In contemporary British English “program” is used for the computation-related senses. “Programme” is used for all the other senses, e.g. a concert programme. Using “reprogramme” in a computation context is very old-fashioned and would be considered nonstandard spelling these days. I suspect this is someone taking BrE localisation too seriously or it’s a non-British person’s idea of what British English is.
