The radiatprs are c 1968-70. Assuming that electrolytic action has
hollowed them out and that they may need replacing, are the copper pipes
likely to be equally affected?

Once you start disturbing something that old and with unknown corrosion
inhibitor history you are asking for trouble if you don't replace the
whole lot in one go. It could well be a nightmare of pinhole leaks
otherwise (shortly after you refill it with fresh oxygenated water).

If there is a Fernox certificate on the CH header tank you might just be
OK, but I wouldn't chance it myself.

Preferably done before you move into the property so that it is easier
to access the pipes and much less disruptive. Living without heating or
hot water is no fun - especially in winter.
