About our TR19 inspection in Pratt's Bottom
Think of a TR19 inspection as the diagnosis before the treatment. We look at the system, take grease readings and photograph what we find, so the clean can be planned properly. If you have post-clean verification after another contractor’s clean and uncertainty over how often to clean, we can help, from pre-clean surveys, wet film thickness tests and insurer audits onwards.
In a London area like Pratt's Bottom, a kitchen extract often passes through shared space on its way out: a riser, a service void, the floors above. Grease in a duct like that is a fire risk to the whole building, not just the kitchen, which is why keeping it clean to TR19® matters.
Duct Doctor has been trading since 2009, and we are 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.

Part by part
Canopy and plenum
Behind the filters, the plenum catches plenty of grease. We take readings there and photograph it as part of every survey.
Extract fan and discharge
The extract fan and its housing collect grease too. We check and test them as part of the inspection.
In-house cleaning or a specialist?
Some jobs should never be done in-house: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease call for the right kit, training and safe access. Leave those to us.
Away from the kitchen, the in-house job is mainly checking: clear grilles, a log of filter changes and reporting anything odd. Cleaning inside ducts and units is specialist work.
Leave it or put it right?
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. In a London building, a problem in a duct, damper or fan rarely stays in one unit.
Kitchens, offices, schools and hospitals are all priced the same way: the size of the job, access, condition and working hours. Ask for a fixed quote and we’ll explain each part.

For landlords and multi-site operators
For anyone managing more than one site, we can plan visits across the whole estate and price them together. Every building has its own written report, so records stay tidy.
From a single site to a large estate, the standard is the same: a survey first, a fixed quote, the work timed around the site and a report with photos.
How the visit works
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. Getting kit into a London building takes planning, so let us know where we can load and park in Pratt's Bottom.
- After the clean, we arrange a time to check the system.
- We open the access points used on the clean.
- Grease readings are taken again at set points.
- Photos are taken to show the condition after the clean.
- The results are reported, with anything missed flagged.
Preparing for the visit
- Clear the space around the work
- Plan for cooking equipment or plant to be off before we arrive
- Let us know when the site is closed or quiet

Between visits
Looking after the system between visits is straightforward, and it makes the next visit easier:
- File every inspection report with your certificates
- Book the next test on the date in the report
- Share inspection reports with your insurer or broker when asked
- Report grease dripping from the canopy
The audit report is set out to pass straight to your insurer or broker, with readings, photos and any areas not accessible.
Regular grease readings keep the cleaning interval honest. It shows if build-up is speeding up.

TR19 inspection in Pratt's Bottom: the local picture
The Food Standards Agency lists about 3 pubs, bars and clubs as registered food businesses within about 1.5 miles of central Pratt's Bottom. Wherever they cook, the canopy, duct and fan collect grease just as a restaurant’s do. The fire and rescue service for Pratt's Bottom is London Fire Brigade. Fire and rescue authorities enforce the Fire Safety Order in most non-domestic premises, and in a kitchen that fire risk includes the grease in the extract. Kitchens in Pratt's Bottom get their food hygiene inspections from Bromley council. 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.
Commuter trade near Knockholt station can mean long cooking hours, and long hours put a kitchen into BESA’s more frequent cleaning bands. Healthcare kitchens, like those at hospitals such as Orpington Hospital (about 1.6 miles north-west), often cook for long hours, which puts them in BESA’s heavier-use bands. Term dates shape school work: for a school like Pratts Bottom Primary School, an extract clean fits neatly into a half-term or summer break.
