A GOV.UK announcement confirms that Iain Coucher has been reappointed as Chair of the Water Services Regulation Authority, better known as Ofwat, for a second term beginning on 1 October 2026. The government states that the appointment will last until the new integrated water regulator is established and, in any event, no later than 30 June 2029. The timing is significant because it gives the water regulator a defined leadership arrangement while ministers prepare a wider restructuring of sector oversight. Rather than creating a gap between the present regime and the next one, the reappointment is presented as a continuity measure during transition.
The announcement places the decision within a broader reform programme for the water sector. In the government's account, that programme is built around tougher regulation, stronger enforcement, greater public control and sharper accountability, with the stated aim of securing cleaner waters, fairer bills and better outcomes for customers and the environment. A fuller statement of policy is still to come. Ministers say further detail will appear in the 10-year plan for Britain, due later in 2026, and that this will support reform through a strengthened Water Bill. On that basis, the chair reappointment is less a routine board matter and more a holding arrangement while legislation is prepared.
For immediate regulatory purposes, the GOV.UK text is explicit that Ofwat remains fully operational throughout the transition. It will keep its existing legal powers and continue working with the Department for Environment, Food and Rural Affairs and partner agencies until the new integrated regulator is in place. That assurance matters for companies, investors and consumer bodies. It indicates that price setting, monitoring, enforcement activity and company oversight continue under the present statutory framework unless and until Parliament changes it. The government is signalling reform, but not a pause in regulation.
Ofwat's present role also remains unchanged. The Water Services Regulation Authority is a non-ministerial government department and the economic regulator for the water and sewerage sectors in England and Wales. Its formal task, as set out in the announcement, is to ensure that regulated companies provide good-quality and efficient services at a fair price. In practical terms, that means the current regulator stays responsible for day-to-day economic oversight during the handover period. The reference to an integrated regulator points to future institutional redesign, but the existing authority continues to exercise its statutory duties until any replacement structure is formally established.
The biography published alongside the announcement presents Coucher as a chair with experience across regulated infrastructure and public bodies. He first became Chair of Ofwat on 1 July 2022 and also leads the regulator's Major Projects Committee and Nominations Committee. Outside Ofwat, the GOV.UK notice says he is a senior adviser at HIG Capital, a trustee of the British Trust for Ornithology and a non-executive director of Charge UK. Previous posts include chief executive roles at the Atomic Weapons Establishment and Network Rail, as well as non-executive positions at Cadent Gas plc and the Rail Safety and Standards Board.
The practical effect of the announcement is to keep the current regulatory structure stable while ministers prepare a stronger statutory model for the sector. By fixing the chairmanship from 1 October 2026 and tying the term to the establishment of the integrated regulator, with an outer limit of 30 June 2029, the government has linked the appointment directly to its reform timetable. The next policy markers are now clear. Stakeholders will need to watch for the promised 10-year plan for Britain and the contents of the strengthened Water Bill, since those documents are expected to explain how greater public control, tougher enforcement and the new regulatory model will operate in legal and administrative terms.
