Can the RCD protection be provided locally (i.e. by replacing the
sockets with RCD ones)

Yes, provided the RCD sockets have suitable characteristics (I
imagine at he ones that are sold do have suitable characteristics).
This is in many ways better than RCD(s) at the consumer unit.

Ta. That's the answer I like.
Available units (Screwfix ranging from £20 to £50) all have 30mA and at
least one is spec'd at 30ms (regs say 40ms).
