This paper presents an assessment of the benefits that we generate as the economic regulator of the water sector. We have focused on areas of our work where we can more easily quantify the benefits we generate. The analysis does not, therefore, purport to cover all our activities as a regulator. Even within the areas we consider, we can only quantify some of the benefits of our work. Nevertheless, we consider this assessment to be a useful illustration of the nature and scale of our impact and the benefits for customers, society and the environment arising from our regulatory activities.
