He was described as having an athletic appearance at the time of the murders due to regularly going to the gym. Port also briefly appeared on an episode of the television show MasterChef. He lived with his parents until his early thirties, then lived alone in a flat in Barking, London, and worked as a chef at a Stagecoach bus depot in West Ham. A former romantic partner of Port's described his personality as childish and gave that as the reason for ending their relationship. After leaving school, aged 16, he went to art college, but it proved too expensive for his parents and he spent two years training as a chef instead. His neighbour described him as having a peculiar, childlike personality, exhibiting odd behaviour as a grown man, such as playing with children's toys. Former teachers also described Port's personality as 'quiet'. He was described as being a 'loner' and was often bullied at school during his childhood. When he was a year old, his family moved to Dagenham in East London, where he grew up and where his parents still live.
