On Thursday, Thames Water said it had started steps to raise its super-senior borrowing limit to £5.4 billion, up from £3 billion. The company says that upsizing would keep it running through autumn 2027 while a longer-term rescue is negotiated.
Creditors first extended the facilities as an emergency line in early 2025. With pressure mounting, Thames Water flagged in its latest annual report that, without a deal by October, it would need a further £2.4 billion. Lenders are now being asked to scale up support, with a vote on the company's requests set for Oct. 29.
Lenders have been shaping a recap bid that would see them assume control, but they still need the regulator's nod and buy-in from Prime Minister Andy Burnham's new government. The latest offer, not yet submitted, is anticipated to trim roughly 35% from the Class A debt and inject about £10 billion in fresh funding. Burnham has put the water sector at the center of a push for more public control and said at Labour's September conference he will look to remove limits on state ownership of major water companies in England and Wales, opening the door to public ownership. As a backup, his administration has been exploring placing Thames Water into special administration, a government-run insolvency process.
