Episode 14

College lecturer Gillian from Berkshire sets up her lodger Desmond for a visit from a pretend rogue roofer. Roger persuades him that a problem with their solar panel can only be fixed with the addition of a special meteorological clock, which will cost several hundred pounds. But Desmond has engineering experience from his days in the Air Force. Will he be taken in by Roger's flim-flam?

Plus a Hertfordshire man sets up his girlfriend, who waits in for Roger to fix a broken panel in their front door. Will she pay the fortune he wants to charge for inexpensive burglar alarms?

Meanwhile, a quick-thinking bank clerk in Merseyside saves a consumer from a £6,000 rip-off roof repair. Her emergency call to police ensured that the cowboys were caught in the act and convicted.
