Built to be the only
IT partner your business
will ever need.
Comprehensive IT Solutions (CITS) was founded on a simple belief: UK businesses deserve a single, accountable technology partner who can handle the full stack — from the boardroom screen to the server room, and from the firewall to the ISO audit.
Company History
Our story &
where we're going.
What started as a small IT support firm serving local businesses in London has grown into one of the UK's most comprehensive technology providers — still with the same commitment to personal service and technical excellence.
-
2010Founded in LondonComprehensive IT Solutions (CITS) was established by a team of ex-corporate IT professionals who believed SMEs deserved enterprise-quality IT support without the enterprise price tag. First 20 clients onboarded in year one.

How We Work
The principles
that guide us.
We're not just a vendor — we're a long-term partner. These values underpin every engagement, every support call, and every project we deliver.
We take full ownership of your technology estate. When something goes wrong, we own it. No finger-pointing between vendors, no grey areas of responsibility — just a single team that's accountable for everything.
Our monitoring tools detect issues before they become problems. We'd rather prevent a server failure at 2am than respond to a crisis at 9am. Proactive management is what separates us from traditional break-fix IT.
Good IT advice means understanding your business. We don't recommend technology for technology's sake — every solution is evaluated against your commercial objectives, budget constraints, and growth trajectory.
Every service we deliver is designed with security as a baseline, not an afterthought. From network architecture to email configuration, we enforce best practice protections without making them a burden on your team.
No surprise invoices. No mid-contract price increases. Every engagement is backed by a clear scope of work, fixed monthly fees, and a plain-English contract. You always know exactly what you're paying for.
Technology evolves. So do we. Our engineers hold active certifications across Microsoft, Cisco, CompTIA, and security disciplines — and we invest continuously in training so your infrastructure is always managed at the highest standard.
Accreditations & Certifications
Standards that
prove our quality.
Our certifications aren't badges on a wall — they're evidence of the processes, controls, and continuous improvement practices that underpin every service we deliver.
Why CITS
What makes us
different.
Many IT companies offer helpdesk support. Very few can genuinely cover everything from cyber security and compliance to CCTV installation and VoIP telephony. We can.
Your dedicated account manager coordinates across all service areas. No bouncing between departments or different suppliers.
From your router to your CCTV to your ISO certificate — we cover infrastructure most IT companies don't touch.
All support — helpdesk, engineering, and account management — is delivered by UK-based staff. No offshore scripted responses.
12, 24, or 36-month agreements — or project-based engagements. We structure arrangements around your business needs.
