* 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 Governments response to the Green Paper, Shaping the Future of Water Governance in Wales, and the Governments 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 youre 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 Senior Associate, Commercial Adviser role makes an important contribution to delivering Ofwats strategic objectives and regulatory commitments across the major water infrastructure portfolio.
You will join our growing Major Projects Team at Senior Associate level, working with the Commercial Lead across Ofwats £50bn pipeline of major water and wastewater infrastructure projects.
You will help develop and implement Ofwats commercial approach, including cost estimating, benchmarking, commercial strategy for procurement and tendering, contract strategy and commercial assurance. You will help develop and embed the frameworks, processes, methodologies and standards that provide a consistent, evidence-based approach to commercial decision-making and value for money across the full lifecycle of major water infrastructure projects.
You will lead, advise and supervise external suppliers delivering commercial assurance, setting clear requirements, providing technical direction and applying constructive challenge to ensure high-quality outputs. You will use assurance findings to strengthen Ofwats commercial frameworks and enable continuous, progressively deeper assurance as projects develop through their lifecycle and gates. You will also provide commercial analysis and advice to Ofwat project leads in preparing assurance reports and governance, supporting informed decision-making on Major Water Infrastructure Programme projects.
You will provide commercial advice across optioneering, business case development, procurement, tendering, contracting, construction and commissioning.
