TR19 inspection for kitchens and businesses in Letchworth Garden City
Insurance policies often require evidence of TR19® cleaning and inspection. Missing records can lead to a claim being reduced or refused. Our TR19 audits give sites in Letchworth Garden City and across Hertfordshire a clear record of the system’s condition. Common call-outs are for heavy grease suspected in the plenum or ducts and surveys needed before quoting a full clean, on post-clean checks, pre-clean surveys and access surveys.
Kitchens in towns like Letchworth Garden City are often in older buildings that were never designed for them, so duct runs can be awkward, with bends, long horizontal sections and too few access panels. Where the duct cannot be reached, new panels can be fitted, and anything left uncleaned is recorded on the report.
Every visit ends with a written report and pictures, so there’s a dated record of the work. Kitchen extract cleaning to TR19® Grease is certificated through the BESCA Vent Hygiene Elite portal.

What TR19 inspection cannot fix
Not every problem is solved by TR19 inspection, and we’d rather say so up front. It won’t put right:
- Sections with no access, until panels are fitted
- Removing the grease, which is a separate clean
- Fire safety duties beyond the extract system
If you’re not sure, just phone us on 0345 646 2711 or send us an email and we’ll give you a straight answer.
Parts of the system we cover
- Access surveys
- Deposit thickness tests
- Post-clean checks
- Pre-clean surveys
- Wet film thickness tests
- Insurer audits
What we’re called out for in Letchworth Garden City
Some parts of a system are hard to reach, and grease can be missed there clean after clean. A survey finds the sections that cannot be reached, so panels can be fitted.
What we are most often called out for:
- Surveys needed before quoting a full clean
- Kitchens whose menu or hours have changed
- Confirming a clean reached the whole system
- Extracts that have never been grease tested
Where a hall near St Michael, or anywhere in Letchworth Garden City, hosts lunch clubs or events, its extract gathers grease just as a café’s does.
Questions to ask before you book
- What’s included in the scope, part by part
- What happens if part of the system can’t be accessed
- Whether the figure could change on the day
- When they can work, and whether that’s outside your opening hours

What your team can do, and what needs us
Some jobs should never be done in-house: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease need training, the right equipment and safe access. That’s our job.
Good housekeeping makes our visits easier, not unnecessary. Clean filters and tidy surfaces slow the build-up, but hidden parts of the system still need specialist attention.
TR19 inspection in Letchworth Garden City: the local picture
Food Standards Agency records include about 17 pubs and bars and about 3 hotels and guest houses within roughly a mile and a half of the centre of Letchworth Garden City. Where they serve hot food, their kitchen extracts need cleaning to TR19® like any restaurant’s. Fire safety in Letchworth Garden City falls to 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. Environmental health officers from North Hertfordshire council inspect food businesses in Letchworth Garden City. Extraction counts as kitchen equipment, so its condition can come up on the day. Keeping each certificate and photo report on file helps show the extract is looked after.
Bursars and site managers at schools such as Pixmore Junior School tend to book extract cleaning for when the kitchen is empty. If you run catering at a healthcare site, such as a hospital like Fairfield Hospital about 1.8 miles north-west, the extract may need cleaning more often than a part-time kitchen.

Aftercare tips
A little care between visits keeps the system in better shape. Our advice:
- Keep grease filters clean and fitted properly
- Don’t box in or cover duct access panels
- File every inspection report with your certificates
- Share inspection reports with your insurer or broker when asked
Where sections couldn’t be reached, the report says where access panels would help. Fitting them before the next clean means the whole system gets done.
Close the access gaps found during inspection, so grease isn’t left building in hidden parts.

Heavy use under BESA guidance, 12 to 16 hours a day, means a clean at least every 3 months, with testing showing whether more is needed.

Your questions about TR19 inspection in Letchworth Garden City
Who inspects food businesses in Letchworth Garden City?
That is North Hertfordshire council, whose environmental health officers carry out food hygiene inspections in Letchworth Garden City. It helps to keep the extract cleaning records with your food safety paperwork, so they’re ready if asked for.
Can school kitchens in Letchworth Garden City be cleaned in the holidays?
Yes. Half-terms and the summer break are the natural time for school work. There are about 15 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of Letchworth Garden City. You can ring 0345 646 2711 or send us an email with the dates the site is empty.
Is TR19 cleaning the law?
No, not in itself. The Fire Safety Order 2005 still requires the responsible person to manage fire risk, which in a kitchen includes grease in the extract. Many insurers also expect TR19 cleaning.
What happens on a pre-clean survey?
We check the layout, the grease levels and the access, before anyone starts cleaning. Any access problems are flagged so they can be sorted first.
Are you accredited?
BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease, plus CHAS, SafeContractor and ISO 9001. We have been trading since 2009 and we’re fully insured.
Do you work in Letchworth Garden City?
Yes. Our area takes in London and the counties of South East England, Letchworth Garden City included.
Is a quote from photos possible?
Yes, if we can see what we need. Otherwise, we book a survey at a time that suits the site, then a fixed quote.
What does TR19 inspection cost?
We don’t publish prices, because the cost depends on the job: the size of the system, its condition, access and when we can work. You get a fixed price before work begins.
How the visit works
Our technicians bring everything the work needs, from protective sheeting to tools and access equipment. All we need from you is clear access and the right equipment switched off. The visit takes anything from an hour for a small canopy and short duct to a good part of a day for a large site. In a town like Letchworth Garden City, we typically work after closing or on a quiet day, so the site opens again on time.
- We agree a time when the kitchen is closed or quiet.
- We look over the canopy, plenum, ducts, fan and discharge.
- Grease readings are taken at set points using WFTT or DTT.
- Each test point and any access problems are photographed.
- We send a report setting out the readings, photos and next steps.
Preparing for the visit
- Let us know how we reach the system, including roofs, risers and plant rooms
- Tell us about site rules, permits or sign-in
- Plan for cooking equipment or plant to be off before we arrive
Getting a quote
Quoting starts with a diagnosis, from your pictures and details or, where that is not enough, a survey on site. After that, you get a fixed price for the work, before we start.
Advice
Multi-site and managed buildings
Managing agents often deal with us directly. Tell us the site, the work and the access arrangements and we’ll come back with a fixed quote.
Landlords, managing agents and facilities managers book us, not only the businesses that use the systems. Shared systems, like a riser serving several units, need a clear agreement on who books the work, and we can quote for the whole system.
