 After meeting at a hen party the sister-in-law of Sarah Delafield-Cook, a talent hunter at Talkback Thames, Beeny was asked to undertake a screen test to front a new programme series about property development, which was to be fronted by a property expert.Taking the advice of her stepmother, the successful format "Property Ladder" has led to various spin-off series, including "Streets Ahead", "Britain's Best Homes" and "Property Snakes and Ladders".In 2006, Sarah presented another Channel 4 programme, "One Year to Pay Off Your Mortgage".
