changing cu with no cpc in lighting circuits

[flukey]

hi all,
got a cu to change on mnoday where both lighting circuits have no cpc.

done a few before and nearly always because home owner wants to keep price to a minimum

i obviously mark it on eic and correctly label the cu so it all complies.

just wondered what others thought regarding this scenario as im not turning any work away at the moment

the elecsa website had a good download manul on exactly this subject. Look at right hand sise of home page click downloads. There is lots of info there.

Silly question possibly, but would the patress screws become live if a loose feed came out of a terminal and touched the metal back box?

i will be changing the switch plates for the ones that have the white plastic push in covers that hide the screw heads so this isnt an issue

I know this may sound a bit thick
But I thought generally the regs prevent us leaving an installation less safe than it was previously.

I know what the ECA guidance is on earthing to lighting circuits - but wouldn't installing a new CU with RCD protection actually make the installation much safer than before?

Although I know that the entire installation should be tested before installing the CU, I thought that the EIC would cover the CU work only??

This isn't a major problem for me as I will just follow the ECA guidance.

I just wondered whether anyone could explain???

Cheers
