Kilbirnie and Beith was one of the 10 wards used to elect members of North Ayrshire Council. Created in 2007 following the Fourth Statutory Reviews of Electoral Arrangements, the ward elected three councillors using the single transferable vote electoral system. As a result of the Islands (Scotland) Act 2018, the ward was abolished in 2022.
The area was politically split after each election returned one councillor for both the Scottish National Party (SNP) and Labour as well as one independent councillor.
In 2018, the Scottish Parliament passed the Islands (Scotland) Act 2018 which included provisions to improve the representation of island communities on councils. As a result, an intermediate review of the boundaries in North Ayrshire was carried out. The review coincided with the introduction of the Scottish Elections (Reform) Act 2020 which allowed for the creation of five-member wards. This proposed that three wards – Dalry and West Kilbride, Kilbirnie and Beith and North Coast and Cumbraes – be replaced by two new wards named Garnock Valley and North Coast. The proposals for North Ayrshire were subsequently approved by the Scottish Parliament and the ward was abolished in 2022.[3][4]
A by-election arose in the Kilbirnie and Beith Ward following the death of SNP councillor Craig Taylor. Anthea Dickson held the seat for the SNP on 11 December 2008.
