FCA Finalizes Single‑Portal Cyber and Third‑Party Incident Reporting, Effective March 2027

The change delivers clearer thresholds and short forms for firms, giving supervisors comparable data to track supply‑chain weaknesses.

Overview

  • Firms will submit incident and third‑party outage reports through one portal shared by the FCA, Bank of England and PRA, replacing fragmented channels.
  • Final guidance sets clearer thresholds, definitions and examples, with most directly supervised firms able to file short‑form reports.
  • The regime takes effect on 18 March 2027, giving firms roughly 12 months to prepare processes and tooling.
  • Regulators will analyze the new data to spot trends, assess potential critical third parties and share sector‑wide resilience insights.
  • The FCA cites rising supplier exposure, noting over 40% of 2025 cyber incidents involved third parties and pointing to recent AWS and Cloudflare outages; duplicative reporting is removed for payment service providers and credit rating agencies.
