TR19 Inspection in Watford Heath
Our technicians work in Watford Heath on TR19 inspections and grease testing. Out-of-hours visits, a fixed quote and a written report with photos as standard.
- Missing TR19 certificates or history
- Insurance renewals needing proof of TR19 cleaning
- Extracts that have never been grease tested
How we handle TR19 inspection in Watford Heath
BESA sets minimum cleaning intervals by daily use: every 3 months for heavy use of 12 to 16 hours a day, every 6 months for moderate use of 6 to 12 hours, and every 12 months for light use of 2 to 6 hours. Those are minimums, and grease readings help set the real interval. The work covers post-clean checks, deposit thickness tests and wet film thickness tests, and people most often call us about kitchens whose menu or hours have changed and insurance renewals needing proof of TR19 cleaning.
In a smaller place like Watford Heath, many kitchens sit in older buildings or later extensions, where the duct may cross a roof void or climb an outside wall. Long horizontal runs like that hold grease and need access panels to reach.
For insurers and inspectors, the record counts. So every job comes with a written report and photos, and grease extract cleans come with a TR19® certificate issued through the BESCA Vent Hygiene Elite portal.

When it’s something else
We will not sell you work that does not address the problem, so these are the things it won’t cover:
- Heavy deposits found on test, which still need cleaning
- Fan breakdowns, which need a repair visit
- Parts of the duct nobody can reach yet
If you’re not sure, just call 0345 646 2711 or email us and we’ll give you a straight answer before booking.
What the work covers

What affects the quote in Watford Heath
A fixed price needs a few facts first. We check:
- How easy every part is to reach
- Travel, parking and unloading
- How many systems or sites are involved
- The condition of the system
A single site or a whole portfolio, we price it on the same basis: the work involved, the access and the timing. The price is fixed before any work starts.
What to send for a quote
To help us quote quickly, send us:
- The roof, plant room or outside wall the system runs to
- Any symptoms, from odd noises to smells or leaks
- Your last certificate, test record or report
- A few general shots of the system
Photos are the quickest way to a quote: wide shots of the system, close-ups of anything that worries you and how we’d get to it. Add the site type and your opening hours, and many jobs can be priced from that alone.
Watford Heath: your questions answered
Can you come to Watford Heath after we close?
Yes, we can come after you close and finish before you open. That way a site in Watford Heath doesn’t have to lose a day’s trading. When you phone us on 0345 646 2711 or send us an email, mention when the site is quiet.
Can you clean school kitchen extracts in Watford Heath during the holidays?
Yes, holiday work suits schools best. There are about 29 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of Watford Heath. Booking early in the term gives the best choice of holiday dates.
What information do you need?
The site address, the type of premises and your opening hours, along with a few pictures and any previous report.
How much does TR19 inspection cost?
The cost depends on the size of the system, its condition, access and timing. Ask us for a fixed quote, normally ready within one working day.
Which kinds of sites do you work on?
Any site with a kitchen or a ventilation system to look after, from a single café to a large school. We work with hotels, schools, care homes, offices, retail and leisure sites.
Why survey before a clean?
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. Missing access panels are noted so they can be sorted first.
What about areas you cannot get to?
Anything we can’t reach goes on the report, with a note of where it is, and we explain what access is needed, for example new access panels.
How do you measure grease in a kitchen extract?
WFTT and DTT are the two methods for measuring grease thickness, in microns. We take readings at set points from canopy to fan.
When to call us in Watford Heath
Records can go missing when a business changes hands or contractors. Without them, nobody knows how much grease is in the system or when it was last cleaned.
Most sites get in touch after spotting something like this:
- Missing TR19 certificates or history
- Post-clean verification after another contractor’s clean
- Extracts that have never been grease tested
- Heavy grease suspected in the plenum or ducts
Term dates shape school work: for a school like Bromet Primary School, an extract clean fits neatly into a half-term or summer break.
Questions to ask before booking
- How areas they can’t reach will be recorded
- Whether the quote shows VAT
- How they set the interval to the next visit
- Exactly which parts of the system are covered
Leave it or put it right?
Skipping grease testing leaves the cleaning interval to guesswork. If grease reaches 500 microns anywhere, TR19® Grease calls for immediate spot cleaning, which you won’t know without measuring. Light use slows the build-up but does not stop it.
Every site is different, so each one gets its own fixed quote. The size of the job, how we reach it, its condition and the working hours all play a part.
Why us?
- We’re fully insured
- One number for every site across the South East and London
- In business since 2009
- Accredited under CHAS and SafeContractor, with ISO 9001

Kitchen extracts in Watford Heath
Food Standards Agency data counts about 119 restaurants, cafés and works canteens and about 37 sandwich bars and takeaways in Watford Heath and the streets around it, up to about 1.5 miles out. A WFTT or DTT reading tells each of those kitchens whether its grease is staying under the 200-micron mean. Kitchens in Watford Heath get their food hygiene inspections from Watford council. They look at how clean the premises and equipment are, and the kitchen extract is part of that. Keeping each certificate and photo report on file helps show the extract is looked after. The fire and rescue service for Watford Heath is 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.
Healthcare kitchens, like those at hospitals such as Watford General Hospital (about 1.1 miles north-west), often cook for long hours, which puts them in BESA’s heavier-use bands. If you run a café or takeaway near Bushey station, early starts and late finishes leave little time to clean, so overnight extract cleaning suits.

Between visits
To keep the system working properly between visits:
- Tell us if menus or opening hours change
- Do not box in or cover duct access panels
- Never cook with filters missing
- Diary the next grease test and clean
Each report suggests the next clean and the next test, from the measured grease and the kitchen’s hours.
Regular grease readings keep the cleaning interval honest. It shows if build-up is speeding up.
