If you go the Account icon in the Britbox channel/app (the little head/user icon to far right) and then scroll all the way to the bottom, are you able to "Sign Out"?
Also, are you sure you are using the Britbox channel app https://channelstore.roku.com/details/ae9a77e6a02e540039dccfcd6fc53706/britbox and not the "Britbox on the Roku Channel" channel/app?
