In-House vs Outsourced IT Support: Which Is Right for Your Kent Business?

27th May 2026

Your one IT person is drowning. Tickets pile up while a security patch waits another week. You are not sure whether to hire a second person or hand the lot to a managed provider.

Choosing between in-house vs outsourced IT support is one of the biggest operational decisions a 10 to 50 person business will make. Most online guides are written to sell you outsourcing.

This one is not. You will get real UK cost figures, honest pros and cons of both sides, and a simple framework to work out which model fits your business. We run an IT support company in Kent, but we will tell you when staying in-house is the smarter call.

What Is the Difference Between In-House and Outsourced IT Support?

In-house IT support is when you employ one or more IT staff directly on your payroll to handle all technology issues internally. Outsourced IT support, also called managed IT services, is when you contract an external company to handle your IT for a monthly fee, giving you access to a full team of specialists rather than a single employee.

Both models aim to keep your technology running, your data secure, and your staff productive. The difference is who delivers that, how broad their skills are, and how you pay for it.

In-House IT Support: Pros and Cons

In-house IT gives you a dedicated person who knows your business inside out. The trade-off is breadth, cost, and single-person risk.

Advantages of an In-House IT Team

Deep institutional knowledge of your systems and people.
Immediate physical presence in the office.
Full alignment with your culture and priorities.
Easy to involve in non-IT projects and planning.
Direct line management and control.

Disadvantages of In-House IT

One person cannot realistically be an expert in every modern IT discipline. Most internal hires are strong in two or three areas and weaker across the rest.

Single point of failure when they are on holiday, off sick, or resign.
No 24/7 cover without paying for overtime or a second hire.
Limited breadth across networks, cyber security, cloud, and backup.
Recruitment fees of 15 to 20 percent of salary, plus training costs.
Ongoing certification and tooling spend on top of salary.

Outsourced IT Support: Pros and Cons

Outsourced IT gives you a full team of specialists for a predictable monthly fee. The trade-off is less embedded knowledge and reliance on a contract.

Advantages of Outsourcing IT Support

Access to specialists across networks, cyber, cloud, and backup.
Predictable monthly cost with no recruitment risk.
Built-in cover for holiday, sickness, and out-of-hours.
24/7 monitoring and faster access to enterprise-grade tools.
Scales up or down without hiring or redundancy.

Disadvantages of Outsourcing IT

Less embedded in your day-to-day culture.
Response times depend on the SLA you sign.
On-site visits may not be within minutes.
You rely on a third party for critical systems.
Contract terms need careful review before signing.

The True Cost of In-House IT vs Outsourced IT in the UK

Outsourced IT support is usually cheaper than hiring in-house for businesses with 10 to 50 employees. A loaded in-house cost typically lands between £55,000 and £80,000 a year once you factor in salary, employer National Insurance, pension, holiday cover, training, and recruitment.

Most guides quote a salary figure and stop there. That is misleading. Here is the honest breakdown.

Real Cost of Hiring an In-House IT Manager in the UK

According to Reed salary data and Glassdoor UK, the typical UK IT manager earns between £45,000 and £60,000. An IT technician earns roughly £28,000 to £38,000.

That headline figure misses the real cost. Add employer National Insurance at 13.8 percent, pension contributions, paid holiday, training, and recruitment fees, and the true cost climbs significantly.

Cost Element	Typical Annual Cost (UK)
IT Manager base salary	£45,000 to £60,000
Employer NI (13.8%)	£6,200 to £8,300
Pension contribution (3% min)	£1,350 to £1,800
Training and certifications	£1,500 to £3,000
Recruitment (15 to 20% of salary)	£6,750 to £12,000 (year one)
Tools, licences, kit	£1,500 to £3,000
Total true cost (year one)	£62,300 to £88,100

Outsourced IT Support Cost in the UK

Most UK managed service providers charge per user, per month. For a 10 to 50 person business, expect £45 to £90 per user, per month, depending on what is included.

That covers a full team of engineers, 24/7 monitoring, security tooling, backup management, and usually unlimited remote support. For a 25-person firm, that lands between £13,500 and £27,000 a year.

The result: you typically get broader skills and more cover for less than half the loaded cost of one senior in-house hire.

Scalability	Slow, requires hiring	Adjust monthly
Best for	50+ staff, complex stacks	10 to 50 staff, growing firms

When Does In-House IT Make Sense?

Hiring in-house is the right call in specific situations. Here are the clearest signals.

You have 50 or more employees and are growing.
Your tech stack is highly bespoke or proprietary.
You work in a tightly regulated sector where embedded knowledge matters.
IT is core to your product, not just a support function.
Your leadership team needs daily strategic input on technology.

When Should a Small Business Outsource IT Support?

Outsourcing is the right call for most 10 to 50 person Kent firms. Here is when it makes the most sense.

You have 10 to 50 staff and one hire cannot cover the skill range.
IT is critical to your operations but not your core product.
You need 24/7 cover without paying for night shifts.
Your headcount is growing fast or unpredictably.
Cyber security and compliance pressure is rising and you cannot keep up.
Your current IT person is overloaded or about to leave.

The Hybrid IT Support Model: Often the Right Answer

Many Kent businesses in the 20 to 50 staff range get the best results from a hybrid model. One internal person handles first-line support, while an external MSP covers specialist work.

The internal lead deals with new starters, day-to-day user issues, and acts as the in-office face of IT. The MSP handles cyber security, cloud, backup, projects, and out-of-hours cover.

This split gives you embedded knowledge plus full skill breadth, usually for less than two senior in-house hires.

How to Decide: A Simple Framework

Answer these six questions honestly. The pattern of your answers will point you to the right model.

How many staff do you have? Under 20 leans outsourced. Over 50 leans in-house.
How fast are you growing? Fast growth favours outsourcing for flexibility.
How complex is your tech stack? Highly bespoke favours in-house.
How critical is uptime outside business hours? 24/7 needs favour outsourcing.
What are your compliance and cyber obligations? Heavy requirements favour outsourcing for breadth.
Do you have anyone capable internally today? If yes, consider hybrid. If no, lean outsourced.

If four or more answers lean one way, you have your answer. If they are split, the hybrid model is usually the right starting point.

What Does a Managed IT Service Provider Actually Include?

A managed IT service provider delivers a full IT function on a monthly contract. A typical UK MSP package for a 10 to 50 person business includes user support, 24/7 monitoring, cyber security, cloud management, backup and disaster recovery, and strategic IT planning, all delivered by a specialist team.

The best providers act like an extension of your team, not a faceless help desk. You should expect named engineers, clear SLAs, and proactive recommendations, not just ticket closures.

What We See When Kent Businesses Make the Switch

We recently onboarded a 30-person logistics firm in Maidstone that had run IT internally for years. Within the first month we found three lapsed software licences, an unencrypted backup, and a firewall still running on factory defaults.

None of this was their IT person’s fault. They were stretched across too many disciplines. According to the UK Government Cyber Security Breaches Survey, 50 percent of UK businesses reported a cyber breach or attack in the last 12 months, and most happen because of small gaps no single person can keep on top of.

This is the pattern we see most often. The in-house person is doing their best. The business has simply outgrown what one person can deliver.

The Bottom Line

There is no universal right answer. The right choice depends on your size, growth, stack complexity, and what you actually need covered.

For most 10 to 50 person Kent businesses, outsourced or hybrid IT delivers more skill, more cover, and lower risk than a single in-house hire. For larger or highly bespoke operations, in-house still wins.
