Stik - as an ATCO, I'd say it sounds like you got into this situation through trying to do the right thing ie avoiding the gliders. No ATCO could or should blame you for taking that course of action. As a result, you inadvertantly ended up inside CAS, ah well, it happens. What annoys ATCOs, is when it happens and we never find out why either because the a/c troggs through our zone and says nothing or they don't ring back to explain. Honest mistakes are honest mistakes, no two ways about it.
From the start of September, we will be filing on all infringements at Bristol, but only for auditing purposes. The CAA want to know how many infringements occur (with our new airspace) and the reasons, but only so they, and we, can work out a plan of action to try to prevent it from happening again and again, not for any want of "punishing" anyone.
It appears you admitted to yourself you needed help, got it, and did as you were asked by Luton, we as ATCOs couldn't ask for anything else, don't worry about it mate.
