Kitchen duct cleaning in Knowle
Cooking sends fat-laden vapour into the canopy with every service. As it cools, it clings to the inside of the ductwork and keeps building. That layer will burn, and cleaning the whole system is how you keep it under control. If you are dealing with cleaning needed before an insurance renewal or survey and a kitchen with no current TR19 certificate, we can help. Searching for commercial kitchen extraction cleaning in Knowle? We’ve been cleaning kitchen extracts across the South East since 2009, with a certificate and photo report after every clean.
We clean every reachable part of the system in Knowle: canopy, plenum, filters, ducts, risers and fan, then record anything that couldn’t be reached.
For a kitchen in or near Knowle, the visit is planned around opening hours and the journey, and the clean covers the whole system, as it would anywhere: canopy, filters, duct, fan and discharge, with a certificate and photo report at the end.
Accreditations are easy to claim and worth checking. Ours are BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease, plus CHAS, SafeContractor and ISO 9001, and we’re fully insured.

Common problems we fix in Knowle
Hours of cooking are the biggest factor. Under BESA guidance, heavy use of 12 to 16 hours a day means a clean at least every 3 months, moderate use every 6 months and light use every 12. They are minimums: measured grease levels set the real interval.
Keep an eye out for any of the following:
- Grease smells coming from the extract
- Poor airflow at the canopy
- Extraction mentioned at an environmental health visit
- A TR19 certificate needed for the insurer
If you look after a school kitchen, at a school such as Orchard Lea Infant School or anywhere near Knowle, the holidays are the usual time for a TR19® clean.

What the work involves, part by part
Canopy and plenum
Grease meets the system first at the canopy and the plenum behind the filters. We clean both inside and out, including the filter housing.
Grease filters
A filter that is missing or bent lets grease straight past. We check they fit as they should when we refit them, and flag any that don’t.

What affects the cost of kitchen extract cleaning
Every site gets its own quote. This is what makes a difference:
- Where the site is and how we reach it
- How big the system is
- The times the site is available
- The number of sites or systems
Putting the work off seldom saves money. Build-up, wear and faults tend to get worse, not better, which can make the next visit longer. If you’re unsure, call 0345 646 2711 or drop us a line for straight advice and a fixed quote.
What to send for a quote
The more you tell us, the more accurate the quote. When you get in touch, it helps to send:
- The postcode and the type of business
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- Any access panels or hatches you can see
- A few general shots of the system
To get a fixed quote, call 0345 646 2711 or send us an email with the site type, your trading hours and a short description of the system. Photos and the last report, if you have one, make the quote quicker. We typically come back within one working day.
How the visit works
A visit follows the same order every time: sheeting and protection first, isolate whatever needs isolating, carry out the kitchen extract cleaning, clear away and leave you the report. The visit itself takes a few hours for a small kitchen, longer for a large system. We agree a date with you, plan the drive to Knowle and turn up when the site is quiet.
- You send photos or we visit, and the system is surveyed from canopy to discharge.
- Grease thickness is measured and the price is fixed before work starts.
- The kitchen is closed, the equipment cooled and everything nearby protected.
- We work through the system from the canopy to the fan and discharge.
- We re-test, photograph and send your certificate and photo report.
How to prepare
- Let us know about parking and loading
- Tell us the best time to work, such as after service or at a weekend
- Clear the space around the work

Getting a quote does not take long. Call or email with a few details and you will normally have a fixed price within one working day. If we need to see the system first, we book a survey around your hours.
Advice
Common questions in Knowle
Which environmental health team covers Knowle?
In Knowle, it’s Winchester City council that carries out food hygiene inspections. Ratings are published by the Food Standards Agency, so a clean extract and good records are worth keeping up.
Can you get to a site in Knowle?
Yes, smaller places are covered as well as towns. Let us know about access, parking and anything unusual about getting there when you book.
How much notice should we give?
That depends on the slot you want and the size of the job. Tell us your preferred dates when you ask for a quote, and for anything urgent, ring our 24/7 emergency line.
What do you do with what you remove?
We take it away when we go. During the work, it’s contained so the area stays clean.
Will the clean disrupt our service?
We work around your hours. Most kitchens book us overnight or at weekends and the kitchen is ready to cook when we leave.
How often does a kitchen extract system need cleaning?
Under BESA guidance, the minimum depends on how long you cook each day: every 3 months for 12 to 16 hours, 6 months for 6 to 12 hours and 12 months for 2 to 6 hours. Grease readings can show a shorter interval is needed.
Do insurers need proof of extract cleaning?
Grease-filled ducts can carry fire well beyond the kitchen. Many insurers require TR19 cleaning, and may refuse or reduce a claim without proof, so keep every certificate.
What paperwork comes with a kitchen extract clean?
You receive a TR19 certificate and a photo report. The certificate is issued through the BESCA Vent Hygiene Elite portal, and the report shows before and after photos, readings, any areas not reached and the next clean date.
Kitchen extract cleaning around Knowle
Food Standards Agency data counts about 9 restaurants, cafés and works canteens within about 1.5 miles of central Knowle. Each one that cooks under a canopy has an extract system that collects grease and needs regular cleaning. 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. It’s Winchester City council that sends environmental health officers to food businesses in Knowle. They look at how clean the premises and equipment are, and the kitchen extract is part of that. Keeping each certificate and photo report on file helps show the extract is looked after.
Where a hall near Church of St Francis, or anywhere in Knowle, hosts lunch clubs or events, its extract gathers grease just as a café’s does. If you run catering at a healthcare site, such as a hospital like Knowle Hospital about under half a mile north-east, the extract may need cleaning more often than a part-time kitchen.

Keeping the system healthy
How long the results last depends on use and care. We suggest:
- Keep the baffle filters clean
- Give the canopy a daily wipe
- Empty any grease troughs or cups on the canopy
- Keep the cleaning records where you can find them
You get a photo report after every clean. Before and after pictures show each part of the system, alongside a list of what was cleaned, anything out of reach and the recommended next clean date.
Clean the grease filters often, not just on clean day. A filter that is clean and seated properly stops more grease getting into the plenum, so the ductwork stays cleaner for longer.
Why deal with it now?
Leaving the clean until the next refit does not make the grease go away. Fat that was soft and easy to remove hardens with heat and time, which is slower to clean. Regular cleans keep each visit shorter. Planning a trip to Knowle ahead is easier for everyone than a rushed one.
You won’t find a price list here, because each job is priced on what it involves. Call for a fixed quote, and we will talk you through it.

In-house cleaning or a specialist?
In-house cleaning and specialist cleaning do different jobs. A daily filter wipe and a weekly filter wash keep grease down at the front of the system, but grease that has passed the filters is out of reach. That part needs specialist access and equipment.
Day-to-day cleaning is something your team can do: wiping down canopy surfaces, cleaning filters and keeping a simple log. Inside the ducts, risers and fan is specialist work, and that is where we come in.
