The stand-up won huge critical acclaim for the comedy, which was set in the concrete jungle of a South East London tower block.
He starred as the grumpy Vince, and co-write it with Mark Lamarr and Martin Trenaman.
Both series have just been released available on one £24.99 set, including commentaries by the writers and directors, and an interview with Lock and Lamarr.
But Lock is also offering to answer any questions from Chortle readers about comedy or his career – and those who put the best five questions will receive a copy of the new box set.
