Hi Fuji,
I am not aware that infringements automatically require a controller to be stood down (the Controllers at LGW are ANS not NATS - not that it would make any difference).
It may well be the case if a serious or life threatening event occurred but not if there was a simple (and I don't mean to understate the seriousness of infringements) event that required an airliner to be turned early to avoid a light aircraft close to or even inside an airspace boundary that posed a relatively low risk but no actual threat. An infringement could also be a PPL flying at 2510 ft with nobody else near. It's still an infringement, and might set off a radar alarm but it doesn't pose a risk so no stand down and probably no report, just a statistic to be noted.
From what I understand from the CAAs lead on airspace (who is an active PPL himself), the first thing they want is better education and fewer infringements and the last thing they want to be seen as is heavy handed or retributative.
Have a look on
