Local Government Reorganisation
Why we don't yet know when Hertfordshire next votes
Hertfordshire sits in a two-tier county area under review for Local Government Reorganisation following the English Devolution White Paper (December 2024). The county council and its districts are expected to be replaced by one or more new unitary authorities. Until the Statutory Instrument is laid, the next election date is not in our gift to guess.
We'll flip this page from TBC to a confirmed date the moment the SI publishes.
