Grease filter exchange for kitchens and businesses in Chesham
Cleaning filters by hand takes staff time and is easy to put off. With a filter exchange, we bring a clean set and take the dirty one away, so the canopy is never left without filters. We’re often asked to deal with grease building up behind the canopy filters and filters that come out of the sink still dirty, across baffle filters, restaurants and pubs and island canopies.
Many kitchens in a town like Chesham were fitted into buildings built for something else, which can mean awkward duct routes, long flat runs and not enough access panels. Sections we cannot reach are listed on the report, and access panels can be added.
Good records are part of the job. Each visit is written up with pictures, listing what was done, anything we couldn’t reach and when the next visit is due. File it in your maintenance log so it’s to hand when an insurer or inspector asks.

Signs you need grease filter exchange in Chesham
Wherever you are, Chesham included, filter washing is the job that gets skipped when the kitchen is busy. It only takes a couple of missed weeks for filters to fill with grease.
Keep an eye out for these warning signs:
- Grease filters clogged with grease
- Staff short of time to wash filters
- Bent or damaged filters that do not sit properly
- Gaps where filters have been removed
Healthcare kitchens cannot easily close, so their extracts are cleaned overnight or between meal services; the nearest hospital to Chesham is Amersham Hospital, about 3.4 miles south.
Questions to ask before booking
- Whether inaccessible sections are listed on the report
- How VAT is shown on the quote
- Exactly which parts of the system are covered
- What paperwork you get at the end
Chesham questions
Can a school canteen extract in Chesham be done out of term time?
Yes. Half-terms and the summer break are the natural time for school work. The FSA’s register shows about 11 schools and colleges with food registrations within roughly a mile and a half of Chesham. Booking early in the term gives the best choice of holiday dates.
Can the work in Chesham be done at night or at weekends?
Yes, nights and weekends are routine for us. The work in Chesham can fit around your hours. Let us know the hours you’re closed and we’ll book within them.
What types of premises do you cover?
Any site with a kitchen or a ventilation system to look after, from a small pub to a hospital. We work with hotels, schools, care homes, offices, retail and leisure sites.
What is TR19?
TR19® is the BESA specification for keeping ventilation systems clean. TR19® Grease, a standalone specification since 2019, covers grease in kitchen extract systems, while TR19® Air covers other supply and extract ductwork.
How long does grease filter exchange take?
That depends on the amount of work, but for many sites it takes anything from a few minutes to an hour or so, depending on the number of filters. We’ll give you a better idea when we quote.
Who has the legal duty for fire safety?
In the words of the Fire Safety Order 2005, it’s the responsible person. It’s normally the employer, or whoever controls the building, and in shared buildings more than one person can have duties. Your lease and fire risk assessment should make it clear.
Can we skip TR19 cleans if the filters are changed regularly?
It is not. Clean filters help keep grease down, but the ducts and plenum still need cleaning at an interval set by risk assessment.
Can we book visits on a schedule?
Yes. Tell us what you have and how it’s used, and we’ll suggest a schedule and quote for it.
Between visits
A little care between visits keeps the system in better shape. Our advice:
- Wipe the outside of the canopy as part of daily cleaning
- Tell us if the menu or opening hours change
- Report a dripping canopy early
- Make sure we can reach the canopy on exchange day
Keep an eye out for filters that have been taken out. A missing filter leaves a gap for grease so tell us if you need a replacement.
Dripping filters are a clear sign they’re full. Changing them now reduces the fuel above the cooking, and it’s worth checking the plenum too.
How we price grease filter exchange
The quote reflects the site in front of us. We take into account:
- What state the system is in
- Working hours and out-of-hours timing
- Access, including roofs, risers and ceiling voids
- The number of sites or systems
The price reflects the work, not guesswork. That is why we survey first, from photos or on site, and the price is agreed before any work starts.
Asking for a quote
When you contact us, it’s useful to have:
- How we’d reach plant on a roof or in a plant room
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
- When the site is open and when it’s quiet
- Any access panels or hatches you can see
Here’s what helps us quote: the address, the type of site and when it’s open, pictures of the system and any previous report or certificate. Once you have those, call us on 0345 646 2711, or send details by email.
Why it’s worth doing now in Chesham
When filters block, extraction suffers. Heat and fumes hang in the kitchen while the fan strains. A regular exchange keeps the airflow where it should be. A fresh certificate on file is the best thing to have when someone asks to see your records.
Whatever the type of site, the quote works the same way: the size of the job, access, condition and working hours. Call for a fixed quote and we’ll explain each part.
What you get with us
- Out-of-hours work and a 24/7 emergency line
- We diagnose before we treat
- A written report with photos after each visit
- We’re fully insured

For landlords and multi-site operators
When the building owner and the occupier are different, it’s worth checking the lease for who maintains the systems. We’re happy to deal with either side, and the report can go to both.
From a single site to a large estate, the standard is the same: a survey first, a fixed quote, the work timed around the site and a report with pictures.
What a clean will not put right
A few issues sit outside what this work can do:
- A canopy too small for the cooking beneath it
- A heavily greased plenum or canopy, which needs cleaning to TR19
- Grease already built up in the ductwork, which needs a full TR19 clean
If you’re not sure, just call us on 0345 646 2711 or email us and we will give you a straight answer.

Advice
Chesham kitchens: local notes
Food Standards Agency data counts about 24 restaurants, cafés and canteens and about 16 sandwich bars and takeaways in Chesham and the streets around it, up to about 1.5 miles out. Any of those kitchens with a canopy relies on its filters to catch grease before it reaches the duct. Chesham is covered by Buckinghamshire Fire and Rescue Service. The Fire Safety Order puts the duty on whoever runs a kitchen to control its fire risk, and a greasy duct is fuel. Food hygiene inspections in Chesham are the job of Buckinghamshire council’s environmental health team. An officer looking round a kitchen will see the canopy, and grease there is hard to miss. Keeping each certificate and photo report on file helps show the extract is looked after.
Bursars and site managers at schools such as Elmtree Infant and Nursery School tend to book extract cleaning for when the kitchen is empty. If your kitchen is in a listed or historic building, like the houses around Chesham (Cholesbury Manor House is about 3.5 miles north-west), fitting access panels needs care.
