TR19 inspection in Witley, done properly
TR19® Grease says grease should not exceed a mean of 200 microns between cleans, while a reading of 500 microns or more anywhere calls for immediate spot cleaning. Grease testing shows which side of those lines you are on. The work covers post-clean checks, deposit thickness tests and pre-clean surveys, and people most often call us about extracts that may be over the 200 micron mean and an insurer’s request for a TR19 audit.
For a kitchen in or near Witley, the visit is planned around opening hours and the journey, and the clean covers the whole system, as it would anywhere: canopy, filters, duct, fan and discharge, with a certificate and photo report at the end.
Accreditations are easy to claim and worth checking. Ours are BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease, plus CHAS, SafeContractor and ISO 9001, with full insurance on top.

Between visits
Once we’ve finished, these simple steps help:
- Mention new equipment or longer hours at the next test
- Share inspection reports with your insurer or broker when asked
- Flag oily drips near the extract
- Keep canopy edges and gutters wiped down
Each report suggests the next clean and the next test, from the measured grease and the kitchen’s hours.
When cooking hours or the menu change, check the interval still fits. A quick grease test answers the question.
Witley questions
Which fire service covers Witley?
Witley is in the area of Surrey Fire and Rescue Service. It’s worth keeping your fire risk assessment, TR19® certificates and photo reports together, ready to show.
Can the work in Witley be done at night or at weekends?
Yes, we can come after you close and finish before you open. It means the site in Witley keeps running as normal. Tell us your opening hours when you ask for a quote.
Can you inspect our extract for our insurance company?
Yes. Our TR19 audits cover readings, photos, access and a recommended cleaning interval. It’s set out for your insurer or broker.
What if parts of the system can’t be reached?
We never leave them off the paperwork. The report says which parts couldn’t be reached and why, and we can quote to improve the access.
Is Witley in your area?
Yes. We cover Witley and the rest of Surrey, within our South East and London area. To book, call 0345 646 2711, or send details by email.
Is TR19 cleaning the law?
No. It’s the benchmark rather than the law. In practice, an insurer can refuse or reduce a claim without proof of TR19 cleaning, so it matters in practice.
Which accreditations do you hold?
CHAS, SafeContractor, ISO 9001 and BESCA Vent Hygiene Elite membership, cleaning to BESA TR19® Grease. We have been trading since 2009 and we’re fully insured.
How far ahead should we book?
Book as early as you can for planned work, especially if the next clean or test is due soon. For emergencies, we take calls 24/7.
What we’re called out for in Witley
Grease builds up as cooking vapour cools inside the extract. The thickest layers can sit out of sight in the plenum, at bends and along flat runs.
Any of these means the system needs a check-up:
- Extracts that have never been grease tested
- Missing TR19 certificates or history
- Systems that need surveying before cleaning
- Missing access panels found on survey
Bursars and site managers at schools such as The Chandler CofE Aided Junior School tend to book extract cleaning for when the kitchen is empty.
What your quote should include
- Whether the quote shows VAT
- Their accreditations, such as BESCA Vent Hygiene Elite, CHAS or SafeContractor
- Whether the figure could change on the day
- What happens if part of the system can’t be accessed

Fixed quotes for TR19 inspection in Witley
Before we fix a price, we need to know a few things. We look at:
- The condition of the system
- Whether we need access equipment or extra panels
- Site requirements such as sign-in and permits
- The number of sites or systems
Kitchens, offices, schools and hospitals are all priced the same way: the size of the job, access, condition and working hours. Ask for a fixed quote and we’ll explain each part.
What we need to know
When you call or email, 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
- How we’d reach plant on a roof or in a plant room
- Any previous report or certificate
Need a price for TR19 inspection? Please ring 0345 646 2711 or send us an email with a few details about the site. We will explain what we’d do and send a fixed quote before anything is booked.
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. A recent inspection report means you’re ready when asked. Rural sites can’t always move to another kitchen or room when something fails.
The cost depends on how big the system is, the condition it’s in and how easy it is to reach. You get a fixed price before work begins, so you know where you stand.

- In business since 2009

What the work involves, part by part
Vertical risers
In buildings with several floors, the riser may pass through other tenants’ space, so we arrange access ahead of time.
Horizontal duct runs
Grease can gather thickly at bends and along long runs, well away from where anyone looks.
Grease, kitchens and Witley
The FSA’s data shows about 3 bars, pubs and nightclubs registered across Witley and its immediate surroundings (about a mile and a half). Breakfasts, bar meals and functions all put grease into the extract wherever they’re cooked. It’s Waverley council that sends environmental health officers to food businesses in Witley. An officer looking round a kitchen will see the canopy, and grease there is hard to miss. Our report lists what was cleaned and when, which is useful to have ready. The fire and rescue service for Witley 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.
Commuter trade near Milford (Surrey) station can mean long cooking hours, and long hours put a kitchen into BESA’s more frequent cleaning bands. A hall kitchen that only cooks for events, whether near Church of All Saints or elsewhere in Witley, still needs its extract cleaned, just less often.

How it works
We work around your opening hours, not the other way round. Most visits are booked for when the area is out of use, such as evenings, overnight, early mornings or weekends. When the team arrives, the work area is protected and the relevant equipment is switched off to cool, and the work takes a couple of hours for a typical kitchen extract system. Somewhere like Witley, lanes, gates and parking are worth mentioning in advance.
- First we book a time that will not disrupt cooking.
- We look over the canopy, plenum, ducts, fan and discharge.
- We take WFTT or DTT readings at set points along the system.
- We photograph the test points and record any sections we can’t reach.
- The findings go into a report with readings, pictures and a recommended next clean.
Getting ready for the visit
- Let us know about permits to work or site inductions
- Name a contact who can let us in at the agreed time
- Allow time for equipment near the work to be turned off and cool down
