How we handle TR19 inspection in Brockley Hill
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 quote and the clean fit the real system. We are often asked to deal with an insurer’s request for a TR19 audit and sites with gaps in their extract records, on wet film thickness tests, deposit thickness tests and insurer audits.
London kitchens are often tucked into basements or the back of a building, with extract ducts that can climb several floors to discharge at roof level. In Brockley Hill, as elsewhere in the capital, a long duct run means more access points to open and more grease to remove.
For insurers and inspectors, the record counts. So every job comes with a written report and photos, and grease extract cleans come with a TR19® certificate issued through the BESCA Vent Hygiene Elite portal.

Leave it or put it right?
If a kitchen in Brockley Hill has been cleaned on the same calendar for years, there’s no way to know if that interval is right without measuring. Measured readings let a competent person set the interval. A booked night’s work in Brockley Hill costs you no trading time; an unplanned closure does.
Putting the work off seldom saves money. Build-up, wear and faults tend to get worse, not better, which can make the next visit longer. If you are not sure what’s needed, ring 0345 646 2711 or send us an email and we will give you an honest view and a fixed quote.

How it works
A visit follows the same order every time: sheeting and protection first, isolate whatever needs isolating, do the work, 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. A name and number for whoever controls access to the building in Brockley Hill saves time on the night.
- First we look at the system’s cleaning history, if there is one.
- The layout is traced from the canopy to the discharge.
- Access panels are located and any missing ones noted.
- Grease readings are taken and pictures recorded.
- You get a report and a fixed quote for the clean.
Preparing for the visit
- Allow time for equipment near the work to be turned off and cool down
- Mention any locked doors, roof access or ceiling voids
- Have your last certificate or report to hand

Brockley Hill kitchens: local notes
According to Food Standards Agency records, there are about 5 pubs, bars and clubs in Brockley Hill and the streets around it, up to about 1.5 miles out. Wherever they cook, the canopy, duct and fan collect grease just as a restaurant’s do. Kitchens in Brockley Hill get their food hygiene inspections from Harrow council. The cleanliness of the kitchen and its equipment, extraction included, is part of what they check. Our report lists what was cleaned and when, which is useful to have ready. Night work suits London kitchens, and roads and loading bays tend to be quieter too.
Kitchens that cook twelve hours or more a day, as some healthcare kitchens do, fall into BESA’s three-monthly minimum; Royal National Orthopaedic Hospital is the nearest hospital to Brockley Hill, about within half a mile north-west. Church and community hall kitchens, near St Peter or anywhere around Brockley Hill, are easy to forget, but their extracts collect grease like any other.

Part by part
Restaurants, pubs and hotels
Heavy use under BESA guidance, 12 to 16 hours a day, means a clean at least every 3 months, with testing showing whether more is needed.
Canopy and plenum
Behind the filters, the plenum catches plenty of grease. Readings and pictures are taken in the plenum as part of every survey.
Multi-site and managed buildings
The Fire Safety Order 2005 puts the duty to manage fire risk on the responsible person, and that can be the employer, the owner, a landlord, a facilities manager or a managing agent. Where responsibility is shared, records matter even more.
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.
Between visits
Simple habits between visits make a real difference. Our advice:
- Tell us if menus or opening hours change
- Diary the next grease test and clean
- Keep the route to access panels clear
- Flag oily drips near the extract
Readings of 500 microns or more are highlighted as needing immediate spot cleaning, and we can arrange it.
Keep filters clean and in place. Missing or damaged filters let grease straight into the plenum.
Questions from Brockley Hill
Can a school canteen extract in Brockley Hill be done out of term time?
Yes, holiday work suits schools best. The FSA’s register shows about 13 schools and colleges with food registrations within roughly a mile and a half of Brockley Hill. Just give us a ring on 0345 646 2711 or use the quote form with your term dates and we’ll plan around them.
Who carries out food hygiene inspections in Brockley Hill?
That’s Harrow council, whose environmental health officers carry out food hygiene inspections in Brockley Hill. Ratings are published by the Food Standards Agency, so a clean extract and good records are worth keeping up.
Why survey before a clean?
A survey finds out how the system is laid out, how dirty it is and what can be reached, so the clean goes to plan. Any access problems are flagged ahead of the clean.
Is TR19 a legal requirement?
No, not in itself. The Fire Safety Order 2005 still requires the responsible person to manage fire risk, and grease in the extract is part of that. Many insurers also expect TR19 cleaning.
What do you do with what you remove?
We contain it and take it with us. Grease, debris and waste water are collected as the work goes on rather than letting it spread.
What is a WFTT or DTT grease test?
Readings are taken using the Wet Film Thickness Test or the Deposit Thickness Test, then compare them with the TR19® Grease figures.
What does TR19 inspection cost?
We don’t publish prices, because the cost depends on the job: the size of the system, its condition, access and when we can work. You get a fixed price before we start.
How long does grease testing take?
Expect it to take a couple of hours for a typical kitchen extract system. We fit it around when the kitchen is closed or quiet.
Signs you need TR19 inspection in Brockley Hill
Not every section of a kitchen extract is easy to get to, and grease can be missed there clean after clean. An inspection of a system in Brockley Hill shows where access panels are missing, so the gaps can be closed.
Most sites get in touch after spotting something like this:
- Checking the result of a recent clean
- Kitchens taken over with no cleaning records
- Heavy grease suspected in the plenum or ducts
- Extracts that have never been grease tested
Older buildings often hide long, awkward duct runs, and if you run a kitchen at a historic venue in the area (Headstone Manor is about 3.4 miles south-west), access may need planning.
Before you book anyone
- What hours they’ll be on site
- Whether the whole system is included, or only the parts that are easy to reach
- Whether they recommend a next date
- Proof of insurance
What TR19 inspection can’t fix
To be straight with you, there are a few things this work won’t fix:
- Removing the grease, which is a separate clean
- A faulty or failing extract fan
- The responsible person’s own fire risk assessment
If you’re not sure, just ring 0345 646 2711 or drop us a line and we will give you a straight answer.
