About our extract fan cleaning in Knapp
Any fan serving a kitchen in Knapp is cleaned the same careful way as anywhere else: we isolate it, open the housing, scrape the impeller and degrease the lot. The result is photographed for your records. We are often asked to deal with grease stains around the discharge and thick grease on the impeller and casing, on axial fans, fan housings and in-line fans.
In a village or hamlet like Knapp, the kitchens that need extract cleaning are typically a pub, a school, a care home or a hall kitchen, wherever there is one. Every one of them still needs its extract kept clear of grease, whatever the size of the place.
Think of the report as the system’s health record: a dated account with photos of everything we did. For TR19® Grease cleans, the certificate comes through the BESCA Vent Hygiene Elite portal and sits alongside the report.

Keeping the system healthy
To keep the system working properly between visits:
- Look for grease stains near the discharge
- Keep the grease filters clean and in place
- Tell us if the extract feels weaker
- Keep access to the fan clear
The photo report shows the fan before and after cleaning. It notes what was done and anything that couldn’t be reached, along with the recommended next clean date.
Do not run the kitchen with the extract off. Air that keeps moving carries vapour out rather than letting it settle, so keeping it running helps keep it clean.
What your team can do, and what needs us
Staff cleaning does not replace a specialist visit; it supports it. Clean filters and tidy surfaces slow the build-up, but hidden parts of the system still need specialist attention.
Day-to-day cleaning is something your team can do: wiping down canopy surfaces, cleaning filters and keeping a simple log. What they cannot safely do is clean inside the ductwork, the fan or the risers, and that’s where we come in.
Fixed quotes for extract fan cleaning in Knapp
Before we fix a price, we need to know a few things. We check:
- Parking and loading at the site
- What state the system is in
- Whether we need access equipment or extra panels
- A single visit or a regular plan
Combining work into one visit or one programme can make for a more efficient booking. Mention every system or site you need covered and we will price it together.
What to send for a quote
There’s no need for technical detail. It helps if you can send:
- Wide photos of the system and the area around it
- Problems your staff have spotted
- The postcode and the type of business
- Any previous report or certificate
Every quote begins with a look at the system, either from photos and details you send or from a site visit. After that, you get a fixed price for the work, before work begins.
The process
We turn up at the time agreed with you, which is often after service, overnight or at a weekend. Anything that needs to be off for the work is switched off and left to cool before work begins, and the area around the work is covered and protected. On site, it takes a few hours where there are several fans or heavy deposits. Visits to a village like Knapp are booked in advance, at a time that suits whoever runs the site.
- We locate the fan and plan how to reach and isolate it.
- It’s isolated so it cannot run while we work.
- Grease is scraped off the impeller blades and casing.
- The fan is degreased, taking care around the motor.
- It’s closed up, run, checked and photographed for the report.
Before we arrive
- Move anything stored near the system
- Have your last certificate or report to hand
- Arrange a key holder or contact on site
Ask for a quote
Photos are the quickest way to a quote: the system from a couple of angles, plus any access panels or hatches. Tell us what kind of site it is and when it’s open, and many jobs can be priced from that alone.

Knapp questions
Can you work in Knapp outside opening hours?
Yes. We work evenings, overnight and at weekends. The site is handed back ready to open. Let us know the hours you’re closed and we’ll book within them.
Do you work in villages like Knapp?
Yes. Villages and rural sites across the South East are part of our work, Knapp included. Just mention lanes, gates or anything else about the site when you book.
What information do you need?
Some photos and a quick description of the system, with the address and opening hours. If we need more, we will ask.
Is TR19 cleaning required by law?
No. The law sets the duty, and TR19® is the recognised benchmark for meeting it. Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person has to manage fire risk, and many insurers can refuse or reduce a claim without proof of cleaning.
Will we have to shut during the visit?
Not normally. We need the work area to ourselves while we are on site, so we book a time when it would be closed anyway.
Are you fully insured?
Yes. Full insurance covers our work, and we’ve been trading since 2009.
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’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, and TR19® Air covers general supply and extract systems.
Leave it or put it right?
An unbalanced fan gets worse, not better. It can wear the bearings and lead to failure, which may leave the kitchen without extraction. A planned clean beats an emergency. Somewhere as small as Knapp, losing a kitchen or building to a fault is felt by everyone who uses it.
The price reflects the work, not guesswork. That is why we survey first, from pictures or on site, and the price is agreed before work begins.

Kitchen extracts in Knapp
Food Standards Agency records include about 5 pubs, bars and clubs within roughly a mile and a half of the centre of Knapp. Breakfasts, bar meals and functions all put grease into the extract wherever they’re cooked. Kitchens in Knapp get their food hygiene inspections from Test Valley council. Extraction counts as kitchen equipment, so its condition can come up on the day. A dated certificate in the maintenance file answers the question before it’s asked. Fire safety in Knapp falls to 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.
Where a hall near Church of St Mark, or anywhere in Knapp, hosts lunch clubs or events, its extract gathers grease just as a café’s does. Healthcare kitchens, like those at hospitals such as Romsey Community Hospital (about 2.9 miles south-west), often cook for long hours, which puts them in BESA’s heavier-use bands.

Common problems we fix in Knapp
The cooler the air, the more grease drops out, and a fan out on a roof or wall often sits where the air is coolest. That makes it a natural place for grease to settle.
It’s time to book a visit if you see:
- A fan motor running hot under a coat of grease
- Rough running from the extract fan
- A fan shaking on its mounts
- An extract fan with no cleaning record
Bursars and site managers at schools such as Ampfield Church of England Primary School tend to book extract cleaning for when the kitchen is empty.
