Greater London · TR19 inspections and grease testing
TR19 Inspection in Heston
We cover Heston for TR19 inspections and grease testing. Fixed quotes, work around your opening hours and photo reports on every job.
- An insurer’s request for a TR19 audit
- Sections of duct that can’t be reached
- Kitchens taken over with no cleaning records
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. An inspection now gives a site in Heston a current picture. For a site in Heston, fitting the work in overnight now is far easier than closing at short notice later.
The cost depends on the size of the system, the condition it’s in and how easy it is to reach. You get a fixed price before we start, so you know where you stand.
What you get with us
- CHAS, SafeContractor and ISO 9001

TR19 inspection in Heston, done properly
Not every kitchen fits neatly into a calendar. In a busy kitchen, grease can build faster than the minimum intervals allow for, which is why measurement matters. We give your risk assessment measured figures rather than guesses. We’re often asked to deal with surveys needed before quoting a full clean and missing access panels found on survey, across post-clean checks, insurer audits and deposit thickness tests.
London kitchens tend to trade late and open early, so extract cleaning in Heston is typically done overnight, after the last service. Before the clean, we agree loading, parking and roof access with whoever manages the building.
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 are fully insured.

In-house cleaning or a specialist?
Keep a record of what your team does. A dated log of in-house cleaning and checks helps show that the system is managed between specialist visits, next to our reports.
When your team notices a problem between visits, such as dripping grease, a noisy fan, a smell or a filter that will not come clean, it’s best reported rather than tackled in-house. We’ll take a look and send you a fixed quote.
Fixed quotes for TR19 inspection in Heston
The diagnosis comes before the price. The main factors are:
- Whether we need access equipment or extra panels
- Parking and loading at the site
- The times the site is available
- Site rules, permits and inductions
We don’t list prices on the website, because the cost depends on the site in front of us. For a fixed quote, ring 0345 646 2711 or use the quote form, and we’ll explain what it covers.
What we need to know
A few details help us quote accurately. When you get in touch, it helps to send:
- Problems your staff have spotted
- Any access panels or hatches you can see
- The roof, plant room or outside wall the system runs to
- Your last certificate, test record or report
Some systems can be priced from photos; others need a survey. Big or complicated sites, and systems that are hard to see in pictures, get a survey first. Either way, you get a fixed price before work begins.
Managing agents and facilities teams in Heston
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.
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.
Common problems we fix in Heston
As hot, greasy air travels up the duct, it cools and leaves a film behind. The thickest layers can sit out of sight in the plenum, at bends and along flat runs.
If you notice any of these, it’s worth a diagnosis:
- Confirming a clean reached the whole system
- Missing access panels found on survey
- Cleaning intervals that may not suit the kitchen
- Insurers asking for TR19 evidence
If you run catering at a healthcare site, such as a hospital like Hounslow Hospital about 1.2 miles south, the extract may need cleaning more often than a part-time kitchen.

TR19 inspection in Heston: the local picture
Look up Heston on the FSA’s food hygiene register and you’ll find about 275 restaurants, cafés and works canteens and about 124 sandwich bars and takeaways in Heston and the streets around it, up to about 1.5 miles out. Each kitchen extract among them can be measured for grease to set the right cleaning interval. In Heston, food businesses are inspected by environmental health officers from Hounslow council. The cleanliness of the kitchen and its equipment, extraction included, is part of what they check. Keeping each certificate and photo report on file helps show the extract is looked after. Heston sits within the area of 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.
Bursars and site managers at schools such as Westbrook Primary School tend to book extract cleaning for when the kitchen is empty. If you run catering at a historic house or estate in the area (Osterley House is about 1.2 miles east), event kitchens in older buildings often have awkward duct runs that need planning.
Heston is about 2 miles south of Southall, in Greater London. Across the TW5 area, we can carry out TR19 inspection at your premises. Heston is one of 764 towns, villages and districts in Greater London where we work for commercial clients. We also work in London, about 12 miles from Heston.
Work in TW5, UB2 and TW3 is surveyed, quoted and booked the same way as anywhere else. If you need TR19 inspection at premises on Fern Lane, Sutton Road and Eton Avenue or anywhere close by, our technicians can take on the work.

How the visit works
Everything the job needs comes with us, including protection sheets, the right tools and access kit. You only need to give us clear access and switch off what needs to be off. The visit takes an hour or two for a single kitchen, longer for a large or complex system. For a job in Heston, tell us about loading bays, permits, lifts and roof access when you book.
- We go through any past certificates and reports.
- The layout is traced from the canopy to the discharge.
- We note where access panels are and where more are needed.
- We measure the grease and photograph each point.
- You get a report and a fixed quote for the clean.
Before we arrive
- Mention any locked doors, roof access or ceiling voids
- Arrange a key holder or contact on site
- Have your last certificate or report to hand
How to get a quote
There’s no standard price list, because no two systems are the same. Instead, we look at your site first, from photos or a survey, then send a fixed quote. To start, phone us on 0345 646 2711, or email photos.
Advice
Aftercare tips
Think of this as the after-treatment advice, in brief:
- Wipe the canopy surfaces regularly
- Have the latest report ready for insurance renewals
- Report grease dripping from the canopy
- Flag changes in how much frying the kitchen does
The report recommends when the system should next be cleaned and tested, from the measured grease and the kitchen’s hours.
Keep all TR19 records together so the history is easy to show.
Heston questions
Can a school canteen extract in Heston be done out of term time?
Yes, holiday work suits schools best. Around Heston, the Food Standards Agency lists about 37 schools and colleges with registered kitchens within a mile and a half or so. Send us your term dates when you call 0345 646 2711, or send details by email, and we will fit the work in.
Can the work in Heston be done at night or at weekends?
Yes, evening, overnight and weekend work is normal for us. It means the site in Heston keeps running as normal. When you phone us on 0345 646 2711 or send us an email, mention when the site is quiet.
What is TR19?
It’s the industry benchmark for cleaning ventilation and kitchen extract systems, written by BESA. It covers how systems are inspected, cleaned and checked, and it takes a risk-based approach.
Do we have to follow TR19 by law?
No, not in itself. The Fire Safety Order 2005 still requires the responsible person to manage fire risk, which in a kitchen includes grease in the extract. Many insurance policies also require TR19 adherence.
Can you verify a clean after it’s been done?
After a clean, we take new readings and pictures to show how the system was left. It can follow our own cleans or another contractor’s.
How do you protect the area?
We cover floors and nearby surfaces with sheeting before any work starts, and anything we remove is contained. At the end, the area is cleaned down.
How much does TR19 inspection cost?
Every site is different, so each gets its own fixed quote. For a quote, phone us on 0345 646 2711, or email photos and tell us about the site and its opening hours.
How do you measure grease in a kitchen extract?
We measure the grease at set points with a WFTT or DTT test, and set against the TR19® Grease figures.
