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
We are looking for a Principal Capital Maintenance Specialist to join our base cost assessment team, which plays a pivotal part in shaping the next price review, setting capital maintenance expenditure allowances, and co-developing policy in areas such as asset health and improvements to the regulatory framework. This is an exciting opportunity for a water and wastewater technical specialist to serve as the technical lead within the base cost assessment team, responsible for developing and applying robust methodologies to evaluate capital maintenance investment proposals. You will ensure that cost assessments align with regulatory expectations and deliver value for customers and the environment.
As a Principal Capital Maintenance Specialist, you will:
- Lead technical assessment of capital maintenance investment proposals submitted through the PR24 cost change process for the 2025-30 period.
- Shape the approach for PR29, developing the methodology for setting capital maintenance allowances at PR29, drawing on lessons from PR24 and the recommendations from the Independent Water Commission (IWC) and subsequent White Paper.
- Contribute to policy development, including forward looking asset health metrics.
- Collaborate across Ofwat functions, working closely with principals, senior associates, and graduate associates to ensure robust, evidence-based recommendations.
- Engage with stakeholders across the sector, including water companies, other regulators, and government departments.
This role offers the chance to influence how billions of pounds of investment are assessed and funded, improving outcomes for customers and the environment. You’ll help implement key IWC and White Paper recommendations, including:
- Introducing a supervisory approach to setting expenditure allowances.
- Separating and ring-fencing opex and capital maintenance expenditure allowances.
- Developing forward-looking asset health metrics and strengthening requirements for companies to assess asset health.
