How we handle TR19 inspection in South Mimms
A fixed schedule doesn’t always match how a kitchen really cooks. Some kitchens build up grease faster than the minimum intervals assume, and only measurement shows it. Our readings give your risk assessment real numbers to work from. Typical jobs include kitchens taken over with no cleaning records and kitchen extract systems with no recent grease readings, on access surveys, post-clean checks and pre-clean surveys.
For a kitchen in or near South Mimms, the visit is planned around opening hours and the journey, and the clean itself is the same full TR19® job as in any town: canopy to discharge, then a TR19® certificate and a photo report.
Accreditations are easy to claim and worth checking. Ours are BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease, plus CHAS, SafeContractor and ISO 9001, and we’re fully insured.

South Mimms: your questions answered
Is South Mimms within the area you cover?
Yes, South Mimms is part of our area, however small the site. Let us know about access, parking and anything unusual about getting there when you book.
Who is the fire and rescue service for South Mimms?
That is Hertfordshire Fire and Rescue Service. TR19® is not law, but it’s the benchmark many fire officers and insurers look to when they ask how often the extract is cleaned.
Which sectors do you work in?
We work for restaurants, pubs, hotels, schools, colleges, hospitals, care homes, offices and shops, as well as food production and leisure sites.
How long does grease testing take?
It takes a couple of hours for a typical kitchen extract system. The visit is timed so cooking isn’t disrupted.
What do you need from me for a quote?
A short description and a few photos, with the address and opening hours. If we need more, we will ask.
Do you check other contractors’ cleans?
A post-clean check records grease readings and photos after the work, whoever did the clean.
What do the grease readings need to be?
The TR19® Grease figures are a mean of 200 microns or less between cleans, and immediate spot cleaning wherever a reading hits 500 microns. Our report sets your readings against both.
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.

Keeping the system healthy
A little care between visits keeps the system in better shape. We recommend:
- Don’t box in or cover duct access panels
- Mention new equipment or longer hours at the next test
- Store grease readings where your insurer can see them
- Never cook with filters missing
You get a report with the grease readings, where they were taken and pictures of each point. File it alongside your TR19 certificates.
Clean, correctly fitted filters stop more grease reaching the duct. Gaps around filters let grease get past them.
What TR19 inspection looks like in South Mimms
There are about 13 restaurants, cafés and canteens and about 4 sandwich bars and takeaways in and around South Mimms, up to about a mile and a half out, according to the Food Standards Agency’s register. Where they cook under a canopy, a grease reading is the way to tell whether the extract is due a clean. Kitchens in South Mimms get their food hygiene inspections from Hertsmere council. A greasy canopy or dripping filters are the sort of thing an inspection can pick up. Keeping each certificate and photo report on file helps show the extract is looked after. The fire and rescue service for South Mimms is Hertfordshire Fire and Rescue Service. Grease in a kitchen extract is a recognised fire risk, and the fire authority enforces the law on managing it in most commercial premises.
Volunteers running a hall kitchen near Church of St Giles, or anywhere in South Mimms, may not know when the extract was last cleaned, and a grease test settles it. If you run catering at a healthcare site, such as a hospital like Shenley Hospital about 2.7 miles west, the extract may need cleaning more often than a part-time kitchen. School kitchens, at schools like St Giles' CofE Primary School for example, are usually cleaned in the holidays so no lunches are lost.

What affects the quote in South Mimms
Your quote is based on your site. We consider:
- How big the system is
- The times the site is available
- What state the system is in
- The number of sites or systems
Leaving it longer rarely makes the work cheaper. Problems in a system tend to grow, which can make the next visit longer. If you’re not sure what’s needed, give us a ring on 0345 646 2711, or email photos and we’ll give you an honest view and a fixed quote.
What we need to know
There’s no need for technical detail. It helps if you can send:
- Your opening hours and when the area is out of use
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- The site address and the type of premises
- Your last certificate, test record or report
Here’s what helps us quote: where the site is, what it is and its opening hours, photos of the system and the last certificate or report, if there is one. Once you have those, call 0345 646 2711 or use the quote form.
Landlords, agents and facilities managers
Running several sites is easier with one contractor. We cover South East England and London, so visits at different addresses can be planned together and kept on a regular cycle.
When the building owner and the occupier are different, it’s worth checking the lease for who maintains the systems. We are happy to deal with either side and send the paperwork to whoever needs it.
What we do, step by step
The visit has three parts: getting the area ready, doing the work and signing it off. Set-up means sheeting and making equipment safe, and the sign-off is a written report with photos. The middle part takes longest, and that takes an hour or two for a single kitchen, longer for a large or complex system. Rural roads and tight entrances are worth telling us about before a visit to South Mimms.
- Post-clean verification is booked once the clean is done.
- We open the access points used on the clean.
- Grease readings are taken again at set points.
- We photograph each area to record how it was left.
- We report the findings and flag any areas that need more work.
How to prepare
- Mention any locked doors, roof access or ceiling voids
- Make sure someone can let us in and lock up afterwards
- Mention any sign-in, permit or induction we need

Related advice
What happens if it’s left?
If there’s a fire or a claim, your insurer may ask for TR19 records. Missing records can put a claim at risk. An up-to-date inspection report is a good place to start. Rural sites cannot always move to another kitchen or room when something fails.
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 make a difference.

What a clean will not put right
We’d rather tell you now than book work that won’t help, so these are the things it won’t cover:
- Fan breakdowns, which need a repair visit
- The grease itself, which needs a full or spot clean
- Sections with no access, until panels are fitted
If you are not sure, just phone us on 0345 646 2711 or drop us a line and we will give you a straight answer.
Where we work
- Deposit thickness tests
- Wet film thickness tests

What your team can do, and what needs us
In-house cleaning and specialist cleaning do different jobs. A daily filter wipe and a weekly filter wash keep grease down at the front of the system, but grease that has passed the filters is out of reach. Reaching it takes a specialist with the right equipment.
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.
