Adrian Montague has resigned as chairman of the parent company to London’s embattled water supplier, Thames.
Montague was appointed in July 2023 and will remain as Thames Water’s chairman, but has stepped down from an array of positions linked to the firm, including at parent Kemble Water Holdings.
“This is a personal decision,” the company said.
“Sir Adrian believes the time is right solely to focus on fully supporting the board and executive team of Thames Water Utilities Ltd on delivering the refocused turnaround plan in order to better meet our customers’ needs.”
His resignation comes as questions remain over the supplier’s finances, with growing interest on its £18 billion debt pile having pushed Thames Water to the brink of collapse last summer.
Lenders had been told in September that there was “no certainty” that billions in rescue funding would be received.
This is due to such payments relying on the firm hitting regulatory targets - a sore topic for water firms which have faced scrutiny over the past year given the amount of sewage being dumped into Britain’s waterways.
