if your cautioned before your 17th Birthday its GONE when you turn 18
All other cautions may be there for life etc but they are all taken care off by the SPENT CONVICTIONS program
Which basically says after a certain amount of time from the conviction you dont have to tell ANYONE about them this was part of the rehabilitaion of offenders act of 1974 i think
The old bill will ALWAYS have the record of it though
IF you need help with the time a conviction becomes "spent" see the link below
