Grease Filter Exchange in Henley-on-Thames
We cover Henley-on-Thames for a scheduled grease filter exchange, swapping dirty canopy filters for clean ones. Out-of-hours visits, a fixed quote and a written report with photos as standard.

- Filters left unwashed on busy weeks
- Grease building up behind the canopy filters
When it’s something else
We’d rather tell you now than book work that will not help, so here are the limits:
- An extract that was undersized from the start
- Smell complaints that need odour control equipment
- Grease behind the filters that a swap cannot remove

Grease filter exchange for kitchens and businesses in Henley-on-Thames
We set up grease filter exchange for kitchens in Henley-on-Thames on a schedule that suits their cooking. Busy kitchens need changes more often while a lighter kitchen can go longer. We agree the interval with you at the start. The work covers wall canopies, restaurants and pubs and school and hospital kitchens, and common reasons people get in touch are a greasy plenum behind the filters and grease left in baffles after washing.
In a smaller place like Henley-on-Thames, the kitchens with extract systems are more likely to be a pub, a café, a takeaway or a school or care home kitchen than a big restaurant. Quieter kitchens still collect grease in the duct, just more slowly, so the interval is set by hours of use and grease readings.
The paperwork matters as much as the work. You get a written report with pictures after each visit, covering the work done, any areas we couldn’t access and a recommended next date. File it in your maintenance log so it’s to hand when an insurer or inspector asks.

What we are called out for in Henley-on-Thames
Repeated removal and washing takes its toll on filters. A bent filter doesn’t seat properly, leaving gaps for grease to slip through.
It’s time to book a visit if you see:
- Gaps where filters have been removed
- A canopy that drips grease
- Poor airflow through the filters
- Blocked baffle filters
Commuter trade near Henley-On-Thames station can mean long cooking hours, and long hours put a kitchen into BESA’s more frequent cleaning bands.
What your quote should include
- If they look at the system before pricing
- Whether the figure could change on the day
- How they set the interval to the next visit
- Whether the work can be done while the site is closed
Why deal with it now?
Clogged filters choke the extract. The kitchen gets hotter and smokier while the fan strains. A regular exchange keeps the airflow where it should be. In a smaller place like Henley-on-Thames, a site that has to close is felt quickly.
Leaving it longer rarely makes the work cheaper. Problems in a system tend to grow, which can make the next visit longer. If you are unsure, call 0345 646 2711, or send details by email and we will give you an honest view and a fixed quote.

Staff cleaning versus specialist work
If your staff spot something between visits, like drips, unusual noise, smells or damaged filters, they should report it rather than try to fix it. We will take a look and send you a fixed quote.
A few tasks are always specialist work: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease need training, the right equipment and safe access. That’s our job.
Grease, kitchens and Henley-on-Thames
The FSA’s food hygiene register includes about 17 pubs and bars within about 1.5 miles of central Henley-on-Thames. A pub or hotel kitchen that cooks every day builds up grease in its extract like any other. Kitchens in Henley-on-Thames get their food hygiene inspections from South Oxfordshire council. An officer looking round a kitchen will see the canopy, and grease there is hard to miss. Before-and-after pictures from each clean are a simple way to show the extract is in hand. Fire safety in Henley-on-Thames falls to Oxfordshire Fire and Rescue Service. Its fire safety officers can audit commercial kitchens, and grease in the extract is part of a kitchen’s fire risk.
Where a hall near Holy Trinity Church, or anywhere in Henley-on-Thames, hosts lunch clubs or events, its extract gathers grease just as a café’s does. School kitchens, at schools like Trinity Church of England Primary School for example, are usually cleaned in the holidays so no lunches are lost.

Aftercare tips
So the system stays in good health:
- Book full TR19 cleans alongside filter changes
- Wipe the outside of the canopy as part of daily cleaning
- Report damaged filters so they can be replaced
- Never cook with the extract switched off
Keep an eye out for filters that have been taken out. Gaps let grease into the plenum so tell us if you need a replacement.
Bent or missing filters let grease straight past. Sorting them now keeps grease where it can be caught.
Different parts, different methods
Mesh filters
Mesh filters use layers of metal mesh to trap grease. In a busy kitchen, mesh soon blocks and need frequent attention.
Canopy filter housings
Grease collects in the channels and drip trays below the filters. We point it out if it needs cleaning.
What happens on the day
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. After that, the work takes a few minutes per canopy, longer for a large kitchen with several canopies. We plan the journey to Henley-on-Thames and bring what the job is likely to need.
- We record the number, size and type of your filters.
- An exchange schedule is agreed to suit your cooking.
- On each visit, we remove the greasy filters.
- A clean set is fitted and checked for gaps.
- We take the greasy set away and confirm the next date.
Getting ready for the visit
- Tell us the best time to work, such as after service or at a weekend
- Tell us about site rules, permits or sign-in
- Allow time for equipment near the work to be turned off and cool down
Get a fixed quote
Some systems can be priced from photos; others need a survey. Larger sites, and anything hidden behind walls, ceilings or floors, are normally surveyed first. Either way, the quote is fixed before any work is booked.
