About our grease filter exchange in The City
The filters in the canopy are the first thing cooking vapour meets. They catch grease before it reaches the plenum and ductwork, but only while they’re reasonably clean. With grease filter exchange, clean filters replace greasy ones at regular intervals. The work covers island canopies, school and hospital kitchens and wall canopies, and the jobs we see most are blocked baffle filters and smoke and heat lingering under the hood.
Somewhere as small as The City, commercial kitchens are few: perhaps a pub, a school or care home kitchen, or a hall used for events. Every one of them still needs its extract kept clear of grease.
For insurers and inspectors, the record counts. So every job comes with a written report and pictures, and grease extract cleans come with a TR19® certificate issued through the BESCA Vent Hygiene Elite portal.

What we’re called out for in The City
Cooking vapour carries grease into the canopy. The filters catch much of it, and day by day they load up until the air can barely get through.
Most sites get in touch when they notice something like this:
- Filters left unwashed on busy weeks
- Blocked baffle filters
- Grease left in baffles after washing
- Damaged filters letting grease past
If you run catering at a historic house or estate in the area (West Wycombe Park House is about 2.7 miles south-east), event kitchens in older buildings often have awkward duct runs that need planning.
What to look for in a quote
- Whether the quote shows VAT
- What’s included in the scope, part by part
- Their accreditations, such as BESCA Vent Hygiene Elite, CHAS or SafeContractor
- How they set the interval to the next visit
What happens if it’s left?
Leaving filters too long pushes more grease into the plenum and ducts. That makes the next full clean a bigger job and grease readings can rise between cleans. Systems in rural buildings are often out of sight and out of mind.
What you pay reflects the actual work. That is why we survey first, from photos or on site, and why the quote is fixed before work begins.
What you get with us
- Photo reports with every job
- Accredited under CHAS and SafeContractor, with ISO 9001
- Member of BESCA Vent Hygiene Elite, cleaning to BESA TR19® Grease
- We are fully insured
Keeping the system healthy
Good habits slow the build-up between visits. A few tips:
- Book full TR19 cleans alongside filter changes
- Tell us if the menu or opening hours change
- Report a dripping canopy early
- Keep canopy surfaces wiped down
Once the clean filters are in, the kitchen can cook right away. The dirty set leaves with us to be cleaned.
A kitchen that’s getting busier needs its filters changed more often. Adjusting the schedule now prevents a build-up in the ducts.

What happens on the day
We are used to working while the site is closed. Evenings, nights and weekends are when much of our work happens, so the site can open as normal afterwards.

- We look at the canopies and the condition of the filters.
- We note any filters that are bent, damaged or missing.
- We exchange the dirty filters for a clean set.
- The filters are checked for fit before we go.
- We tell you if the plenum or canopy needs a clean.

Grease filter exchange in The City: the local picture
Food Standards Agency records list about 4 cafés, restaurants and staff canteens within 1.5 miles or so of the middle of The City. Swapping filters on a schedule keeps kitchens like these drawing air properly. Food hygiene inspections in The City are the job of Buckinghamshire council’s environmental health team. A greasy canopy or dripping filters are the sort of thing an inspection can pick up. A dated certificate in the maintenance file answers the question before it’s asked. The City is covered by Buckinghamshire Fire and Rescue Service. The Fire Safety Order puts the duty on whoever runs a kitchen to control its fire risk, and a greasy duct is fuel.
If you look after a school kitchen, at a school such as Radnage Church of England Primary School or anywhere near The City, the holidays are the usual time for a TR19® clean. Healthcare kitchens, like those at hospitals such as Wycombe Hospital (about 5 miles south-east), often cook for long hours, which puts them in BESA’s heavier-use bands.

What staff can safely do
For ventilation and air handling systems, in-house care is mostly about checks: clear grilles, a log of filter changes and reporting anything odd. The inside of ducts and units needs a specialist.
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.
