The BA is a charity established under Royal Charter and governed by a Council which forms the Board of Trustees. It is managed by a professional staff, with around 30 people in the national office in the Wellcome Wolfson Building in South Kensington and 12 part-time regional staff across the UK. The 16 scientific Sections of the BA, which contribute primarily to the annual Festival of Science, are run by committed volunteers. So too are the 33 Branches, which organise events and activities locally across the UK.
