To ask the Secretary of State for Environment, Food and Rural Affairs, whether any storm overflow discharges took place in Chipping Barnet constituency in 2023.

Defra and the Environment Agency have instructed water companies to introduce Event Duration Monitors (EDMs), which provide them with much more information about where and when storm overflow discharges have occurred. Water companies submit annual returns of their EDM data, which are publicly available. The annual returns for 2023 are not yet available. At the end of 2023, the Government target of having all storm overflows in England monitored was met, so the EDM data for all sites should soon be available.
