Copenhagen was selected as the chosen city after Denmark's Emmelie de Forest won in 2013 with 281 points after a performance of her song Only Teardrops.
As a member of the 'Big Five', the United Kingdom automatically qualifies for a place in the final, along with France, Spain, Germany, and Italy.
The UK's entry, female singer-songwriter Molly Smitten-Downes who goes by the singular Molly, was selected to perform by the BBC, and the 26-year-old Leicestershire-born singer penned the track Children of the Universe herself.
Molly said: "To represent the United Kingdom in such a huge competition, not only as a singer and performer but as a songwriter is an unbelievable honour.
"I hope I can do us proud," she added.
Bookmakers have confirmed that the song has been receiving a record number of odds, with a spokesperson for Paddy Power saying: "Patriotic punters are Smitten with Molly - we haven’t seen this level of support for a Brit in years."
He continued: "If the money continues to pour in like this, we could be facing a record Eurovision payout should she win."
The 2014 Eurovision Song Contest will air on BBC One on 10 May and the UK's commentator will be Graham Norton.
