TR19 inspection for kitchens and businesses in Sudbury Hill
Insurance policies often require evidence of TR19® cleaning and inspection. 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 Sudbury Hill and the rest of Greater London. The work covers wet film thickness tests, post-clean checks and deposit thickness tests, and the jobs we see most are checking the result of a recent clean and systems that need surveying before cleaning.
Kitchens in Sudbury 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, so a regular TR19® clean protects everyone in it.
Duct Doctor has been trading since 2009, and we’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we’re fully insured.

FAQs for Sudbury Hill
Can the work in Sudbury Hill be done at night or at weekends?
Yes, out-of-hours work is a big part of what we do. That way a site in Sudbury Hill doesn’t have to lose a day’s trading. Just ring 0345 646 2711, or email photos with your opening times and we’ll plan around them.
What do you need to know about parking in Sudbury Hill?
A loading bay, a visitor permit or off-street space near the site in Sudbury Hill makes the visit easier to plan. If the building has a loading slot system, we will book into it.
Are you accredited?
BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease, plus CHAS, SafeContractor and ISO 9001. We’re fully insured and have been trading since 2009.
Do you work in Sudbury Hill?
Yes. We work across Greater London, Surrey, Kent, Sussex, Hampshire, the Isle of Wight, Berkshire, Buckinghamshire, Oxfordshire, Hertfordshire and Essex, Sudbury Hill included.
When should we have our next grease test?
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.
Is TR19 a legal requirement?
No. TR19® is BESA’s specification and the industry benchmark, not legislation. The legal duty comes from the Regulatory Reform (Fire Safety) Order 2005, which requires the responsible person to reduce fire risk, and TR19® is what insurers and fire officers look to.
How far ahead should we book?
The more notice, the better, particularly for night and weekend visits. Quotes typically come back within one working day, and there’s a 24/7 line for emergencies.
What about areas you can’t get to?
We never leave them off the paperwork. You’ll know exactly which parts weren’t reached and why, and we can quote to improve the access.

Sudbury Hill kitchens: local notes
The FSA’s food hygiene register shows about 157 cafés, restaurants and staff canteens and about 130 sandwich bars and takeaways across Sudbury Hill and its immediate surroundings (about a mile and a half). Each kitchen extract among them can be measured for grease to set the right cleaning interval. Environmental health officers from Brent council inspect food businesses in Sudbury Hill. The cleanliness of the kitchen and its equipment, extraction included, is part of what they check. A TR19® certificate and photo report after each clean gives you a record to show an inspector. Sudbury Hill is covered by London Fire Brigade. Its fire safety officers can audit commercial kitchens, and grease in the extract is part of a kitchen’s fire risk.
Term dates shape school work: for a school like Sudbury Primary School, an extract clean fits neatly into a half-term or summer break. Church and community hall kitchens, near Church of St Andrew or anywhere around Sudbury Hill, are easy to forget, but their extracts collect grease like any other.

The process
There’s very little for your team to do on the day. A contact on site lets us in at the agreed time and points us to the system, and we take it from there. Afterwards, the area is left tidy and the written report follows. Before any visit in Sudbury Hill, we agree where the van can stop and how equipment reaches the system.
- We agree a time when the kitchen is closed or quiet.
- We look over the canopy, plenum, ducts, fan and discharge.
- Grease thickness is measured at set points by WFTT or DTT.
- We photograph the test points and record any sections we cannot reach.
- The findings go into a report with readings, pictures and a recommended next clean.
Before we arrive
- Clear the space around the work
- Tell us where we can park and unload
- Have your last certificate or report to hand
Getting 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 many jobs can be priced from that alone.
Advice
What affects the cost of TR19 inspection
We quote each job individually. This is what makes a difference:
- When the work can happen, such as evenings, overnight or weekends
- Site requirements such as sign-in and permits
- What state the system is in
- How easy every part is to reach
What you pay depends on how big the system is, what state it’s in and access to every part of it. You get a fixed price before we start, so you know where you stand.
What we need to know
The more you tell us, the more accurate the quote. When you get in touch, it helps to send:
- Where the site is and what kind of site it is
- A few general shots of the system
- Your opening hours and when the area is out of use
- How we’d reach plant on a roof or in a plant room
To get a fixed quote, call 0345 646 2711, or send details by email with the site type, your trading hours and a short description of the system. Photos and the last report, if you have one, make the quote quicker. You will typically have a quote within one working day.
What your team can do, and what needs us
When your team notices a problem between visits, like drips, unusual noise, smells or damaged filters, they should report it rather than try to fix it. We’ll take a look and give you a fixed quote.
Staff cleaning and specialist work aren’t the same thing. A daily filter wipe and a weekly filter wash keep grease down at the front of the system, but grease that has passed the filters is out of reach. Reaching it takes a specialist with the right equipment.
What TR19 inspection cannot fix
In fairness, there are a few things this work won’t fix:
- Sections with no access, until panels are fitted
- The legal duty, which stays with the responsible person
- Heavy deposits found on test, which still need cleaning
If you’re not sure, just call 0345 646 2711 or send us an email and we will give you a straight answer before booking.
What the work covers

Part by part
Schools, hospitals and care homes
Hospital and care home kitchens can cook all day, every day. Testing shows if the cleaning interval keeps pace.
Canopy and plenum
The plenum behind the filters can carry a lot of grease. We take readings there and photograph it as part of every survey.
Why act early in Sudbury Hill
Sites in Sudbury Hill that have never measured grease cannot tell whether their cleaning interval suits the kitchen. Testing gives you the evidence to set it properly. A busy site in Sudbury Hill builds up dirt and wear quickly, so putting it off makes the eventual job larger.
Putting the work off seldom saves money. Build-up, wear and faults tend to get worse, not better, which can make the next visit longer. If you are not sure what’s needed, give us a ring on 0345 646 2711 or send us an email and we’ll give you an honest view and a fixed quote.

When to call us in Sudbury Hill
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.
Most sites get in touch after spotting one of these:
- Heavy grease suspected in the plenum or ducts
- Kitchens whose menu or hours have changed
- Missing TR19 certificates or history
- Parts of the system left out of past cleans
For kitchens close to Sudbury & Harrow Road station, where the day often starts early and ends late, the extract can be cleaned overnight.
Questions to ask before booking
- How they set the interval to the next visit
- Whether the quote is based on a survey or pictures
- Whether they’re fully insured
- Whether a written report and photos are included
