What outsourced IT means for your business

Outsourced IT is the decision to hand the full responsibility for your technology to an external partner, rather than employ that capability in-house. In practice that means no internal IT headcount to recruit, manage and retain, no per-incident bills when something breaks, and no scramble to find a specialist when a project lands. One monthly cost, agreed in advance, covers the entire IT function.

For a London SMB, the most common reason to take this route is not cost on its own. It is predictability. A finance director can budget a fixed per-user number for the year. An operations director knows that every request, from a forgotten password to a Microsoft 365 migration, is handled inside the same agreement. A managing director gets back the time previously spent triaging IT supplier escalations.

The model also covers the parts of IT that an internal hire often cannot reach. Twenty-four-hour security monitoring, Microsoft Direct CSP licensing buying power, formal patching and compliance routines. A capable outsourced IT partner brings these as standard, not as separately priced add-ons.

Why London SMBs choose fully outsourced IT with Lanmark

Per-user pricing, not per-device

One number per user per month, agreed at the start, applied to every user inside the agreement. No hidden device fees, no per-ticket charges, no surprise invoices when usage rises in a busy quarter. The model is built for a finance director who needs to forecast IT cost for the year and a managing director who does not want to spend management time on supplier billing disputes.

Microsoft Support Service Designation

Lanmark holds the Microsoft Support Service Designation, the highest level of Microsoft support partnership available, awarded only to a handful of partners worldwide against verified technical and customer-outcome criteria. For a London SMB that runs on Microsoft 365 and Azure, that designation is the most direct evidence available that a partner can carry the workload end to end.

Enterprise-grade security at SMB pricing

Most mid-market firms pay a six-figure annual bill for a 24×7 Managed Detection and Response service. Lanmark packages MDR and a Security Operations Centre inside the per-user model, so an SMB gets the same eyes-on-glass security posture without the mid-market price tag. For an outsourced IT engagement, security is not a separate line item.

Local team, three decades

The Holborn office gives Lanmark London proximity for the meetings and on-site work that genuinely benefit from it. The Dartford head office anchors the operations. The business has been doing this since 1995. Outsourced IT is not a side line, and Lanmark is not a remote-only call centre or a recent entrant to the London market.

Who we work with

Lanmark’s typical client is a London SMB between 20 and 500 users, most often in professional services, finance, legal, retail head-office, accountancy, consultancy or agency work. Decision-makers are usually MDs, FDs or operations directors rather than dedicated IT staff. The pricing model and service shape apply equally to businesses outside those named sectors, and several Lanmark clients sit outside the typical sector list.

How an outsourced IT engagement with Lanmark works

1. Free IT review. A no-obligation conversation and a light-touch audit of your current setup, costs and risks. Output is a written summary of what is working, what is not, and where you are over-paying or exposed.

2. Tailored proposal. Per-user pricing, scope of cover, transition plan, and a clear set of service measures. You get the numbers before any commitment.

3. Onboarding. Knowledge transfer, documentation, user setup and security baseline, typically completed inside 30 days. The aim is no service drop during transition.

4. Ongoing partnership. Day-to-day support, proactive maintenance, monthly service reviews, and a named account manager who knows your business and the people in it.

Frequently asked questions

What does outsourced IT cost for a London business?

Outsourced IT is priced per user per month, so the total cost is driven by user count and the security tier you choose. As a working range for a London SMB, expect to budget in the low to mid tens of pounds per user per month for the core managed support and helpdesk cover, with a higher tier for businesses that need 24×7 MDR/SOC and advanced Microsoft 365 security. The free IT review produces a specific number against your actual estate before any commitment.

What is the difference between outsourced IT and managed IT?

Outsourced IT is the decision to transfer full responsibility for the IT function to an external partner, including the helpdesk, security, infrastructure, cloud and licensing. Managed IT typically refers to a defined set of services supplied alongside an in-house IT capability, for example a managed firewall or a managed backup service. Lanmark provides both. This page covers the fully outsourced model, where the partner becomes the IT department.

How do you handle cyber security as part of outsourced IT?

Cyber security is built into the core service. Every outsourced engagement includes 24×7 Managed Detection and Response, a Security Operations Centre, identity and access controls aligned to Microsoft 365 best practice, formal patching routines, and the policy and compliance work to support Cyber Essentials certification. Higher-risk sectors can add managed cyber security for London businesses as an enhanced layer.

Will you support our existing Microsoft 365 tenant and licensing?

Yes. Lanmark is a Microsoft Direct Cloud Solution Provider, which means we can take over both the support of your existing tenant and the billing for your Microsoft 365 licences. If you prefer to keep your licensing where it is, that is fine too. As part of onboarding we run a free Microsoft 365 licence review and surface any over-spend or mis-tiering before the agreement starts.

How quickly can you take over our IT?

A typical transition completes inside 30 days. Smaller estates can be faster, and more complex migrations involving on-premise infrastructure or a tenant move take longer. The onboarding process is structured so that day-to-day service continuity is preserved throughout the transition. You will not be left without support while the handover happens.

Do you cover hybrid and remote users across the UK?

Yes. Hybrid working is the norm rather than the exception for Lanmark clients. The outsourced IT service covers users wherever they work, from the central London head office to a Kent commuter town or a UK regional site. Support is delivered remotely as standard, with on-site engineer attendance available when the work genuinely needs hands on keyboard.

Outsourced IT with Lanmark is predictable in cost, complete in cover, and delivered by a Microsoft-accredited team that has been supporting London SMBs since 1995. The free IT review is the lowest-friction way to find out what your current setup is costing you, where you are exposed, and what a per-user model would look like for your business.
