Frodsham lies within the administrative area of Cheshire West and Chester Council (CWaC). Two councillors are elected from the Frodsham ward to serve on that Council. The Frodsham ward has the same boundaries as the Town's own parish boundaries. The current (2023) Councillors are Cllr Mike Garvey and Cllr Lucy Sumner.
Frodsham Town Council is the local council or parish council for Frodsham. This council is made up of 16 councillors. The town councillors are elected from one of four parish wards called Waterside Ward, Lakes Ward, Overton & Five Crosses Ward and Castle Park Ward. Four Councillors are elected from each ward.
The then Frodsham parish council resolved to style itself a town in 1992. From 1992 to May 2012 the chairman of the council has served as the Town Mayor but using the courtesy title of 'Mayor of Frodsham'. However, strictly, the chairman is only entitled to be known as 'Town Mayor'.
In April 2012 the council resolved to split the roles of chairman and Mayor of Frodsham and separate votes are now held for each position. The council also resolved to create a convention offering the mayorship to the councillor who had served the longest since last being Mayor, or having been first elected regardless of any political or personal affiliations.
