William lives in Goathland, where Heartbeat is filmed.
Despite playing a heavy smoker in Heartbeat, in real life he doesn't smoke.
William: Being involved in a long-running series hasn't prevented me from accepting other work. I was very lucky in the first two years of Heartbeat to be able to do another series for the BBC, at the same time, playing another policeman. It was fortunate that I was able to do both, with careful juggling of my working days. It's not so easy now but I would prefer to be in this (Heartbeat) than in anything else.
