Grease filter exchange in Thong
Whether your canopy has baffle or mesh filters, they load up with grease. Clogged filters choke the airflow and the fan has to work harder. A steady cycle of clean filters keeps extraction strong. If you are dealing with filters left unwashed on busy weeks and filters so greasy the air can barely pass, we can help.
In a village or hamlet like Thong, the kitchens that need extract cleaning are usually a pub, a school, a care home or a hall kitchen, wherever there is one. Each still has a canopy and duct that collect grease.
We’ve been trading since 2009, and we are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we carry full insurance.

Thong kitchens: local notes
Sea air reaches Thong, which sits within about 3 miles of the coast. Salt in the air is hard on rooftop fans, discharge cowls and fixings, so we check them for corrosion as well as grease. Food Standards Agency data counts about 12 cafés, restaurants and staff canteens and about 18 takeaways and sandwich shops within roughly a mile and a half of the centre of Thong. Each canopy among them has filters that load with grease and need swapping or cleaning. Thong is covered by Kent Fire and Rescue Service. Its fire safety officers can audit commercial kitchens, and grease in the extract is part of a kitchen’s fire risk.
Kitchens that cook twelve hours or more a day, as some healthcare kitchens do, fall into BESA’s three-monthly minimum; Gravesham Community Hospital is the nearest hospital to Thong, about 2.8 miles north-west. Term dates shape school work: for a school like Riverview Infant School, an extract clean fits neatly into a half-term or summer break.
Thong is about 2 miles south-east of Gravesend, in Kent. If you need grease filter exchange in Thong, it’s easy to get a fixed quote: please ring 0345 646 2711 or send us an email.

Staff cleaning versus specialist work
When your team notices a problem between visits, like drips, unusual noise, smells or damaged filters, they should report it rather than try to fix it. We will take a look and send you a fixed quote.
Logging matters as much as cleaning. A dated log of in-house cleaning and checks helps show that the system is managed between specialist visits, alongside our reports.
What affects the quote in Thong
The diagnosis comes before the price. We look at:
- Working hours and out-of-hours timing
- Whether several sites go on one quote
- The condition we find in the survey
- The size of the system
Combining work into one visit or one programme often makes better use of the time. Mention every system or site you need covered, and you’ll get one fixed quote.
Asking for a quote
What to send for a quote:
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- The times we could work without disrupting the site
- Photos showing the whole system and its surroundings
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
To get a fixed quote, call us on 0345 646 2711, or send details by email with the site type, your trading hours and a short description of the system. A few pictures and your last certificate or report help a lot. You’ll typically have a quote within one working day.

When to call us in Thong
Wherever you are, Thong 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.
These are the problems we see most often:
- Filters left unwashed on busy weeks
- Blocked baffle filters
- Drips falling from the filters onto equipment
- Filters that come out of the sink still dirty
Cobham College, about 1.5 miles south, is one of the historic houses near Thong; if you run event catering at a venue like that, cleans can be booked between functions.

Why act early in Thong
Leaving filters too long pushes more grease into the plenum and ducts. That makes the next full clean a bigger job, and grease may build up faster than the cleaning interval allows. It’s simpler to plan the work at Thong now than to arrange it in a hurry later.
One small site or a whole estate, we price it on the same basis: what needs doing, how we get to it and when. You’ll have a fixed price before we start.

What a clean will not put right
We’ll always give you a straight diagnosis, so here’s what grease filter exchange will not do:
- An extract that was undersized from the start
- A fan that is failing or too weak for the system
- Greasy ducts and risers that a filter change will not reach
If in doubt, ring 0345 646 2711 or drop us a line and we will say what we think before booking.

FAQs for Thong
Can you clean school kitchen extracts in Thong during the holidays?
Yes, out-of-term visits are normal for schools. The FSA’s register shows about 18 schools and colleges with food registrations within roughly a mile and a half of Thong. Just phone us on 0345 646 2711, or send details by email with your term dates and we’ll plan around them.
Which fire and rescue service is responsible for Thong?
Fire safety enforcement in Thong is handled by Kent Fire and Rescue Service. A recent cleaning certificate and a note of the next clean date show that grease in the extract is being managed.
Is there a survey before the work?
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.
Do you have insurance?
Yes, fully. We also hold CHAS and SafeContractor, for sites that check contractor safety.
Can we book visits on a schedule?
Yes. Send details of the systems and how they’re used, and we will suggest a schedule and quote for it.
What’s TR19?
It’s BESA’s specification and the benchmark insurers, fire officers and EHOs look to. It sets out inspection, cleaning and record keeping and expects a risk-based approach.
Can you look after several sites?
Yes. Tell us the addresses and what each needs and you will get one fixed quote.
Will I get paperwork for my records?
Yes, always. It’s a dated, written report with pictures, plus a certificate via the BESCA Vent Hygiene Elite portal for TR19® Grease cleans. File it with your fire safety records.
Part by part
The plenum
A greasy plenum is a sign filters have been left too long, or that a full clean is due.
Busy restaurant and pub kitchens
When service is non-stop, filters get forgotten. A regular exchange means nobody has to remember.
What we do, step by step
There’s very little for your team to do on the day. Someone lets us in at the agreed time and shows us where everything is, and we take it from there. Before we leave, the area is tidied and the paperwork follows. Seeing the system in photos first means the trip to Thong can be planned properly.
- We record the number, size and type of your filters.
- We set the interval with you.
- On each visit, we remove the greasy filters.
- A clean set is fitted and checked for gaps.
- We take the greasy set away and confirm the next date.
Getting ready for the visit
- Move anything stored near the system
- Allow time for equipment near the work to be turned off and cool down
- Dig out any earlier paperwork for the system
