The chancellor of the United Kingdom typically lives at 11 Downing Street in London, which is the official residence of the Chancellor of the Exchequer. However, not all Chancellors have chosen to reside there for the entire term, and some have lived elsewhere or used the flat above Number 11 only part-time or as needed. In practice, it is the customary official residence, but it is not an absolute requirement for every chancellor to live there for the full duration of their tenure.
