She will be responsible for leading the delivery and coordination of the company’s transformation programme as it continues with its growth strategy.
McLay will join the company on 3 June and will report directly to chief executive Jo Dow.
Her most recent position was head of management operations at Tesco Bank, where she was part of the team that oversaw the transition from RBS to Tesco, including the IT delivery of core infrastructure and software to support the formation of the bank. Prior to this, she served as head of IT at HBOS, where she was responsible for end to end IT service.
Commenting on her new appointment, McLay said: “I am really excited to be joining Business Stream at a time of significant growth. In my new role as director of business transformation I am looking forward to working in partnership with the executive team to enable the business to maintain excellent customer service levels and to achieve its strategic goals”.
Jo Dow, chief executive of Business Stream, added: “I am delighted that Margaret will be joining the company. It’s an exciting time for the business as we look to expand our market share and deliver a market leading level of service to our customers in Scotland and England. This latest appointment will strengthen our leadership team and help us drive forward our ambitious plans for the future”.
In January, Business Stream announced it had bought the customer bases of the Yorkshire Water Business Services and Three Sixty, both part of the Kelda Group. The deal is expected to take effect this summer, subject to regulatory approvals.
Last month, the company confirmed it would not be entering the race for Aqualflow’s customers after the latter supplier entered liquidation.
Business Stream told Utility Week that its “key priority” is to ensure the smooth transition of the non-domestic customers from Kelda Group.
This year, the company has won water supply contracts with Cancer Research UK and Lloyds Banking Group.
