Greater London · TR19 inspections and grease testing
Oakleigh Park TR19 inspection
TR19 inspections, grease thickness testing, pre-clean surveys and post-clean verification for commercial sites in Oakleigh Park and across Greater London. CHAS, SafeContractor and ISO 9001, and fully insured.
- Systems that need surveying before cleaning
- Sections of duct that can’t be reached
- Missing TR19 certificates or history
Why deal with it now?
Post-clean verification shows whether the system was left the way the certificate says, while there’s still time to put anything right. Leaving it on a busy London site only adds to the work.
When the work has to happen, how we reach it and how big the site is all affect the cost. We take each of them into account and give you a fixed price before we start.
Why book with us
- CHAS, SafeContractor and ISO 9001
- One number for every site across the South East and London
- Fixed quotes from a survey or photos
- A written report with photos after each visit

TR19 inspection in Oakleigh Park, done properly
Many insurers ask for proof that kitchen extract systems are cleaned and inspected to TR19®. Missing records can lead to a claim being reduced or refused. A TR19 audit sets out the system’s condition, with readings and photos, for sites in Oakleigh Park and the rest of Greater London. The work covers pre-clean surveys, post-clean checks and wet film thickness tests, and common reasons people get in touch are extracts that may be over the 200 micron mean and missing TR19 certificates or history.
Across London, many commercial kitchens are squeezed into basements and narrow back-of-house spaces, and the duct may run up through several floors before it discharges at the roof. For a kitchen in Oakleigh Park, that normally means a longer system to clean and more access panels to plan around.
Duct Doctor has been trading since 2009, as a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we are fully insured.

What a clean will not put right
A few issues sit outside what this work can do:
- The legal duty, which stays with the responsible person
- The grease itself, which needs a full or spot clean
- Design faults in the extract system
If in doubt, call us on 0345 646 2711 or email us and we will say what we think before you book.

What TR19 inspection looks like in Oakleigh Park
Look up Oakleigh Park on the FSA’s food hygiene register and you’ll find about 139 restaurants, cafés and canteens and about 52 takeaways in and around Oakleigh Park, up to about a mile and a half out. A WFTT or DTT reading tells each of those kitchens whether its grease is staying under the 200-micron mean. Kitchens in Oakleigh Park get their food hygiene inspections from Barnet council. Extraction counts as kitchen equipment, so its condition can come up on the day. Our report lists what was cleaned and when, which is useful to have ready. Night work suits London kitchens, and roads and loading bays tend to be quieter too.
Volunteers running a hall kitchen near Church of St John, or anywhere in Oakleigh Park, may not know when the extract was last cleaned, and a grease test settles it. Term dates shape school work: for a school like Queenswell Infant & Nursery School, an extract clean fits neatly into a half-term or summer break.

What happens on the day
Our technicians bring everything the work needs, including protection sheets, the right tools and access kit. All we need from you is clear access and the right equipment switched off. On site, the work takes anything from an hour for a small canopy and short duct to a good part of a day for a large site. In a London area like Oakleigh Park, parking, loading and building access are planned before the day of the work.
- 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.
- Grease readings are taken and pictures recorded.
- We report back with readings and a fixed quote.
Getting ready for the visit
- Find the previous report, if there is one
- Plan for cooking equipment or plant to be off before we arrive
- Make sure someone can let us in and lock up afterwards

Your questions about TR19 inspection in Oakleigh Park
Which fire and rescue service is responsible for Oakleigh Park?
Oakleigh Park is in the area of London Fire Brigade. If a fire safety officer visits a commercial kitchen, they may ask about the fire risk assessment and how the extract is kept clean.
Can you clean school kitchen extracts in Oakleigh Park during the holidays?
Yes, and it’s the easiest time to do it. The FSA’s register shows about 47 schools and colleges with food registrations within roughly a mile and a half of Oakleigh Park. Just call 0345 646 2711 or use the quote form with your term dates and we will plan around them.
Can you verify a clean after it’s been done?
A post-clean check records grease readings and photos after the work, for our cleans and other firms’ alike.
How do you keep the site clean during the work?
Protection goes down first: floor sheeting and covers over nearby surfaces and equipment. We tidy up and take our waste away before we leave.
What happens if you can’t reach some of it?
They’re marked on the report. Often the fix is extra access, such as new panels in ductwork, and we can fit those.
Where does the waste go?
We contain it and take it with us. We collect grease, debris and waste water as we go, so it doesn’t spread.
Is there a survey before the work?
Yes. Every job is surveyed first, either from photos and details you send or on a site visit. A fixed quote follows.
How much notice should we give?
Book as early as you can for planned work, especially if the next clean or test is due soon. For emergencies, we take calls 24/7.
Signs you need TR19 inspection in Oakleigh Park
As hot, greasy air travels up the duct, it cools and leaves a film behind. It often collects where nobody can see it: the plenum, bends and horizontal runs.
What we’re most often called out for:
- Post-clean verification after another contractor’s clean
- Systems cleaned on a calendar with no measurements
- An insurer’s request for a TR19 audit
- Missing access panels found on survey
If you run a café or takeaway near Oakleigh Park station, early starts and late finishes leave little time to clean, so overnight extract cleaning suits.

How the job changes from site to site
Extract fan and discharge
The discharge at the end of the system is checked as well, as grease can build up there too.
Schools, hospitals and care homes
Inspections are planned around mealtimes and holidays so meals aren’t affected.
What affects the quote in Oakleigh Park
A fixed price needs a few facts first. We check:
- Whether it’s a one-off visit or part of a schedule
- The number of sites or systems
- Access, including roofs, risers and ceiling voids
- The size of the system
Several systems or sites on one quote often makes better use of the time. Tell us about everything you’d like looked at and we’ll price it together.
What to send for a quote
The more you tell us, the more accurate the quote. When you get in touch, it helps to send:
- Problems your staff have spotted
- Close-ups of filters, grilles, hatches or access panels
- The paperwork from the last visit, if you have it
- Wide pictures of the system and the area around it
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.
In-house cleaning or a specialist?
Keep a record of what your team does. A dated log of in-house cleaning and checks helps show that the system is managed between specialist visits, next to our reports.
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.
