TR19 inspection in Long Marston, done properly
Think of a TR19 inspection as the diagnosis before the treatment. We look at the system, take grease readings and photograph what we find, so the quote and the clean fit the real system. Typical jobs include post-clean verification after another contractor’s clean and heavy grease suspected in the plenum or ducts, across insurer audits, pre-clean surveys and deposit thickness tests.
In a small place like Long Marston, kitchens are often in older or extended buildings, with long single-storey duct runs, and those horizontal sections are where grease settles. We agree access and timings in advance.
Every visit ends with a written report and pictures, so there’s a dated record of the work. Kitchen extract cleaning to TR19® Grease is certificated through the BESCA Vent Hygiene Elite portal.

What TR19 inspection can’t fix
An honest diagnosis matters more to us than a booking, so here’s what this work cannot put right:
- The grease itself, which needs a full or spot clean
- Fan breakdowns, which need a repair visit
- The responsible person’s own fire risk assessment
Not sure which it is? You can call 0345 646 2711 or email us and we’ll tell you honestly before booking.
Where we work
- Post-clean checks
- Deposit thickness tests
- Insurer audits
- Access surveys
- Pre-clean surveys
- Wet film thickness tests
What staff can safely do
Day-to-day cleaning is something your team can do: wiping canopies, washing grease filters and recording it in a log. What they can’t safely do is clean inside the ductwork, the fan or the risers, which is where we come in.
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 can diagnose it and quote.
Why deal with it now?
A pre-clean survey avoids surprises on the night. Access problems are spotted in advance rather than on the night, and the quote reflects the real job. A fault that closes a site in a village like Long Marston affects everyone who depends on it.
The price reflects the work, not guesswork. That’s why we survey first, from photos or on site, and why the quote is fixed before work begins.

What affects the quote in Long Marston
The diagnosis comes before the price. We look at:
- The condition we find in the survey
- How big the system is
- Site rules, permits and inductions
- The number of sites or systems
Several systems or sites on one quote can make for a more efficient booking. Mention every system or site you need covered and we will price it together.
What we need to know
A few details help us quote accurately. When you get in touch, it helps to send:
- The postcode and the type of business
- Your opening hours and when the area is out of use
- Problems your staff have spotted
- Any access panels or hatches you can see
To help us quote: where the site is, what it is and its opening hours, photos of the system and any previous report or certificate. Once you have those, ring 0345 646 2711, or send details by email.
What we do, step by step
We start by comparing what we find with the survey or your photos. If anything is different, we talk it through with the person on site before carrying on. After that, the work takes around an hour or two per canopy and duct system. A few photos of the system help us make the most of a visit to a place like Long Marston.
- First we look at the system’s cleaning history, if there is one.
- We follow the extract from canopy to discharge.
- We note where access panels are and where more are needed.
- We measure the grease and photograph each point.
- You get a report and a fixed quote for the clean.
Before we arrive
- Arrange a key holder or contact on site
- Mention any locked doors, roof access or ceiling voids
- Have your last certificate or report to hand
How to get a quote
Quotes are quick. Send a few details and pictures, and we typically reply with a fixed quote within one working day. Where a survey is needed, we arrange a time that suits the site.

Looking after it afterwards
Results last longer with the right care. Here’s what we suggest:
- Have the latest report ready for insurance renewals
- Diary the next grease test and clean
- Keep the route to access panels clear
- Keep TR19 certificates, readings and reports together
For an insurer audit, send them the report as it is, with readings, photos and any areas not accessible.
Test grease regularly instead of relying on the calendar. It shows if build-up is speeding up.
Long Marston kitchens: local notes
The FSA’s data shows about 3 bars, pubs and nightclubs registered in Long Marston and the streets around it, up to about 1.5 miles out. Breakfasts, bar meals and functions all put grease into the extract wherever they’re cooked. Kitchens in Long Marston get their food hygiene inspections from Dacorum council. Extraction counts as kitchen equipment, so its condition can come up on the day. Keeping each certificate and photo report on file helps show the extract is looked after. The fire and rescue service for Long Marston is Hertfordshire Fire and Rescue Service. In most workplaces, including commercial kitchens, it’s the fire and rescue authority that enforces the Fire Safety Order.
For schools such as Long Marston VA Church of England Primary School, kitchen extract cleaning is usually booked for the holidays, when the canteen is closed. Older buildings often hide long, awkward duct runs, and if you run a kitchen at a historic venue in the area (Ascott House is about 4.3 miles north), access may need planning.

Signs you need TR19 inspection in Long Marston
Insurers, fire officers and environmental health officers look to TR19® as the benchmark. TR19® itself is not law, but the Regulatory Reform (Fire Safety) Order 2005 requires the responsible person to assess and reduce fire risk, and grease in the extract is part of that risk.
These are the problems we see most often:
- Kitchens taken over with no cleaning records
- Sections of duct that cannot be reached
- Extracts that have never been grease tested
- Uncertainty over how often to clean
Church and community hall kitchens, near Church of All Saints (Church of England) or anywhere around Long Marston, are easy to forget, but their extracts collect grease like any other.

Your questions about TR19 inspection in Long Marston
Who would carry out a food hygiene inspection at a kitchen in Long Marston?
Kitchens in Long Marston are inspected by Dacorum council’s environmental health officers. An officer may look up into the canopy, so clean filters on the day and a recent certificate on file both help.
Can you get to a site in Long Marston?
Yes. Villages and rural sites across the South East are part of our work, Long Marston included. Let us know about access, parking and anything unusual about getting there when you book.
At what point does grease need cleaning?
Under TR19® Grease, the mean thickness should not exceed 200 microns between cleans. Any reading of 500 microns or more needs immediate spot cleaning.
Will you produce a report for our insurer?
Yes, for kitchens across the South East and London. Share the insurer’s request so the report addresses it.
Is there a survey before the work?
Yes. We always survey first, from your photos and details, or with a visit where necessary. Then you get a fixed quote.
Can the work be done while we are closed?
Yes. Much of our work happens in the evening, overnight or at weekends, so you don’t have to close during trading.
How do you protect the area?
We start with protection: floor sheeting and covers over nearby surfaces and equipment. We tidy up and take our waste away before we leave.
What do you do with what you remove?
Anything we remove is contained as we work and taken away with us, including grease, debris and dirty water. We do not leave it behind.
