TR19 Inspection in Vale of Health
Looking for TR19 inspection in Vale of Health? We survey first, send you a fixed quote and work around your opening hours, finishing with a written report and photos.

- Insurance renewals needing proof of TR19 cleaning

Common problems we fix in Vale of Health
Some parts of a system are hard to reach, and grease can be missed there clean after clean. A survey finds the sections that cannot be reached, so panels can be fitted.
Most sites get in touch after spotting one of these:
- Checking the result of a recent clean
- Extracts that may be over the 200 micron mean
- Insurance renewals needing proof of TR19 cleaning
- Extracts that have never been grease tested
A hall kitchen that only cooks for events, whether near Christ Church or elsewhere in Vale of Health, still needs its extract cleaned, just less often.
Questions to ask before you book
- What records you will receive afterwards
- Whether they’re fully insured
- Whether inaccessible sections are listed on the report
- What’s included in the scope, part by part
TR19 inspection for kitchens and businesses in Vale of Health
Insurance policies often require evidence of TR19® cleaning and inspection. Without it, a claim can be refused or reduced. A TR19 audit sets out the system’s condition, with readings and photos, for sites in Vale of Health and the rest of Greater London. If you have confirming a clean reached the whole system and systems that need surveying before cleaning, we can put it right, from post-clean checks, wet film thickness tests and pre-clean surveys onwards.
London kitchens are often tucked into basements or the back of a building, and the duct may run up through several floors before it discharges at the roof. For a kitchen in Vale of Health, that typically means a longer system to clean and more access panels to plan around.
Think of the report as the system’s health record: dated, with pictures, and showing what was done. For TR19® Grease cleans, the certificate comes through the BESCA Vent Hygiene Elite portal and sits alongside the report.

Vale of Health questions
Do you work overnight in Vale of Health?
Yes, nights and weekends are routine for us. The site is handed back ready to open. When you phone us on 0345 646 2711 or drop us a line, mention when the site is quiet.
Do you clean school canteen extracts around Vale of Health out of term?
Yes. Half-terms and the summer break are the natural time for school work. With about 62 schools and colleges on the FSA’s register within roughly a mile and a half of Vale of Health, it pays to plan holiday dates ahead. Booking early in the term gives the best choice of holiday dates.
Is a quote from photos possible?
Yes, where the pictures show enough. If not, a site survey comes first, then a fixed quote.
What is grease thickness testing?
It’s a measurement of how much grease is coating the inside of the extract, by WFTT or DTT. Each reading is recorded in microns.
How much notice do you need?
For planned work, earlier is better, especially if the next clean or test is due soon. Emergencies are different, because our line is open 24/7.
What do the grease readings need to be?
TR19® Grease says grease should not go over a mean of 200 microns between cleans. 500 microns or more at any point calls for immediate spot cleaning.
Why survey before a clean?
A survey finds out how the system is laid out, how dirty it is and what can be reached, before anyone starts cleaning. Any access problems are flagged ahead of the clean.
What do you do with what you remove?
Anything we remove is contained as we work and taken away with us, including grease, debris and dirty water. None of it is left on site.
What staff can safely do
Logging matters as much as cleaning. A dated log of in-house cleaning and checks shows an inspector that the system is looked after between visits, next to our reports.
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. Leave those to us.
What we do, step by step
Every visit runs to the same pattern: sheeting and protection first, isolate whatever needs isolating, carry out the TR19 inspection, clear away and hand over the paperwork. On site, the work takes an hour or two for a single kitchen, longer for a large or complex system. Security desks and permits-to-work are routine in London, so let us know what your building in Vale of Health needs from us.
- 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.
- We report the findings and flag any areas that need more work.
Before we arrive
- Mention any parking or loading restrictions
- Have your last certificate or report to hand
- 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, from your photos and details or, where that isn’t enough, a survey on site. Then we send a fixed price so you know the cost before we start.

Kitchen extracts in Vale of Health
The FSA’s food hygiene register shows about 372 cafés, restaurants and staff canteens and about 107 sandwich bars and takeaways across Vale of Health 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. Food hygiene inspections in Vale of Health are the job of Camden council’s environmental health team. A greasy canopy or dripping filters are the sort of thing an inspection can pick up. Keeping each certificate and photo report on file helps show the extract is looked after. The fire and rescue service for Vale of Health is 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.
For schools such as Christ Church Primary School, kitchen extract cleaning is typically booked for the holidays, when the canteen is closed. If you run a café or takeaway near Hampstead Heath station, early starts and late finishes leave little time to clean, so overnight extract cleaning suits.

What the work involves, part by part
Horizontal duct runs
Grease settles on the floor of horizontal ducts as the air cools. Readings are taken along each run through its access panels.
Canopy and plenum
The plenum behind the filters can carry a lot of grease. Readings and photos are taken in the plenum on every inspection.
What affects the cost of TR19 inspection
The survey tells us what the work involves. We look at:
- Whether it’s a one-off visit or part of a schedule
- When the work can happen, such as evenings, overnight or weekends
- Access, including roofs, risers and ceiling voids
- The condition we find in the survey
Several systems or sites on one quote can make for a more efficient booking. Tell us about everything you’d like looked at, and you will get one fixed quote.
Helping us quote
Before you ask for a quote, gather:
- Photos showing the whole system and its surroundings
- Your last certificate, test record or report
- Any symptoms, from odd noises to smells or leaks
- When the site is open and when it’s quiet
For TR19 inspection in Vale of Health, ring 0345 646 2711, or email photos. Tell us what kind of premises it is and when it’s open, and send pictures or your last report if you can. A fixed quote normally follows within one working day.
Between visits
Results last longer with the right care. We suggest:
- Clean grease off the canopy between professional cleans
- Share inspection reports with your insurer or broker when asked
- Keep the route to access panels clear
- Keep TR19 certificates, readings and reports together
If any reading is 500 microns or more, the report flags it for immediate spot cleaning, and we can quote to do it.
Close the access gaps found during inspection, so grease isn’t left building in hidden parts.
Why deal with it now?
Finding a hotspot early means a targeted spot clean rather than a bigger problem later. Left alone, grease keeps building between cleans. In Vale of Health, as across London, ductwork often passes through shared risers and other people’s space.
The cost depends on the size of the system, 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.
