TR19 Inspection in Green Cross
TR19 inspections, grease thickness testing, pre-clean surveys and post-clean verification for commercial sites in Green Cross and across Surrey. CHAS, SafeContractor and ISO 9001, and fully insured.
- Confirming a clean reached the whole system
- Extracts that may be over the 200 micron mean
- Uncertainty over how often to clean
Staff cleaning versus specialist work
Your own staff can handle the daily basics: wiping canopies, washing grease filters and recording it in a log. What they can’t safely do is clean inside the ductwork, the fan or the risers, and that’s where we come in.
For ventilation and air handling systems, in-house care is mostly about checks: keeping grilles clear, noting unusual noise or smells and logging filter changes. The inside of ducts and units needs a specialist.
About our TR19 inspection in Green Cross
Insurance policies often require evidence of TR19® cleaning and inspection. Missing records can lead to a claim being reduced or refused. A TR19 audit sets out the system’s condition, with readings and pictures, for sites in Green Cross and the rest of Surrey. If you have kitchens taken over with no cleaning records and systems cleaned on a calendar with no measurements, we can put it right, from pre-clean surveys, insurer audits and wet film thickness tests onwards.
Somewhere as small as Green Cross, commercial kitchens are few: perhaps a pub, a school or care home kitchen, or a hall used for events. Every one of them still needs its extract kept clear of grease.
Duct Doctor has been trading since 2009, and we’re 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.

How it works
We’re used to working while the site is closed. Evenings, nights and weekends are when much of our work happens, so a kitchen or building can carry on as usual the next day. The visit itself takes a couple of hours for a typical kitchen extract system. If the van will struggle with a lane or gateway near Green Cross, let us know and we’ll plan around it.
- First we look at the system’s cleaning history, if there is one.
- We follow the extract from canopy to discharge.
- Access panels are located and any missing ones noted.
- Grease readings are taken and pictures recorded.
- You get a report and a fixed quote for the clean.
How to prepare
- Make sure someone can let us in and lock up afterwards
- Have your last certificate or report to hand
- Agree a time when the area can be out of use

Why deal with it now?
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 Green Cross a current picture. A fault that closes a site in a village like Green Cross affects everyone who depends on it.
Whatever the type of site, the quote works 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 will explain each part.

Honest limits
We’ll always give you a straight diagnosis, so here’s what TR19 inspection won’t do:
- Sections with no access, until panels are fitted
- Heavy deposits found on test, which still need cleaning
- A faulty or failing extract fan
If in doubt, call us on 0345 646 2711 or send us an email and we will say what we think.
What the work covers
- Deposit thickness tests
- Wet film thickness tests
- Insurer audits
- Access surveys
- Pre-clean surveys
- Post-clean checks
Between visits
Results last longer with the right care. Here’s what we suggest:
- Store grease readings where your insurer can see them
- Book the next test on the date in the report
- Have the latest report ready for insurance renewals
- Keep grease filters clean and fitted properly
If any reading is 500 microns or more, the report flags it for immediate spot cleaning, and we can quote to do it.
Test grease regularly instead of relying on the calendar. It shows if build-up is speeding up.
Different parts, different methods
Restaurants, pubs and hotels
A kitchen running from breakfast to late service builds grease quickly. Regular testing shows whether the cleaning interval keeps up.
Vertical risers
Risers can be hard to get into. The survey shows exactly what access there is.
Questions from Green Cross
Which fire and rescue service is responsible for Green Cross?
That’s Surrey Fire and Rescue Service. Records of extract cleaning are a sensible thing to have ready if a fire safety officer carries out an audit.
Which environmental health team covers Green Cross?
The local authority for Green Cross is Waverley council, and its environmental health team does the inspecting. How often a business is inspected depends on the risk rating the council gives it, so it’s worth staying ready all year.
Can you price the work without visiting?
In many cases, yes. Photos of the system and the access, plus your opening hours and last report, are often enough. Where we can’t see enough, we arrange a survey.
Do you carry out TR19 audits for insurers?
Yes. Our TR19 audits cover readings, pictures, access and a recommended cleaning interval. It’s set out for your insurer or broker.
Can the work be done while we are closed?
Yes. Tell us your opening hours when you ask for a quote and we’ll book around them.
How do you keep the site clean during the work?
With sheeting and covers, before anything else happens. The work is kept contained and clean down when we finish.
What happens on a pre-clean survey?
We survey, measure and photograph the system first. The survey can be done from photos and details or on site, as suits the job.
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.
Kitchen extracts in Green Cross
Food Standards Agency data counts about 5 cafés, restaurants and staff canteens in Green Cross and the streets around it, up to about 1.5 miles out. For any of them with a canopy, measuring grease is better than guessing when to clean. The fire and rescue service for Green Cross is Surrey Fire and Rescue Service. Grease in a kitchen extract is a recognised fire risk, and the fire authority enforces the law on managing it in most commercial premises. Food hygiene inspections in Green Cross are the job of Waverley council’s environmental health team. 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.
School kitchens, at schools like St John's CofE Aided Infant School for example, are normally cleaned in the holidays so no lunches are lost. A hall kitchen that only cooks for events, whether near St John the Evangelist or elsewhere in Green Cross, still needs its extract cleaned, just less often. If you run catering at a healthcare site, such as a hospital like Haslemere and District Hospital about 3.8 miles south-east, the extract may need cleaning more often than a part-time kitchen.
