The drum and bass DJ has managed to knock Sunday's number one - Jason Derulo's 'Don't Wanna Go Home' - down to four, while new entry 'How We Roll' by Loick Essien and Example's 'Changed The Way You Kiss Me' sit at two and three respectively.
Beyoncé rounds out the top five with 'Best Thing I Never Had', and Ed Sheeran's 'The A Team' and Calvin Harris's 'Bounce' linger just outside at six and seven.
Adele continues to edge even closer to the top ten with new single 'Set Fire To The Rain', which moves up seven places to 14, while David Guetta's 'Where Them Girls At' re-enters the top 20 at 19 following the release of the music video last week.
Further down the chart, two new entries come from US rapper Mann, who lands at 28 with single 'The Mack', and Peter Andre, whose 'Perfect Night' debuts at number 31.
The highest new entry is Beverley Knight's Soul UK, which currently sits at number six. Selena Gomez and the Scene's third effort When The Sun Goes Down enters the chart at number 13.
