Ofwat has decided not to fine Severn Trent Water despite finding serious and unacceptable breaches in the company's handling of wastewater and sewage networks. The regulator acknowledged that the FTSE 100 company had proactively identified problems and began addressing them before the enforcement case was opened in July 2024.
Background of the Investigation
Ofwat has been conducting an industry-wide investigation into how water companies manage wastewater and sewage networks. Severn Trent is the eighth case completed in this investigation, which has resulted in fines and enforcement packages exceeding £300 million. In all other seven cases, Ofwat issued fines ranging from £11 million to £104 million, with the largest penalty imposed on Thames Water in May last year for wastewater failures.
Severn Trent's Proactive Measures
Unlike the previous seven cases, Severn Trent identified problems in its network and began fixing them before the case was opened. The company now has the proper systems and processes in place and has invested £98 million of shareholder funds into improving its infrastructure. This investment has led to a 41% reduction in spills from each storm overflow in 2025 compared with 2024, despite experiencing heavier rainfall than some other regions.
Shares in Severn Trent fell nearly 2% on Wednesday following the announcement.
Regulator's Comments
Lynn Parker, Ofwat's senior director for enforcement, stated: “Our investigation found serious and unacceptable breaches by Severn Trent Water – that is not in question and the company accepts it. But their response to those failures sets a standard we expect from all companies: identifying the problem, proactively investing to fix it and cooperating openly with the regulator. The 41% reduction in spills we are now seeing is what genuine accountability looks like in practice.”
She added: “We will always act where companies fail their customers and the environment. But we will also be clear, publicly, when a company does the right thing.”
Company Response
James Jesic, the chief executive of Severn Trent, said: “We accept Ofwat’s findings relating to issues that we proactively identified, and began addressing these before the enforcement case was opened. Our investment programme in spills reduction continues across our region at pace with the strength of our whole organisation and supply chain behind it. We still have work to do and remain absolutely focused on delivering further improvements for our customers and the environment.”
Ofwat is still investigating United Utilities and Hafren Dyfrdwy, a Welsh provider owned by Severn Trent, as part of its sector-wide investigation.
CEO Pay Controversy
Separately, The Guardian reported that Severn Trent had doubled the size of a long-term reward scheme for Jesic to as much as £3.1 million, and he could receive significantly more than his predecessor. The long-term incentive plan increased from 200% of Jesic’s base salary to 400%, potentially allowing him to earn up to £4.8 million in a single year including salary, bonus, LTIP, and benefits. Severn Trent defended the policy, stating it follows Ofwat's rules and is funded by shareholders, not customer bills.
