Churchill Cleaning has extended its cleaning contract with the City of Norwich School.
Churchill has been providing cleaning at the school for nine years, making it one of the company's longest-established partnerships.
According to a statement released last week, Churchill retained the contract by "remaining flexible to the school's changing requirements". The school was also impressed by the cleaning firm's value for money and "strong management structure".
As part of the retender, the firm carried out a contract review that covered all service areas, from energy use to rationalising cleaning shifts.
Chris Harding, Churchill's regional director, said: "I am grateful to the staff and local manager for the enthusiasm and team effort adopted to ensure Churchill were allowed the opportunity to build on [this] fantastic relationship."
He added that the team is looking for further opportunities to expand its service delivery with the school.
