The same thing happened to me this month. I received a payment equal to the previous months payment on the 29th, and then another slightly increased payment on the 30th. (I am guessing that the increase is the annual pension increase). Like you, I only started receiving my pension from Capita in January having left service back in 2002.
I did phone Capita up and managed to speak to someone. The man on the phone stated that they had received a few calls about this with others having the same issue, and that the extra payment was planned and agreed and nothing to worry about and that we should still receive our normal monthly pension payment at the end of May.
