AI engineer booking

It books the engineer — you just approve.

When a certificate nears expiry, MillOS finds a local Gas Safe or NICEIC engineer, proposes a slot, and handles all the messaging between you, the tenant and the contractor — automatically.
Integrations

Works where you already work.

MillOS plugs into WhatsApp, Gmail and Google Calendar — so reminders, engineer messages and tenant notices go out on the channels everyone already uses, and every booking lands straight in your calendar. No new inbox to learn.
