How we price TR19 inspection
Every site gets its own quote. These are the things that affect it:
- The scale of the work
- A single visit or a regular plan
- The condition of the system
- The times the site is available
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 we need to know
When you contact us, it’s useful to have:
- Your opening hours and when the area is out of use
- A few general shots of the system
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
- Any previous report or certificate
Some systems can be priced from photos; others need a survey. Larger sites, and anything hidden behind walls, ceilings or floors, are normally surveyed first. Either way, you get a fixed price before work begins.
About our TR19 inspection in Shenley
If you’ve taken over a kitchen in Shenley and do not know when the extract was last cleaned, an inspection is the place to start. We survey the system, measure the grease and tell you what needs doing, so the next step is based on facts. If you have confirming a clean reached the whole system and pre-clean surveys before a first TR19 clean, we can help.
Kitchens around a place like Shenley are often in older buildings or single-storey extensions, with the duct running through a roof space or up an outside wall. Flat runs collect grease and need proper access to clean.
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, with full insurance on top.

How it works
The visit has three parts: getting the area ready, doing the work and signing it off. Getting ready means protecting surfaces and switching off what needs to be off, and the sign-off is a written report with pictures. Most of the time goes on the work itself, and that takes an hour or two for a single kitchen, longer for a large or complex system. Around Shenley, access is usually simpler than in a town centre, though gates and roof access are worth mentioning.
- After the clean, we arrange a time to check the system.
- The same access points are opened up.
- Grease readings are taken again at set points.
- Photos are taken to show the condition after the clean.
- The results are reported, with anything missed flagged.
Preparing for the visit
- Let us know about parking and loading
- Make sure someone can let us in and lock up afterwards
- Dig out any earlier paperwork for the system
How to get a quote
Here’s what helps us quote: the address, the type of site and when it’s open, photos of the system and the last certificate or report, if there is one. Then call us on 0345 646 2711, or send details by email.

Shenley: your questions answered
Can school kitchens in Shenley be cleaned in the holidays?
Yes, and it’s the easiest time to do it. With about 3 schools and colleges on the FSA’s register within roughly a mile and a half of Shenley, it pays to plan holiday dates ahead. Tell us your holiday dates and we will book the visit for when the site is empty.
Will you come out to Shenley?
Yes, smaller places are covered as well as towns. Just mention lanes, gates or anything else about the site when you book.
What does a pre-clean survey involve?
We look at the system from canopy to discharge, take grease readings and check access. From it, we plan the clean and quote a fixed price.
Do you offer maintenance contracts?
Yes. Scheduled maintenance plans are part of what we do, set at the interval the system needs. The report from each visit recommends the next date.
Is a quote from photos possible?
In many cases, yes. Photos of the system and the access, plus your opening hours and last report, are often enough. Larger or hidden systems need a survey on site first.
What does TR19 inspection cost?
Every site is different, so each gets its own fixed quote. To get one, phone us on 0345 646 2711 or email us and tell us about the site and its opening hours.
How long does a TR19 inspection take?
Typically, the inspection takes around an hour or two per canopy and duct system. The size of the system and the access make the difference.
What should I send you?
Some photos and a quick description of the system, with the address and opening hours. We’ll ask for anything else we need.
In-house cleaning or a specialist?
Staff cleaning doesn’t replace a specialist visit; it supports it. Clean filters and tidy surfaces slow the build-up, but the parts you can’t see still need a specialist at the right interval.
Some jobs should never be done in-house: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease call for the right kit, training and safe access. Leave those to us.
Signs you need TR19 inspection in Shenley
Kitchens change: a new menu, longer hours or more frying can all add grease. The old cleaning schedule may not match the kitchen any more.
Look out for any of the following:
- Extracts that have never been grease tested
- Uncertainty over how often to clean
- Checking the result of a recent clean
- An insurer’s request for a TR19 audit
If you run catering at a healthcare site, such as a hospital like Shenley Hospital about under half a mile west, the extract may need cleaning more often than a part-time kitchen.
Questions to ask before booking
- Whether the quote shows VAT
- Proof of accreditation you can verify
- Proof of insurance
- Whether a survey comes first
TR19 inspection around Shenley
Food Standards Agency data counts about 22 restaurants, cafés and works canteens and about 5 takeaways and sandwich shops within about 1.5 miles of central Shenley. A WFTT or DTT reading tells each of those kitchens whether its grease is staying under the 200-micron mean. Shenley sits within the area of 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. Environmental health officers from Hertsmere council inspect food businesses in Shenley. 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.
Wyllyotts Manor, about 4.1 miles east, is one of the historic houses near Shenley; if you run event catering at a venue like that, cleans can be booked between functions. Bursars and site managers at schools such as Shenley Primary School tend to book extract cleaning for when the kitchen is empty.

Honest limits
It’s worth knowing the limits before booking:
- Installation problems, which fall under design guidance such as DW172
- Removing the grease, which is a separate clean
- Mechanical faults in the extract
Not sure which it is? You can ring 0345 646 2711 or send us an email and we will tell you honestly.
What the work covers
- Post-clean checks
- Access surveys
- Insurer audits
- Pre-clean surveys
- Wet film thickness tests
- Deposit thickness tests
What the work involves, part by part
Extract fan and discharge
The discharge at the end of the system is checked as well, since grease reaches the very end of the system.
Horizontal duct runs
Bends and long runs can hold heavy deposits, out of sight of the kitchen.
Why act early in Shenley
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. When a site near Shenley shuts unexpectedly, the people who rely on it notice at once.
We do not list prices on the website, because the cost depends on the site in front of us. For a fixed quote, ring 0345 646 2711 or email us, and we’ll talk you through it.
