Series 23 of British television drama The Bill was broadcast from 3 January until 28 December 2007. The series consisted of 92 episodes, and saw the conclusion of two long running-storylines, the disappearance of schoolgirl Amy Tennant and DC Zain Nadir’s undercover drug sting, prior to the return of single-themed episodes, removing much of the serialiased format formally introduced in 2002 under producer Paul Marquess; episode titles also started appearing on screen again from Episode 20 onwards. Several episodes were aired out of production order, most notably the final parts of the six episodes for the Zain storyline. Despite at the time not even being billed for broadcast, and the 'previously' and 'next time' segments not matching the episodes around them, the episodes were brought forward due to heavy demand from the British viewing public. This also meant that the 'previously' and 'next time' segments on the subsequent episodes had to be re-edited to show this, and that two small additional scenes had to be recorded to be placed into Episode 480 to reference the death of PC Honey Harman. For the DVD release, to avoid confusion, these episodes have been renumbered and now serve as 480 and 481, with the following four episodes renumbered to 482–485 respectively.

Series 22 of British television drama The Bill was broadcast from 4 January until 28 December 2006. The series consisted of 91 episodes, as two episodes from the series remain unaired after the master tapes were stolen in a robbery at the show's recording studios in November 2006. Under new producer Johnathan Young, this series saw the programme begin to step away from the serialised format, and return much of the focus to the actual policing aspect of the programme, removing the more 'soap' feel previously introduced by Paul Marquess. Most episodes consisted of two parallel stories running at the same time, much like the initial transition to hour-long episodes in 1998. However, some episodes feature entirely on one story, beginning the move back to single-themed episodes as part of a plan to completely remove serialisation - which did not take place until 2007. The series also saw a large portion of cast changes in the first few months, with a number of characters previously introduced by Marquess being axed to make way for new blood - many of them support staff and non-police officer characters. Young believed that several of the characters introduced by Marquess did not have the longevity of the more well-known characters in the show, and thus decided to give a number of highly recommended up-and-coming actors roles on the show, such as Kidulthood star Aml Ameen.
