Lucy Gannon once worked as a military policewoman, a residential social worker, and a nurse, and lived in a concrete council house with no central heating. She later moved to a converted barn in Derbyshire and now lives near Cardigan, in Wales.
She started, in 1987, to enter the Richard Burton Award for New Playwrights. Her play, Keeping Tom Nice, about a disabled boy whose father commits suicide, earned her the award and a six-month writer-in-residence at the Royal Shakespeare Company. In 1988 Keeping Tom Nice was shown at the Almeida Theatre in London, and in 1989 shown as a BBC TV Screenplay starring Linus Roache.
Gannon has written several single or short run dramas, including Dad, Tender Loving Care, Trip Trap, The Gift, Big Cat, Pure Wickedness, The Best Of Men, The Children.
In 2008 Lucy Gannon criticised the BBC, saying that delays in commissioning programmes threaten writers and producers.
In 1996 she was awarded the MBE for services to Drama, and among her awards are The Eileen Anderson Award, The Richard Burton Drama Award, The Susan Smith Blackburn Award, The BAFTA Cymru, and the Contribution To The Media Award (Women in Film and Television) and, most recently, the RTS Award (South West England) for Best Writer for her film The Best Of Men.
In 2012 Gannon wrote the one-off BBC2 drama The Best of Men which told the story of the first Paralympic Games and starred Eddie Marsan and Rob Brydon. She is the lead writer and creator of the 2013 BBC One drama series Frankie.
