This subject has confused me too! I got a letter from DWP asking if I wished to top-up my contributions; I currently have 41 years full contributions. Then the letter went on to tell me that the qualifying number of years is now 30.... so why would I want to buy more??? How about a refund?
And while I'm getting steamed up about it, why does the governemnt reduce the number of qualifying years when it clearly can't afford to pay the pensions in the first place? surely they should be increasing the qualifying period if anything, along with raising the pension age?
It's difficult to say what my wife does...
