TR19® Compliance, FAQ & Trust

TR19® Grease Compliance & Reporting

TR19® GREASE is the recognised industry guidance for the cleaning and maintenance of commercial kitchen extraction systems. Many insurers and enforcement bodies expect cleaning to follow these principles.


Proper compliance is not just about cleaning — it’s about evidence. After each extraction clean, Ventra Services provides:


  • Pre - and post-clean photographs
  • Notes on system condition
  • A clear compliance report
  • Certificate of hygiene for your records


This documentation supports insurance, audits, and fire risk assessments.
