Rich House, Poor House

9pm, Channel 5

Charismatic millionaire business trainer Mark Harvey and his family swap homes and lives with single mother Billie Thompson and her mum Deb. Mark has a property portfolio worth millions of pounds and hundreds of dedicated followers flock to his training seminars. Billie’s life could not be more different – bringing up two children on her own, she is thousands of pounds in debt and survives by dipping into cleaner mum Deb’s hard-earned savings.
