SDC GB Ltd. was a UK subsidiary of Danish SDC (3), which came into use around 2000, and ran an optical disc manufacturing plant in Hayes, Middlesex. SDC DanDisc, the predecessor of Danish SDC, had acquired Swedish CD Plant AB in 1997, including its UK subsidiary CDP UK Ltd.; however the use of CDP UK Ltd. as a disc matrix identifier persisted until early 2000. In January 2005, SDC GB Ltd. was acquired by Thamesdown Software Fulfilment Ltd (Thamesdown/TSF (2)), which was renamed Thamesdown SDC Ltd.
