The town was an urban district until 1974, when it was merged into the North East Derbyshire district under the Local Government Act 1972. In the 1970s the council achieved brief notoriety due to its refusal to implement the Housing Finance Act 1972 in increasing the rents of council housing: by law the rents should have increased by £1 a week from October 1972. The council was one of several to show defiance against the Act and of three to be ordered to comply by the Department of the Environment in November 1972 (the others being Eccles and Halstead). Clay Cross UDC was threatened with an audit in December 1972. The constituency Labour party barred the eleven councillors from its list of approved candidates. The District Auditor ordered the eleven Labour Party councillors to pay a surcharge of £635 each in January 1973, finding them 'guilty of negligence and misconduct'. Conisbrough UDC faced a similar audit on 19 January 1973.
