An additional £18.2 million penalty addresses improper dividend payments made in 2023 and 2024, despite the company’s poor performance.
Impact on customers
Ofwat has confirmed that the fines will be paid by Thames Water and its shareholders, not by customers.
However, the company’s financial struggles, including a £16 billion debt, have raised concerns about future service quality and potential bill increases.

Government response
Environment Secretary Steve Reed emphasised the government’s commitment to holding water companies accountable, noting that 81 criminal investigations have been launched into water companies.
What does this mean for you?
While customers won’t directly pay for these fines, the situation highlights the importance of regulatory oversight in ensuring water companies prioritise environmental responsibility and customer service.
But will customers end up footing the bill for price rises over the next years or will the water bosses get lower bonuses?
At least this year, their bonuses have been halted!
