IT outsourcing London: what it actually means for your business

Most businesses that come to us have the same story. IT is being managed by someone who also does something else – the office manager, the finance assistant, or a part-time contractor who turns up when things break. When something goes wrong, it costs more than it should and takes longer than it should. And nobody is watching the system in between.

IT outsourcing changes that arrangement entirely. Instead of reacting to problems, you have a team that prevents them. Instead of unpredictable invoices, you have one fixed monthly cost that covers every user on your network. Instead of chasing a contractor, you have a helpdesk that answers.

IT outsourcing in London has a reputation it does not deserve — often associated with offshoring, cost-cutting, or handing your business over to a faceless call centre. Lanmark is none of those things. We are a local team based 15 minutes from the City of London, with a 30-year track record of keeping London businesses running. Outsourcing your IT to us means handing ownership of a critical function to people who do nothing else, at a fixed monthly cost that does not change regardless of what happens on your network.

What Lanmark’s IT outsourcing service includes

When you outsource your IT to Lanmark, one monthly per-user fee covers all of the following — irrespective of the number of devices you have:

Unlimited helpdesk support

for every user, every device. Every call is answered by a qualified engineer capable of resolving your problem within 30 minutes, whether by walking you through it, taking remote control of your workstation, or arranging a site visit. No per-incident charges, no ticket limits.

24/7 proactive monitoring

of your entire infrastructure. A dedicated monitoring team analyses alerts from across your network around the clock, responding to outages and security threats before they affect your business.

24/7/365 Managed Detection and Response (MDR)

a dedicated security operations centre staffed by security analysts who respond to cyber threats in real time, isolating and preventing attacks such as ransomware and hacking. This is enterprise-grade protection delivered at a cost that works for businesses of your size.

Microsoft 365 management

licensing, configuration, user provisioning, and ongoing administration, including a free licence review to ensure you are not paying for seats you do not need.

On-site IT support

when remote resolution is not sufficient — we are based in Holborn and Dartford, so response times are practical, not theoretical.

A named service delivery manager and assigned technician

who know your business, your infrastructure, and your team. Monthly service reports covering helpdesk usage, device availability, network monitoring, and patch status. Regular service review meetings included as standard.

Annual IT strategy and budget planning

a thorough assessment of your infrastructure each year, resulting in a tailored twelve-month IT plan and a project-based budget spreadsheet.

There are no hidden fees for hardware issues, or users joining mid-month. The per-user model means your costs scale predictably as your business grows.

Why London businesses choose Lanmark

For IT outsourcing, London businesses often struggle to find a provider that combines genuine local presence, unlimited support, and enterprise-grade security at a cost that works for an SMB. Here is what makes Lanmark different.

Pricing that makes sense

Most IT providers charge per device, per incident, or per hour. We charge per user — a simple monthly fee, irrespective of how many devices that person uses. One number, per person, per month, covering everything. For a Finance Director trying to plan ahead, that predictability matters considerably more than a lower headline rate that comes apart in the small print.

A Microsoft accreditation held by very few

Lanmark holds Microsoft’s Support Service Designation — an accreditation awarded to only a handful of companies worldwide. It confirms that our technical standards, service processes, and support quality have been independently assessed by Microsoft. It is not a badge we purchased; it is a standard we passed.

Genuinely local

Our offices in Holborn (Waterhouse Square, EC1N) and Dartford mean we are accessible to the businesses we serve — physically, not just on a call. If something needs on-site attention, we can be there. We are not a remote-first provider routing your tickets through a distant team.

The numbers speak for themselves.

87% of calls answered within 15 seconds. Average response time: 11 minutes. Average resolution time: 26 minutes. First contact resolution rate: 78%. Customer satisfaction: 99.5%. These are not aspirational targets — they are our current service desk performance figures.

Three decades of experience

Lanmark has been managing IT for London businesses since 1995. We have operated through the shift to cloud, the rise of remote working, and the escalation of cybersecurity threats. We know what changes and what does not.

Security is not an add-on

Our 24/7 Managed Detection and Response service is included as standard — not sold as an optional extra. The threat landscape for London SMBs has changed significantly in recent years. Security monitoring should not be something you get around to.

Switching is easier than you think

The most common reason businesses stay with an under-performing IT provider is not loyalty – it is the fear of disruption during the transition. That is a legitimate concern, and it is why Lanmark created SmoothSwitch.

SmoothSwitch is our structured, risk-free migration programme, designed to move you from your current provider to Lanmark without disruption to users, data, or daily operations. It includes a free 30-day support trial so you can experience our service desk before you commit, zero-cost onboarding (we document your infrastructure and deploy monitoring at no charge), and a 30-day dual-run period during which both Lanmark and your incumbent provider receive every ticket — so nothing is missed during the handover.

Any outage directly caused by Lanmark in the first 60 days is remedied at our cost. And if you decide within 30 days of go-live that we are not the right fit, you can exit with no financial penalty and take your data and documentation with you.

Put simply, SmoothSwitch removes every practical barrier to making the switch, and lets you judge us on performance before you make a long-term commitment.

FAQ’s

The questions below cover what our prospective IT outsourcing London clients ask most frequently before making the switch.

Lanmark’s managed IT outsourcing is priced per user per month, covering all support, monitoring, and management with no additional charges for standard business-as-usual activity. Any project work outside BAU is quoted upfront before anything is agreed. The best way to get an accurate figure for your business is to book a free IT health audit — we will assess your current setup and give you a clear, comparable number.

A break-fix supplier arrives when something has already gone wrong and charges you for the time it takes to fix it. There is no monitoring between visits, no ownership of outcomes, and no predictability in what it will cost. Outsourcing to a managed provider like Lanmark means your IT is actively maintained and monitored at all times, problems are caught before they become failures, and your monthly cost is fixed regardless of what happens on the network.

Our SmoothSwitch onboarding programme includes a 30-day dual-run period during which both Lanmark and your current provider receive every support ticket simultaneously. This ensures nothing is missed during the handover and your team experiences no disruption. If your current provider is uncooperative with the transition, we provide a legal transfer-of-service notice and asset-handover checklist as part of the programme.

No. Our per-user monthly fee covers all standard managed IT support. Any project or infrastructure work that falls outside business-as-usual activity is scoped and quoted separately before it begins. There are no out-of-hours surcharges for support calls within the managed service.

Yes. We manage IT for users working in the office, at home, and anywhere in between. Our support covers cloud-based infrastructure, Microsoft 365 environments, mobile devices, and remote access systems. Location is not a limitation — support is provided to users wherever they are working.

Our primary office is in Holborn (Waterhouse Square, EC1N), with a second office in Dartford serving clients across the wider South East. For clients with cloud-first infrastructure, we work with businesses throughout the UK. On-site visits are available next business day across the UK when required.
