Energy giant GSH has received an extension of its energy and technical services contract with the National Australia Group (NAG). The contract is worth over £100 million and will see contract services provided until 2020.

GSH will continue to provide services to such GSH brand as Yorkshire Bank and Clydesdale Bank, including 450 High Street branches.

Dan Moore, head of property at NAG, commented: “Over the past five years we have worked closely with GSH and they have played a vital role in helping us to achieve our targets. This, and their excellent service delivery record on M&E, are the main reasons that we are happy to commit for the long term to 2020.”
