Rich House, Poor House

In a brilliant episode that shines a stark spotlight on Britain's massive wealth divide, multi-millionaire plumbing entrepreneurs Sam and Scott Mullins swap lives with Lee and Laura, another couple in the trades who live a very different life.

Scott made his fortune helping dad Charlie grow Pimlico Plumbers into a £150 million company, which they sold in 2021. Their London pad is a £12 million Westminster penthouse with two private lifts that open straight into the main hallway. Oh, and there's also a £5 million Marbella villa, but things aren't as gilt-edged as they look. Last year, workaholic Scott had a near-fatal health scare. Blocked arteries were diagnosed, but Sam thinks it's down to stress, and her big hope for the swap week is that Scott will learn to slow down.

Plasterer Lee and gardener Laura live across London in their two-bed, top-floor Northolt flat with their teenage son and twins, Sadie and Katie. They share one bathroom, but the sink tap doesn't work, and the two bedrooms mean Mum and Dad often end up on the sofa.

The lack of space and financial struggles puts a huge strain on Lee and Laura's relationship. A big problem is that Lee lacks the confidence to take a driving test, which stops him growing his business. The couple have big hopes for the swap, that it will solve their relationship problems and build Lee's confidence. But when Laura learns female plumbers can earn £150k a year at Scott's company, their story has a surprise twist.

A single mum from Essex and her daughter swap homes with a millionaire entrepreneur who has made a fortune on Spain's Costa. Becky lives in the village of Hockley with her nine-year-old daughter Aimee, earning just above the minimum wage working as a trainee teacher, while home is a cramped terraced house. For one week Becky, Aimee and Nanny Bev travel to Spain to swap lives with Adam, his girlfriend Ebbe and his teenage son Jamie. Thirty-three-year-old entrepreneur Adam is another Essex native, but left Romford 15 years ago to set up as an estate agent in Alicante. His Spanish villa is on an exclusive golf course with a swimming pool and amazing views. Will Becky be tempted by a new life in the Spanish sun? Meanwhile, Adam teaches Jamie the real value of money by a week living on the breadline in budget Britain.
