TR19 inspection for kitchens and businesses in Twickenham
Insurance policies often require evidence of TR19® cleaning and inspection. Without it, a claim can be refused or reduced. A TR19 audit sets out the system’s condition, with readings and photos, for sites in Twickenham and the rest of Greater London. The work covers post-clean checks, wet film thickness tests and access surveys, and common reasons people get in touch are systems that need surveying before cleaning and heavy grease suspected in the plenum or ducts.
London kitchens tend to trade late and open early, so work in Twickenham 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.
We’ve been trading since 2009, as a BESCA Vent Hygiene Elite member, cleaning to BESA TR19® Grease. We also hold CHAS, SafeContractor and ISO 9001, and we’re fully insured.

Between visits
Think of this as the after-treatment advice, short and simple:
- Keep canopy edges and gutters wiped down
- File every inspection report with your certificates
- Keep the route to access panels clear
- Clean or swap grease filters as often as the kitchen needs
Readings of 500 microns or more are highlighted as needing immediate spot cleaning, and we can arrange it.
Fit access panels where the survey finds sections cannot be reached, so grease is not left building in hidden parts.

Twickenham kitchens: local notes
Look up Twickenham on the FSA’s food hygiene register and you will find about 208 cafés, restaurants and staff canteens and about 39 takeaways and sandwich shops in Twickenham and the streets around it, up to about 1.5 miles out. Where they cook under a canopy, a grease reading is the way to tell whether the extract is due a clean. In Twickenham, food businesses are inspected by environmental health officers from Richmond-Upon-Thames council. Extraction counts as kitchen equipment, so its condition can come up on the day. Our report lists what was cleaned and when, which is useful to have ready. Most London extract cleaning happens at night, after the last service.
For schools such as St Richard Reynolds Catholic Primary School, kitchen extract cleaning is usually booked for the holidays, when the canteen is closed. Kitchens that cook twelve hours or more a day, as some healthcare kitchens do, fall into BESA’s three-monthly minimum; South Middlesex Hospital is the nearest hospital to Twickenham, about 0.6 miles north.
Twickenham is about 7 miles south-west of Kensington, in Greater London. Sites in Twickenham get the same service as everywhere we cover: a survey first, a fixed quote, work timed around your hours and a report with pictures. Across Greater London, we cover 764 places, and Twickenham is one of them. We also work in London, around 11 miles away.
All of TW1, TW2, TW4 and TW3 is covered for TR19 inspection, from the main roads to the quietest streets. You’ll find streets such as Station Road, London Road and Talbot Road, all of which we cover for TR19 inspection. Main roads around Twickenham include the A305 and A310, which makes travel easy for evening and night visits. We also cover the places around Twickenham: Whitton (1 mile west), Eel Pie Island (1 mile east), Strawberry Hill (1 mile south), Ivybridge (1 mile north) and Fulwell (1 mile south). We also work in nearby towns such as London (11 miles east), City of Westminster (9 miles north-east), Marylebone (10 miles north-east), Kensington (7 miles north-east), St Pancras (11 miles north-east) and Shoreditch (12 miles north-east).

For landlords and multi-site operators
Records are where multi-site compliance often slips. Each visit produces a dated report with pictures, ready to show insurers, fire officers or EHOs.
If you look after several sites, we can plan visits across the whole estate and price them together. Every building has its own written report, so records stay tidy.
What affects the cost of TR19 inspection
The price is fixed before any work begins. It’s based on:
- Site requirements such as sign-in and permits
- The size of the system
- Access, including roofs, risers and ceiling voids
- Whether several sites go on one quote
Kitchens, offices, schools and hospitals are all priced the same way: how much there is, how we reach it, what state it’s in and when we can work. Call for a fixed quote and we’ll explain each part.
What to send for a quote
There’s no need for technical detail. Just send:
- Where the site is and what kind of site it is
- The paperwork from the last visit, if you have it
- The roof, plant room or outside wall the system runs to
- Detail shots of panels, filters and grilles
Quoting starts with a diagnosis, from your pictures and details or, where that isn’t enough, a survey on site. After that, you get a fixed price for the work so you know the cost before work begins.
What we do, step by step
A visit follows the same order every time: sheeting and protection first, isolate whatever needs isolating, carry out the TR19 inspection, clear away and leave you the report. The visit itself takes a couple of hours for a typical kitchen extract system. Expect the work in Twickenham to happen after your last customer leaves, not during trading.
- Post-clean verification is booked once the clean is done.
- The same access points are opened up.
- Grease readings are taken again at set points.
- Photos are taken to show the condition after the clean.
- The results are reported, with anything missed flagged.
Before we arrive
- Allow time for equipment near the work to be turned off and cool down
- Let us know how we reach the system, including roofs, risers and plant rooms
- Arrange a key holder or contact on site

To get a fixed quote, call us on 0345 646 2711, or email photos with the site type, your trading hours and a short description of the system. Photos and the last report, if you have one, make the quote quicker. We typically come back within one working day.
Advice
Common problems we fix in Twickenham
Grease is fuel. A flare-up on the range can be drawn into the canopy and duct, and from there a fire can spread through the ductwork. Knowing how much there is lets you act before it becomes a hazard.
It’s time to book a visit if you see:
- Kitchen extract systems with no recent grease readings
- Insurance renewals needing proof of TR19 cleaning
- Sections of duct that can’t be reached
- Ductwork where grease may be over the TR19 limits
If you run catering at a historic house or estate in the area (Richmond House is about 0.5 miles east), event kitchens in older buildings often have awkward duct runs that need planning.
Before booking anyone
- Whether the work can be done while the site is closed
- Whether VAT is included
- If they look at the system before pricing
- If the quote is a fixed price or an estimate
Staff cleaning versus specialist work
Staff cleaning doesn’t replace a specialist visit; it supports it. Clean filters and tidy surfaces slow the build-up, but hidden parts of the system still need specialist attention.
If your staff spot something between visits, like drips, unusual noise, smells or damaged filters, it’s best reported rather than tackled in-house. We can diagnose it and quote.
FAQs for Twickenham
Can parking be tricky for a job in Twickenham?
London parking can be tight, so details of loading bays and permits help. Where restrictions apply in the day, an evening or overnight visit usually gets round them.
Which fire service covers Twickenham?
It’s London Fire Brigade, which covers Twickenham. It’s worth keeping your fire risk assessment, TR19® certificates and photo reports together, ready to show.
How long does a TR19 inspection take?
Expect it to take a morning or less for one kitchen, more where there are several systems. The visit is timed so cooking is not disrupted.
At what point does grease need cleaning?
Between cleans, the mean should stay at 200 microns or below, and anywhere at 500 microns or more needs spot cleaning straight away.
What’s TR19?
It’s BESA’s specification and the benchmark insurers, fire officers and EHOs look to. 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, TR19® isn’t legislation. The Fire Safety Order 2005 still requires the responsible person to manage fire risk, and grease in the extract is part of that. Many insurance policies also require TR19 adherence.
What is grease thickness testing?
The Wet Film Thickness Test (WFTT) and Deposit Thickness Test (DTT) measure how thick the grease is at a given point. Readings are taken at set points through the system.
What does TR19 inspection cost?
We don’t publish prices, because the cost 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 we start.
