His first book, Wiffle Lever to Full!, first published in 2009, is a mix of travelogue and memoir, talking about his childhood love of science fiction, revisiting it as an adult by attending a number of fan conventions and recording the experience.

He also writes for the magazines Doctor Who Magazine, and Electronic Sound.
In 2018, together with the writer Andrew T Smith, he co-wrote and performed in the show Summer Winos, about the television show Last of the Summer Wine at the Edinburgh Fringe, and subsequently on a national tour into 2019.
