Grease filter exchange in Keycol, done properly
A filter service works alongside TR19® cleaning, not instead of it. Clean filters reduce the grease reaching the ducts though vapour still carries some grease past them. That is why the whole system still needs cleaning to TR19 at the right interval. We’re often asked to deal with filters left unwashed on busy weeks and bent or damaged filters that don’t sit properly, on school and hospital kitchens, wall canopies and restaurants and pubs.
Rural kitchens often have long, low duct runs through a roof space or along an outside wall, where grease settles in the flat sections. Access, parking and timings are agreed before the day.
The report is your system’s health record: a dated account with pictures of everything we did. Grease extract cleans are also certificated to TR19® Grease through the BESCA VHE portal and sits alongside the report.

Staff cleaning versus specialist work
Logging matters as much as cleaning. A dated log of in-house cleaning and checks shows an inspector that the system is looked after between visits, alongside our reports.
Good housekeeping makes our visits easier, not unnecessary. Clean filters and tidy surfaces slow the build-up, but hidden parts of the system still need specialist attention.
Multi-site and managed buildings
Where a tenant occupies the premises but the landlord owns the building, the lease normally sets out who maintains what. We’re happy to deal with either side and send the paperwork to whoever needs it.
Multi-site operators often want one contractor and one number. We work across London and the South East, so visits at different addresses can be planned together and kept to a regular schedule.
When it’s something else
An honest diagnosis matters more to us than a booking, so here’s what this work can’t put right:
- Grease behind the filters that a swap can’t remove
- A canopy that does not capture the vapour properly
- A noisy or failed extract fan
If in doubt, call 0345 646 2711 or email us and we will say what we think before you book.

What happens if it’s left?
Some kitchens in Keycol wash filters themselves to save the cost of a service, and that can work if it’s done thoroughly and on time. When it does not happen reliably, an exchange makes it automatic. Systems in rural buildings are often out of sight and out of mind.
We don’t list prices on the website, because the cost depends on the site in front of us. For a fixed quote, phone us on 0345 646 2711 or send us an email, and we’ll explain what it covers.

Grease filter exchange around Keycol
At about 3 miles from the coast, Keycol is close enough for sea air to matter. Salt in the air is hard on rooftop fans, discharge cowls and fixings, so we check them for corrosion as well as grease. The FSA’s food hygiene register shows about 10 restaurants, cafés and works canteens and about 12 takeaways within about 1.5 miles of central Keycol. Where they cook under a canopy, the grease filters are the first line of defence and clog quickly. Kent Fire and Rescue Service covers Keycol. In most workplaces, including commercial kitchens, it’s the fire and rescue authority that enforces the Fire Safety Order.
If you look after a school kitchen, at a school such as Borden Church of England Primary School or anywhere near Keycol, the holidays are the usual time for a TR19® clean. If you run a church or community hall kitchen, near Church of St Bartholomew or elsewhere in Keycol, its extract still collects grease from every lunch and event.

What happens on the day
Your trading hours come first. Most visits are booked for when the area is out of use, such as evenings, overnight, early mornings or weekends. Once we’re in, the area is sheeted and anything that has to be off is turned off and cooled, and the work takes a short visit, depending on how many filters the canopies hold. If you can send photos, we can arrive in Keycol knowing what to expect.
- First, we check the canopies and the filters in them.
- We note any filters that are bent, damaged or missing.
- Greasy filters are swapped for clean ones.
- The filters are checked for fit before we go.
- We tell you if the plenum or canopy needs a clean.
Before we arrive

- Mention any sign-in, permit or induction we need

Between visits
Looking after the system between visits is straightforward, and it helps at the next visit:
- Never leave gaps in the filter bank
- Don’t refit a filter that’s bent
- Keep the extract on whenever the range is in use
- Tell us if the menu or opening hours change
Your team carries on as normal, without the filter washing. Make sure we can reach the canopy on exchange day and let us know of any changes to opening hours.
If cooking has stepped up, the filter schedule should too. Changing the interval early stops grease building up unseen behind the canopy.
Keycol questions
Can a school canteen extract in Keycol be done out of term time?
Yes. Half-terms and the summer break are the natural time for school work. With about 9 schools and colleges on the FSA’s register within roughly a mile and a half of Keycol, it pays to plan holiday dates ahead. Tell us your holiday dates and we’ll book the visit for when the site is empty.
Do you work in villages like Keycol?
Yes, smaller places are covered as well as towns. Photos of the system and directions to the site help us plan the visit.
What types of filter do you exchange?
The common types of grease filter: baffle and mesh. Mention how many canopies you have when you get in touch and we’ll confirm it on site.
Can you give a price for filter changes?
We price it on the number of filters and the visit frequency. Tell us what you have and we’ll come back with a fixed quote, typically within one working day.
Which records should we keep?
Every certificate and report from each visit, kept together in your maintenance log with your in-house cleaning records. BESA says certificates should show the date, location and technician.
What’s TR19?
A BESA specification in two main parts: TR19® Grease for kitchen extracts and TR19® Air for supply and extract systems. It isn’t legislation, but it’s the standard people check against.
Can we book visits on a schedule?
Yes. We run scheduled maintenance contracts, set at the interval the system needs. The report from each visit recommends the next date.
Do we need to close the kitchen while filters are changed?
An exchange doesn’t take long, and can be booked outside service times. The clean set goes in as soon as the dirty one comes out.
