Avherald reports that the AAIB are investigating the event (classed as a Serious Incident)?
If true, then there is no reason why a report won't be issued in the normal way, for the benefit of BA and the wider industry, most likely in one of the AAIB's Monthly Bulletins.
The investigation report may or may not be accompanied by one or more Safety Recommendations directed at BA, though that looks unlikely.
