Expected to be worth approximately £350 million, the contract has the potential to be extended for a further three years and builds on an existing partnership of nearly nine years during which Carillion has been providing facilities management services for Nationwide.

Under the new contract, Carillion will provide a wide range of hard and soft facilities management and workplace services for Nationwide’s Headquarters in Swindon, its 15 corporate offices, critical data centres and 700 retail branches throughout the UK.

Specifically aligned to Nationwide’s sustainability strategy, the services will include energy management, risk assurance, asset maintenance, capital works, front-of-house, security, grounds maintenance, mailroom management, porterage and cleaning.

Carillion said its customer experience and ability to develop operational and technological enhancements were key to its success in winning the contract.

Carillion group chief executive, Richard Howson, said: “We are delighted to have renewed our contract with Nationwide Building Society. This demonstrates the success of our long-term partnership with Nationwide and our focus on differentiating Carillion by working collaboratively with customers to deliver an outstanding customer experience, using our expertise in whole-life property management and services.

“Our strong emphasis on delivering sustainable services is also a key differentiator, as both Nationwide and Carillion are focused on responsible business practice that maximises the benefits our operations can have on the communities in which we operate.”
