Bowburn Cassop Old Cassop Old Quarrington Parkhill Tursdale Unlike the ecclesiastical parish of Cassop-cum-Quarrington with Bowburn, the civil parish does not include Quarrington Hill. The civil parish was created in 1887 from the townships of Cassop and Quarrington with boundary changes in 1946 and 1953 (the latter changes moved much of the newly built Bowburn Estate into the parish from Whitwell House). Following a residential development at the north-west corner of Bowburn, falling within the Shincliffe parish boundaries, a small adjustment to boundaries was made in 2014 to bring the development wholly within Cassop-cum-Quarrington. The parish was divided into two wards from the May 2013 elections. The division between the two is marked by the A1(M) motorway.

West Ward, consisting of Bowburn and Tursdale, has 11 councillors East Ward, consisting of Cassop, Parkhill, Old Cassop and Old Quarrington, has 4 councillors. As of 2019 the majority of councillors are members of the Labour Party.
