TR19 inspection in Hay Street, done properly
Under TR19® Grease, the mean grease thickness should stay at or below 200 microns between cleans, and 500 microns or more at any point needs immediate spot cleaning. Grease testing shows which side of those lines you’re on. Typical jobs include insurers asking for TR19 evidence and checking the result of a recent clean, on wet film thickness tests, post-clean checks and access surveys.
Somewhere as small as Hay Street, commercial kitchens are few: perhaps a pub, a school or care home kitchen, or a hall used for events. Every one of them still needs its extract kept clear of grease.
Nothing is signed off by word of mouth: a written report, dated and illustrated with photos, plus a certificate through the BESCA Vent Hygiene Elite portal when the work is a TR19® Grease clean. It shows what was done and what, if anything, couldn’t be reached.

In-house cleaning or a specialist?
Logging matters as much as cleaning. A simple log of filter washes, wipe-downs and checks helps show that the system is managed between specialist visits, alongside our reports.
Staff cleaning and specialist work aren’t the same thing. Wiping filters daily and washing them weekly keeps the visible parts in order, but grease that has passed the filters is out of reach. That part needs specialist access and equipment.
What we do, step by step
Each visit runs to the same pattern: protect the area, make the system safe, carry out the TR19 inspection, clear away and leave you the report. On site, the work takes a morning or less for one kitchen, more where there are several systems. Visits to a village like Hay Street are booked in advance, at a time that suits whoever runs the site.
- After the clean, we arrange a time to check the system.
- The same access points are opened up.
- We repeat the WFTT or DTT readings.
- We photograph each area to record how it was left.
- The results are reported, with anything missed flagged.
Preparing for the visit
- Let us know how we reach the system, including roofs, risers and plant rooms
- Mention any sign-in, permit or induction we need
- Make sure equipment near the work can be switched off and left to cool
Getting a quote
Photos are enough for some jobs, while others need a look on site. Larger sites, and anything hidden behind walls, ceilings or floors, are normally surveyed first. Either way, the quote is fixed before any work is booked.

What else we do in Hay Street
For landlords and multi-site operators
For anyone managing more than one site, we can schedule visits across all of them on one quote. Every building has its own written report, so records stay tidy.
The Fire Safety Order 2005 puts the duty to manage fire risk on the responsible person, and that can be the employer, the owner, a landlord, a facilities manager or a managing agent. With shared responsibility, good records help everyone.
Common problems we fix in Hay Street
Looking at a canopy tells you little about what’s in the duct. A system can look clean at the filters and be heavily coated further in, which is why readings matter.
These are the problems we see most often:
- Heavy grease suspected in the plenum or ducts
- Missing TR19 certificates or history
- Kitchens whose menu or hours have changed
- Surveys needed before quoting a full clean
Historic houses near Hay Street, such as Much Hadham Palace about 4.7 miles south-east, are a reminder that older buildings with event kitchens can have long, awkward duct routes.
What your quote should include
- What hours they’ll be on site
- If the quote is a fixed price or an estimate
- What insurance they carry
- How they set the interval to the next visit
Aftercare tips
Here’s the after-treatment advice, short and simple:
- Diary the next grease test and clean
- Have the latest report ready for insurance renewals
- Never cook with filters missing
- Mention new equipment or longer hours at the next test
The report recommends when the system should next be cleaned and tested, based on the readings and how the kitchen is used.
Close the access gaps found during inspection, so grease isn’t left building in hidden parts.
What affects the quote in Hay Street
Your quote is based on your site. We consider:
- How big the system is
- Any permits to work or inductions
- The number of sites or systems
- A single visit or a regular plan
Whatever the type of site, the quote works the same way: the size of the job, access, condition and working hours. Ask for a fixed quote and we’ll explain each part.
Asking for a quote
What to send for a quote:
- Any access panels or hatches you can see
- Your last certificate, test record or report
- Where the site is and what kind of site it is
- Where the plant sits or the system leaves the building, such as a roof or outside wall
If you need TR19 inspection in Hay Street, ring 0345 646 2711 or send us an email. Tell us what kind of premises it is and when it’s open, plus photos or the previous report if they’re to hand. A fixed quote normally follows within one working day.
When something else is needed
We’d rather tell you now than book work that won’t help, so these are the things it will not cover:
- The grease itself, which needs a full or spot clean
- Design faults in the extract system
- Hidden runs that need access panels first
If you are not sure, just ring 0345 646 2711, or send details by email and we’ll give you a straight answer before booking.

Your questions about TR19 inspection in Hay Street
Will you come out to Hay Street?
Yes, Hay Street is part of our area, however small the site. Just mention lanes, gates or anything else about the site when you book.
Who enforces fire safety at workplaces in Hay Street?
It’s Hertfordshire Fire and Rescue Service, which covers Hay Street. It’s worth keeping your fire risk assessment, TR19® certificates and photo reports together, ready to show.
How often should a kitchen extract be inspected?
We suggest a next test date in every report, taking the readings and the kitchen’s hours into account. A risk assessment based on measured grease should set the interval.
Can you verify a clean after it’s been done?
Verification means repeat readings and photos once the clean is done. Any areas that weren’t cleaned properly are flagged.
What types of premises do you cover?
Commercial premises of every kind: kitchens, offices, schools, healthcare, retail, leisure and food production. We fit the work around how the site operates.
Can we book visits on a schedule?
Yes. We run scheduled maintenance contracts, set at the interval the system needs. The report from each visit recommends the next date.
What’s TR19?
It’s the industry benchmark for cleaning ventilation and kitchen extract systems, written by BESA. It covers how systems are inspected, cleaned and checked, and it takes a risk-based approach.
Can the work be done while we’re closed?
Yes, and that’s how we prefer to work. The visit is timed for when the area isn’t in use, whether that is late evening, overnight or a weekend.
Kitchen extracts in Hay Street
The Food Standards Agency lists about 3 pubs and bars as registered food businesses in and around Hay Street, up to about a mile and a half out. Wherever they cook, the canopy, duct and fan collect grease just as a restaurant’s do. It’s East Hertfordshire council that sends environmental health officers to food businesses in Hay Street. A greasy canopy or dripping filters are the sort of thing an inspection can pick up. A dated certificate in the maintenance file answers the question before it’s asked. Hay Street 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.
If you run a church or community hall kitchen, near Parish Church of St Mary the Virgin or elsewhere in Hay Street, its extract still collects grease from every lunch and event. Bursars and site managers at schools such as Jenyns First School and Nursery tend to book extract cleaning for when the kitchen is empty.
