What our clients say about us
  • Office 21 provides quick, flexible and helpful IT support to our business. When Office 21 came onboard, we had seriously dated systems, the internet would go out daily, and employees had issues with emails. Since then, we have migrated to Google Apps, along with other cloud applications. The whole process was taken care of fully by Office 21. They also now provide our office phones, which frees up a lot of our time, now that we don’t have to talk to BT!

  • Guy and the team at Office 21 are FANTASTIC! They are quick to respond and always providing our ad-tech business with high quality IT support. In a short space of time Guy at Office 21 has helped navigate our company through a speedy office move, has implemented an IT management system, monitors that we are keeping compliant with GDPR, plus much more!! The support and advise we receive from Office 21 is always relevant and it's clear the team have an expert knowledge of IT. Most importantly though Guy at the team at Office 21 are approachable, willing to help and flexible with the needs of our business. I would definitely recommend their services to anybody!!
