The standard way out of this problem is a Henley block to split the tails ahead of the CU. Then a switch for the feed to the chalet. Provided there is overcurrrent protection for all circuits in the chalet and the total of the MCBs in the chalet don't exceed the SWA rating then you may not need a fuse or MCB at the house end. Probably best to use a 50A fuse/MCB.
As I said before, cascaded RCDs are safe, if possibly a nuisance. Don't bother with time delay RCDs, they are really only for more specialised applications. Such as on a farm where you might use a 300mA delay RCD as the main switch.
