TR19 inspection in Hemel Hempstead
Post-clean verification is a check carried out once the cleaning is done, with fresh grease readings, photos and a look at the areas that were cleaned. It shows whether the system was left in the condition the paperwork describes. The work covers wet film thickness tests, deposit thickness tests and pre-clean surveys, and common reasons people get in touch are ductwork where grease may be over the TR19 limits and confirming a clean reached the whole system.
Town-centre kitchens in a place like Hemel Hempstead often sit below flats or offices, and the extract can climb several storeys before it discharges. A riser needs proper access to be cleaned top to bottom, and anything we cannot reach goes on the report.
Good records are part of the job. You get a written report with photos after every visit, listing what was done, anything we couldn’t reach and when the next visit is due. Keep it with your fire safety records so it’s ready for an insurer, fire officer or EHO.

Signs you need TR19 inspection in Hemel Hempstead
Grease in a duct is flammable fuel. A flare-up on the range can be drawn into the canopy and duct, and from there a fire can spread through the ductwork. Knowing how much there is lets you act before it becomes a hazard.
Any of these means the system needs a check-up:
- Insurance renewals needing proof of TR19 cleaning
- Checking the result of a recent clean
- Extracts that may be over the 200 micron mean
- Kitchens whose menu or hours have changed
If you look after a school kitchen, at a school such as Broadfield Academy or anywhere near Hemel Hempstead, the holidays are the usual time for a TR19® clean.

Grease on the fan adds to wear. The inspection shows whether it needs cleaning now.
What affects the quote in Hemel Hempstead
Some jobs are bigger than they look, and some smaller. The main factors:
- The condition we find in the survey
- The number of sites or systems
- Parking and loading at the site
- How big the system is
No two sites are the same, so we price each one individually. Size, access, the condition of the system and when we can work all make a difference.
Asking for a quote
The more you tell us, the more accurate the quote. With your enquiry, please include:
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- Any symptoms, from odd noises to smells or leaks
- Your opening hours and when the area is out of use
- The paperwork from the last visit, if you have it
Need a price for TR19 inspection? Please give us a ring on 0345 646 2711, or send details by email and tell us about the site. We’ll explain what we’d do and send a fixed quote before you commit to anything.
What staff can safely do
In-house cleaning and specialist cleaning do different jobs. Wiping filters daily and washing them weekly keeps the visible parts in order, but grease that has passed the filters is out of reach. Reaching it takes a specialist with the right equipment.
Keep a record of what your team does. A simple log of filter washes, wipe-downs and checks helps show that the system is managed between specialist visits, alongside our reports.
Your questions about TR19 inspection in Hemel Hempstead
Which council inspects kitchens in Hemel Hempstead?
In Hemel Hempstead, it’s Dacorum council that carries out food hygiene inspections. An officer may look up into the canopy, so clean filters on the day and a recent certificate on file both help.
Can you come to Hemel Hempstead after we close?
Yes, nights and weekends are routine for us. The site is handed back ready to open. Tell us your opening hours when you ask for a quote.
At what point does grease need cleaning?
TR19® Grease says grease should not go over a mean of 200 microns between cleans. 500 microns or more at any point calls for immediate spot cleaning.
What types of premises do you cover?
Commercial premises of every kind: kitchens, offices, schools, healthcare, retail, leisure and food production. We fit the work around how the site operates.
Can we book visits on a schedule?
Yes, of course. Tell us what you have and how it’s used, and we will suggest a schedule and quote for it.
Do you look at the system first?
Yes, always. Diagnosis comes before treatment: the survey tells us what the system needs and how to reach it, and the quote is based on that.
Can you inspect our extract for our insurance company?
Yes, for kitchens across the South East and London. Tell us what your insurer has asked for and we’ll set the report out to match.
Do we have to follow TR19 by law?
No. TR19® is a specification, not a statute. In practice, an insurer can refuse or reduce a claim without proof of TR19 cleaning, so it matters in practice.
When something else is needed
Some problems need a different service or another trade:
- Installation problems, which fall under design guidance such as DW172
- Sections with no access, until panels are fitted
- The grease itself, which needs a full or spot clean
Not sure which it is? You can phone us on 0345 646 2711 or email us and we will tell you honestly before you book.

What TR19 inspection looks like in Hemel Hempstead
Look up Hemel Hempstead on the FSA’s food hygiene register and you’ll find about 108 restaurants, cafés and canteens and about 69 takeaways in Hemel Hempstead and the streets around it, up to about 1.5 miles out. Kitchens like these cook for very different hours, and grease testing shows which extracts need cleaning soonest. Hemel Hempstead sits within the area of Hertfordshire Fire and Rescue Service. In most workplaces, including commercial kitchens, it’s the fire and rescue authority that enforces the Fire Safety Order. In Hemel Hempstead, food businesses are inspected by environmental health officers from Dacorum council. The cleanliness of the kitchen and its equipment, extraction included, is part of what they check. A TR19® certificate and photo report after each clean gives you a record to show an inspector.
Older buildings often hide long, awkward duct runs, and if you run a kitchen at a historic venue in the area (High Elms Manor is about 4.6 miles south-east), access may need planning. Healthcare kitchens, like those at hospitals such as Hemel Hempstead Hospital (about 0.5 miles west), often cook for long hours, which puts them in BESA’s heavier-use bands.

What happens if it’s left?
Surveying first means the clean goes to plan. Access problems are spotted in advance rather than on the night, and the quote reflects the real job. If an insurer or inspector asks when the work was last done, an up-to-date certificate answers the question.
Whatever the type of site, the quote works the same way: how much there is, how we reach it, what state it’s in and when we can work. Ask for a fixed quote and we’ll go through it with you.

How the visit works
We turn up 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. The work itself takes a couple of hours for a typical kitchen extract system. Larger sites in Hemel Hempstead can be done in phases, out of hours, so part of the building keeps working.
- 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.
- Grease readings are taken and photos recorded.
- We report back with readings and a fixed quote.
Before we arrive
- Mention any sign-in, permit or induction we need
- Let us know how we reach the system, including roofs, risers and plant rooms
- Make sure equipment near the work can be switched off and left to cool
How to get a quote
Quoting starts with a diagnosis, either from pictures and details you send or from a site visit. After that, you get a fixed price for the work, before we start.
