Eversheds has been appointed as primary legal adviser to Severn Trent.
The team, which will be led by Birmingham-based partner and litigation expert Ian Gray, will support Severn Trent on all commercial, real estate, employment and litigious matters.
The Eversheds team comprises experts across each legal discipline, drawing on the knowledge and skills of a number of Birmingham-based partners, including real estate expert Helen Annable, employment specialist Peter Norbury and utilities players Amrik Kandola, David Jones and Peter Scurlock.
The appointment has been made following a reorganisation of Severn Trent's in-house legal team, who were looking to partner with a firm that could deliver legal services in a timely, transparent and cost-effective manner.
Fiona Smith, general counsel of Severn Trent, said: "Eversheds impressed significantly as a progressive law firm that would invest time and energy in getting to know our business, and in helping us to get the very best advice at a reasonable and transparent cost.
"The arrangement with them is therefore anticipated to be a long-term association."
Mr Gray, head of litigation at Eversheds, said: "We have worked very hard to set our offering apart from other law firms and show in-house legal teams that we have the systems in place to work both efficiently and transparently.
