“Continuity and stability” was the message from ministers as Julie Hill was confirmed on 2 February as interim chair of the Office for Environmental Protection (OEP) in a joint appointment with Northern Ireland. Hill takes over immediately for a four‑month stint to 31 May 2026 while the permanent recruitment concludes, according to Defra and the OEP. (gov.uk)

Set up under the Environment Act 2021, the OEP’s job is to hold governments and public bodies to account on environmental law across England and Northern Ireland, including some reserved matters UK‑wide. It scrutinises Environmental Improvement Plans, advises on changes to law, and can investigate and enforce where public authorities fall short. (theoep.org.uk)

For readers across the North, the timing matters. In December 2024 the watchdog found that Defra, the Environment Agency and Ofwat had failed to comply with environmental law in their oversight of combined sewer overflows, issuing decision notices that set out fixes and warning that court action could follow if progress stalled. (theoep.org.uk)

By July 2025 the OEP said it would close that investigation after securing reforms: Defra published updated storm overflow guidance; Ofwat tightened enforcement and announced decisions involving Yorkshire and Northumbrian Water; and the Environment Agency began a permit modernisation programme. The EA plans to review 8,400 CSO permits as part of 14,250 storm overflow permits, with implementation beginning in 2026. (theoep.org.uk)

Communities in the North West, North East and Yorkshire have lived with sewage discharge headlines for years. With Hill now in post, the OEP’s pressure on regulators and ministers remains - setting clear expectations for the water companies operating on our patch. The legal levers sit with public authorities, but the watchdog’s work has already shifted how they act. (theoep.org.uk)

The joint UK–NI appointment reflects the OEP’s Northern Ireland role. In November 2025 it opened an investigation into how DfI, DAERA and the Utility Regulator oversee sewage discharges into Belfast Lough. “Nature is under unsustainable pressure in Northern Ireland,” said OEP chief executive Natalie Prosser, as the inquiry got underway.

The wider picture in Northern Ireland is sobering. An OEP report in April 2025 found the share of monitored features on protected sites in favourable condition fell from 61.7% in 2008 to 51.5% in 2024 - a drop that underscores the need for steady leadership and delivery. (theoep.org.uk)

Environment Secretary Emma Reynolds thanked outgoing chair Dame Glenys Stacey for building the watchdog and said Hill’s experience “will ensure continuity and stability as we complete the process to appoint a permanent Chair.” The appointment was made under the Governance Code on Public Appointments.

Hill is well known in environmental policy circles: President of the Institution of Environmental Sciences and chair of the Food Standards Agency’s Advisory Committee for Social Science, with previous leadership at WRAP and board roles at the Environment Agency and the Eden Project. She also authored The Secret Life of Stuff. (the-ies.org)

What to watch for Northern readers: the 2026 rollout of modernised CSO permits and the outcome of the Belfast Lough case. For councils, developers and utilities across the North, the signal is simple - scrutiny won’t pause, and compliance expectations remain high while the OEP finalises its permanent leadership.
