The constituency consists of the northern and central areas of
East Ayrshire and contains the town of
Kilmarnock and the
Irvine Valley. It does not share the same borders as the former
Scottish Parliament constituency of the same name. There was a
Kilmarnock and Loudoun local government district covering a similar area, from 1975 to 1996. At the 1983 general election, this district was coterminous with the constituency boundaries Under the
Fifth Review of UK Parliament constituencies, the constituency was expanded to include part of the abolished
Carrick, Cumnock and Doon Valley constituency; the boundaries were defined in accordance with the ward structure in place on 30 November 2004. Under the
2023 review of Westminster constituencies, which came into effect for the
2024 general election, the boundaries were unchanged. Further to reviews of local government ward boundaries which came into effect in 2007 and 2017, but did not affect the parliamentary boundaries, the contents of the constituency are now defined as comprising the following electoral wards of the
East Ayrshire council area: •
Annick,
Ballochmyle,
Irvine Valley,
Kilmarnock East and Hurlford,
Kilmarnock North,
Kilmarnock South,
Kilmarnock West and Crosshouse, and a very small part of
Cumnock and New Cumnock. The main towns and villages are: •
