How we handle TR19 inspection in Dancers Hill
Grease thickness testing tells you how much grease is sitting in the canopy, ducts and fan. We use the Wet Film Thickness Test (WFTT) or the Deposit Thickness Test (DTT), taking readings at set points. From the numbers, you can see whether cleaning is due. Typical jobs include sites with gaps in their extract records and missing access panels found on survey, across deposit thickness tests, access surveys and insurer audits.
Kitchens in Dancers Hill, like many across London, can share a building with flats or offices, with the duct running up through shared risers. Grease in a duct like that is a fire risk to the whole building, not just the kitchen, which is why keeping it clean to TR19® matters.
The report is your system’s health record: dated, with pictures, and showing what was done. For TR19® Grease cleans, the certificate comes through the BESCA Vent Hygiene Elite portal and sits alongside the report.

How the visit works
A visit follows the same order every time: sheeting and protection first, make the system safe, carry out the TR19 inspection, tidy up and hand over the paperwork. The visit itself takes a morning or less for one kitchen, more where there are several systems. If your building in Dancers Hill has sign-in rules, permits or key holders, mention them when you book.
- We go through any past certificates and reports.
- We follow the extract from canopy to discharge.
- We note where access panels are and where more are needed.
- Grease readings are taken and pictures recorded.
- You get a report and a fixed quote for the clean.
How to prepare
- Have your last certificate or report to hand
- Mention any locked doors, roof access or ceiling voids
- Plan for cooking equipment or plant to be off before we arrive
Ask for a quote
Photos are the quickest way to a quote: the system from a couple of angles, plus any access panels or hatches. Tell us what kind of site it is and when it’s open, and we can price many jobs without a visit.

What the work involves, part by part
Vertical risers
Risers in multi-storey buildings can pass through other areas, so we arrange access ahead of time.
Canopy and plenum
We look over the canopy, inside and out, with readings where grease collects.
Leave it or put it right?
Finding a hotspot early means a targeted spot clean rather than a bigger problem later. Left alone, grease keeps building between cleans. In Dancers Hill, as across London, ductwork often passes through shared risers and other people’s space.
One small site or a whole estate, we price it on the same basis: the work involved, the access and the timing. The price is fixed before work begins.

What TR19 inspection looks like in Dancers Hill
Food Standards Agency records list about 18 restaurants, cafés and works canteens and about 4 sandwich bars and takeaways across Dancers Hill and its immediate surroundings (about a mile and a half). Kitchens like these cook for very different hours, and grease testing shows which extracts need cleaning soonest. London jobs typically start after the last service, with loading and roof access agreed with the building first. Food hygiene inspections in Dancers Hill are the job of Hertsmere council’s environmental health team. Extraction counts as kitchen equipment, so its condition can come up on the day. Before-and-after pictures from each clean are a simple way to show the extract is in hand.
A hospital like Barnet General Hospital, about 2.1 miles south, is the kind of site where a kitchen may cook for patients, staff and visitors all day. Wyllyotts Manor, about 1.5 miles north-east, is one of the historic houses near Dancers Hill; if you run event catering at a venue like that, cleans can be booked between functions. Bursars and site managers at schools such as Dame Alice Owen's School tend to book extract cleaning for when the kitchen is empty.

When it’s something else
An honest diagnosis matters more to us than a booking, so here’s what TR19 inspection won’t do:
- Fan breakdowns, which need a repair visit
- Heavy deposits found on test, which still need cleaning
- The legal duty, which stays with the responsible person
Not sure which it is? You can call 0345 646 2711 or send us an email and we’ll tell you honestly.

Landlords, agents and facilities managers
Running several sites is easier with one contractor. We cover South East England and London, so visits at different addresses can be planned together and kept to a regular schedule.
If you look after several sites, we can schedule visits across all of them on one quote. Each site gets its own report and pictures, so each one has its own record.
In-house cleaning or a specialist?
When your team notices a problem between visits, like drips, unusual noise, smells or damaged filters, it’s best reported rather than tackled in-house. We can diagnose it and quote.
In-house cleaning and specialist cleaning do different jobs. A daily filter wipe and a weekly filter wash keep grease down at the front of the system, but they don’t reach the grease that builds up further in. Reaching it takes a specialist with the right equipment.
Looking after it afterwards
After the visit, a few habits help the work last:
- Look out for grease drips round the canopy edge
- Flag changes in how much frying the kitchen does
- Clean grease off the canopy between professional cleans
- Have the latest report ready for insurance renewals
Keep the verification report next to the certificate it relates to. Together they show the system was cleaned and checked.
Revisit the cleaning interval whenever the menu or hours change. Fresh readings show whether it needs to change.
FAQs for Dancers Hill
Who would carry out a food hygiene inspection at a kitchen in Dancers Hill?
That’s Hertsmere council, whose environmental health officers carry out food hygiene inspections in Dancers Hill. An officer may look up into the canopy, so clean filters on the day and a recent certificate on file both help.
What do you need to know about parking in Dancers Hill?
Parking and loading in London need planning, so tell us about bays, permits and building rules when you book. Much of our London work is done overnight, which helps.
Do you check other contractors’ cleans?
After a clean, we take new readings and pictures to show how the system was left. It can follow our own cleans or another contractor’s.
Do you look at the system first?
Yes. Every job is surveyed first, from your pictures and details, or with a visit where needed. A fixed quote follows.
Will you produce a report for our insurer?
Yes, for kitchens across the South East and London. Tell us what your insurer has asked for and we’ll set the report out to match.
What happens to the waste?
It leaves the site with us when we go. During the work, it’s contained so the area stays clean.

CHAS, SafeContractor, ISO 9001 and BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease. We have been trading since 2009 and we are fully insured.
