Every business hits this fork in the road eventually. The printer’s on fire (metaphorically, usually), someone’s clicked a phishing link, and the CRM has decided to take the afternoon off. Who do you call? For a growing number of UK small businesses, the honest answer is “I’m not entirely sure, and that’s the problem.”
The in-house versus outsourced IT debate gets treated like a personality test, as if you’re either a “control freak who wants staff on-site” or a “budget-obsessed outsourcer.” It’s neither. It’s a business decision with real numbers attached, and the right answer changes depending on your headcount, your risk profile, and how much you actually want to think about IT on a Tuesday afternoon.
There’s no universally correct answer here. But there is a correct answer for your business, right now, at your current size. Let’s work out what that looks like.
The framing decision: size, budget, and what you actually need
Before comparing pros and cons, it helps to be honest about three things: how many people you employ, what you can realistically spend, and how complex your IT actually is. A five-person design studio and a 45-person logistics firm have wildly different needs, even if both currently run IT off the back of “whoever’s good with computers.”
As a general rule, most small businesses find outsourced support more cost-effective and more scalable than building an internal team from scratch. That’s not an opinion pulled from thin air, it’s simply what happens when you compare a single salary against a shared team of specialists. But “most businesses” isn’t “your business,” so let’s break down what each model actually gives you.
In-house IT support: what you get, and what it costs you
Hiring an internal IT person feels intuitive. They’re there. They know your systems, your staff, and probably which desk has the dodgy monitor. There’s something reassuring about being able to walk over and say “it’s broken, please fix it” and watch it happen.
The genuine advantages:
- Direct control. Your IT person answers to you, sits in your meetings, and understands your culture without a briefing document.
- Fast physical response. Hardware dies, cables fray, someone spills coffee into a keyboard (it happens more than you’d think). An on-site person sorts this in minutes, not hours.
- Face-to-face priority setting. You can literally point at the problem and say “this one first.”
The genuine drawbacks:
- Cost. A single competent IT hire in the UK typically runs well north of £50,000 a year once you factor in salary, pension contributions, employer’s National Insurance, equipment, software licensing, and ongoing training. That’s a ballpark figure, not gospel, but it’s a realistic all-in estimate for one decent generalist. And that’s before you’ve covered specialist skills like cybersecurity or cloud architecture.
- Single point of failure. What happens when that person is on holiday? Off sick? Gives notice and leaves for a better offer, taking three years of undocumented tribal knowledge with them? Unless you’re paying for two or three people (which multiplies that £50k figure fast), you’ve got a coverage gap built into your business.
- Skills ceiling. One person, however good, cannot be simultaneously an expert in networking, cybersecurity, cloud migration, compliance, and end-user support. Nobody can. You end up with a generalist handling problems that really need a specialist.
Outsourced IT support (Managed Service Providers): what you get, and what you give up
Outsourcing flips the model. Instead of employing one person to do everything, you pay a fixed monthly fee to a provider who fields a whole team of specialists, backed by tools no single small business could justify buying alone.
The genuine advantages:
- Lower, predictable costs. Monthly fees typically undercut a single in-house salary while giving you access to an entire team, not one person. There’s no recruitment overhead, no redundancy pay if things don’t work out, no sudden equipment refresh bill.
- Broader expertise. Instead of one generalist, you get specialists in cybersecurity, cloud migration, compliance, and infrastructure, each doing the part they’re actually best at.
- Continuous coverage. Round-the-clock monitoring, holiday cover, sick leave cover, all built in as standard. Nobody’s “off” in a way that leaves you exposed.
The honest trade-off:
- Less day-to-day physical presence. Your provider isn’t sitting three desks away. Most issues get resolved remotely, and while good MSPs offer on-site visits when genuinely needed, it’s not the same as someone permanently in the building.
In-house IT vs outsourced IT support for small business: what actually changes
Here’s the comparison in its simplest form.
| Factor | In-House IT | Outsourced IT (MSP) |
|---|---|---|
| Typical annual cost | £50,000+ per hire, all-in | Predictable monthly fee, usually lower per head |
| Coverage during leave/sickness | Gap unless you hire multiple staff | Built in as standard |
| Range of expertise | Limited to one person’s skill set | Team of specialists across disciplines |
| Physical presence | On-site, immediate | Mostly remote, occasional on-site visits |
| Scalability | Requires new hires as you grow | Scales up or down with your plan |
| Risk of single point of failure | High | Low |
Reading that table, you can probably already guess which way most small businesses lean. But numbers on a page don’t capture everything, so let’s talk about why the risk side of this matters more than it used to.
Why “in-house can handle it” doesn’t stretch as far as it once did
Cybersecurity threats haven’t stayed still, and neither has the cost of getting caught out. The UK Government’s Cyber Security Breaches Survey 2025 found that businesses reporting a temporary loss of access to files or networks rose to 7%, up from 4% the previous year. That’s not a dramatic headline number, but it’s a genuine year-on-year increase, and it points to a wider trend: the threat landscape is shifting faster than a single in-house generalist can realistically keep pace with, purely because it’s their job to know everything at once. A dedicated security specialist, working as part of a wider team, has a much narrower and more current focus. That’s not a knock on in-house IT staff, it’s just maths. Nobody can be the best in the world at six different specialisms simultaneously.
The growing business angle: what changes past 50 employees
Here’s where things get more interesting, because the answer isn’t static as your business grows.
Under 50 employees: outsourcing tends to make the strongest financial and practical sense. You simply haven’t reached the size where a dedicated in-house team pays for itself. The volume of IT work doesn’t yet justify a full internal department, and the risk of relying on one or two people is disproportionately high relative to your size.
Over 50 employees: the picture starts to shift. Many businesses at this stage move toward a co-managed model, keeping a small internal IT presence (often one or two people who understand the business intimately) while pairing them with an outsourced partner who handles overflow capacity, specialist security work, and larger projects like migrations or compliance audits. It’s the best of both worlds done properly: someone in the building who knows your quirks, backed by a team that can scale up when a project demands it and scale back down when it doesn’t.
This is, frankly, exactly the kind of flexible arrangement that good outsourced providers should be offering as standard. At Your IT, for instance, the model is built to flex both ways: full outsourced support for businesses who don’t want or need an internal team, and co-managed arrangements for those who’ve grown past that point but still want the breadth and continuity an internal hire alone can’t provide. Good outsourced support shouldn’t force you into an all-or-nothing choice. It should adapt as you do.
Making the actual decision
So how do you decide, properly, without just going with your gut?
Start with a genuinely honest question: if your current IT person (or you, if that’s still the case) took two weeks off tomorrow with no laptop, what would break? If the answer makes you wince, that’s your single point of failure showing itself, and it’s worth taking seriously regardless of which model you’re leaning towards.
Next, do the maths properly rather than roughly. Add up what a full-time hire actually costs you, salary plus pension plus National Insurance plus kit plus training plus recruitment fees if you have to replace them in eighteen months (which, let’s be honest, happens more often than anyone likes to admit). Compare that total, not just the headline salary, against what a managed service actually covers for the same money.
Finally, be realistic about your growth trajectory over the next two to three years. If you’re sitting comfortably under 50 employees with no huge expansion plans, outsourcing will very likely serve you better on cost and coverage alone. If you’re pushing past that threshold, start thinking now about what a co-managed setup might look like, rather than waiting until the cracks show and you’re solving the problem under pressure.
There’s no prize for guessing right. There’s only the cost of guessing wrong, and that tends to show up at the worst possible moment, usually when someone’s on holiday and the server’s decided to have an opinion. If you’re weighing this up right now, it’s worth talking it through with a proper outsourced Your IT Department rather than trying to solve it alone over a weekend with a search engine and mounting panic.
