Ofwat has launched a consultation on its proposed framework for assessing water companies’ progress against PR24 delivery plans, which underpin the £104 billion investment programme for the water sector in England and Wales. Ofwat said the framework is intended to improve transparency, identify delivery risks at an early stage, and strengthen oversight of how companies deliver funded improvements for customers and the environment. It explained that PR24 represents the largest investment programme in the sector for more than 30 years, driven largely by statutory environmental, water quality, resilience and supply-demand requirements, and noted that the scale of investment creates risks linked to supply chain capacity, labour shortages, and competition from other infrastructure sectors. The proposed assessment approach would evaluate whether companies are forecast to meet Price Control Deliverable (PCD) targets by 2030 and assess confidence in those forecasts through evidence on mobilisation, programme planning, expenditure management, data quality, risk management, and independent assurance. Ofwat said it would use both quantitative and qualitative evidence, including interim milestones and engagement with companies and suppliers, to form a company-level view of delivery progress. It also stated that much of the delivery profile is expected to be concentrated in the later years of the 2025–30 period, particularly for large capital schemes such as storm overflows and phosphorus removal, while activities such as mains renewals and smart metering are expected to be delivered more evenly across the period. Ofwat said it may intervene where delivery concerns arise through enhanced monitoring, challenge letters, improvement plans, or further supervisory action. The consultation closes on 18 June 2026.
