Outsourced IT Support Cost UK: 2026 SMB Guide

TL;DR: For most UK SMBs under 100 employees, outsourced IT support costs £30–£80 per user per month — often less than half the fully loaded cost of a single in-house hire. Unless you have complex, bespoke infrastructure, outsourcing is almost certainly the more cost-effective and lower-risk choice.

Hiring the wrong IT model is one of the quieter ways a growing business bleeds money. A mid-level IT manager costs around £55,230 in base salary alone, and that figure climbs to between £43,000 and £70,000 once you factor in National Insurance, pension contributions, training, and software licences. Meanwhile, 50% of UK businesses experienced a cyber breach or attack in the past year, meaning the cost of getting IT wrong is no longer just a productivity question — it is a business continuity one. If you are an operations director or founder actively weighing up outsourced IT support costs in the UK, this guide gives you the numbers, the framework, and the right questions to ask before you sign anything.

How Much Does Outsourced IT Support Cost in the UK?

Outsourced IT support for UK SMBs is almost universally priced on a per-user, per-month basis. According to industry pricing data from Compare the Cloud, basic helpdesk-only packages run from £30 to £50 per user per month. A more comprehensive managed service — covering security monitoring, patch management, Microsoft 365 or Google Workspace administration, and data backup — typically sits between £50 and £80 per user per month. For a 50-person business on a mid-range contract at £50 per user, that is £30,000 per year in total. A single in-house IT technician at the same headcount would cost your business considerably more before they have answered a single support ticket.

What Does an In-House IT Hire Actually Cost You?

The sticker price on a job advert is not the real cost. The fully loaded cost of a UK employee is typically 1.25 to 1.5 times their base salary once you account for employer National Insurance contributions, auto-enrolment pension, paid leave, recruitment fees, and the software tools they need to do the job.

Apply that multiplier to IT roles specifically and the numbers become stark:

For a 75-person SME that needs genuine coverage — not just one person who is on holiday when the server goes down — basic in-house IT provision can exceed £180,000 per year once you account for more than one hire. A comparable outsourced service for the same headcount could cost around £85,500 annually, a saving of over £94,000 with broader specialist expertise included, according to analysis from Connection Technologies.

The single-hire problem is also a coverage problem. One person cannot monitor your network at 2 a.m., respond to a ransomware alert, and train a new starter on Microsoft 365 simultaneously. An MSP brings a bench of specialists for the same monthly fee.

Pro tip: Gartner research indicates businesses moving to a managed IT model can reduce total IT operational costs by up to 30%. Use that figure as a conservative floor when building your internal business case.

Is Outsourced IT Right for Your Business — or Should You Keep It In-House?

Outsourcing is not the right answer for every organisation. Here is an honest framework.

Outsourcing is almost certainly the right call if:

• You have fewer than 75–100 employees and no highly bespoke, on-premises infrastructure.
• Your current IT person is a generalist stretched across support, security, and strategy simultaneously.
• You have experienced downtime or a security incident in the past 12 months and have no formal incident response plan.
• You are scaling quickly and cannot predict headcount 18 months out.

Keeping IT in-house may make sense if:

• You operate in a heavily regulated sector (financial services, healthcare) with strict data residency requirements that demand dedicated on-site resource.
• You have a large, complex bespoke application that requires deep institutional knowledge to support.
• You already have a mature internal IT team and simply need supplementary cover for specific functions.

For the vast majority of UK SMBs running standard SaaS stacks — Microsoft 365, Google Workspace, cloud storage, and a handful of vertical applications — a well-chosen MSP will outperform a single in-house hire on cost, coverage, and security depth. Zorinto’s managed IT support for Microsoft 365 and Google Workspace is built specifically for this profile of business: UK SMBs and scale-ups that need enterprise-grade reliability without enterprise-grade headcount.

Pro tip: The break-even point for in-house IT versus outsourcing typically sits at 75–100 employees. Below that threshold, the maths almost always favour an MSP.

What Good Looks Like — and the Red Flags to Watch For

Not all managed service contracts are equal. Before you sign, scrutinise what is actually included.

A credible MSP contract should include:

• A UK-based helpdesk with defined response times (SLA) — for example, P1 critical issues resolved within four hours.
• Proactive monitoring and patch management, not just reactive break-fix support.
• Microsoft 365 or Google Workspace administration and licence management.
• Endpoint security (antivirus, device management) and data backup with tested recovery procedures.
• Clear escalation paths and a named account manager.

Red flags that should give you pause:

• No mention of security certifications such as Cyber Essentials Plus or ISO 27001.
• SLAs that define response time but not resolution time — a provider can “respond” in 15 minutes and take three days to fix the problem.
• Contracts that lock you in for 36 months with punitive exit clauses before you have seen their work.
• Vague pricing with add-on charges for things you would reasonably expect to be included, such as backup restoration or out-of-hours support.

Five questions to ask any MSP before you commit:

1. What are your SLA response and resolution times, by priority level?
2. Do you hold Cyber Essentials Plus or ISO 27001 certification?
3. Can you provide two or three references from UK businesses of similar size and sector?
4. What happens to our data and configurations if we choose to leave?
5. How do you handle out-of-hours incidents — dedicated staff or an on-call rota?

What This Means for Managed IT in 2026

The managed IT market in the UK is maturing rapidly. Pricing is becoming more transparent, SLAs are more standardised, and the quality gap between the best and worst providers is narrowing — which makes due diligence more important, not less. The businesses that will get the most value from outsourced IT in 2026 are those that treat their MSP as a strategic partner rather than a helpdesk ticket system: involving them in procurement decisions, cloud migrations, and security planning from the outset.

For growth-stage businesses across the Thames Valley — whether you are scaling a professional services firm, a tech-enabled retailer, or a company that also needs support with website development in Maidenhead — the practical question is not whether to outsource IT, but which provider has the depth to grow with you. Cyber threats are not becoming simpler, and the cost of a breach will always exceed the cost of prevention.

Key Takeaways

• A fully loaded in-house IT hire costs UK businesses £43,000–£82,000+ per year; outsourced IT support typically costs £30–£80 per user per month.
• For a 50-person business, a mid-range MSP contract at £50 per user per month totals £30,000 per year — often less than a single junior hire.
• The financial break-even point for in-house versus outsourced IT sits at roughly 75–100 employees; below that, outsourcing almost always wins on cost.
• A credible MSP contract must include proactive monitoring, patch management, endpoint security, data backup, and a UK-based helpdesk with defined SLAs.
• Always verify security certifications (Cyber Essentials Plus, ISO 27001), ask for client references, and scrutinise exit terms before signing any managed IT contract.

Conclusion

For most UK SMBs, the outsourced IT support cost question has a clear answer: a well-scoped MSP contract delivers more coverage, more security expertise, and a lower total cost than an equivalent in-house hire — particularly below the 100-employee mark. The decision comes down to choosing the right provider. If your business runs on Microsoft 365, Google Workspace, or a core SaaS stack and you want predictable monthly costs without the recruitment risk, it is worth getting a scoping conversation on the calendar. Zorinto offers IT support and management for UK SMBs running Microsoft 365 and Google Workspace — a practical starting point if you want to understand what a contract should include and what it should cost for your headcount.
