Hmmm. You mention main RCD and individual circuit RCDs? Do you mean individual MCB?
A photograph of the board showing the switches and an explanation of what trips would let us understand better . As previously suggested

Did this only start since using this surge lead you mention? Try dissing that for a couple of weeks

For clarification in the extension lead (one of those surge protection extension leads too):
Sky Q box
Xbox/PS4 (only one In use/switched on at one time)
That's it.

Oh dear. Those surge protection extension leads are prone to randomly trip RCDs. They are not really required in the UK and are often "sold" using scare tactics. Suggest you swop it for a normal one and see how it goes.
