The Millbank Tower has been home to many high-profile political and other organisations. From 1994 to 2002 the
Labour Party rented two floors in the base at the south of the site, for use as a general election campaign centre. Labour ran its
1997 General Election campaign from these offices; after the election, the party vacated its headquarters at
John Smith House,
Walworth Road SE17, to move to Millbank. Five years later, the £1 million per annum rent forced the party to vacate the tower and take out a mortgage of £5.5 million to relocate to 16–18 Old Queen Street, overlooking
St James's Park, which had 11,200 square feet of open plan premises. The
United Nations also had offices in the tower, but moved out in June 2003, also citing high rents. Other public bodies have continued to occupy the building, including the
Central Statistical Office, the predecessor of the
Office for National Statistics; the
Parliamentary and Health Service Ombudsman; the Local Government Ombudsman; the
UK India Business Council; and the
Ministry of Justice Records Management Service. Between 2006 and 2014, the
Conservative Party based its
campaign headquarters at 30 Millbank, in the same complex as Millbank Tower. Other floors in the tower are or have been occupied by organisations and commercial companies, including the
Environment Agency, the
World Bank (which moved out in early 2022),
Altitude 360 London, foreign exchange specialists World First, the
Specialist Schools and Academies Trust, the
UK India Business Council, the London office of
Medopad,
Canonical Ltd, the
Audit Commission, event caterers Salt and Pepper, Private Food Design, the firm Lewis PR, the London office of the
Open Society Foundations, the
Local Government Boundary Commission for England,
XLN Telecom and
Leave.EU. The building also housed the studios for
RT UK prior to its closure in 2022. From April 2018, the office of the now-defunct
People's Vote campaign was based in the tower. The political party
Reform UK has been headquartered in the tower since February 2025. ==Future==
