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. Following the Independent Water Commission’s Final Report and subsequent White Paper - 'New Vision for Water', the UK government has set out a bold new direction - one that brings together expertise from across the sector to deliver better outcomes for customers and the environment.
Ofwat is working in collaboration with the government and other regulators to help establish a new body for England, combining our strengths with those of the Drinking Water Inspectorate, the Environment Agency, and Natural England. We’re also continuing to engage with the Welsh Government to support future decisions 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.
The Role
The Assistant Accountant role is varied and involves providing essential support in financial operations and assisting in the effective management of financial resources.
