Note it is also still allowable to have circuits without RCD protection.
However one has to ensure that the cables are not liable to damage. That

some sort (e.g. metal conduit, or via a metal screened cable)

Or run the cables on the surface: AIUI it's only for cables buried 50mm
the RCD becomes necessary.
