TR19 inspection in Dollis Hill, done properly
Insurance policies often require evidence of TR19® cleaning and inspection. Without it, a claim can be refused or reduced. Our TR19 audits give sites in Dollis Hill and across Greater London a clear record of the system’s condition. If you are dealing with missing TR19 certificates or history and post-clean verification after another contractor’s clean, we can help, from insurer audits, post-clean checks and access surveys onwards.
London kitchens are often tucked into basements or the back of a building, and the duct may run up through several floors before it discharges at the roof. In Dollis Hill, as elsewhere in the capital, a long duct run means more access points to open and more grease to remove.
A written report with pictures follows every visit, so there’s a dated record of the work. Kitchen extract cleaning to TR19® Grease is certificated through the BESCA Vent Hygiene Elite portal.

What we do, step by step
Protection comes first: floors, worktops and anything near the work are covered. After that, the system is made safe and the work begins. It takes an hour or two for a single kitchen, longer for a large or complex system, and we clear up before we go. Security desks and permits-to-work are routine in London, so let us know what your building in Dollis Hill needs from us.
- The visit is arranged for when the kitchen isn’t busy.
- We look over the canopy, plenum, ducts, fan and discharge.
- Grease readings are taken at set points using WFTT or DTT.
- Photos are taken at each point, and access gaps noted.
- You get a report with readings, pictures and recommendations.
How to prepare
- Clear loose items from the work area
- Agree a time when the area can be out of use
- Tell us where we can park and unload
Ask for a quote
For a fixed quote, call 0345 646 2711, or send details by email with the site type, your trading hours and a short description of the system. A few pictures and your last certificate or report help a lot. We normally come back within one working day.
Advice
When to call us in Dollis Hill
Grease in a duct is flammable 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. Measuring it is the first step to keeping it under control.
Most sites get in touch when they notice something like this:
- Surveys needed before quoting a full clean
- Kitchens whose menu or hours have changed
- Kitchens taken over with no cleaning records
- Extracts that have never been grease tested
School kitchens, at schools like Our Lady of Grace Catholic Junior School for example, are typically cleaned in the holidays so no lunches are lost.
What your quote should include
- Whether a survey comes first
- What’s included in the scope, part by part
- Proof of insurance
- What paperwork you get at the end

What affects the cost of TR19 inspection
Your quote is based on your site. We consider:
- The times the site is available
- Travel, parking and unloading
- How easy every part is to reach
- What state the system is in
Putting the work off seldom saves money. Problems in a system tend to grow, and a neglected system can mean more work. If you’re not sure what’s needed, ring 0345 646 2711 or use the quote form and we’ll give you an honest view and a fixed quote.
What to send for a quote
To speed up the quote, send us:
- The postcode and the type of business
- A few general shots of the system
- Anything you’ve noticed, such as smells, noise, drips or poor airflow
- How we’d reach plant on a roof or in a plant room
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 we start.
Different parts, different methods
Canopy and plenum
Filters can look fine while the plenum behind them is heavily coated. So we measure behind the filters, not just in front.
Vertical risers
Risers in multi-storey buildings can pass through other areas, so access is planned in advance.
TR19 inspection in Dollis Hill: the local picture
The FSA’s food hygiene register includes about 26 pubs and bars and about 6 hotels, B&Bs and guest houses in and around Dollis Hill, up to about a mile and a half out. Where they serve hot food, their kitchen extracts need cleaning to TR19® like any restaurant’s. Fire safety in Dollis Hill falls to London Fire Brigade. Fire and rescue authorities enforce the Fire Safety Order in most non-domestic premises, and in a kitchen that fire risk includes the grease in the extract. Kitchens in Dollis Hill get their food hygiene inspections from Brent council. Extraction counts as kitchen equipment, so its condition can come up on the day. A dated certificate in the maintenance file answers the question before it’s asked.
Commuter trade near Brent Cross West station can mean long cooking hours, and long hours put a kitchen into BESA’s more frequent cleaning bands. Where a hall near Church of St Michael, or anywhere in Dollis Hill, hosts lunch clubs or events, its extract gathers grease just as a café’s does.

Why it’s worth doing now in Dollis Hill
Finding a hotspot early means a targeted spot clean rather than a bigger problem later. Ignored, the layer only gets thicker. A busy site in Dollis Hill builds up dirt and wear quickly, so putting it off makes the eventual job larger.
When the work has to happen, how we reach it and how big the site is all affect the cost. We take each of them into account, and the price is fixed before any work starts.

Common questions in Dollis Hill
What do you need to know about parking in Dollis Hill?
Tell us where a van can stop near your site in Dollis Hill, and about any building rules on loading. If the building has a loading slot system, we will book into it.
Which fire authority looks after Dollis Hill?
Dollis Hill is in the area of London Fire Brigade. A recent cleaning certificate and a note of the next clean date show that grease in the extract is being managed.
Do you work in Dollis Hill?
Yes. We work across Greater London, Surrey, Kent, Sussex, Hampshire, the Isle of Wight, Berkshire, Buckinghamshire, Oxfordshire, Hertfordshire and Essex, and that includes Dollis Hill.
How much notice do you need?
It depends on the time you need and how big the job is. Mention your preferred dates with your enquiry, and for anything urgent, ring our 24/7 emergency line.
How often should grease be tested?
That varies with the kitchen’s daily use. BESA’s minimum cleaning intervals are every 3, 6 or 12 months for heavy, moderate and light use, and testing shows if your kitchen needs more.
Is TR19 cleaning the law?
No, TR19® isn’t legislation. But the responsible person must assess and reduce fire risk under the Fire Safety Order 2005, 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.
Why survey before a clean?
We look at the system from canopy to discharge, take grease readings and check access. From it, we plan the clean and quote a fixed price.
