I just made it up.
A fault which is always there (permanent) but sometimes does not show itself.
Sometimes it trips the RCD (high impedance L-E) and other times it trips the MCB (dead short L-N).
Could be explained by a worn flex which moves, although, I think, OP has said all flexes disconnected and still trips or cable underfoot.
In a socket a bit more difficult to engineer - loose parts and slug.

I know - that's why I said I would benefit from a translation!
Fair enough. The L-E fault when it arose would obviously not necessarily have to be 'high impedance' - I suppose it could be something flapping about connected to L which sometimes touched L and other times touched E!

He said he couldn't tell exactly what the fault was. He gave me the option of putting trunking in from other socket in conservatory, going under window sill or disconnecting the socket. I decided just to disconnect it. It has not tripped for almost 36 hours so hopefully sorted. I am quite worried now that he has done something wrong. Please advise?

Ah, that would indicate the fault was in the cable between the sockets - not the socket itself.
So, if correct and it is now disconnected, all should be well.
If this is, or was, a ring circuit he should have reduced the rating of the MCB.
IF that is what has happened.

I would hope this was the only thing which drew attention, because it beeped, and that other boxes were present.
Boxes ?
I wondered, too - but I suspected that it was a reference to "other boxes being ticked" - but maybe I was totally wrong!
I also suspected that there was a "not" missing at the start of the sentence (i.e. " ... not the only thing ...") - but, again, I may be wrong!

All I know is that he had all of the sockets off looking for slugs and using his beeping machine on each one. He took the wires out of the mcb and tested that. He was there for 3 hours and I have had no trips since.
Does that mean that you are not "Still Worried" about this electrician?
Kind Regards, John
Well, he also used a bleeping box and disconnected the wiring at the mcb, initially you gave the impression he had just used a voltage tester. At that point i was worried.
However, i can assure you, i am not worried, as i don't live in your house.

Fair enough - but you didn't live in the OP's house when you said that you were worried, eitherHowever, i can assure you, i am not worried, as i don't live in your house.
