I'm trying to work out the pension thing, and I'll be the first to admit I'm not 100% about this, so let me know if I've made a mistake:
In 2011/12 the standard allowance for under 65s was £7,475.
For over 65s it was £9,940 (an extra £2,465).
In 2012/13 the standard rate will be going up to £8,105 and over 65s will be frozen at £9,940 (not increasing to £10,570 as it would have done).
In 2013/14 the standard rate will increase to £9,205 and the over 65s rate will stop, brining them in line with the £9,205 rate. (not increasing to £11,670 as it would have done).
By those figures, even in 2014 they would have less allowance than they do now (excluding the additional £2,465 they would have had).
How are they better off?
*EDIT* I missed it before but there IS an increase in 2012/13 from £9,940 to £10,500 so they will technically be be better off by £560 but would have had this anyway if the rules hadn't changed... Then it's unclear whether this £10,500 is fixed for 2013/14 and beyond.
Either way, it's going to make as little-as-makes-no-odds in 2012/13 and then start to have an impact in 2013/14.
I think the point Glaucus was trying to make was that there was no guarantee that the over 65 rate would have continued to track at ~33% above the standard rate but then there's equally nothing to suggest that it wouldn't have.
