When does the Vauxhall Insignia need a timing belt change?

I'm considering a Vauxhall Insignia but have always kept away from belt cam engines. I will buy 12-18 months old with up to 20,000 miles and keep it for five years, doing 7000 miles a year. Regardless of blurb, what mileage/age would you recommend the belt change be done, and what else should I get it changed at the same time? In todays prices, what would it cost?
This engine is based on the previous Alfa Romeo 1.9. Obviously most of the shortcomings of that engine have been attended to, but I can't tell you of its long term reliability for another year or two.
