Stuart Hookins, property director at the Co-op, said: "The environmental credentials of the building have always been important to our Co-op.
"As part of our drive to make things ‘Fairer for the Planet’, we’re hoping a new co-resident can enjoy the same benefits we do and lower their carbon footprint.
"With the success of our hybrid working policy, a significant proportion of colleagues that previously spent four or five days in One Angel Square are now working flexibly, in support of their wellbeing and productivity.
"Now is the right time to look for others to share this amazing building."
Mark Cooke, associate director at Avison Young, added: "One Angel Square is one of Manchester’s most iconic office developments, with its central location and fantastic sustainability credentials, so it’s an excellent opportunity for companies seeking quality working environments with or without occupational fitout offering immediate occupation."
