Grease filter exchange in Charlton, Greater London
Professional grease filter exchange in and around Charlton, timed so the site keeps working and finished with a written report and photos.

Grease filter exchange in Charlton
Baffle filters and mesh filters both fill with grease. Clogged filters choke the airflow and the extract struggles. Regular exchange keeps the air moving. The work covers baffle filters, island canopies and school and hospital kitchens, and common reasons people get in touch are blocked baffle filters and poor airflow through the filters.
In London, few kitchens can spare a day to close, so extract cleaning in Charlton is typically done overnight, after the last service. Before the clean, we agree loading, parking and roof access with whoever manages the building.
We have been trading since 2009, and we are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we’re fully insured.

Common problems we fix in Charlton
Repeated removal and washing takes its toll on filters. A bent filter doesn’t seat properly, leaving gaps for grease to slip through.
Keep an eye out for any of the following:
- Drips falling from the filters onto equipment
- Staff short of time to wash filters
- Filters so greasy the air can barely pass
- Grease left in baffles after washing
If you run catering at a healthcare site, such as a hospital like British Hospital for Mothers and Babies about 0.5 miles east, the extract may need cleaning more often than a part-time kitchen.

Why act early in Charlton
Filters full of grease are fuel sitting right above the cooking. Flames from the range can be drawn up into the canopy, and from there into the duct. Keeping filters clean takes some of that fuel away. A booked night’s work in Charlton costs you no trading time; an unplanned closure does.
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 will explain each part.

What happens on the day
On the day, we arrive at the time agreed with you, often in the evening, overnight or at the weekend so the site keeps working. Anything that needs to be off for the work is switched off and left to cool before any work starts, and floors and nearby surfaces are sheeted. On site, it takes anything from a few minutes to an hour or so, depending on the number of filters. For a job in Charlton, tell us about loading bays, permits, lifts and roof access when you book.
- We count and measure the filters in every canopy.
- A change schedule is agreed to match the kitchen’s cooking hours.
- Each visit starts with the used filters being removed.
- Clean filters go straight back in, seated properly with no gaps.
- We flag any damaged filters or anything wrong with the canopy.
Getting ready for the visit
- Let us know how we reach the system, including roofs, risers and plant rooms
- Clear loose items from the work area
- Tell us the best time to work, such as after service or at a weekend

Advice
When something else is needed
We will not sell you work that doesn’t address the problem, so here are the limits:
- A heavily greased plenum or canopy, which needs cleaning to TR19
- A canopy that does not capture the vapour properly
- A noisy or failed extract fan
If you’re not sure, just give us a ring on 0345 646 2711, or send details by email and we will give you a straight answer.

Managing agents and facilities teams in Charlton
Landlords, managing agents and facilities managers book us, not only the businesses that use the systems. Shared systems, like a riser serving several units, need a clear agreement on who books the work, and we’re happy to quote for all of it.
We also work for facilities teams across offices, schools and healthcare across Greater London. Larger estates can be phased building by building around the people who use them.
How the job changes from site to site
Busy restaurant and pub kitchens
When service is non-stop, filters get forgotten. A regular exchange means nobody has to remember.
Baffle filters
When baffles fill with grease, less air gets through. Swapping them for a clean set restores it.

Your questions about grease filter exchange in Charlton
Do you clean school canteen extracts around Charlton out of term?
Yes, out-of-term visits are normal for schools. There are about 41 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of Charlton. Tell us your holiday dates and we’ll book the visit for when the site is empty.
Can you work in Charlton outside opening hours?
Yes, nights and weekends are routine for us. The work in Charlton can fit around your hours. Just give us a ring on 0345 646 2711 or email us with your opening times and we will plan around them.
What about areas you can’t get to?
We never leave them off the paperwork. The report says which parts couldn’t be reached and why, along with a quote to put access in.
Which kinds of sites do you work on?
We work for restaurants, pubs, hotels, schools, colleges, hospitals, care homes, offices and shops, as well as food production and leisure sites.
Is TR19 cleaning required by law?
No. TR19® itself isn’t law; it’s a BESA specification. The law is the Regulatory Reform (Fire Safety) Order 2005, which makes the responsible person assess and reduce fire risk, and cleaning to TR19® is the recognised way to show grease is under control.
Can you clean our existing filters instead?
Yes. Some kitchens prefer their own filters cleaned on a schedule, and others prefer a straight swap. We make sure the canopy is ready for service either way.
How regularly do grease filters need exchanging?
The right interval depends on the kitchen. If filters clog early, the interval needs shortening, and we can change it.
Do you survey before quoting?
Yes, always. Diagnosis comes before treatment: the survey shows what needs doing and what access we need and the fixed quote is built on it.
Looking after it afterwards
A little care between visits keeps the system in better shape. We recommend:
- Wipe the outside of the canopy as part of daily cleaning
- Report a dripping canopy early
- Clear anything stored on or near the canopy
- Book full TR19 cleans alongside filter changes
Between visits, check that every filter is still in place. A missing filter leaves a gap for grease so tell us if you need a replacement.
If filters are already dripping, they’re overdue. A clean set straight away cuts the grease in the canopy, and it’s worth checking the plenum too.
Grease filter exchange in Charlton: the local picture
The FSA’s data shows about 29 pubs and bars and about 4 hotels and guest houses registered across Charlton and its immediate surroundings (about a mile and a half). Wherever they cook, the canopy, duct and fan collect grease just as a restaurant’s do. In London, kitchens are typically cleaned overnight, when the kitchen is closed and loading is easier. In Charlton, food businesses are inspected by environmental health officers from Greenwich council. An officer looking round a kitchen will see the canopy, and grease there is hard to miss. A TR19® certificate and photo report after each clean gives you a record to show an inspector.
For schools such as Thorntree Primary School, kitchen extract cleaning is normally booked for the holidays, when the canteen is closed. If you run a church or community hall kitchen, near St Catherine Labouré or elsewhere in Charlton, its extract still collects grease from every lunch and event.
