TR19 inspection in Cranham
Before any clean in Cranham, we survey the canopy, plenum, filters, ducts, fan and discharge. Access is checked along the full length, and grease readings are taken at set points. If you have insurers asking for TR19 evidence and pre-clean surveys before a first TR19 clean, we can help.
Kitchens in Cranham, like many across London, can share a building with flats or offices, with the duct running up through shared risers. A duct fire there can reach parts of the building far from the range, which is why keeping it clean to TR19® matters.
It’s worth checking any contractor’s accreditations. We’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we hold CHAS, SafeContractor and ISO 9001, with full insurance on top.

What the work involves, part by part
Extract fan and discharge
The discharge at the end of the system is checked as well, as grease can build up there too.
Schools, hospitals and care homes
School and college kitchens still need their extract checked. Testing shows whether the interval suits.
What a clean won’t put right
Before you book, it helps to know what’s not included:
- Design faults in the extract system
- Hidden runs that need access panels first
- The legal duty, which stays with the responsible person
Not sure which it is? You can call 0345 646 2711 or email us and we’ll tell you honestly.

Cranham: your questions answered
Do you work at weekends in Cranham?
Yes. We work evenings, overnight and at weekends. Your customers, staff or residents in Cranham needn’t be disturbed. Your opening times are the first thing we ask for.
Is parking a problem for work in Cranham?
A loading bay, a visitor permit or off-street space near the site in Cranham makes the visit easier to plan. Working overnight, as we often do in London, typically makes it simpler.
Do you offer maintenance contracts?
Yes. We run scheduled maintenance contracts, set at the interval the system needs. Each report recommends when the next visit should be.
How do you keep the site clean during the work?
By covering it before any work starts. We keep the work contained and clean down when we finish.
Which kinds of sites do you work on?
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.
Will you produce a report for our insurer?
Yes. We inspect the system and produce a report with grease readings, photos and any inaccessible areas. You can pass it straight to your insurer or broker.
What happens on a pre-clean survey?
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 so they can be sorted first.
Do you have a 24/7 line?
Yes. Our emergency line runs 24/7, for problems that can’t wait. Ring any time and tell us what’s happened.
When to call us in Cranham
Grease in a duct is flammable fuel. A flare-up on the range can be drawn into the canopy and duct, and from there a fire can spread through the ductwork. Knowing how much there is lets you act before it becomes a hazard.
What we’re most often called out for:
- Systems cleaned on a calendar with no measurements
- Uncertainty over how often to clean
- Missing TR19 certificates or history
- An insurer’s request for a TR19 audit
For kitchens close to Upminster station, where the day often starts early and ends late, the extract can be cleaned overnight.

In-house cleaning or a specialist?
Away from the kitchen, the in-house job is mainly checking: keeping grilles clear, noting unusual noise or smells and logging filter changes. The inside of ducts and units needs a specialist.
Staff cleaning does not 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.

What else we do in Cranham
How the visit works
There are three stages on the day: set-up, the treatment itself and the sign-off. Set-up means sheeting and making equipment safe, and the sign-off is a written report with pictures. The middle part takes longest, which takes a morning or less for one kitchen, more where there are several systems. A name and number for whoever controls access to the building in Cranham saves time on the night.
- Post-clean verification is booked once the clean is done.
- We open the access points used on the clean.
- We repeat the WFTT or DTT readings.
- Photos are taken to show the condition after the clean.
- The results are reported, with anything missed flagged.
Before we arrive
- Tell us about site rules, permits or sign-in
- Let us know when the site is closed or quiet
- Arrange a key holder or contact on site
How to get a quote
To help us quote: where the site is, what it is and its opening hours, photos of the system and the last certificate or report, if there is one. Once you have those, phone us on 0345 646 2711 or send us an email.
Advice
Grease, kitchens and Cranham
There are about 82 cafés, restaurants and staff canteens and about 22 takeaways across Cranham and its immediate surroundings (about a mile and a half), according to the Food Standards Agency’s register. For any of them with a canopy, measuring grease is better than guessing when to clean. Cranham sits within the area of London Fire Brigade. Its fire safety officers can audit commercial kitchens, and grease in the extract is part of a kitchen’s fire risk. Food hygiene inspections in Cranham are the job of Havering council’s environmental health team. The cleanliness of the kitchen and its equipment, extraction included, is part of what they check. A TR19® certificate and photo report after each clean gives you a record to show an inspector.
Kitchens that cook twelve hours or more a day, as some healthcare kitchens do, fall into BESA’s three-monthly minimum; St George's Hospital is the nearest hospital to Cranham, about 2.4 miles south-west. If you run a church or community hall kitchen, near St Luke's Cranham or elsewhere in Cranham, its extract still collects grease from every lunch and event.

Aftercare tips
Here’s the after-treatment advice, short and simple:
- Tell us if menus or opening hours change
- File every inspection report with your certificates
- Report grease dripping from the canopy
- Don’t box in or cover duct access panels
After the inspection, we send a report showing each reading, its location and pictures. File it alongside your TR19 certificates.
Revisit the cleaning interval whenever the menu or hours change. Fresh readings show whether it needs to change.
Why act early in Cranham
Surveying first means the clean goes to plan. Access problems are spotted in advance rather than on the night, so the clean covers the whole system. London buildings are shared, so a fire or failure in one system can reach the neighbours above and beside you.
Putting the work off seldom saves money. Problems in a system tend to grow, which can make the next visit longer. If you are not sure what’s needed, call 0345 646 2711 or send us an email for straight advice and a fixed quote.
