Who we work with

Our vision for the sector is ambitious and we cannot achieve it alone.

We work a wide range of stakeholders to ensure that we can drive companies to deliver a good quality and reliable service for customers, the environment and wider society. Below are some of the stakeholders we work.

Regulating the sector – who does what

We work alongside the UK and Welsh Governments and other regulators to oversee the work of the water sector. Find out more about who does what in our ‘Water sector overview‘.

We have agreements (‘Memorandums of understanding’) with organisations we work closely with. And framework for working with the Department for Environment, Food and Rural Affairs (Defra)

We also work closely with regulators in other sectors of the economy through the UK Regulators Network and Joint Regulators Group.
