Lanmark provides managed IT support for small and growing businesses across London. Our service covers everything from your help desk and devices to your network infrastructure and cybersecurity — all on a single, predictable monthly cost per user. As holders of Microsoft’s Support Service Designation, an accreditation held by fewer than a dozen companies worldwide, we bring enterprise-grade capability to businesses that do not need — or cannot justify — an in-house IT team. For small businesses ready to take the next step, our AI consultancy service helps you adopt Microsoft 365 Copilot safely and measure the productivity gains.
What does IT support for a small business actually include?
For most small businesses, IT support means having someone to call when something breaks. That is a reasonable starting point, but it leaves a significant gap: everything that happens between the phone calls.
Managed IT support from Lanmark covers the full picture. That means a dedicated help desk available when your team needs it, proactive monitoring of your systems and network so problems are caught before they cause disruption, device management across all your laptops, desktops, and mobile devices, software updates and patching handled automatically, and a security layer that goes well beyond a standard antivirus product.
The simplest way to think about it: a managed IT support contract gives a small business the equivalent of a full IT department, without the overhead of hiring one. You get skilled engineers, monitoring systems, and an escalation path — all included in a monthly fee.
Why do small businesses choose managed IT support over ad-hoc help?
Many small businesses start out with an informal IT arrangement — a contact who helps when things go wrong, or a member of staff who is “good with computers.” This works until it doesn’t. The problems tend to compound: systems that were never set up properly, security gaps that go unnoticed, and an expensive scramble every time something breaks.
The core issue with ad-hoc, break-fix IT is that the incentives are misaligned. A provider who charges by the hour has little motivation to prevent problems — each fault is a billable event. Managed IT support flips this dynamic. Lanmark is motivated to keep your systems running reliably because that is what the service is built to deliver. When something goes wrong, there is no invoice to accompany it.
For a small business in London, the switch from reactive to proactive IT support typically results in fewer disruptions, more predictable costs, and a clearer picture of what is actually running on your network.
How Lanmark’s per-user pricing works
Lanmark’s managed IT support is priced per user, not per device. This distinction matters more than it might seem.
Most IT support contracts are priced per device — your laptop, your desktop, your server, each charged separately. For a small business, this creates complexity: staff who use multiple devices cost more, adding a new machine requires a contract amendment, and the monthly bill rarely looks the same twice.
Per-user pricing removes all of that. Each member of staff is covered regardless of how many devices they use. The monthly cost is consistent and predictable. When you hire someone new, the cost scales in a straightforward and proportionate way. When someone leaves, it scales back down.
There are no per-incident charges, no call-out fees, and no bill at the end of a difficult month because your systems had a bad week. Support is unlimited. This is the model we think small businesses deserve — and it is the model we have built our service around.
Our accreditation as a Microsoft Support Service Designation holder is one marker of the standard we operate to. It reflects a level of technical capability and service quality that very few IT providers in the UK can demonstrate.
Cybersecurity for small businesses — why it matters more than you think
Small businesses are a preferred target for cyber attackers. This is not intuition — it is well-documented. The National Cyber Security Centre (NCSC) consistently reports that small and medium-sized businesses face a disproportionate volume of phishing attacks, ransomware campaigns, and business email compromise attempts. The reason is straightforward: smaller organisations tend to have less mature defences, less internal expertise, and valuable data worth targeting.
The response most small businesses default to is an antivirus product. Antivirus catches known threats. It does not catch attackers who use legitimate tools, compromised credentials, or novel techniques — which is how most successful attacks now work.
Lanmark’s Managed Detection and Response (MDR) service provides 24/7 monitoring of your systems by a dedicated Security Operations Centre (SOC). In plain terms: a team of security analysts watches your environment around the clock, looking for signs of attack or compromise that automated tools would miss. If something is detected, the response is immediate rather than waiting for you to notice a problem at 9am on a Monday.
This level of security was, until recently, the exclusive preserve of large enterprises. Lanmark makes it accessible to small businesses at SMB pricing. It is not an optional extra — it is increasingly a baseline requirement, particularly for businesses that hold client data, financial records, or operate in regulated sectors.

Microsoft 365 — the backbone of most small businesses
The majority of small businesses in London now run on Microsoft 365 — email, file storage, Teams, and increasingly, the applications their staff use every day. As a Microsoft Direct Cloud Solution Provider (CSP), Lanmark supplies M365 licences at discounted rates and manages the configuration, migration, and ongoing support of your Microsoft environment.
If you are unsure whether your current M365 licences are the right ones for your business — a common issue — we offer a free licence review. Many small businesses are paying for licences they do not need, or missing features included in their existing plan that they are simply not using. The review takes no more than an hour and typically results in either a cost reduction, a capability improvement, or both.

Frequently asked questions
How much does IT support for a small business in London cost? Lanmark’s managed IT support is priced per user, per month. The exact cost depends on your user count and the level of service you require. We do not publish a standard rate because each business has different infrastructure and support needs — but the per-user model means the cost is always transparent and proportionate. Contact us for a straightforward conversation about your requirements.
What is the difference between managed IT support and a break-fix service? A break-fix service means you pay when something goes wrong. Managed IT support means you pay a fixed monthly fee and the provider is responsible for keeping everything running. For any business that depends on its technology to operate — which is most businesses — managed IT support reduces downtime, eliminates unexpected bills, and shifts the responsibility for your IT health to the provider.
Do you provide IT support for businesses with fewer than 20 employees? Lanmark’s primary focus is businesses in the 20-500 user range, where the managed service model delivers the most value. For smaller organisations, our starting requirements may apply — please contact us to discuss your specific situation.
What happens if something goes wrong outside business hours? Lanmark’s Managed Detection and Response service monitors your environment 24 hours a day, seven days a week. For general IT support issues outside of agreed service hours, your service agreement will specify the response arrangements. We are happy to discuss out-of-hours cover as part of any service conversation.
Do we need to sign a long-term contract? Lanmark builds long-term relationships with its clients — most have been with us for years. We do not use punishing contract terms to retain clients. If a business wants to work with us, it should be because the service is good, not because leaving is difficult.
How quickly can you respond if our systems go down? Response times are agreed as part of your service level agreement and vary depending on the severity of the issue. Critical failures receive immediate attention. Because Lanmark’s monitoring systems flag problems proactively, many issues are identified and resolved before they result in visible disruption to your business.
