Originally from South East London, he lives in an apartment with his girlfriend Freya Nightingale. From 2014 until 2019, he lived in "Sidemen House" alongside JJ, Vik and Simon. Josh is the oldest of the Sidemen and has known Tobi Brown since secondary school.
Josh gained an A* in GCSE Business Studies. This could explain why he is good at organisation and hosts the majority of group gaming sessions that the Sidemen take part in. Josh is, for many reasons, viewed almost as the "leader" of the group - despite them working together as a team the majority of the time. Josh is also the oldest Sideman which could also explain this fact.
Josh studied Digital Film Production at Ravensbourne University from 2009 to 2012. Josh was supposed to release (but never did) a Call of Duty montage called Illuminate in 2012. He has said that JJ stated that he will get a tattoo of something if Josh did make Illuminate, which gives him an incentive to make it. As of 2019, seven years after the original announcement, Illuminate is nowhere to be seen.
Josh has three channels; his main channel is called Zerkaa where he makes real life videos, vlogs, challenges etc , his second channel is called ZerkaaPlays where he uploads gaming videos and his third channel is ZerkaaClips where he uploads Clips from his Twitch Streams.
He's also a part of the Sidemen channel and the MoreSidemen channel where he makes videos with the whole Sidemen group.
