The Department for Environment, Food & Rural Affairs has published a 16 June 2026 letter from Environment Secretary Emma Reynolds to Ofwat setting out concerns about proposals to recapitalise Thames Water.
The correspondence applies to England and concerns the London and Valley Water Consortium’s best and final offer, received on 6 March 2026. Reynolds wrote to Ofwat Chair Iain Coucher ahead of the regulator’s expected decision on the proposal.
The letter says the views are preliminary and do not constitute a direction from the government. It sets out concerns under duties linked to consumers, service delivery, company financing and statutory water obligations.
Government Concerns Over Thames Water Proposal
Emma Reynolds wrote to Ofwat after the regulator asked for preliminary views before reaching a decision on the London and Valley Water Consortium proposal. The letter notes that Ofwat is the independent regulator and that the government’s correspondence does not predetermine any future decision.
The proposal relates to Thames Water’s recapitalisation and includes requests connected to regulatory treatment, performance standards and future investment. Reynolds said Defra officials had been kept updated by Ofwat during the process.
- Proposal date: The London and Valley Water Consortium’s best and final offer was received on 6 March 2026.
- Decision stage: Ofwat was expected to reach a decision shortly after seeking preliminary views from the Environment Secretary.
- Legal duties: The letter refers to section 2 of the Water Industry Act 1991 and duties relating to consumers, services, financing and statutory obligations.
Consumer Costs And Regulatory Adjustments
The letter says the proposal expects consumers to fund an unprecedented level of regulatory adjustments. Reynolds said she was not yet convinced that the proposal demonstrated sufficient protection for consumers’ interests.
The measures described include prioritising asset health over capital improvements, switching off parts of the penalty regime and amending risk-sharing mechanisms. The letter says there will be some bill impacts in the current price review period and further rises in the next period as a direct result of the adjustments.
- Consumer protection: The Secretary of State raised concern that consumers could bear an undue cost from the requested adjustments.
- Penalty regime: The proposal includes changes described in the letter as switching off parts of the penalty arrangements.
- Risk sharing: The correspondence says changes to risk-sharing mechanisms form part of the proposal being considered.
Consumer Impact Areas
| Indicator | Recent Movement | Context |
|---|---|---|
| Bill impacts | Current and next price review periods | The letter says bill impacts are expected during this period and further rises in the next one. |
| Regulatory adjustments | Unprecedented level proposed | Reynolds said consumers were expected to fund a high level of requested regulatory changes. |
| Performance standards | Reduced standards requested | The letter says the proposal requests reduced performance standards affecting consumers and the environment. |
Environmental Standards And Investment Delays
The letter says the proposal suggests that a number of investments would be deferred, in some cases by up to a decade. Reynolds said this could delay environmental improvements, including wastewater treatment work linked to statutory requirements.
The correspondence also refers to projects important to drinking water safety and supply. Reynolds said she was concerned that the long-term resilience of water and wastewater systems may not be adequately protected.
Investment And Resilience Concerns
| Indicator | Recent Movement | Context |
|---|---|---|
| Investment deferral | Up to a decade in some cases | The letter says some investments under the proposal could be delayed for extended periods. |
| Wastewater treatment | Potential delays | Reynolds linked the concern to environmental improvements and statutory wastewater requirements. |
| Drinking water safety | Projects could be affected | The correspondence says some delayed projects are important to drinking water safety and supply. |
Ofwat Decision Process
The letter acknowledges the work carried out by Ofwat and the London and Valley Water Consortium in discussing and developing the proposal. Reynolds said her views were being shared for Ofwat’s consideration as it assessed the offer.
Reynolds said her comments were intended to inform Ofwat’s assessment rather than direct its decision. The regulator remains responsible for deciding whether the recapitalisation proposal meets legal requirements and protects consumers, services and long-term investment needs.
Stakeholder Comments
Ministerial Comments
Emma Reynolds, Environment Secretary of State said;
“I am not yet convinced that the Proposal demonstrates sufficient protection for consumers’ interests.”
“I am concerned that the long-term resilience of water and wastewater systems may not be adequately protected.”
The correspondence places Thames Water’s recapitalisation proposal within Ofwat’s regulatory decision process and the statutory duties applying to water services in England. The concerns focus on consumer costs, reduced performance standards, delayed investment and long-term system resilience. Ofwat remains responsible for its decision, while the Secretary of State’s letter records preliminary views for consideration.
