Customer experience; continuing to lead with our NPS

Our score reflects the time and effort we put into our global CX programmes, the attitude of our leadership and the focus of every colleague on our customers. We put the customer at the heart of everything we do, and I’m thrilled that both our EU and Asia NPS have demonstrated that over the last couple of years. This compliments and goes alongside the work we’re doing on our Net Easy Score (NES), which looks at how easy it is to do business with us, across a range of transactions and touchpoints.
