From the director

"Get a real expert on the phone in 20 seconds, every time"

18 years ago, I founded London Systems based on a simple idea: when you need IT help, you shouldn't have to wait.

I've built the team this way on purpose. We're available 24/7, and we answer fast. I also believe great IT support starts with knowing the people behind the business.

So we build real relationships, understand what makes you different and shape our support around your business needs.

Why Choose us?

IT support that shows up and delivers

A real person in 20 seconds is just the start. You also get experienced people, stronger security, and a team that takes responsibility from day one.

18 years experience, ISO 27001 certified

We've supported London businesses for nearly two decades. We hold ISO 27001, ISO 9001 and Cyber Essentials Plus, independently audited, not self-declared.

IT, security and compliance expertise, under one roof

Most providers pick one and outsource the other. We've built real depth in both, so there's no gap between vendors for something to fall through.

We price-match, with best value guaranteed

Found the same quality of IT support for less? We’ll match it, while guaranteeing the best value. You always get the best deal here.

We handle your full MSP switch

We'll contact your current provider, manage the paperwork and handle the transition for you from start to finish, with no disruptions.

Free onsite visit in month one

You get an engineer in your building, meeting your team and seeing your setup first-hand. Personal relationship from day one, not from month six.

If we ever fall short, your next month is free

If we don't deliver on what we promised, your next month is free, automatically. That's how seriously we take our word.

Fantastic IT support team, diverse and flexible range of hosted services. Would highly recommend them to any SME business seeking quality IT services.

Paul Davies

‘London Systems are responsive and very human – refreshingly so given the organisation they replaced. They are keen to understand how our IT requirements will evolve over time – rather than just solving issues that occur in the moment.’

Fleur Holland-Haque

‘London Systems have been there when I needed them and I now understand the value of having a ‘go to’ person, my Account Manager.’

Peter Copus

‘We had complete faith in London Systems during our office relocation, this challenging period; we needed to keep operational whilst undergoing very impactful changes.’ ‘We were supported at every step and there were no issues or major problems during the whole of the project relocation. We are delighted with the final solution and continue to enjoy a strong partnership with London Systems.’

Peter Dalton

‘London Systems assisted us with a complete migration to a new IT system. The migration was seamless from start to finish thanks to London System’s professionalism and expertise. We continue to work closely with them and their Help Desk team who are all dedicated to responding quickly with relevant advice and solutions.'
