Hello ,this comes up alot after a new fuseboard has been fitted as they are very sensitive to picking up a fault , if the oven and grill work fine and its just a certain ring that trips the rcd the ring is definitely faulty.
Any new circuits must be rcd protected and the fan in the bathroom must be ,both these could have separate rcd protection instead of changing the fuse box , if you have rcd protection i don’t see why it would need changing .
On average it would cost 120 pound
Yes it has to done to part p which has to be signed off by a registered electrician
It wouldn’t need to be replaced unless you wanted to add new circuits which would need to be upto the current regulations but separate rcds would be adequately satisfiy regulations
