Keane have split to focus on other projects.
The 'Somewhere Only We Know' group are calling it quits, with singer Tom Chaplin said to be keen to start a solo career.
An insider told The Sun on Sunday newspaper: "Tom's been wanting to make a solo album for a while but has been busy on tour with the band.
"Now he's got some songs written and has put a plan together to release a solo record soon."
As the band - whose line-up is completed by Tim Rice-Oxley, Richard Hughes and Jesse Quin - look to the future, they will also be happy to have more time to relax with their families.
The source added: "Every one of their four albums has gone to number one [in the UK].
"They haven't fallen out and will stay close mates. But they've decided it's time to quit at the top and spend time with their wives and families."
Last night a spokesman for the band confirmed the break-up, revealed their 'Best Of' record will mark the end of the group as they explore other projects.
He commented: "Keane are taking a break after the 'Best Of' to pursue their own projects."
