Your quote is based on your site. We consider:
- Whether we need access equipment or extra panels
- Working hours and out-of-hours timing
- How many systems or sites are involved
- The size of the system
You will not find a price list here, because each job is priced on what it involves. Call for a fixed quote, and we will talk you through it.
Helping us quote
To help us quote quickly, send us:
- The roof, plant room or outside wall the system runs to
- The site address and the type of premises
- Close-ups of filters, grilles, hatches or access panels
- The times we could work without disrupting the site
Every quote begins with a look at the system, either from photos and details you send or from a site visit. Then we send a fixed price, before any work starts.
Why act early in North Lee
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. A planned visit to North Lee is easier to arrange than an emergency callout.
Combining work into one visit or one programme often makes better use of the time. Mention every system or site you need covered, and you will get one fixed quote.

When it’s something else
A few issues sit outside what this work can do:
- An undersized fan that can’t cope
- A faulty speed controller or isolator
- Grease in the duct and canopy before the fan (those need a full TR19 clean)
If you are not sure, just ring 0345 646 2711, or email photos and we’ll give you a straight answer.
Parts of the system we cover
- Fan housings
- Discharge points
- Roof-mounted fans
- In-line fans
- Axial fans
- Centrifugal fans
When to call us in North Lee
A greasy fan in North Lee is fuel at the end of the duct. A fire in the duct can reach the fan and the grease around it and an overworked motor runs hotter.
These are the problems we see most often:
- An extract fan that vibrates or rattles
- A noisy fan that has got louder over time
- Fat spreading onto the roof or wall by the fan
- Less air being pulled from the kitchen
Healthcare kitchens can’t easily close, so their extracts are cleaned overnight or between meal services; the nearest hospital to North Lee is Stoke Mandeville Hospital, about 1.7 miles north.

North Lee kitchens: local notes
Look up North Lee on the FSA’s food hygiene register and you will find about 4 restaurants, cafés and works canteens within about 1.5 miles of central North Lee. Any of those kitchens with a canopy relies on a fan that gathers grease as it runs. Buckinghamshire Fire and Rescue Service covers North Lee. 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. Kitchens in North Lee get their food hygiene inspections from Buckinghamshire 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 Church of St Mary or anywhere around North Lee, are easy to forget, but their extracts collect grease like any other. If you look after a school kitchen, at a school such as Stoke Mandeville Combined School or anywhere near North Lee, the holidays are the usual time for a TR19® clean.

Records are where multi-site compliance often slips. Each visit produces a dated report with pictures, so you can show an insurer or inspector what was done at each site.
Different parts, different methods
Wall fans
With little duct before them, wall fans collect grease fast. They may need cleaning as often as the canopy, which grease readings will show.
Kitchens with long cooking hours
Kitchens that cook 12 to 16 hours a day put the most grease through their fans. Under BESA guidance, heavy use means cleaning at least every 3 months, fan included.
