Someone please help - I'm at my wits end.

This happened with my extension - as someone has said above, he has skimmed the existing surface - I just bought larger skirting boards. Think they were 5 inches, cheap as chips.

larger/taller skirting boars, either fill gap with some easyfill or fix on packers or with expanding glue foam, just to be on the safe side nice line of decorators caulk where top of board meets wall and clear excess with damp sponge  to keep it neat ( prevents cracking in future ) .

would another solution be to fit a rounded moulding above the existing skirting board of sufficiant width to cover the widest of the gap? once painted it will just look like a taller one piece skirting board and maybe an easier fix as the moulding can be attached to the new plaster with something like 'no nails'.

What kind of flooring are you planning to fit?  If carpeting then get taller skirting.  If hard flooring then don't fit the skirting until after the flooring.  Underlay + flooring should take up the extra space. 
Use pieces of wood behind the skirting to bring it out level with the surface of the plaster.

jesus christ no.
options are either get some taller skirting.
or plaster further down to the floor so the skirting you have covers it. not right to the floor though

Please don't do this, that would look like such a bodge

Simplest solution is to finish off the plaster to 10mm off the floor then you can fit any skirting you like
