The Joint Terrorism Analysis Centre (JTAC) is an all-source intelligence organisation closely related to the United Kingdom Security Service which provides advice to the British government and firms within the Critical National Infrastructure on terrorist threats. Operating from Thames House on Millbank in central London, it provides regular assessments to government departments, major companies and institutions, predominantly in the transport, financial services, utilities and telecommunications industries.

Thames House is an office building in Millbank, London, on the north bank of the River Thames adjacent to Lambeth Bridge. Originally used as offices by Imperial Chemical Industries (ICI), it has served as the headquarters of the United Kingdom's internal Security Service (commonly known as MI5) since December 1994. It also served as the London headquarters of the Northern Ireland Office (NIO) until March 2013.

The Security Service, also known as MI5 (Military Intelligence, Section 5), is the United Kingdom's domestic counter-intelligence and security agency and is part of its intelligence machinery alongside the Secret Intelligence Service (MI6), Government Communications Headquarters (GCHQ), and Defence Intelligence (DI). MI5 is directed by the Joint Intelligence Committee (JIC), and the service is bound by the Security Service Act 1989. The service is directed to protect British parliamentary democracy and economic interests and to counter terrorism and espionage within the United Kingdom (UK). Within the civil service community, the service is colloquially known as Box, or Box 500, after its official wartime address of PO Box 500; its current address is PO Box 3255, London SW1P 1AE.

Imperial Chemical House is a Grade II listed building situated on Millbank, London, England, near the west end of Lambeth Bridge. It was designed by Sir Frank Baines in the neoclassical style of the inter-war years, and constructed between 1927 and 1929 as the headquarters for the newly created Imperial Chemical Industries (ICI). Thames House, the next building south along Millbank, across Horseferry Road, was also designed by Baines and constructed at the same time. Both buildings were built to house offices for the newly formed ICI, created in 1926 after the mergers of Nobel Industries, United Alkali, British Dyestuffs and Brunner Mond. The buildings were completed in the aftermath of the 1928 Thames flood, and Lambeth Bridge was also replaced. Imperial Chemical House was divided in 1987 to create Norwest House at 9 Millbank, and Nobel House at 17 Smith Square. ICI moved out in the 1990s.

Transport House was the headquarters of the Transport and General Workers' Union (T&G), and also originally of the Labour Party, the Trades Union Congress, and the Workers' Travel Association. The term "Transport House" was once a metonym for both Labour Party Headquarters and the T&G. The building located on Smith Square and Dean Bradley Street, London, England was actually owned by the T&G and officially opened in May 1928. The T&G started to occupy it from 1926, moving from their first headquarters in Matthew Parker Street. The TUC moved out to Congress House between 1956 and 1958. The Labour Party moved out in 1980, transferring its headquarters to what later became known as John Smith House. The T&G remained until the 1990s, when they moved to a modern building on Theobalds Road, Holborn, which is now also known as Transport House. The original building is now called Local Government House and houses the headquarters of the Local Government Association and a conference centre. The local headquarters of the T&G in a number of other cities were also called Transport House.

The Delegation of the European Union to the United Kingdom, formerly known as Representative of the European Union (specifically the Representative of the European Commission and the Representative of the European Parliament) in London are the diplomatic missions of the European Commission and the European Parliament in the United Kingdom.They are both located in Europa House, 32 Smith Square. The building was formerly the Conservative Party's Central Office from the late 1950s until 2004 and was famous as the place where the Conservatives planned and celebrated their election victories. It was then left vacant until 2009 when the EU chose it as their new London office, along with a new personalised postcode – SW1P 3EU. There was some criticism of the amount spent by the EU in acquiring and updating the interior of the building, with £20 million spent on purchasing the property and £5 million on revamping the building. It allegedly included the installation of bomb and bullet-proof windows.As a result of the United Kingdom's withdrawal from the European Union on 31 January 2020, the Representative of the European Union was replaced by the Delegation of the European Union to the United Kingdom Since February 2020, the Ambassador of the Delegation of the EU to the UK has been João Vale de Almeida. The representative is referred to as ambassador, however in the United Kingdom full diplomatic status is only given to representatives of sovereign states.

St John's Smith Square is a redundant church in the centre of Smith Square, Westminster, London. Sold to a charitable trust as a ruin following firebombing in the Second World War, it was restored as a concert hall. This Grade I listed church was designed by Thomas Archer and was completed in 1728 as one of the so-called Fifty New Churches. It is regarded as one of the finest works of English Baroque architecture, and features four corner towers and monumental broken pediments. It is often referred to as 'Queen Anne's Footstool' because as legend has it, when Archer was designing the church he asked the Queen what she wanted it to look like. She kicked over her footstool and said 'Like that!', giving rise to the building's four corner towers.

The UK Holocaust Memorial is a proposed memorial and learning centre to preserve the testimony of British Holocaust survivors and concentration camp liberators and to honour the Jewish victims of the Holocaust and other victims of Nazi persecution, including Roma, LGBT, and disabled people. The government originally planned to build it in Victoria Tower Gardens, a Royal Park next to the Houses of Parliament. This proposal became contentious because of the popularity and nature of the location and because the memorial would take around a quarter of the green space in the park.In July 2021 it was announced that, following a public inquiry, planning permission was granted for the Holocaust Memorial. In November 2021 a High Court judge granted a Planning Stautory Review of this permission.In April 2022 the high court in London overturned the decision to build the memorial in Victoria Tower Gardens. Permission to appeal was also refused.
