Asked by: Natasha Irons (Labour - Croydon East)
Question to the Department for Environment, Food and Rural Affairs:
To ask the Secretary of State for Environment, Food and Rural Affairs, what recent assessment she has made of the effectiveness of local councils in exercising their statutory enforcement powers to protect local waterways from pollution; and whether her Department holds data on enforcement activity by local authorities.
Answered by Emma Hardy - Parliamentary Under-Secretary (Department for Environment, Food and Rural Affairs)
Local authorities do hold limited enforcement responsibilities, primarily through Environmental Health functions, for example, under the Environmental Permitting (England and Wales) Regulations 2010 in relation to certain industrial processes, and powers relating to flooding from ordinary watercourses. However, these are distinct from the regulation of water company discharges.
Enforcement against pollution from water companies is the responsibility of the Environment Agency, which issues discharge permits, monitors compliance, and takes civil or criminal enforcement action where offences occur. Defra sets the overall legislative and policy framework for this system, including recent reforms under the Water (Special Measures) Act 2025, which strengthens the ability of regulators to take faster and tougher action, including new criminal liability for company executives.

Question to the Department for Environment, Food and Rural Affairs:
To ask the Secretary of State for Environment, Food and Rural Affairs, what plans her Department has to analyse the forthcoming annual sewage discharge data to identify differences in company performance before and after the Water (Special Measures) Act 2025 came into force.
Answered by Emma Hardy - Parliamentary Under-Secretary (Department for Environment, Food and Rural Affairs)
Pollution incidents from the activities of the water industry are unacceptable and can have a devastating impact on our environment. The water industry must do more to reduce pollution and protect our rivers, lakes and seas.
As part of the Water (Special Measures) Act 2025, a new duty has been created on water and sewerage undertakers in England and Wales, to produce annual Pollution Incident Reduction Plans (PIRPs).
These statutory plans require water and sewerage undertakers to report on the number and severity of pollution incidents attributable to their networks over the last calendar year and propose actions to reduce that number in the next year.
The first statutory PIRP will be published by 1 April 2026.

Question to the Department for Environment, Food and Rural Affairs:
To ask the Secretary of State for Environment, Food and Rural Affairs, pursuant to the Answer of 8 September 2025 to Question 72871, on Water Charges, what cost-benefit analysis her Department carried out when choosing not to introduce a national social tariff for water bills in the policy paper entitled A new vision for water: white paper published on 20 January 2026.
Answered by Emma Hardy - Parliamentary Under-Secretary (Department for Environment, Food and Rural Affairs)
The Government is working with industry to keep support schemes under review to ensure that vulnerable customers are supported. We are working with water companies to ensure vulnerable customers across the country receive support. This includes improving the guidance for companies to design the best social tariffs for their customers.
We expect all water companies to put appropriate support in place for customers struggling to pay their bills and to proactively engage with their customers to ensure they know what support schemes are available and how to use them. Over the next five years, water companies will have more than doubled the number of customers that will receive help with their bills through social tariffs from 4% in 2025 to 9% in 2030. We expect companies to hold themselves accountable for their commitment to end water poverty by 2030 and will work with the sector to ensure appropriate measures are taken to this end.

Question to the Department for Energy Security & Net Zero:
To ask His Majesty's Government whether the new energy performance certificates methodology will take into account higher-rated water heaters and infrared heating.
Answered by Lord Whitehead - Minister of State (Department for Energy Security and Net Zero)
Technologies for which we have already obtained sufficient evidence – including heat batteries for water heating – will be supported at launch of HEM: EPC. Other technologies will be added over time via the new innovative product recognition process.
Government is working with manufacturers to ensure that infrared systems can be represented fully and accurately. To enable this, further work is required from industry to develop a robust, validated test method for measuring their operative temperature.

Question to the Department for Environment, Food and Rural Affairs:
To ask the Secretary of State for Environment, Food and Rural Affairs, whether she has made an assessment of the potential merits of improving a) research, b) monitoring and c) labelling of perfluoroalkyl and polyfluoroalkyl substances.
Answered by Emma Hardy - Parliamentary Under-Secretary (Department for Environment, Food and Rural Affairs)
The Government published a PFAS Plan on 3 February 2026, which sets out its approach towards protecting human health and the environment from risks posed by PFAS.
Research is being commissioned and coordinated across the Government, regulators, academia and industry to close key evidence-gaps on PFAS health, environmental impacts and innovation of alternatives.
Defra has funded the Environmental Agency to develop one of the most capable PFAS monitoring programmes globally. Using improved analytical methods and data from a range of sources, it covers water, wildlife, soil and industrial emissions.
A number of the most harmful PFAS already have a mandatory classification and labelling for carcinogenicity under the GB Classification, Labelling and Packaging regime.

Question to the Department for Environment, Food and Rural Affairs:
To ask the Secretary of State for Environment, Food and Rural Affairs, if she will publish the flood and safety risk assessments for the proposed SESRO reservoir.
Answered by Emma Hardy - Parliamentary Under-Secretary (Department for Environment, Food and Rural Affairs)
The Government is committed to delivering best value for customers through the water infrastructure programme, while supporting growth and ensuring a resilient water supply. The Government’s Water Delivery Taskforce is working across Government, regulators and water industry stakeholders to ensure this.
White Horse Reservoir is subject to ongoing assessment through the Regulators’ Alliance for Progressing Infrastructure Development (RAPID) gated process, which includes further investigations and assessments to inform a development consent application.
Through the development consent process consideration is given to flood and safety management and other regulatory requirements. This sits within the safety framework set out by the Reservoirs Act. All required assessments will be submitted by Thames Water to the Planning Inspectorate and the Secretary of State for consideration.
Asked by: Olly Glover (Liberal Democrat - Didcot and Wantage)
Question to the Department for Environment, Food and Rural Affairs:
To ask the Secretary of State for Environment, Food and Rural Affairs, whether her Department holds information related to an independent comparative assessment of the potential cost to the public pursue of Thames Water's White Horse reservoir proposal with (a) the creation of a smaller reservoir, (b) Severn-Trent Transfer, and (c) a combination of both options.
Answered by Emma Hardy - Parliamentary Under-Secretary (Department for Environment, Food and Rural Affairs)
Thames Water has selected the reservoir as part of its statutory Water Resources Management Plan. Water Resources South East has also conducted an options appraisal process, identifying the reservoir's necessity in its Regional Plan. The plans continue to be scrutinised by the water regulators.
