please help

Hi my brother Josh has been away at the caravan with his son and girlfriend . Josh’s friend on saturday went to park his car under Josh’s flat and noticed water running out of the building from my brothers flat, If turns out he has been flooded for nearly a week, flat ruined. personal affects destroyed. The flood was so bad its spread from his flat to the building and running down Liverpool Road. I know everyone is struggling at the moment, but if you can spare a few pounds to replace his floor and furniture it would be greatly recieved.
