Question to the Department for Environment, Food and Rural Affairs:

To ask the Secretary of State for Environment, Food and Rural Affairs, what estimate he has made of the amount of water lost due to leaking toilets in the UK; and if he will take steps to help reduce this.

Waterwise, the lead environmental non-governmental organisation for water efficiency, estimates to 8% of toilets are leaking around 400 litres a day each.

The Government is committed to reducing leakage by 50% by 2050 as part of our legally binding target to reduce water use per person by 20% by 2038. This includes taking steps to reduce water wastage from toilets. Our recent update to our government response on a Call for Evidence on leaking toilets, conducted in 2022 outlined we are reviewing initial discussions with stakeholders as part of a ‘leaky loos taskforce’ to understand the steps needed to reduce toilet leakage.
