Meet the most helpful IT team in town

When you’re looking for a long-term IT partner, why not choose one that does more than just solve problems? We work with you to improve your IT systems in the long run.

    • Filling in knowledge gaps. When your staff are struggling because they don’t know how to use something, our team takes the time to teach them.
    • Tackling repeated issues. If multiple members of your team report the same problem, we look at ways to adapt the system to their needs.
    • Proactive maintenance. We carry out proactive monitoring of all your systems to detect any early warning signs of malfunction or performance loss.  

We also know that your staff aren’t all IT-lovers like us, so we promise to keep it simple whenever we talk tech!

Instant fixes from our remote helpdesk

We can troubleshoot many issues instantly through our state-of-the-art remote support and monitoring suite. This includes small issues such as “outlook isn’t working properly” through to larger network issues. 

Get an engineer on-site in record time

When you need us on-site, we can be there in as little as 40 minutes—or even sooner for top priority issues. We’re happy to visit you in person so we can deal with any IT issues quickly and get to know your team better.

  • 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!!

  • 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!

Client success stories

Portner Law – Improving security for a London law firm

Within the first 3 months of supporting Portner, we moved their outdated systems to the cloud, increased their security score on a third party cybersecurity penetration test by 80%, digitised their phone systems, implemented a company-wide 2-factor and encryption policy across, and deployed a state-of-the-art backup suite.

Since then, Portner have been able to take the COVID restrictions in their stride thanks to their new remote capabilities. They can access the documents and files they need from home, whilst making phone calls from their office phone numbers via their laptops or mobile devices. And by using Microsoft teams, they’re able to keep departments running smoothly, with clear lines of communication.

Hotspex – Solving remote working issues

Hotspex are a market research company headquartered in Toronto, Canada. The company has a team based in the UK, but still relies on its IT team in Canada for IT support. o21 started working as an extension to the IT team in Canada, acting as their ears on the ground and flagging potential issues.

We identified that the UK team was having issues due to the company’s document archive being based in Canada. Due to the physical distance, accessing files on the archive was painfully slow for people in the UK. To improve the experience, we implemented a local server in the UK that mirrors the archive in Canada, improving read and write speeds by 100x. Hotspex’s internal IT team no longer needs to manage these services remotely, and is now able to focus on improving other areas of the business.
