BOLDU was formerly the Birmingham Open Learning Development Unit, an Open Tech project that was established in 1984 at Garretts Green College, now part of South and City College, Birmingham.
The original buildings in Garretts Green were sold for redevelopment around 2010. BOLDU became a Limited Company following the 1992 Act which removed FE colleges from Local Authority control. It ceased trading in 2009.
The domain name boldu.co.uk is now owned by JME Associates Ltd, whose Lead Partner, David Evans, worked for BOLDU between 1984 and 1986
