An election to the Llandeilo Rural District Council was held in April 1913.[1] It was preceded by the 1910 election and, due to the scheduled 1916 election being postponed due to the First World War, was followed by the 1919 election. The majority of members were returned unopposed.[2] The successful candidates were also elected to the Llandeilo Board of Guardians.
All members of the District Council also served as members of Llandeilo Board of Guardians. A further three Guardians were elected to represent the Llandeilo Urban District.[4]
Three Guardians were elected to represent the Ammanford Urban District which also lay within the remit of the Llandeilo Guardians. All three sitting members were returned unopposed.[2]
In addition, following the formation of the new Cwmamman Urban District in 1912, a further three members were elected to represent that area.[3]
