About our grease filter exchange in Bushey
Baffle filters and mesh filters both fill with grease. Clogged filters choke the airflow and the extract struggles. Regular exchange keeps the air moving. If you have staff short of time to wash filters and grease filters clogged with grease, we can put it right.
Many kitchens in a town like Bushey were fitted into buildings built for something else, which can mean awkward duct routes, long flat runs and not enough access panels. Where the duct can’t be reached, new panels can be fitted, and anything left uncleaned is recorded on the report.
A written report with pictures follows each visit, so there’s a dated record of the work. Where the work is a TR19® Grease clean, the certificate is issued through the BESCA Vent Hygiene Elite portal.

What we do, step by step
Your staff don’t need to do much on the day. Someone lets us in at the agreed time and shows us where everything is, and the rest is down to us. Afterwards, the area is left tidy and the written report follows. Let us know how to reach the roof or plant area at your site in Bushey, and where the van can go.
- First, we check the canopies and the filters in them.
- We note any filters that are bent, damaged or missing.
- Greasy filters are swapped for clean ones.
- The filters are checked for fit before we go.
- We tell you if the plenum or canopy needs a clean.
How to prepare
- Dig out any earlier paperwork for the system
- Mention any locked doors, roof access or ceiling voids
- Name a contact who can let us in at the agreed time

Do you clean school canteen extracts around Bushey out of term?

Do you have a 24/7 line?

Is Bushey in your area?
Yes. Our area takes in London and the counties of South East England, and that includes Bushey.
Can we skip TR19 cleans if the filters are changed regularly?
No, the two work together. TR19® cleaning covers the canopy, plenum, ductwork and fan, with a certificate and photo report.
Is there a cleaning option for the filters we have?
Yes, filter cleaning is available. The first step is looking at the filters you have, as damaged ones may be better replaced.
How long does the visit take?
We will confirm the time with your quote. In most cases, the work takes anything from a few minutes to an hour or so, depending on the number of filters.
Different parts, different methods
Mesh filters
Mesh traps grease between its layers, which makes hand-washing hard work.
Canopy filter housings
We check that filters sit snugly in the housing at each visit since a gap is a route for grease.

Look up Bushey on the FSA’s food hygiene register and you will find about 43 restaurants, cafés and works canteens and about 10 takeaways within 1.5 miles or so of the middle of Bushey. Where they cook under a canopy, the grease filters are the first line of defence and clog quickly. Bushey sits within the area of Hertfordshire Fire and Rescue Service. In most workplaces, including commercial kitchens, it’s the fire and rescue authority that enforces the Fire Safety Order. In Bushey, food businesses are inspected by environmental health officers from Hertsmere council. Extraction counts as kitchen equipment, so its condition can come up on the day. Our report lists what was cleaned and when, which is useful to have ready.
Kitchens that cook twelve hours or more a day, as some healthcare kitchens do, fall into BESA’s three-monthly minimum; Watford General Hospital is the nearest hospital to Bushey, about 2.1 miles west. If your kitchen is in a listed or historic building, like the houses around Bushey (Headstone Manor is about 3.5 miles south), fitting access panels needs care.

What we are called out for in Bushey
Washing filters by hand does not always get them clean. Grease hides in the folds of a baffle or the layers of a mesh and a sink wash rarely reaches it.
Common reasons sites call us include:
- Missing filters in the filter bank
- Grease filters clogged with grease
- Weak extraction at the canopy
- A greasy plenum behind the filters
Term dates shape school work: for a school like Little Reddings Primary School, an extract clean fits neatly into a half-term or summer break.

Looking after it afterwards
Good habits slow the build-up between visits. A few tips:
- Never leave gaps in the filter bank
- Wipe the outside of the canopy as part of daily cleaning
- Book full TR19 cleans alongside filter changes
- Report a dripping canopy early
The next exchange is already in the diary. If cooking increases, we can change filters more often to match.
Dripping filters are a clear sign they’re full. Changing them now reduces the fuel above the cooking and the plenum may need a clean as well.
For landlords and multi-site operators
Facilities teams in offices, schools and healthcare sites book us too in Bushey and across Hertfordshire. Work can be phased by floor, building or site to keep disruption down.
Landlords, managing agents and facilities managers book us, not only the businesses that use the systems. Shared systems, like a riser serving several units, need a clear agreement on who books the work, and we are happy to quote for all of it.
What staff can safely do
Away from the kitchen, the in-house job is mainly checking: clear grilles, a log of filter changes and reporting anything odd. Cleaning inside ducts and units is specialist work.
When your team notices a problem between visits, such as dripping grease, a noisy fan, a smell or a filter that won’t come clean, they should report it rather than try to fix it. We can diagnose it and quote.
