    Your crew already use WhatsApp. They message Mustr like they message anyone else.

  • UK law built in

    RIDDOR, the F2508 and the F10 are built in, with reporting deadlines tracked from the first message.

  • CHAS/SSIP evidence pack in one click

    Export the safety evidence your clients ask for, straight from the incidents you have already logged.

How it works

    Mustr classifies

    Mustr checks it against RIDDOR 2013 and records whether it looks reportable and when it is due.

  3. Step 3

    Report ready

    The paperwork is drafted for you to check. You review it and submit.

Questions

Is my data safe?
Each company only ever sees its own data. Incident records are stored in a database with row-level access controls, and we do not share your records with other companies. See the Privacy Policy and Data Processing Agreement linked below for the details.
Does Mustr submit to HSE for me?
No. Mustr drafts the report and tells you when it is due, but you check it and submit it to HSE yourself.
Do I need a card to try it?
No. The 14-day trial needs no card.
