Citadel: The one day festival only began last year, and already it's secured two London exclusives - Sigur Ros and Caribou. It'll also host Susanne Sundor, Lianne La Havas, Cat's Eyes and more.
Field Day: PJ Harvey. Need we say more? Alright then, James Blake, Kelela, Skepta, Little Simz, Beach House, Mystery Jets...
Wireless: OK, so the Finsbury Park festival hasn't had the best reaction to its first batch of artists, but there's plenty of gold in there - Lady Leshurr, Petite Meller and Craig David, for example.
Camden Rocks: The Libertines' Carl Barat, Billy Bragg, We Are The Ocean and hundreds more are set to play the North London festival.
Meltdown: Elbow's Guy Garvey is curating the festival this year, which takes place at the Southbank Centre - and his line-up includes Laura Marling, I Am Kloot, Femi Kuti and Connan Mockasin.
Lovebox: The Victoria Park festival - which was founded by Groove Armada back in 2002 - is going to host the newly reformed LCD Soundsystem this year, as well as Major Lazer.
OnBlackheath: This one takes place in September, just as summer is starting to come to an end. Primal Scream and Belle & Sebastian will headline, and they'll be joined by the likes of James, Roisin Murphy, Lonelady and SOAK.
British Summer Time: The Hyde Park extravaganza is more a summer-long event series than a festival. Or, perhaps, a series of day-long mini festivals. Among the headliners are Florence + The Machine, Massive Attack, Stevie Wonder and Carole King.
Fold Festival: Chic's Nile Rodgers is bringing the pan-genre festival to South London. With a number of themed nights and acts booked personally by Rodgers, it'll host the likes of John Newman, Alison Moyet, Angie Stone and - of course - Chic.
Sunfall: This is another brand spanking new festival, taking place in Brickwell Park on one day in July. "Party together by day, go your own way by night at one of our many late-night club sessions," reads the festival's website. The line-up's pretty great.
Caught By The River Thames: Taking place on the northern banks of the Thames, the festival celebrates the best in music, arts and the natural world. Low, Super Furry Animals, Beth Orton and Gwenno are set to perform, while Kate Tempest and Chris Packham are among those set to speak.
South West Four: The Clapham festival has so far announced Knife Party, Rudimental, Dizzee Rascal, Chemical Brothers and many more.
