Lucy meets a couple after her own heart: Neil and Kerry from Bristol are the king and queen of bargain hunters when it comes to getting great deals on everything from kitchen appliances to end-of-line loos. They even save a fortune on builders by doing it themselves. The couple have left the kitchen and utility rooms till last; can Lucy and Harry help them squeeze every penny to create a quirky modern kitchen with a monumental island? One thing's for sure: the colour yellow is going to be key. Kerry wants yellow walls, a yellow banquette seat and even yellow grouting between the tiles. Will Lucy and Harry be able to help them balance the bright colour whilst balancing the books?
