TR19 inspection for kitchens and businesses in Green Street
A pre-clean survey is the diagnosis, and the clean is the treatment. Readings, photos and notes on access are gathered from end to end, so the clean can be planned properly. The work covers wet film thickness tests, insurer audits and deposit thickness tests, and common reasons people get in touch are missing TR19 certificates or history and cleaning intervals that may not suit the kitchen.
For a kitchen in or near Green Street, the visit is planned around opening hours and the journey, and the clean covers the whole system, as it would anywhere: canopy, filters, duct, fan and discharge, with a certificate and photo report at the end.
A written report with photos follows each visit, so you have a record of what was done and when. Where the work is a TR19® Grease clean, the certificate is issued through the BESCA Vent Hygiene Elite portal.

TR19 inspection around Green Street
There are about 39 restaurants, cafés and canteens and about 16 takeaways within roughly a mile and a half of the centre of Green Street, according to the Food Standards Agency’s register. A WFTT or DTT reading tells each of those kitchens whether its grease is staying under the 200-micron mean. Food hygiene inspections in Green Street are the job of Hertsmere council’s environmental health team. The cleanliness of the kitchen and its equipment, extraction included, is part of what they check. A dated certificate in the maintenance file answers the question before it’s asked. Fire safety in Green Street falls to Hertfordshire Fire and Rescue Service. In most workplaces, including commercial kitchens, it’s the fire and rescue authority that enforces the Fire Safety Order.
Term dates shape school work: for a school like Parkside Community Primary School, an extract clean fits neatly into a half-term or summer break. Kitchens that cook twelve hours or more a day, as some healthcare kitchens do, fall into BESA’s three-monthly minimum; Shenley Hospital is the nearest hospital to Green Street, about 1.6 miles north-west.

Do you need TR19 inspection in Green Street?
You can’t judge grease thickness by eye. Clean filters can hide a heavy layer behind them, which is why readings matter.
The symptoms we are asked about most are:
- Insurers asking for TR19 evidence
- Kitchen extract systems with no recent grease readings
- Checking the result of a recent clean
- Heavy grease suspected in the plenum or ducts
If you run a church or community hall kitchen, near St Michael and All Angels Church or elsewhere in Green Street, its extract still collects grease from every lunch and event.

What affects the quote in Green Street
You will get a fixed price before we start. It’s based on:
- A single visit or a regular plan
- The scale of the work
- Any permits to work or inductions
- Working hours and out-of-hours timing
The cost depends on the size of the system, the condition it’s in and how easy it is to reach. You get a fixed price before we start, so you know where you stand.
What to send for a quote
The more you tell us, the more accurate the quote. When you get in touch, it helps to send:
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
- Any previous report or certificate
- The site address and the type of premises
- Close-ups of filters, grilles, hatches or access panels
There’s no standard price list, because every site is different. We look at your system first, from pictures or on a visit, then send a fixed quote. To get going, phone us on 0345 646 2711 or send us an email.
Looking after it afterwards
Think of this as the after-treatment advice, short and simple:
- Flag oily drips near the extract
- Keep grease filters clean and fitted properly
- Clean grease off the canopy between professional cleans
- Send TR19 audit reports to your insurer on request
You get a report with the grease readings, where they were taken and photos of each point. File it alongside your TR19 certificates.
Keep all TR19 records together so the history is easy to show.
Why it’s worth doing now in Green Street
Surveying first means the clean goes to plan. Access problems are spotted in advance rather than on the night, so the clean covers the whole system. Our emergency line runs 24/7, but a planned visit to Green Street is calmer for everyone.
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. Call for a fixed quote and we’ll explain each part.
Why Green Street businesses choose us
- Every job surveyed first
- We are fully insured
- Fixed quotes, normally within one working day
- One number for every site across the South East and London
In-house cleaning or a specialist?
Your own staff can handle the daily basics: wiping down canopy surfaces, cleaning filters and keeping a simple log. Inside the ducts, risers and fan is specialist work, which is where we come in.
If your staff spot something between visits, like drips, unusual noise, smells or damaged filters, it’s best reported rather than tackled in-house. We will take a look and give you a fixed quote.
What happens on the day
There’s very little for your team to do on the day. A contact on site lets us in at the agreed time and points us to the system, and we take it from there. Afterwards, the area is left tidy and the written report follows. Somewhere as small as Green Street, the date and timings are agreed with you well before the day.
- The visit is arranged for when the kitchen isn’t busy.
- Every part of the system is examined, end to end.
- Grease thickness is measured at set points by WFTT or DTT.
- We photograph the test points and record any sections we can’t reach.
- We send a report setting out the readings, photos and next steps.
Getting ready for the visit
- Name a contact who can let us in at the agreed time
- Mention any sign-in, permit or induction we need
- Let us know about parking and loading
Ask for a quote
Quotes are quick. Call or email with a few details and you will 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
Your questions about TR19 inspection in Green Street
Can you get to a site in Green Street?
Yes, smaller places are covered as well as towns. The journey is planned ahead, so a few details about the route help.
Can you come to Green Street after we close?
Yes, out-of-hours work is a big part of what we do. The work in Green Street can fit around your hours. When you give us a ring on 0345 646 2711 or use the quote form, mention when the site is quiet.
What do the grease readings need to be?
TR19® Grease says the mean shouldn’t exceed 200 microns between cleans, and anywhere at 500 microns or more needs spot cleaning right away.
Will you produce a report for our insurer?
Yes. We inspect the system and produce a report with grease readings, pictures and any inaccessible areas. You can pass it straight to your insurer or broker.
Is TR19 cleaning the law?
No. TR19® is BESA’s specification and the industry benchmark, not legislation. The law is the Fire Safety Order 2005, under which the responsible person must manage fire risk, and TR19® is what insurers and fire officers look to.
Why survey before a clean?
We check the layout, the grease levels and the access, before anyone starts cleaning. Any access problems are flagged ahead of the clean.
Do you survey before quoting?
Yes, every time. We diagnose before we treat: the survey tells us what the system needs and how to reach it and the fixed quote is built on it.
What do you do to protect the area?
Protection goes down first: floor sheeting and covers over nearby surfaces and equipment. We tidy up and take our waste away before we leave.
What TR19 inspection cannot fix
It’s worth knowing the limits before booking:
- Removing the grease, which is a separate clean
- Mechanical faults in the extract
- Sections with no access, until panels are fitted
Not sure which it is? You can call 0345 646 2711 or send us an email and we’ll tell you honestly.
