Our complaints performance

We’re on a mission to make energy better, and we take pride in offering great customer service. We also know there’s always room to do more. That’s why we regularly review the feedback we get from customers about how we’re doing – and where we can improve.

Keeping you updated

We’ve committed to updating this page so that we’re transparent about how we can do better for our customers. We can’t promise to always get it right. But we can promise that we’ll learn and improve.
