Ofwat: ‘We have published our final methodology for the 2019 price review (PR19) for the water and wastewater monopoly service providers in England and Wales.

The methodology sets out:

• our expectations and requirements for companies preparing their business plans to meet the needs of their customers from 2020 to 2025 and beyond;
• how these expectations form the basis for how we assess company business plans;
• the approach that we will use if we need to intervene in those plans to ensure that companies deliver the step change required by customers; and
• how our assessment will flow through into companies’ price limits, service commitments and the wider incentive framework.
