TR19 inspection in Tisman's Common, done properly
BESA sets minimum cleaning intervals by daily use: heavy use (12 to 16 hours a day) every 3 months, moderate use (6 to 12 hours) every 6 months and light use (2 to 6 hours) every 12 months. Grease testing shows whether your kitchen needs cleaning more often than that. We’re often asked to deal with sites with gaps in their extract records and ductwork where grease may be over the TR19 limits, on wet film thickness tests, deposit thickness tests and access surveys.
In a small place like Tisman's Common, kitchens are often in older or extended buildings, with long single-storey duct runs, and those horizontal sections are where grease settles. Access, parking and timings are agreed before the day.
Think of the report as the system’s health record: a dated account with photos of everything we did. Grease extract cleans are also certificated to TR19® Grease through the BESCA VHE portal and sits alongside the report.

What TR19 inspection looks like in Tisman's Common
Tisman's Common sits within the area of West Sussex Fire and Rescue Service. The Fire Safety Order puts the duty on whoever runs a kitchen to control its fire risk, and a greasy duct is fuel. We cover Tisman's Common, about 33 miles from central London, as part of our work across London and the South East. Evening, overnight and weekend visits are all possible.
School kitchens, at schools like Pennthorpe School for example, are usually cleaned in the holidays so no lunches are lost. Volunteers running a hall kitchen near St John the Baptist, or anywhere in Tisman's Common, may not know when the extract was last cleaned, and a grease test settles it.

Why deal with it now?
Catching heavy deposits early keeps the fix small. Left alone, grease keeps building between cleans. If the system at a site near Tisman's Common fails, there may be nowhere nearby to move to.
The price reflects the work, not guesswork. That is why we survey first, from pictures or on site, and why the quote is fixed before work begins.

The process
Your trading hours come first. 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 job takes around an hour or two per canopy and duct system. For a village or hamlet like Tisman's Common, tell us about narrow lanes, gates and parking when you book.
- After the clean, we arrange a time to check the system.
- We open the access points used on the clean.
- We repeat the WFTT or DTT readings.
- Photos are taken to show the condition after the clean.
- The results are reported, with anything missed flagged.
How to prepare
- Let us know about permits to work or site inductions
- Tell us the best time to work, such as after service or at a weekend
- Let us know how we reach the system, including roofs, risers and plant rooms

What affects the cost of TR19 inspection
The quote reflects the site in front of us. We take into account:
- When the work can happen, such as evenings, overnight or weekends
- Parking and loading at the site
- Whether we need access equipment or extra panels
- The condition of the system
Every site is different, so we price each one individually. Size, access, the condition of the system and when we can work all play a part.
What to send for a quote
What to send for a quote:
- Any previous report or certificate
- When the site is open and when it’s quiet
- The roof, plant room or outside wall the system runs to
- The postcode and the type of business
To help us quote: the address, the type of site and when it’s open, photos of the system and any previous report or certificate. Then ring 0345 646 2711, or email photos.
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 can quote for the whole system.
The Fire Safety Order 2005 puts the duty to manage fire risk on the responsible person, which may be the employer, owner, landlord, FM or managing agent. Where responsibility is shared, records matter even more.
Looking after it afterwards
After the visit, a few habits help the work last:
- Keep access panels clear and unpainted
- Keep to the recommended interval
- Send TR19 audit reports to your insurer on request
- Mention new equipment or longer hours at the next test
After post-clean verification, file the results with the cleaning certificate. Together they show the system was cleaned and checked.
Keep certificates, reports and readings in one place so you can produce them quickly.
