- An exchange schedule is agreed to suit your cooking.
- The dirty set is lifted out.
- Clean filters go in and we check they sit snugly.
- We take the greasy set away and confirm the next date.

About our grease filter exchange in Throwley Forstal
Cleaning filters by hand takes staff time and is easy to put off. An exchange service means clean filters arrive and greasy ones leave, so the canopy is never left without filters. Typical jobs include drips falling from the filters onto equipment and grease left in baffles after washing, across wall canopies, baffle filters and restaurants and pubs.
Rural kitchens often have long, low duct runs through a roof space or along an outside wall, and those horizontal sections are where grease settles. Access, parking and timings are agreed before the day.
For insurers and inspectors, the record counts. So every job comes with a written report and photos, and grease extract cleans come with a TR19® certificate issued through the BESCA Vent Hygiene Elite portal.

What happens if it’s left?
Leaving filters too long pushes more grease into the plenum and ducts. The ductwork then loads up faster, and grease may build up faster than the cleaning interval allows. A planned visit to Throwley Forstal is easier to arrange than an emergency callout.
What you pay reflects the actual work. That is why we survey first, from pictures or on site, and why the quote is fixed before any work starts.

Common questions in Throwley Forstal
Who is the fire and rescue service for Throwley Forstal?
Kent Fire and Rescue Service is the fire and rescue service for Throwley Forstal. Records of extract cleaning are a sensible thing to have ready if a fire safety officer carries out an audit.
Can the work in Throwley Forstal be done at night or at weekends?
Yes, evening, overnight and weekend work is normal for us. It means the site in Throwley Forstal keeps running as normal. Your opening times are the first thing we ask for.
What types of premises do you cover?
Any commercial site with kitchens or ventilation, from a small pub to a hospital. Hotels, schools, care homes, offices, shops and leisure sites are all part of our work.
What should go in our maintenance log?
The reports and certificates from each visit, plus your own logs. Insurers, fire officers and EHOs may all ask to see them, so keep them together and easy to find.
Does a filter exchange replace TR19 cleaning?
No. Filter exchange works between full cleans, not instead of them. TR19® cleaning covers the canopy, plenum, ductwork and fan and comes with a certificate and photo report.
How much notice do you need?
Book as early as you can for planned work, especially if the next clean or test is due soon. Emergencies are different, because our line is open 24/7.
Which accreditations do you hold?
CHAS, SafeContractor, ISO 9001 and BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease. We are fully insured and have been trading since 2009.
What types of filter do you exchange?
We exchange baffle and mesh filters. At the start, we note what your canopies use so every set we bring fits.

Keeping the system healthy
Here’s the after-treatment advice, short and simple:
- Clear anything stored on or near the canopy
- Watch for grease drips between visits
- Let us know if your cooking hours increase
- Report damaged filters so they can be replaced
Once the clean filters are in, the kitchen can cook straight away. We take the greasy filters with us to be cleaned.
Filters that are left too long stop protecting the system. A regular cycle keeps the rest of the system cleaner until the next TR19 clean.
Different parts, different methods
Mesh filters
Mesh filters use layers of metal mesh to trap grease. They clog quickly in a busy kitchen, so they need changing often.
Canopy filter housings
We check that filters sit snugly in the housing at each visit, because gaps let grease through.
Throwley Forstal kitchens: local notes
Kent Fire and Rescue Service covers Throwley Forstal. The Fire Safety Order puts the duty on whoever runs a kitchen to control its fire risk, and a greasy duct is fuel. Environmental health officers from Swale council inspect food businesses in Throwley Forstal. An officer looking round a kitchen will see the canopy, and grease there is hard to miss. Before-and-after pictures from each clean are a simple way to show the extract is in hand.
Older buildings often hide long, awkward duct runs, and if you run a kitchen at a historic venue in the area (Belmont House and Gardens is about 1.1 miles north), access may need planning.

When to call us in Throwley Forstal
Filters get bent and damaged with handling. A bent filter doesn’t seat properly and grease passes round them.
Most sites get in touch after spotting one of these:
- Grease collecting in the filter channels
- Hand-washed filters that still look greasy
- Grease dripping from the canopy
- Staff short of time to wash filters
Church and community hall kitchens, near Church of St Michael and All Angels or anywhere around Throwley Forstal, are easy to forget, but their extracts collect grease like any other.
