Factual error: In this episode Nick rides the pump. However, being Station Officer, he should be riding the pump ladder. The London Fire Brigade always has the Station Officer in charge of the pump ladder and not the pump (it's the Sub Officer who is in charge of it).
Continuity mistake: On the way to the second shout at the council accommodation, the fire appliance shown is YHV 194T. Whilst this was the pump in the pilot and first series, for the second series, the appliances were GYW 627W and GYW 628W. (00:43:00)
