Yes it does say Wylex. And there does appear to be 2 blue ones not used. Although there are three red ones for "sockets" which I will have to check what they are for.
i would pull the ones you think are spare out (those are old style wylex plug in breakers) and check they don't effect anything you care about (immersion heaters or individual sockets perhaps)
the ratings of the breakers that are in the spare ways is not a problem as you can still get breakers for wylex standard boards (the current ones look different but they still fit the same boards)
