With all the incredibly noisy switch mode supplies and powerline internet
adaptors around nowadays, I think most houses need wiring with screened
cables and possibly undeground as well!

No they don’t, most don’t bother with AM radio anymore.

I seem to recall reading somewhere that in 2 way switching for house

I is mentioned at: http://wiki.diyfaq.org.uk/index.php/2_Way_Switching

What sort of interference are you talking about?

You might also find it very difficult to obtain 4 core and earth. I've
never seen it in terms of house wiring.

But if it is a problem on a two way switched circuit, it would also be a
problem on the common way to wire lighting with a switch drop from
ceiling
rose to switch.
