TR19 inspection in Bow
If you’ve taken over a kitchen in Bow and do not know when the extract was last cleaned, an inspection is the place to start. We survey the system, measure the grease and tell you what needs doing, before any cleaning is booked. Common call-outs are for confirming a clean reached the whole system and uncertainty over how often to clean, on access surveys, deposit thickness tests and pre-clean surveys.
In a London area like Bow, a kitchen extract often passes through shared space on its way out: a riser, a service void, the floors above. A duct fire there can reach parts of the building far from the range, so a regular TR19® clean protects everyone in it.
We are CHAS and SafeContractor accredited, we hold 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.

What a clean will not put right
We won’t sell you work that does not address the problem, so these are the things it won’t cover:
- Installation problems, which fall under design guidance such as DW172
- Sections with no access, until panels are fitted
- Fan breakdowns, which need a repair visit
If you are not sure, just phone us on 0345 646 2711 or drop us a line and we’ll give you a straight answer.

In-house cleaning or a specialist?
Logging matters as much as cleaning. A simple log of filter washes, wipe-downs and checks helps show that the system is managed between specialist visits, next to our reports.
Good housekeeping makes our visits easier, not unnecessary. Clean filters and tidy surfaces slow the build-up, but the parts you can’t see still need a specialist at the right interval.
Bow questions
What do you need to know about parking in Bow?
We plan it in advance, so let us know about loading bays, permits and access rules at the building. Where restrictions apply in the day, an evening or overnight visit usually gets round them.
Do you clean school canteen extracts around Bow out of term?
Yes. The holidays are the usual time for school work. Food Standards Agency records list about 65 schools, colleges and universities with registered kitchens within about a mile and a half of Bow. Booking early in the term gives the best choice of holiday dates.
Will you produce a report for our insurer?
Yes. We inspect the system and produce a report with grease readings, pictures and any inaccessible areas. It’s set out for your insurer or broker.
What’s TR19?
TR19® is BESA’s specification for ventilation hygiene. TR19® Grease, a standalone specification since 2019, covers grease in kitchen extract systems, while TR19® Air covers other supply and extract ductwork.
Do you survey before quoting?
Yes, always. We diagnose before we treat: the survey tells us what the system needs and how to reach it, and the quote is based on that.
What happens on a pre-clean survey?
We survey, measure and photograph the system first. We can work from photos and details, or visit, as suits the job.
What about areas you can’t get to?
They’re marked on the report. In ductwork, new access panels are often the answer, which we can install.
Is a quote from photos possible?
Yes, where the pictures show enough. If not, a site survey comes first, then a fixed quote.
Keeping the system healthy
Aftercare is simple, and it makes the next visit easier:
- Tell us if menus or opening hours change
- Look out for grease drips round the canopy edge
- Wipe the canopy surfaces regularly
- Keep the route to access panels clear
After post-clean verification, file the results with the cleaning certificate. The pair gives a clear record of the clean and the check.
Clean, correctly fitted filters stop more grease reaching the duct. Missing or damaged filters let grease straight into the plenum.
Why it’s worth doing now in Bow
Sites in Bow that have never measured grease can’t tell whether their cleaning interval suits the kitchen. Testing gives you the evidence to set it properly. A building in Bow may have flats or offices above and alongside, and a fault in the system can affect them too.
No two sites are the same, so we price each one individually. The size of the job, how we reach it, its condition and the working hours all play a part.

What happens on the day
Every visit runs to the same pattern: protect the area, isolate whatever needs isolating, do the work, clear away and leave you the report. On site, the work takes an hour or two for a single kitchen, longer for a large or complex system. Night and weekend working is normal for us in London, and a site in Bow is no exception.
- Post-clean verification is booked once the clean is done.
- We open the access points used on the clean.
- Grease readings are taken again at set points.
- We photograph each area to record how it was left.
- The results are reported, with anything missed flagged.
How to prepare
- Clear the space around the work
- Agree a time when the area can be out of use
- Make sure equipment near the work can be switched off and left to cool
How to get a quote
Every quote begins with a look at the system, either from pictures and details you send or from a site visit. Then we send a fixed price, before we start.

Bow kitchens: local notes
The Food Standards Agency lists about 84 pubs, bars and clubs and about 17 hotels and guest houses as registered food businesses in Bow and the streets around it, up to about 1.5 miles out. A pub or hotel kitchen that cooks every day builds up grease in its extract like any other. Bow is covered by London Fire Brigade. The Fire Safety Order puts the duty on whoever runs a kitchen to control its fire risk, and a greasy duct is fuel. London jobs typically start after the last service, with loading and roof access agreed with the building first.
If you run a café or takeaway near Hackney Wick station, early starts and late finishes leave little time to clean, so overnight extract cleaning suits. Healthcare kitchens cannot easily close, so their extracts are cleaned overnight or between meal services; the nearest hospital to Bow is St Clement's Hospital, about within half a mile south. Where a hall near St Paul Old Ford, or anywhere in Bow, hosts lunch clubs or events, its extract gathers grease just as a café’s does.

Landlords, agents and facilities managers
When the building owner and the occupier are different, the lease normally sets out who maintains what. We can quote either party and send the paperwork to whoever needs it.
For anyone managing more than one site, we can plan visits across the whole estate and price them together. Each site gets its own report and photos, so records stay tidy.
