New fuse box installed, tripping!

Recently had a new fuse box installed, apparently we had a very old system that wouldn’t pass the safety check.

Had no problem with the old system, but the new one has tripped the sockets/cooker, the lights work ok.

Ive unplugged every plug and I’ve tried flicking the sockets and cooker switches on the board off and trying the tripped switch again and it won’t go back on. Also if I turn the lights off and try the tripped switch that’s meant for the sockets it will go on till I turn a light on and it trips again! Surely this shouldn’t be on the same circuit?

Only had this installed a few days ago, and the electrician can’t come back till tomorrow. Any help?
