Multimillionaires Steve and Gemma, their daughter Sadie and Steve's granddaughter Arianna swap lives for a week with Ben, his partner Demi and their daughter Lillie. Steve and Gemma live in a newly renovated five-bedroom house in the seaside town of Redcar and own nearly 80 properties worth over £6 million, while Ben and Demi live in a rented two-bedroom, terraced house in Co Durham and rely on Ben's zero-hour contract work as a roofer.

The Fox family from Bradford swap houses, budgets and lives with the James family from the Home Counties. Jamie lives in a rented house with her husband Lee and three children, but with few opportunities, she can only work part-time in a local café and Lee has just qualified as a lorry driver. Jessen James has made millions in business and now trains and mentors businesspeople in sales, marketing and mindset. During the week Jessen and his family have to live off a budget just three per cent the size of their normal disposable income.
