Severn Trent Plc jumped 6.7% to 3,252.50 pence on Thursday, riding the surge in UK water stocks after United Utilities unveiled a larger investment plan and announced a share offer. United Utilities shot up 11%. Pennon added 5.6%.
Investors are back to probing just how far regulated UK water utilities can stretch for growth—and the price tag that comes with it. Demands to upgrade pipes, sewage networks, and reservoirs keep piling up, yet fury over both pollution and rising water bills hasn’t cooled.
United Utilities tossed investors a new valuation puzzle on this day. The company announced that its AMP8 capital investment plan—covering the 2025 to 2030 regulatory stretch—would jump to roughly 11.5 billion pounds, up from the earlier 9 billion pounds. To help cover that bump, it’s turning to an 800 million pound placing.
Revenue for the Warrington-based group hit 2.62 billion pounds in the year to March 31, a 22% jump. Pretax profit soared to 779 million pounds—more than twice last year’s figure. The company put forward a final dividend of 35.78 pence, a rise of 3.5%.
Jefferies’ Ahmed Farman flagged the upbeat growth and sturdier balance sheet as a plus for United Utilities — and for “the broader water sector.” That spillover effect pushed Severn Trent higher, despite Thursday’s actual update coming from a competitor. Proactiveinvestors UK
United Utilities CEO Louise Beardmore says the utility is making “real progress” tackling storm overflow spills and sewer flooding. Her remarks come as investors are looking beyond balance sheets—actual fixes on the ground are now the yardstick. Reuters
Severn Trent’s bet right now hinges on pulling off its investment-led strategy while not putting too much strain on the balance sheet. The water utility gave the green light to Ofwat’s PR24 final determination, locking in 14.9 billion pounds of spending for AMP8, thanks to the regulator’s approval.
The agreement sets the stage for a push to halve spills by 2030, trim leakage by an additional 16%, swap out around 1,400 km of mains, and pump money into 70 waste treatment plants. Regulatory Capital Value (RCV) — that’s the asset pile water companies use to earn their regulated returns. Severn Trent flagged that the outlined plan should deliver 45% real RCV growth through AMP8.
On the customer front, Severn Trent expects its 2025-30 plan to cover over 4.6 million people, with bills staying at the lower end for England. About one in six customers—around 700,000 households—should receive financial support, according to the company.
Severn Trent’s surge follows the appointment of a new chief executive. James Jesic, who’s spent years at the utility and is a chartered engineer, stepped in on Jan. 1. He replaced Liv Garfield, who left the board at the close of 2025.
Still, that read-through isn’t locked in. United Utilities’ £1.4 billion incremental investment proposal remains under Ofwat’s microscope; draft decisions are due August 15, with final word set for December 15. Any sign of harsher judgment, slimmer returns, or execution hiccups—those could take the heat out of the sector’s rally fast.
Severn Trent faces its next major check-in with investors on May 20, when it posts full-year results. The focus: signs the capital program is advancing, incentives are flowing, and dividend growth remains pegged to CPIH—Britain’s inflation gauge that factors in housing costs—without stirring up fresh political scrutiny.
