Managed IT, security and Microsoft 365 from a team that puts people first.
Your London IT partner
Solid Systems: a human-centric IT company in London.
Solid Systems is an IT company with an office in Mill Hill, north-west London. We look after London businesses with managed IT, IT support, cyber security, Microsoft 365 and Copilot adoption, so technology works for your people and someone answers when it doesn’t. The company was founded in Cape Town in 2003 and has offices in London, Cape Town and Johannesburg.
We start with the people, not a product list. Before we recommend anything, we learn how your business runs: who does what, which systems your teams can’t work without and where the working day gets slowed down. Then we fix the causes, so the same problem doesn’t come back next month.
That is what we mean when we say we’re human, not robots. Technology is there to make work easier for the people doing it, and every recommendation we make has to earn its place on those terms.
IT support in London
What London businesses get from us.
Few London teams work from one desk any more. People split the week between home and the office, meet clients across town and expect their laptop, phone and files to behave the same wherever they open them. Our support is built for that. Most requests are handled over a secure remote connection, so the fix starts as soon as the right person picks up the ticket, wherever the user happens to be sitting.
Every request is logged at our helpdesk, sorted by urgency and given to the right IT pro, so nothing depends on someone remembering an email. In the background, Solid Guardian keeps an eye on devices, servers and backups, and raises the alarm about a full disk or a failed backup before it stops anyone working.
What a London client gets from us:
- A helpdesk your people reach by email or phone, with every request tracked until it is closed
- Monitoring and patching for laptops, desktops and servers, so problems are spotted early
- Microsoft 365 administration: starters and leavers, licences, Teams, SharePoint and security settings
- Identity, device and email protection through Secure365
- Regular planning with a virtual CIO, so your technology keeps pace with the business
Having an office in London means you deal with a company that has a London address and a UK phone number. When a job needs someone on site, we agree with you upfront how it will be handled.
What we do
What IT services does Solid Systems offer in London?
Most clients begin with managed IT services or security and grow into Microsoft 365 and Copilot.
Managed IT services
One agreement for support, monitoring, patching and backup, run by people who know your setup. Our guide to Solid Select and Solid Unlimited explains the two plans.
Managed IT services →Cyber security
Secure365 closes the gaps attackers use most: stolen passwords, phishing emails and unprotected devices. It starts with an assessment, so you can see where the real risks are.
Cyber security →Microsoft 365
Teams, SharePoint, OneDrive and Intune set up so people find what they need and can work from anywhere, with licences matched to what each person uses.
Microsoft 365 →Copilot and AI adoption
Helping your people use Microsoft Copilot well in everyday work, starting with the data and permissions that keep it safe to switch on.

How we work
Five steps, from first review to the next plan.
Every London client goes through the same five steps, which we call The Solid Way. The pace changes from business to business; the order doesn’t.
- Review. A Solid Systems Review looks at your devices, accounts, Microsoft 365 use and security, and turns what we find into a roadmap your leadership owns.
- Switch. If you are moving from another provider, we take over in a planned way: scope agreed, everything documented, access and ownership handed across.
- Secure. Identity, devices and data are protected before anything new is added, so growth doesn’t open new gaps.
- Adopt. We coach leaders and teams so Microsoft 365 and Copilot become daily habits rather than licences nobody uses.
- Evolve. Regular reviews keep the roadmap current as the business, the threats and the tools change.
You approve each step before it starts, and you know what onboarding costs before you sign anything.
Who we are
An exceptionally human IT company in London.
Solid Systems was started in Cape Town in 2003 by Daniel Avinir and Michael Claxton, and it still runs on the idea they began with: good technology should leave people with more time and less frustration. Today we have offices in London, Cape Town and Johannesburg.
We are open about where we come from. A South African company with a London office gives our clients a team that has spent more than two decades solving technology problems for very different businesses, and a partner that is used to working across borders.
If your business also has people in South Africa, they get the same helpdesk, the same standards and the same way of working, with our Cape Town and Johannesburg offices nearby.

01Where is your London office?
Our London office is at Mill Hill Industrial Estate, 7 Flower Lane, London NW7 2HU, in north-west London. You can call it on +44 20 3150 0261 or send us a message.
02Is Solid Systems based in the UK or in South Africa?
Solid Systems was founded in Cape Town in 2003 and is based in South Africa, with an office in London for our UK clients and another in Johannesburg. London clients have a London office and a UK phone number to call, backed by the whole team.
03What IT services do you offer London businesses?
Managed IT services, IT support, cyber security, Microsoft 365 and Copilot adoption, plus IT consulting and Microsoft licensing. Most clients begin with managed IT or security and add the rest as they grow.
04How does IT support work for a hybrid team?
Most requests are fixed remotely. Your people email or call the helpdesk, the ticket goes to the right IT pro, and with your permission they connect securely to the device and fix it. Because Microsoft 365 and our monitoring work wherever the laptop is, it makes little difference whether someone is at home or in the office.
05How do we get started?
Book a 30-minute consultation. We’ll talk about how your business runs and where IT gets in the way, and tell you honestly whether we’re the right fit. If we are, the next step is usually a Solid Systems Review of your current setup.
