TR19 inspection in West Drayton, 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. The results show whether the system needs cleaning and how soon. If you have sites with gaps in their extract records and missing access panels found on survey, we can help, from deposit thickness tests, post-clean checks and access surveys onwards.
London kitchens tend to trade late and open early, so work in West Drayton 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.
Duct Doctor has been trading since 2009, and we are a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. CHAS, SafeContractor and ISO 9001 are in place too, and we carry full insurance.

When to call us in West Drayton
Records can go missing when a business changes hands or contractors. Without them, nobody knows how much grease is in the system or when it was last cleaned.
Most sites get in touch when they notice one of these:
- Parts of the system left out of past cleans
- Systems that need surveying before cleaning
- Kitchens taken over with no cleaning records
- Post-clean verification after another contractor’s clean
Where a hall near Church of St Martin, or anywhere in West Drayton, hosts lunch clubs or events, its extract gathers grease just as a café’s does.
Before you book anyone
- Whether the price is fixed
- How areas they can’t reach will be recorded

West Drayton kitchens: local notes
The FSA’s data shows about 14 pubs and bars and about 8 hotels and guest houses registered in West Drayton and the streets around it, up to about 1.5 miles out. Wherever they cook, the canopy, duct and fan collect grease just as a restaurant’s do. West Drayton is covered by London Fire Brigade. Its fire safety officers can audit commercial kitchens, and grease in the extract is part of a kitchen’s fire risk. It’s Hillingdon council that sends environmental health officers to food businesses in West Drayton. Extraction counts as kitchen equipment, so its condition can come up on the day. A TR19® certificate and photo report after each clean gives you a record to show an inspector.
Term dates shape school work: for a school like West Drayton Academy, an extract clean fits neatly into a half-term or summer break. If you run a café or takeaway near West Drayton station, early starts and late finishes leave little time to clean, so overnight extract cleaning suits.

What affects the cost of TR19 inspection
There’s no set price list, because sites vary so much. What we look at:
- Site rules, permits and inductions
- Whether several sites go on one quote
- Parking and loading at the site
- Whether it’s a one-off visit or part of a schedule
The cost depends on the size of the system, the condition it’s in and access to every part of it. You get a fixed price before work begins, so you know where you stand.

What happens if it’s left?
An EHO visit, an insurance renewal or a fire risk assessment is a bad time to find your extract records are thin. A recent inspection report means you are ready when asked. It’s better booked as a planned job in West Drayton than handled as an emergency.
A single site or a whole portfolio, the quote is built the same way: what needs doing, how we get to it and when. You’ll have a fixed price before we start.

How it works
Our technicians bring everything the work needs, from protective sheeting to tools and access equipment. All we need from you is clear access and the right equipment switched off. On site, the work takes anything from an hour for a small canopy and short duct to a good part of a day for a large site. Loading bays, visitor permits and roof access are the first things we ask about for a site in West Drayton.
- 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.
- The results are reported, with anything missed flagged.
Preparing for the visit
- Let us know about parking and loading
- Dig out any earlier paperwork for the system
- Let us know about permits to work or site inductions

Advice
West Drayton questions
Can you work in West Drayton outside opening hours?
Yes. We work evenings, overnight and at weekends. That way a site in West Drayton does not have to lose a day’s trading. Just call 0345 646 2711 or send us an email with your opening times and we will plan around them.
Do you do school kitchen extract cleaning in West Drayton in the summer holidays?
Yes, out-of-term visits are normal for schools. There are about 23 schools, colleges and universities on the FSA’s food hygiene register within about 1.5 miles of West Drayton. You can phone us on 0345 646 2711 or email us with the dates the site is empty.
Do you work in West Drayton?
Yes. We cover West Drayton and the rest of Greater London, within our South East and London area. For a fixed quote, ring 0345 646 2711, or send details by email.
Why survey before a clean?
We check the layout, the grease levels and the access, so the clean goes to plan. Missing access panels are noted ahead of the clean.
Do you check other contractors’ cleans?
A post-clean check records grease readings and photos after the work, for our cleans and other firms’ alike.
What does TR19 inspection cost?
There’s no set price, as it depends on the job: how big it is, what state it’s in, how we reach it and the working hours. You get a fixed price before any work starts.
What is a WFTT or DTT grease test?
It’s a measurement of how much grease is coating the inside of the extract, by WFTT or DTT. The results are given in microns.
Will you produce a report for our insurer?
Yes. We inspect the system and produce a report with grease readings, photos and any inaccessible areas. You can pass it straight to your insurer or broker.
Honest limits
We will always give you a straight diagnosis, so here’s what this work cannot put right:
- Mechanical faults in the extract
- Sections with no access, until panels are fitted
- The legal duty, which stays with the responsible person
Not sure which it is? You can ring 0345 646 2711 or email us and we will tell you honestly.
What the work covers
- Insurer audits
- Post-clean checks
- Pre-clean surveys
- Wet film thickness tests
- Access surveys
- Deposit thickness tests
Aftercare tips
So the system stays in good health:
- Have the latest report ready for insurance renewals
- Flag changes in how much frying the kitchen does
- Diary the next grease test and clean
- Keep access panels clear and unpainted
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 every part of the duct can be cleaned.
Staff cleaning versus specialist work
Your own staff can handle the daily basics: wiping down canopy surfaces, cleaning filters and keeping a simple log. Inside the ducts, risers and fan is specialist work, which is where we come in.
When your team notices a problem between visits, such as dripping grease, a noisy fan, a smell or a filter that won’t come clean, it’s best reported rather than tackled in-house. We can diagnose it and quote.
