What we do, step by step
Our technicians bring everything the work needs, from protective sheeting to tools and access equipment. All we need from you is clear access and the right equipment switched off. On site, the work takes a couple of hours for a typical kitchen extract system. Seeing the system in pictures first means the trip to Knockholt can be planned properly.
- Post-clean verification is booked once the clean is done.
- The same access points are opened up.
- We repeat the WFTT or DTT readings.
- We photograph each area to record how it was left.
- We report the findings and flag any areas that need more work.
Before we arrive
- Agree a time when the area can be out of use
- Tell us about site rules, permits or sign-in
- Make sure equipment near the work can be switched off and left to cool
Ask for a quote
Photos are the quickest way to a quote: the system from a couple of angles, plus any access panels or hatches. Tell us what kind of site it is and when it’s open, and we can price many jobs without a visit.
Advice
TR19 inspection in Knockholt, done properly
Insurance policies often require evidence of TR19® cleaning and inspection. Without it, a claim can be refused or reduced. A TR19 audit sets out the system’s condition, with readings and pictures, for sites in Knockholt and the rest of Kent. We’re often asked to deal with systems that need surveying before cleaning and heavy grease suspected in the plenum or ducts, across insurer audits, wet film thickness tests and deposit thickness tests.
In a village or hamlet like Knockholt, the kitchens that need extract cleaning are typically a pub, a school, a care home or a hall kitchen, wherever there is one. Every one of them still needs its extract kept clear of grease, whatever the size of the place.
Insurers, fire officers and environmental health officers all look at records. That’s why every job is written up in a report with photos, and grease extract cleans come with a TR19® certificate issued through the BESCA Vent Hygiene Elite portal.

What affects the quote in Knockholt
The diagnosis comes before the price. The main factors are:
- Working hours and out-of-hours timing
- Where the site is and how we reach it
- What state the system is in
- Whether we need access equipment or extra panels
Combining work into one visit or one programme often makes better use of the time. Mention every system or site you need covered, and you’ll get one fixed quote.
What to send for a quote
When you call or email, it’s useful to have:
- Close-ups of filters, grilles, hatches or access panels
- Your last certificate, test record or report
- When the site is open and when it’s quiet
- Wide photos of the system and the area around it
Every quote begins with a look at the system, either from photos and details you send or from a site visit. Then we send a fixed price, before any work starts.

Why it’s worth doing now in Knockholt
Catching heavy deposits early keeps the fix small. Ignored, the layer only gets thicker. A fault that closes a site in a village like Knockholt affects everyone who depends on it.
The cost depends on how big the system is, what state it’s in and how easy it is to reach. We give you a fixed price before we start, so you know where you stand.

Between visits
Good habits slow the build-up between visits. A few tips:
- Store grease readings where your insurer can see them
- Keep to the recommended interval
- Never cook with filters missing
- Flag changes in how much frying the kitchen does
The audit report is set out to pass straight to your insurer or broker, including readings, pictures and any inaccessible sections.
Clean, correctly fitted filters stop more grease reaching the duct. Gaps around filters let grease get past them.
TR19 inspection in Knockholt: the local picture
Fire safety in Knockholt falls to 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 Knockholt, food businesses are inspected by environmental health officers from Sevenoaks 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, like those at hospitals such as Orpington Hospital (about 3.6 miles north), often cook for long hours, which puts them in BESA’s heavier-use bands. Volunteers running a hall kitchen near St Katharine's Church, or anywhere in Knockholt, may not know when the extract was last cleaned, and a grease test settles it. If your kitchen is in a listed or historic building, like the houses around Knockholt (Down House is about 2.7 miles north-west), fitting access panels needs care.
Knockholt is about 4 miles north-west of Sevenoaks, in Kent. Knockholt gets the same approach as every site we work on: a survey first, a fixed quote, work timed around your hours and a report with photos. Knockholt is one of 922 places in Kent where we work for TR19 inspection. You can also see our page for London, about 16 miles away.

Common questions in Knockholt
Can you come to Knockholt after we close?
Yes, evening, overnight and weekend work is normal for us. The work in Knockholt can fit around your hours. Just call 0345 646 2711 or drop us a line with your opening times and we’ll plan around them.
Who is the fire and rescue service for Knockholt?
It’s Kent Fire and Rescue Service, which covers Knockholt. It’s worth keeping your fire risk assessment, TR19® certificates and photo reports together, ready to show.
Do we have to follow TR19 by law?
No, TR19® isn’t legislation. But the responsible person must assess and reduce fire risk under the Fire Safety Order 2005, which in a kitchen includes grease in the extract. Many insurance policies also require TR19 adherence.
Are you accredited?
BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease, plus CHAS, SafeContractor and ISO 9001. We are fully insured and have been trading since 2009.
What do you do to protect the area?
We cover floors and nearby surfaces with sheeting before any work starts, and waste is contained as we go. At the end, the area is cleaned down.
What do the grease readings need to be?
Under TR19® Grease, the mean thickness should not exceed 200 microns between cleans. Any reading of 500 microns or more needs immediate spot cleaning.
Can we book visits on a schedule?
Yes. Plans on a 3, 6 or 12-monthly cycle are available, to suit the system and how it’s used.
What happens on a pre-clean survey?
The survey covers the whole system, grease readings and access to each section. It lets us plan the clean and send you a fixed quote.
Multi-site and managed buildings
When the building owner and the occupier are different, the lease normally sets out who maintains what. We can quote either party and send the paperwork to whoever needs it.
Records are where multi-site compliance often slips. Each visit ends with a dated report and photos, ready to show insurers, fire officers or EHOs.
What the work involves, part by part
Horizontal duct runs
Bends and long runs can hold heavy deposits, well away from where anyone looks.
Restaurants, pubs and hotels
Kitchens that cook for long hours build up grease faster. Regular testing shows whether the cleaning interval keeps up.
