Boring photo, cry for help.

Apologies for the incredibly boring blip. Any electricians out there?? Our RCD keeps tripping. Once a day, most days. Did it this time last year but with a week or so between each trip. Nothing from Feb - Oct. Now it's doing it once a day. Extremely annoying as all the sockets go off. But obviously essential if it is preventing serious damage somewhere.
