Greater London · TR19 inspections and grease testing
TR19 inspections and grease testing in Yiewsley, Greater London
We cover Yiewsley for TR19 inspections, grease thickness testing, pre-clean surveys and post-clean verification. Fixed quotes, work around your opening hours and photo reports on every job.
- Heavy grease suspected in the plenum or ducts
- Confirming a clean reached the whole system
- Missing TR19 certificates or history
When to call us in Yiewsley
You can’t judge grease thickness by eye. Clean filters can hide a heavy layer behind them, which is why readings matter.
What we are most often called out for:
- Missing TR19 certificates or history
- Insurers asking for TR19 evidence
- Cleaning intervals that may not suit the kitchen
- Pre-clean surveys before a first TR19 clean
Older buildings often hide long, awkward duct runs, and if you run a kitchen at a historic venue in the area (Northolt Manor is about 1.4 miles north-east), access may need planning.
What to look for in a quote
- Proof of accreditation you can verify
- If the quote is a fixed price or an estimate
- Whether the work can be done while the site is closed
- How they set the interval to the next visit
TR19 inspection in Yiewsley, done properly
BESA sets minimum cleaning intervals by daily use: heavy use (12 to 16 hours a day) every 3 months, moderate use (6 to 12 hours) every 6 months and light use (2 to 6 hours) every 12 months. Grease testing shows whether your kitchen needs cleaning more often than that. If you have sites with gaps in their extract records and checking the result of a recent clean, we can put it right, from access surveys, deposit thickness tests and wet film thickness tests onwards.
In a London area like Yiewsley, 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 are fully insured. We’re also a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we have been trading since 2009.

Looking after it afterwards
Simple habits between visits make a real difference. Our advice:
- Book the next test on the date in the report
- Look out for grease drips round the canopy edge
- Have the latest report ready for insurance renewals
- Do not box in or cover duct access panels
The report recommends when the system should next be cleaned and tested, based on the readings and how the kitchen is used.
Fit access panels where the survey finds sections cannot be reached, so grease is not left building in hidden parts.
What TR19 inspection looks like in Yiewsley
The Food Standards Agency lists about 18 bars, pubs and nightclubs as registered food businesses in and around Yiewsley, up to about a mile and a half out. Wherever they cook, the canopy, duct and fan collect grease just as a restaurant’s do. Kitchens in Yiewsley get their food hygiene inspections from Ealing council. An officer looking round a kitchen will see the canopy, and grease there is hard to miss. Keeping each certificate and photo report on file helps show the extract is looked after. Overnight is the normal time to clean a London kitchen extract, so trading is not affected.
If you run a church or community hall kitchen, near St Joseph the Worker & Dovetail Centre or elsewhere in Yiewsley, its extract still collects grease from every lunch and event. A hospital like Hayes Cottage Hospital, about 1.5 miles south-west, is the kind of site where a kitchen may cook for patients, staff and visitors all day.
Yiewsley is about 2 miles north-east of Hayes, in Greater London. Whatever kind of site you run in Yiewsley, TR19 inspection is something we can help with.

Part by part
Restaurants, pubs and hotels
We test between services, early in the morning or after close so trading isn’t affected.
Extract fan and discharge
Grease builds up on the fan blades and inside the housing. We check and test them as part of the inspection.
Managing agents and facilities teams in Yiewsley
We work for landlords, managing agents and facilities managers as well as the people running the site. Where a system serves more than one tenant, such as a shared riser, it helps to agree who arranges the work, and we can quote for the whole system.
When the building owner and the occupier are different, the lease normally sets out who maintains what. We can quote either party, and the report can go to both.
How it works
Before we leave, we walk the area with whoever is on site. Anything we couldn’t reach or that needs attention is pointed out there and then, and it goes on the report too. All told, the work takes an hour or two for a single kitchen, longer for a large or complex system. Most London sites can’t stop for the day, so work in Yiewsley is normally done overnight, early in the morning or at weekends.
- After the clean, we arrange a time to check the system.
- The same access points are opened up.
- Grease readings are taken again at set points.
- We photograph each area to record how it was left.
- We report the findings and flag any areas that need more work.
Before we arrive
- Let us know when the site is closed or quiet
- Allow time for equipment near the work to be turned off and cool down
- Arrange a key holder or contact on site
Ask for a quote
Quoting starts with a diagnosis, either from pictures and details you send or from a site visit. After that, you get a fixed price for the work so you know the cost before any work starts.

What affects the cost of TR19 inspection
You will get a fixed price before work begins. It takes into account:
- When the work can happen, such as evenings, overnight or weekends
- The number of sites or systems
- How big the system is
- Any permits to work or inductions
Every site is different, 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.
Asking for a quote
To speed up the quote, send us:
- The roof, plant room or outside wall the system runs to
- Your last certificate, test record or report
- A few general shots of the system
- Any access panels or hatches you can see
Quotes are quick. Send a few details and photos, and we typically reply with a fixed quote within one working day. Where a survey is needed, we arrange a time that suits the site.
Honest limits
TR19 inspection cannot fix everything, and we’d rather say so up front. It will not put right:
- Sections with no access, until panels are fitted
- The grease itself, which needs a full or spot clean
- Ductwork that was designed or installed badly
If you are not sure, just call 0345 646 2711 or drop us a line and we’ll give you a straight answer.
