TR19 inspection for kitchens and businesses in Knotty Green
Before any clean in Knotty Green, we survey the canopy, plenum, filters, ducts, fan and discharge. Access is checked along the full length, and record grease readings at set points. The work covers post-clean checks, access surveys and insurer audits, and the jobs we see most are kitchen extract systems with no recent grease readings and insurers asking for TR19 evidence.
In a small place like Knotty Green, kitchens are often in older or extended buildings, with long single-storey duct runs, where grease settles in the flat sections. Access, parking and timings are agreed before the day.
It’s worth checking any contractor’s accreditations. Ours are BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease, plus CHAS, SafeContractor and ISO 9001, with full insurance on top.

What happens if it’s left?
Surveying first means the clean goes to plan. Missing access panels, hidden duct runs and awkward fans are found before the cleaners arrive, and the quote reflects the real job. A planned visit to Knotty Green is easier to arrange than an emergency callout.
Kitchens, offices, schools and hospitals are all priced the same way: the size of the job, access, condition and working hours. Ask for a fixed quote and we’ll explain each part.

How it works
There’s very little for your team to do on the day. A contact on site lets us in at the agreed time and points us to the system, and we take it from there. Before we leave, the area is tidied and the paperwork follows. Somewhere like Knotty Green, lanes, gates and parking are worth mentioning in advance.
- We go through any past certificates and reports.
- We follow the extract from canopy to discharge.
- Access panels are located and any missing ones noted.
- We measure the grease and photograph each point.
- We report back with readings and a fixed quote.
Preparing for the visit
- Dig out any earlier paperwork for the system
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
- Mention any parking or loading restrictions
Ask for a quote
Quoting starts with a diagnosis, either from pictures and details you send or from a site visit. Then we send a fixed price, before we start.

Signs you need TR19 inspection in Knotty Green
Looking at a canopy tells you little about what’s in the duct. A system can look clean at the filters and be heavily coated further in, so readings are the reliable guide.
These are the problems we see most often:
- Systems that need surveying before cleaning
- Heavy grease suspected in the plenum or ducts
- Parts of the system left out of past cleans
- Uncertainty over how often to clean
A kitchen near Beaconsfield station that serves breakfast and dinner can run its extract twelve hours or more, which shortens the cleaning interval.
What your quote should include
- How VAT is shown on the quote
- What happens if part of the system can’t be accessed
- How they set the interval to the next visit
- If they look at the system before pricing

When it’s something else
TR19 inspection cannot fix everything, and we will tell you before work begins. It will not put right:
- Parts of the duct nobody can reach yet
- Design faults in the extract system
- Heavy deposits found on test, which still need cleaning
If you are not sure, just phone us on 0345 646 2711 or drop us a line and we will give you a straight answer.

Kitchen extracts in Knotty Green
Food Standards Agency data counts about 17 cafés, restaurants and staff canteens and about 4 takeaways within roughly a mile and a half of the centre of Knotty Green. Where they cook under a canopy, a grease reading is the way to tell whether the extract is due a clean. Knotty Green sits within the area of Buckinghamshire Fire and Rescue Service. 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. It’s Buckinghamshire council that sends environmental health officers to food businesses in Knotty Green. 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.
A hospital like Amersham Hospital, about 3.2 miles north-east, is the kind of site where a kitchen may cook for patients, staff and visitors all day. A hall kitchen that only cooks for events, whether near Church of St Michael and All Angels or elsewhere in Knotty Green, still needs its extract cleaned, just less often.

Aftercare tips
Here’s the after-treatment advice, in brief:
- Flag changes in how much frying the kitchen does
- Send TR19 audit reports to your insurer on request
- Keep access panels clear and unpainted
- Clean grease off the canopy between professional cleans
After the inspection, we send a report showing each reading, its location and pictures. File it alongside your TR19 certificates.
Keep filters clean and in place. Gaps around filters let grease get past them.
In-house cleaning or a specialist?
Keep a record of what your team does. A simple log of filter washes, wipe-downs and checks shows an inspector that the system is looked after between visits, alongside our reports.
When your team notices a problem between visits, like drips, unusual noise, smells or damaged filters, they should report it rather than try to fix it. We’ll take a look and give you a fixed quote.
Questions from Knotty Green
Which fire service covers Knotty Green?
It’s Buckinghamshire Fire and Rescue Service, which covers Knotty Green. Records of extract cleaning are a sensible thing to have ready if a fire safety officer carries out an audit.
Do you clean school canteen extracts around Knotty Green out of term?
Yes. The holidays are the usual time for school work. Around Knotty Green, the Food Standards Agency lists about 6 schools and colleges with registered kitchens within a mile and a half or so. Booking early in the term gives the best choice of holiday dates.
What is grease thickness testing?
The Wet Film Thickness Test (WFTT) and Deposit Thickness Test (DTT) measure how thick the grease is at a given point. We take readings at set points from canopy to fan.
How do you keep the site clean during the work?
We cover floors and nearby surfaces with sheeting before we start, and anything we remove is contained. At the end, the area is cleaned down.
What does TR19 inspection cost?
The cost depends on the size of the system, its condition, access and timing. Ask us for a fixed quote, normally ready within one working day.
Which kinds of sites do you work on?
Any site with a kitchen or a ventilation system to look after, from a small pub to a hospital. Hotels, schools, care homes, offices, shops and leisure sites are all part of our work.
Where does the waste go?
It leaves the site with us when we go. During the work, it’s contained so the area stays clean.
Can the work be done while we are closed?
Yes. Much of our work happens in the evening, overnight or at weekends, so you do not have to close during trading.
Multi-site and managed buildings
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 can quote for the whole system.
Facilities teams in offices, schools and healthcare sites book us too across Buckinghamshire. Work can be phased by floor, building or site around the people who use them.
