Purden is one of the regular presenters of the BBC's Cash in the Attic. In the programme, the presenter visits a family's home to find out what they need to raise money for. They then explore the home to find items that may be taken to auction, which are valued by experts. Before this, he presented Series 1 to 3 of Channel 4's Room For Improvement, a home renovation show.
Purden appeared in programmes with TV personality and self-described psychic medium Derek Acorah. In 2005 he presented Derek Acorah's Quest for Guy Fawkes, which attempted to discover what happened during the Gunpowder Plot of 1605 by contacting Guy Fawkes's spirit. In the first season of Derek Acorah's Ghost Towns (2005–2006), Purden and co-presenter Danniella Westbrook accompanied Acorah to towns and cities throughout Great Britain said to be haunted. These programmes were produced for Living TV.
Purden has done television work for British Airways TV, RBS, Scottish Television (now STV) and the Travel Channel, and also fronted TV We Love To Hate for BBC Three. Radio appearances include BBC Radio Scotland and LBC 97.3, and he writes occasional travel pieces for the Scottish tabloid the Sunday Mail.
In 2006, Purden played a shopping channel presenter, Clive, selling a Kalashnikov assault rifle, in a cinema advertising campaign against the arms trade for Amnesty International.

By April 2006 Purden had returned to Glasgow's West End after having spent 12 years in London. He said that being back in Scotland was a "breath of fresh air" and added: "Life seemed too hard in London. I needed to be there initially because of my career but now that I'm more established I feel it's going to be easier to commute. I'm elated to be back. In Glasgow, he acquired and renovated two B-listed properties.
Purden lists his other main interests as including food, travel (he speaks fluent Italian) and consumer issues. However, in February 2008 he was branded a kitchen calamity after recording the lowest-ever score on the BBC programme Ready Steady Cook.
