The “new” Reg 63(1)(b) for pensioners and its CTB sidekick are yesterday’s news. You can’t take your eye off the ball for a nanosecond with this stuff.
The latest position (at least it was when I last looked) is in this very recent thread:

I’m just pondering the consequences of the bug that Julian has found. Should be OK for LP earnings disregard, because that applies to earnings irrespective of the number of hours worked (unless you want to argue that you cannot have “remuneration” from work that isn’t “remunerative”, in which case it isn’t earnings – that would be fun). But child care disregard would be a problem I think. You do have some sympathy for the people trying to tie down all the consequential amendments when you discover things like this.
