TR19 inspection for kitchens and businesses in Northolt
After a clean, post-clean verification checks the result, with fresh grease readings, pictures and a look at the areas that were cleaned. It shows whether the system was left in the condition the paperwork describes. If you have heavy grease suspected in the plenum or ducts and insurers asking for TR19 evidence, we can help, from insurer audits, wet film thickness tests and deposit thickness tests onwards.
London kitchens tend to trade late and open early, so work in Northolt is normally booked for the night or the early hours. Parking, loading and access to the roof are agreed with the building before the night of the clean.
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.

Your questions about TR19 inspection in Northolt
Can school kitchens in Northolt be cleaned in the holidays?
Yes. Half-terms and the summer break are the natural time for school work. There are about 40 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of Northolt. You can phone us on 0345 646 2711, or send details by email with the dates the site is empty.
Who enforces fire safety at workplaces in Northolt?
That’s London Fire Brigade. If a fire safety officer visits a commercial kitchen, they may ask about the fire risk assessment and how the extract is kept clean.
Do you carry out TR19 audits for insurers?
Yes. We inspect the system and produce a report with grease readings, photos and any inaccessible areas. It’s set out for your insurer or broker.
Is TR19 a legal requirement?
No. TR19® is BESA’s specification and the industry benchmark, not legislation. The law is the Fire Safety Order 2005, under which the responsible person must manage fire risk, and insurers, fire officers and EHOs look to TR19® as the benchmark.
Is Northolt in your area?
Yes. We work in Northolt and across Greater London, as part of our work across South East England and London. For a fixed quote, give us a ring on 0345 646 2711 or use the quote form.
What does TR19 inspection cost?
There’s no set price, as it depends on the job: how big it is, what state it’s in, how we reach it and the working hours. You get a fixed price before work begins.
Can you come out in an emergency?
Yes, 24/7. Office hours are Monday to Friday, 8am to 6pm, and the emergency line covers the rest.
What types of premises do you cover?
Any commercial site with kitchens or ventilation, from a single café to a large school. Hotels, schools, care homes, offices, shops and leisure sites are all part of our work.
Fixed quotes for TR19 inspection in Northolt
A fixed price needs a few facts first. We look at:
- Travel, parking and unloading
- Whether we need access equipment or extra panels
- What state the system is in
- The times the site is available
Putting the work off seldom saves money. Build-up, wear and faults tend to get worse, not better, and a neglected system can mean more work. If you’re unsure, call us on 0345 646 2711 or drop us a line for straight advice and a fixed quote.
What we need to know
What to send for a quote:
- Close-ups of filters, grilles, hatches or access panels
- Any symptoms, from odd noises to smells or leaks
- The site address and the type of premises
- Your last certificate, test record or report
Every quote begins with a look at the system, either from pictures and details you send or from a site visit. After that, you get a fixed price for the work, before we start.
Multi-site and managed buildings
From a single site to a large estate, you get the same standard: a survey first, a fixed quote, the work timed around the site and a report with pictures.
If you look after several sites, we can schedule visits across all of them on one quote. Each site gets its own report and photos, so records stay tidy.
What happens on the day
We work around your opening hours, not the other way round. We book the visit for a time the area is closed, whether that’s an evening, overnight or a weekend. Once we are in, the area is sheeted and anything that has to be off is turned off and cooled, and the work takes around an hour or two per canopy and duct system. Many London buildings have a managing agent, a security desk or a permit-to-work system, so tell us who to contact in Northolt.
- The visit is arranged for when the kitchen is not busy.
- The system is checked from canopy to discharge.
- Grease readings are taken at set points using WFTT or DTT.
- We photograph the test points and record any sections we cannot reach.
- The findings go into a report with readings, pictures and a recommended next clean.
Getting ready for the visit
- Mention any sign-in, permit or induction we need
- Make sure equipment near the work can be switched off and left to cool
- Arrange a key holder or contact on site

Advice
What happens if it’s left?
Sites in Northolt that have never measured grease can’t tell whether their cleaning interval suits the kitchen. Measured readings let a competent person set the interval. For a site in Northolt, fitting the work in overnight now is far easier than closing at short notice later.
The cost depends on how big the system is, what state it’s in and how easy it is to reach. You get a fixed price before work begins, so you know where you stand.

TR19 inspection in Northolt: the local picture
Food Standards Agency records include about 24 bars, pubs and nightclubs within 1.5 miles or so of the middle of Northolt. Breakfasts, bar meals and functions all put grease into the extract wherever they’re cooked. Northolt sits within the area of 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. In Northolt, food businesses are inspected by environmental health officers from Ealing council. A greasy canopy or dripping filters are the sort of thing an inspection can pick up. A TR19® certificate and photo report after each clean gives you a record to show an inspector.
School kitchens, at schools like Willow Tree Primary School for example, are typically cleaned in the holidays so no lunches are lost. Healthcare kitchens cannot easily close, so their extracts are cleaned overnight or between meal services; the nearest hospital to Northolt is Clementine Churchill Hospital, about 2 miles north-east. Church and community hall kitchens, near St Richard's Church or anywhere around Northolt, are easy to forget, but their extracts collect grease like any other.

What your team can do, and what needs us
If your staff spot something between visits, such as dripping grease, a noisy fan, a smell or a filter that will not come clean, they should report it rather than try to fix it. We can diagnose it and quote.
In-house cleaning and specialist cleaning do different jobs. A daily filter wipe and a weekly filter wash keep grease down at the front of the system, but grease that has passed the filters is out of reach. Reaching it takes a specialist with the right equipment.
Aftercare tips
Aftercare is simple, and it helps at the next visit:
- Keep the route to access panels clear
- Keep grease filters clean and fitted properly
- Report grease dripping from the canopy
- Send TR19 audit reports to your insurer on request
If any reading is 500 microns or more, the report flags it for immediate spot cleaning, and we can arrange it.
Revisit the cleaning interval whenever the menu or hours change. Fresh readings show whether it needs to change.
When it’s something else
We’ll always give you a straight diagnosis, so here’s what this work cannot put right:
- Installation problems, which fall under design guidance such as DW172
- The responsible person’s own fire risk assessment
- Hidden runs that need access panels first
Not sure which it is? You can ring 0345 646 2711, or send details by email and we will tell you honestly before booking.
