Bill Hocking, chief executive of Galliford Try, said: “I am delighted to welcome the employees, clients and suppliers of MCS to Galliford Try.
“This acquisition is an excellent strategic fit with our enlarged water business, brings highly complementary capabilities into the Group and advances our Sustainable Growth Strategy.”
