The 2023 Guildford Borough Council election is scheduled to take place on 4 May 2023 to elect members of Guildford Borough Council in England. This is on the same day as other local elections.
The election will be contested on new ward boundaries, due to a periodic review by the Local Government Boundary Commission for England. The council size will remain unchanged at 48 councillors.
There have been changes to the political make up of the council since the 2019 election. In the May 2021 local elections three by-elections were held simultaneously to fill vacancies on the council (two due to resignations, one due to the death of a councillor). However, each seat was won by the same party which has won it at the 2019 election. Subsequently, in November 2021, a Liberal Democrat councillor defected to the Conservatives, taking them to 10 seats on the council and reducing the Liberal Democrats to 16.
Additionally, the sole Green party councillor chose to sit as part of the R4GV group on the council shortly after the May 2019 election, but continues to be a Green party councillor.
Going in to the election, the council administration consists of a Liberal Democrats and R4GV coalition, with the Conservatives forming the main opposition party.
