About our TR19 inspection in Nuthurst
BESA’s minimum cleaning frequencies depend on how long the kitchen cooks each day: every 3 months for heavy use of 12 to 16 hours a day, every 6 months for moderate use of 6 to 12 hours, and every 12 months for light use of 2 to 6 hours. Those are minimums, and grease readings help set the real interval. If you have sites with gaps in their extract records and kitchen extract systems with no recent grease readings, we can help, from insurer audits, post-clean checks and access surveys onwards.
In a small place like Nuthurst, kitchens are often in older or extended buildings, with long single-storey duct runs, where grease settles in the flat sections. We agree access and timings in advance.
The sign-off is always in writing: a written report, dated and illustrated with photos, plus a certificate through the BESCA Vent Hygiene Elite portal when the work is a TR19® Grease clean. It shows what was done and what, if anything, couldn’t be reached.

What happens if it’s left?
If a kitchen in Nuthurst has been cleaned on the same calendar for years, there’s no way to know if that interval is right without measuring. Testing gives you the evidence to set it properly. A fault that closes a site in a village like Nuthurst affects everyone who depends on it.
Putting the work off seldom saves money. Build-up, wear and faults tend to get worse, not better, which can make the next visit longer. If you are not sure what’s needed, phone us on 0345 646 2711 or drop us a line and we will give you an honest view and a fixed quote.

Your questions about TR19 inspection in Nuthurst
Which environmental health team covers Nuthurst?
That is Horsham council, whose environmental health officers carry out food hygiene inspections in Nuthurst. Ratings are published by the Food Standards Agency, so a clean extract and good records are worth keeping up.
Is Nuthurst within the area you cover?
Yes. Nuthurst is within the area we cover across London and the South East. Photos of the system and directions to the site help us plan the visit.
Can one contract cover all our sites?
Yes. You deal with one contact for every site in our area, with visits on a regular schedule.
Do we have to follow TR19 by law?
No. TR19® is BESA’s specification and the industry benchmark, not legislation. The law is the Fire Safety Order 2005, under which the responsible person must manage fire risk, and TR19® is what insurers and fire officers look to.
What happens to the waste?
We contain it and take it with us. Grease, debris and waste water are collected as the work goes on rather than letting it spread.
What is post-clean verification?
We visit after a clean, take readings at set points and photograph the system. The report flags anything missed.
How much notice should we give?
Earlier is better, especially for out-of-hours work. Quotes usually come back within one working day, and emergencies are covered by our 24/7 line.
How much does TR19 inspection cost?
It depends on the site, so we quote each one individually. For a quote, phone us on 0345 646 2711 or drop us a line with the site type, opening hours and a few photos.
When it’s something else
We will not sell you work that does not address the problem, so these are the things it won’t cover:
- Sections with no access, until panels are fitted
- Ductwork that was designed or installed badly
- The legal duty, which stays with the responsible person
If you’re not sure, just call 0345 646 2711 or drop us a line and we will give you a straight answer before you book.
Where we work
- Insurer audits
- Pre-clean surveys
- Deposit thickness tests
- Wet film thickness tests
- Post-clean checks
- Access surveys
Aftercare tips
To keep the system working properly between visits:
- Mention new equipment or longer hours at the next test
- Keep grease filters clean and fitted properly
- Keep the route to access panels clear
- File every inspection report with your certificates
The report recommends when the system should next be cleaned and tested, based on the readings and how the kitchen is used.
Keep filters clean and in place. Missing or damaged filters let grease straight into the plenum.
For landlords and multi-site operators
Facilities teams in offices, schools and healthcare sites book us too in Nuthurst and across West Sussex. Work can be phased by floor, building or site around the people who use them.
Keeping records across a portfolio is half the battle. Each visit produces a dated report with photos, so you can show an insurer or inspector what was done at each site.
What we do, step by step
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. Afterwards, the area is left tidy and the written report follows. Somewhere like Nuthurst, lanes, gates and parking are worth mentioning in advance.
- We go through any past certificates and reports.
- The layout is traced from the canopy to the discharge.
- Access panels are located and any missing ones noted.
- We measure the grease and photograph each point.
- You get a report and a fixed quote for the clean.
Preparing for the visit
- Agree a time when the area can be out of use
- Mention any locked doors, roof access or ceiling voids
- Tell us where we can park and unload

TR19 inspection in Nuthurst: the local picture
Nuthurst is covered by West Sussex 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. In Nuthurst, food businesses are inspected by environmental health officers from Horsham council. The cleanliness of the kitchen and its equipment, extraction included, is part of what they check. Keeping each certificate and photo report on file helps show the extract is looked after.
A hospital like Horsham Hospital, about 3.4 miles north, is the kind of site where a kitchen may cook for patients, staff and visitors all day. School kitchens, at schools like St Andrew's CofE Primary School for example, are usually cleaned in the holidays so no lunches are lost.
Nuthurst is about 3 miles south of Horsham, in West Sussex.

Part by part
Canopy and plenum
The plenum behind the filters can carry a lot of grease. Readings and photos are taken in the plenum on every inspection.
Restaurants, pubs and hotels
Kitchens that cook for long hours build up grease faster. Readings show if the cleans are frequent enough.
Signs you need TR19 inspection in Nuthurst
As hot, greasy air travels up the duct, it cools and leaves a film behind. The thickest layers can sit out of sight in the plenum, at bends and along flat runs.
Keep an eye out for any of the following:
- Post-clean verification after another contractor’s clean
- Insurance renewals needing proof of TR19 cleaning
- Extracts that have never been grease tested
- Sites with gaps in their extract records
Where a hall near The Parish Church of St Andrew, or anywhere in Nuthurst, hosts lunch clubs or events, its extract gathers grease just as a café’s does.
