About our grease filter exchange in Chartridge
We set up grease filter exchange for kitchens in Chartridge on a schedule that suits their cooking. The heavier the cooking, the more often filters need changing, lighter ones less. The interval is agreed before the first visit. Typical jobs include filter washing that keeps being missed and blocked baffle filters, on restaurants and pubs, baffle filters and mesh filters.
In a village or hamlet like Chartridge, the kitchens that need extract cleaning are normally 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. Each visit is written up with pictures, covering the work done, any areas we couldn’t access and a recommended next date. Keep it with your fire safety records so it’s to hand when an insurer or inspector asks.

What the work involves, part by part
School, care home and staff kitchens
For kitchens closed in the holidays, visits can be timed around term or rota so the filters are clean when cooking picks up.
The plenum
Heavy grease in the plenum often follows clogged or missing filters, or that a full clean is due.
In-house cleaning or a specialist?
When your team notices a problem between visits, like drips, unusual noise, smells or damaged filters, it’s best reported rather than tackled in-house. We can diagnose it and quote.
Staff cleaning and specialist work are not the same thing. A daily filter wipe and a weekly filter wash keep grease down at the front of the system, but grease that has passed the filters is out of reach. Reaching it takes a specialist with the right equipment.
Why act early in Chartridge
A filter exchange is a few minutes; a choked extract affects a whole service. It’s one of the simplest parts of looking after the system and few are as easy to forget. Systems in rural buildings are often out of sight and out of mind.
We do not list prices on the website, because each job is priced on what it involves. Call for a fixed quote, and we’ll talk you through it.

Kitchen extracts in Chartridge
It’s Buckinghamshire council that sends environmental health officers to food businesses in Chartridge. Extraction counts as kitchen equipment, so its condition can come up on the day. A TR19® certificate and photo report after each clean gives you a record to show an inspector. Fire safety in Chartridge falls to Buckinghamshire Fire and Rescue Service. Fire and rescue authorities enforce the Fire Safety Order in most non-domestic premises, and in a kitchen that fire risk includes the grease in the extract.
If you look after a school kitchen, at a school such as Chartridge Combined School or anywhere near Chartridge, the holidays are the usual time for a TR19® clean. Historic houses near Chartridge, such as Cholesbury Manor House about 2.1 miles north, are a reminder that older buildings with event kitchens can have long, awkward duct routes.

Chartridge questions
Which environmental health team covers Chartridge?
Kitchens in Chartridge are inspected by Buckinghamshire council’s environmental health officers. It helps to keep the extract cleaning records with your food safety paperwork, so they’re ready if asked for.
Can you get to a site in Chartridge?
Yes. Chartridge is within the area we cover across London and the South East. Just mention lanes, gates or anything else about the site when you book.
Do we need to close the kitchen while filters are changed?
Not for long, and we can time it to avoid service. Cooking shouldn’t happen with the filters out so the swap is done promptly.
Do I get a report after the visit?
Yes. It’s the record insurers and inspectors ask to see: a dated report with photos, listing the work and any areas we couldn’t reach.
Where does the waste go?
We contain it and take it with us. We collect grease, debris and waste water as we go rather than letting it spread.
Do you handle baffle and mesh filters?
Baffle filters and mesh filters. Mention how many canopies you have when you get in touch and we’ll confirm it on site.
What does TR19 mean?
TR19® is BESA’s specification for ventilation hygiene. Since 2019, TR19® Grease has been a standalone specification for grease in kitchen extract systems, and TR19® Air covers general supply and extract systems.
Do you recommend a next date?
Yes. The interval depends on how much the system is used and what we find and the report sets out why.
Looking after it afterwards
Looking after the system between visits is straightforward, and it helps at the next visit:
- Look out for drips from the canopy
- Let us know if your cooking hours increase
- Keep the canopy clear for exchange visits
- Tell us if a filter is bent or damaged
Your team carries on as normal, without the filter washing. Make sure we can reach the canopy on exchange day and tell us if service times change.
Clean filters plus regular full cleans keep the system in good health. Setting both up on a schedule means neither slips.
What grease filter exchange can’t fix
It’s worth knowing the limits before booking:
- Extraction problems caused by the fan rather than the filters
- Odours from the discharge that filters will not stop
- A canopy that does not capture the vapour properly
Not sure which it is? You can give us a ring on 0345 646 2711 or send us an email and we’ll tell you honestly before you book.
Where we work
- Restaurants and pubs

Common problems we fix in Chartridge
Missing filters are more common than you’d think. Every gap in the filter bank lets grease straight into the plenum and on into the ductwork.
Clients typically contact us after spotting one of these:
- Filters left unwashed on busy weeks
- Grease dripping from the canopy
- Smoke and heat lingering under the hood
- Grease filters clogged with grease
If you run catering at a healthcare site, such as a hospital like Chiltern Hospital about 3.1 miles south-west, the extract may need cleaning more often than a part-time kitchen.

- Whether the quote shows VAT
- Whether the figure could change on the day
- Which accreditations they hold, and whether you can check them
How the visit works
On the day, we arrive at the time agreed with you, which is often after service, overnight or at a weekend. Equipment that has to be off is switched off and allowed to cool first, and the area around the work is covered and protected. On site, it takes a few minutes per canopy, longer for a large kitchen with several canopies. Somewhere like Chartridge, lanes, gates and parking are worth mentioning in advance.
- The filters in each canopy are measured and counted.
- An exchange schedule is agreed to suit your cooking.
- On each visit, we remove the greasy filters.
- Clean filters go in and we check they sit snugly.
- The dirty filters leave with us and the next visit is booked.
Before we arrive
- Mention any sign-in, permit or induction we need
- Let us know about parking and loading
- Arrange a key holder or contact on site
