Tyler (Philip Whitchurch) is Janet and George's eccentric scouse neighbour. Aside from family, he is the only person who knows George's real identity, but often seems to have his own even more bizarre ideas and theories about the universe. For instance, he often claims that Gandalf, Frodo, and other fictional characters are staying in his flat. George initially denies Tyler's claims that he is Thermoman, but later begins to accepts that Tyler knows (mainly because no one would believe him), and gives him a job as his assistant in the health shop, replacing his former assistant, Avril.
