TR19 inspection in Walkern
Not every kitchen fits neatly into a calendar. Some kitchens build up grease faster than the minimum intervals assume, and only measurement shows it. We give your risk assessment measured figures rather than guesses. If you’re dealing with insurers asking for TR19 evidence and ductwork where grease may be over the TR19 limits, we can put it right, from pre-clean surveys, wet film thickness tests and post-clean checks onwards.
Rural kitchens often have long, low duct runs through a roof space or along an outside wall, where grease settles in the flat sections. We agree access and timings in advance.
Good records are part of the job. Each visit is written up with pictures, listing what was done, anything we couldn’t reach and when the next visit is due. File it in your maintenance log so it’s ready for an insurer, fire officer or EHO.

Staff cleaning versus specialist work
A few tasks are always specialist work: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease call for the right kit, training and safe access. That’s our job.
Keep a record of what your team does. A simple log of filter washes, wipe-downs and checks helps show that the system is managed between specialist visits, alongside our reports.
TR19 inspection in Walkern: the local picture
Kitchens in Walkern get their food hygiene inspections from East Hertfordshire council. They look at how clean the premises and equipment are, and the kitchen extract is part of that. Our report lists what was cleaned and when, which is useful to have ready. Walkern, about 29 miles from central London, is within our usual area. We work evenings, overnight and at weekends, so the visit fits around the site.
Healthcare kitchens, like those at hospitals such as Lister Hospital (about 3.6 miles west), often cook for long hours, which puts them in BESA’s heavier-use bands. For schools such as Walkern Primary School, kitchen extract cleaning is normally booked for the holidays, when the canteen is closed.
Walkern is about 2 miles east of Stevenage, in Hertfordshire. We carry out TR19 inspection for businesses, landlords and public buildings in Walkern and the rest of Hertfordshire. Our Hertfordshire coverage runs to 381 places, Walkern among them. Milton Keynes is in our area too, about 28 miles from Walkern.
TR19 inspection in SG2 follows the same survey, fixed quote and written report as everywhere else we cover.

Part by part
Restaurants, pubs and hotels
A kitchen running from breakfast to late service builds grease quickly. Readings show if the cleans are frequent enough.
Extract fan and discharge
Grease builds up on the fan blades and inside the housing. We check and test them as part of the inspection.
Looking after it afterwards
Think of this as the after-treatment advice, in brief:
- Keep canopy edges and gutters wiped down
- Keep access panels clear and unpainted
- Flag oily drips near the extract
- Share inspection reports with your insurer or broker when asked
After the inspection, we send a report showing each reading, its location and photos. File it alongside your TR19 certificates.
Revisit the cleaning interval whenever the menu or hours change. A quick grease test answers the question.
What we do, step by step
The visit has three parts: getting the area ready, doing the work and signing it off. Set-up means sheeting and making equipment safe, while signing off means the written report and pictures. The middle part takes longest, which takes anything from an hour for a small canopy and short duct to a good part of a day for a large site. Rural roads and tight entrances are worth telling us about before a visit to Walkern.
- First we book a time that will not disrupt cooking.
- We look over the canopy, plenum, ducts, fan and discharge.
- We take WFTT or DTT readings at set points along the system.
- Each test point and any access problems are photographed.
- You get a report with readings, pictures and recommendations.
Preparing for the visit
- Tell us the best time to work, such as after service or at a weekend
- Make sure equipment near the work can be switched off and left to cool
- Mention any sign-in, permit or induction we need
How to get a quote
There’s no standard price list, because no two systems are the same. Instead, we look at your site first, from photos or a survey, then send a fixed quote. To get going, call us on 0345 646 2711 or email us.

How we price TR19 inspection
Every site gets its own quote. This is what makes a difference:
- Access, including roofs, risers and ceiling voids
- How big the system is
- Site requirements such as sign-in and permits
- 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.
Helping us quote
When you contact us, it’s useful to have:
- The site address and the type of premises
- Photos showing the whole system and its surroundings
- Any symptoms, from odd noises to smells or leaks
- Detail shots of panels, filters and grilles
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, you get a fixed price before work begins.
Common questions in Walkern
Can you clean school kitchen extracts in Walkern during the holidays?
Yes, and it’s the easiest time to do it. Food Standards Agency records list about 2 schools, colleges and universities with registered kitchens within about a mile and a half of Walkern. Just ring 0345 646 2711 or drop us a line with your term dates and we will plan around them.
Do you cover smaller places like Walkern?
Yes, Walkern is part of our area, however small the site. Let us know about access, parking and anything unusual about getting there when you book.
Do you offer maintenance contracts?
Yes. Tell us what you have and how it’s used and we’ll propose a schedule with a fixed quote.
What happens if you can’t reach some of it?
They’re listed in the report, never skipped quietly. You’ll know exactly which parts weren’t reached and why, and we can quote to improve the access.
Can the work be done while we’re closed?
Yes, and that’s how we prefer to work. We book the visit for when the area is out of use, whether that’s late evening, overnight or a weekend.
Do you survey before quoting?
Yes, every time. Diagnosis comes before treatment: the survey tells us what the system needs and how to reach it and the fixed quote is built on it.
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. We fit the work around how the site operates.
Which accreditations do you hold?
Our accreditations are CHAS, SafeContractor and ISO 9001, and we are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. The Vent Hygiene Elite scheme is run by BESCA and audited independently.
What happens if it’s left?
After an incident, an insurer can ask to see proof of TR19 cleaning and inspection. Without them, a claim can be reduced or refused. An up-to-date inspection report is a good place to start. In a place like Walkern, ductwork and fans are easy to forget until something goes wrong.
Leaving it longer rarely makes the work cheaper. Build-up, wear and faults tend to get worse, not better, and a neglected system can mean more work. If you’re unsure, call 0345 646 2711 or send us an email for straight advice and a fixed quote.

Common problems we fix in Walkern
Looking at a canopy tells you little about what’s in the duct. Clean filters can hide a heavy layer behind them, so readings are the reliable guide.
Any of these means the system needs a check-up:
- Ductwork where grease may be over the TR19 limits
- Systems cleaned on a calendar with no measurements
- Parts of the system left out of past cleans
- Kitchens taken over with no cleaning records
Aston Bury, about 2.9 miles south, is one of the historic houses near Walkern; if you run event catering at a venue like that, cleans can be booked between functions.
