About our TR19 inspection in Hanworth
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. Those are minimums, and grease readings help set the real interval. If you are dealing with insurers asking for TR19 evidence and extracts that have never been grease tested, we can help, from insurer audits, wet film thickness tests and post-clean checks onwards.
London kitchens are often tucked into basements or the back of a building, with extract ducts that can climb several floors to discharge at roof level. For a kitchen in Hanworth, that typically means a longer system to clean and more access panels to plan around.
Think of the report as the system’s health record: dated, with pictures, and showing what was done. For TR19® Grease cleans, the certificate comes through the BESCA Vent Hygiene Elite portal, ready for your insurer.

Managing agents and facilities teams in Hanworth
Managing agents often deal with us directly. Tell us the site, the work and the access arrangements, and we will send a fixed quote.
The Fire Safety Order 2005 puts the duty to manage fire risk on the responsible person, which may be the employer, owner, landlord, FM or managing agent. With shared responsibility, good records help everyone.
Aftercare tips
After the visit, a few habits help the work last:
- Clean grease off the canopy between professional cleans
- Have the latest report ready for insurance renewals
- Keep grease filters clean and fitted properly
- Look out for grease drips round the canopy edge
The report recommends when the system should next be cleaned and tested, based on the readings and how the kitchen is used.
When cooking hours or the menu change, check the interval still fits. A quick grease test answers the question.
What we’re called out for in Hanworth
TR19® is the benchmark that insurers, fire officers and EHOs refer to. It is not legislation; the legal duty comes from the Fire Safety Order 2005, under which the responsible person must reduce fire risk, and grease in the extract is part of that risk.
What we’re most often called out for:
- Missing TR19 certificates or history
- Kitchen extract systems with no recent grease readings
- Uncertainty over how often to clean
- Insurance renewals needing proof of TR19 cleaning
If you run a church or community hall kitchen, near St Richard's Church or elsewhere in Hanworth, its extract still collects grease from every lunch and event.

Hanworth: your questions answered
Do you work overnight in Hanworth?
Yes, nights and weekends are routine for us. The work in Hanworth can fit around your hours. Just ring 0345 646 2711 or email us with your opening times and we’ll plan around them.
Who would carry out a food hygiene inspection at a kitchen in Hanworth?
That is Richmond-Upon-Thames council, whose environmental health officers carry out food hygiene inspections in Hanworth. How often a business is inspected depends on the risk rating the council gives it, so it’s worth staying ready all year.
Can we book visits on a schedule?
Yes. Regular plans can run on 3, 6 or 12-monthly cycles, to suit the system and how it’s used.
Is TR19 cleaning the law?
No. It’s the benchmark rather than the law. Without TR19 records, an insurance claim can be reduced or refused, so following it is the sensible course.
What grease levels does TR19 allow?
Under TR19® Grease, the mean thickness should not exceed 200 microns between cleans. Any reading of 500 microns or more needs immediate spot cleaning.
What is a WFTT or DTT grease test?
WFTT and DTT are the two methods for measuring grease thickness, in microns. Readings are taken at set points through the system.
How do you protect the area?
We start with protection: floor sheeting and covers over nearby surfaces and equipment. The area is left tidy, with our waste taken away.
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 ahead of the clean.
In-house cleaning or a specialist?
Some jobs should never be done in-house: opening up ductwork, cleaning fans, drop testing fire dampers and measuring grease call for the right kit, training and safe access. That is our job.
Staff cleaning doesn’t 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.
The process
The first job on site is protection: sheeting goes over floors and surfaces close to the work. After that, the system is made safe and the work begins. It takes a couple of hours for a typical kitchen extract system, and we clear up before we go. Before any visit in Hanworth, we agree where the van can stop and how equipment reaches the system.
- First we book a time that will not disrupt cooking.
- We look over the canopy, plenum, ducts, fan and discharge.
- We take WFTT or DTT readings at set points along the system.
- Each test point and any access problems are photographed.
- We send a report setting out the readings, photos and next steps.
Preparing for the visit
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
- Dig out any earlier paperwork for the system
- Agree a time when the area can be out of use
How to get a quote
Quotes are quick. Call or email with a few details and you’ll usually have a fixed price within one working day. If we need to see the system first, we book a survey around your hours.

What a clean won’t put right
In fairness, some problems need a different fix:
- Removing the grease, which is a separate clean
- Parts of the duct nobody can reach yet
- The responsible person’s own fire risk assessment
If in doubt, give us a ring on 0345 646 2711, or send details by email and we’ll say what we think before you book.

Kitchen extracts in Hanworth
Food Standards Agency data counts about 57 restaurants, cafés and canteens and about 25 sandwich bars and takeaways within about 1.5 miles of central Hanworth. A WFTT or DTT reading tells each of those kitchens whether its grease is staying under the 200-micron mean. Hanworth 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. In Hanworth, food businesses are inspected by environmental health officers from Richmond-Upon-Thames council. An officer looking round a kitchen will see the canopy, and grease there is hard to miss. Before-and-after pictures from each clean are a simple way to show the extract is in hand.
Healthcare kitchens cannot easily close, so their extracts are cleaned overnight or between meal services; the nearest hospital to Hanworth is Teddington Memorial Hospital, about 1.8 miles east. For schools such as Buckingham Primary School, kitchen extract cleaning is typically booked for the holidays, when the canteen is closed.

Different parts, different methods
Canopy and plenum
We look over the canopy, inside and out, with readings where grease collects.
Restaurants, pubs and hotels
BESA’s minimum for heavy use of 12 to 16 hours a day is a clean every 3 months, and readings show whether that’s enough.
