On 4 December 2011, at Anna Maria Island in the U.S. state of Florida, Cash married Sara Davies (born 1957), they had originally met in 1989, and went on to appear on his BBC radio show where she was called 'Emily Email' and became a co-presenter.

[13] Cash was cremated, and in August 2017 his ashes were scattered by fellow DJ Johnnie Walker off the Harwich coast.
