Grease filter exchange in Knapp, done properly
Grease filters are the first line of defence in a kitchen extract. They catch grease before it reaches the plenum and ductwork and they do it best when they’re clean. With grease filter exchange, clean filters replace greasy ones at regular intervals. We are often asked to deal with filters that leave gaps in the canopy and missing filters in the filter bank, on wall canopies, baffle filters and island canopies.
Rural kitchens often have long, low duct runs through a roof space or along an outside wall, and those horizontal sections are where grease settles. Access, parking and timings are agreed before the day.
We’ve been trading since 2009, and we’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we carry full insurance.

What we do, step by step
We start by comparing what we find with the survey or your photos. If anything is different, we talk it through with the person on site before carrying on. From there, it takes less than an hour in most kitchens. Photos of the system and how to reach it help us plan a visit to Knapp.
- The filters in each canopy are measured and counted.
- An exchange schedule is agreed to suit your cooking.
- On each visit, we remove the greasy filters.
- Clean filters go in and we check they sit snugly.
- The dirty filters leave with us and the next visit is booked.
Getting ready for the visit
- Plan for cooking equipment or plant to be off before we arrive
- Tell us about site rules, permits or sign-in
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
Ask for a quote
We do not publish a price list, because every site is different. We look at your system first, from photos or on a visit, then send a fixed quote. To start, give us a ring on 0345 646 2711, or send details by email.

Grease filter exchange around Knapp
The FSA’s data shows about 5 bars, pubs and nightclubs registered within 1.5 miles or so of the middle of Knapp. A pub or hotel kitchen that cooks every day builds up grease in its extract like any other. It’s Test Valley council that sends environmental health officers to food businesses in Knapp. A greasy canopy or dripping filters are the sort of thing an inspection can pick up. Our report lists what was cleaned and when, which is useful to have ready. Hampshire and Isle of Wight Fire and Rescue Service covers Knapp. Its fire safety officers can audit commercial kitchens, and grease in the extract is part of a kitchen’s fire risk.
If you run catering at a healthcare site, such as a hospital like Romsey Community Hospital about 2.9 miles south-west, the extract may need cleaning more often than a part-time kitchen. Church and community hall kitchens, near Church of St Mark or anywhere around Knapp, are easy to forget, but their extracts collect grease like any other.

Questions from Knapp
Do you clean school canteen extracts around Knapp out of term?
Yes, and it’s the easiest time to do it. There are about 2 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of Knapp. Tell us your holiday dates and we’ll book the visit for when the site is empty.
Which environmental health team covers Knapp?
That’s Test Valley council, whose environmental health officers carry out food hygiene inspections in Knapp. Ratings are published by the Food Standards Agency, so a clean extract and good records are worth keeping up.
What if parts of the system can’t be reached?
We never leave them off the paperwork. You will know exactly which parts weren’t reached and why, and we can quote to improve the access.
Do you look at the system first?
Yes, every time. Diagnosis comes before treatment: the survey shows what needs doing and what access we need, and the quote is based on that.
Can you set up regular visits?
Yes. Plans on a 3, 6 or 12-monthly cycle are available, depending on what the system needs.
Can one contract cover all our sites?
Yes. You deal with one contact for every site across London and the South East, and visits can be set on a regular cycle.
Will we have to stop cooking for a filter change?
Visits are short, and can be booked outside service times. There’s no wait between removing and refitting.
What is 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.
Fixed quotes for grease filter exchange in Knapp
Some jobs are bigger than they look, and some smaller. The main factors:
- The number of sites or systems

What to send for a quote
Photos let us diagnose from a distance. The most useful are:

- Where the plant sits or the system leaves the building, such as a roof or outside wall

What else we do in Knapp
When to call us in Knapp
The type of cooking matters. Frying, grilling and chargrilling produce far more grease than steaming or baking so no single schedule suits every kitchen.
Any of these means the system needs a check-up:
- Grease dripping from the canopy
- Filters that come out of the sink still dirty
- Grease filters clogged with grease
- Filter washing that keeps being missed
For schools such as Ampfield Church of England Primary School, kitchen extract cleaning is typically booked for the holidays, when the canteen is closed.
Before you book anyone
- Which accreditations they hold, and whether you can check them
- When the next visit should be, and why
- If the quote is a fixed price or an estimate
- Whether the quote shows VAT
What the work involves, part by part
Baffle filters
Baffle filters are a common choice for commercial canopies. They do not clean themselves as the collected grease builds up between the blades.
Busy restaurant and pub kitchens
The more a kitchen cooks, the more grease the filters see. Regular changes help protect the ductwork.
In-house cleaning or a specialist?
For ventilation and air handling systems, in-house care is mostly about checks: clear grilles, a log of filter changes and reporting anything odd. Cleaning inside ducts and units is specialist work.
A few tasks are always specialist work: entering ducts, working on fans, testing dampers and taking grease readings call for the right kit, training and safe access. Leave those to us.
