Liss questions
Do you cover smaller places like Liss?
Yes, Liss is part of our area, however small the site. Let us know about access, parking and anything unusual about getting there when you book.
Who would carry out a food hygiene inspection at a kitchen in Liss?
Kitchens in Liss are inspected by East Hampshire council’s environmental health officers. Have your latest TR19® certificate and photo report to hand, as an officer may ask how the extract is maintained.
Do you provide a report after cleaning the fan?
Before and after pictures go into a report, along with notes on the fan’s condition. A full clean adds a TR19 certificate from the BESCA Vent Hygiene Elite portal.
Does the law say we must follow TR19?
No. TR19® itself isn’t law; it’s a BESA specification. The law is the Regulatory Reform (Fire Safety) Order 2005, which makes the responsible person assess and reduce fire risk, and TR19® is the benchmark for showing that grease in the extract is under control.
Do you work out of hours?
Yes. Evenings, nights and weekends are normal working hours for us, so you do not have to close during trading.
Where does the waste go?
It leaves the site with us at the end of the visit. During the work, it’s contained so the area stays clean.
How far ahead should we book?
Earlier is better, particularly for night and weekend visits. We usually quote within one working day, and emergencies are covered by our 24/7 line.
Is it safe to clean the fan while the kitchen is open?
We isolate the fan, so the kitchen cannot cook while we work. We work evenings, overnight or weekends, and the kitchen is ready when we leave.

Common problems we fix in Liss
A greasy fan in Liss is fuel at the end of the duct. A fire in the duct can reach the fan and the grease around it, and a hot, struggling motor does not help.
Signs it’s time to call us include:
- Less air being pulled from the kitchen
- A fan coated in grease inside its housing
- Hot, greasy smells near the fan
- A fan that hums, whines or rumbles
If you run a church or community hall kitchen, near Church of St Mary or elsewhere in Liss, its extract still collects grease from every lunch and event.

- When the next visit should be, and why
What happens on the day
We work around your opening hours, not the other way round. We book the visit for a time the area is closed, whether that is 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 site near Liss usually has room to park, so the questions are about access to the system and your hours.
- The fan is found and its type, access and isolation checked.
- It’s isolated so it cannot run while we work.
- We scrape the heavy grease from the blades and housing.
- Blades, housing and surrounds are degreased with care around the electrics.
- It’s closed up, run, checked and photographed for the report.
Preparing for the visit
- Tell us about site rules, permits or sign-in
- Agree a time when the area can be out of use
- Let us know about parking and loading
Getting a quote
Getting a quote doesn’t take long. Call or email with a few details and you will normally have a fixed price within one working day. Where a survey is needed, we arrange a time that suits the site.
Related advice
Between visits
Here’s the after-treatment advice, short and simple:
- Watch for grease marks around the outlet
- Don’t turn the fan off mid-service
- Leave a clear route to the fan
- Never cook with a filter missing
A full system clean includes a TR19 certificate from the BESCA Vent Hygiene Elite portal. A fan-only clean is recorded in the photo report.
The fan stays cleaner when less grease gets past the canopy. Clean, well-seated filters are the fan’s first protection, and replace any that are damaged.
When it’s something else
In fairness, some problems need a different fix:
- A faulty speed controller or isolator
- A cracked or broken impeller (it needs replacing)
- Grease in the canopy and ductwork
Not sure which it is? You can call us on 0345 646 2711, or email photos and we will tell you honestly.

Managing agents and facilities teams in Liss
Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person must assess and reduce fire risk, which may be the employer, owner, landlord, FM or managing agent. With shared responsibility, good records help everyone.
Records are where multi-site compliance often slips. Every visit ends with a dated report and pictures, ready to show insurers, fire officers or EHOs.

Why deal with it now?
Cleaning the fan in Liss now is a short job: the work takes a couple of hours per fan, depending on its size and the build-up. Waiting adds vibration, wear and a harder clean. A site near Liss that has to close at short notice is hard to cover for.
Leaving it longer rarely makes the work cheaper. 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, call us on 0345 646 2711, or send details by email and we will give you an honest view and a fixed quote.

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.
Wall fans
Smaller kitchens may extract through a fan on an outside wall. We isolate it, then clean the blades and housing.
Extract fan cleaning in Liss: the local picture
The FSA’s food hygiene register includes about 4 pubs and bars within 1.5 miles or so of the middle of Liss. A pub or hotel kitchen that cooks every day builds up grease in its extract like any other. Kitchens in Liss get their food hygiene inspections from East Hampshire council. Extraction counts as kitchen equipment, so its condition can come up on the day. A TR19® certificate and photo report after each clean gives you a record to show an inspector. Fire safety in Liss falls to Hampshire and Isle of Wight Fire and Rescue Service. In most workplaces, including commercial kitchens, it’s the fire and rescue authority that enforces the Fire Safety Order.
Commuter trade near Liss station can mean long cooking hours, and long hours put a kitchen into BESA’s more frequent cleaning bands. If you look after a school kitchen, at a school such as Liss Infant School or anywhere near Liss, the holidays are the usual time for a TR19® clean.
