How we handle grease filter exchange in Denchworth
We set up grease filter exchange for kitchens in Denchworth on a schedule that suits their cooking. The heavier the cooking, the more often filters need changing, lighter ones less. We agree the interval with you at the start. If you have a greasy plenum behind the filters and bent or damaged filters that don’t sit properly, we can help.
In a village or hamlet like Denchworth, the kitchens that need extract cleaning are usually a pub, a school, a care home or a hall kitchen, wherever there is one. Every one of them still needs its extract kept clear of grease, whatever the size of the place.
The paperwork matters as much as the work. You get a written report with pictures after every 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.

Signs you need grease filter exchange in Denchworth
However long the kitchen cooks each day, the filters see every minute of it. Heavy daily use means fast build-up so changes need to come round sooner.
Any of these means the system needs a check-up:
- Grease left in baffles after washing
- Grease filters clogged with grease
- Damaged filters letting grease past
- A canopy running with filters missing
Where a hall near Church of St James, or anywhere in Denchworth, hosts lunch clubs or events, its extract gathers grease just as a café’s does.

What your team can do, and what needs us
Day-to-day cleaning is something your team can do: wiping down canopy surfaces, cleaning filters and keeping a simple log. What they can’t safely do is clean inside the ductwork, the fan or the risers, which is where we come in.
A few tasks are always specialist work: entering ducts, working on fans, testing dampers and taking grease readings call for the right kit, training and safe access. Leave those to us.
The process
The first job on site is protection: sheeting goes over floors and surfaces close to the work. Then we make the system safe and start. The work on site takes anything from a few minutes to an hour or so, depending on the number of filters, and we clear up before we go. For a village or hamlet like Denchworth, tell us about narrow lanes, gates and parking when you book.
- 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.
Before we arrive
- Make sure equipment near the work can be switched off and left to cool
- Name a contact who can let us in at the agreed time
- Move anything stored near the system

Advice
Between visits
How long the results last depends on use and care. We suggest:
- Report damaged filters so they can be replaced
- Keep the canopy clear for exchange visits
- Always run the extract while cooking
- Mention it if the kitchen gets busier
Your next visit is scheduled before we leave. If the kitchen gets busier, the interval can be shortened to match.
Clean filters plus regular full cleans keep the system in good health. Setting both up on a schedule keeps everything on track.
Questions from Denchworth
Is Denchworth within the area you cover?
Yes, we work in villages as well as towns, and Denchworth is covered. The journey is planned ahead, so a few details about the route help.
Which fire service covers Denchworth?
It’s Oxfordshire Fire and Rescue Service, which covers Denchworth. A recent cleaning certificate and a note of the next clean date show that grease in the extract is being managed.
Do you clean filters as well as exchanging them?
Yes, filters can be cleaned on a schedule as well as exchanged. We’ll explain the options when we quote.
What’s TR19?
TR19® is BESA’s specification for ventilation hygiene. Since 2019, TR19® Grease has been a standalone specification for grease in kitchen extract systems, while TR19® Air covers other supply and extract ductwork.
Will you tell us when the next visit is due?
Yes. How often depends on use and condition and the report sets out why.
Can you look after several sites?
Yes. Tell us the addresses and what each needs and we will quote them together.
Do you offer maintenance contracts?
Yes, of course. Send details of the systems and how they’re used, and we’ll suggest a schedule and quote for it.
How often should grease filters be changed?
There’s no single answer. The schedule is based on how heavily you cook and can change if your kitchen gets busier.
Kitchen extracts in Denchworth
The FSA’s food hygiene register shows about 3 cafés, restaurants and staff canteens and about 3 sandwich bars and takeaways within roughly a mile and a half of the centre of Denchworth. Swapping filters on a schedule keeps kitchens like these drawing air properly. Denchworth sits within the area of Oxfordshire Fire and Rescue Service. Grease in a kitchen extract is a recognised fire risk, and the fire authority enforces the law on managing it in most commercial premises. In Denchworth, food businesses are inspected by environmental health officers from Vale of White Horse council. They look at how clean the premises and equipment are, and the kitchen extract is part of that. A TR19® certificate and photo report after each clean gives you a record to show an inspector.
If you run catering at a historic house or estate in the area (Longworth House is about 4.7 miles north), event kitchens in older buildings often have awkward duct runs that need planning.

How the job changes from site to site
Busy restaurant and pub kitchens
When service is non-stop, filters get forgotten. An exchange service takes it off the rota.
Mesh filters
Layers of mesh catch grease droplets. In a busy kitchen, mesh soon blocks, so they need changing often.
Managing agents and facilities teams in Denchworth
The Fire Safety Order 2005 puts the duty to manage fire risk on the responsible person, and that can be the employer, the owner, a landlord, a facilities manager or a managing agent. With shared responsibility, good records help everyone.
We also work for facilities teams across offices, schools and healthcare across Oxfordshire. Larger estates can be phased building by building to keep disruption down.
Leave it or put it right?
Changing filters on schedule costs far less disruption than a blocked extract. It’s one of the simplest parts of looking after the system and few are as easy to forget. If the system at a site near Denchworth fails, there may be nowhere nearby to move to.
When the work has to happen, how we reach it and how big the site is can all change the price. We take each of them into account and give you a fixed price before work begins.
