About our grease filter exchange in Preston
Washing filters in the kitchen sink is messy and easily missed on a busy week. An exchange service means clean filters arrive and greasy ones leave, so the canopy is never left without filters. The work covers island canopies, mesh filters and school and hospital kitchens, and the jobs we see most are filters that leave gaps in the canopy and a canopy running with filters missing.
Size doesn’t change the work: a kitchen in a place like Preston gets the whole system cleaned, canopy to discharge. We plan the visit around your hours, with the journey sorted in advance.
Insurers, fire officers and environmental health officers all look at records. So every job comes with a written report and pictures, plus a TR19® certificate through the BESCA VHE portal where the work is a TR19® Grease clean.

What grease filter exchange looks like in Preston
The coast is only about 3 miles from Preston. Metal on the roof weathers faster close to the coast, and the extract fan and cowl are no exception. Look up Preston on the FSA’s food hygiene register and you will find about 47 restaurants, cafés and canteens and about 14 sandwich bars and takeaways in and around Preston, up to about a mile and a half out. Clogged filters slow the airflow, and busy kitchens like these clog them fast. It’s Swale council that sends environmental health officers to food businesses in Preston. Extraction counts as kitchen equipment, so its condition can come up on the day. Before-and-after pictures from each clean are a simple way to show the extract is in hand.
Church and community hall kitchens, near St Catherine's Church or anywhere around Preston, are easy to forget, but their extracts collect grease like any other. 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 3.3 miles south-west), access may need planning.
Preston is about 7 miles south-west of Whitstable, in Kent. From the centre of Preston to the outskirts, grease filter exchange is available to all kinds of commercial premises, from small sites to large estates. Across Kent, we cover 922 places, and Preston is one of them. For sites nearby, see our Maidstone page, about 16 miles away.
Grease filter exchange in ME13 follows the same survey, fixed quote and written report as everywhere else we cover.

Near you in Preston
Locally, jobs take us to businesses close to Ethelbert Road Primary School, Oare Meadow and The Elephant pub. There’s a railway station in Preston itself: Faversham station. Nearby you will also find Newnham Castle (4.3 miles south-west).
Looking after it afterwards
Once we’ve finished, these simple steps help:
- Mention it if the kitchen gets busier
- Wipe the outside of the canopy as part of daily cleaning
- Tell us if a filter is bent or damaged
- Keep filter exchange and TR19 cleaning on the same plan
Keep an eye out for filters that have been taken out. Gaps let grease into the plenum so tell us if you need a replacement.
A kitchen that is getting busier needs its filters changed more often. Changing the interval early stops grease building up unseen behind the canopy.
Common problems we fix in Preston
The type of cooking matters. Fryers, grills and woks load filters faster than ovens and steamers so no single schedule suits every kitchen.
Look out for these warning signs:
- A greasy plenum behind the filters
- Staff short of time to wash filters
- Drips falling from the filters onto equipment
- Damaged filters letting grease past
Bursars and site managers at schools such as The Abbey School tend to book extract cleaning for when the kitchen is empty.
What to look for in a quote
- Whether a written report and photos are included
- When they can work, and whether that’s outside your opening hours
- Whether the whole system is included, or only the parts that are easy to reach
- How they set the interval to the next visit
What staff can safely do
Good housekeeping makes our visits easier, not unnecessary. Clean filters and tidy surfaces slow the build-up, but the parts you can’t see still need a specialist at the right interval.
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, next to our reports.

What else we do in Preston
How it works
Protection comes first: sheeting goes over floors and surfaces close to the work. Then we make the system safe and start. It takes a short visit, depending on how many filters the canopies hold, and we clear up before we go. For a site near Preston, the work is booked around your opening hours, evenings and weekends included.
- We count and measure the filters in every canopy.
- Together we set how often the filters should be changed.
- On each visit, the dirty filters come out of the canopy.
- Clean filters go straight back in, seated properly with no gaps.
- Anything we notice, such as bent filters or a dirty plenum, is pointed out.
Before we arrive
- Clear the space around the work
- Let us know about permits to work or site inductions
- Mention any parking or loading restrictions
Getting a quote
Photos are the quickest way to a quote: the system from a couple of angles, plus any access panels or hatches. Add the site type and your opening hours, and many jobs can be priced from that alone.

Honest limits
An honest diagnosis matters more to us than a booking, so here’s what grease filter exchange will not do:
- A heavily greased plenum or canopy, which needs cleaning to TR19
- A canopy too small for the cooking beneath it
- Smell complaints that need odour control equipment
Not sure which it is? You can phone us on 0345 646 2711, or send details by email and we’ll tell you honestly before booking.
What the work covers
- Wall canopies
- Baffle filters
- Mesh filters
- Island canopies
- School and hospital kitchens
- Restaurants and pubs
Leave it or put it right?
Grease dripping from the canopy is a sign the filters cannot hold any more. Drips land on surfaces and equipment below and that is the kind of thing inspectors look for. A site near Preston that has to close at short notice is hard to cover for.
Whatever the type of site, the quote works the same way: the size of the job, access, condition and working hours. Ask for a fixed quote and we will explain each part.

Preston questions
Does the sea air around Preston make a difference to grease filter exchange?
It can. Salt air reaches Preston, which is within about 3 miles of the coast, and it speeds up rust. A fan housing that’s rusting near the coast can fail sooner, so it’s worth catching early.
Do you do school kitchen extract cleaning in Preston in the summer holidays?
Yes. The holidays are the usual time for school work. Food Standards Agency records list about 8 schools, colleges and universities with registered kitchens within about a mile and a half of Preston. You can ring 0345 646 2711 or use the quote form with the dates the site is empty.
Which sectors do you work in?
Any commercial site with kitchens or ventilation, from a single café to a large school. We work with hotels, schools, care homes, offices, retail and leisure sites.
What does TR19 mean?
It’s the industry benchmark for cleaning ventilation and kitchen extract systems, written by BESA. It covers how systems are inspected, cleaned and checked, and it takes a risk-based approach.
What paperwork should we keep on file?
Anything that proves the system is maintained: reports, certificates, photos and your own cleaning or check logs. One maintenance log per site keeps it simple.
What happens if you cannot reach some of it?
The report shows them clearly. Often the fix is extra access, such as new panels in ductwork, and we can fit those.
Can one contract cover all our sites?
Yes. You deal with one contact for every site in our area, with visits on a regular schedule.
How much notice do you need?
The more notice, the better, particularly for night and weekend visits. Quotes normally come back within one working day, and emergencies are covered by our 24/7 line.
