How we handle TR19 inspection in Adeyfield
A fixed schedule does not always match how a kitchen really cooks. Some kitchens build up grease faster than the minimum intervals assume, and only measurement shows it. We give your risk assessment measured figures rather than guesses. The work covers insurer audits, wet film thickness tests and post-clean checks, and the jobs we see most are kitchen extract systems with no recent grease readings and heavy grease suspected in the plenum or ducts.
Size does not change the work: a kitchen in a place like Adeyfield gets the whole system cleaned, canopy to discharge. We plan the visit around your hours, with the journey sorted in advance.
Our accreditations include CHAS, SafeContractor and ISO 9001, and we are fully insured. We are also a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, trading since 2009.

Your questions about TR19 inspection in Adeyfield
Who inspects food businesses in Adeyfield?
In Adeyfield, 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.
Do you cover smaller places like Adeyfield?
Yes. Adeyfield is within the area we cover across London and the South East. A survey first, from photos or a visit, means we arrive with the right kit.
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 time does an inspection need?
Typically, the inspection takes an hour or two for a single kitchen, longer for a large or complex system. System size and access decide the rest.
What should I send you?
The site address, the type of premises and your opening hours, along with a few photos and any previous report.
How often should a kitchen extract be inspected?
Often enough to know the mean stays under 200 microns between cleans. The readings themselves tell you if the interval needs to change.
What’s TR19?
A BESA specification, with two parts that matter most here: TR19® Grease for kitchen extract systems and TR19® Air for general ventilation. It is not law, but it’s the benchmark.
Where does the waste go?
We take it away at the end of the visit. During the work, it’s contained so the area stays clean.
What staff can safely do
For ventilation and air handling systems, in-house care is mostly about checks: clear grilles, a log of filter changes and reporting anything odd. The inside of ducts and units needs a specialist.
Day-to-day cleaning is something your team can do: wiping canopies, washing grease filters and recording it in a log. Inside the ducts, risers and fan is specialist work, and that is where we come in.
Grease, kitchens and Adeyfield
According to Food Standards Agency records, there are about 29 pubs and bars and about 4 hotels and guest houses in Adeyfield 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 Adeyfield get their food hygiene inspections from Dacorum council. They look at how clean the premises and equipment are, and the kitchen extract is part of that. A dated certificate in the maintenance file answers the question before it’s asked. The fire and rescue service for Adeyfield is Hertfordshire Fire and Rescue Service. The Fire Safety Order puts the duty on whoever runs a kitchen to control its fire risk, and a greasy duct is fuel.
Batchwood Hall, about 4.2 miles east, is one of the historic houses near Adeyfield; if you run event catering at a venue like that, cleans can be booked between functions. If you look after a school kitchen, at a school such as Hobletts Manor Infants' School or anywhere near Adeyfield, the holidays are the usual time for a TR19® clean.

Multi-site and managed buildings
We also work for facilities teams across offices, schools and healthcare in Adeyfield and across Hertfordshire. Larger estates can be phased building by building around the people who use them.
From a single site to a large estate, the standard is the same: the system surveyed, the price fixed, the visit fitted around trading and everything written up afterwards.
Signs you need TR19 inspection in Adeyfield
Grease in a duct is flammable fuel. Flames from the range can be pulled into the canopy and travel through the ducts to other parts of the building. Measuring it is the first step to keeping it under control.
Any of these means the system needs a check-up:
- Ductwork where grease may be over the TR19 limits
- Insurers asking for TR19 evidence
- Missing access panels found on survey
- Systems cleaned on a calendar with no measurements
Church and community hall kitchens, near St Barnabas or anywhere around Adeyfield, are easy to forget, but their extracts collect grease like any other.
What your quote should include
- Whether the figure could change on the day
- Their accreditations, such as BESCA Vent Hygiene Elite, CHAS or SafeContractor
- Whether inaccessible sections are listed on the report
- Whether the quote is based on a survey or pictures
Why deal with it now?
Sites in Adeyfield that have never measured grease can’t tell whether their cleaning interval suits the kitchen. Measured readings let a competent person set the interval. It’s easy to lose track of when the work was last done on a quieter site.
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 will explain each part.
Why us?
- Accredited under CHAS and SafeContractor, with ISO 9001
- Fixed quotes, normally within one working day
- Survey first, then a fixed quote
- Trading since 2009

How it works
When we arrive, we check the system against the survey or the pictures you sent. If anything is different, we talk it through with the person on site before carrying on. After that, the work takes a couple of hours for a typical kitchen extract system. For a place like Adeyfield, we load the van from the survey notes so the work can be done in one visit where possible.
- Post-clean verification is booked once the clean is done.
- We open the access points used on the clean.
- We repeat the WFTT or DTT readings.
- Photos are taken to show the condition after the clean.
- The results are reported, with anything missed flagged.
Before we arrive
- Mention any sign-in, permit or induction we need
- Let us know when the site is closed or quiet
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
Get a fixed quote
Getting a quote does not take long. Call or email with a few details and you’ll typically have a fixed price within one working day. If we need to see the system first, we book a survey around your hours.
Advice
Keeping the system healthy
Simple habits between visits make a real difference. Our advice:
- Keep the route to access panels clear
- Look out for grease drips round the canopy edge
- Diary the next grease test and clean
- Have the latest report ready for insurance renewals
The audit report is set out to pass straight to your insurer or broker, including readings, pictures and any inaccessible sections.
Keep certificates, reports and readings in one place so the history is easy to show.
How the job changes from site to site
Schools, hospitals and care homes
In healthcare and care settings, kitchens may run from early until late. Testing shows if the cleaning interval keeps pace.
Canopy and plenum
Clean-looking filters do not mean a clean plenum. That’s why we test behind them.
