TR19 inspection in South Wimbledon
Before any clean in South Wimbledon, we survey the canopy, plenum, filters, ducts, fan and discharge. We check where the access panels are and whether every section can be reached, and record grease readings at set points. If you’re dealing with kitchen extract systems with no recent grease readings and kitchens whose menu or hours have changed, we can help, from pre-clean surveys, insurer audits and deposit thickness tests onwards.
Across London, many commercial kitchens are squeezed into basements and narrow back-of-house spaces, with extract ducts that can climb several floors to discharge at roof level. For a kitchen in South Wimbledon, that typically means a longer system to clean and more access panels to plan around.
Accreditations are easy to claim and worth checking. We are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease, and we hold CHAS, SafeContractor and ISO 9001, and we’re fully insured.

What TR19 inspection cannot fix
An honest diagnosis matters more to us than a booking, so here’s what TR19 inspection will not do:
- Installation problems, which fall under design guidance such as DW172
- Heavy deposits found on test, which still need cleaning
- Mechanical faults in the extract
If you’re not sure, just ring 0345 646 2711 or use the quote form and we’ll give you a straight answer before you book.

- Wet film thickness tests
- Insurer audits
- Access surveys
- Deposit thickness tests

Between visits
Looking after the system between visits is straightforward, and it helps at the next visit:
- Diary the next grease test and clean
- Do not box in or cover duct access panels
- Keep canopy edges and gutters wiped down
- Clean or swap grease filters as often as the kitchen needs
Keep the verification report next to the certificate it relates to. Together they show the system was cleaned and checked.
Keep all TR19 records together so the history is easy to show.

What TR19 inspection looks like in South Wimbledon
According to Food Standards Agency records, there are about 34 pubs and bars and about 7 hotels and B&Bs within roughly a mile and a half of the centre of South Wimbledon. Wherever they cook, the canopy, duct and fan collect grease just as a restaurant’s do. South Wimbledon is covered by 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. Overnight is the normal time to clean a London kitchen extract, so trading is not affected.
Healthcare kitchens, like those at hospitals such as St George's Hospital (about 1 mile north-east), often cook for long hours, which puts them in BESA’s heavier-use bands. If you cook for passing trade around Wimbledon station, the extract can be cleaned between your last and first customer.

Why it’s worth doing now in South Wimbledon
Without readings, you’re guessing when to clean. Any reading of 500 microns or more needs immediate spot cleaning under TR19® Grease, which you won’t know without measuring. London sites work long hours, and the longer a job is left, the bigger it gets.
Several systems or sites on one quote often makes better use of the time. Mention every system or site you need covered and we’ll price it together.
