If you have SKY, then simply choose it from the list of different BBCs. I am guessing Freeview works in the same way.
"BBC One Scotland can be seen on all television platforms in Scotland, on channel 1, or 101, depending on the system, and in other areas of the UK via satellite, cable and on some other digital television platforms. Programmes shown exclusively on BBC One Scotland can also be watched again across the UK for 7 days after transmission on the BBC iPlayer service"
