Hertfordshire · TR19 inspections and grease testing
TR19 Inspection in Aldenham
We cover Aldenham for TR19 inspections and grease testing. Fixed quotes, work around your opening hours and photo reports as standard.
- Kitchen extract systems with no recent grease readings
- Sections of duct that can’t be reached
- Systems that need surveying before cleaning
Between visits
So the system stays in good health:
- Keep canopy edges and gutters wiped down
- Clean or swap grease filters as often as the kitchen needs
- Flag changes in how much frying the kitchen does
- File every inspection report with your certificates
Where sections couldn’t be reached, the report says where access panels would help. Fitting them before the next clean means the whole system gets done.
Clean, correctly fitted filters stop more grease reaching the duct. Missing or damaged filters let grease straight into the plenum.
TR19 inspection in Aldenham, done properly
TR19® Grease says grease should not exceed a mean of 200 microns between cleans, while a reading of 500 microns or more anywhere calls for immediate spot cleaning. Testing is how you know where your system stands. The work covers pre-clean surveys, wet film thickness tests and insurer audits, and people most often call us about parts of the system left out of past cleans and insurance renewals needing proof of TR19 cleaning.
Somewhere as small as Aldenham, commercial kitchens are few: perhaps a pub, a school or care home kitchen, or a hall used for events. Each still has a canopy and duct that collect grease, whatever the size of the place.
It’s worth checking any contractor’s accreditations. Ours are BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease, plus CHAS, SafeContractor and ISO 9001, and we are fully insured.

What else we do in Aldenham
Landlords, agents and facilities managers
We work for landlords, managing agents and facilities managers as well as the people running the site. Shared systems, like a riser serving several units, need a clear agreement on who books the work, and we are happy to quote for all of it.
If you look after several sites, we can schedule visits across all of them on one quote. Each site gets its own report and photos, so records stay tidy.
What we do, step by step
When we arrive, we check the system against the survey or the photos you sent. 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 quick note on how to find the site and where to park makes a visit to Aldenham run smoothly.
- We agree a time when the kitchen is closed or quiet.
- The system is checked from canopy to discharge.
- Grease readings are taken at set points using WFTT or DTT.
- We photograph the test points and record any sections we can’t reach.
- You get a report with readings, photos and recommendations.
How to prepare
- Let us know about permits to work or site inductions
- Mention any parking or loading restrictions
- Arrange a key holder or contact on site

Your questions about TR19 inspection in Aldenham
Who carries out food hygiene inspections in Aldenham?
That’s Hertsmere council, whose environmental health officers carry out food hygiene inspections in Aldenham. An officer may look up into the canopy, so clean filters on the day and a recent certificate on file both help.
Do you work in villages like Aldenham?
Yes, smaller places are covered as well as towns. The journey is planned ahead, so a few details about the route help.
Can you inspect our extract for our insurance company?
Yes, for kitchens across the South East and London. Share the insurer’s request so the report addresses it.
Can one contract cover all our sites?
Yes. Tell us the addresses and what each needs and we’ll quote them together.
Do you survey before quoting?
Yes, always. We diagnose before we treat: the survey shows what needs doing and what access we need and the fixed quote is built on it.
Can you come out in an emergency?
Yes, 24/7. Our office is open from 8am to 6pm on weekdays, and the emergency line covers the rest.
Which sectors do you work in?
Commercial premises of every kind: from restaurants, pubs and hotels to schools, hospitals, care homes, offices, shops and food production sites. Work is timed around how each site runs.
What accreditations do you have?
We hold CHAS, SafeContractor and ISO 9001, and we are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. Vent Hygiene Elite is run by BESCA and independently audited.
What we are called out for in Aldenham
Grease builds up as cooking vapour cools inside the extract. The thickest layers can sit out of sight in the plenum, at bends and along flat runs.
These are the problems we see most often:
- Sections of duct that can’t be reached
- Extracts that may be over the 200 micron mean
- Systems cleaned on a calendar with no measurements
- Surveys needed before quoting a full clean
Where a hall near Church of St John the Baptist, or anywhere in Aldenham, hosts lunch clubs or events, its extract gathers grease just as a café’s does.
Before booking anyone
- What hours they’ll be on site
- Which accreditations they hold, and whether you can check them
- When the next visit should be, and why
- Whether VAT is included
Why it’s worth doing now in Aldenham
An EHO visit, an insurance renewal or a fire risk assessment is a bad time to find your extract records are thin. An inspection now gives a site in Aldenham a current picture. Somewhere as small as Aldenham, losing a kitchen or building to a fault is felt by everyone who uses it.
Putting the work off seldom saves money. Build-up, wear and faults tend to get worse, not better, which can make the next visit longer. If you are not sure what’s needed, give us a ring on 0345 646 2711 or use the quote form for straight advice and a fixed quote.

What affects the cost of TR19 inspection
The quote reflects the site in front of us. We take into account:
- Whether it’s a one-off visit or part of a schedule
- Parking and loading at the site
- What state the system is in
- When the work can happen, such as evenings, overnight or weekends
The cost depends on the size of the system, the condition it’s in and access to every part of it. You get a fixed price before work begins, so there are no surprises.
What to send for a quote
A few details help us quote accurately. When you get in touch, it helps to send:
- The postcode and the type of business
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- Any access panels or hatches you can see
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
Getting a quote doesn’t take long. Send a few details and pictures, and we typically reply with a fixed quote within one working day. If we need to see the system first, we book a survey around your hours.
What the work involves, part by part
Vertical risers
Risers can be hard to get into. The survey shows exactly what access there is.
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.
Aldenham kitchens: local notes
Food Standards Agency data counts about 17 restaurants, cafés and works canteens and about 5 takeaways within about 1.5 miles of central Aldenham. Each kitchen extract among them can be measured for grease to set the right cleaning interval. Environmental health officers from Hertsmere council inspect food businesses in Aldenham. They look at how clean the premises and equipment are, and the kitchen extract is part of that. Our report lists what was cleaned and when, which is useful to have ready. Aldenham is covered by Hertfordshire Fire and Rescue Service. Its fire safety officers can audit commercial kitchens, and grease in the extract is part of a kitchen’s fire risk.
If you run catering at a healthcare site, such as a hospital like Watford General Hospital about 2.8 miles south-west, the extract may need cleaning more often than a part-time kitchen. High Elms Manor, about 2.5 miles north-west, is one of the historic houses near Aldenham; if you run event catering at a venue like that, cleans can be booked between functions.
