SPAID / OEDA's core funding from 1983 to December 2002 came through the administration of Greater London. Initially this was a grant from the Greater London Council (GLC), and from 1986 a grant through the London Boroughs' Grant Scheme, which was set up under Section 48 of the Local Government Act 1985 to continue support for voluntary and community sector organisations operating in more than one borough. From 2000 to 2002, when a new legislative body known as the Greater London Authority (GLA) was established, OEDA received GLA funding. OEDA's subsequent applications to GLA were unsuccessful.
Both the funding applications themselves and the organisation's interactions with the grant scheme administration offer rich insight into SPAID / OEDA's activities and how the organisation evolved over time.
