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.

The Gold Standard; Colt tops Europe for Best Innovation in Customer Service

Because awesome customer experience is no longer a point of differentiation for businesses, it’s becoming the minimum. We understand our customers’ needs and expectations are always changing, and we are determined to not only meet these expectations, but to consistently go above and beyond. Read more...

"The overall evaluation of the service received is positive in two ways: first, due to the technical quality of the product in terms of its strength, consistency and security, and second, in terms of the advice and assistance received during both the pre- and post-sales stages."

Javier Bartolome
