The federal party HQ is also used by the English Liberal Democrats and, off and on, by London Region Liberal Democrats as well as various party organisations.

The previous party HQ was at 8-10 Great George Street in Westminster. The last but one Liberal Democrat HQ at 4 Cowley Street had been the party’s HQ since its formation in 1988 when the Liberal Party and the SDP merged. Prior to that it had been the SDP’s HQ.

The Cowley Street building is a lovely Grade II listed building, originally the London HQ for the North Eastern Railway Company. However despite an extensive refit just before the 2001 general election, which saw many internal walls removed, it always struggled to be a good quality modern office. This was because the combination of listed features and the old layout meant the the working space was split up into too many smallish offices on different floors. This hindrance to people working together effectively in teams was always a big problem for the Liberal Democrats. Perhaps unsurprisingly, therefore, the building has since been converted into a luxury residential property.
