Ofwat Announces Final Determinations 2025-30

This morning, Ofwat announced the Final Determinations for 2025-30 for England and Wales.

The key headlines are:

• Ofwat has approved a £104 billion upgrade to accelerate delivery of cleaner rivers and seas and secure long-term drinking water supplies for customers

• Investment set to quadruple – nearly 90% of this will go to meet new requirements set out by the Environment Agency, Natural Resources Wales and the Drinking Water Inspectorate

• Almost £12 billion allocated to cutting spills from storm overflows by 45% by 2030, from 2021 levels – more than £6.5 million investment per day over the PR24 period

• £2 billion development funding to kick start £50 billion investment for the biggest programme of water supply projects in decades

• In total, 30 major infrastructure projects will build greater resilience to drought by providing enough water to meet the daily needs of around a third of England and Wales' population

• Bills set to increase by an average of £31 each year over the next five years; a doubling of support for customers in need of a helping hand

• Claw back mechanism to ensure money not spent on investment by companies is returned to customers through lower bills
