IT Problems Slowing Your Business Down? — We Fix That

What is managed IT support?

Managed IT support is a contract where an external provider takes ownership of running, monitoring and maintaining your business IT. For a UK SME it replaces or extends an internal IT function — giving you a full team of engineers, a UK helpdesk and 24/7 monitoring at a predictable monthly cost instead of unplanned firefighting.

The day-to-day scope of a serious managed IT contract covers:

• IT helpdesk — phone, email and portal support from UK-based engineers, with documented response times by issue severity.
• Infrastructure monitoring — 24/7 automated monitoring of servers, network devices, firewalls and endpoints, remediated before users notice.
• Patch management — automated OS and application patching, with a 14-day target for critical vulnerabilities and monthly compliance reports.
• Microsoft 365 management — user provisioning, licence optimisation, security configuration and Teams administration.
• Backup and disaster recovery — automated daily backup of servers, Microsoft 365 data and cloud apps, with recovery procedures tested at least annually.
• Cybersecurity — endpoint protection, email security and firewall management built in, not sold as a separate add-on.

For the operational layer of this service, see our managed IT support and UK IT helpdesk pages.

What's the difference between managed IT and break-fix IT?

Break-fix IT is reactive: something breaks, you call an engineer, you pay for the time. Managed IT is proactive: your systems are monitored continuously, problems are fixed before they spread, and you pay a fixed monthly fee. For any business beyond roughly 10 staff, managed IT delivers better uptime at a more predictable cost.

See how the co-managed model fits alongside an in-house IT manager on our co-managed IT page.

Why do UK SMEs need managed IT support?

UK SMEs need managed IT because the threat and uptime burden has outgrown what one or two internal hires can cover. The UK government reports that 43% of UK businesses experienced a cybersecurity breach or attack in the past 12 months (DSIT Cyber Security Breaches Survey 2025) — continuous monitoring and patching is the practical defence.

That figure comes from the UK government's own research; read the Cyber Security Breaches Survey 2025. The National Cyber Security Centre sets out why timely patching and monitored endpoints are among the highest-impact controls a smaller business can put in place.

Managed IT closes the gap with:

• Continuous patching and monitoring that a stretched internal hire cannot maintain alone.
• A documented, supported environment instead of undocumented tribal knowledge.
• Built-in security controls aligned to recognised UK guidance.
• For deeper protection, our complete business IT protection and business continuity services extend cover to recovery and resilience.

How does AMVIA onboard a new managed IT client?

Switching provider follows a structured four-week programme designed for continuity. AMVIA audits and documents your full estate, deploys monitoring across every device, establishes a security baseline, then moves your team onto the helpdesk — with monthly reporting from day one. No disruptive "rip and replace".

• Week 1–2 — Discovery: full audit of servers, devices, licences and cloud services, producing a documented IT asset register and network diagram.
• Week 2–3 — Tooling: Remote Monitoring and Management (RMM) agents deployed and monitoring policies configured across the estate.
• Week 3–4 — Security baseline: posture assessed against security compliance requirements, with gap remediation started.
• Week 4+ — Business as usual: your team uses the AMVIA helpdesk, and monthly reporting on tickets, system health and patch compliance begins.

If you run on-premises or hybrid infrastructure, our IT infrastructure management and cloud migration services handle the heavier projects discovery uncovers.

How much does managed IT support cost?

Managed IT support for UK SMEs typically costs £25–65 per user per month for fully managed IT, rising with scope. As a guide, basic helpdesk-and-monitoring cover sits at the lower end, while packages adding Microsoft 365 management, backup and SOC-grade security sit at the top. Pricing is fixed and per-user, with no surprise call-out charges.

Compare this to building the same capability in-house. A single in-house IT hire costs £40,000+ before overheads; a mid-level IT engineer in the UK costs £35,000–£55,000 in salary alone, plus employer NI, pension, holiday cover, equipment and recruitment. A team of three — the minimum for adequate coverage — costs well over £150,000 per year. Managed IT delivers equivalent or better capability for a fraction of that for most UK SMEs.

What service levels should you expect?

You should expect contractual response times tied to issue severity, not vague best-effort promises. AMVIA's SLA defines four priority tiers, with response measured as an engineer actively investigating — not an automated acknowledgement. Critical incidents are covered 24/7/365, and breaches of the commitment carry defined consequences.

• Priority 1 (Critical): complete outage or security incident — one-hour response, 24/7/365.
• Priority 2 (High): significant degradation affecting multiple users — two-hour response in business hours.
• Priority 3 (Medium): single-user issue — four-hour response in business hours.
• Priority 4 (Low): minor request or change — next business day.
