TR19 inspection for kitchens and businesses in St John's Wood
Post-clean verification is a check carried out once the cleaning is done, with fresh grease readings, pictures and a look at the areas that were cleaned. It gives you evidence of how the system was actually left. If you have systems cleaned on a calendar with no measurements and extracts that may be over the 200 micron mean, we can put it right, from post-clean checks, pre-clean surveys and access surveys onwards.
London kitchens tend to trade late and open early, so work in St John's Wood 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.
Insurers, fire officers and environmental health officers all look at records. That’s why every job is written up in a report with pictures, plus a TR19® certificate through the BESCA VHE portal where the work is a TR19® Grease clean.

Questions from St John's Wood
Which fire authority looks after St John's Wood?
It’s London Fire Brigade, which covers St John's Wood. Records of extract cleaning are a sensible thing to have ready if a fire safety officer carries out an audit.
Which environmental health team covers St John's Wood?
The local authority for St John's Wood is Camden council, and its environmental health team does the inspecting. An officer may look up into the canopy, so clean filters on the day and a recent certificate on file both help.
Can you price the work without visiting?
Usually, yes. Send wide shots, close-ups of any access panels and anything that worries you, and we typically come back within one working day. If pictures are not enough, we’ll survey first.
Can you verify a clean after it’s been done?
It’s an inspection after cleaning, to show what state the system was left in, for our cleans and other firms’ alike.
How much notice should we give?
Earlier is better, particularly for night and weekend visits. Quotes usually come back within one working day, and emergencies are covered by our 24/7 line.
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 following it is the sensible course.
Can you look after several sites?
Yes. Our area covers London and the South East, so we can schedule a run of sites as one programme. Every site has its own report.
Do you look at the system first?
Yes. Every job is surveyed first, from your photos and details, or with a visit where needed. Then you get a fixed quote.
Why it’s worth doing now in St John's Wood
If there’s a fire or a claim, your insurer may ask for TR19 records. Missing records can put a claim at risk. An up-to-date inspection report is a good place to start. Leaving it on a busy London site only adds to the work.

Fixed quotes for TR19 inspection in St John's Wood
The survey tells us what the work involves. We look at:
- Where the site is and how we reach it
- The number of sites or systems
- Site requirements such as sign-in and permits
- When the work can happen, such as evenings, overnight or weekends
The price reflects the work, not guesswork. That is why every job is surveyed first, and why the quote is fixed before we start.
What to send for a quote
Photos let us diagnose from a distance. The most useful are:
- The roof, plant room or outside wall the system runs to
- Any access panels or hatches you can see
- The paperwork from the last visit, if you have it
- Where the site is and what kind of site it is

What your team can do, and what needs us
Logging matters as much as cleaning. A simple log of filter washes, wipe-downs and checks shows an inspector that the system is looked after between visits, next to our reports.
Day-to-day cleaning is something your team can do: wiping down canopy surfaces, cleaning filters and keeping a simple log. What they cannot safely do is clean inside the ductwork, the fan or the risers, which is where we come in.

St John's Wood kitchens: local notes
Food Standards Agency records include about 81 pubs and bars and about 80 hotels and guest houses within about 1.5 miles of central St John's Wood. Wherever they cook, the canopy, duct and fan collect grease just as a restaurant’s do. It’s Camden council that sends environmental health officers to food businesses in St John's Wood. They look at how clean the premises and equipment are, and the kitchen extract is part of that. Keeping each certificate and photo report on file helps show the extract is looked after. St John's Wood 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.
Where a hall near Church of All Souls, or anywhere in St John's Wood, hosts lunch clubs or events, its extract gathers grease just as a café’s does. For kitchens close to South Hampstead station, where the day often starts early and ends late, the extract can be cleaned overnight.

Keeping the system healthy
Simple habits between visits make a real difference. We recommend:
- Keep TR19 certificates, readings and reports together
- Keep grease filters clean and fitted properly
- Report grease dripping from the canopy
- Keep to the recommended interval
The report recommends when the system should next be cleaned and tested, from the measured grease and the kitchen’s hours.
Keep filters clean and in place. Gaps around filters let grease get past them.
Signs you need TR19 inspection in St John's Wood
Grease in a duct is flammable fuel. Flames from the range can be pulled into the canopy and travel through the ducts to other parts of the building. Knowing how much there is lets you act before it becomes a hazard.
Look out for any of the following:
- Systems cleaned on a calendar with no measurements
- Checking the result of a recent clean
- An insurer’s request for a TR19 audit
- Pre-clean surveys before a first TR19 clean
If you look after a school kitchen, at a school such as George Eliot Primary School or anywhere near St John's Wood, the holidays are the usual time for a TR19® clean.

The process
Night work is normal for us. A lot of visits happen overnight or at weekends, so the site can open as normal afterwards. The visit itself takes anything from an hour for a small canopy and short duct to a good part of a day for a large site. Most London sites cannot stop for the day, so work in St John's Wood is typically done overnight, early in the morning or at weekends.
- First we look at the system’s cleaning history, if there is one.
- We follow the extract from canopy to discharge.
- We note where access panels are and where more are needed.
- We measure the grease and photograph each point.
- You get a report and a fixed quote for the clean.
Getting ready for the visit
- Tell us where we can park and unload
- Make sure equipment near the work can be switched off and left to cool
- Find the previous report, if there is one
