A managed service provider (MSP) is a company that delivers ongoing IT support, monitoring, maintenance and management for a business, typically for a fixed monthly fee. Rather than waiting for something to break and billing for the time to fix it, an MSP proactively monitors systems, applies updates, manages security and resolves issues, often before the business notices a problem at all.
How a managed service provider works
An MSP typically deploys monitoring tools across a client's devices, servers and cloud services, including Microsoft 365, to detect issues automatically. A help desk handles day-to-day support requests from staff, while a wider team manages strategic IT planning, security and infrastructure. Most MSP agreements are billed per user or per device per month, covering a defined scope of services rather than charging separately for every piece of work.
How UK SMEs use a managed service provider
- A 40-person business with no internal IT staff outsources its entire IT function to an MSP, covering everything from helpdesk support to cyber security and Microsoft 365 management.
- A growing company keeps a small internal IT team for day-to-day support but uses an MSP for specialist cyber security monitoring and out-of-hours cover.
- A business switches from a break-fix IT supplier to an MSP after repeated unplanned downtime, valuing the proactive monitoring that catches issues before they cause an outage.
- A company uses its MSP to manage Microsoft 365 licensing, device security and backup as a single bundled service rather than coordinating multiple separate suppliers.

Frequently asked questions
What is the difference between an MSP and a break-fix IT company?
A break-fix provider is called when something goes wrong and bills for the time spent fixing it. An MSP provides ongoing, proactive monitoring and maintenance for a fixed monthly fee, aiming to prevent issues before they cause downtime rather than waiting to be called after something fails.
Does using an MSP mean a business no longer needs any internal IT staff?
Not necessarily. Many businesses use an MSP to cover the full IT function, particularly SMEs without the scale for a dedicated internal team. Larger organisations often use an MSP alongside a smaller internal IT team, with the MSP handling specific areas such as cyber security, infrastructure or out-of-hours support.
What should be included in an MSP service level agreement?
A typical MSP service level agreement defines response times for different issue priorities, the scope of services covered, escalation procedures and reporting commitments. It should be specific enough that both parties understand what is covered, rather than vague language about general support.
