"Being Human lives on!" said series creator Toby Whithouse. "The response to series four has been terrific. We're thrilled that the audience have taken the new cast into their hearts with such enthusiasm and affection.
"We're delighted to have this opportunity to expand the world further and explore new characters and tell new stories. A heartfelt thank you to all the fans for their unstinting support, and to the BBC for letting us mess up the sandpit for a fifth year."
Details of the new episodes are still being kept under wraps, though both vampire Hal (Damien Molony) and werewolf Tom (Michael Socha) will return.
"In Being Human, Toby has created an extraordinary, funny, touching, supernatural world and I'm thrilled to be bringing it back for a fifth series," said BBC Three controller Zai Bennett.
It has also been confirmed that Lenora Crichlow will not reprise the role of ghost Annie, with a video confirming the character's exit being released on the show's official blog.
"Sometimes, you have to just respect that a story [and] a character has come to a natural end," said Whithouse. "Lenora completely understood that and completely agreed with it."
The actress agreed: "I don't know if there's much more for her to do, if I'm honest. [But] I really will miss playing Annie - she's such a fantastic character to play."
