TR19 inspections and grease testing in Oakwood, Greater London
TR19 inspection for commercial sites in Oakwood and across Greater London. BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease.
- Heavy grease suspected in the plenum or ducts
- Missing TR19 certificates or history
- Confirming a clean reached the whole system
What affects the quote in Oakwood
Some jobs are bigger than they look, and some smaller. The main factors:
- Whether several sites go on one quote
- Whether it’s a one-off visit or part of a schedule
- Parking and loading at the site
- How easy every part is to reach
Putting the work off seldom saves money. Problems in a system tend to grow, and a neglected system can mean more work. If you are not sure what’s needed, call us on 0345 646 2711 or drop us a line for straight advice and a fixed quote.
What we need to know
We can often survey from pictures. Try to include:
- Photos showing the whole system and its surroundings
- Your last certificate, test record or report
- How we’d reach plant on a roof or in a plant room
- The postcode and the type of business
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.
TR19 inspection in Oakwood, done properly
A grease test measures how thick the grease is inside a kitchen extract system. Readings are taken at set points using the Wet Film Thickness Test (WFTT) or the Deposit Thickness Test (DTT). The results show whether the system needs cleaning and how soon. If you’re dealing with an insurer’s request for a TR19 audit and systems cleaned on a calendar with no measurements, we can help.
London kitchens tend to trade late and open early, so work in Oakwood 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.
For insurers and inspectors, the record counts. That is why every job is written up in a report with pictures, plus a TR19® certificate through the BESCA VHE portal where the work is a TR19® Grease clean.

Common questions in Oakwood
What do you need to know about parking in Oakwood?
London parking can be tight, so details of loading bays and permits help. Much of our London work is done overnight, which helps.
Can you clean school kitchen extracts in Oakwood during the holidays?
Yes, holiday work suits schools best. Food Standards Agency records list about 34 schools, colleges and universities with registered kitchens within about a mile and a half of Oakwood. Tell us your holiday dates and we will book the visit for when the site is empty.
Can you set up regular visits?
Yes. Scheduled maintenance plans are part of what we do, set at the interval the system needs. The report from each visit recommends the next date.
What is grease thickness testing?
It’s a measurement of how much grease is coating the inside of the extract, using the Wet Film Thickness Test (WFTT) or Deposit Thickness Test (DTT). Each reading is recorded in microns.
How do you protect the area?
Protection goes down first: sheeting over floors, worktops and anything close to the work. We tidy up and take our waste away before we leave.
Is there a survey before the work?
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.
Can you inspect our extract for our insurance company?
Yes. We inspect the system and produce a report with grease readings, pictures and any inaccessible areas. You can pass it straight to your insurer or broker.
How often should grease be tested?
Each report recommends when to test and clean next, taking the readings and the kitchen’s hours into account. A risk assessment based on measured grease should set the interval.
Between visits
No system stays clean for ever, but care slows the build-up. Our tips:
- File every inspection report with your certificates
- Diary the next grease test and clean
- Tell us if menus or opening hours change
- Report grease dripping from the canopy
If any reading is 500 microns or more, the report flags it for immediate spot cleaning, and we can quote to do it.
Revisit the cleaning interval whenever the menu or hours change. A quick grease test answers the question.
How the visit 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 work begins, 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. Security desks and permits-to-work are routine in London, so let us know what your building in Oakwood needs from us.
- First we book a time that won’t disrupt cooking.
- Every part of the system is examined, end to end.
- We take WFTT or DTT readings at set points along the system.
- We photograph the test points and record any sections we cannot reach.
- You get a report with readings, pictures and recommendations.
Before we arrive
- Let us know how we reach the system, including roofs, risers and plant rooms
- Let us know when the site is closed or quiet
- Arrange a key holder or contact on site
Getting a quote
Getting a quote does not take long. Send a few details and photos, and we typically reply with a fixed quote within one working day. Where a survey is needed, we arrange a time that suits the site.
Related advice
What we’re called out for in Oakwood
You cannot judge grease thickness by eye. A system can look clean at the filters and be heavily coated further in, so readings are the reliable guide.
It’s time to book a visit if you see:
- Cleaning intervals that may not suit the kitchen
- Surveys needed before quoting a full clean
- Heavy grease suspected in the plenum or ducts
- Confirming a clean reached the whole system
Where a hall near St Thomas's Church, or anywhere in Oakwood, hosts lunch clubs or events, its extract gathers grease just as a café’s does.

Why deal with it now?
Finding a hotspot early means a targeted spot clean rather than a bigger problem later. Left alone, grease keeps building between cleans. Every month a London system goes without attention adds to what has to be done later.
Combining work into one visit or one programme often makes better use of the time. Tell us about everything you’d like looked at and we’ll price it together.

What TR19 inspection looks like in Oakwood
Food Standards Agency records list about 99 restaurants, cafés and canteens and about 30 sandwich bars and takeaways within 1.5 miles or so of the middle of Oakwood. A WFTT or DTT reading tells each of those kitchens whether its grease is staying under the 200-micron mean. It’s Enfield council that sends environmental health officers to food businesses in Oakwood. An officer looking round a kitchen will see the canopy, and grease there is hard to miss. A TR19® certificate and photo report after each clean gives you a record to show an inspector. London Fire Brigade covers Oakwood. Grease in a kitchen extract is a recognised fire risk, and the fire authority enforces the law on managing it in most commercial premises.
A hospital like Chase Farm Hospital, about 1.9 miles north-east, is the kind of site where a kitchen may cook for patients, staff and visitors all day. Older buildings often hide long, awkward duct runs, and if you run a kitchen at a historic venue in the area (Forty Hall is about 3.1 miles north-east), access may need planning.
