Tandridge District Council is elected by thirds. A third of councillors are elected every year over a four year period. In year four, Surrey County Council elect all their councillors in one go.
In 2021, due to COVID-19 causing elections to be postponed from 2020, a third of District Council seats (and three vacant seats) were elected at the same time as the County Council. Those elected for District Council will serve a three year term to bring the electoral cycle back on track. Those winning by-election seats will serve out the term of office of their predecessor.
