Disagree. Least likely to be problems doing EWI on a solid wall. With cavity there's a lot that can go wrong in terms of moisture and I think much of what has already been done has caused a lot of damage to the existing buildings. Although it's also cowboy retrofit territory (see also spray foam in the loft, snake oil rising damp solutions).
