The enforcement of licence conditions is a matter for Ofwat as the independent economic regulator. To remedy its licence breach in losing its investment grade credit ratings in 2024, Ofwat has confirmed it accepted an enforcement undertaking from Thames Water in August 2024 (Ofwat confirms actions for Thames Water following investment credit rating downgrade - Ofwat). These commitments will remain in place until the company regains two investment grade credit ratings.
