The digital toolbox that covers you on site.

Records, deadlines and paperwork in one place, with an assistant on WhatsApp at any time.

What Mustr covers

Incidents and near misses
Reported on WhatsApp or in the dashboard. Each report is checked against RIDDOR 2013, given its reporting deadline if it looks reportable, and the F2508 is drafted for you to check.
COSHH and work at height
Points to check are flagged on every incident report.
Sites and CDM 2015
A record for each site, with the F10 notification details ready for you to check.
Toolbox talks
Log talks and attendance from WhatsApp or the dashboard, with a photo of the sign-in sheet.
RAMS and policies
Send documents to your crew on WhatsApp and see who has acknowledged the current version.
Plant and equipment
A register of plant, tools and lifting gear, added from WhatsApp or the dashboard.
Compliance records
Company records, cards and training, the PPE issue log, noise and vibration exposure and health surveillance.
Accreditation reminders
Keep your CHAS or SSIP renewal date on file and get a reminder before it lapses.
Evidence pack
Export the records you have logged as one pack for your accreditation or a client. On the Crew and Enterprise plans.

Step 1
Message
Someone on site messages the Mustr assistant on WhatsApp and says what happened, in plain English.
Step 2
Record
Mustr records it in your dashboard. If a detail is missing, the assistant asks on WhatsApp.
Step 3
Approve
You check every draft. A document leaves your business only after a person approves it.

One flat price per company, not per user or per site. Cancel any time. Crew limits are fair use and never stop anyone reporting an incident.

When is the assistant available?: The assistant is on WhatsApp at any time. Your team messages it like any other contact. There is no app to install.
Does Mustr give health and safety advice?: No. Mustr records what happens on site, tracks deadlines and drafts paperwork for you to check. It does not replace your competent person or your own judgement.
How does Mustr decide if something is reportable?: Mustr uses AI to read each report against RIDDOR 2013 and records whether it looks reportable and by when. You check every draft before anything goes to the HSE.
Does Mustr submit to HSE for me?: No. Mustr drafts the report and shows when it is due. You check it and submit it to the HSE yourself.
Is my data safe?: Each company sees only its own records. The database enforces this for every account, and we never share your records with other customers. The services we use to run Mustr are listed in our privacy policy.
What happens if my subscription ends?: The dashboard asks you to pick a plan. Mustr keeps accepting incident reports on WhatsApp, so no safety record is lost.
