Count,
As I'm prone to getting my "maffs" wrong I've done a quick double check.
From AFPRB 07
WO1 Level 7 = £118.01 per day (£43077)
Enhanced Rate = £41.12 per day (£15008)
Total £58,085
PES(A) Level 22 = £58,674
Bear in mind that you can't take a pay drop (level 21 = £57,584).
Maybe the pay rise wasn't so bad after all!
Sorry if I appear to be pedantic, I'm not trying to be, just helping to make a point.
