Customer surveys

Public Rulings and Technical Standards (together referred to as the Public Statements Service) run a three yearly customer survey to identify levels of customer satisfaction and to invite comments on ways in which they can improve products and services.

We are currently reviewing the results of our 2024 survey and will post a report in early 2025.
