Grease filter exchange in Bendish
Think of filter exchange as routine care for the extract. Between full cleans, it keeps the airflow healthy, and it saves your staff a greasy job. The full TR19 clean then gives the system its clean bill of health. The work covers baffle filters, restaurants and pubs and school and hospital kitchens, and the jobs we see most are hand-washed filters that still look greasy and drips falling from the filters onto equipment.
For a kitchen in or near Bendish, the visit is planned around opening hours and the journey, and the clean itself is the same full TR19® job as in any town: canopy to discharge, then a TR19® certificate and a photo report.
Nothing is signed off by word of mouth: a written report, dated and illustrated with pictures, plus a certificate through the BESCA Vent Hygiene Elite portal when the work is a TR19® Grease clean. It shows what was done and what, if anything, couldn’t be reached.

What grease filter exchange cannot fix
Before booking, it helps to know what’s not included:
- Grease behind the filters that a swap cannot remove
- Grease already built up in the ductwork, which needs a full TR19 clean
- Odours from the discharge that filters will not stop
Not sure which it is? You can give us a ring on 0345 646 2711, or email photos and we’ll tell you honestly.
Parts of the system we cover
- Mesh filters
- Baffle filters
- Island canopies
- Restaurants and pubs
- Wall canopies
- School and hospital kitchens
Between visits
Here’s the after-treatment advice, in brief:
- Tell us if a filter is bent or damaged
- Clear anything stored on or near the canopy
- Look out for drips from the canopy
- Make sure no filter is left out
We tell you if we spot anything in the canopy that needs attention. That might mean bringing a TR19® clean forward, and we can arrange it.
Filters that are left too long stop protecting the system. Getting onto a regular exchange now keeps grease out of the plenum and ductwork until the next TR19 clean.
For landlords and multi-site operators
We regularly work with managing agents. Tell us the site, the work and the access arrangements, and we’ll send a fixed quote.
Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person must assess and reduce fire risk, and that can be the employer, the owner, a landlord, a facilities manager or a managing agent. With shared responsibility, good records help everyone.
Bendish questions
Do you clean school canteen extracts around Bendish out of term?
Yes, holiday work suits schools best. The FSA’s register shows about 2 schools and colleges with food registrations within roughly a mile and a half of Bendish. Tell us your holiday dates and we will book the visit for when the site is empty.
Can you work in Bendish outside opening hours?
Yes. We work evenings, overnight and at weekends. The work in Bendish can fit around your hours. Tell us your opening hours when you ask for a quote.
What’s the right interval for changing filters?
It varies with the type and amount of cooking. If filters are dripping or clogging before the next change, it’s too long and we’ll adjust it.
Which grease filters does the service cover?
The common types of grease filter: baffle and mesh. Mention how many canopies you have when you get in touch, or we’ll check on the first visit.
What paperwork should we keep on file?
Every certificate and report from each visit, kept together in your maintenance log, along with your own cleaning log. BESA says certificates should show the date, location and technician.
Do you survey before quoting?
Yes. For many sites, photos and a few details are enough, while bigger or harder-to-see systems are surveyed on site.
What if some of our filters are damaged?
Damaged filters do not seat properly and let grease through. We flag any we find so they can be replaced.
Can you clean our existing filters instead?
Yes. Some kitchens prefer their own filters cleaned on a schedule, and others prefer a straight swap. Either way, the canopy is not left without filters during service.

What we are called out for in Bendish
The type of cooking matters. Frying, grilling and chargrilling produce far more grease than steaming or baking, so the right exchange interval varies.
Most sites get in touch when they notice something like this:
- Grease dripping from the canopy
- Grease left in baffles after washing
- Bent or damaged filters that don’t sit properly
- A greasy plenum behind the filters
Historic houses near Bendish, such as Shaw's Corner about 3.7 miles south-east, are a reminder that older buildings with event kitchens can have long, awkward duct routes.

What we do, step by step

Visits to a village like Bendish are booked in advance, at a time that suits whoever runs the site.
- 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.
- We check the filters are seated and the canopy is ready to use.
- We tell you if the plenum or canopy needs a clean.
How to prepare
- Arrange a key holder or contact on site
- Tell us where we can park and unload
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas

What staff can safely do
Logging matters as much as cleaning. A simple log of filter washes, wipe-downs and checks shows an inspector that the system is looked after between visits, next to our reports.
Some jobs should never be done in-house: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease need training, the right equipment and safe access. Leave those to us.
Why act early in Bendish
Grease-loaded filters are a fire risk in their own right. A flare-up on the range can reach them and grease in the duct can carry a fire further. Clean filters mean less fuel in the canopy. It’s simpler to plan the work at Bendish now than to arrange it in a hurry later.
We do not list prices on the website, because the cost depends on the site in front of us. Call for a fixed quote, and we will talk you through it.
