TR19 inspection for kitchens and businesses in Nettlestead Green
TR19® Grease says grease should not exceed a mean of 200 microns between cleans, and 500 microns or more at any point needs immediate spot cleaning. Grease testing shows which side of those lines you are on. If you’re dealing with missing TR19 certificates or history and cleaning intervals that may not suit the kitchen, we can put it right.
Somewhere as small as Nettlestead Green, commercial kitchens are few: perhaps a pub, a school or care home kitchen, or a hall used for events. Each still has a canopy and duct that collect grease.
Duct Doctor has been trading since 2009, as a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we’re fully insured.

Multi-site and managed buildings
Under the Regulatory Reform (Fire Safety) Order 2005, the responsible person must assess and reduce fire risk, which may be the employer, owner, landlord, FM or managing agent. With shared responsibility, good records help everyone.
Multi-site operators often want one contractor and one number. We cover South East England and London, so visits at different addresses can be planned together and kept to a regular schedule.

What else we do in Nettlestead Green
Looking after it afterwards
A little care between visits keeps the system in better shape. Our advice:
- Clean grease off the canopy between professional cleans
- Keep TR19 certificates, readings and reports together
- Keep access panels clear and unpainted
- Clean or swap grease filters as often as the kitchen needs
After post-clean verification, file the results with the cleaning certificate. Together they show the system was cleaned and checked.
Keep all TR19 records together so you can produce them quickly.
Honest limits
A few issues sit outside what this work can do:
- Installation problems, which fall under design guidance such as DW172
- The responsible person’s own fire risk assessment
- Sections with no access, until panels are fitted
If in doubt, call 0345 646 2711 or send us an email and we will say what we think before booking.

Advice
What TR19 inspection looks like in Nettlestead Green
Food Standards Agency records list about 6 cafés, restaurants and staff canteens within about 1.5 miles of central Nettlestead Green. Where they cook under a canopy, a grease reading is the way to tell whether the extract is due a clean. Kent Fire and Rescue Service covers Nettlestead Green. Its fire safety officers can audit commercial kitchens, and grease in the extract is part of a kitchen’s fire risk. Food hygiene inspections in Nettlestead Green are the job of Maidstone council’s environmental health team. They look at how clean the premises and equipment are, and the kitchen extract is part of that. A dated certificate in the maintenance file answers the question before it’s asked.
Church and community hall kitchens, near St Mary's Church or anywhere around Nettlestead Green, are easy to forget, but their extracts collect grease like any other. If your kitchen is in a listed or historic building, like the houses around Nettlestead Green (Old Soar Manor is about 4.3 miles north-west), fitting access panels needs care.

What the work involves, part by part
Extract fan and discharge
Grease builds up on the fan blades and inside the housing. They’re included in the readings and pictures.
Canopy and plenum
Behind the filters, the plenum catches plenty of grease. We take readings there and photograph it on every inspection.
How we price TR19 inspection
There’s no set price list, because sites vary so much. What we look at:
- Whether we need access equipment or extra panels
- The condition we find in the survey
- A single visit or a regular plan
- Any permits to work or inductions
Every site is different, so each one gets its own fixed quote. The size of the job, how we reach it, its condition and the working hours all make a difference.

What we are called out for in Nettlestead Green
Kitchens change: a new menu, longer hours or more frying can all add grease. A cleaning interval set years ago may no longer fit.
What we’re most often called out for:
- Confirming a clean reached the whole system
- Insurance renewals needing proof of TR19 cleaning
- Pre-clean surveys before a first TR19 clean
- Cleaning intervals that may not suit the kitchen
If you run a café or takeaway near Yalding station, early starts and late finishes leave little time to clean, so overnight extract cleaning suits.
