Founded in 1981, it plays in Segunda Federación – Group 1, holding home matches at Estadio Pepe Quimarán.

In May 2016, after 35 years of playing in regional divisions, the club was promoted for the first time in its history to the Tercera División.

[2] Estadio Las Huelgas was the first home stadium of UD Llanera.

It competed always in the Regional league except in the 2011–12, after an agreement with Oviedo Moderno CF to be its reserve team in Segunda División.

Llanera came back to Segunda División in 2017, after finishing as runner-up of the regional league and the ineligibility of Oviedo Moderno B to promote.
