The group, who recently announced the LP's title as Above The Noise, will send fans a copy of the LP when they subscribe to their new website 'Super City' next month.
"We've always wanted to be a bit more innovative and do things differently," Tom Fletcher told X.
The singer also revealed that members will have to pay a monthly or annual subscription fee to use the site, which will give them access to demo recordings and priority passes to their live shows.
He continued: "We haven't ironed out the details yet, but it'll be about £6 a month or £40 - 50 a year. There's the music, plus new content every week - live shows, song demos, priority tickets to gigs... and will have a chance to hang out during soundchecks.
"It's about rewarding the fans. People worry about things leaking on the internet but we thought, why not just leak it ourselves?"
The band gave their last album, 2008's Radio:ACTIVE, away for free in the Daily Mail.
McFly launch their 'Super City' website in early October.
