How we handle ductwork cleaning in Knox Bridge
We’ve been trading since 2009, working across London and the South East. As a BESCA Vent Hygiene Elite member, our duct cleaning is done to BESA TR19® Grease, with each certificate issued through the BESCA portal. The work covers attenuators, bends and junctions and access panels, and people most often call us about ductwork that has never been cleaned and grease pooling at the foot of the riser.
In a small place like Knox Bridge, kitchens are often in older or extended buildings, with long single-storey duct runs, where grease settles in the flat sections. We agree access and timings in advance.
Nothing is signed off by word of mouth: a written report, dated and illustrated with photos, and for TR19® Grease cleans, a certificate issued through the BESCA VHE portal. It shows what was done and what, if anything, couldn’t be reached.

In-house cleaning or a specialist?
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.
In-house cleaning and specialist cleaning do different jobs. Wiping filters daily and washing them weekly keeps the visible parts in order, but grease that has passed the filters is out of reach. That part needs specialist access and equipment.
Different parts, different methods
Access panels
Every section of duct is cleaned through an access panel. Without them, parts of the duct can’t be reached and the report has to say so.
Bends and transitions
The join where the canopy meets the duct is a common hotspot. We clean it from the canopy side or through a nearby panel.
Fixed quotes for ductwork cleaning in Knox Bridge
You’ll get a fixed price before work begins. It takes into account:
- How big the system is
- Site requirements such as sign-in and permits
- Access, including roofs, risers and ceiling voids
- One-off work versus a regular cycle
What you pay reflects the actual work. That’s why every job is surveyed first, and why the quote is fixed before we start.
Asking for a quote
When you contact us, it’s useful to have:
- A few general shots of the system
- Problems your staff have spotted
- Where the site is and what kind of site it is
- Your opening hours and when the area is out of use
Getting a quote doesn’t take long. Send a few details and pictures, and we normally reply with a fixed quote within one working day. Where a survey is needed, we arrange a time that suits the site.
Keeping the system healthy
So the system stays in good health:
- File each certificate and photo report in the maintenance log
- Diarise the next duct clean
- Ask us about extra access panels where sections cannot be reached
- Make sure filters are seated properly
After the clean, the same points are tested again, so the report shows the before and after figures. Before and after photos sit next to the numbers.
Keep to the cleaning interval on the report. A change in cooking hours may change the interval under BESA guidance, and grease thickness testing will show it.
Your questions about ductwork cleaning in Knox Bridge
Do you work overnight in Knox Bridge?
Yes. We work evenings, overnight and at weekends. That way a site in Knox Bridge does not have to lose a day’s trading. Tell us your opening hours when you ask for a quote.
Who would carry out a food hygiene inspection at a kitchen in Knox Bridge?
The local authority for Knox Bridge is Tunbridge Wells council, and its environmental health team does the inspecting. Ratings are published by the Food Standards Agency, so a clean extract and good records are worth keeping up.
Do you have a 24/7 line?
Yes. There’s a 24/7 emergency line for anything that cannot wait until a planned visit. Call us any time and explain what’s happened.
Can you look after several sites?
Yes. You deal with one contact for every site in our area, with visits on a regular schedule.
Do we lose a day’s trading?
Typically not. Out-of-hours visits keep the disruption down. Bigger sites can be done in stages so parts stay in use.
Do you look at the system first?
Yes, every time. We diagnose before we treat: the survey tells us what the system needs and how to reach it and the fixed quote is built on it.
What’s involved in cleaning extract ducts?
After a survey and grease readings, the duct is opened up through its access panels. We clean the runs and risers section by section, then the readings are repeated.
What is TR19?
A BESA specification in two main parts: TR19® Grease for kitchen extracts and TR19® Air for supply and extract systems. It is not law, but it’s the benchmark.
What happens on the day
Your trading hours come first. We book the visit for a time the area is closed, whether that’s an evening, overnight or a weekend. When the team arrives, the work area is protected and the relevant equipment is switched off to cool, and the job takes anything from a few hours to several visits, depending on the length of duct. The timing of a visit to Knox Bridge is set by you, and the travel is our side of the planning.
- We start by working out how the duct runs and where it can be opened.
- Grease readings are taken at set points along the duct.
- Through the access panels, thick grease is removed by hand first.
- The duct is degreased with the method that suits the grease, from degreasers to hot water or steam.
- Post-clean readings and pictures go into the report, with any unreachable section listed.
Preparing for the visit
- Have your last certificate or report to hand
- Let us know when the site is closed or quiet
- Let us know how we reach the system, including roofs, risers and plant rooms

- Grease seeping out of the duct seams
- An insurer asking for TR19 evidence
- A grease test showing the duct is overdue
Healthcare kitchens cannot easily close, so their extracts are cleaned overnight or between meal services; the nearest hospital to Knox Bridge is Benenden Hospital, about 4.4 miles south-east.
