If you’re weighing up whether to hire your own IT person or bring in an outsourced provider, you’re really deciding how your business gets support, security and expertise for the years ahead, not just who answers the phone when something breaks. This guide compares both models directly on cost, cover, expertise and risk, so you can work out which fits your business now and which might make more sense later.
What In-House IT Support Actually Means
In-house IT support means employing one or more IT staff directly, on your payroll, working from your premises or reporting into your business day to day. They know your systems intimately because they built or maintain them, and they’re physically available when something needs a hands-on fix.
- A dedicated person (or small team) who knows your systems, users and history in detail
- Immediate, in-person availability during working hours
- Full control over priorities, without needing to raise a ticket with an external provider
- Coverage limited to that person’s own skills, working hours and availability
- A fixed cost that rises with salary reviews, but doesn’t scale down in quiet periods
The strength of in-house IT is depth of institutional knowledge. The weakness is that it depends on one or two people. If your only IT hire is off sick, on leave, or leaves the business, cover can disappear overnight unless you’ve planned for it.
What Outsourced IT Support Actually Means
Outsourced IT support means handing day-to-day IT support and management to an external provider for a monthly fee, rather than employing someone directly. You still own your systems and make the decisions. The provider supplies the people, tools and monitoring that keep everything running.
- Access to a team of specialists covering networking, security, cloud and more, rather than one generalist
- 24/7 monitoring and helpdesk cover as standard with most managed IT support providers
- A predictable monthly fee that’s easier to budget for than a variable in-house overhead
- Scales up or down as headcount changes, without a recruitment process
- Less day-to-day, in-person familiarity than someone sitting in your office every day
The strength of outsourced IT is breadth: you get a bench of specialists and continuous cover, not one person’s knowledge and availability. If your business fits this model, our outsourced IT support service is built around exactly this kind of cover.
In-House vs Outsourced IT Support: Side-by-Side Comparison
Here’s how the two models compare directly against the factors that usually decide this for UK businesses.
| Factor | In-House IT Support | Outsourced IT Support |
|---|---|---|
| Typical cost | Salary plus employer National Insurance, pension contributions, recruitment and training, usually well above the headline salary figure | Fixed monthly fee per user, typically £40 to £100 per user per month in 2026 depending on cover |
| Breadth of expertise | Limited to what that individual (or small team) knows | Access to a wider team covering networking, cloud, security and more |
| Availability | Working hours only, unless you pay for additional out-of-hours cover | Often 24/7 monitoring and helpdesk access as standard |
| Key-person risk | High. Holiday, illness or resignation can leave you without cover | Low. The provider is responsible for staffing continuity |
| Scalability | Requires recruitment to grow, and redundancy costs to shrink | Scales with your user count, typically without a recruitment cycle |
| Familiarity with your business | Very high, built up through daily, in-person presence | Good, built through onboarding and account management, but less immediate than someone on-site every day |
| Security tooling and monitoring | Depends entirely on what your in-house team can justify buying and maintaining | Usually includes enterprise-grade monitoring and security tools as part of the service |
The True Cost of an In-House Hire
The headline salary is rarely the full cost. In our experience, business owners comparing the two models often forget to add these on top of the base salary figure before they compare it with an outsourced quote.
What sits on top of the base salary
- Employer National Insurance contributions
- Pension contributions (a minimum is required under UK auto-enrolment rules)
- Recruitment costs, whether agency fees or the time spent hiring
- Onboarding and ongoing training, particularly for security and new platforms
- Sick leave and holiday cover, when the only IT person is unavailable
- Monitoring tools, licences and security software the individual needs to do the job properly
A junior in-house IT hire in the UK typically costs £30,000 to £40,000 a year in salary alone, before any of the above is added, and that figure rises quickly for someone experienced enough to cover security, networking and cloud on their own. Compare that with outsourced IT support, which typically runs £40 to £100 per user per month in 2026. For a business of 15 to 20 staff, that fee usually buys a full team rather than one generalist, which is why outsourcing tends to work out more cost-effective until a business is large enough to keep several IT staff fully occupied.

Where In-House IT Support Makes Sense
1In-house tends to work well when
- You’re large enough to justify two or more IT staff, so cover doesn’t depend on one person
- You run highly specific, on-premises infrastructure that benefits from daily, hands-on knowledge
- Your sector has strict data residency or access requirements that call for direct employment
- IT is central enough to your product or service that it needs to sit inside the business
2Outsourced tends to work well when
- You’re a small or medium business without the volume of work to keep an in-house team fully occupied
- You want predictable monthly costs rather than a variable staffing overhead
- You need broader security and specialist cover than one generalist can realistically provide
- Your headcount changes often enough that scaling support up or down matters
Why Many Growing Businesses End Up With a Hybrid
It doesn’t have to be all one or the other. A common pattern among growing UK businesses is a single in-house IT contact who understands the business day to day, backed by an outsourced provider for specialist cover, 24/7 monitoring, security and overflow support. This gives you a familiar face on-site along with a team behind them, rather than leaving one person to cover everything alone.
This tends to suit businesses that are past the earliest small-business stage but not yet large enough to run a full internal IT department. If you’re in this position, worth reading alongside this is our guide on signs your business needs managed IT support, which covers how to spot when your current setup, whichever model it is, is no longer keeping up.
What We’d Check First When Advising on This Decision
When a UK business asks us to help them decide, we typically start with the same handful of questions before recommending either model.
- How many staff and devices need supporting now, and in two years’ time?
- What happens today if your only IT contact is unavailable for a week?
- Does your business handle sensitive data that needs specialist, ongoing security monitoring?
- Is your IT workload steady, or does it spike around specific projects and busy periods?
- Would you rather manage a direct employee, or manage a provider relationship and contract?
According to the Cyber Security Breaches Survey 2025/2026 from the Department for Science, Innovation and Technology and the Home Office, 43% of UK businesses identified a cyber security breach or attack in the last 12 months, equivalent to around 612,000 businesses. That’s a significant reason security coverage should weigh heavily in this decision, not just cost. The NCSC recommends checking that any IT provider you rely on can demonstrate recognised security certification, such as Cyber Essentials, as a baseline standard.
Frequently Asked Questions
Is outsourced IT support cheaper than hiring in-house?
For most small and medium UK businesses, yes. Once you add employer National Insurance, pension contributions, recruitment and training on top of a salary, an outsourced contract covering a team of specialists usually costs less than one in-house generalist, particularly for businesses under around 50 staff.
Can I have both in-house and outsourced IT support?
Yes, and it’s a common setup. Many businesses keep one in-house IT contact for day-to-day, on-site presence, and use an outsourced provider for specialist cover, 24/7 monitoring and overflow support. This is sometimes called a co-managed or hybrid model.
What happens to our data and systems if we switch from in-house to outsourced, or the other way round?
A reputable outsourced provider will carry out a full review of your existing systems before taking over support, and your business retains ownership of its data, licences and accounts throughout. If you’re moving from outsourced back to in-house, check your contract’s exit terms and confirm what handover documentation you’re entitled to.
At what size does in-house IT start to make more sense?
There’s no fixed number, but as a general guide, once a business has enough IT workload to keep two or more IT staff fully occupied, in-house support starts to look more cost-competitive, because you’re no longer comparing one salary against a whole outsourced team.
Does outsourced IT support mean losing control over our systems?
No. You still own your infrastructure, data and decisions. The provider carries out the day-to-day management and monitoring, but strategic choices, such as what software to adopt or when to upgrade hardware, remain with your business.
Not Sure Whether In-House or Outsourced IT Support Fits Your Business?
Tell us how your business currently handles IT and we’ll recommend a support model, in-house, outsourced or hybrid, that actually matches your size, budget and risk.
There’s no universally right answer between in-house and outsourced IT support. The right choice depends on your size, how specialised your systems are, and how much risk you’re comfortable carrying if your only IT contact is unavailable. Start from the true cost and cover you actually need, rather than the headline price of either option, and revisit the decision as your business grows.
