Rich House, Poor House

Kamil's businesses turn over £3m a year and he makes over £40,000 profit every month, while his partner Francesca runs a successful lingerie company. They trade places with Derbyshire couple Mel and Sophie and their seven-month-old son Teddy, who live in a three-bedroom rented property in Derbyshire and exist on just £56 a week after bills for all their shopping and travel.
