TR19 inspection in Northfields
A grease test measures how thick the grease is inside a kitchen extract system. Readings are taken at set points using the Wet Film Thickness Test (WFTT) or the Deposit Thickness Test (DTT). From the numbers, you can see whether cleaning is due. Common call-outs are for kitchen extract systems with no recent grease readings and heavy grease suspected in the plenum or ducts, on access surveys, wet film thickness tests and pre-clean surveys.
In a London area like Northfields, 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, so a regular TR19® clean protects everyone in it.
Our accreditations include CHAS, SafeContractor and ISO 9001, and we’re fully insured. We are also a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, trading since 2009.

What we are called out for in Northfields
You cannot judge grease thickness by eye. A system can look clean at the filters and be heavily coated further in, which is why readings matter.
Keep an eye out for any of the following:
- Sites with gaps in their extract records
- Surveys needed before quoting a full clean
- Extracts that have never been grease tested
- Ductwork where grease may be over the TR19 limits
Historic houses near Northfields, such as Boston Manor about 0.5 miles south, are a reminder that older buildings with event kitchens can have long, awkward duct routes.
Questions to ask before booking
- What happens if part of the system can’t be accessed
- Their accreditations, such as BESCA Vent Hygiene Elite, CHAS or SafeContractor
- Whether VAT is included
- When they can work, and whether that is outside your opening hours
When something else is needed
In fairness, some problems need a different fix:
- The responsible person’s own fire risk assessment
- A faulty or failing extract fan
- The grease itself, which needs a full or spot clean
Not sure which it is? You can call us on 0345 646 2711 or email us and we will tell you honestly.

Landlords, agents and facilities managers
Where a tenant occupies the premises but the landlord owns the building, it’s worth checking the lease for who maintains the systems. We can quote either party, and the report can go to both.
We regularly work with managing agents. Send the address, what’s needed and how access works and we’ll come back with a fixed quote.
What happens on the day
When we arrive, we check the system against the survey or the photos you sent. If anything is different, we talk it through with the person on site before carrying on. After that, the work takes a couple of hours for a typical kitchen extract system. Managed blocks in London often need contractors booked in ahead, and we are happy to deal with the agent directly for a site in Northfields.
- The visit is arranged for when the kitchen is not busy.
- The system is checked from canopy to discharge.
- We take WFTT or DTT readings at set points along the system.
- We photograph the test points and record any sections we can’t reach.
- You get a report with readings, pictures and recommendations.
How to prepare
- Tell us the best time to work, such as after service or at a weekend
- Allow time for equipment near the work to be turned off and cool down
- Make sure someone can let us in and lock up afterwards

Northfields questions
Does London parking affect a job in Northfields?
We plan it in advance, so let us know about loading bays, permits and access rules at the building. Working overnight, as we often do in London, normally makes it simpler.
Which fire and rescue service is responsible for Northfields?
London Fire Brigade is the fire and rescue service for Northfields. Records of extract cleaning are a sensible thing to have ready if a fire safety officer carries out an audit.
How much notice do you need?
It depends on the time you need and how big the job is. Mention your preferred dates with your enquiry, and if it’s an emergency, call us any time.
How much does TR19 inspection cost?
We do not publish prices, because the cost 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 any work starts.
Do you work with multi-site operators?
Yes. One number covers all your sites in our area, and visits can be set on a regular cycle.
Do we have to follow TR19 by law?
No. It’s the benchmark rather than the law. Without TR19 records, an insurance claim can be reduced or refused, so it matters in practice.
What does a pre-clean survey involve?
It’s a look at the whole extract before it’s cleaned, with readings and photos. We can work from pictures and details, or visit, whichever suits the system.
What do you need from me for a quote?
The site address, the type of premises and your opening hours, plus photos of the system and your last certificate or report if you have one.
What staff can safely do
Staff cleaning and specialist work aren’t the same thing. Wiping filters daily and washing them weekly keeps the visible parts in order, but they don’t reach the grease that builds up further in. That part needs specialist access and equipment.
Logging matters as much as cleaning. A simple log of filter washes, wipe-downs and checks helps show that the system is managed between specialist visits, alongside our reports.

What affects the quote in Northfields
The quote reflects the site in front of us. We take into account:
- One-off work versus a regular cycle
- The scale of the work
- The number of sites or systems
- The condition of the system
One small site or a whole estate, we price it on the same basis: what needs doing, how we get to it and when. You’ll have a fixed price before we start.
Helping us quote
When you call or email, it’s useful to have:
- How we’d reach plant on a roof or in a plant room
- Problems your staff have spotted
- The paperwork from the last visit, if you have it
- Detail shots of panels, filters and grilles
Getting a quote does not take long. Call or email with a few details and you will typically have a fixed price within one working day. If we need to see the system first, we book a survey around your hours.
TR19 inspection in Northfields: the local picture
The FSA’s food hygiene register includes about 87 pubs, bars and clubs and about 13 hotels and guest houses in and around Northfields, up to about a mile and a half out. Breakfasts, bar meals and functions all put grease into the extract wherever they’re cooked. Night work suits London kitchens, and roads and loading bays tend to be quieter too. In Northfields, food businesses are inspected by environmental health officers from Ealing council. An officer looking round a kitchen will see the canopy, and grease there is hard to miss. Before-and-after pictures from each clean are a simple way to show the extract is in hand.
If you run catering at a healthcare site, such as a hospital like Ealing Hospital about 1.4 miles west, the extract may need cleaning more often than a part-time kitchen. School kitchens, at schools like Mount Carmel Catholic Primary School for example, are normally cleaned in the holidays so no lunches are lost.

Looking after it afterwards
After the visit, a few habits help the work last:
- Mention new equipment or longer hours at the next test
- Never cook with filters missing
- Don’t box in or cover duct access panels
- Have the latest report ready for insurance renewals
For an insurer audit, send them the report as it is, with readings, pictures and any areas not accessible.
Fit access panels where the survey finds sections can’t be reached, so every part of the duct can be cleaned.
