Hit40UK was a networked Top 40 chart show broadcasting on around 130 UK commercial radio stations every Sunday from 4pm to 7pm.

The chart continued to be compiled, and a TV version was shown on 4Music, The Box, and Smash Hits, which was renamed UKHot40.

Hit40UK descended from The Network Chart Show which began on 30 September 1984 and which was originally hosted by David Jensen and broadcast on competing commercial radio stations across the UK.

[5] Pepsi ended their sponsorship of the show on 29 December 2002, and the Hit40UK name was adopted on 5 January 2003, but Dr. Fox remained the host until 30 May 2004.

Hirst who during the week hosted the Galaxy Breakfast show in Yorkshire and was enjoying considerable success doing so, had to stand down as presenter of Hit40uk due to objections from Galaxy's rival Yorkshire radio stations Viking FM, Radio Aire and Hallam FM who were due to start broadcasting the chart on 22 October 2006.
