Ductwork Cleaning in Knockholt Pound
Looking for ductwork cleaning in Knockholt Pound? We survey first, send you a fixed quote and work around your opening hours, then sign off with a report and photos.
- Proof of duct cleaning for the insurer
- Hardened, baked-on grease in long horizontal runs
- Grease seeping out of the duct seams
Aftercare tips
Here’s the after-treatment advice, short and simple:
- Tell us if grease leaks from the ductwork
- Consider fitting panels where the report shows gaps
- Never cook with a filter missing
- Ask for a grease thickness test if the kitchen gets busier
Any section of duct we couldn’t reach is listed on the report, with the reason. We can fit access panels so those sections are cleaned next time.
Run the extract the whole time the kitchen is cooking. Moving air carries vapour through rather than letting it settle, so switching off early adds to the build-up.
About our ductwork cleaning in Knockholt Pound
Every duct has its own route. Some run a short distance to an outside wall, others climb several floors to the roof. The survey traces the route, so we know where to get in and how long it will take. If you’re dealing with an insurer asking for TR19 evidence and readings above 200 microns from a grease thickness test, we can help, from horizontal duct runs, multi-storey ducts and access panels onwards.
Work in a small place like Knockholt Pound starts with a call to agree access and timings, and the clean itself is the same full TR19® job as in any town: canopy, filters, duct, fan and discharge, with a certificate and photo report at the end.
Insurers, fire officers and environmental health officers all look at records. That’s why every job is written up in a report with photos, plus a TR19® certificate through the BESCA VHE portal where the work is a TR19® Grease clean.

In-house cleaning or a specialist?
In-house cleaning and specialist cleaning do different jobs. A daily filter wipe and a weekly filter wash keep grease down at the front of the system, but grease that has passed the filters is out of reach. Reaching it takes a specialist with the right equipment.
Your own staff can handle the daily basics: wiping down canopy surfaces, cleaning filters and keeping a simple log. Inside the ducts, risers and fan is specialist work, and that’s where we come in.
Knockholt Pound kitchens: local notes
There are about 3 restaurants, cafés and canteens in Knockholt Pound and the streets around it, up to about 1.5 miles out, according to the Food Standards Agency’s register. The duct above a busy canopy coats itself in grease long before anyone sees it. The fire and rescue service for Knockholt Pound is Kent Fire and Rescue Service. In most workplaces, including commercial kitchens, it’s the fire and rescue authority that enforces the Fire Safety Order. Food hygiene inspections in Knockholt Pound are the job of Sevenoaks council’s environmental health team. The cleanliness of the kitchen and its equipment, extraction included, is part of what they check. A dated certificate in the maintenance file answers the question before it’s asked.
Older buildings often hide long, awkward duct runs, and if you run a kitchen at a historic venue in the area (Down House is about 3.2 miles west), access may need planning.

What else we do in Knockholt Pound
Your questions about ductwork cleaning in Knockholt Pound
Can you come to Knockholt Pound after we close?
Yes, out-of-hours work is a big part of what we do. It means the site in Knockholt Pound keeps running as normal. When you phone us on 0345 646 2711 or email us, mention when the site is quiet.
Who inspects food businesses in Knockholt Pound?
That is Sevenoaks council, whose environmental health officers carry out food hygiene inspections in Knockholt Pound. It helps to keep the extract cleaning records with your food safety paperwork, so they’re ready if asked for.
What happens if you cannot reach some of it?
They’re listed in the report, never skipped quietly. The report says which parts couldn’t be reached and why, along with a quote to put access in.
Can you quote from pictures?
In many cases, yes. Photos of the system and the access, plus your opening hours and last report, are often enough. Larger or hidden systems need a survey on site first.
Who is responsible for fire safety on the premises?
The Fire Safety Order 2005 calls them the responsible person: often the employer, owner or occupier. In shared or managed buildings, a landlord, facilities manager or managing agent can share the duty.
Can we book visits on a schedule?
Yes. Send details of the systems and how they’re used and we’ll propose a schedule with a fixed quote.
What information do you need?
A short description and a few pictures plus the address and your hours. We will ask for anything else we need.
What is TR19?
TR19® is the BESA specification for keeping ventilation systems clean. Since 2019, TR19® Grease has been a standalone specification for grease in kitchen extract systems, while TR19® Air covers other supply and extract ductwork.
What a clean won’t put right
Ductwork cleaning can’t fix everything, and we will tell you before work begins. It does not solve:
- A duct that is too small or badly routed for the kitchen (a design issue)
- A failed fan motor at the end of the duct (a fan repair job)
- Duct sections that need replacing
Not sure which it is? You can phone us on 0345 646 2711 or email us and we will tell you honestly.

What we are called out for in Knockholt Pound
A greasy duct is a fire path, in Knockholt Pound as anywhere. Once it lights, fire can spread along the duct and into other areas, which is why the responsible person needs it under control.
Signs it’s time to call us include:
- Fat dripping from the ductwork
- Duct runs with no cleaning record
- A duct clean needed for an insurer
- A grease test showing the duct is overdue
Where a hall near St Katharine's Church, or anywhere in Knockholt Pound, hosts lunch clubs or events, its extract gathers grease just as a café’s does.

Part by part
Access panels
Access panels are the doors that let us into the duct. Without them, parts of the duct cannot be reached and the report has to say so.
Attenuators and discharge
The discharge is where the duct ends and air leaves the building. It can gather grease and mark the wall or roof around it, so it’s cleaned as far as safe access allows.
