Audio problem: In the episode A Day Out, the prison minibus has a deisel engine when heard from inside, but when Mr Mackay borrows it to go to the pub it has a petrol engine.

Continuity: In several episodes of the show, Richard Beckinsale's hair changes length and style during individual episodes.

Revealing: In the episode where Fletcher and Godper are assigned to the work party and they get locked into the church, one of the prisoners, Melvin (the hippy) leans against one of the 'stone' pillars of the church, causing it to wobble.
