Age Concern has been nominated as one of the most gay-friendly organisations by the Pink Paper newspaper.
The charity for older people is shortlisted for the award alongside the London Metropolitan Police, Unison, Amnesty International and the Quakers.
It received the recognition from the UK lesbian, gay and bi (LGB) newspaper for its Opening Doors programme, which is targeted at older LGB people.
"We estimate that there are [at least] 700,000 older lesbians, gay men and bisexuals in the UK, who need our services, every bit as much as the rest of the older population," said Gordon Lishman, director general of Age Concern England.
"However, in the not too distant past it has been difficult for them to come forward because of the prevailing prejudice they encountered in society at large."
He added: "It is precisely to counter that prejudice that we welcome opportunities such as this to demonstrate and promote our support."
Winners of the Pink Paper's Readers' Awards 2007 will be announced on January 11th 2007.
