I now have a way of identifying automatically any changes to fta channels at 28,2/28.5E. Thanks to Adrian at AVforums who found a way to extract the data.

Example of changes made between the 11th July 2014 and the 16th July 2014

CBBC HD 10847 23000 V Changed To 11464 22000 H , Smooth 12610 22000 V Changed To 11584 22000 H , 6370 10773 H Deleted , Kix+ 11307 V Deleted , POP+1 11307 V Added , Sky 3D 12324 V Added , Sky 3D 12324 V Added ,

Would anyone be interested in a thread detailing these changes ?

Mainly of interest to non-freesat users, but may identify changes to the Freesat line up where a channel affected doesn’t appear on my box due to the postcode used.
