TR19 inspection in Harrow Weald
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 pictures, for sites in Harrow Weald and the rest of Greater London. Typical jobs include systems that need surveying before cleaning and extracts that may be over the 200 micron mean, across deposit thickness tests, access surveys and pre-clean surveys.
London kitchens are often tucked into basements or the back of a building, and the duct may run up through several floors before it discharges at the roof. For a kitchen in Harrow Weald, that typically means a longer system to clean and more access panels to plan around.
Our accreditations include CHAS, SafeContractor and ISO 9001, and we’re fully insured. On top of that, we’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we have been trading since 2009.

Any of them serving cooked food has an extract to keep clean, from canopy to discharge. Night work suits London kitchens, and roads and loading bays tend to be quieter too. Environmental health officers from Harrow council inspect food businesses in Harrow Weald. A greasy canopy or dripping filters are the sort of thing an inspection can pick up. Before-and-after photos from each clean are a simple way to show the extract is in hand.
School kitchens, at schools like Salvatorian Roman Catholic College for example, are normally cleaned in the holidays so no lunches are lost. A hospital like Northwick Park Hospital, about 2.1 miles south, is the kind of site where a kitchen may cook for patients, staff and visitors all day.

How the job changes from site to site
Horizontal duct runs
Flat duct runs collect grease along their base. Readings are taken along each run through its access panels.
Vertical risers
In buildings with several floors, the riser may pass through other tenants’ space, so we arrange access ahead of time.
Leave it or put it right?
If there’s a fire or a claim, your insurer may ask for TR19 records. Without them, a claim can be reduced or refused. Getting an inspection done now starts that paper trail. London sites work long hours, and the longer a job is left, the bigger it gets.
Every site is different, so we price each one individually. Size, access, the condition of the system and when we can work all play a part.

How it works
Before we leave, we walk the area with whoever is on site. Anything we couldn’t reach or that needs attention is pointed out there and then, and the same goes into the written report. All told, the work takes a couple of hours for a typical kitchen extract system. Before any visit in Harrow Weald, we agree where the van can stop and how equipment reaches the system.
- First we book a time that won’t disrupt cooking.
- We look over the canopy, plenum, ducts, fan and discharge.
- Grease readings are taken at set points using WFTT or DTT.
- We photograph the test points and record any sections we cannot reach.
- We send a report setting out the readings, photos and next steps.
Preparing for the visit
- Arrange a key holder or contact on site
- Let us know when the site is closed or quiet
- Plan for cooking equipment or plant to be off before we arrive
Ask for a quote
Here’s what helps us quote: the address, the type of site and when it’s open, pictures of the system and any previous report or certificate. Once you have those, phone us on 0345 646 2711, or email photos.
Advice
Between visits
Here’s the after-treatment advice, short and simple:
- Keep TR19 certificates, readings and reports together
- Report grease dripping from the canopy
- Keep access panels clear and unpainted
- Never cook with filters missing
Each report suggests the next clean and the next test, based on the readings and how the kitchen is used.
Fit access panels where the survey finds sections cannot be reached, so every part of the duct can be cleaned.
What affects the quote in Harrow Weald
You’ll get a fixed price before work begins. It takes into account:
- The times the site is available
- The size of the system
- Where the site is and how we reach it
- How easy every part is to reach
What you pay reflects the actual work. That’s why we survey first, from photos or on site, and why the quote is fixed before any work starts.
Helping us quote
To help us quote quickly, send us:
- Where the site is and what kind of site it is
- Your opening hours and when the area is out of use
- A few general shots of the system
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
Some systems can be priced from photos; others need a survey. Larger sites, and anything hidden behind walls, ceilings or floors, are normally surveyed first. Either way, the quote is fixed before any work is booked.
Harrow Weald questions
Do you work overnight in Harrow Weald?
Yes. We work evenings, overnight and at weekends. It means the site in Harrow Weald keeps running as normal. Your opening times are the first thing we ask for.
Do you clean school canteen extracts around Harrow Weald out of term?
Yes. The holidays are the usual time for school work. The FSA’s register shows about 8 schools and colleges with food registrations within roughly a mile and a half of Harrow Weald. Send us your term dates when you call us on 0345 646 2711, or email photos, and we’ll fit the work in.
What about areas you cannot 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.
Do we have to follow TR19 by law?
No, not in itself. The Fire Safety Order 2005 still requires the responsible person to manage fire risk, which in a kitchen includes grease in the extract. Many insurance policies also require TR19 adherence.
Do you carry out TR19 audits for insurers?
Yes. Our TR19 audits cover readings, pictures, access and a recommended cleaning interval. It’s set out for your insurer or broker.

Duct Doctor is a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we carry full insurance.
What does TR19 inspection cost?
Size, condition, access and working hours all affect the cost. Call for a fixed quote and we will normally reply within one working day.
When should we have our next grease test?
Enough to be sure grease stays within the TR19® Grease figures between cleans. The readings themselves tell you if the interval needs to change.
