Lesley from Penarth is a carer for her husband Dave and is at risk of losing her home due to a rent increase. She swaps houses, budgets and lives with wealthy Cardiff- based design entrepreneur Nicky Bright and her daughter Morgan, who find out that living on a tight budget can strain any relationship.

Families from opposite ends of the wealth and class divide swap homes, budgets and social status for seven days to discover how the other half live.

Dr Rashpal Singh and his wife Kiran own a successful cosmetics clinic and live with their four chidren in a large comfortable property in the suburbs of Middlesbrough. They swap lives for a week with Co Durham single mum Natalee, who survives on just £60 a week after bills and has taken out loans to try to start up her own nail business.

Devoted single Essex mum Ocean is desperate to build a better life for her eight-year-old daughter Oziana, but surviving on less than £60 a week is a huge struggle, and she dreams of leaving it all behind by opening a Caribbean food business. She swaps lives with multimillionaire Barrie and husband Scott, who have built a staggeringly successful business empire stretching from Beverley Hills to Chelmsford.

Iona Pennington inherited Muncaster Castle and estate in Cumbria, along with 1,700 acres, 40 tenanted properties, a hotel and two farms. In this programme, she swaps live with self-made Liverpool businesswoman Kate Stewart, who came from a working-class background. Iona begins to understand the joys of new money when she meets Kate's stylist for a personal clothes-shopping session, while Kate starts to see Iona's sense of duty to the financial near bottomless pit of Muncaster.
