Hertfordshire · TR19 inspections and grease testing
TR19 inspections and grease testing in Todd's Green, Hertfordshire
Professional TR19 inspection in and around Todd's Green, timed so the site keeps working and signed off in writing with photos.
- Kitchens taken over with no cleaning records
- Surveys needed before quoting a full clean
- Extracts that may be over the 200 micron mean
Looking after it afterwards
No system stays clean for ever, but care slows the build-up. Our tips:
- Never cook with filters missing
- Have the latest report ready for insurance renewals
- Look out for grease drips round the canopy edge
- Keep the route to access panels clear
After the inspection, we send a report showing each reading, its location and photos. File it alongside your TR19 certificates.
Test grease regularly instead of relying on the calendar. It shows if build-up is speeding up.
About our TR19 inspection in Todd's Green
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 are on. We are often asked to deal with pre-clean surveys before a first TR19 clean and heavy grease suspected in the plenum or ducts, on post-clean checks, insurer audits and deposit thickness tests.
For a kitchen in or near Todd's Green, the visit is planned around opening hours and the journey, and the clean covers the whole system, as it would anywhere: canopy to discharge, then a TR19® certificate and a photo report.
Accreditations are easy to claim and worth checking. We are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we hold CHAS, SafeContractor and ISO 9001, and we are fully insured.

FAQs for Todd's Green
Do you do school kitchen extract cleaning in Todd's Green in the summer holidays?
Yes, out-of-term visits are normal for schools. The FSA’s register shows about 10 schools and colleges with food registrations within roughly a mile and a half of Todd's Green. Booking early in the term gives the best choice of holiday dates.
Do you work at weekends in Todd's Green?
Yes, we can come after you close and finish before you open. The site is handed back ready to open. Your opening times are the first thing we ask for.
Can you set up regular visits?
Yes. Regular plans can run on 3, 6 or 12-monthly cycles, depending on what the system needs.
Where does the waste go?
Anything we remove is contained as we work and taken away with us, including grease, debris and dirty water. None of it is left on site.
How far ahead should we book?
For planned work, earlier is better, particularly if your next visit is nearly due. Emergencies are different, because our line is open 24/7.
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 types of premises do you cover?
We work for restaurants, pubs, hotels, schools, colleges, hospitals, care homes, offices and shops, as well as food production and leisure sites.
How long does a TR19 inspection take?
An inspection takes anything from an hour for a small canopy and short duct to a good part of a day for a large site. Large or multiple systems take longer, and you can give us a ring on 0345 646 2711 or use the quote form to book it in.
What your team can do, and what needs us
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.
Staff cleaning and specialist work aren’t the same thing. A daily filter wipe and a weekly filter wash keep grease down at the front of the system, but grease that has passed the filters is out of reach. Reaching it takes a specialist with the right equipment.
When something else is needed
In fairness, there are a few things this work won’t fix:
- A faulty or failing extract fan
- Heavy deposits found on test, which still need cleaning
- Installation problems, which fall under design guidance such as DW172
If in doubt, phone us on 0345 646 2711 or use the quote form and we will say what we think.
Where we work
- Post-clean checks
- Pre-clean surveys

What affects the cost of TR19 inspection
The quote reflects the site in front of us. We take into account:
- Any permits to work or inductions
- A single visit or a regular plan
- Whether we need access equipment or extra panels
- The condition of the system
Working hours, access and the scale of the site can all change the price. Each of those is built into the quote, and the price is fixed before we start.
Asking for a quote
To speed up the quote, send us:
- Detail shots of panels, filters and grilles
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- Any previous report or certificate
- Your opening hours and when the area is out of use
There’s no standard price list, because no two systems are the same. We look at your system first, from pictures or on a visit, then send a fixed quote. To get going, give us a ring on 0345 646 2711 or drop us a line.

Kitchen extracts in Todd's Green
Food Standards Agency records include about 23 bars, pubs and nightclubs and about 3 hotels and B&Bs in Todd's Green and the streets around it, up to about 1.5 miles out. Where they serve hot food, their kitchen extracts need cleaning to TR19® like any restaurant’s. Todd's Green sits within the area of Hertfordshire Fire and Rescue Service. Its fire safety officers can audit commercial kitchens, and grease in the extract is part of a kitchen’s fire risk. Kitchens in Todd's Green get their food hygiene inspections from Stevenage council. An officer looking round a kitchen will see the canopy, and grease there is hard to miss. A dated certificate in the maintenance file answers the question before it’s asked.
If you run catering at a historic house or estate in the area (Knebworth House is about 3.5 miles south), event kitchens in older buildings often have awkward duct runs that need planning. Healthcare kitchens, like those at hospitals such as Lister Hospital (about 0.6 miles east), often cook for long hours, which puts them in BESA’s heavier-use bands. If you run a church or community hall kitchen, near Church of St Mary the Virgin or elsewhere in Todd's Green, its extract still collects grease from every lunch and event.
