Greater London · TR19 inspections and grease testing
TR19 inspections in Cannon Hill
Our technicians work in Cannon Hill on TR19 inspections and grease testing. Out-of-hours visits, a fixed quote and a written report with photos as standard.
- Parts of the system left out of past cleans
- Heavy grease suspected in the plenum or ducts
- Checking the result of a recent clean
Different parts, different methods
Extract fan and discharge
Grease on the fan adds to wear. The inspection shows whether it needs cleaning now.
Restaurants, pubs and hotels
Kitchens that cook for long hours build up grease faster. Readings show if the cleans are frequent enough.
TR19 inspection in Cannon Hill
If you’ve taken over a kitchen in Cannon Hill and do not know when the extract was last cleaned, an inspection is the place to start. We survey the system, measure the grease and tell you what needs doing, before any cleaning is booked. Common call-outs are for confirming a clean reached the whole system and systems cleaned on a calendar with no measurements, on wet film thickness tests, insurer audits and pre-clean surveys.
In London, few kitchens can spare a day to close, so work in Cannon Hill is normally booked for the night or the early hours. Before the clean, we agree loading, parking and roof access with whoever manages the building.
The report is your system’s health record: dated, with photos, and showing what was done. For TR19® Grease cleans, the certificate comes through the BESCA Vent Hygiene Elite portal, ready for your insurer.

What we’re called out for in Cannon Hill
Grease in a duct is flammable fuel. Flames from the range can be pulled into the canopy and travel through the ducts to other parts of the building. Knowing how much there is lets you act before it becomes a hazard.
If you notice any of these, it’s worth a diagnosis:
- Pre-clean surveys before a first TR19 clean
- Kitchens whose menu or hours have changed
- Insurance renewals needing proof of TR19 cleaning
- Parts of the system left out of past cleans
Where a hall near St James Merton, or anywhere in Cannon Hill, hosts lunch clubs or events, its extract gathers grease just as a café’s does.

What affects the quote in Cannon Hill
A fixed price needs a few facts first. We check:
- Whether it’s a one-off visit or part of a schedule
- The scale of the work
- When the work can happen, such as evenings, overnight or weekends
- Site requirements such as sign-in and permits
Kitchens, offices, schools and hospitals are all priced the same way: how much there is, how we reach it, what state it’s in and when we can work. Call for a fixed quote and we’ll explain each part.
Helping us quote
The more you tell us, the more accurate the quote. When you get in touch, it helps to send:
- Close-ups of filters, grilles, hatches or access panels
- When the site is open and when it’s quiet
- Any previous report or certificate
- How we’d reach plant on a roof or in a plant room
Need a price for TR19 inspection? Please phone us on 0345 646 2711 or drop us a line and tell us about the site. We’ll explain what we’d do and send a fixed quote before you commit to anything.
For landlords and multi-site operators
Where a tenant occupies the premises but the landlord owns the building, the lease normally sets out who maintains what. We can quote either party and send the paperwork to whoever needs it.
For anyone managing more than one site, we can plan visits across the whole estate and price them together. Each site gets its own report and pictures, so records stay tidy.

Between visits
Here’s the after-treatment advice, in brief:
- Have the latest report ready for insurance renewals
- Mention new equipment or longer hours at the next test
- Keep TR19 certificates, readings and reports together
- Look out for grease drips round the canopy edge
The audit report is set out to pass straight to your insurer or broker, including readings, photos and any inaccessible sections.
Revisit the cleaning interval whenever the menu or hours change. A quick grease test answers the question.
Common questions in Cannon Hill
Which fire service covers Cannon Hill?
It’s London Fire Brigade, which covers Cannon Hill. Records of extract cleaning are a sensible thing to have ready if a fire safety officer carries out an audit.
Do you work overnight in Cannon Hill?
Yes, out-of-hours work is a big part of what we do. That way a site in Cannon Hill doesn’t have to lose a day’s trading. Your opening times are the first thing we ask for.
How long does grease testing take?
Expect it to take an hour or two for a single kitchen, longer for a large or complex system. The visit is timed so cooking isn’t disrupted.
Can you quote from photos?
In many cases, yes. With good photos, the site type and your last report, we can price many jobs. Larger or hidden systems need a survey on site first.
Do you offer emergency callouts?
Yes, day and night, every day of the year. Office hours are Monday to Friday, 8am to 6pm, with the emergency line covering every other hour.
What does a pre-clean survey involve?
We check the layout, the grease levels and the access, so the clean goes to plan. Missing access panels are noted so they can be sorted first.
What is TR19?
TR19® is the BESA specification for keeping ventilation systems clean. TR19® Grease, a standalone specification since 2019, covers grease in kitchen extract systems, and TR19® Air covers general supply and extract systems.
What about areas you can’t get to?
They’re listed in the report, never skipped quietly. The report says which parts couldn’t be reached and why, along with a quote to put access in.
Grease, kitchens and Cannon Hill
The Food Standards Agency lists about 27 pubs, bars and clubs and about 4 hotels, B&Bs and guest houses as registered food businesses within about 1.5 miles of central Cannon Hill. Wherever they cook, the canopy, duct and fan collect grease just as a restaurant’s do. London Fire Brigade covers Cannon Hill. Fire and rescue authorities enforce the Fire Safety Order in most non-domestic premises, and in a kitchen that fire risk includes the grease in the extract. London jobs usually start after the last service, with loading and roof access agreed with the building first.
For schools such as Hillcross Primary School, kitchen extract cleaning is usually booked for the holidays, when the canteen is closed. If you run a café or takeaway near South Merton station, early starts and late finishes leave little time to clean, so overnight extract cleaning suits.

How it works
We turn up at the time agreed with you, often in the evening, overnight or at the weekend so the site keeps working. Anything that needs to be off for the work is switched off and left to cool before we start, and the area around the work is covered and protected. The work itself takes an hour or two for a single kitchen, longer for a large or complex system. Most London sites can’t stop for the day, so work in Cannon Hill is normally done overnight, early in the morning or at weekends.
- First we book a time that won’t disrupt cooking.
- The system is checked from canopy to discharge.
- Grease thickness is measured at set points by WFTT or DTT.
- Each test point and any access problems are photographed.
- We send a report setting out the readings, photos and next steps.
Getting ready for the visit
- Name a contact who can let us in at the agreed time

- Plan for cooking equipment or plant to be off before we arrive
