About our TR19 inspection in Shephall
BESA sets minimum cleaning intervals by daily use: heavy use (12 to 16 hours a day) every 3 months, moderate use (6 to 12 hours) every 6 months and light use (2 to 6 hours) every 12 months. Grease testing shows whether your kitchen needs cleaning more often than that. Common call-outs are for sections of duct that can’t be reached and missing TR19 certificates or history, across access surveys, wet film thickness tests and post-clean checks.
In a smaller place like Shephall, many kitchens sit in older buildings or later extensions, with the duct running through a roof space or up an outside wall. Long horizontal runs like that hold grease and need access panels to reach.
Our accreditations include CHAS, SafeContractor and ISO 9001, and we are fully insured. We’re also a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we’ve been trading since 2009.

Multi-site and managed buildings
Whether it’s one building or many, you get the same standard: a survey first, a fixed quote, the work timed around the site and a report with photos.
We work for landlords, managing agents and facilities managers as well as the people running the site. Shared systems, like a riser serving several units, need a clear agreement on who books the work, and we’re happy to quote for all of it.
Aftercare tips
A little care between visits keeps the system in better shape. Our advice:
- Tell us if menus or opening hours change
- Look out for grease drips round the canopy edge
- Book the next test on the date in the report
- Keep TR19 certificates, readings and reports together
Each report suggests the next clean and the next test, based on the readings and how the kitchen is used.
Revisit the cleaning interval whenever the menu or hours change. A quick grease test answers the question.
Common questions in Shephall
Do you work at weekends in Shephall?
Yes, evening, overnight and weekend work is normal for us. Your customers, staff or residents in Shephall needn’t be disturbed. When you call 0345 646 2711 or drop us a line, mention when the site is quiet.
Do you do school kitchen extract cleaning in Shephall in the summer holidays?
Yes. Half-terms and the summer break are the natural time for school work. Around Shephall, the Food Standards Agency lists about 28 schools and colleges with registered kitchens within a mile and a half or so. Send us your term dates when you phone us on 0345 646 2711, or send details by email, and we’ll fit the work in.
What is grease thickness testing?
The Wet Film Thickness Test (WFTT) and Deposit Thickness Test (DTT) measure how thick the grease is at a given point. Readings are taken at set points through the system.
What is post-clean verification?
Verification means repeat readings and photos once the clean is done. Any areas that weren’t cleaned properly are flagged.
What if parts of the system can’t be reached?
They’re listed in the report, never skipped quietly. The report says which parts couldn’t be reached and why, and we can quote to improve the access.
Which sectors do you work in?
All kinds of commercial and public premises: from restaurants, pubs and hotels to schools, hospitals, care homes, offices, shops and food production sites. Work is timed around how each site runs.
What happens to the waste?
Waste is contained during the work and removed when we leave, from grease and debris to used cleaning water. None of it is left on site.
Do you carry out TR19 audits for insurers?
Yes, anywhere in the area we cover. Tell us what your insurer has asked for and we’ll set the report out to match.
What your team can do, and what needs us
Day-to-day cleaning is something your team can do: wiping canopies, washing grease filters and recording it in a log. What they cannot safely do is clean inside the ductwork, the fan or the risers, which is where we come in.
Some jobs should never be done in-house: entering ducts, working on fans, testing dampers and taking grease readings need training, the right equipment and safe access. That is our job.
The process
The first job on site is protection: sheeting goes over floors and surfaces close to the work. Then we make the system safe and start. It takes around an hour or two per canopy and duct system, and the area is cleaned down before we leave. Visits to a place like Shephall are planned ahead, so we arrive with what the survey says the job needs.
- Post-clean verification is booked once the clean is done.
- The same access points are opened up.
- Grease readings are taken again at set points.
- We photograph each area to record how it was left.
- The results are reported, with anything missed flagged.
How to prepare
- Let us know when the site is closed or quiet
- Make sure equipment near the work can be switched off and left to cool
- Have your last certificate or report to hand
Ask for a quote
To help us quote: the address, the type of site and when it’s open, pictures of the system and any previous report or certificate. Then phone us on 0345 646 2711, or send details by email.

Kitchen extracts in Shephall
The FSA’s food hygiene register shows about 81 cafés, restaurants and staff canteens and about 55 takeaways in and around Shephall, up to about a mile and a half out. Each kitchen extract among them can be measured for grease to set the right cleaning interval. Food hygiene inspections in Shephall are the job of Stevenage council’s environmental health team. Extraction counts as kitchen equipment, so its condition can come up on the day. A dated certificate in the maintenance file answers the question before it’s asked. Hertfordshire Fire and Rescue Service covers Shephall. Its fire safety officers can audit commercial kitchens, and grease in the extract is part of a kitchen’s fire risk.
Volunteers running a hall kitchen near Church of Saint Mary, or anywhere in Shephall, may not know when the extract was last cleaned, and a grease test settles it. Older buildings often hide long, awkward duct runs, and if you run a kitchen at a historic venue in the area (Aston Bury is about 1.6 miles south-east), access may need planning.

What we are called out for in Shephall
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.
Most sites get in touch when they notice one of these:
- Pre-clean surveys before a first TR19 clean
- Confirming a clean reached the whole system
- Sections of duct that cannot be reached
- Kitchens whose menu or hours have changed
For schools such as Peartree Spring Primary School, kitchen extract cleaning is usually booked for the holidays, when the canteen is closed.
