Are you taking the skirting off the wall first, lay the floor and then
replace the skirting?

Yes - although I will be ditching the current stuff and replacing with new.

If that is the case then the job is easy - lay the floor lay the cable on
top of the floor and then refit the skirting making any exit holes in it
before you do.

This is my question - do I just drill a hole in the skirting, or make little
'notches' in the top face / bottom section where it joins the floor ?? Is
skirting generally flush to the fall throughout its length / height, or can
you buy skirting that has grooves in it already on the rear face that can be
used for this purpose ??

If you are leaving the skirting intact then you will have a problem as you
will have to try and feed the cable into any gap between the floor and
skirting or try and notch the skirting but it will be almost impossible to
bring the cable out from behind it.

See above - no probs.

Hope this helps

Yep - getting there - just a quick question above ....
