Welcome to the forum I think l'm right in saying that your plant is a variagated Cordyline. It looks as though some of the leaves have possibly been damaged by frost. Usually the dead leaves will come away with a sharp tug downwards, if not you can cut them off with sharp secateurs as close to the trunk as possible. There is a school of thought that says you shouldn't cut them, but l have done so in the past with ones that just wouldn't pull away. It's to be expected that you will lose some leaves over time.
A Cordyline's main problems are coping with Winter wet or an exceptionally cold spell such as "The Beast from the East" a few years back . It looks to be in a fairly sheltered spot. Whereabouts in the UK (l assume !) are you? (Just a general location will do).
