How we handle TR19 inspection in Holloway Down
Taking on a kitchen in Holloway Down with no cleaning records? Start with an inspection. You get readings, pictures and a clear view of what’s needed, before any cleaning is booked. The work covers deposit thickness tests, insurer audits and pre-clean surveys, and common reasons people get in touch are surveys needed before quoting a full clean and sites with gaps in their extract records.
London kitchens tend to trade late and open early, so work in Holloway Down 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.
We have 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’re fully insured.

What happens on the day
We start by comparing what we find with the survey or your photos. Anything unexpected is raised with you before we go further. From there, it takes around an hour or two per canopy and duct system. Loading bays, visitor permits and roof access are the first things we ask about for a site in Holloway Down.
- We agree a time when the kitchen is closed or quiet.
- We look over the canopy, plenum, ducts, fan and discharge.
- We take WFTT or DTT readings at set points along the system.
- Photos are taken at each point, and access gaps noted.
- You get a report with readings, photos and recommendations.
Preparing for the visit
- Let us know how we reach the system, including roofs, risers and plant rooms
- Tell us where we can park and unload
- Agree a time when the area can be out of use

There’s no standard price list, because every site is different. We look at your system first, from photos or on a visit, and then give you a fixed quote. To get going, give us a ring on 0345 646 2711 or email us.
Advice
Questions from Holloway Down
Which council inspects kitchens in Holloway Down?
That is Newham council, whose environmental health officers carry out food hygiene inspections in Holloway Down. Ratings are published by the Food Standards Agency, so a clean extract and good records are worth keeping up.
Who enforces fire safety at workplaces in Holloway Down?
Holloway Down is in the area of London Fire Brigade. Records of extract cleaning are a sensible thing to have ready if a fire safety officer carries out an audit.
How do you measure grease in a kitchen extract?
Grease thickness testing measures the layer of grease on the duct surfaces, using the Wet Film Thickness Test (WFTT) or Deposit Thickness Test (DTT). The results are given in microns.
How much time does an inspection need?
An inspection takes a morning or less for one kitchen, more where there are several systems. Large or multiple systems take longer, so call us on 0345 646 2711 or email us and we’ll plan it.
Which accreditations do you hold?
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.
Can you look after several sites?
Yes. Our area covers London and the South East, so we can schedule a run of sites on one programme. Every site has its own report.
Do you work out of hours?
Yes. Evenings, nights and weekends are normal working hours for us, so the site doesn’t lose a service.
How do you keep the site clean during the work?
We cover floors and nearby surfaces with sheeting before any work starts, and anything we remove is contained. Before we leave, we tidy up and clean down.
Multi-site and managed buildings
We also work for facilities teams across offices, schools and healthcare in Holloway Down and across Greater London. Larger estates can be phased building by building to keep disruption down.
Running several sites is easier with one contractor. We cover South East England and London, so a run of sites can go into one programme and kept to a regular schedule.
Grease, kitchens and Holloway Down
Food Standards Agency data counts about 469 restaurants, cafés and canteens and about 246 takeaways and sandwich shops across Holloway Down and its immediate surroundings (about a mile and a half). Kitchens like these cook for very different hours, and grease testing shows which extracts need cleaning soonest. Fire safety in Holloway Down falls to London Fire Brigade. In most workplaces, including commercial kitchens, it’s the fire and rescue authority that enforces the Fire Safety Order. Most London extract cleaning happens at night, after the last service.
Healthcare kitchens, like those at hospitals such as Queen Mary's Hospital for the East End (about 0.9 miles south), often cook for long hours, which puts them in BESA’s heavier-use bands. Where a hall near Holy Trinity & St Augustine of Hippo, or anywhere in Holloway Down, hosts lunch clubs or events, its extract gathers grease just as a café’s does.
Holloway Down is about 1 mile north of Stratford, in Greater London. Across the E11 area, we cover TR19 inspection for commercial sites. Holloway Down is one of 764 places in Greater London where we work for TR19 inspection. London is in our area too, around 6 miles away.

Staff cleaning versus specialist work
For ventilation and air handling systems, in-house care is mostly about checks: keeping grilles clear, noting unusual noise or smells and logging filter changes. The inside of ducts and units needs a specialist.
Staff cleaning and specialist work are not the same thing. Wiping filters daily and washing them weekly keeps the visible parts in order, but grease that has passed the filters is out of reach. Reaching it takes a specialist with the right equipment.
Looking after it afterwards
Good habits slow the build-up between visits. A few tips:
- Mention new equipment or longer hours at the next test
- Diary the next grease test and clean
- Report grease dripping from the canopy
- Keep the route to access panels clear
Each report suggests the next clean and the next test, from the measured grease and the kitchen’s hours.
Keep all TR19 records together so the history is easy to show.
What the work involves, part by part
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.
Horizontal duct runs
Sections without access are recorded so panels can be added.
Do you need TR19 inspection in Holloway Down?
Some parts of a system are hard to reach, and grease can be missed there clean after clean. An inspection of a system in Holloway Down shows where access panels are missing, so panels can be fitted.
What we are most often called out for:
- Ductwork where grease may be over the TR19 limits
- Uncertainty over how often to clean
- Surveys needed before quoting a full clean
- Systems cleaned on a calendar with no measurements
Term dates shape school work: for a school like The Jenny Hammond Primary School, an extract clean fits neatly into a half-term or summer break.
Questions to ask before you book
- If they look at the system before pricing
