Surrey · TR19 inspections and grease testing
Dora's Green TR19 inspection
TR19 inspection for Dora's Green, from a team that has been trading since 2009. Evenings, overnight and weekends, plus a 24/7 emergency line.
- Insurers asking for TR19 evidence
- Ductwork where grease may be over the TR19 limits
- Parts of the system left out of past cleans
Keeping the system healthy
Aftercare is simple, and it makes the next visit easier:
- Wipe the canopy surfaces regularly
- Clean or swap grease filters as often as the kitchen needs
- Share inspection reports with your insurer or broker when asked
- Look out for grease drips round the canopy edge
Readings of 500 microns or more are highlighted as needing immediate spot cleaning, and we can quote to do it.
Keep filters clean and in place. Gaps around filters let grease get past them.
How we handle TR19 inspection in Dora's Green
A grease test measures how thick the grease is inside a kitchen extract system. Readings are taken at set points using the Wet Film Thickness Test (WFTT) or the Deposit Thickness Test (DTT). From the numbers, you can see whether cleaning is due. If you are dealing with pre-clean surveys before a first TR19 clean and heavy grease suspected in the plenum or ducts, we can help, from post-clean checks, access surveys and insurer audits onwards.
For a kitchen in or near Dora's Green, the visit is planned around opening hours and the journey, and the clean itself is the same full TR19® job as in any town: canopy, filters, duct, fan and discharge, with a certificate and photo report at the end.
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’re fully insured.

Why act early in Dora's Green
Skipping grease testing leaves the cleaning interval to guesswork. If grease reaches 500 microns anywhere, TR19® Grease calls for immediate spot cleaning, and you can only act on that if you’ve measured it. Systems in rural buildings are often out of sight and out of mind.
No two sites are the same, so we price each one individually. The size of the job, how we reach it, its condition and the working hours all play a part.

How we price TR19 inspection
We do not publish a price list, because sites vary so much. What we look at:
- Whether several sites go on one quote
- How easy every part is to reach
- A single visit or a regular plan
- The condition we find in the survey
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 any work starts, so you know where you stand.
Asking for a quote
When you contact us, it’s useful to have:
- Where the site is and what kind of site it is
- When the site is open and when it’s quiet
- The roof, plant room or outside wall the system runs to
- Wide photos of the system and the area around it
Every quote begins with a look at the system, either from photos and details you send or from a site visit. Then we send a fixed price, before work begins.
What your team can do, and what needs us
A few tasks are always specialist work: entering ducts, working on fans, testing dampers and taking grease readings call for the right kit, training and safe access. That is our job.
Staff cleaning does not replace a specialist visit; it supports it. Regular in-house cleaning slows the build-up, but the parts you cannot see still need a specialist at the right interval.
What happens on the day
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 anything from an hour for a small canopy and short duct to a good part of a day for a large site, and the area is cleaned down before we leave. If the van will struggle with a lane or gateway near Dora's Green, let us know and we’ll plan around it.
- First we look at the system’s cleaning history, if there is one.
- The layout is traced from the canopy to the discharge.
- We note where access panels are and where more are needed.
- Grease readings are taken and pictures recorded.
- You get a report and a fixed quote for the clean.
How to prepare
- Have your last certificate or report to hand
- Clear the space around the work
- Make sure someone can let us in and lock up afterwards
Ask for a quote
We don’t publish a 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 get going, ring 0345 646 2711 or email us.

What TR19 inspection looks like in Dora's Green

A pub or hotel kitchen that cooks every day builds up grease in its extract like any other. The fire and rescue service for Dora's Green is Surrey Fire and Rescue Service. In most workplaces, including commercial kitchens, it’s the fire and rescue authority that enforces the Fire Safety Order.

If your kitchen is in a listed or historic building, like the houses around Dora's Green (Farnham Castle is about 1.7 miles south-east), fitting access panels needs care.
