Construction compliance for UK contractors

Report it
from site,
on WhatsApp.

Starting with RIDDOR: site managers text what happened. Mustr checks it against RIDDOR 2013, tracks the HSE deadline and drafts the F2508 for you to send.

How it works

From a message on site to a form ready for HSE.

  1. 1

    Text what happened

    Your site manager sends a WhatsApp message describing the incident, in plain English, from site.

  2. 2

    Mustr checks it against RIDDOR

    Mustr checks the report against RIDDOR 2013 and records whether it looks reportable, how severe it is and the reporting deadline. You can check every classification in the dashboard.

  3. 3

    Check the F2508 and send it

    For reportable incidents, Mustr drafts the F2508 from the details in the message for you to review and submit to HSE.

Built around how sites work

Deadlines tracked from the start
The reporting deadline is recorded as soon as an incident is logged. Specified injuries: 10 days. Over-7-day absences: 15 days. Fatalities: immediately.
No portals, no paper forms
No RIDDOR online portal, no paper forms, no chasing site managers for details. It starts with one WhatsApp message.
A record of every incident
Each incident is kept with its date and time, the original message, the AI confidence score and whether a person has checked it.

Failing to report under RIDDOR is a criminal offence

Most missed reports aren't deliberate. Sites are busy and paperwork gets missed. Mustr records the reporting deadline as soon as an incident is logged, so it's in front of you before it's due.
