EGLL SIDs
All SIDs out of EGLL have an altitude restriction of 6000 ft with conditional altitudes set as well (e.g.. CPT 8 dme 4000 ft or above - don't think that is factually correct but you get the idea).
As previously stated, oct cleared to a flight level then you set Standard.
CPT departures from 09R generally have an amendment given by the tower controller along the lines of "at LON 2 due turn right heading 220deg and climb to altitude 4000ft
