Sam Fender and Olivia Dean’s collaborative single ‘Rein Me In’ has achieved a historic milestone by becoming the longest-running British Number One single of all time.

The track, which first entered the UK charts in February 2026, has spent 16 weeks at the top of the chart, surpassing the previous record of 19 weeks set by Ed Sheeran’s ‘Thinking Out Loud’ in 2014.

The song’s success is attributed to its unique blend of Fender’s storytelling and Dean’s vocal artistry, which resonated with audiences across the UK.

The track’s 35-week climb to Number One also broke the record for the longest ascent to the top, while its 55 consecutive weeks in the UK top 40 make it the longest consecutive top 40 run in history.

The achievement has been celebrated by industry leaders, with Ben Mortimer of Polydor Label Group praising the song’s sustained success and Jo Charrington of Capitol UK calling it ‘the duet of the decade.

’ The single’s longevity also marks it as the only non-Christmas single to spend a full calendar year in the UK top 40, further cementing its place in music history.
