Lucy Alexander was born on 3 April 1970 in East Dulwich, London, England. She grew up with her family in London and has an older sister.

She studied drama and dance at the London Studio Centre, which led to early appearances in entertainment, including a role in a music video before moving into presenting.

Alexander rose to prominence in 2003 as an original presenter of Homes Under the Hammer on BBC One, co-hosting alongside Martin Roberts. The show follows property auctions and renovations and became one of the BBC’s most popular daytime programmes.

She remained on the show for 13 years before stepping down in 2016 to pursue other projects, though episodes featuring her continued airing until 2018.

She now works on A Place in the Sun and lives in the UK with her husband and children.
