The Conservatives remained in overall control of the council, increasing their majority by one seat. Labour lost three seats, despite its share of the vote actually increasing compared to the 1983 election. The Labour group leader, Ian Mantle, was one of those who lost his seat.[2]

Two by-elections were held on 28 March 1985. The by-election in Cadwell ward was triggered by the death of independent councillor Ron Lodge, and the by-election in Letchworth South West ward was triggered by the resignation of Conservative councillor John Talbot. The SDP–Liberal Alliance won the Letchworth South West seat from the Conservatives. In Cadwell ward the Conservatives won the seat which had previously been independent.[6]
