Thanks chaps,
Yes I agree that FPS are the peeps to rely on although it is good to hear your views too.
I am in a slightly different boat as I joined at approx age 24 and am now 44 so I believe from previous discussions on the topic that my cost to purchase added years may be prohibitively expensive however, I suppose I can just purchase what I can afford?
As it stands, if I leave at 55, I will have 31 years service and so I look forward to seeing how much the extra 8 or 9 years will cost me to add in?
When I hear from the FPS I'll post any details that may be of use to others.
Regards
