RCBO

A waterlogged patio light or leak down at the shed could be a bit of a nightmare with all of these sockets on the same RCD, and I wonder what rating it is?

80A

I think the conclusion is, just leave it alone!

Isn't it a worry that the cooker/hob are not RCD protected? but I guess it would have overloaded the RCD.

Only if the cooker isolators incorporate socket outlets, otherwise its no issue at all

Assuming the CPC is terminated correctly. I can't think of many reasons at all why something would not be better protected by an RCD

I can think of plenty. Nusiance tripping being the main one. If I can avoid fitting an RCD to a circuit I will.
