What TR19 inspection looks like in Harrow
The FSA’s data shows about 26 pubs and bars and about 3 hotels and guest houses registered in Harrow and the streets around it, up to about 1.5 miles out. Breakfasts, bar meals and functions all put grease into the extract wherever they’re cooked. London jobs normally start after the last service, with loading and roof access agreed with the building first. In Harrow, food businesses are inspected by environmental health officers from Harrow council. An officer looking round a kitchen will see the canopy, and grease there is hard to miss. Keeping each certificate and photo report on file helps show the extract is looked after.
Kitchens that cook twelve hours or more a day, as some healthcare kitchens do, fall into BESA’s three-monthly minimum; Clementine Churchill Hospital is the nearest hospital to Harrow, about 1 mile south-east. Church and community hall kitchens, near Church of St Peter or anywhere around Harrow, are easy to forget, but their extracts collect grease like any other.

TR19 inspection in Harrow
Insurance policies often require evidence of TR19® cleaning and inspection. Missing records can lead to a claim being reduced or refused. A TR19 audit sets out the system’s condition, with readings and pictures, for sites in Harrow and the rest of Greater London. Typical jobs include missing access panels found on survey and cleaning intervals that may not suit the kitchen, on insurer audits, access surveys and deposit thickness tests.
In a London area like Harrow, 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, which is why keeping it clean to TR19® matters.
Nothing is signed off by word of mouth: a dated report with photos of the work, and for TR19® Grease cleans, a certificate issued through the BESCA VHE portal. It shows what was done and what, if anything, couldn’t be reached.

Surveying first means the clean goes to plan. Access problems are spotted in advance rather than on the night, and the quote reflects the real job. In Harrow, a planned overnight visit is much easier than closing unexpectedly.
Whatever the type of site, the quote works the same way: the size of the job, access, condition and working hours. Call for a fixed quote and we will explain each part.

How the job changes from site to site
Canopy and plenum
The canopy itself is checked inside and out, with readings where grease collects.
Extract fan and discharge
A greasy fan works harder and wears faster. The inspection shows whether it needs cleaning now.
What we do, step by step
There are three stages on the day: getting the area ready, doing the work and signing it off. Getting ready means protecting surfaces and switching off what needs to be off, while signing off means the written report and photos. The middle part takes longest, and that takes anything from an hour for a small canopy and short duct to a good part of a day for a large site. Night and weekend working is normal for us in London, and a site in Harrow is no exception.
- First we look at the system’s cleaning history, if there is one.
- We follow the extract from canopy to discharge.
- Access panels are located and any missing ones noted.
- 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 about access, such as roof hatches, plant rooms, ceilings or locked areas
- Find the previous report, if there is one
- Plan for cooking equipment or plant to be off before we arrive

- The responsible person’s own fire risk assessment
- Ductwork that was designed or installed badly

In-house cleaning or a specialist?
Staff cleaning doesn’t replace a specialist visit; it supports it. Regular in-house cleaning slows the build-up, but hidden parts of the system still need specialist attention.
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, alongside our reports.
Common problems we fix in Harrow
As hot, greasy air travels up the duct, it cools and leaves a film behind. It often collects where nobody can see it: the plenum, bends and horizontal runs.
Signs it’s time to call us include:
- Checking the result of a recent clean
- Kitchen extract systems with no recent grease readings
- Kitchens taken over with no cleaning records
- Sections of duct that cannot be reached
Bursars and site managers at schools such as Whitmore High School tend to book extract cleaning for when the kitchen is empty.

FAQs for Harrow
Can you work in Harrow outside opening hours?
Yes. We work evenings, overnight and at weekends. It means the site in Harrow keeps running as normal. Let us know the hours you’re closed and we will book within them.
Which environmental health team covers Harrow?
In Harrow, it’s Harrow council that carries out food hygiene inspections. How often a business is inspected depends on the risk rating the council gives it, so it’s worth staying ready all year.
How much does TR19 inspection cost in Harrow?
The cost depends on the size of the system, its condition, access and timing. Ask us for a fixed quote and we’ll usually reply within one working day.
Is TR19 a legal requirement?
No, TR19® is not legislation. But the responsible person must assess and reduce fire risk under the Fire Safety Order 2005, and grease in the extract is part of that. Many insurers also expect TR19 cleaning.
Can you set up regular visits?
Yes, of course. Tell us what you have and how it’s used, and we’ll suggest a schedule and quote for it.
How much time does an inspection need?
Testing takes around an hour or two per canopy and duct system. Sites with several canopies take longer, and you can give us a ring on 0345 646 2711 or use the quote form to book it in.
What is grease thickness testing?
Grease thickness testing measures the layer of grease on the duct surfaces, using the Wet Film Thickness Test (WFTT) or Deposit Thickness Test (DTT). Each reading is recorded in microns.
At what point does grease need cleaning?
Two figures matter: a mean of no more than 200 microns between cleans, and 500 microns at any single point, which needs immediate spot cleaning. We show your readings against those figures.
