Although Capital still has the greatest reach in London at breakfast, Heart's Jamie Theakston has now overtaken Vaughan's show as the most listened to programme in terms of share and hours.
Radio 1's Chris Moyles is the only morning host who is still gaining listeners, as Emap's Kiss and Magic, GCap's Xfm and Chrysalis's Heart all lose breakfast listeners.
Commercial radio has enjoyed an upswing share in audience for the second consecutive quarter, while the BBC's share is again down.
Digital radio listening is also on the rise across the board, with commercial radio enjoying a 65% share in digital hours.
Heart has stolen Magic's crown as the number one station in London while Capital continues to struggle, which it has tried to address with the appointment of new programme director Scott Muller and a new music policy.
Pete Simmons, group head of programmes at Chrysalis, said: "Of course, we're very pleased to be top in London. We've been number one several times before but this time we've got the biggest lead against anyone else."
