2009 Hertfordshire County Council election

An election to Hertfordshire County Council took place on 4 June 2009 the date of the 2009 United Kingdom local elections. The whole elected council was up for election. The councillors were elected from the 77 wards, which return one each by first-past-the-post voting for a four-year term of office. The wards were the same as those used at the previous election in 2005.

All locally registered electors (British, Irish, Commonwealth and European Union citizens) who were aged 18 or over on Thursday 4 June 2009 were entitled to vote in the local elections. Those who were temporarily away from their ordinary address (for example, away working, on holiday, in student accommodation or in hospital) were also entitled to vote in the local elections, although those who had moved abroad and registered as overseas electors cannot vote in the local elections. It is possible to register to vote at more than one address (such as a university student who had a term-time address and lives at home during holidays) at the discretion of the local Electoral Register Office, but it remains an offence to vote more than once in the same local government election.
