Does it have cavity wall insulation? If this is badly done it could cause all of those problems

The survey does say it has cavity wall but not sure what's causing the partial bridging 

The property has  'cavity wall insulation' (an after market added insulation)? If so then you need to have that investigated, there have been so many damp problems caused by poor quality installation. You can drill a hole in the brickwork to see what type insulation added and if it's solid rather than the polystyrene ball type with air spaces I would bet that's the cause

Option 3 and perhaps No. 2 where ground levels run towards the house.

Option 1 is just a waste of money. It just covers the symptoms for a few years without addressing the root cause.

I have cavity walls on the lower half of *this house. In a couple of spots, there is crap bridging the gap between inner & outer leaf (snots of mortar & small bits of rubble) dating from when the house was built. For the most part, it hasn't caused any issues. Did have problems with damp in the kitchen, but after fixing a downpipe/drain and reducing ground levels, that has cleared up (cheap fix too).

What would you estimate option 3 costing in this scenario? Tbh driveway is dated

Depends on how much of the work you are prepared to do yourself. If you're willing to do all the grunt work, maybe £300-500 to cover equipment hire and waste disposal. Or get a company that does ground works in to remove all the nasty concrete and perhaps £2000.
