Cracking on external wall

Who can provide me with a QUALIFIED opinion on whether cracking on an external wall is superficial or is likely to be something more concerning and needs surveying?

"Depends on the 'cracking'. Cracking normally gives an indication of its source, it can be ground movement, it can be a drain issue or it can be a lintol failure, quite a few things really so it needs looking at. We sometimes put 'tell tale' markers on and measureme them periodically to assess whether movement is ongoing or stable and always look to clear the cause issue first before cosmetic repainting. So, no one can say definitively without looking at it but whatever it is, is curable."

"It will depend on extent of crack and if it goes through to inside
It also depends on if it goes from a window or door to floor or facia as it could be window or door failing outside ground dropping is a sign of serious movement but a structural survey would determine if serious or minor"
