Iain Coucher was reappointed as Chair of the Water Services Regulation Authority (Ofwat) for a second term, according to a Department for Environment, Food & Rural Affairs and Ofwat announcement published on 6 October 2026. The term was reported as commencing on 1 October 2026 and continuing until the new integrated water regulator is established, and no later than 30 June 2029.

The department said Ofwat would remain fully operational and keep its existing legal powers during the transition to the new regulator, working closely with Defra and partner agencies. It said further details of the government's approach to the water industry would be set out in the 10-year plan for Britain, due later this year, and taken forward through a strengthened Water Bill.

Coucher has chaired Ofwat since 1 July 2022 and also chairs its Major Projects Committee and Nominations Committee. Ofwat is the economic regulator of the water and sewerage sectors in England and Wales.
