Extract fan cleaning for kitchens and businesses in Liss Forest
Every kitchen extract depends on its fan: it draws the air through the canopy and ductwork and pushes it outside. Whatever grease slips past the filters and duct reaches the fan, and that is what we clean. If you have a fan left out of previous cleans and thick grease on the impeller and casing, we can put it right.
For a kitchen in or near Liss Forest, the visit is planned around opening hours and the journey, and the clean covers the whole system, as it would anywhere: canopy to discharge, then a TR19® certificate and a photo report.
Our accreditations include CHAS, SafeContractor and ISO 9001, and we’re fully insured. We’re also a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, trading since 2009.

How the job changes from site to site
Roof-mounted fans
Grease can escape from a roof fan onto the surrounding surface, so the outlet area is checked too. We note any grease around the fan.
Wall fans
The wall around a wall fan can be stained with grease. We clean the fan and check the outlet.
What else we do in Liss Forest
Grease, kitchens and Liss Forest
The FSA’s data shows about 4 bars, pubs and nightclubs registered in and around Liss Forest, up to about a mile and a half out. A pub or hotel kitchen that cooks every day builds up grease in its extract like any other. Liss Forest is covered by Hampshire and Isle of Wight 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. Environmental health officers from East Hampshire council inspect food businesses in Liss Forest. The cleanliness of the kitchen and its equipment, extraction included, is part of what they check. Our report lists what was cleaned and when, which is useful to have ready.
Commuter trade near Liss station can mean long cooking hours, and long hours put a kitchen into BESA’s more frequent cleaning bands. Term dates shape school work: for a school like Liss Infant School, an extract clean fits neatly into a half-term or summer break.

Honest limits
Extract fan cleaning can’t fix everything, and we’ll tell you before any work starts. It doesn’t solve:
- A fan that’s too small for the system (a design question)
- A cracked or broken impeller (it needs replacing)
- Grease in the duct and canopy before the fan (those need a full TR19 clean)
Not sure which it is? You can ring 0345 646 2711, or send details by email and we will tell you honestly.
What the work covers
- Centrifugal fans
- Roof-mounted fans
- Discharge points
- Fan housings
- Axial fans
- In-line fans
How it works
At the end of the visit, someone from your team can look over the work with us. We point out anything that couldn’t be reached or needs a follow-up, and it goes on the report too. The visit takes an hour or two for most single fans. If you can send pictures, we can arrive in Liss Forest knowing what to expect.
- First we locate the fan and agree how it’s safely isolated.
- With the fan isolated, the housing is opened.
- Grease is scraped from the impeller blades and the inside of the housing.
- We degrease the fan and housing, taking care around the motor.
- The fan is put back into service, checked and photographed.
Preparing for the visit
- Make sure equipment near the work can be switched off and left to cool
- Find the previous report, if there is one
- Arrange a key holder or contact on site

Questions from Liss Forest
Is Liss Forest within the area you cover?
Yes, Liss Forest is part of our area, however small the site. Photos of the system and directions to the site help us plan the visit.
Can the work in Liss Forest be done at night or at weekends?
Yes, nights and weekends are routine for us. The work in Liss Forest can fit around your hours. Let us know the hours you’re closed and we will book within them.
Do you have a 24/7 line?
Yes, 24/7. Our office is open from 8am to 6pm on weekdays, with the emergency line covering every other hour.
Is TR19 cleaning required by law?
No, not in itself. TR19® is the benchmark insurers, fire officers and EHOs check against, and many insurers ask for proof of cleaning to it. The legal duty sits in the Regulatory Reform (Fire Safety) Order 2005, which applies in England and Wales.
What is TR19?
TR19® is the BESA specification for keeping ventilation systems clean. TR19® Grease, a standalone specification since 2019, covers grease in kitchen extract systems, and TR19® Air covers general supply and extract systems.
Should the extract fan be cleaned as part of TR19?
Yes, it should be. A TR19 Grease clean covers everything from canopy to discharge, and the fan sits right in that path, so it’s cleaned too.
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.
Is it safe to clean the fan while the kitchen is open?
We always isolate the fan first, so it cannot run during the clean. That means the extract is off, so we clean while the kitchen is closed.
Signs you need extract fan cleaning in Liss Forest
A fan in Liss Forest builds up grease at a rate set by the kitchen, not the location: how many hours a day the kitchen runs and what it cooks. 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 coated in grease inside its housing
- Hot, greasy smells near the fan
- Weak extraction at the canopy
- Grease escaping from the fan outlet
Where a hall near St Saviour's, or anywhere in Liss Forest, hosts lunch clubs or events, its extract gathers grease just as a café’s does.
What to look for in a quote
- Whether they’re fully insured
- What happens if part of the system cannot be accessed
- Whether VAT is included
- Whether the price is fixed
Keeping the system healthy
Results last longer with the right care. Here’s what we suggest:
- Never cook with a filter missing
- Watch for grease marks around the outlet
- Report rattles or humming early
- Note any drop in extraction at the canopy
File the photo report with your other extract records. It gives a dated record of the fan’s condition, which helps if anything changes later.
Stick to the interval for the full extract. A fan cleaned with the rest of the system on time rarely gets badly coated, in line with BESA guidance.
Fixed quotes for extract fan cleaning in Liss Forest
The price is fixed before any work begins. It’s based on:
- Whether several sites go on one quote
- How big the system is
- The condition we find in the survey
- Site requirements such as sign-in and permits
You won’t find a price list here, because each job is priced on what it involves. For a fixed quote, call us on 0345 646 2711 or send us an email, and we’ll talk you through it.
What we need to know
A few details help us quote accurately. When you get in touch, it helps to send:
- Problems your staff have spotted
- Detail shots of panels, filters and grilles
- The times we could work without disrupting the site
- The roof, plant room or outside wall the system runs to
The quickest way to a quote is to send photos: wide shots of the system, close-ups of anything that worries you and how we’d get to it. Tell us what kind of site it is and when it’s open, and we can price many jobs without a visit.
Leave it or put it right?
Vibration from an unbalanced impeller does not stay small. It can wear the bearings and lead to failure and a kitchen can’t cook safely without extraction. Cleaning it early is far less disruptive. Our emergency line runs 24/7, but a planned visit to Liss Forest is calmer for everyone.
Every site is different, so each one gets its own fixed quote. Size, access, the condition of the system and when we can work all play a part.
