Managed IT Services vs IT Outsourcing: Pricing, SLAs and Coverage Explained 2026
Managed IT services are proactive cover — monitoring, patching and security for a fixed monthly fee with SLAs that prevent tickets — while IT outsourcing is flexible capacity that reacts to tickets; most UK 10–100-person businesses should buy managed in 2026/27 and add outsourced capacity only for projects. Prevent vs react is the buying question.

inLanguage: en-GB · 2026/27 pricing & SLA stamped
- Managed IT = fixed fee per user/device, 24/7 monitoring, patching, SOC, SLAs — prevents tickets. Outsourcing = pay per ticket/project, reactive.
- Pricing 2026/27 UK: managed £50–£150/user/month (scale with seats); break-fix/outsource £75–£150/hour or £25–£45/user without cover; all-in true-cost lens is 1.55× salary for any in-house IT hire.
- SLAs are the contract — response and resolution by severity, with credits if missed; without an SLA you have a queue, not a service.
- Coverage: managed includes endpoint, patch, backup/DR, identity/MFA and baseline security; projects (migrations, rollouts) sit as scoped outsourcing beside it.
- ZI lens: Layers 2–4 compound even in IT — fewer tickets via automation, owned tooling that retires SaaS, and a team that keeps the stack current rather than standing still.

What is the difference — managed vs outsourcing vs in-house?
Answer first: Managed prevents the ticket; outsourcing handles the ticket you raise; in-house owns the queue but also the single point of failure and the 1.55× true cost.
Managed IT services: a proactive service for a fixed monthly fee (per user/device). Includes monitoring, patching, endpoint protection, backup/DR checks, identity/MFA, and a SOC baseline — with contractual SLAs and reporting. Goal: fewer tickets next month than last.
IT outsourcing: flexible capacity — a helpdesk, engineer or project pod you call on — billed per ticket, per hour (£75–£150/hour UK 2026/27) or per project. No standing prevention mandate unless you contract it.
In-house IT: one or two hires who know your stack — responsive, but coverage is bounded by diaries and holidays, and true cost is ~1.55× salary (UK employer costs ~33% + indirect ~22% — recruitment, HR, manager supervision, equipment/software, onboarding, attrition buffer per BUSINESS_CONTEXT.md §A5).
Third-party context: CompTIA IT Industry Outlook 2024 (Dec 2023) documented persistent skills gaps driving managed adoption, and Gartner (6 Feb 2024) forecast worldwide IT spending to grow 6.8% in 2024 — both pressures that push small businesses from break-fix toward contractual cover.
Positioning: ZI’s IT outsourcing discipline is managed and SLA-led where it is sold as workforce; break-fix outsourcing sits as a project adjunct. See the pillar IT Outsourcing and the buying comparison in-house vs outsourced.
What does each cost in 2026/27 — per user, per hour, per outcome?
Answer first: Compare per user per year with SLAs, not per hour without them — managed £600–£1,800/user/year wins on total cost once downtime and manager hours are counted.
| Model (2026/27 UK) | Fee basis | Typical band | SLA | Delta vs managed (50 users) |
|---|---|---|---|---|
| In-house IT (1 hire) | Salary × 1.55 | £45k base → ~£69.8k true; 2 hires → ~£139.5k | None — diary | +~£9k to +~£79k vs managed 50 users; no cover |
| Managed IT services | £/user/month | £50–£150/user/mo → £30k–£90k/yr for 50 users | Yes — contracted | Baseline — prevention included |
| Outsourced break-fix | £/hour or ticket | £75–£150/hr; £25–£45/user/mo without SLA | Queue, not SLA | Unpredictable — spikes with incidents |
| ZI managed IT ops pod (Model 01) | FTE managed + SLA | 30–40% below 1.55× true cost; supervisor + QA | Yes — daily logs + review | Like-for-like 30–40% saving on headcount; tool collapse extra |
2026/27 UK illustrative for 50 users; scale bands narrow with seat count. The 1.55× rule is the universal comparator — percentages travel, local payroll taxes do not. See pricing calculator logic (now 30–40% below true cost, not the old 70–80% spec).
First-party ZI number: in non-IT domains ZI already tracks Layer 3 tool collapse (£40–£80/month email verification at <2% bounce; outreach platform £1,000–£2,400/year retired; CRM stack £800–£2,000/month reference). In IT the same lever is endpoint/backup/identity consolidation — fewer subscriptions, one managed pane.

What do SLAs actually promise — response, resolution and credits?
Answer first: An SLA is a contractual time to respond and to resolve by severity, with a credit if it is missed — without that, you have a best-effort queue.
Read any IT proposal through the SLA table first, the price second. Severities are typically P1 (service down) → P4 (cosmetic/request). Each has a response target (first human) and a resolution/restoration target, with a service credit (e.g., 5–25% of monthly fee) if missed — and a clear exclusion list.
| Severity | Example | Response SLA | Resolution target | Delta vs no-SLA queue |
|---|---|---|---|---|
| P1 — Critical | Mail/identity down, site down | 15–30 min | 4 hrs restoration | Contracted vs “asap” |
| P2 — High | Team/service degraded | 1 hr | 8 hrs | Measured, reported |
| P3 — Normal | Single-user issue, request | 4 hrs (business) | 1–2 business days | Scheduled, not lost |
| P4 — Low | Cosmetic, how-to | Next business day | Best effort / backlog | Prioritised transparently |
Illustrative managed SLA — verify your provider’s numbers and credit mechanism in writing. Break-fix outsourcing rarely commits beyond queue order.
What is covered — and what is always a project?
Answer first: Managed covers the standing risk surface — endpoint, patch, backup verification, identity/MFA and baseline monitoring — projects are the net-new changes: migrations, rollouts, and builds.
Typically in managed (included): endpoint protection and patching, backup verification and restore tests, identity/MFA and joiners/leavers, asset and licence hygiene, 24/7 monitoring and first-line help, and monthly reporting against ticket volume and SLA. Typically a scoped project (beside managed): Microsoft 365 / Google Workspace migration, device rollout/refresh, network/ Wi-Fi redesign, security uplift (e.g., SOC hardening, conditional access), data migration or CRM/ERP-adjacent work. ZI’s IT-adjacent workforce pods (Model 01) handle ops and ticket throughput with supervisor QA; dedicated AI engineering for IT projects (Model 03) is your IP with a ZI tech lead behind it.
How do you choose for a 10–100-person business?
Answer first: Under ~10 users: break-fix can be rational; 10–100: buy managed as the floor, then add outsourced project hours beside it — never the reverse.
The decision is coverage per pound. Below ~10 users the incident rate sometimes makes break-fix cheaper on paper — until a single outage erases the saving. At 10–100, fixed-fee managed wins because it prevents the tickets that break-fix bills you for, and because a single in-house hire cannot deliver 24/7 cover or breadth (identity + endpoint + backup + user support) without becoming the bottleneck. Run the pricing calc at 1.55× vs 30–40% below, then add the risk line: one P1 outage at month-end often costs more than the managed delta for the quarter.
Buying checklist: written SLA with credits, named tooling you can audit, monthly ticket/SLA report, joiners/leavers SLA, and a clear project rate beside the managed fee. Data posture still governs: NDA + DPA before day one, work inside your systems so data never leaves your control.
Where does the AI-enabled workforce angle fit in IT?
Answer first: The same four layers — Layer 1 cost per role, Layer 2 fewer tickets via automation and prompts, Layer 3 owned tooling that retires SaaS, Layer 4 guaranteed evolution — are the reason IT cover compounds instead of just renewing.
Ticket deflection is the Layer 2 win: prompt-led KB answers, auto-triage and routing with human sign-off, and small utilities that remove per-seat or per-ticket tooling (Layer 3). The pod’s 90-day review is on tickets per 100 users and mean time to resolve, baselined from your helpdesk logs or opening-weeks measurement and labelled honestly if estimated. As with every ZI engagement, the improvement method is the same — list every manual operational activity with stakeholders, prioritise what unblocks the most downstream work, then ship prompts/workflows/small builds in that order, never too many areas at once.
Frequently asked questions
Is managed IT the same as outsourcing?
No — managed is proactive prevention with SLAs for a fixed fee; outsourcing is reactive capacity per ticket/project. Buy managed as the floor, add project hours beside it.
What should an SLA include?
Response and resolution by severity, a service credit if missed, and written exclusions — reported monthly against tickets per 100 users and MTTR.
Can we keep one in-house IT person and add managed?
Yes — hybrid is common at 20–100 staff. In-house keeps context; managed brings 24/7 cover and breadth (identity, endpoint, backup) plus the SLA.
Who owns tooling and data?
Your data is always your IP under NDA + DPA. New builds under Models 02/03 are your IP; managed service delivery under Model 01 is ZI IP as a service.
How fast can a pod start?
10–14 days from brief sign-off, process-led via a 6-stage hire filter. SLA coverage starts once monitoring and documentation baselines are set.
