TR19 inspection in Mapesbury
Many insurers ask for proof that kitchen extract systems are cleaned and inspected to TR19®. Missing records can lead to a claim being reduced or refused. A TR19 audit sets out the system’s condition, with readings and photos, for sites in Mapesbury and the rest of Greater London. The work covers deposit thickness tests, pre-clean surveys and insurer audits, and the jobs we see most are kitchens whose menu or hours have changed and insurance renewals needing proof of TR19 cleaning.
Across London, many commercial kitchens are squeezed into basements and narrow back-of-house spaces, and the duct may run up through several floors before it discharges at the roof. In Mapesbury, as elsewhere in the capital, a long duct run means more access points to open and more grease to remove.
The sign-off is always in writing: a written report, dated and illustrated with photos, plus a certificate through the BESCA Vent Hygiene Elite portal when the work is a TR19® Grease clean. It shows what was done and what, if anything, couldn’t be reached.

Keeping the system healthy
Here’s the after-treatment advice, short and simple:
- Do not box in or cover duct access panels
- Book the next test on the date in the report
- Keep grease filters clean and fitted properly
- Flag oily drips near the extract
You get a report with the grease readings, where they were taken and pictures of each point. File it alongside your TR19 certificates.
Fit access panels where the survey finds sections can’t be reached, so every part of the duct can be cleaned.
What TR19 inspection looks like in Mapesbury
The FSA’s food hygiene register shows about 204 restaurants, cafés and canteens and about 234 takeaways and sandwich shops in and around Mapesbury, up to about a mile and a half out. Kitchens like these cook for very different hours, and grease testing shows which extracts need cleaning soonest. Night work suits London kitchens, and roads and loading bays tend to be quieter too. Kitchens in Mapesbury get their food hygiene inspections from Brent council. 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.
Church and community hall kitchens, near St Michael the Archangel or anywhere around Mapesbury, are easy to forget, but their extracts collect grease like any other. Kitchens that cook twelve hours or more a day, as some healthcare kitchens do, fall into BESA’s three-monthly minimum; Neasden Hospital is the nearest hospital to Mapesbury, about 0.9 miles east. Term dates shape school work: for a school like St Joseph's RC Infant School, an extract clean fits neatly into a half-term or summer break.

What staff can safely do
For ventilation and air handling systems, in-house care is mostly about checks: clear grilles, a log of filter changes and reporting anything odd. The inside of ducts and units needs a specialist.
A few tasks are always specialist work: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease need training, the right equipment and safe access. That’s our job.
Mapesbury questions
Do you work at weekends in Mapesbury?
Yes, nights and weekends are routine for us. Your customers, staff or residents in Mapesbury needn’t be disturbed. Your opening times are the first thing we ask for.
How do you handle parking and loading in Mapesbury?
A loading bay, a visitor permit or off-street space near the site in Mapesbury makes the visit easier to plan. Working overnight, as we often do in London, normally makes it simpler.
How far ahead should we book?
It depends on the time you need and how big the job is. Tell us your preferred dates when you ask for a quote, and for anything urgent, ring our 24/7 emergency line.
What’s TR19?
TR19® is the BESA specification for keeping ventilation systems clean. TR19® Grease, a standalone specification since 2019, covers grease in kitchen extract systems, and TR19® Air covers general supply and extract systems.
How do you measure grease in a kitchen extract?
WFTT and DTT are the two methods for measuring grease thickness, in microns. We take readings at set points from canopy to fan.
Are you accredited?
We’re 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.
When should we have our next grease test?
Often enough to know the mean stays under 200 microns between cleans. If readings rise, the interval should shorten.
Can you verify a clean after it’s been done?
A post-clean check records grease readings and photos after the work, for our cleans and other firms’ alike.
Part by part
Horizontal duct runs
Flat duct runs collect grease along their base. Readings are taken along each run through its access panels.
Vertical risers
In buildings with several floors, the riser may pass through other tenants’ space, so access is planned in advance.
Why deal with it now?
A pre-clean survey avoids surprises on the night. Missing access panels, hidden duct runs and awkward fans are found before the cleaners arrive, and the quote reflects the real job. Leaving it on a busy London site only adds to the work.
When the work has to happen, how we reach it and how big the site is all affect the cost. We take each of them into account and give you a fixed price before any work starts.
