Minimal start up costs, cash in hand and no licence necessary, window cleaning sounds like a tempting option to recession victims or immigrants wanting to start a new life. In fact it's been described by one insurance company as the most dangerous job in Britain and the battle for pitches can be fierce and furious.

In the spiritual home of George Formby Steve faces his biggest challenge, gaining a head for heights at the top of Blackpool tower and testing his new found skills on the oldest window cleaner in Britain, Alan Forest.
