About our TR19 inspection in Donnybrook Quarter
Under TR19® Grease, the mean grease thickness should stay at or below 200 microns between cleans, and 500 microns or more at any point needs immediate spot cleaning. Grease testing shows which side of those lines you’re on. If you have insurers asking for TR19 evidence and systems that need surveying before cleaning, we can help, from post-clean checks, wet film thickness tests and access surveys onwards.
London kitchens tend to trade late and open early, so work in Donnybrook Quarter is normally booked for the night or the early hours. Parking, loading and access to the roof are agreed with the building before the night of the clean.
Duct Doctor has been trading since 2009, as a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we carry full insurance.

TR19 inspection around Donnybrook Quarter
There are about 615 restaurants, cafés and works canteens and about 197 takeaways and sandwich shops across Donnybrook Quarter and its immediate surroundings (about a mile and a half), according to the Food Standards Agency’s register. Kitchens like these cook for very different hours, and grease testing shows which extracts need cleaning soonest. In London, kitchens are typically cleaned overnight, when the kitchen is closed and loading is easier. Food hygiene inspections in Donnybrook Quarter are the job of Tower Hamlets council’s environmental health team. A greasy canopy or dripping filters are the sort of thing an inspection can pick up. A dated certificate in the maintenance file answers the question before it’s asked.
Kitchens that cook twelve hours or more a day, as some healthcare kitchens do, fall into BESA’s three-monthly minimum; St Clement's Hospital is the nearest hospital to Donnybrook Quarter, about 0.7 miles south. For kitchens close to Hackney Wick station, where the day often starts early and ends late, the extract can be cleaned overnight.

Staff cleaning versus specialist work
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’s our job.
Your own staff can handle the daily basics: wiping canopies, washing grease filters and recording it in a log. What they cannot safely do is clean inside the ductwork, the fan or the risers, which is where we come in.
For landlords and multi-site operators
Running several sites is easier with one contractor. We work across London and the South East, so a run of sites can go into one programme and kept on a regular cycle.
Whether it’s one building or many, the standard is the same: a survey first, a fixed quote, the work timed around the site and a report with pictures.
What the work involves, part by part
Canopy and plenum
Clean-looking filters don’t mean a clean plenum. That’s why we test behind them.
Extract fan and discharge
Grease builds up on the fan blades and inside the housing. We check and test them as part of the inspection.
What we do, step by step
On the day, we arrive at the time agreed with you, which is often after service, overnight or at a weekend. Equipment that has to be off is switched off and allowed to cool first, and the area around the work is covered and protected. On site, it takes a morning or less for one kitchen, more where there are several systems. Security desks and permits-to-work are routine in London, so let us know what your building in Donnybrook Quarter needs from us.
- After the clean, we arrange a time to check the system.
- The same access points are opened up.
- We repeat the WFTT or DTT readings.
- Photos are taken to show the condition after the clean.
- We report the findings and flag any areas that need more work.
Preparing for the visit
- Plan for cooking equipment or plant to be off before we arrive
- Clear the space around the work
- Let us know about permits to work or site inductions
Getting a quote
Here’s what helps us quote: where the site is, what it is and its opening hours, a few photos and the last certificate or report, if there is one. Then call 0345 646 2711 or send us an email.
Advice
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. Shared walls, risers and roofs mean a problem at one London site seldom stays put.
Leaving it longer rarely makes the work cheaper. Problems in a system tend to grow, and a neglected system can mean more work. If you’re not sure what’s needed, call us on 0345 646 2711, or send details by email and we’ll give you an honest view and a fixed quote.

More services for Donnybrook Quarter
Donnybrook Quarter: your questions answered
Who is the fire and rescue service for Donnybrook Quarter?
London Fire Brigade is the fire and rescue service for Donnybrook Quarter. A recent cleaning certificate and a note of the next clean date show that grease in the extract is being managed.
Who inspects food businesses in Donnybrook Quarter?
Kitchens in Donnybrook Quarter are inspected by Tower Hamlets council’s environmental health officers. How often a business is inspected depends on the risk rating the council gives it, so it’s worth staying ready all year.
Can you price the work without visiting?
Yes, if we can see what we need. Otherwise, we book a survey at a time that suits the site, then a fixed quote.
Do you look at the system first?
Yes, every time. Diagnosis comes before treatment: the survey tells us what the system needs and how to reach it, and the quote is based on that.
Can you work evenings and weekends?
Yes. Give us your opening hours with your enquiry and we’ll book around them.
Do we have to follow TR19 by law?
No. TR19® is a specification, not a statute. Without TR19 records, an insurance claim can be reduced or refused, so it matters in practice.
Which sectors do you work in?
We work for restaurants, pubs, hotels, schools, colleges, hospitals, care homes, offices and shops, plus food production and leisure sites.
How do you measure grease in a kitchen extract?
Readings are taken using the Wet Film Thickness Test or the Deposit Thickness Test, and set against the TR19® Grease figures.
Common problems we fix in Donnybrook Quarter
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.
The symptoms we are asked about most include:
- Cleaning intervals that may not suit the kitchen
- Missing TR19 certificates or history
- Systems that need surveying before cleaning
- Confirming a clean reached the whole system
If you run a church or community hall kitchen, near St Paul Old Ford or elsewhere in Donnybrook Quarter, its extract still collects grease from every lunch and event.
Before booking anyone
- Proof of insurance
- Proof of accreditation you can verify
- Whether the work can be done while the site is closed
- What’s included in the scope, part by part
When it’s something else
Before booking, it helps to know what’s not included:
- Installation problems, which fall under design guidance such as DW172
- Removing the grease, which is a separate clean
- Hidden runs that need access panels first
