Do you have an overhead TT supply?
As you seem to be a malteser, you'd be better off asking in the
Electrics Outside of UK
section of DIYNOT.COM.

The laws of nature and physics are the same there as here, surely?
Does your supply come in overhead, or underground?
I believe that overhead TT supplies are particularly susceptible to nearby lightning strikes.
Do you have a lot of computer equipment which could be pushing the background leakage high, so not needing much to push it over the edge?
What is the rating or the RCD? Is it actually an RCD or a voltage operated ELCB?
If you have neighbours do they have the same problems?
Have you spoken to the local engineering people in your supplier for advice?

No, from underground
An RCD. The RCD rating is 40A 30mA at the upper consumer unit and 40A 100mA at the common area of the flat.
and however the neighbours don't have the same problem.
Could it be the induced magnetic field came from lightning to cables which detects the RCD?
