How could the Clean Water Bill reform affect Pennon Group?
Pennon Group may face new compliance costs due to water sector oversight reform The Clean Water Bill aims to overhaul the oversight of the privatised water sector by merging the functions of several existing regulators, including Ofwat, and creating a powerful new regulator. This change, supported by the Department for Environment Food and Rural Affairs, will give new powers to mayors to hold water companies accountable. As Pennon Group owns South West Water, these structural changes and increased regulatory demands could alter the company's operational requirements and financial risk profile.
