Knowle kitchens: local notes
According to Food Standards Agency records, there are about 3 pubs and bars in and around Knowle, up to about a mile and a half out. Breakfasts, bar meals and functions all put grease into the extract wherever they’re cooked. Hampshire and Isle of Wight Fire and Rescue Service covers Knowle. Its fire safety officers can audit commercial kitchens, and grease in the extract is part of a kitchen’s fire risk. Kitchens in Knowle get their food hygiene inspections from Winchester City council. 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.
A hall kitchen that only cooks for events, whether near Church of St Francis or elsewhere in Knowle, still needs its extract cleaned, just less often. Bursars and site managers at schools such as Orchard Lea Infant School tend to book extract cleaning for when the kitchen is empty.
Knowle is about 2 miles north of Fareham, in Hampshire. From the centre of Knowle to the outskirts, extract fan cleaning is available to all kinds of commercial premises, from small sites to large estates. Our area takes in 683 places across Hampshire, from busy centres to quieter spots. You can also see our page for Portsmouth, about 7 miles away.

Extract fan cleaning for kitchens and businesses in Knowle
The extract fan is the heart of the system: it pulls air from the canopy, through the duct and out of the building. Whatever grease slips past the filters and duct reaches the fan, and that’s what we clean. The work covers fan housings, in-line fans and centrifugal fans, and common reasons people get in touch are grease around the motor and its mounts and a fan shaking on its mounts.
Somewhere as small as Knowle, commercial kitchens are few: perhaps a pub, a school or care home kitchen, or a hall used for events. Each still has a canopy and duct that collect grease.
Nothing is signed off by word of mouth: a dated report with pictures of the work, and for TR19® Grease cleans, a certificate issued through the BESCA VHE portal. It shows what was done and what, if anything, couldn’t be reached.

Do you need extract fan cleaning in Knowle?
Grease on a fan is a fire risk, in Knowle as anywhere. A fire in the duct can reach the fan and the grease around it, and a hot, struggling motor does not help.
The symptoms we’re asked about most include:
- Fat spreading onto the roof or wall by the fan
- A fan that hums, whines or rumbles
- A heavily greased fan housing
- An extract fan that vibrates or rattles
Healthcare kitchens, like those at hospitals such as Knowle Hospital (about less than half a mile north-east), often cook for long hours, which puts them in BESA’s heavier-use bands.

What extract fan cleaning can’t fix
Some problems need a different service or another trade:

- Electrical faults in the fan’s supply or controls (an electrician’s job)
- A dirty duct upstream of the fan

Knowle: your questions answered
Do you work at weekends in Knowle?
Yes, evening, overnight and weekend work is normal for us. The work in Knowle can fit around your hours. When you call us on 0345 646 2711 or email us, mention when the site is quiet.
Which fire authority looks after Knowle?
It’s Hampshire and Isle of Wight Fire and Rescue Service, which covers Knowle. It’s worth keeping your fire risk assessment, TR19® certificates and photo reports together, ready to show.
What do you do with what you remove?
We contain it and take it with us. Grease, debris and waste water are collected as the work goes on, so it doesn’t spread.
What should I send you?
Just the basics: where it is, what kind of site, when it’s open and the access. Photos and the last report help too. After that, simply call us on 0345 646 2711, or send details by email.
How much notice should we give?
It depends on the time you need and how big the job is. Tell us your preferred dates when you ask for a quote, and if it’s an emergency, call us any time.
What if parts of the system can’t be reached?
They’re marked on the report. In ductwork, new access panels are often the answer, which we can install.
Do you look at the system first?
Yes. Photos often do the job, and larger or hidden systems get a visit.
How do you keep the site clean during the work?
By covering it before any work starts. We keep the work contained and leave the area clean.
Managing agents and facilities teams in Knowle
Multi-site operators often want one contractor and one number. We cover South East England and London, so a run of sites can go into one programme and kept to a regular schedule.
If you look after several sites, we can plan visits across the whole estate and price them together. Each site gets its own report and photos, so records stay tidy.
Keeping the system healthy
Think of this as the after-treatment advice, short and simple:
- Report grease escaping from the fan
- Notice when the fan starts to sound different
- File the fan’s report with your other records
- Make sure the fan is included each time
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.
Make sure the fan is reachable. A fan that can be reached safely is a fan that gets cleaned, whether it’s on a roof, in a ceiling or on a wall.
Staff cleaning versus specialist work
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 is where we come in.
For ventilation and air handling systems, in-house care is mostly about checks: keeping grilles clear, noting unusual noise or smells and logging filter changes. The inside of ducts and units needs a specialist.

How the visit works
Before we leave, we walk the area with whoever is on site. Anything we couldn’t reach or that needs attention is pointed out there and then, and the same goes into the written report. The visit takes an hour or two for one fan, longer when it’s hard to reach. We agree a date with you, plan the drive to Knowle and turn up when the site is quiet.
- First we locate the fan and agree how it’s safely isolated.
- Power to the fan is isolated before anyone touches it.
- Grease is scraped from the impeller blades and the inside of the housing.
- The fan and its surrounds are degreased, keeping clear of the motor’s electrics.
- It’s closed up, run and checked, and pictures go into your report.
Getting ready for the visit
- Arrange a key holder or contact on site
- Tell us where we can park and unload
- Allow time for equipment near the work to be turned off and cool down

Leave it or put it right?
Grease on the fan is grease in the system. TR19® Grease covers the whole extract, fan included and many insurers require the full system to be cleaned to TR19. A planned visit to Knowle is easier to arrange than an emergency callout.
