In-House vs Outsourced IT: UK Cost Analysis 2026
UK SMEs face a stark choice in 2026: hire in-house IT staff or outsource to an MSP. Here's what each option actually costs — and when to switch.
TL;DR: For most UK businesses under 75 employees, outsourced IT support costs significantly less than a single in-house hire — often £9,600–£24,000 per year versus £42,000–£49,000 — and delivers broader expertise. In-house hiring only becomes financially comparable at 75–100 staff.
Hiring your first IT person feels like the responsible move. You have 20 employees, Microsoft 365 licences to manage, the occasional ransomware scare, and a growing sense that relying on a tech-savvy colleague to reset passwords is not a strategy. The question is whether that hire will actually solve the problem — or simply create a new, more expensive one.
The outsourced IT support cost UK market has matured considerably. Managed Service Providers (MSPs) now offer per-user pricing that makes direct comparison with employment costs straightforward. Yet many SME owners still default to hiring because it feels more controllable. This guide puts both options on the same spreadsheet, identifies the break-even point, and gives you a framework for making the call with confidence — whether you run a 15-person professional services firm or a 60-person manufacturer pushing toward your next growth phase.
In-House vs Outsourced IT UK: What Does Each Option Actually Cost?
The median salary for a UK IT Support Engineer is approximately £35,000 per year. That figure, however, is only the starting point. Once you add employer National Insurance contributions, pension auto-enrolment, recruitment fees, training budget, and management overhead, the total employment cost rises to 20–40% above gross salary — putting the real annual cost of a £35,000 hire at between £42,000 and £49,000.
Outsourced managed IT support, by contrast, is typically priced at £40–£100 per user per month for a fully managed service in 2026. For a 20-person business, that translates to £9,600–£24,000 per year — a fraction of the employment cost, and without the single-point-of-failure risk that comes with a one-person IT department.
| Business size | Annual outsourced IT cost (£40–£100/user/month) | Real cost of one IT hire (£35k salary + on-costs) |
|---|---|---|
| 10 users | £4,800 – £12,000 | £42,000 – £49,000 |
| 20 users | £9,600 – £24,000 | £42,000 – £49,000 |
| 50 users | £24,000 – £60,000 | £42,000 – £49,000 |
| 75–100 users | £36,000 – £120,000 | £84,000 – £98,000 (two hires) |
The break-even point — where building an in-house team becomes financially comparable to outsourcing — typically sits at 75–100 employees. Below that threshold, the numbers almost always favour an MSP.
What Are the Hidden Costs of In-House IT That Most Budgets Miss?
Salary and National Insurance are visible line items. The costs that erode the case for in-house IT are the ones that rarely appear in a hiring proposal.
Coverage gaps. A single IT employee is, by definition, a single point of failure. When they are ill, on annual leave, or — most expensively — working their notice period, your business has zero dedicated IT cover. Recruiting a replacement typically takes eight to twelve weeks and costs a further 15–20% of annual salary in agency fees.
Downtime exposure. IT downtime costs a UK small business an estimated £3,000–£6,000 per hour. A single unresolved outage during a coverage gap can dwarf months of MSP fees. This is not a theoretical risk; it is the most common trigger for SMEs switching from in-house to outsourced support.
Skills breadth. One person cannot credibly cover cybersecurity, cloud infrastructure, networking, end-user support, and compliance simultaneously. Continuous training to keep pace with evolving threats adds further cost — and even with training, a solo technician will always have blind spots.
Tooling. Professional-grade remote monitoring, endpoint detection, and patch management platforms carry their own licensing costs. MSPs spread these across their entire client base; you absorb them entirely.
Pro tip: Before comparing MSP quotes with a salary figure, add recruitment fees, employer NI, pension, training allowance, and an estimate of downtime risk to your in-house cost. The gap widens considerably.
Licensing complexity. Managing Microsoft 365 or Google Workspace at scale — licence assignments, security policies, conditional access, and compliance settings — requires specialist knowledge that a generalist support technician may lack. Errors here carry regulatory as well as operational consequences.
When Should You NOT Outsource Your IT Support?
Outsourcing is not the right answer for every business, and an honest cost analysis has to say so.
If your organisation has 100 or more employees and genuinely complex, bespoke infrastructure — on-premises servers, custom-built line-of-business applications, or regulated data environments requiring dedicated on-site presence — a blended model (in-house IT manager plus specialist MSP for specific functions) often makes more sense than full outsourcing. At that scale, the per-user MSP cost can approach or exceed the cost of a small internal team.
Similarly, if your business operates in a sector with strict data residency requirements and your legal team has determined that third-party access to systems creates unacceptable risk, in-house may be the only compliant option. That is a genuine constraint, not a reason to dismiss outsourcing categorically.
The case for keeping IT in-house is also stronger when your competitive advantage is directly tied to proprietary technology that requires constant, intimate internal knowledge — think software product companies or businesses with significant R&D operations.
For the majority of UK SMBs, however, none of these conditions apply. The UK Government’s 2025 Cyber Security Skills report found that around 49% of UK businesses have a basic technical cyber security skills gap. Outsourcing to a specialist MSP directly mitigates that risk by providing immediate access to a team with diverse specialisms — cybersecurity, cloud, networking — that is almost impossible to replicate with a small in-house hire.
Pro tip: Ask any MSP you are evaluating these five questions before signing: What is your guaranteed response time for critical outages? How do you handle out-of-hours incidents? What does your onboarding process look like? How do you manage Microsoft 365 or Google Workspace licence changes? And — crucially — what happens to our data if we terminate the contract?
If a provider cannot answer all five clearly and in writing, move on.
For businesses that want the coverage and expertise of an MSP without sacrificing visibility, Zorinto’s managed IT support for Microsoft 365 and Google Workspace is built specifically for UK SMBs and scale-ups — with transparent per-user pricing and no opaque contract terms.
What This Means for Managed IT in 2026
The economics of outsourced IT support have not shifted dramatically in the past two years, but the risk calculus has. Cyber threats targeting SMBs are more frequent and more sophisticated, Microsoft 365 and Google Workspace environments are carrying more sensitive data than ever, and the IT skills gap shows no sign of closing, with 84% of businesses reporting difficulty sourcing the talent they need.
For growth-stage businesses across the Thames Valley — whether you are scaling a professional services firm, a logistics operation, or need specialist website development in Maidenhead alongside your broader IT stack — the 2026 environment rewards businesses that treat IT as a managed service rather than a staffing problem. Per-user MSP pricing scales with your headcount, so your IT costs grow proportionally rather than in the large, lumpy increments that come with each new hire.
The break-even point at 75–100 employees gives most SMBs a clear runway: outsource now, build a hybrid model when the numbers justify it.
Key Takeaways
- The real annual cost of a £35,000 IT hire is £42,000–£49,000 once employer on-costs are included — before tooling, training, or recruitment replacement costs.
- Outsourced managed IT support for a 20-person UK business typically costs £9,600–£24,000 per year, making it significantly cheaper than a single in-house hire at that scale.
- The financial break-even point between in-house and outsourced IT sits at approximately 75–100 employees for most UK SMBs.
- A solo in-house IT employee creates a single point of failure; IT downtime costs UK small businesses an estimated £3,000–£6,000 per hour, making coverage gaps a material financial risk.
- Before choosing a provider, ask explicitly about response time guarantees, out-of-hours cover, Microsoft 365 or Google Workspace management capability, and contract exit terms.
Conclusion
The numbers are clear for most UK businesses under 75 employees: outsourcing IT support costs less, covers more, and removes the single-point-of-failure risk that comes with a one-person internal team. The decision becomes more nuanced as you scale, but the default position for an SMB in 2026 should be to outsource first and revisit in-house hiring when your headcount genuinely justifies it.
