In-House IT vs Managed IT: Which Is Right for Your Business?

At some point, most growing businesses face the same question: do we hire our own IT person, or bring in an external managed IT support provider? Both can work well, but they suit very different situations, and the wrong choice tends to cost more than expected, either in money, in risk, or in both. This guide walks through what each option genuinely involves, what it costs in the UK today, and how to decide.

What “in-house IT” actually means

Hiring an IT person means bringing someone into your team with a salary, a desk, and responsibility for keeping your systems running. For many business owners there is real appeal in having someone physically present who knows the business inside out.

But the true cost of an in-house hire goes well beyond salary. A mid-level IT support engineer in the UK typically earns between £30,000 and £45,000 per year. Add employer National Insurance contributions, pension contributions, annual leave, training, and the software licences and tools they need to do the job, and the realistic annual cost is closer to £40,000 to £58,000 or more. For a business of 20 people, that translates to roughly £170 to £240 per user per month before any additional external support costs.

There are less obvious costs too. One person can only cover so much. When they are on holiday, off sick, or busy with one problem, everything else waits. A single IT generalist is unlikely to have deep expertise across cyber security, cloud infrastructure, compliance, telephony, and end-user support simultaneously. If something serious happens, such as a ransomware incident or a complex cloud migration, outside specialist help will almost certainly be needed on top.

What managed IT support actually covers

A managed IT support arrangement typically runs on a per-user, per-month contract covering helpdesk support, proactive monitoring, patch management, security tools, and agreed response times. Most UK businesses of 10 to 100 staff pay between £60 and £90 per user per month for a comprehensive package, though pricing varies depending on the scope of services, the provider’s certifications, and the complexity of the environment.

The key difference is that you are accessing a team rather than an individual. A good managed provider brings engineers with different specialisms, including cyber security, cloud platforms, compliance, and infrastructure, without you having to employ each one separately. Monitoring runs continuously across your environment, patches are applied on schedule, and if something goes wrong at 10pm, there is a process to handle it.

Where is the break-even point?

For most UK businesses, the financial break-even between in-house and outsourced IT sits somewhere between 50 and 75 users. Below that threshold, a managed provider is almost always more cost-effective once you account for the true employment cost and the breadth of skills you realistically need. Above it, a combination of in-house staff, often a technical coordinator or IT manager, supported by an external managed provider tends to be the most practical arrangement.

Cost is only part of the picture, though. A business handling sensitive client data, aiming for Cyber Essentials certification, or operating in a regulated sector such as healthcare, finance, or legal has a stronger argument for choosing a provider with documented security expertise and formal accreditation, regardless of size.

What in-house IT genuinely struggles with

It is worth being honest about where a single internal hire tends to fall short, not because in-house IT is a bad idea, but because the limitations are predictable:

• Cover. Holidays, sickness, and resignation all create gaps. A managed provider has a team behind them.
• Breadth. Cyber security, cloud, compliance, telephony, and day-to-day support are four different disciplines. Few individuals are strong across all of them.
• Scale. A managed provider’s tooling, monitoring platforms, and security infrastructure are shared across many clients, spreading the cost of enterprise-grade tools across a much lower per-user fee.
• Continuity. If your IT person leaves, you lose institutional knowledge and face a recruitment gap. A managed provider continues regardless.

Questions worth asking before you decide

If you are currently weighing up a hire against a managed arrangement, these help to focus the decision:

• What is the true annual cost of a hire, including NI, pension, tools, training, and cover?
• What do we actually need IT support to do, and does one person cover all of it?
• How would we handle a serious cyber incident, or an extended absence?
• Are we working towards any compliance standards, and does our current IT arrangement support that?
• Do we want IT to function as a managed cost, or as a strategic function that helps the business grow?

What a good managed IT relationship looks like

The best managed IT arrangements are not simply glorified helpdesks. Done well, IT consulting within a managed relationship means your provider understands your business, helps you plan for technology changes, and escalates issues proactively, rather than waiting for you to log a ticket.

At System Force IT, we work with businesses across Gloucestershire and the wider UK that have moved from ad-hoc or in-house arrangements to a fully managed model. Some had a single IT person who left; others outgrew a break-fix arrangement; others simply wanted the security and compliance expertise that a team provides. We are happy to be transparent about what the transition looks like, what it costs, and whether it is the right fit for where you are now.

We also hold UKAS-accredited ISO/IEC 27001 certification, which means our own security management is independently audited, and that our clients benefit from a provider that is held to a verifiable standard, not just a promise.
