Reliable IT support that feels like part of your team

Sonar IT serves small London businesses with reliable IT, honest pricing, and fast, human support. We go the extra mile to keep your systems running and your people supported.

Let’s talk today

Always reachable, and we'll never pass you around

Most small businesses have no idea who’s behind their IT. You wait on hold, talk to someone different every time, and explain yourself over and over again, just to get told a ticket’s been logged.

We built Sonar IT to do the opposite.

You get real engineers who know your business. People who answer the phone, fix the issue, and follow through. And if you need something bigger, you’ve got a named account manager who already knows what’s going on.

91% first-call resolution

We resolve 91% of issues on the first contact. No ticket tag-along. No pass-off. Just results.

99% retention

99% of our clients stick with us, year after year. Not because they’re locked in, but because they want to.

Client retention

From friendly rivals to trusted partners

Josh and Nick started in the same IT apprenticeship, having been told only one of them would be retained. That competition made them better. They both got hired. And soon, they became a team the other techs relied on.

Wherever they worked, whether Josh was migrating full companies to Microsoft 365 or Nick was leading service desks, they kept hearing the same complaint:

“Why do I always speak to someone new?”
“Why do I have to explain myself again?”
“Why does setting up a new PC suddenly cost extra?”

So they decided to find a solution to this. They built Sonar IT with a simple promise: real engineers, predictable costs, and fast support from people who know your business.

Let’s get started

Built on what matters

We’re not just here when things break. We’re here to keep things working, grow with your business, and make IT feel easy.

Reliability

We show up. We respond. We fix things without the faff. If something’s wrong, we’ll sort it, without needing to be told.

Transparency

No guessing. No surprises. You’ll know who’s looking after what, what’s being billed, and what’s coming up, at all times.

Trustworthiness

You get the same people, not a different voice every time. That builds confidence. That builds trust. That’s how we work.

Always improving

Whether it’s training, tools, or time to resolve, we’re always looking for ways to be sharper, faster, and more helpful.

Best support for small businesses

We work best with 10 to 40-user businesses, big enough to need full support, small enough to still care about service.

Based in London, City of London, Greater London and Essex

Serving 10 to 40-user businesses

Trusted by finance, tech, recruitment, and FM companies

Focused on long-term relationships, not quick wins

What we believe about IT support

Support isn’t just about fixing, it’s about preventing, improving, and helping people feel confident with tech. At Sonar, we make IT simple and human.

We’ve worked side by side for 13+ years. Our engineers all have at least 10 years of experience. We’re not junior-heavy, and we don’t waste your time.

With every client, we run a full onboarding project, deliver a free cybersecurity risk assessment worth £1,000, and give you the first month completely free. And if you’re not happy in that first month? We'll pay you £3K for dropping the ball. (T&Cs apply.)
