Alex and Steph head to Caerphilly to meet the Ingram family. HGV driver Liam and IT engineer Emma are proud parents to a 10-year-old and two sets of twins. Emma's mum Katrina also lives with the family but even with her help, jumping from one child to five in less than two years has had a massive impact on Liam and Emma's finances. To shock the family into making some big changes, Steph and Alex build a surprise pop-up-shop in the Ingram's house with some of their biggest spends, but how will they react when they know the cost of their big brand spending? To get their spending down, the family's budget-blowing belongings are banned and replaced with alternatives disguised in plain packaging so the Ingram's have no idea what's been swapped and what hasn't. But will the family like Alex and Steph's changes?
