PETIS (Public Emergency Telephone Information System) describes a dedicated telephone line used to provide recorded or live public information during a major incident, so as to divert non-emergency enquiries away from 999/112 and official switchboards. In legal practice it is encountered in emergency planning, business continuity, procurement and telecoms contracts, and in civil contingencies compliance.
PETIS is not a term defined in legislation or case law. In England and Wales, Scotland and Northern Ireland it is commonly referenced as a tool used by Category 1 responders and other public bodies to help discharge the Civil Contingencies Act 2004 duty to warn and inform the public. In Ireland, comparable “public information lines” or “emergency helplines” are established under national emergency management arrangements. Usage and purpose are broadly consistent across the UK and Ireland, though naming and technical delivery may vary.
Typical features include high-capacity call handling, recorded messages (IVR), resilience and failover, and, where staffed, call scripts and escalation. Legal considerations include data protection where calls are recorded or logged, accessibility, accurate and coordinated messaging, public law duties, and procurement/outsourcing controls and SLAs with telecoms providers. Sometimes also described as a public emergency helpline or public information line.
