I'm having problems with the lights in my building. I've tried changing the bulbs but the switch at the mains keeps tripping. Is there anything I can do as a layperson or is this matter for an electrician?

With an RCBO it is often difficult to tell without testing if it is tripped by an Earth Leakage fault or an overload.
They will also trip if incorrectly fitted and not properly tested by an incompetent installer.
