Independent Water Commission: review of the water sector
The Independent Water Commission’s final report sets out recommendations for reform to improve the water sector regulatory system in England and Wales.
Government Response
Government issued an initial response to Sir Jon Cunliffe's Independent Water Commission on 21 July 2025 (Environment Secretary Steve Reed speech, plus Written Ministerial Statement HCWS865). It announces abolition of Ofwat and a single water regulator merging Ofwat, EA, Natural England and DWI water functions. A full response and White Paper (later delayed to 2026) and a water reform bill are to follow.
Recommendations
Recommendation 1
The UK and Welsh government should each bring forward a new, long-term, cross-sectoral, and systems-focused National Water Strategy for England and Wales respectively.
Recommendation 2
The UK and Welsh governments should revise the legal framework for the Strategic Policy Statement and replace this with a new Ministerial Statement of Water Industry Priorities (MSWIP), directing all water industry regulatory and systems planner functions.
Recommendation 3
A comprehensive systems planning framework should be introduced for England and Wales, with responsibility for integrated and holistic water system planning. In England, the systems planners should be regional – or 'regional water authorities'. In Wales, the systems planner should be a national authority.
Recommendation 4
The 5-year Price Review cycle should be retained, in England and Wales, for setting water bills and company revenues over a 5-year period but water industry investment planning should be conducted on a 5/10/25 year basis with the greater certainty and granularity for the first 5 years, more indicative plans for the following 5 years and higher level indication for the longer term.
Recommendation 5
Water industry planning should be rationalised down from 9 plans into 2 core planning frameworks – 'Water Environment' and 'Water Supply.' This applies to England and Wales.
Recommendation 6
The national coordinator of the systems planner in England, and the national systems planner in Wales, should take on responsibility for ensuring consistency in scenarios, assumptions, and metrics for water industry planning across the new planning framework.
Recommendation 7
The systems planner, with the support of the economic regulator, should require, support, and scrutinise a strengthened approach to option development and cost-benefit analysis across water industry planning frameworks. This applies to England and Wales.
Recommendation 8
The UK and Welsh governments should review the current water legislative framework and amend it accordingly.
Recommendation 9
The UK and Welsh governments should update and reform the UWWTR 1994 to deliver better outcomes and a more sustainable approach to drainage and wastewater management. This should involve reporting on whether an Extended Producer Responsibility scheme is needed for the water sector to fund necessary improvements.
Recommendation 10
Government should consider legislative changes to drive a more coherent approach to 'pre-pipe' solutions to stop pollutants and rainwater entering the system.
Recommendation 11
The UK and Welsh governments should consult on reforms to the WFD Regulations, including broadening the scope to include public health outcomes.
Recommendation 12
To facilitate a robust assessment of how public health can be effectively incorporated into a new water framework, the UK and Welsh governments should establish taskforces led by the Chief Medical Officers of England and Wales to review the incorporation of public health better into the legislative framework for water.
Recommendation 13
Future water monitoring programs should be reviewed and adequately resourced, to accurately reflect the state of the environment.
Recommendation 14
In England, the review of the legislative framework should take forward the concept of 'constrained discretion' for the regulator. This should also apply to the water systems planners, should they sit in an independent body.
Recommendation 15
In Wales, a strengthened constrained discretion framework should build on the discretion already enabled by the sustainable development principle within the Well-being of Future Generations Act.
Recommendation 16
The UK Government should establish a new integrated regulator in England. This should combine the functions of Ofwat, DWI, and water functions from the Environment Agency and Natural England.
Recommendation 17
The Welsh Government should establish a new economic regulatory function in Wales that can align directly with the Welsh Government's strategic direction and guidance. The Commission's view is that the better course, subject to consultation, would be to embed this into NRW alongside the wider regulatory functions for water in Wales, though a small freestanding body, as in Scotland, might also be considered.
Recommendation 18
The regulator should adopt a more 'supervisory approach' to regulating individual companies. This applies to England and Wales.
Recommendation 19
The regulator should ensure funding is directed appropriately to renew assets by clearly defining and ring-fencing base capital expenditure (capital maintenance), base operational expenditure and enhancement capital expenditure allowances. This applies to England and Wales.
Recommendation 20
Following the establishment of a new methodology for assessing asset condition and expected life, the regulator should consider the merits of linking RCV run-off more closely to the economic depreciation of assets. This applies to England and Wales.
Recommendation 21
The regulator should withdraw the quality and ambition assessment (QAA). This applies to England and Wales.
Recommendation 22
The regulator should review the performance incentives framework, to rationalise the overall number of PCs and make their corresponding ODI rewards, penalties and returns at risk, clear. This applies to England and Wales.
Recommendation 23
UK Government should consider providing the CMA with responsibility to set a common WACC methodology for all UK regulated sectors. This includes the water sector in England and Wales.

Recommendation 29
The EA should accelerate their efforts to bring resolutions to long-running enforcement cases in consideration of the public interest of delivering justice for any historic offences.
Recommendation 30
The regulator should significantly accelerate the implementation of digital programmes to support intelligence-led and transparent enforcement and compliance activities.

Recommendation 37
The UK and Welsh government should accelerate efforts to reduce household water consumption by introducing compulsory smart metering for a wider range of circumstances.
Recommendation 38
Tariff structures should be changed to incentivise water efficiency. This could involve removing falling block tariffs for non-household consumption.
Recommendation 39
Standards should be issued for the roll-out of smart meters in the non-household market in England and Wales.
Recommendation 40
The UK and Welsh governments should work with their regulators to develop a new policy and regulatory framework to drive the adoption of water re-use infrastructure in the household and non-household markets.

Recommendation 53
UK Government should use the opportunity of this review and its decisions on the implementation of the Commission's recommendations to reset its approach to strategic communications regarding the water industry. Its object should be to set justifiable criticism within the context of reform and to show support for the industry as performance improves. The Government should also set the sector's environmental performance in the broader context of the contributions of other sectors to achieving environmental objectives, especially where remedial action for past failures is underway.

Recommendation 61
The government and regulator in England and Wales should explore short-term measures to improve the functioning of the BRM.
Recommendation 62
The framework for regulating NAV applications in England should be made more proportionate to support housing growth. The Commission recognises that given different views on the benefits of NAVs, the Welsh Government may decide not to pursue these reforms these reforms.
Recommendation 63
The Commission sees a strong case for dropping the requirement for NAVs to produce WRMPs and DWMPs given the view of the EA and for changes to the requirements upon them in relation to drinking water testing.
Recommendation 64
The Commission believes the UK government should monitor NAV market size and risk of fragmentation.
Recommendation 65
The regulator in England should continue the essential steps that Ofwat is taking to address issues with DPC and SIPR. A full evaluation of both schemes should be undertaken in 5 years when a broader evidence base has been accumulated. The Commission recognises that given different views on the benefits of DPC and SIPR, the Welsh Government may decide not to pursue these reforms.
