TR19 inspection in Marshalswick, done properly
Insurance policies often require evidence of TR19® cleaning and inspection. Without it, a claim can be refused or reduced. Our TR19 audits give sites in Marshalswick and across Hertfordshire a clear record of the system’s condition. Common call-outs are for cleaning intervals that may not suit the kitchen and ductwork where grease may be over the TR19 limits, across wet film thickness tests, pre-clean surveys and insurer audits.
Size does not change the work: a kitchen in a place like Marshalswick gets the whole system cleaned, canopy to discharge. We plan the visit around your hours, with the journey sorted in advance.
Each visit ends with a written report and photos, so there’s a dated record of the work. Kitchen extract cleaning to TR19® Grease is certificated through the BESCA Vent Hygiene Elite portal.

How the visit works
There are three stages on the day: set-up, the treatment itself and the sign-off. Getting ready means protecting surfaces and switching off what needs to be off, and the sign-off is a written report with photos. Most of the time goes on the work itself, which takes around an hour or two per canopy and duct system. For a place like Marshalswick, we load the van from the survey notes so the work can be done in one visit where possible.
- First we look at the system’s cleaning history, if there is one.
- We follow the extract from canopy to discharge.
- Access panels are located and any missing ones noted.
- We measure the grease and photograph each point.
- We report back with readings and a fixed quote.
Preparing for the visit
- Name a contact who can let us in at the agreed time
- Allow time for equipment near the work to be turned off and cool down
- Find the previous report, if there is one
Get a fixed quote
Photos are enough for some jobs, while others need a look on site. Big or complicated sites, and systems that are hard to see in photos, get a survey first. Either way, the quote is fixed before any work is booked.

What the work involves, part by part
Canopy and plenum
The plenum behind the filters can carry a lot of grease. We take readings there and photograph it on every inspection.
Horizontal duct runs
Sections without access are recorded so it can be fixed before the clean.
What happens if it’s left?
A check after cleaning shows whether the work reached every part it should have, while there’s still time to put anything right. Even a site near Marshalswick that is only busy part of the week needs its system checked on a schedule.
Several systems or sites on one quote often makes better use of the time. Mention every system or site you need covered, and you’ll get one fixed quote.

TR19 inspection around Marshalswick
Food Standards Agency data counts about 83 restaurants, cafés and canteens and about 33 takeaways within roughly a mile and a half of the centre of Marshalswick. For any of them with a canopy, measuring grease is better than guessing when to clean. Hertfordshire Fire and Rescue Service covers Marshalswick. Its fire safety officers can audit commercial kitchens, and grease in the extract is part of a kitchen’s fire risk. Environmental health officers from St Albans City council inspect food businesses in Marshalswick. The cleanliness of the kitchen and its equipment, extraction included, is part of what they check. A TR19® certificate and photo report after each clean gives you a record to show an inspector.
Bursars and site managers at schools such as St John Fisher Roman Catholic Primary School tend to book extract cleaning for when the kitchen is empty. Older buildings often hide long, awkward duct runs, and if you run a kitchen at a historic venue in the area (Batchwood Hall is about 2 miles west), access may need planning.

Marshalswick: your questions answered
Do you clean school canteen extracts around Marshalswick out of term?
Yes, and it’s the easiest time to do it. With about 18 schools and colleges on the FSA’s register within roughly a mile and a half of Marshalswick, it pays to plan holiday dates ahead. You can call 0345 646 2711, or email photos with the dates the site is empty.
Which council inspects kitchens in Marshalswick?
Kitchens in Marshalswick are inspected by St Albans City council’s environmental health officers. An officer may look up into the canopy, so clean filters on the day and a recent certificate on file both help.
Can you inspect our extract for our insurance company?
Yes, for kitchens across the South East and London. Share the insurer’s request so the report addresses it.
Where does the waste go?
We take it away when we go. While we work, it’s kept contained so the area stays clean.
Do you offer emergency callouts?
Yes. Our emergency line runs 24/7 for anything that cannot wait until a planned visit. Ring any time and tell us what’s happened.
What is grease thickness testing?
WFTT and DTT are the two methods for measuring grease thickness, in microns. Readings are taken at set points through the system.
Do you check other contractors’ cleans?
Post-clean verification is a check after a clean, with fresh grease readings and photos. It can follow our own cleans or another contractor’s.
Which sectors do you work in?
We work for restaurants, pubs, hotels, schools, colleges, hospitals, care homes, offices and shops, plus food production and leisure sites.
Managing agents and facilities teams in Marshalswick
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.
Multi-site operators often want one contractor and one number. We cover South East England and London, so visits at different addresses can be planned together and kept on a regular cycle.
Do you need TR19 inspection in Marshalswick?
TR19® is the benchmark that insurers, fire officers and EHOs refer to. It isn’t legislation; the legal duty comes from the Fire Safety Order 2005, under which the responsible person must reduce fire risk, and in a kitchen that means keeping grease under control.
The symptoms we are asked about most are:
- Sections of duct that can’t be reached
- Kitchen extract systems with no recent grease readings
- Insurance renewals needing proof of TR19 cleaning
- Surveys needed before quoting a full clean
A hospital like Hill End Hospital, about 1.1 miles south, is the kind of site where a kitchen may cook for patients, staff and visitors all day.
