Company Performance and Price Reviews Cluster

The Company Performance and Price Reviews cluster is responsible for developing the approach to, and delivery of, future price reviews including the next price review in 2024 (PR24). In December we published ‘Creating tomorrow, together: our final methodology for PR24 Overview – Ofwat,’ which sets out how we will drive companies to deliver more for customers and the environment.  The methodology reflects our four key ambitions for the review:

  • focus on the long term,
  • deliver greater environmental and social value,
  • reflect a clearer understanding of customers and communities, and
  • drive improvements through efficiency and innovation.

Job description

The Team and The Role

The Cost assessment team is key to the delivery of PR24. We are an enthusiastic mix of economists and technical water sector specialists that are leading on the assessment of expenditure for the next price review. As part of this we work on the cross industry strategic planning frameworks such as drainage and wastewater management plans (DWMPs), water resources management plans (WRMPs) and the environmental programmes, including the Water Industry National Environment Programme (WINEP). We also lead work on a large number of policy areas such as how we can maximise the delivery of best value, how to ensure that companies focus on the long term and adapt to and anticipate change, how we can move towards net zero efficiently, and how best to reduce sewer flooding and improve drought and wider resilience. These are big issues for the water sector and beyond and our contributions are vital.

We are seeking Senior Associate, Water Specialist (engineer, scientist, or asset manager) to join our Cost assessment team. We are particularly interested in candidates that have a background and experience in one or more of the following areas:

*Water quality and security improvement activity and investment; or
*Mains renewal and asset health activity and investment.

The role will work across several key areas of PR24 cost assessment work which could include:

  • Supporting the development of approaches to assessing company water expenditure (water resources, treatment, and network distribution) for PR24 and how we benchmark costs and benefits including taking into account wider impacts, such as net zero, environmental benefits and climate change;
  • Assessing the quality and ambition of company’s business plans submitted for PR24;
  • Assessing elements of company business plans at the next price review. This includes the assessment of specific areas of water enhancement expenditure such as investment to address drought resilience, delivery of environmental improvements or to reduce water quality risks;
  • Applying of a range of data analysis and investment appraisal techniques including development of benchmarking models and undertaking detailed reviews of company proposals;
  • Engaging with water companies, other regulators and wider stakeholders throughout the PR24 process; and
  • Supporting the development of the approach for future price reviews.
