The Petroleum Board was established within a week of the outbreak of the Second World War in September 1939. It was based in
Shell Mex House on the
Strand, London. The membership comprised the Chairmen or Chief Executives of most of the petroleum and oil companies operating in the UK. The original corporate membership was the
Anglo-American Oil Company, the
National Benzole,
Shell-Mex & BP, and Trinidad Leaseholds and their associated companies. Other oil companies joined the Board later. The aim of the board was to oversee the import, processing, storage, distribution and delivery of all petroleum products in the UK with the exception of oil for the
Royal Navy. Supplies of petroleum and petroleum products were no longer branded and competition between the oil companies was suspended. The board was acknowledged to have been effective. This prompted the chairman of the Petroleum Board, Sir Andrew Agnew, to write to the press to assert that the Board was not responsible for rationing. He pointed out that this was the responsibility of the Petroleum Department of Board of Trade, and the
Ministry of War Transport. == Post-war coordination ==
