1. What Outsourced IT Support Actually Means
Outsourced IT support means handing your technology management to an external company — a managed service provider (MSP) — instead of hiring an in-house IT person or team. The MSP becomes your IT department.
At a minimum, this covers helpdesk support (someone to call when things break), but most modern MSPs provide proactive management: device setup, security configuration, Microsoft 365 or Google Workspace administration, monitoring, patching, backup, and user onboarding/offboarding.
The key difference from the old “IT guy you call when something breaks” model is proactivity. An MSP monitors your systems, patches your devices, manages your security, and prevents problems — rather than just reacting to them after they've already cost you time and money.
2. In-House vs Outsourced: The Real Comparison
| In-House IT Hire | Outsourced MSP | |
|---|---|---|
| Annual cost (approx.) | £40,000–£55,000+ (salary, NI, pension, training, tools) | £6,000–£36,000 (based on 5–20 users) |
| Breadth of skills | One person's knowledge | Team of specialists (helpdesk, security, cloud, automation) |
| Availability | 9–5 minus holidays and sick days | Extended hours, always covered |
| Holiday / sickness | You're on your own | Team-based — no single point of failure |
| Scalability | Hire again | Scales with your headcount |
| Security expertise | Generalist at best | Dedicated security configuration and monitoring |
| Commitment | Employment contract | Rolling monthly — leave anytime |
| Recruitment risk | Takes months, might not work out | Immediate start, no recruitment |
The calculation is straightforward for most businesses with under 50 staff: an MSP gives you a whole team — helpdesk, security, cloud, and automation expertise — for less than the cost of one employee. The only scenario where in-house makes more sense is when you have specific, highly specialised needs that require someone full-time on-site.
3. The Three Service Models
Break-fix (pay as you go)
You call when something breaks. They fix it. You get a bill. No monitoring, no prevention, no proactive management. This was the standard 15 years ago. It's now the worst option for most businesses — you're paying for downtime, not prevention.
Avoid unless your IT needs are genuinely minimal.
Fully managed (MSP)
The MSP handles everything: helpdesk, devices, security, cloud, monitoring, onboarding, and backup. You pay a predictable monthly fee per user. They're proactive — monitoring your systems, patching your devices, and preventing problems before they happen.
Best for businesses with 5–50 staff who don't have (or want) an in-house IT person.
Co-managed
You have an internal IT person or team, and the MSP fills the gaps — overflow support, specialist cybersecurity, cloud projects, and holiday/sickness cover. The MSP and your internal team work side by side.
Best for businesses that have an IT person but need backup and specialist skills they don't have in-house.
4. What Should Be Included
Not all MSPs include the same things. At a minimum, a fully managed service should cover:
- ✓IT helpdesk — Phone, email, or chat with documented response time SLAs
- ✓Device management — Setup, encryption, patching, and lifecycle management for all devices
- ✓Microsoft 365 / Google Workspace admin — User accounts, email, licensing, and configuration
- ✓Cybersecurity basics — MFA, Conditional Access, anti-phishing, email authentication, endpoint protection
- ✓User onboarding & offboarding — New starters configured, leavers securely removed
- ✓Monitoring & patching — Proactive monitoring and automated security updates
- ✓Backup — Independent backup with tested restores — not just sync
If a provider doesn't include security as standard, or charges extra for “basic” things like MFA setup or patching, that's a red flag. These aren't extras — they're the baseline.
5. How to Evaluate a Provider
Questions to ask before signing with any MSP:
What's your average response time? (Get a number, not "fast".)
What's included in the monthly fee vs what costs extra?
Do you require a long-term contract, or is it rolling monthly?
How do you handle onboarding new staff and offboarding leavers?
What cybersecurity tools do you use and are they included?
How do you handle backup and disaster recovery?
Can I see an example of your monthly reporting?
What happens if we want to leave — how do you handle the transition?
Do we retain admin access and ownership of all our accounts?
How many clients does each support engineer handle?
6. Red Flags to Watch For
- ✗
Long-term contracts (12–36 months) with early exit penalties — a confident provider doesn't need to lock you in
- ✗
Security charged as an "add-on" — MFA, patching, and email authentication should be standard
- ✗
No transparency on response times — if they can't tell you their average, they don't track it
- ✗
They don't give you admin access to your own accounts — your accounts, your data, your admin rights
- ✗
No documented offboarding process — if you can't leave cleanly, they're relying on friction to keep you
- ✗
"Unlimited support" with no defined scope — everything has limits, and honest providers say so
- ✗
No proactive monitoring — if they only react when you call, you're paying for break-fix with a monthly label
7. The Switching Process
Switching IT providers feels daunting, but a competent MSP handles the entire transition. Here's what a clean handover looks like:
Credential handover and account audit. We get admin access to your Microsoft 365 tenant, domain registrar, and any other platforms. We audit what's configured and what's missing.
Security hardening. We fix immediate gaps — MFA, email authentication, Conditional Access, and endpoint protection. These protect you during the transition.
Device enrolment and configuration. We enrol devices into Intune, set up compliance policies, and configure monitoring. Your team keeps working throughout.
Helpdesk cutover. Your team starts using our helpdesk for support. We document your environment, confirm backup is in place, and complete staff onboarding.
The goal is zero downtime and zero disruption. Your team shouldn't even notice the switch happened — except that support suddenly got faster.
Frequently Asked Questions
For a UK small business with 5–30 staff, fully managed IT support typically ranges from £50–£150 per user per month depending on the scope. This usually covers helpdesk, device management, Microsoft 365 administration, cybersecurity, and monitoring. Pricing varies by provider and level of service — always compare what's included, not just the headline price.
Outsourced IT replaces your entire IT function — the provider handles everything. Co-managed IT supplements an existing internal IT person or team, providing overflow support, specialist skills (cybersecurity, cloud), and holiday/sickness cover. Co-managed is ideal when you have someone in-house but need backup.
Absolutely. Most IT support is delivered remotely — helpdesk, device management, cybersecurity, cloud administration, and monitoring don't require on-site presence. For occasional hands-on work (hardware, office moves), many providers have regional partners or travel to you.
A well-managed transition typically takes 5–10 business days. This includes credential handover, account audit, security configuration, device enrolment, and staff communication. A good provider handles the entire transition with zero downtime.
No. You retain full ownership of all accounts, data, domains, and infrastructure. A reputable MSP provides full transparency — admin access to all systems, documentation of all configurations, and no vendor lock-in. If you leave, everything stays yours.
