Norse has been re-awarded a cleaning and security services contract at Northampton College.
The new three-year agreement, worth around £1.5 million, covers the three vocational teaching campuses that form the Ofsted-rated 'outstanding' college.
Norse has held the contract since 2010 and employs 50 cleaning and five security staff across the sites.
Bob York, head of facilities at the college, said; "Employees were transferred originally to Norse under TUPE in a seamless transition. We have enjoyed a very professional approach from Norse at all times."
Robert Trewick, operations director at Norse, said: "We have always prided ourselves on delivering high quality services with proven added value and flexibility, strengths which are clearly endorsed by this prestigious contract re-award by Northampton College."
Cleaning and security services are worth around £35 million to Norse across the country and provide employment for more than 3,000 staff.
