IT Support London
About Sereno
People-first IT support and cyber security for London businesses that want one accountable team to take ownership of their technology.
We combine deep technical expertise with clear communication and genuine care, giving your people the support, protection and guidance they need to work confidently and securely.
Origin Story
Built for the way businesses work today
After managing successful IT companies for many years, our co-founders, Elizabeth Procopiou and Michael Johnson, recognised that the traditional IT support model was no longer keeping pace with modern business. It was built for a time before hybrid working, cloud technology and today’s cyber security risks.
Sereno was created to offer a different experience.
We bring technology and people together, using smarter systems to remove delays, improve communication and create a reliable, secure and positive technology experience for every business we support.
- Built for hybrid, cloud and always-on working
- Proactive by design, not reactive break-fix
- Technology and people, brought together

What Makes Us Different
More than IT support. A true partnership.
We are not a call centre or a break-fix supplier. We are the team that takes ownership of your technology and stays close to your business as it grows.
Proactive guidance
We do not wait for problems to become urgent. We review your technology, identify risks and help you plan improvements before they affect your people, security or growth.
IT and cyber security together
Support and security should not operate separately. We manage both as one joined-up service, protecting your users, devices, systems and data without adding unnecessary complexity.
Our Mission
To be London’s most innovative and people-centric IT support company.
We will achieve this by continually improving the technology experience we provide for our clients and our people, investing in better systems, developing our team and designing every part of our service around the people who rely on it.
How We Support Fast-Growing Businesses
IT support that keeps pace with your business
As your team grows, so do the demands on your systems, security and people. Sereno gives you one accountable team to manage the day-to-day, reduce risk and help you plan what comes next.
-
Direct access to experienced engineers
Get help in the way that works best for your team. Book time directly with an engineer for more involved issues or use live chat when you need a quick answer. No call-centre runaround, unnecessary handovers or repeatedly explaining the same problem.
-
Dependable day-to-day IT management
We take ownership of the technology your people rely on every day. From support requests, devices and users to Microsoft 365 or Google Workspace, onboarding, offboarding and ongoing maintenance, we keep everything working without IT becoming another internal burden.
-
Security built into your IT
Cyber security is part of how we manage your technology, not an optional extra added later. We help protect your people, devices and data through practical controls, monitoring, guidance and continuous improvement as your business evolves.
-
Strategic advice for what comes next
We help you look beyond today’s support requests and make better long-term technology decisions. Your Technology Advisor works with you to understand your priorities, review risks and build a practical roadmap through regular reviews and our Technology Review Platform.
-
You invest, we invest
When you invest in strengthening your technology and cyber security, Sereno invests alongside you. Eligible Partners can benefit from reduced monthly fees as their security improves, alongside support with cloud migrations and selected technology projects.
-
A service measured around your experience
Our service team is focused on customer satisfaction, not simply meeting SLAs or closing requests as quickly as possible. Our Customer Experience Agreement shapes how we deliver support, measure performance and hold ourselves accountable, keeping your people and their experience at the centre of the service.
Support in Action
We are here when it matters most
When something stops working, your team needs more than an automated acknowledgement. They need someone taking ownership and getting people back to work quickly.
- A clear response and regular communication
- We fix the cause, not just the symptom
- Monitoring and improvement behind the scenes
The result is fewer surprises, less internal IT administration and more confidence in the technology your business depends on.

True Partnership
We succeed when our clients succeed
We believe the best IT relationships are built on shared goals, clear communication and mutual trust. That means understanding your business rather than treating you like another account number.
It means recommending what will genuinely improve your organisation, not what creates the largest project. And it means being accountable for the service we provide, from the smallest support request to the biggest technology decision.
Our clients are our partners, and their success shapes everything we do.
