Hi There
You use a tight coat of water proof render or a tanking slurry to hold back any damp that is in the walls,then you can thermal board the walls, dot and dab method rather than battens as it will be cheaper and quicker.

old methodologies die out for a reason
remove plaster use tanking membrane and replaster
1. it stops damp permanently
2. it reduces condensation as the membrane has insulative properties
