By the 1980s, Faith had become an investor and financial adviser. In 1986, he was hired as a financial journalist by the Daily Mail and its sister paper The Mail on Sunday. Faith and business partner, Paul Killik, were the principal investors behind UK television station Money Channel. When the channel closed in June 2002, Faith was declared bankrupt, owing a reported £32 million. English film director and producer Michael Winner stated that Faith was his investment adviser, leading to significant losses on two different investments.
In 1986, Faith had open heart surgery. In 2003, he became ill after his evening stage performance in the touring production of Love and Marriage at Stoke-on-Trent, and died of a heart attack early the next morning, 8 March 2003, at North Staffordshire Hospital.
