The FCA’s Handbook Notice 133, published in October 2025, confirmed rule changes effective from 1 January 2026 that raise the threshold triggering referral to specialist medical condition directories from £100 to £200, and introduce a one-entry-per-firm rule for directory listings to eliminate so-called brand stacking, where firms appeared under multiple names in ways the regulator judged offered limited consumer benefit. The changes apply across insurers, Lloyd’s managing agents, intermediaries and appointed representatives writing UK retail travel business.
