What the work involves, part by part
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.
Kitchens with long cooking hours
A long-hours kitchen cannot afford a fan failure. Keeping the fan clean is part of avoiding that, and our 24/7 emergency callout is there if it happens anyway.
How we handle extract fan cleaning in Denvilles
Not all extract fans are the same: roof-mounted units, inline fans within the duct, and wall fans. The way in depends on the type and the survey shows us how to reach it. We are often asked to deal with grease escaping from the fan outlet and a motor area thick with grease, on axial fans, fan housings and discharge points.
Around a smaller place like Denvilles, kitchen extracts tend to belong to pubs, cafés, takeaways and school or care home kitchens. Quieter kitchens still collect grease in the duct, just more slowly, so the interval is set by hours of use and grease readings.
Our accreditations include CHAS, SafeContractor and ISO 9001, and we’re fully insured. On top of that, we’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we have been trading since 2009.

The process
A visit follows the same order every time: sheeting and protection first, isolate whatever needs isolating, do the work, clear away and hand over the paperwork. On site, the work takes a few hours where there are several fans or heavy deposits. Your opening hours decide when we come to Denvilles, not ours.
- Diagnosis first: we look for grease, noise and vibration.
- With the fan isolated, the housing is opened.
- The impeller is cleaned blade by blade so it runs balanced.
- Housing, outlet and the area around the motor are cleaned.
- The fan goes back into service with a report on its condition.
Before we arrive
- Clear loose items from the work area
- Tell us about site rules, permits or sign-in
- Name a contact who can let us in at the agreed time
Ask for a quote
Every quote begins with a look at the system, from your photos and details or, where that isn’t enough, a survey on site. Then we send a fixed price, before any work starts.
Advice
Honest limits
We won’t sell you work that does not address the problem, so here are the limits:
- A fan that won’t start
- A faulty speed controller or isolator
- Grease in the duct and canopy before the fan (those need a full TR19 clean)
If you’re not sure, just call 0345 646 2711 or drop us a line and we’ll give you a straight answer.

Do you need extract fan cleaning in Denvilles?
Fans that are hard to reach are often the ones that get missed. If it wasn’t included in past cleans, it may hold years of grease, and the report will show it.
If you notice any of these, it’s worth a diagnosis:
- Rough running from the extract fan
- Grease stains around the discharge
- A fan left out of previous cleans
- A smell of hot grease from the extract
Kitchens that cook twelve hours or more a day, as some healthcare kitchens do, fall into BESA’s three-monthly minimum; Havant War Memorial Hospital is the nearest hospital to Denvilles, about 1 mile west.

Keeping the system healthy
Here’s the after-treatment advice, in brief:
- Report grease escaping from the fan
- Make sure the fan is included each time
- Listen for new noises or vibration from the fan
- Never cook with a filter missing
When the fan is cleaned as part of a full TR19® Grease clean, a TR19 certificate is issued through the BESCA Vent Hygiene Elite portal. A fan-only clean is recorded in the photo report.
A change in how the fan sounds is worth noting. New noise or vibration often means grease is building on the impeller, and catching it early keeps it a cleaning job.
Kitchen extracts in Denvilles
Denvilles is within about 1 mile of the coast. Salt in the air is hard on rooftop fans, discharge cowls and fixings, so we check them for corrosion as well as grease. The Food Standards Agency lists about 22 pubs, bars and clubs and about 4 hotels and B&Bs as registered food businesses across Denvilles and its immediate surroundings (about a mile and a half). Wherever they cook, the canopy, duct and fan collect grease just as a restaurant’s do. It’s Havant council that sends environmental health officers to food businesses in Denvilles. A greasy canopy or dripping filters are the sort of thing an inspection can pick up. A TR19® certificate and photo report after each clean gives you a record to show an inspector.
Where a hall near St Thomas à Becket Church, or anywhere in Denvilles, hosts lunch clubs or events, its extract gathers grease just as a café’s does. Commuter trade near Warblington station can mean long cooking hours, and long hours put a kitchen into BESA’s more frequent cleaning bands.

Landmarks near Denvilles

Staff cleaning versus specialist work
Keep a record of what your team does. A dated log of in-house cleaning and checks shows an inspector that the system is looked after between visits, alongside our reports.
Your own staff can handle the daily basics: wiping down canopy surfaces, cleaning filters and keeping a simple log. Inside the ducts, risers and fan is specialist work, which is where we come in.
Denvilles: your questions answered
Does the sea air around Denvilles make a difference to extract fan cleaning?
It can. Denvilles is within about 1 mile of the coast, and salt air speeds up corrosion. A fan housing that is rusting near the coast can fail sooner, so it’s worth catching early.
Who inspects food businesses in Denvilles?
That is Havant council, whose environmental health officers carry out food hygiene inspections in Denvilles. It helps to keep the extract cleaning records with your food safety paperwork, so they’re ready if asked for.
Can the fan be cleaned between full cleans?
Yes, if the fan needs it. We’ll often suggest checking the duct too, as a greasy fan normally means a greasy duct, but the choice is yours.
Do you survey before quoting?
Yes. Photos often do the job, while bigger or harder-to-see systems are surveyed on site.
What information do you need?
Just the basics: the address, the site type, your opening hours and how we reach the system. Photos and any previous paperwork make it quicker. After that, simply call us on 0345 646 2711 or drop us a line.
Do you have insurance?
Yes. We’re fully insured, and we can share the details when you need them.
Will I get pictures of the cleaned fan?
Every clean has a photo report, along with notes on the fan’s condition. A full clean adds a TR19 certificate from the BESCA Vent Hygiene Elite portal.
What’s TR19?
TR19® is the BESA specification for keeping ventilation systems clean. Since 2019, TR19® Grease has been a standalone specification for grease in kitchen extract systems, while TR19® Air covers other supply and extract ductwork.
