About our TR19 inspection in Sutton
Grease thickness testing tells you how much grease is sitting in the canopy, ducts and fan. We use the Wet Film Thickness Test (WFTT) or the Deposit Thickness Test (DTT), taking readings at set points. The results show whether the system needs cleaning and how soon. The work covers insurer audits, deposit thickness tests and post-clean checks, and the jobs we see most are parts of the system left out of past cleans and extracts that may be over the 200 micron mean.
In London, few kitchens can spare a day to close, so work in Sutton 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.
The report is your system’s health record: dated, with pictures, and showing what was done. Grease extract cleans are also certificated to TR19® Grease through the BESCA VHE portal, ready for your insurer.

How we price TR19 inspection
Your quote is based on your site. We consider:
- The scale of the work
- Access, including roofs, risers and ceiling voids
- How many systems or sites are involved
- One-off work versus a regular cycle
One small site or a whole estate, we price it on the same basis: the work involved, the access and the timing. The price is fixed before we start.
Helping us quote
When you contact us, these details help:
- Any previous report or certificate
- Your opening hours and when the area is out of use
- Close-ups of filters, grilles, hatches or access panels
- Photos showing the whole system and its surroundings
The quickest way to a quote is to send photos: the system from a couple of angles, plus any access panels or hatches. Tell us what kind of site it is and when it’s open, and many jobs can be priced from that alone.
Sutton kitchens: local notes
The FSA’s food hygiene register includes about 33 bars, pubs and nightclubs across Sutton and its immediate surroundings (about a mile and a half). 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. Fire safety in Sutton falls to 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.
If you cook for passing trade around Sutton (London) station, the extract can be cleaned between your last and first customer. A hospital like St Helier Hospital, about 1.1 miles north-east, is the kind of site where a kitchen may cook for patients, staff and visitors all day.
Sutton is about 9 miles south of Kensington, in Greater London. Every kind of commercial site in Sutton, we can take on TR19 inspection. Visits can be booked for evenings, overnight or weekends so the site keeps running. Across Greater London, we cover 764 places, and Sutton is one of them. You can also see our page for London, roughly 10 miles from Sutton.
TR19 inspection in SM1, SM2, SM3 and SM7 is surveyed, quoted and booked the same way as anywhere else. If you need TR19 inspection at premises on High Street, Manor Place and St Nicholas Way or a nearby road, we can help. You’ll find Sutton on the B2230, so it’s easy for us to get to for out-of-hours visits. Neighbouring places we cover for TR19 inspection include Benhilton (1 mile north), Carshalton (1 mile east), Shanklin Village (1 mile south), St Helier (1 mile north) and Rosehill (1 mile north).

The countryside around Sutton includes Devonshire Avenue Nature Area and Duppas Hill.
Do you need TR19 inspection in Sutton?
Looking at a canopy tells you little about what’s in the duct. A system can look clean at the filters and be heavily coated further in, which is why readings matter.
The symptoms we are asked about most include:
- Cleaning intervals that may not suit the kitchen
- Sites with gaps in their extract records
- Parts of the system left out of past cleans
- Systems cleaned on a calendar with no measurements
Term dates shape school work: for a school like Robin Hood Junior School, an extract clean fits neatly into a half-term or summer break.
What your quote should include
- Which accreditations they hold, and whether you can check them
- What records you will receive afterwards
- Whether the figure could change on the day
- What happens if part of the system can’t be accessed
Between visits
After the visit, a few habits help the work last:
- Book the next test on the date in the report
- Never cook with filters missing
- Keep access panels clear and unpainted
- Keep TR19 certificates, readings and reports together
Any access problems we found are listed with a suggested fix. With panels fitted, the next clean can cover every section.
Regular grease readings keep the cleaning interval honest. It shows if build-up is speeding up.
Questions from Sutton
Who would carry out a food hygiene inspection at a kitchen in Sutton?
Kitchens in Sutton are inspected by Sutton council’s environmental health officers. An officer may look up into the canopy, so clean filters on the day and a recent certificate on file both help.
Can you come to Sutton after we close?
Yes, we can come after you close and finish before you open. It means the site in Sutton keeps running as normal. Your opening times are the first thing we ask for.
How do you keep the site clean during the work?
With sheeting and covers, before anything else happens. The work is kept contained and leave the area clean.
Are you accredited?
We hold CHAS, SafeContractor and ISO 9001, and we’re a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. Vent Hygiene Elite is run by BESCA and independently audited.
What’s TR19?
BESA’s ventilation hygiene specification in two main parts: TR19® Grease for kitchen extract systems and TR19® Air for general ventilation. It is not law, but it’s the benchmark.
Can you verify a clean after it’s been done?
It’s an inspection after cleaning, to show what state the system was left in, whoever did the clean.
How much notice should we give?
For planned work, earlier is better, particularly if your next visit is nearly due. For emergencies, we take calls 24/7.
How much does TR19 inspection cost in Sutton?
We do not 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 work begins.

Other services in Sutton
Multi-site and managed buildings
We also work for facilities teams across offices, schools and healthcare in Sutton and across Greater London. Work can be phased by floor, building or site around the people who use them.
We work for landlords, managing agents and facilities managers as well as the people running the site. Shared systems, like a riser serving several units, need a clear agreement on who books the work, and we can quote for the whole system.
How the visit works
We turn up at the time agreed with you, often in the evening, overnight or at the weekend so the site keeps working. Anything that needs to be off for the work is switched off and left to cool before any work starts, and floors and nearby surfaces are sheeted. On site, it takes around an hour or two per canopy and duct system. If your building in Sutton has sign-in rules, permits or key holders, mention them when you book.
- We go through any past certificates and reports.
- We follow the extract from canopy to discharge.
- We note where access panels are and where more are needed.
- Grease readings are taken and pictures recorded.
- You get a report and a fixed quote for the clean.
Preparing for the visit
- Mention any sign-in, permit or induction we need
- Arrange a key holder or contact on site
- Clear loose items from the work area

Photos are enough for some jobs, while others need a look on site. Big or complicated sites, and systems that are hard to see in photos, get a survey first. Either way, you get a fixed price before work begins.

What staff can safely do
In-house cleaning and specialist cleaning do different jobs. Wiping filters daily and washing them weekly keeps the visible parts in order, but grease that has passed the filters is out of reach. That part needs specialist access and equipment.
Staff cleaning does not replace a specialist visit; it supports it. Regular in-house cleaning slows the build-up, but the parts you can’t see still need a specialist at the right interval.
Why act early in Sutton
If there’s a fire or a claim, your insurer may ask for TR19 records. Missing records can put a claim at risk. Getting an inspection done now starts that paper trail. Leaving it on a busy London site only adds to the work.
No two sites are the same, so we price each one individually. The size of the job, how we reach it, its condition and the working hours all play a part.
