Join Ofwat's Chief Economists Team as a Principal Economists

Office Location: London (E14 4HD) or Birmingham (B5 4UA) with hybrid working

About Us

We are Ofwat, the Water Services Regulation Authority, a non-ministerial government department responsible for regulating the water sector in England and Wales.

The water sector is entering a new chapter. The government has set out a bold new direction, bringing together expertise from across the sector to deliver better outcomes for customers and the environment. We are collaborating with fellow regulators to respond to recommendations in The Independent Water Commission Report, the Welsh Government's response to the Green Paper, Shaping the Future of Water Governance in Wales, and the Government's White Paper, A new vision for water.

Ofwat is working with the government and other regulators to help create a new body for England, bringing together our strengths with those of the Drinking Water Inspectorate, the Environment Agency and Natural England. We are also continuing to work with the Welsh Government to support decisions on the future arrangements for Wales.

While these changes take shape, our mission remains the same: to hold water companies to account, drive performance, and ensure the sector delivers real value for customers, communities, and the environment. If you're passionate about making a difference, this is a unique moment to join us and help shape the future of water, and together we can continue to make a positive impact.
