The album entered the UK album chart at 73 and quickly dropped out again (it originally entered the lower regions of the Top 200 in its debut week, but these placings are not officially recorded for statistical purposes). It re-entered at 66 a few weeks later, and its rise was both surprising and unique for a new album on the UK charts. It improved every week for four weeks before peaking at number 36, then dropping down as low as 63 again. It then resumed a somewhat meteoric rise, culminating in a peak of number seven before slowly shifting back down. The publicity surrounding Tunstall's Mercury Music Prize nomination sent it back up the charts to an eventual peak of No. 3, after which time it became a Top 20 mainstay for the rest of 2005. It dropped out of the Top 10 in the 61st week, and has dropped continually since, before ending its run at 72 weeks. After a several month absence, the album returned at No. 66 for a 73rd non-consecutive week in August 2006.
The singles from the album became increasingly more successful, with "Other Side of the World" spending almost five months on the chart and "Suddenly I See" remaining in the Top 40 for 10 weeks. The album's next single, "Under the Weather", entered the chart at No. 39, while the fifth and final single, "Another Place to Fall", became Tunstall's first single to miss the Top 40 after more than 1.3 million copies of the album had been sold. In total, Tunstall has spent 133 weeks so far on the British charts.
The album was certified 5× platinum by the Irish album chart selling about 75,000 copies, and shipping 1.5 million copies in the UK, certifying it 5× platinum there as well. It was also certified platinum in Canada in January 2007. Worldwide, the album has sold 2.6 million copies.
