Career: The programme was an instant hit when it first broadcast in 1998 and made stars of Walsh and fellow expert Charlie Dimmock. Tommy took an even bigger role on the show after Titchmarsh quit in 2001. Although Ground Force is the biggest show he's been involved with, he's appeared in various TV programmes, including the series Housecall, Space Invaders, Our House, and Trading Spaces. In 2002, viewers saw him battle his weight on Celebrity Fit Club, and he's also written several books, including Tommy Walsh's Practical Garden Projects and DIY Survival.
