If you are excused from serving

 

If you are not qualified to serve, or if the Coroner agrees to your reason for asking to be excused, we will write to you to say that you do not need to come to court.

You do not need to do anything else.  We will not ask you to serve again in future.  It is possible you may get a summons from the criminal court in the future as they have a separate jury system to ours.  You would need to explain your situation to them and ask to be excused.
