TR19 inspection in Norton from ventilation hygiene specialists trading since 2009. Out-of-hours visits and 24/7 emergency callout.

In-house cleaning or a specialist?
If your staff spot something between visits, such as dripping grease, a noisy fan, a smell or a filter that won’t come clean, they should report it rather than try to fix it. We will take a look and give you a fixed quote.
Logging matters as much as cleaning. A dated log of in-house cleaning and checks shows an inspector that the system is looked after between visits, alongside our reports.
TR19 inspection for kitchens and businesses in Norton
Insurance policies often require evidence of TR19® cleaning and inspection. Missing records can lead to a claim being reduced or refused. Our TR19 audits give sites in Norton and across Hertfordshire a clear record of the system’s condition. We are often asked to deal with ductwork where grease may be over the TR19 limits and insurance renewals needing proof of TR19 cleaning, across insurer audits, deposit thickness tests and access surveys.
In a village or hamlet like Norton, the kitchens that need extract cleaning are usually a pub, a school, a care home or a hall kitchen, wherever there is one. Each still has a canopy and duct that collect grease, whatever the size of the place.
Think of the report as the system’s health record: a dated account with photos of everything we did. For TR19® Grease cleans, the certificate comes through the BESCA Vent Hygiene Elite portal and sits alongside the report.

Norton questions
Can you get to a site in Norton?
Yes. Norton is within the area we cover across London and the South East. Just mention lanes, gates or anything else about the site when you book.
Can you clean school kitchen extracts in Norton during the holidays?
Yes, and it’s the easiest time to do it. Food Standards Agency records list about 13 schools, colleges and universities with registered kitchens within about a mile and a half of Norton. Just give us a ring on 0345 646 2711 or send us an email with your term dates and we’ll plan around them.
Do you carry out TR19 audits for insurers?
Yes, for kitchens across the South East and London. Share the insurer’s request so the report addresses it.
What should I send you?
Just the basics: where it is, what kind of site, when it’s open and the access. Photos and the last report help too. Then call us on 0345 646 2711 or use the quote form.
How long does grease testing take?
Expect it to take a morning or less for one kitchen, more where there are several systems. We fit it around when the kitchen is closed or quiet.
What grease levels does TR19 allow?
Between cleans, the mean should stay at 200 microns or below, and anywhere at 500 microns or more needs spot cleaning straight away.
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.
Can you quote from photos?
In many cases, yes. With good photos, the site type and your last report, we can price many jobs. Where we can’t see enough, we arrange a survey.

Signs you need TR19 inspection in Norton
Not every section of a kitchen extract is easy to get to, so those sections can be skipped time and again. A survey finds the sections that can’t be reached, so panels can be fitted.
These are the problems we see most often:
- Ductwork where grease may be over the TR19 limits
- Kitchens whose menu or hours have changed
- Insurers asking for TR19 evidence
- Extracts that have never been grease tested
Bursars and site managers at schools such as Norton St Nicholas CofE (VA) Primary School tend to book extract cleaning for when the kitchen is empty.

How the job changes from site to site
Extract fan and discharge
We look at where the extract discharges outside, since grease reaches the very end of the system.
Restaurants, pubs and hotels
Kitchens that cook for long hours build up grease faster. Regular testing shows whether the cleaning interval keeps up.
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 the rest is down to us. Before we leave, the area is tidied and the paperwork follows. Pictures of the system and its access let us plan the work in Norton before we set off.
- First we book a time that won’t disrupt cooking.
- Every part of the system is examined, end to end.
- We take WFTT or DTT readings at set points along the system.
- We photograph the test points and record any sections we can’t reach.
- We send a report setting out the readings, photos and next steps.
Before we arrive
- Mention any locked doors, roof access or ceiling voids
- Agree a time when the area can be out of use
- Clear loose items from the work area

Leave it or put it right?
Without readings, you’re guessing when to clean. Any reading of 500 microns or more needs immediate spot cleaning under TR19® Grease, and you can only act on that if you’ve measured it. Out of sight is the usual reason a rural system goes too long without attention.
When the work has to happen, how we reach it and how big the site is can all change the price. We take each of them into account and give you a fixed price before work begins.

Managing agents and facilities teams in Norton
Managing agents often deal with us directly. Send the address, what’s needed and how access works, and we will send a fixed quote.
Facilities teams in offices, schools and healthcare sites book us too in Norton and across Hertfordshire. Larger estates can be phased building by building to keep disruption down.
Between visits
Think of this as the after-treatment advice, short and simple:
- Keep canopy edges and gutters wiped down
- Store grease readings where your insurer can see them
- Send TR19 audit reports to your insurer on request
- Mention new equipment or longer hours at the next test
Each report suggests the next clean and the next test, based on the readings and how the kitchen is used.
Keep certificates, reports and readings in one place so the history is easy to show.
TR19 inspection around Norton
The FSA’s food hygiene register shows about 76 cafés, restaurants and staff canteens and about 37 sandwich bars and takeaways across Norton and its immediate surroundings (about a mile and a half). Kitchens like these cook for very different hours, and grease testing shows which extracts need cleaning soonest. Norton is covered by Hertfordshire 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. Environmental health officers from North Hertfordshire council inspect food businesses in Norton. Extraction counts as kitchen equipment, so its condition can come up on the day. Before-and-after pictures from each clean are a simple way to show the extract is in hand.
If you run a church or community hall kitchen, near Church of St Nicholas or elsewhere in Norton, its extract still collects grease from every lunch and event. Healthcare kitchens cannot easily close, so their extracts are cleaned overnight or between meal services; the nearest hospital to Norton is Fairfield Hospital, about 1.6 miles west.
