The highway code Road markings (publishing.service.gov.uk) doesnt have them listed... I've always assumed that they are demarking the edge of the main carriageway/start of the side road and so are purely for practical purposes

This was really my reason for asking, because it doesn't seem to specifically mention them. It talks about the double dotted at the junction, single dotted in the middle of the road and about their use as markings for parking spaces for example. But nothing specific.

I was wondering if there were rules or advice about crossing them? Because there don't appear to be any..

Isn't it explained at the foot of page 65 in the "Know your signs" booklet referred to by Car_54 in the post before yours?  He's given a link to it.

Its purpose is to mark the edge of the carriageway - apparently.

Well as it's clearly a junction you are highlighting. 
Which side of the road do we drive on?

So if coming up to a junction, you should not be crossing the single lines as you would be on the wrong side of the road.

Same as when you turn into a junction you cross over the single dotted lines (as highlighted) and not the double ones.

With respect, that's not the question asked. OP is asking what function the single row of lines serve

To indicate which side on the junction you turn into.

That could just as easily be indicated by having NO dashes on that side, hence I don't believe that is the intended purpose of that row of dashes. (It may be a secondary benefit, but not the prime purpose).

On narrow roads (less than 2.75m to the centre) the double give-way line extends across the whole width of the road. Would you really not know which side to enter?

So the dotted white line across the whole width of the road is merely to indicate an alternative road but presumably a requirement to have caution when crossing this line, that it is safe to do so.

No, the broken line highlighted by the OP merely marks the edge of the major carriageway. caution needs to be exercised when entering the minor road, whether or not there is a line.
