ModelAdmin managing the following model...

class MyObject extends DataObject
{
   static $db = array(
      'MyDate'          => 'Date',
   );
   public static $summary_fields = array (
      'MyDateText'   => 'DateFormatted'
   );
   static $casting = array(
      "MyDateText" => 'Text',
   );
   public function MyDateText(){return date('d/m/Y',DateManager::DateToPHPDate($this->MyDate));}
}

I've also done stuff to allow me to search, BUT the issue is that I now have lost the ability to click the column heading in the search results to order the data by that column... can anyone help me with this please?

(I am using 2.4.0, but planning on getting to 2.4.3 in the new year, maybe I should wait?)

Have a look at TableListField->isFieldSortable() - for performance reasons, we can't allow to sort on PHP getters, as we'd need to preload all records before sorting.

Fair enough, I'll take another look at this in the new year when upgrading the latest version, and thank you for offering to help with date issues previously. At the moment it works, but I am sure I can achieve the same results with what feels like hacky code - and I hope to get this right too because I am only formatting the date with the casting the sort I was under the delusion it could be done but it makes sense that it cannot.
