I think they now allowed to use expired BRPs for a few months post 1st Jan.

From HO website: "You may be able to use your expired BRP to travel to the UK until 31 March 2025 if both: your BRP expires on or after 31 December 2024. you still have permission to stay in the UK."

Yes, they’ve said that, but gate agents at airports are the people who get to make decisions about boarding and expired documents will definitely freak them out. The issue isn’t really at border control, where there’s direct access to the databases anyway, it’s at the various stages of delegated border enforcement (boarding a plane, right to rent etc) where this will suck.

You might be able to bully them into accepting them because it’s in Timatic but there will be British residents who are blocked at least temporarily because of this.
