Carillion will now look after Nationwide’s entire property portfolio including its 800 high street branches across the UK.
The three year deal starts this month with an option to extend it for a further two years.
The Virgin deal renews a current agreement and extends Carillion’s partnership with Virgin Media to at least mid-2013 and potentially to mid-2015.
Carillion will continue to deliver hard and soft facilities management services for Virgin Media’s UK national estate, including their headquarters campus in Hook.
John McDonough, Carillion Group Chief Executive, said: “We are delighted to have secured these new contracts with the Nationwide Building Society and Virgin Media.
“This reflects the strong relationship we have built with these customers, for whom we already provide extensive facilities management services.
“We look forward to strengthening these long-term partnerships under the new contracts.”
