Thames Water Fined £18m for Rule Breaches
Thames Water has been fined £18m by Ofwat for distributing dividends contrary to its licensing conditions, alongside broader regulatory breaches and repeated environmental incidents.

Thames Water Penalised for Breaching Regulatory Standards
Thames Water has come under heavy scrutiny following a significant penalty imposed by water regulator Ofwat. The company has been fined £18 million after it was found to have paid out dividends to shareholders in clear contravention of updated industry rules introduced to ensure responsible financial and environmental management.Sequence of Dividend Payments Triggers Investigation
In October 2023, Thames Water Utilities Holdings Limited (TWUL) paid £37.5 million in dividends to its holding company. This was followed by a further payment of £158.3 million in March 2024. Both distributions occurred despite:- Declining service levels affecting customers
- Sharp increases in consumer bills
- Widespread pollution incidents, including hundreds of sewage spills
- Sustainable dividend strategies
- Robust environmental performance
- Transparent stakeholder communications
- Review corporate governance frameworks against Ofwat's standards
- Adjust dividend policies to reflect service and environmental benchmarks
- Use recent enforcement actions as case studies for board training
- Monitor Ofwat announcements for further guidance
Ofwat determined that these payments breached the P30 Licence Condition, a requirement introduced in 2023. The condition aimed to ensure that dividend payments are only made when service delivery, environmental performance, profitability, and risk management meet strict criteria. The regulator’s investigation concluded that Thames Water failed to meet these benchmarks on multiple fronts.
Regulatory Context and the P30 Licence Condition
The P30 Licence Condition was established to strengthen accountability within the water sector. It mandates companies to prioritise customer service and environmental obligations before rewarding shareholders. Thames Water’s decision to pay dividends under worsening service levels and persistent pollution stood in direct conflict with the spirit and the letter of this regulation.Breakdown of Penalties and Issues

Dividend to holding company | Oct 2023 | £37.5 million | P30 Licence (service failures, pollution) |
Second dividend | Mar 2024 | £158.3 million | Ongoing breaches |

Broader Implications for the Sector
