A managed service provider (MSP) is an outsourced IT team that runs your technology for a fixed monthly fee — usually £40–£80 per user per month in 2026. They handle helpdesk, security, Microsoft 365, backup and updates, and get paid whether anything breaks or not. The point is fewer incidents, not faster firefighting.
The short version
A managed service provider is a company that takes over the day-to-day running of your IT. Instead of hiring an in-house IT manager or ringing a technician every time something breaks, you pay a monthly subscription and they look after everything — helpdesk, Microsoft 365, security, backup, new starters, leavers, patching, the lot.
The clue is in the word "managed". An MSP doesn't only fix things when you ask. They watch your estate all the time, apply updates before exploits are public, and tell you when something's wearing out. If they're doing their job properly, you hear from them less — not more.
What a modern UK MSP actually does
The scope varies, but a typical 2026 small-business contract covers:
- Helpdesk — unlimited remote support during office hours, usually 8:30–17:30, with out-of-hours cover for priority incidents.
- Endpoint management — Intune or equivalent, enforcing device encryption, screen lock and security baselines.
- Patching — Windows, macOS and third-party apps, every month, tested and reported.
- Security — endpoint detection and response (Defender for Business, SentinelOne), MFA, phishing defence, user training.
- Microsoft 365 management — tenant configuration, new starters and leavers, licence optimisation.
- Backup — SaaS backup for Microsoft 365, plus anything still on-prem.
- Reporting — a monthly summary in plain English, and a quarterly strategic review at higher tiers.

MSP vs break-fix vs in-house
Three models dominate UK SME IT:
- Break-fix — £75–£150 per hour when you call. Cheapest on paper, most expensive when something goes wrong. No prevention.
- In-house IT manager — £38,000–£55,000 a year fully loaded, plus holidays. Great for mid-market. Usually a luxury under 25 staff.
- MSP — a monthly subscription that sits between the two. Works well for 5–50 staff, and often stays the right answer well past that.
The honest comparison is this: one in-house generalist can't cover helpdesk, security operations, Microsoft 365, networking and vendor management without gaps. An MSP fields a whole team and spreads the cost across its client base.
How MSPs charge
Most UK MSPs charge per user per month. Some charge per device, some fixed-fee. Prices in 2026 cluster around:
- £25–£40 per user per month — basic remote support and patching.
- £40–£80 per user per month — proactive managed, the common SME tier.
- £80–£150 per user per month — premium with onsite days and a vCIO.
Microsoft 365 licences are almost always a separate line — around £22 per user per month for Business Premium, paid either to Microsoft directly or reinvoiced by the MSP. If a quote bundles everything into one opaque number, ask for a breakdown.
How to spot a good one
A few tests that separate decent MSPs from sales-led ones:
- Published pricing — good MSPs quote publicly. Hidden prices usually mean they're making it up per caller.
- Written SLA — actual minutes and hours tied to ticket priority, not "we aim to respond promptly".
- 30-day notice — 36-month contracts suit the provider, not you. The confidence to go month-to-month says a lot.
- Named engineers — you should know who picks up the phone. A faceless ticket queue is a red flag.
- Cyber Essentials readiness — from 27 April 2026, the v3.3 scheme auto-fails anyone who hasn't enabled MFA on cloud services that offer it. Your MSP should be building contracts around that.
- Plain-English reporting — one page a month you'd actually read, not a 40-page PDF.
When an MSP is the wrong answer
MSPs aren't universal. If you're a three-person business with two laptops, a Microsoft 365 plan and no server, you probably don't need a contract — a block of ad-hoc hours will do. If you're a 200-person business with regulated workloads, a dedicated in-house lead with one or two analysts plus a specialist security retainer often beats a pure MSP model. The sweet spot for outsourced managed IT sits between roughly 8 and 100 users.
Where the name comes from
"Managed service provider" started in US telecoms in the 1990s. UK small-business IT adopted it in the 2000s as a reaction against break-fix — charging monthly aligned incentives, because the provider stopped earning every time something went wrong. By 2026 the label is so common that most buyers still just Google "IT support" and end up at MSPs anyway. Microsoft's own Microsoft 365 Business Premium guidance assumes an MSP will be running it for most small firms.
FAQs
Is an MSP the same as IT support?
Near enough. MSP is the industry name; IT support is what most small businesses Google. A modern MSP provides IT support plus proactive management — patching, monitoring, security, backup — for a monthly fee.
How is an MSP different from break-fix?
Break-fix means you only pay when something breaks, usually at £75–£150 per hour. MSPs charge monthly whether you call or not, and are paid to stop problems happening in the first place. Incentives point the right way.
Do I need an MSP at 10 employees?
Most businesses cross the threshold between five and fifteen staff. Below that, a single technical person can usually cope. Above ten, the admin overhead — new starters, leavers, Microsoft 365, security — tends to justify outsourcing.
Do MSPs resell Microsoft licences?
Most do. You can also buy direct from Microsoft and pay the MSP only for management — either is fine. Just make sure the bill split is clear.
Can I keep my existing IT person and still use an MSP?
Yes — the co-managed model is common. The MSP takes night-and-weekend cover, security monitoring and vendor escalation; your in-house person handles the everyday. It works well up to about 75 staff.
