My Aerad is a little out of date (1999), but a quick glance through the STAR charts gives the following:
Gatwick TIMBA stars: FL160 at BEXIL, FL130 at TANET
Stansted LOREL North stars: FL150 at CLIPY
Luton LOREL South Star: FL130 at HAZEL
Manchester ROSUN star: FL200 at GOLES
etc etc
All of these have a little box which tell you to expect the levels but that actual clearance will be by ATC. Unless they have been removed in recent editions of charts it seems fairly clear to me.
Of course, what are not shown are the various standing agreements between sectors which occur before the star chart begins, such as FL 270 35 before LAM from COA/REFSO for BB/NX arrivals. You should be given plenty of warning about them by the controller anyway.
