I agree with Buttercupdays and think you should contact your local council with the possibility of a rising water table and ground contamination in mind. Some of that damage does look more like the effects of soil poisoning than disease. I also have honey fungus present and it doesn't cause the growth distortion which is clearly evident in some of your photos, Stuart.
Edit: You could also have a number of diseases present - once a plant is weakened (for example by honey fungus or a rising water table rotting the roots) any number of secondary diseases can take hold.
