About our ductwork cleaning in Lenham Heath
Nobody sees duct grease building, so nobody notices it until something goes wrong. Flames pulled in from the cooking line can ignite it, carrying a fire along the duct and into rooms far from the kitchen. Removing it is the whole point. Typical jobs include readings above 200 microns from a grease thickness test and proof of duct cleaning for the insurer, across attenuators, horizontal duct runs and access panels.
Somewhere as small as Lenham Heath, commercial kitchens are few: perhaps a pub, a school or care home kitchen, or a hall used for events. Every one of them still needs its extract kept clear of grease, whatever the size of the place.
The sign-off is always in writing: a written report, dated and illustrated with pictures, 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.

Common questions in Lenham Heath
Which fire and rescue service is responsible for Lenham Heath?
Fire safety enforcement in Lenham Heath is handled by Kent Fire and Rescue Service. A recent cleaning certificate and a note of the next clean date show that grease in the extract is being managed.
Do you work overnight in Lenham Heath?
Yes, out-of-hours work is a big part of what we do. The work in Lenham Heath can fit around your hours. Let us know the hours you’re closed and we’ll book within them.
Can extra access doors be added to the duct?
Yes, as part of our fits and repairs work. We place them where they help most, and we will recommend where.
How can I tell if my extract ducts are dirty?
A grease thickness test gives the answer. Using a Wet Film Thickness Test or Deposit Thickness Test, we check the grease at set points. A mean above 200 microns, or 500 microns at any point, means it’s due.
What if parts of the system can’t be reached?
Anything we cannot reach goes on the report, with photos where possible, and we tell you what would make it reachable, for example new access panels.
Do you have insurance?
Yes. We’re fully insured, and we can share the details when you need them.
Do you have a 24/7 line?
Yes, 24/7. Our office is open from 8am to 6pm on weekdays, with the emergency line covering every other hour.
Will I get a report after the ducts are cleaned?
Every clean comes with a photo report, plus a TR19 certificate when the whole system is cleaned. File them with the fire risk assessment.
How the visit works
There’s very little for your team to do on the day. Someone lets us in at the agreed time and shows us where everything is, and we take it from there. Before we leave, the area is tidied and the paperwork follows. Pictures of the system and its access let us plan the work in Lenham Heath before we set off.
- We trace the duct and find every way in.
- Grease thickness is measured at set points.
- Once the kitchen has closed, we protect the area and open the panels.
- Thick grease is scraped out, then the runs and risers are degreased.
- Panels are closed, readings and photos repeated, and unreachable sections recorded.
Preparing for the visit
- Arrange a key holder or contact on site
- Agree a time when the area can be out of use
- Tell us where we can park and unload
How to get a quote
Photos are the quickest way to a quote: wide shots of the system, close-ups of anything that worries you and how we’d get to it. Tell us what kind of site it is and when it’s open, and many jobs can be priced from that alone.

Signs you need ductwork cleaning in Lenham Heath
Grease settles fastest where the air slows down. Long horizontal runs, bends, changes in size and the foot of a riser all collect more, and those are the points we pay most attention to.
Look out for these warning signs:
- Thick crusts of old grease along the duct
- A duct clean needed for an insurer
- Grease pooling at the foot of the riser
- High readings at a recent grease test
Bursars and site managers at schools such as The Lenham School tend to book extract cleaning for when the kitchen is empty.

Part by part
Vertical risers
Risers often pass through floors and walls, where fire dampers may be fitted. We test those as a separate job.
Multi-storey and shared buildings
A duct that climbs several floors may be cleaned over more than one visit. Visits are planned around the building’s hours, out of hours where possible.
Kitchen extracts in Lenham Heath
Kent Fire and Rescue Service covers Lenham Heath. Fire and rescue authorities enforce the Fire Safety Order in most non-domestic premises, and in a kitchen that fire risk includes the grease in the extract. We cover Lenham Heath, about 41 miles from central London, as part of our work across London and the South East. The visit is fixed around your opening hours, not ours.
A hall kitchen that only cooks for events, whether near Church of the Holy Trinity or elsewhere in Lenham Heath, still needs its extract cleaned, just less often.

Fixed quotes for ductwork cleaning in Lenham Heath
Every site gets its own quote. This is what makes a difference:
- Travel, parking and unloading
- The scale of the work
- Whether it’s a one-off visit or part of a schedule
- Whether several sites go on one quote
What you pay depends on how big the system is, the condition it’s in and access to every part of it. You get a fixed price before any work starts, so there are no surprises.
What we need to know
Many jobs can be priced from pictures and some basics. Useful things to send:
- A few general shots of the system
- Close-ups of filters, grilles, hatches or access panels
- Your last certificate, test record or report
- Where the plant sits or the system leaves the building, such as a roof or outside wall
If you need ductwork cleaning in Lenham Heath, give us a ring on 0345 646 2711 or email us. Let us know the site type and the opening hours, and send photos or your last report if you can. A fixed quote normally follows within one working day.
Landlords, agents and facilities managers
Running several sites is easier with one contractor. We work across London and the South East, so a run of sites can go into one programme and kept on a regular cycle.
We work for landlords, managing agents and facilities managers as well as the people running the site. Shared systems, like a riser serving several units, need a clear agreement on who books the work, and we are happy to quote for all of it.
What your team can do, and what needs us
Your own staff can handle the daily basics: wiping canopies, washing grease filters and recording it in a log. Inside the ducts, risers and fan is specialist work, which is where we come in.
Good housekeeping makes our visits easier, not unnecessary. Regular in-house cleaning slows the build-up, but the parts you can’t see still need a specialist at the right interval.

Why it’s worth doing now in Lenham Heath
Under BESA guidance, the mean grease level should stay at or below 200 microns between cleans. Anywhere that reaches 500 microns or more needs immediate spot cleaning. Putting off the clean only pushes readings higher. Our emergency line runs 24/7, but a planned visit to Lenham Heath is calmer for everyone.
Putting the work off seldom saves money. Build-up, wear and faults tend to get worse, not better, and a neglected system can mean more work. If you are unsure, phone us on 0345 646 2711, or email photos and we’ll give you an honest view and a fixed quote.
