Grease filter exchange in Stonor
Across Stonor, our filter exchange suits restaurants, pubs, cafés, schools, care homes and other kitchens, whether there’s one canopy or many. We can come before or after service so nobody has to stop cooking. The work covers wall canopies, school and hospital kitchens and island canopies, and people most often call us about grease dripping from the canopy and a canopy running with filters missing.
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.
For insurers and inspectors, the record counts. So every job comes with a written report and pictures, plus a TR19® certificate through the BESCA VHE portal where the work is a TR19® Grease clean.

For landlords and multi-site operators
Running several sites is easier with one contractor. We work across London and the South East, so visits at different addresses can be planned together 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 pictures, so records stay tidy.
When it’s something else
We’d rather tell you now than book work that won’t help, so here are the limits:
- A noisy or failed extract fan
- Smell complaints that need odour control equipment
- A canopy too small for the cooking beneath it
If you’re not sure, just phone us on 0345 646 2711 or drop us a line and we will give you a straight answer before booking.
What we work on in Stonor
- Island canopies
- School and hospital kitchens
- Baffle filters
- Wall canopies
- Restaurants and pubs
- Mesh filters
Between visits
Aftercare is simple, and it makes the next visit easier:
- Keep the extract on whenever the range is in use
- Make sure we can reach the canopy on exchange day
- Do not let the full clean slip because filters are changed
- Clean the canopy surfaces regularly
We tell you if we spot anything in the canopy that needs attention. It can be a sign that a full TR19® clean is due and we can book that in.
Saturated filters let more grease through. Getting onto a regular exchange now keeps grease out of the plenum and ductwork between full cleans.
Part by part
Busy restaurant and pub kitchens
The more a kitchen cooks, the more grease the filters see. Regular changes help protect the ductwork.
Baffle filters
When baffles fill with grease, less air gets through. A clean exchange set brings the airflow back.
How we price grease filter exchange
We quote each job individually. These are the things that affect it:
- Site rules, permits and inductions
- Whether we need access equipment or extra panels
- How many systems or sites are involved
- Travel, parking and unloading
What you pay reflects the actual work. That is why every job is surveyed first, and why the quote is fixed before any work starts.
Asking for a quote
Many jobs can be priced from pictures and some basics. Useful things to send:
- Your last certificate, test record or report
- Problems your staff have spotted
- How we’d reach plant on a roof or in a plant room
- Close-ups of filters, grilles, hatches or access panels
Here’s what helps us quote: where the site is, what it is and its opening hours, photos of the system and the last certificate or report, if there is one. Once you have those, call us on 0345 646 2711 or send us an email.
What happens on the day
At the end of the visit, someone from your team can look over the work with us. Anything we couldn’t reach or that needs attention is pointed out there and then, and the same goes into the written report. All told, the work takes well under an hour for most canopies. Somewhere as small as Stonor, the date and timings are agreed with you well before the day.
- We record the number, size and type of your filters.
- We set the interval with you.
- 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.
Before we arrive
- Let us know about parking and loading
- Move anything stored near the system
- Tell us the best time to work, such as after service or at a weekend

Why it’s worth doing now in Stonor
When filters block, extraction suffers. The kitchen gets hotter and smokier while the fan strains. A regular exchange keeps the airflow where it should be. Rural sites can’t always move to another kitchen or room when something fails.
Combining work into one visit or one programme often makes better use of the time. Mention every system or site you need covered, and you will get one fixed quote.

- Every visit written up, with pictures

Grease filter exchange around Stonor
Food hygiene inspections in Stonor are the job of Buckinghamshire council’s environmental health team. An officer looking round a kitchen will see the canopy, and grease there is hard to miss. A TR19® certificate and photo report after each clean gives you a record to show an inspector. About 37 miles out from central London, Stonor is part of the South East area we work across. We work evenings, overnight and at weekends, so the visit fits around the site.
Where a hall near Pishill Church, or anywhere in Stonor, hosts lunch clubs or events, its extract gathers grease just as a café’s does. Older buildings often hide long, awkward duct runs, and if you run a kitchen at a historic venue in the area (Stonor Park is about 0.5 miles south-east), access may need planning.

Questions from Stonor
Can the work in Stonor be done at night or at weekends?
Yes, we can come after you close and finish before you open. It means the site in Stonor keeps running as normal. Tell us your opening hours when you ask for a quote.
Which environmental health team covers Stonor?
Food hygiene inspections in Stonor are carried out by Buckinghamshire council. An officer may look up into the canopy, so clean filters on the day and a recent certificate on file both help.
Does the report say when we need you again?
Yes. We put a recommended next date on the report. BESA’s minimum intervals for kitchen extracts range from 3-monthly for heavy use to 12-monthly for light use, while fire dampers are tested at least annually.
Can you come out in an emergency?
Yes. For anything urgent, such as a fan failure or damage after a fire, ring the 24/7 line and we’ll talk you through the next steps.
Do you take the used filters away?
Yes. The dirty filters are taken away for cleaning while a clean set goes in.
What if some of our filters are damaged?
A badly damaged filter should be replaced. We will tell you which ones and why on the visit.
Do you work with multi-site operators?
Yes. Tell us the addresses and what each needs and we will quote them together.
Can we skip TR19 cleans if the filters are changed regularly?
No. Clean filters help keep grease down, but the ducts and plenum still need cleaning at the right interval.
