How we handle grease filter exchange in Rough Common

A filter service works alongside TR19® cleaning, not instead of it. Fresh filters help limit what gets into the ductwork though vapour still carries some grease past them. That’s why the whole system still needs cleaning to TR19 at the right interval. We’re often asked to deal with grease left in baffles after washing and grease filters clogged with grease, on school and hospital kitchens, baffle filters 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. We agree access and timings in advance.

A written report with pictures follows every visit, so there’s a dated record of the work. Where the work is a TR19® Grease clean, the certificate is issued through the BESCA Vent Hygiene Elite portal.

Grease, kitchens and Rough Common

The FSA’s food hygiene register shows about 16 cafés, restaurants and staff canteens in Rough Common and the streets around it, up to about 1.5 miles out. Where they cook under a canopy, the grease filters are the first line of defence and clog quickly. Rough Common sits within the area of Kent Fire and Rescue Service. In most workplaces, including commercial kitchens, it’s the fire and rescue authority that enforces the Fire Safety Order. In Rough Common, food businesses are inspected by environmental health officers from Canterbury City council. An officer looking round a kitchen will see the canopy, and grease there is hard to miss. Keeping each certificate and photo report on file helps show the extract is looked after.

Healthcare kitchens cannot easily close, so their extracts are cleaned overnight or between meal services; the nearest hospital to Rough Common is Eastbridge Hospital of St Thomas the Martyr, about 1.6 miles south-east. A hall kitchen that only cooks for events, whether near Church of St. Gabriel or elsewhere in Rough Common, still needs its extract cleaned, just less often.

Rough Common is about 2 miles north-west of Canterbury, in Kent. Rough Common gets the same approach as every site we work on: diagnosis first, a fixed price, out-of-hours working where necessary and a written report with photos. Our Kent coverage runs to 922 places, Rough Common among them. You can also see our page for Maidstone, roughly 23 miles from Rough Common.

What we do, step by step

When we arrive, we check the system against the survey or the photos you sent. Anything unexpected is raised with you before we go further. From there, it takes a few minutes per canopy, longer for a large kitchen with several canopies. Rural roads and tight entrances are worth telling us about before a visit to Rough Common.

  1. We look at the canopies and the condition of the filters.
  2. Any damaged or missing filters are noted.
  3. Greasy filters are swapped for clean ones.
  4. The filters are checked for fit before we go.
  5. Anything that needs attention, such as a greasy plenum, is pointed out.

Before we arrive

  • Allow time for equipment near the work to be turned off and cool down
  • Tell us where we can park and unload
  • Agree a time when the area can be out of use

What a clean will not put right

A few issues sit outside what this work can do:

  • A canopy too small for the cooking beneath it
  • A fan that’s failing or too weak for the system
  • Grease behind the filters that a swap cannot remove

If you are not sure, just phone us on 0345 646 2711, or send details by email and we’ll give you a straight answer before you book.

Parts of the system we cover

  • Restaurants and pubs
  • Mesh filters
  • Wall canopies
  • School and hospital kitchens
  • Island canopies
  • Baffle filters

Staff cleaning versus specialist work

Your own staff can handle the daily basics: wiping down canopy surfaces, cleaning filters and keeping a simple log. What they cannot safely do is clean inside the ductwork, the fan or the risers, which is where we come in.

For ventilation and air handling systems, in-house care is mostly about checks: keeping grilles clear, noting unusual noise or smells and logging filter changes. Cleaning inside ducts and units is specialist work.

Your questions about grease filter exchange in Rough Common

Which fire authority looks after Rough Common?

Fire safety enforcement in Rough Common is handled by Kent Fire and Rescue Service. Records of extract cleaning are a sensible thing to have ready if a fire safety officer carries out an audit.

Do you work at weekends in Rough Common?

Yes, out-of-hours work is a big part of what we do. That way a site in Rough Common does not have to lose a day’s trading. Just call us on 0345 646 2711, or email photos with your opening times and we will plan around them.

What if some of our filters are damaged?

A badly damaged filter should be replaced. We will tell you which ones and why on the visit.

Can you set up regular visits?

Yes. Regular plans can run on 3, 6 or 12-monthly cycles, to suit the system and how it’s used.

What does TR19 mean?

TR19® is the BESA specification for keeping ventilation systems clean. TR19® Grease, a standalone specification since 2019, covers grease in kitchen extract systems, and TR19® Air covers general supply and extract systems.

That depends on the slot you want and the size of the job. Tell us your preferred dates when you ask for a quote, and for anything urgent, ring our 24/7 emergency line.

The common types of grease filter: baffle and mesh. Tell us what you have when you call 0345 646 2711, or email photos and we’ll confirm it on site.

What happens if you cannot reach some of it?

Anything we cannot reach goes on the report, with photos where possible, and we explain what access is needed, such as extra access panels in ductwork.

Why it’s worth doing now in Rough Common

You won’t find a price list here, because each job is priced on what it involves. Call for a fixed quote, and we’ll talk you through it.

What we are called out for in Rough Common

Sometimes a filter is taken out and never put back. Every gap in the filter bank lets grease straight into the plenum where it settles out of sight.

These are the problems we see most often:

  • Filter washing that keeps being missed
  • Gaps where filters have been removed
  • A canopy that drips grease
  • Smoke and heat lingering under the hood

If you look after a school kitchen, at a school such as Blean Primary School or anywhere near Rough Common, the holidays are the usual time for a TR19® clean.

Questions to ask before booking

Different parts, different methods

The plenum

The plenum is the space behind the filters. It collects whatever grease the filters miss.

Baffle filters

Baffle filters use overlapping metal blades that force the air to change direction. Grease is thrown out of the airstream and collects on the baffles.
