Why deal with it now?
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. A small fault found now is a quick job; the same fault found later can close the site.
When the work has to happen, how we reach it and how big the site is all affect the cost. Each of those is built into the quote, and the price is fixed before work begins.
Why us?
- One number for every site across the South East and London

Grease filter exchange in Gravesend
The filters in the canopy are the first thing cooking vapour meets. They catch grease before it reaches the plenum and ductwork, but only while they’re reasonably clean. Our grease filter exchange service swaps dirty filters for clean ones on a schedule. Typical jobs include missing filters in the filter bank and damaged filters letting grease past, across baffle filters, mesh filters and wall canopies.
Many kitchens in a town like Gravesend 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.
It’s worth checking any contractor’s accreditations. We are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we hold CHAS, SafeContractor and ISO 9001, and we are fully insured.

FAQs for Gravesend
Is grease filter exchange any different in a coastal place like Gravesend?
It can. Gravesend is within about 2 miles of the coast, and salt air speeds up corrosion. Rooftop fans, discharge cowls and fixings are checked for corrosion as well as grease.
Can you clean school kitchen extracts in Gravesend during the holidays?
Yes, out-of-term visits are normal for schools. The FSA’s register shows about 33 schools and colleges with food registrations within roughly a mile and a half of Gravesend. Tell us your holiday dates and we’ll book the visit for when the site is empty.
Do you have a 24/7 line?
Yes, day and night, every day of the year. Office hours are Monday to Friday, 8am to 6pm, and the emergency line covers the rest.
What’s the right interval for changing filters?
It varies with the type and amount of cooking. If filters clog early, the interval needs shortening and we’ll adjust it.
How much does a filter exchange service cost?
Filters, canopies and how often you need visits all affect the price. Send us details or pictures and we’ll quote quickly.
Can you clean our existing filters instead?
Yes, filters can be cleaned on a schedule as well as exchanged. We’ll talk you through which suits your kitchen when we quote.
Do you recommend a next date?
Yes. We put a recommended next date on the report. BESA’s minimum intervals for kitchen extracts range from 3-monthly for heavy use to 12-monthly for light use, while fire dampers are tested at least annually.
Is filter exchange enough instead of a full extract clean?
No. Filters do not catch everything, so grease still reaches the ductwork and the whole system still needs its TR19 clean.
What we do, step by step
We turn up 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 before we start, and the area around the work is covered and protected. On site, it takes less than an hour in most kitchens. In Gravesend, the visit is planned around your opening hours, parking and access to the system.
- First, we record the size, type and number of filters in each canopy.
- Together we set how often the filters should be changed.
- At each visit, the greasy filters are lifted out.
- We fit clean filters and check they sit snugly in the housing.
- We flag any damaged filters or anything wrong with the canopy.
Preparing for the visit
- Move anything stored near the system
- Let us know when the site is closed or quiet
- Let us know how we reach the system, including roofs, risers and plant rooms

Quoting starts with a diagnosis, from your photos and details or, where that is not enough, a survey on site. After that, you get a fixed price for the work, before any work starts.
Advice
Looking after it afterwards
Think of this as the after-treatment advice, short and simple:
- Book full TR19 cleans alongside filter changes
- Keep every filter in place during service
- Keep canopy surfaces wiped down
- Clear anything stored on or near the canopy
Your next visit is scheduled before we leave. If cooking increases, we can change filters more often to match.
If filters are already dripping, they’re overdue. Changing them now reduces the fuel above the cooking, and it’s worth checking the plenum too.
Part by part
The plenum
Behind the filters sits the plenum, where air gathers before the duct. Grease that gets past the filters settles there.
Mesh filters
Grease lodges deep in the layers of a mesh filter, so a quick rinse rarely gets it clean.
Grease filter exchange in Gravesend: the local picture
Gravesend lies within about 2 miles of the sea. Salt in the air is hard on rooftop fans, discharge cowls and fixings, so we check them for corrosion as well as grease. Look up Gravesend on the FSA’s food hygiene register and you will find about 106 cafés, restaurants and staff canteens and about 73 takeaways and sandwich shops within roughly a mile and a half of the centre of Gravesend. Each canopy among them has filters that load with grease and need swapping or cleaning. It’s Gravesham council that sends environmental health officers to food businesses in Gravesend. 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.
Commuter trade near Gravesend station can mean long cooking hours, and long hours put a kitchen into BESA’s more frequent cleaning bands. Bursars and site managers at schools such as Whitehill Primary School tend to book extract cleaning for when the kitchen is empty.

Do you need grease filter exchange in Gravesend?
Missing filters are more common than you’d think. A missing filter leaves an open route into the system and on into the ductwork.
Look out for any of the following:
- Grease left in baffles after washing
- Grease dripping from the canopy
- Staff short of time to wash filters
- Grease building up behind the canopy filters
If you run a church or community hall kitchen, near Christ Church Milton or elsewhere in Gravesend, its extract still collects grease from every lunch and event.
