To ask the Secretary of State for Environment, Food and Rural Affairs, whether her Department has made an assessment of the potential role of water efficiency measures in helping achieve the Government's net zero aims.
To ask the Secretary of State for Environment, Food and Rural Affairs, what discussions she has had with the Secretary of State for Energy Security and Net Zero on the potential merits of using water efficiency technologies to help reduce household carbon emissions.
We are working with the Department for Energy Security and Net Zero to maximise the synergies between the Government goals to reduce water demand and achieve net zero. We consulted on introducing a mandatory water efficiency label for water using products across all UK nations and assessed that such a label could save £125 million on water bills and £147 million on energy bills over 10 years. Hot water use is the second largest use of energy in a home after space heating. For example, installing a water-efficient showerhead could save a family of four about £30 on their combined energy and water bill each year.
