Facilities services provider Arcus has extended its contract with Sainsbury's, securing a 10-year renewal with the retailer.
Arcus won the initial contract in 2009, and saw the contract extended in 2011.
Under the terms of the new deal, Arcus is to continue its provision of FM services across the Sainsbury's UK estate, including all supermarkets, convenience stores, petrol stations and depots.
Its responsibilities also include refrigeration remote monitoring, energy management and compliance management, as well as M&E maintenance, building fabric and lighting services.
Chris Green, chief executive at Arcus, said: "A joint venture model is undoubtedly the most challenging and demanding. However, if executed well with high commitment on both sides then it has the potential to be the most rewarding."
