What you can check yourself
Unplug everything on the circuit that keeps tripping and switch the RCD back on. Does it stay on? Plug the appliances back in one by one. The one that makes it trip again is the culprit.
Can you smell burning, or does a socket feel warm? Switch that circuit off and have it checked straight away.
How we fix it
We test every circuit with an insulation resistance tester. That way we find a damaged cable behind the skirting board or a damp outdoor socket without breaking open the wall. Afterwards you get a short report of what was wrong.
