TR19 inspection in Wisley, done properly
BESA’s minimum cleaning frequencies depend on how long the kitchen cooks each day: every 3 months for heavy use of 12 to 16 hours a day, every 6 months for moderate use of 6 to 12 hours, and every 12 months for light use of 2 to 6 hours. Grease testing shows whether your kitchen needs cleaning more often than that. We’re often asked to deal with cleaning intervals that may not suit the kitchen and missing TR19 certificates or history, on wet film thickness tests, post-clean checks and insurer audits.
For a kitchen in or near Wisley, 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.
Each visit ends with a written report and photos, so you have a record of what was done and when. Where the work is a TR19® Grease clean, the certificate is issued through the BESCA Vent Hygiene Elite portal.

Why act early in Wisley
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 Wisley a current picture. Planning a trip to Wisley ahead is easier for everyone than a rushed one.
What you pay reflects the actual work. That’s why we survey first, from pictures or on site, and the price is agreed before we start.

When to call us in Wisley
TR19® is the benchmark that insurers, fire officers and EHOs refer to. TR19® itself is not law, but the Regulatory Reform (Fire Safety) Order 2005 requires the responsible person to assess and reduce fire risk, and grease in the extract is part of that risk.
The symptoms we’re asked about most are:
- Missing TR19 certificates or history
- Surveys needed before quoting a full clean
- Kitchen extract systems with no recent grease readings
- Sections of duct that can’t be reached
For schools such as St Mary's CofE Controlled Primary School, kitchen extract cleaning is typically booked for the holidays, when the canteen is closed.

Wisley kitchens: local notes
There are about 15 cafés, restaurants and staff canteens and about 9 takeaways and sandwich shops in and around Wisley, up to about a mile and a half out, according to the Food Standards Agency’s register. A WFTT or DTT reading tells each of those kitchens whether its grease is staying under the 200-micron mean. It’s Guildford council that sends environmental health officers to food businesses in Wisley. Extraction counts as kitchen equipment, so its condition can come up on the day. Keeping each certificate and photo report on file helps show the extract is looked after. Surrey Fire and Rescue Service covers Wisley. Grease in a kitchen extract is a recognised fire risk, and the fire authority enforces the law on managing it in most commercial premises.
Historic houses near Wisley, such as Byfleet Manor about 0.8 miles north-east, are a reminder that older buildings with event kitchens can have long, awkward duct routes. A hospital like Woking Community Hospital, about 3.5 miles west, is the kind of site where a kitchen may cook for patients, staff and visitors all day.

Landlords, agents and facilities managers
Landlords, managing agents and facilities managers book us, not only the businesses that use the systems. Where a system serves more than one tenant, such as a shared riser, it helps to agree who arranges the work, and we’re happy to quote for all of it.
Managing agents often deal with us directly. Send the address, what’s needed and how access works, and we will send a fixed quote.
Staff cleaning versus specialist work
Good housekeeping makes our visits easier, not unnecessary. Clean filters and tidy surfaces slow the build-up, but hidden parts of the system still need specialist attention.
Keep a record of what your team does. A simple log of filter washes, wipe-downs and checks shows an inspector that the system is looked after between visits, next to our reports.
Questions from Wisley
Do you do school kitchen extract cleaning in Wisley in the summer holidays?
Yes, holiday work suits schools best. With about 4 schools and colleges on the FSA’s register within roughly a mile and a half of Wisley, it pays to plan holiday dates ahead. Tell us your holiday dates and we’ll book the visit for when the site is empty.
Which fire and rescue service is responsible for Wisley?
Fire safety enforcement in Wisley is handled by 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.
What about areas you cannot get to?
We record them on the report, with a note of where it is, and we explain what access is needed, for example new access panels.
How do you protect the area?
We cover floors and nearby surfaces with sheeting before any work starts, and waste is contained as we go. Before we leave, we tidy up and clean down.
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.
Can you inspect our extract for our insurance company?
Yes, for kitchens across the South East and London. Tell us what your insurer has asked for and we’ll set the report out to match.
Do you work in Wisley?
Yes. Our area takes in London and the counties of South East England, and that includes Wisley.
How often should grease be tested?
Enough to be sure grease stays within the TR19® Grease figures between cleans. If readings rise, the interval should shorten.
Honest limits
TR19 inspection can’t fix everything, and we’d rather say so up front. It will not put right:
- Ductwork that was designed or installed badly
- A faulty or failing extract fan
- Heavy deposits found on test, which still need cleaning
If in doubt, ring 0345 646 2711 or send us an email and we will say what we think before you book.
What the work covers
- Insurer audits
- Access surveys
- Post-clean checks
- Deposit thickness tests
- Pre-clean surveys
- Wet film thickness tests
Between visits
So the system stays in good health:
- Store grease readings where your insurer can see them
- Book the next test on the date in the report
- Flag changes in how much frying the kitchen does
- Keep access panels clear and unpainted
Each report suggests the next clean and the next test, from the measured grease and the kitchen’s hours.
Test grease regularly instead of relying on the calendar. It shows if build-up is speeding up.
How the visit works
On the day, we arrive at the time agreed with you, which is often after service, overnight or at a weekend. Anything that needs to be off for the work is switched off and left to cool before work begins, and the area around the work is covered and protected. The work itself takes an hour or two for a single kitchen, longer for a large or complex system. Somewhere like Wisley, lanes, gates and parking are worth mentioning in advance.
- We agree a time when the kitchen is closed or quiet.
- The system is checked from canopy to discharge.
- We take WFTT or DTT readings at set points along the system.
- Each test point and any access problems are photographed.
- You get a report with readings, pictures and recommendations.
Preparing for the visit
- Let us know when the site is closed or quiet
- Make sure someone can let us in and lock up afterwards
- Tell us about access, such as roof hatches, plant rooms, ceilings or locked areas
