If I changed my rear cassette from a 12-25 to a 11-28, would the chain length , rear derailleur need changing, it' would still be an eleven speed cassette

    yes, chain should be a bit longer (so that things don't end badly if you shift to big-big)

    rear mech b screw adjustment to set correct spacing
    my bike - faster than god's and twice as shiny

    ...although it could be that your chain is just a bit too long at the moment! I would suggest checking it but, if it does need to be longer, then be very careful about how you achieve that given that certain pins/links are not designed to be reused.

    I changed the cassette over at the weekend, no problems whatsoever.
