Your questions about TR19 inspection in Colliers End
Do you work in villages like Colliers End?
Yes, smaller places are covered as well as towns. Photos of the system and directions to the site help us plan the visit.
Which fire service covers Colliers End?
Hertfordshire Fire and Rescue Service is the fire and rescue service for Colliers End. Records of extract cleaning are a sensible thing to have ready if a fire safety officer carries out an audit.
How much time does an inspection need?
Testing takes anything from an hour for a small canopy and short duct to a good part of a day for a large site. Large or multiple systems take longer, and you can give us a ring on 0345 646 2711 or use the quote form to book it in.
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.
What does a pre-clean survey involve?
A survey finds out how the system is laid out, how dirty it is and what can be reached, so the clean goes to plan. Any access problems are flagged so they can be sorted first.
What happens to the waste?
It’s contained and taken away. We collect grease, debris and waste water as we go rather than letting it spread.
Is TR19 a legal requirement?
No. TR19® is a specification, not a statute. Without TR19 records, an insurance claim can be reduced or refused, so it matters in practice.
Do you check other contractors’ cleans?
A post-clean check records grease readings and photos after the work, whoever did the clean.
About our TR19 inspection in Colliers End
Many insurers ask for proof that kitchen extract systems are cleaned and inspected to TR19®. Missing records can lead to a claim being reduced or refused. A TR19 audit sets out the system’s condition, with readings and photos, for sites in Colliers End and the rest of Hertfordshire. We’re often asked to deal with systems cleaned on a calendar with no measurements and kitchens taken over with no cleaning records, across post-clean checks, wet film thickness tests and deposit thickness tests.
For a kitchen in or near Colliers End, the visit is planned around opening hours and the journey, and the clean covers the whole system, as it would anywhere: canopy to discharge, then a TR19® certificate and a photo report.
Our accreditations include CHAS, SafeContractor and ISO 9001, and we are fully insured. On top of that, we’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we have been trading since 2009.

At about 26 miles from central London, Colliers End sits well inside the area we cover. We work evenings, overnight and at weekends, so the visit fits around the site. Kitchens in Colliers End get their food hygiene inspections from East Hertfordshire council. An officer looking round a kitchen will see the canopy, and grease there is hard to miss. A TR19® certificate and photo report after each clean gives you a record to show an inspector.
Where a hall near St Mary's, or anywhere in Colliers End, hosts lunch clubs or events, its extract gathers grease just as a café’s does. Term dates shape school work: for a school like Ralph Sadleir Middle School, an extract clean fits neatly into a half-term or summer break.

When something else is needed
An honest diagnosis matters more to us than a booking, so here’s what this work can’t put right:
- Sections with no access, until panels are fitted
- Design faults in the extract system
- Fan breakdowns, which need a repair visit
If you are not sure, just phone us on 0345 646 2711 or send us an email and we will give you a straight answer.
Where we work
- Pre-clean surveys
- Access surveys
- Post-clean checks
- Insurer audits
- Wet film thickness tests
- Deposit thickness tests
Keeping the system healthy
To keep the system working properly between visits:
- Look out for grease drips round the canopy edge
- Mention new equipment or longer hours at the next test
- Never cook with filters missing
- Wipe the canopy surfaces regularly
You get a report with the grease readings, where they were taken and pictures of each point. Keep it with your fire safety and TR19 records.
Keep all TR19 records together so the history is easy to show.
What your team can do, and what needs us
Logging matters as much as cleaning. A simple log of filter washes, wipe-downs and checks shows an inspector that the system is looked after between visits, alongside our reports.
If your staff spot something between visits, like drips, unusual noise, smells or damaged filters, it’s best reported rather than tackled in-house. We will take a look and give you a fixed quote.
Why act early in Colliers End
Without readings, you’re guessing when to clean. If grease reaches 500 microns anywhere, TR19® Grease calls for immediate spot cleaning, which you won’t know without measuring. If the system at a site near Colliers End fails, there may be nowhere nearby to move to.
Every site is different, so we price each one individually. Size, access, the condition of the system and when we can work all make a difference.

What happens on the day
On the day, we arrive at the time agreed with you, often in the evening, overnight or at the weekend so the site keeps working. Equipment that has to be off is switched off and allowed to cool first, and the area around the work is covered and protected. On site, it takes a couple of hours for a typical kitchen extract system. Seeing the system in photos first means the trip to Colliers End can be planned properly.
- First we book a time that won’t disrupt cooking.
- We look over the canopy, plenum, ducts, fan and discharge.
- Grease readings are taken at set points using WFTT or DTT.
- We photograph the test points and record any sections we cannot reach.
- We send a report setting out the readings, photos and next steps.
Before we arrive
- Agree a time when the area can be out of use
- Let us know how we reach the system, including roofs, risers and plant rooms
- Name a contact who can let us in at the agreed time
How to get 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 many jobs can be priced from that alone.

Do you need TR19 inspection in Colliers End?
Looking at a canopy tells you little about what’s in the duct. Clean filters can hide a heavy layer behind them, which is why readings matter.
If you notice any of these, it’s worth a diagnosis:
- Pre-clean surveys before a first TR19 clean
- An insurer’s request for a TR19 audit
- Missing TR19 certificates or history
- Extracts that have never been grease tested
