Your Dedicated IT Department
Our Approach to IT Excellence
A structured methodology ensures exceptional service delivery and measurable results for every client.
Assessment
We thoroughly evaluate your current IT infrastructure — identifying strengths, weaknesses, security gaps, and opportunities for improvement.
Planning
Our team develops a customised IT strategy aligned with your business goals, budget, and technological requirements — clearly documented and agreed.
Implementation
We execute the plan with precision — minimising disruption to your day-to-day operations during transition, with clear communication at every stage.
Management
Ongoing monitoring, maintenance, and support ensures your IT systems remain optimised, secure, and aligned with your evolving business needs.
Why Choose 19 Computing for IT Support?
We've been supporting businesses across Portsmouth and Hampshire since 2014. Our IT support isn't call centres and ticket queues — it's real engineers who know your systems and respond within the hour.
Same-Hour Response
When your network goes down, you don't wait days. Our Portsmouth-based team responds within the hour for critical issues, and same-day for everything else. No offshore call centres, no ticket queues.
Dedicated Engineer
You get a named engineer who knows your systems, your team, and your setup. Not a different voice every time you call. Your engineer documents everything so nothing falls through the cracks.
Proactive Monitoring
We monitor your servers, workstations, and network 24/7. We spot problems before they become outages — patching vulnerabilities, replacing failing drives, and optimising performance before you even notice.
On-Premises & Cloud
Whether your infrastructure is in a server room on-site or spread across AWS, Azure, and Microsoft 365, we manage it all. Hybrid setups are our speciality — we bridge the gap between local and cloud.
Cybersecurity First
Every support plan includes cybersecurity essentials: endpoint protection, email filtering, firewall management, and security patching. We've protected Portsmouth businesses from ransomware, phishing, and data breaches since day one.
Local to Portsmouth
We're based on Durham Street, a short walk from Fratton station. When you need someone on-site — at your office in Gunwharf, your warehouse in Hilsea, or your practice in Southsea — we're there fast.
How Our IT Support Works

We visit your Portsmouth office, assess your current systems, identify risks and opportunities, and present a clear plan. No obligation, no jargon, no hard sell — just honest recommendations.
