It began in 1917 as the Sunbury Research Station. Research began with the employment of two chemists to look into the "viscosity of "fuel oil for the "Navy in the "First World War, and the production of "toluene. In the 1920s research took place into "cracking, at the plant at "Uphall in "Scotland ("West Lothian). The first new building opened in July 1931. 76 staff were there in 1929, 99 in 1934 and 197 in 1939.
By the 1950s, BP Research was in a 39-acre site in Sunbury. "Geophysical research had also taken place at "Kirklington Hall Research Station in "Nottinghamshire, until 1957. Around 1958, the site was expanded with a new Physics laboratory and five other buildings. A "Linear electron accelerator was installed. By early 1958, Kirklington Hall had been sold.
Products that the "British Petroleum Company made in the 1950s were BP Motor Spirit and BP Energol (visco-static "motor oil). But Britain would not produce much oil of its own until the mid-1970s when "North Sea oil arrived at the "Forties Oil Field.
Three new buildings were built from 1998 as part of Phase 1. Since 2001, four new buildings were built as part of Phase 2.
The retail division of BP UK is at Witan Gate House. BP employs around 15,000 people in the UK.
