Thames Water had a costly and inefficient hiring process, with a cost per hire of over £4,000 and time to hire of over 26 weeks. They implemented a series of low-cost initiatives like an RPO, limiting temporary contracts to 12 weeks, revised attraction strategies, and social media recruiting. These changes led to dramatic improvements, with a cost per hire under £400, time to hire of 6 weeks, and positive candidate experience for 98% of applicants, all while spending less than the prior year's budget.
