lighting circuit with no earth

Must admit. I remember being taught it at college some 15yr ago!

 

In college in your forties!, cool Lec, lol

 

I remember doing it in the 80s ie 15th edition!

 

Some good advice here Kelvin. Had a similar scenario on a flat refurb I did earlier this year. The flat was going up for rent so spark suggested partial rewire, not so much for the reason that it 'broke the rules' but since a bathroom extractor and some new metal light fittings were going in meant that he would had to record that no earth was present. A** covering stuff really.

Anyway, all old cable pulled up through sheathing fine so pretty straightforward and quick. Much better and probably easier than running separate earths.
