Macquarie Group, a private equity firm, completed an investment of £550m in Southern Water, a private utility company. “We would like to thank Macquarie for its continued support, which will enable us to increase investment per household to more than £1.5k this regulatory period and manage the impact of cost inflation and higher funding costs on our business. Macquarie’s additional investment is a strong vote of confidence in our operational transformation. It will help us to deliver on our ambitions to customers and position Southern Water well for our upcoming regulatory determination," Lawrence Gosden, Southern Water CEO.
