Water Industry Regulation Transformation

We have surpassed our target

Read our blog: 4000 inspections and counting: How we’re driving water industry performance(External link)


Aims of programme

The Water Industry Regulation Transformation Programme was launched in 2023. It sets out measures to transform the way we regulate the water industry to uncover non-compliance and drive better performance.

Increasing capacity and improving capability

The water industry is underperforming, and it needs to change. We know that people want and deserve more for their water environment. We are meeting this challenge head on. What do we want to achieve(External link)?

Enforcement activity

The Environment Agency is responsible for enforcing laws that protect the environment. We aim to use our enforcement powers efficiently and effectively to secure compliance, contributing to our work to create better places for people and wildlife, and to support sustainable development.



We take our responsibility to protect the environment very seriously.

We have significantly driven up monitoring of water companies with new flow monitors being installed on more than 2,000 wastewater treatment works and 100% of storm overflows now monitored. We are also increasing regulation surrounding operator self-monitoring tests. From January, water companies must reschedule samples if there is a no flow event.

Where significant pollution incidents occur, we investigate and take action, to stop the pollution as quickly as possible, and then to take enforcement action where necessary. We are carrying out our largest ever criminal investigation into potential widespread non-compliance by water companies, recruiting up to 500 additional staff, increasing compliance checks and quadrupling the number of water company inspections by March next year.

There are multiple pressures on inland and coastal waters; the water industry is one of them and a major contributor’ Reasons for not achieving good status (RNAG) and reasons for deterioration (RFD) record the source, activity and sector(External link) involved in causing an element to be at less than good status.

Every 5 years we review how we report on water company environmental performance(External link) and review the EPA. We deliberately tighten our metrics over time in response to investment made in industry assets and public expectation of better performance.
