I think I am going to state FL150 as my answer. Hit LAM at that level then go around the hold a couple of times dropping to ALT 7000' (unusual in the London TMA), based on an estimated QNH, then start the procesdure (again, something odd in the London TMA). I am not sure how correct this is though!!

The TOD on your flight plan, is that shown within the pages of the "plog"? Is the actual flight plan as filed with ATC also given to you?
