Pennon Group, owner of South West Water, Bournemouth Water and Bristol Water, has raised its final dividend in line with its dividend policy– despite falling from a profit of £127.7 million in 2021/22 to a pretax loss of £8.5 million in 2022/23 in “an extraordinary year” which has tested its operational resilience.

The loss came on the back of a 4.1% rise in revenue to £825.0 million – up from £792.3 million in the previous year.
Commenting on the Group’s final results for the financial year ending March 31 2023, Susan Davy, CEO of Pennon Group, said:
“This has been an extraordinary year for Pennon in which extreme weather patterns have tested our operational resilience. At the same time, inflationary pressures have tested our financial resilience.
“We have been able to respond to both, with agility and pace, pivoting to focus on the things that matter right now, and tackling the biggest challenges head on. Whether it’s the use of storm overflows, water resilience, the cost of living crisis or climate change, we are investing more than ever
before.”
Susan Davy has previously announced she will forgo her bonus with the equivalent amount being invested into the Group’s WaterShare+ which directly benefits customers.
Pennon has attributed to the loss to inflationary pressures, including a 27% rise in operating costs to £517.2 million up from £408.4 million the year before. Underlying earnings before interest, tax, depreciation and amortisation fell by 20% to £307.8 million from £383.9 million the year before due to an increase in power costs. Adjusted earnings per share of 7.3 pence were down from 50.2 pence in 2021/22.
However, the Group is reporting a resilient, financial, and operational performance amid inflation pressure and a stronger focus on agile action. Performance highlights include:
