1) Please stop shouting.
2) The person who can help is the one who installed the new CU - get him back in to sort it.

DOES MY HEAD IN WHEN PEOPLE POST IN CAPS.
You need to get the sparks back (if you still trust him).
Having a Oven, Hob and shower all on the same RCD may be overloading the RCD which is likely rated at 80 amp.
Very high, continuous loads must be split across the 2 x RCD's- alternatively put on the direct side of the board with the circuits own RCBO.
If you'd like to post a picture of the fuse board / CU with the labelling and RCD / MCB's photographically clear we can offer further appraisement.

But that will not cause an RCD to trip. An RCD does not have an overload function.
An RCD (RCCB) doesn't detect overcurrent, my guess is either a cummulative effect of earth leakage from all of the said items or there is a N-E fault somewhere and loading up the CU with heavy loads is allowing enough current to pass to trip the RCD.
Lights and sockets should be split between the two RCDs so you don't lose all your lights should something trip, preferably a lighting circuit and a socket circuit in the same area should be on different RCDs.
Either way you need to have the installation looked at by a pro.

WHY IS IT HARDER TO READ TEXT IN CAPITALS? somehow it's easier on the eye to read the little letters.
