We cover South Norwood for TR19 inspection. Out-of-hours visits, a fixed quote and a written report with pictures on every job.
- An insurer’s request for a TR19 audit

The process
Our technicians bring everything the work needs, from protective sheeting to tools and access equipment. You only need to give us clear access and switch off what needs to be off. On site, the work takes an hour or two for a single kitchen, longer for a large or complex system. Getting kit into a London building takes planning, so let us know where we can load and park in South Norwood.
- 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.
- We report the findings and flag any areas that need more work.
Preparing for the visit
- Allow time for equipment near the work to be turned off and cool down
- Have your last certificate or report to hand
- Let us know about permits to work or site inductions
Getting a quote
Every quote begins with a look at the system, either from photos and details you send or from a site visit. After that, you get a fixed price for the work, before we start.

TR19 inspection in South Norwood, done properly
A grease test measures how thick the grease is inside a kitchen extract system. We use the Wet Film Thickness Test (WFTT) or the Deposit Thickness Test (DTT), taking readings at set points. From the numbers, you can see whether cleaning is due. If you have kitchen extract systems with no recent grease readings and extracts that may be over the 200 micron mean, we can help.
London kitchens tend to trade late and open early, so work in South Norwood is normally booked for the night or the early hours. Before the clean, we agree loading, parking and roof access with whoever manages the building.
Think of the report as the system’s health record: dated, with photos, and showing what was done. For TR19® Grease cleans, the certificate comes through the BESCA Vent Hygiene Elite portal and sits alongside the report.

What the work involves, part by part
Extract fan and discharge
A greasy fan works harder and wears faster. Readings show if it needs attention before the next clean.
Schools, hospitals and care homes
Hospital and care home kitchens can cook all day, every day. Readings show if cleaning is frequent enough.
Why act early in South Norwood
If a kitchen in South Norwood 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. London buildings are shared, so a fire or failure in one system can reach the neighbours above and beside you.
Leaving it longer rarely makes the work cheaper. Problems in a system tend to grow, which can make the next visit longer. If you are unsure, ring 0345 646 2711 or email us for straight advice and a fixed quote.

TR19 inspection around South Norwood
Look up South Norwood on the FSA’s food hygiene register and you will find about 238 restaurants, cafés and works canteens and about 182 takeaways in South Norwood and the streets around it, up to about 1.5 miles out. A WFTT or DTT reading tells each of those kitchens whether its grease is staying under the 200-micron mean. Most London extract cleaning happens at night, after the last service. Environmental health officers from Croydon council inspect food businesses in South Norwood. The cleanliness of the kitchen and its equipment, extraction included, is part of what they check. Before-and-after pictures from each clean are a simple way to show the extract is in hand.
A kitchen near Norwood Junction station that serves breakfast and dinner can run its extract twelve hours or more, which shortens the cleaning interval. Bursars and site managers at schools such as St Mark's Church of England Primary Academy tend to book extract cleaning for when the kitchen is empty.

South Norwood: your questions answered
Which environmental health team covers South Norwood?
Food hygiene inspections in South Norwood are carried out by Croydon council. How often a business is inspected depends on the risk rating the council gives it, so it’s worth staying ready all year.
How do you handle parking and loading in South Norwood?
London parking can be tight, so details of loading bays and permits help. If the building has a loading slot system, we’ll book into it.
How often should a kitchen extract be inspected?
Each report recommends when to test and clean next, taking the readings and the kitchen’s hours into account. A risk assessment based on measured grease should set the interval.
Are you accredited?
We’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we’re fully insured.
What’s TR19?
TR19® is the BESA specification for keeping ventilation systems clean. TR19® Grease, a standalone specification since 2019, covers grease in kitchen extract systems, while TR19® Air covers other supply and extract ductwork.
Do you have a 24/7 line?
Yes, 24/7. Office hours are Monday to Friday, 8am to 6pm, with the emergency line covering every other hour.
How far ahead should we book?
That depends on the slot you want and the size of the job. Tell us your preferred dates when you ask for a quote, and if it’s an emergency, call us any time.
Where does the waste go?
We contain it and take it with us. We collect grease, debris and waste water as we go rather than letting it spread.

Fixed quotes for TR19 inspection in South Norwood
Before we fix a price, we need to know a few things. We look at:
- Travel, parking and unloading
- Working hours and out-of-hours timing
- Site requirements such as sign-in and permits
- The scale of the work
The price reflects the work, not guesswork. That’s why every job is surveyed first, and the price is agreed before any work starts.
Helping us quote
When you contact us, it’s useful to have:
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
- Your last certificate, test record or report
- Where the plant sits or the system leaves the building, such as a roof or outside wall
- The postcode and the type of business
For TR19 inspection in South Norwood, call us on 0345 646 2711 or send us an email. Let us know the site type and the opening hours, and send photos or your last report if you can. We normally send a fixed quote within one working day.
What TR19 inspection cannot fix
To be straight with you, there are a few things this work will not fix:
- Mechanical faults in the extract
- Installation problems, which fall under design guidance such as DW172
- Removing the grease, which is a separate clean
If in doubt, call us on 0345 646 2711, or email photos and we will say what we think before booking.
Parts of the system we cover
- Wet film thickness tests
- Pre-clean surveys
- Post-clean checks
- Insurer audits
- Access surveys
- Deposit thickness tests
What your team can do, and what needs us
Some jobs should never be done in-house: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease need training, the right equipment and safe access. That is our job.
Good housekeeping makes our visits easier, not unnecessary. Regular in-house cleaning slows the build-up, but the parts you can’t see still need a specialist at the right interval.
Do you need TR19 inspection in South Norwood?
Records can go missing when a business changes hands or contractors. With no history, the current state of the extract is a guess.
Clients normally contact us when they notice one of these:
- Systems that need surveying before cleaning
- Sites with gaps in their extract records
- Missing access panels found on survey
- Ductwork where grease may be over the TR19 limits
If you run catering at a healthcare site, such as a hospital like Croydon University Hospital about 1.7 miles south-west, the extract may need cleaning more often than a part-time kitchen.
Before booking anyone
- Proof of accreditation you can verify
- Whether they’re fully insured
- Exactly which parts of the system are covered
- When they can work, and whether that is outside your opening hours
