The 2026 Bromley London Borough Council election took place on 7 May 2026. All 58 members of Bromley London Borough Council were elected. The elections took place alongside local elections in the other London boroughs and elections to local authorities across the United Kingdom.
In the election, the incumbent Conservatives retained their control of the council, losing seats to the Liberal Democrats and Reform UK. Despite some expectations, Reform did not make expected gains, and their leader, Alan Cook, lost his seat. Labour lost seats to Reform and the Conservatives.
Background In July 2025, Reform UK won their first seat in London at a local by-election in the Bromley Common and Holwood ward. This success, as well as the defection of Conservative councillors Christopher Marlow (Farnborough and Crofton) and Kira Gabbert (Bickley and Sundridge), led Reform to expect large gains in the Borough.
