Managed IT services vs in-house support: how to choose
A cost, capability and risk framework for growing UK businesses reviewing IT support.
By the Telappliant team
Growing businesses hit a point where a single internal IT person can't cover breadth, depth and hours. The right answer is rarely all-or-nothing.
What in-house does well
- Deep knowledge of your business and its quirks
- On-site presence for hands-on issues
- Ownership of strategic projects and vendor relationships
What a managed IT partner adds
- 24/7 helpdesk with SLAs, not best-effort
- Access to specialists in security, networking, cloud and telephony
- Tooling for monitoring, patching, EDR and backup at scale
- Predictable per-user cost and clear reporting
The blended model most SMEs land on
One internal IT lead who owns strategy and vendor management, backed by a managed service provider handling day-to-day helpdesk, out-of-hours cover and specialist projects. You keep the institutional knowledge and buy the depth and hours you can't hire.
