Managed IT Services London, Unlimited Support, One Monthly Price
Managed IT services allow London businesses to outsource their entire IT infrastructure, helpdesk, and security to a specialist provider on a predictable, fixed monthly fee. Instead of hiring internal IT staff or paying for ad-hoc repairs, a managed IT services provider monitors your systems 24 hours a day, handles all maintenance and updates, resolves problems before they impact your business, and scales as you grow. For London SMBs in professional services, finance, legal and regulated sectors, managed IT services are no longer optional. They are essential infrastructure that protects revenue, data, and reputation while freeing in-house teams to focus on core business. Lanmark Limited has been providing managed IT services to London and Southeast England businesses since 1994, and holds the Microsoft Support Service Designation, a credential earned by only a handful of companies worldwide and awarded only where Microsoft’s highest standards for security, stability and support quality are met.
Not sure what your current provider actually covers? We will review your setup, identify the gaps, and give you a fixed monthly price. Free, and no obligation.
What Managed IT Services Include
Managed IT services are an all-in-one package designed to handle every aspect of your technology infrastructure. Here’s what you get:
Unlimited Helpdesk and User Support
Your team can call or email the Lanmark helpdesk whenever they need help, with no per-incident charges, no ticket limits, and no waiting for a callback. Our engineers support employees on Microsoft 365, Windows, macOS, mobile devices, VoIP systems, and business applications. Problems that would normally cost £150-£250 per incident to fix are included in your monthly service charge. Everyday questions can also be answered immediately through TekFix AI, our AI support assistant, which walks a user through guided troubleshooting in plain English and hands anything more involved to a Lanmark engineer with the diagnostics and chat history already attached.
24/7 Proactive System Monitoring
We monitor your servers, workstations, backups, and security systems around the clock. Our monitoring tools alert us to problems (failed backups, disk space issues, failed patches, security alerts) the moment they occur, often before you notice them. This proactive approach means most issues are resolved overnight, while you sleep.
Patch Management and Operating System Updates
Security patches and software updates are tested, scheduled, and deployed across your entire estate on your preferred schedule. We handle Windows Server updates, Microsoft 365 patches, third-party application updates, and firmware releases without manual intervention, reducing your attack surface and eliminating the risk of staff accidentally installing incompatible software.
Asset Inventory and Lifecycle Management
We maintain an up-to-date record of every device you own, including hardware specifications, software licenses, warranty status, and end-of-life dates. This ensures you know exactly when equipment needs replacing and are never caught out by surprise hardware failures or unsupported software. Where buying hardware outright is not the preferred route, PC as a Service folds the devices themselves into the same monthly per-user fee, with a refresh built into the agreement rather than a capital decision every few years.
Onsite Support When Needed
For issues that cannot be resolved remotely, our engineers visit your offices the same day or next day, depending on priority. Network cabling, hardware replacement, physical security assessments, and user training are all part of the service.
Security Baseline and Best Practice Configuration
We configure all systems according to Microsoft security baselines and recognised industry standards, including CIS Benchmarks and NCSC guidance. This includes firewalls, antivirus, multi-factor authentication, email security, data loss prevention, and regular security reviews, all included, not as costly add-ons.
Why London SMBs Choose Lanmark for Managed IT Services
Microsoft Support Service Designation
Lanmark is one of only a handful of companies worldwide to hold Microsoft’s Support Service Designation. This certification is not awarded lightly. It requires continuous training, annual audits, and demonstrable expertise in Microsoft cloud services (Microsoft 365, Azure, Teams). When you work with a Support Service Designated provider, you have direct access to Microsoft’s support channels for complex issues, and your infrastructure is configured to Microsoft’s highest standards.
Unlimited Per-User Pricing, No Surprises
Most MSPs charge per device, per hour, or per incident. Lanmark charges a single monthly fee per user, which covers everything: helpdesk calls, on-site visits, monitoring, patches, backups, and standard security. You know your IT costs in advance, and you never face a shock bill because someone had a technical emergency.
30+ Years of Proven Reliability
Founded in 1994, Lanmark has supported London and Southeast England businesses through multiple technology cycles, security incidents, and business disruptions. We know the sectors we serve (professional services, finance, legal and retail) and understand the specific compliance and security requirements each sector demands.
24/7 Security Monitoring
Your systems are monitored continuously, every day of the year, including nights, weekends, and bank holidays. If a security alert fires at 2 a.m., our SOC team is already investigating it. If a backup fails on a Sunday, it’s been detected and being resolved.
London and Dartford Based
We are headquartered in Dartford and maintain service engineers across London. Fast response times and local support are not afterthoughts. They are built into our service model. The same engineers cover the county from that Dartford base, which is set out in more detail on our IT support in Kent page.
Managed IT Services Pricing, How It Works
Managed IT services pricing at Lanmark is simple: a fixed monthly fee per user (employee or contractor who needs IT support), regardless of how many devices they use or how often they call the helpdesk.
Why Per-User Pricing?
A per-user model reflects how business IT actually works: each person needs support, and that support should be predictable. If you employ 50 people, you pay for 50 users. If you grow to 60 people, you pay slightly more. If someone leaves, you pay less. No per-device charges, no per-incident surcharges, no capacity surprises.
What’s Included?
The monthly fee includes unlimited helpdesk, 24/7 monitoring, standard patches and updates, onsite support when needed, basic antivirus, email filtering, mobile device management, and security configuration. MDR/SOC services (advanced threat monitoring and response) are optional add-ons, priced separately based on your threat profile.
Scaling with Growth
As your business grows, managed IT services scale with you. Your monthly cost increases, but your per-user cost typically decreases, and you never need to stop operations to implement new infrastructure or renegotiate contracts.
Comparison to Break-Fix IT Support
With break-fix (paying per incident), an unexpected server failure, ransomware incident, or data loss event can cost thousands of pounds and take days to resolve. With managed IT services, most problems are detected and resolved proactively, and your total IT spend is predictable regardless of what goes wrong.

Who We Support
Lanmark managed IT services are designed for London and Southeast England SMBs with 20 to 500 employees. Typical clients include:
Businesses at the smaller end of that range weigh the decision differently, and what changes at that size is set out on our IT support for small businesses in London page.
Professional Services
Consulting firms, accountancies, and business advisory practices rely on Lanmark to manage client data securely, scale systems as project teams grow and shrink, and maintain GDPR compliance. These firms cannot afford downtime or data breaches, and managed IT services ensure both are rare.
Finance and Accounting
Financial services practices, mortgage brokers, and accounting firms handle sensitive client data and must meet FCA and GDPR requirements. Lanmark’s managed IT services include the security controls, audit trails, and compliance documentation these firms need.
Legal Practices
Law firms and legal departments have strict confidentiality obligations and require secure file handling, encryption, and access controls. Managed IT services provide the infrastructure to meet those obligations.
Retail and Hospitality
Retail chains and hospitality businesses use managed IT services to manage point-of-sale systems, staff schedules, and customer data across multiple locations. Lanmark supports both central servers and distributed branch networks.
Regulated Industries
Any business handling personal data, financial information, or regulated content benefits from managed IT services. The compliance, audit, and security frameworks built into the service reduce regulatory risk.
Frequently Asked Questions
Q: What is a managed IT services provider?
A managed IT services provider (MSP) is a company that takes responsibility for your entire IT infrastructure (computers, servers, networks, security and helpdesk support) on behalf of your business. Instead of hiring IT staff in-house, you outsource those functions to the MSP under a service level agreement. The MSP monitors your systems, handles routine maintenance, resolves problems, and ensures your technology environment is secure and running smoothly. Lanmark is a managed IT services provider; we take on the day-to-day responsibility for technology so your team can focus on running the business.
Q: How much do managed IT services cost in London?
Lanmark’s managed IT services are priced per user on a monthly basis. The cost depends on the number of employees needing support, the complexity of your environment, and which optional services you add (such as MDR/SOC security monitoring). For a typical London SMB with 30-50 employees, managed IT services typically cost between £30 and £50 per user per month, though larger businesses may negotiate lower per-user rates.

Q: What’s the difference between managed IT services and break-fix IT support?
Break-fix IT support means paying per incident when something goes wrong. You call when you have a problem, an engineer fixes it, and you receive an invoice. This approach is reactive and often expensive. Managed IT services, by contrast, are proactive and predictable: you pay a fixed monthly fee, and the MSP monitors your systems continuously to prevent problems before they occur. Break-fix can lead to surprise bills, downtime, and security gaps. Managed IT services eliminate those surprises and reduce downtime dramatically.
Q: How do I switch to a managed IT services provider?
Switching is straightforward and designed to be non-disruptive. You and Lanmark agree on a start date. We audit your current environment, document your applications and data, and create a migration plan. We then install our monitoring and management tools, migrate your backups and security configurations, and train your staff on how to engage our helpdesk. Most migrations are completed within 2-4 weeks. We handle the technical work; your business continues as normal.
Q: What should I look for in a managed IT services provider in London?
Look for a provider with demonstrable expertise in your industry, clear SLAs (service level agreements) for response and resolution times, local support or a UK helpdesk, relevant security certifications, and references from similar businesses. Check whether the provider employs their own engineers (rather than outsourcing) and whether they hold advanced Microsoft, Cisco, or other vendor certifications. Ask about their security monitoring and threat response capability. Finally, ensure pricing is transparent and fixed, with no hidden per-incident charges. Lanmark is built around exactly this model.
Q: Do managed IT services include cybersecurity?
Managed IT services always include a security baseline: antivirus, firewalls, email filtering, patching, and best practice configuration. However, advanced threat monitoring and incident response (MDR/SOC services) is usually optional. Lanmark includes standard security in all managed IT services, and offers 24/7 Managed Detection and Response as an add-on for businesses with higher security requirements or regulatory obligations.
