a property can have no earthing (very old) and rcd will provide protection against direct and indirect contact?

No. RCD's are only classed as additional protection (411.3.3).

While lighting circuits without earths can be allowed (with provisions attached) a property with no earths on all other circuits is a re-wire situation. :)
