Continuity mistake: During the last episode of the first series doorman Paddy uses his hair spray to give him fuller locks. But at the start of the second series his hair is back to its normal style even though the second series starts where the first series ended with the club on fire.
Suggested correction: The start of the second series takes place some time after the fire of the first season. Many of the staff of the Phoenix have moved on and got new (proper!) jobs. For example, Jerry is now working for Asda, a job he didn't have before. The spray maine (sic) is, as the name suggests, spray-on hair and would undoubtedly come straight off again the first time it gets wet! Plus after a couple of weeks or months, even a slightly more resilient hair spray 'treatment' would have fallen off.
Revealing mistake: If you look at Les out of Les Alano's' drumming, several time throughout the whole show, you can see he is miming and his stick is not even close to the actual drum.
Continuity mistake: Between series one and two, and even more so in Max and Paddy's road to nowhere, Max's voice changes from really deep to normal depending on the series and sometimes the episode.
Other mistake: How come not one single person at the Phoenix Club knew Max's surname, namely Bygraves, during his time as a doorman? This only came to light in the "Road to Nowhere" spin off.
